A safety belt that is improperlyrouted, not properly attached,or twisted will not provide theprotection needed in a crash.The person wearing the belt couldbe seriously injured. After raisingthe rear seatback, always checkto be sure that the safety beltsare properly routed and attached,and are not twisted.

Safety BeltsThis section of the manualdescribes how to use safety beltsproperly. It also describes somethings not to do with safety belts.

{ WARNING

Do not let anyone ride wherea safety belt cannot be wornproperly. In a crash, if you oryour passenger(s) are notwearing safety belts, the injuriescan be much worse. You can hitthings inside the vehicle harderor be ejected from the vehicle.You and your passenger(s) canbe seriously injured or killed.In the same crash, you mightnot be, if you are buckled up.Always fasten your safety belt,and check that your passenger(s)are restrained properly too.



{ WARNING

People riding on the tailgate(if equipped) can easily lose theirbalance and fall even when thevehicle is operated at low speeds.Falling from a moving vehicle mayresult in serious injuries or death.

{ WARNING

It is extremely dangerous to ridein a cargo area, inside or outsideof a vehicle. In a collision, peopleriding in these areas are morelikely to be seriously injured orkilled. Do not allow people to ridein any area of your vehicle thatis not equipped with seats andsafety belts. Be sure everyone inthe vehicle is in a seat and usinga safety belt properly.

This vehicle has indicators as areminder to buckle the safety belts.See Safety Belt Reminders onpage 5‑19 for additional information.

In most states and in all Canadianprovinces, the law requires wearingsafety belts. Here is why:

You never know if you will be ina crash. If you do have a crash,you do not know if it will be aserious one.

A few crashes are mild, and somecrashes can be so serious thateven buckled up, a person wouldnot survive. But most crashesare in between. In many of them,people who buckle up can surviveand sometimes walk away. Withoutsafety belts they could have beenbadly hurt or killed.

After more than 40 years of safetybelts in vehicles, the facts are clear.In most crashes buckling up doesmatter ... a lot!

Why Safety Belts Work

When you ride in or on anything,you go as fast as it goes.

Take the simplest vehicle. Supposeit is just a seat on wheels.



Put someone on it. Get it up to speed. Then stop thevehicle. The rider does not stop.

The person keeps going untilstopped by something. In a realvehicle, it could be the windshield...



or the instrument panel... or the safety belts!

With safety belts, you slow downas the vehicle does. You get moretime to stop. You stop over moredistance, and your strongest bonestake the forces. That is why safetybelts make such good sense.

Questions and Answers AboutSafety Belts

Q: Will I be trapped in the vehicleafter a crash if I am wearing asafety belt?

A: You could be—whether youare wearing a safety belt ornot. But your chance of beingconscious during and after anaccident, so you can unbuckleand get out, is much greater ifyou are belted. And you canunbuckle a safety belt, even ifyou are upside down.



Q: If my vehicle has airbags, whyshould I have to wear safetybelts?

A: Airbags are supplementalsystems only; so they workwith safety belts— not insteadof them. Whether or not anairbag is provided, all occupantsstill have to buckle up to get themost protection. That is true notonly in frontal collisions, butespecially in side and othercollisions.

Q: If I am a good driver, and Inever drive far from home,why should I wear safetybelts?

A: You may be an excellent driver,but if you are in a crash— evenone that is not your fault— youand your passenger(s) can behurt. Being a good driver doesnot protect you from thingsbeyond your control, suchas bad drivers.

Most accidents occur within40 km (25miles) of home.And the greatest number ofserious injuries and deathsoccur at speeds of less than65 km/h (40 mph).

Safety belts are for everyone.

How to Wear Safety BeltsProperlyThis section is only for people ofadult size.

Be aware that there are specialthings to know about safety beltsand children. And there are differentrules for smaller children andinfants. If a child will be riding inthe vehicle, see Older Children onpage 3‑49 or Infants and YoungChildren on page 3‑51. Follow thoserules for everyone's protection.

It is very important for all occupantsto buckle up. Statistics show thatunbelted people are hurt moreoften in crashes than those whoare wearing safety belts.

Occupants who are not buckled upcan be thrown out of the vehicle in acrash. And they can strike others inthe vehicle who are wearing safetybelts.



First, before you or yourpassenger(s) wear a safety belt,there is important information youshould know.

Sit up straight and always keepyour feet on the floor in front of you.The lap part of the belt should be

worn low and snug on the hips,just touching the thighs. In a crash,this applies force to the strongpelvic bones and you would beless likely to slide under the lapbelt. If you slid under it, the beltwould apply force on your abdomen.This could cause serious or evenfatal injuries. The shoulder beltshould go over the shoulder andacross the chest. These parts ofthe body are best able to takebelt restraining forces.

The shoulder belt locks if there is asudden stop or crash.

Q: What is wrong with this?

A: The shoulder belt is too loose.It will not give as muchprotection this way.



{ WARNING

You can be seriously hurt if theshoulder belt is too loose. In acrash, you would move forwardtoo much, which could increaseinjury. The shoulder belt should fitsnugly against your body.


A: The lap belt is too loose.It will not give nearly asmuch protection this way.

{ WARNING

You can be seriously hurt if thelap belt is too loose. In a crash,you could slide under the lapbelt and apply force on yourabdomen. This could causeserious or even fatal injuries.The lap belt should be wornlow and snug on the hips,just touching the thighs.




A: The belt is buckled in the wrongbuckle.

{ WARNING

You can be seriously injuredif the belt is buckled in the wrongplace like this. In a crash, the beltwould go up over your abdomen.The belt forces would be there,not on the pelvic bones. Thiscould cause serious internalinjuries. Always buckle the beltinto the buckle nearest you.


A: The belt is over an armrest.



{ WARNING

You can be seriously injured if thebelt goes over an armrest likethis. The belt would be much toohigh. In a crash, you can slideunder the belt. The belt forcewould then be applied on theabdomen, not on the pelvicbones, and that could causeserious or fatal injuries. Be surethe belt goes under the armrests.


A: The shoulder belt is worn underthe arm. It should be worn overthe shoulder at all times.

{ WARNING

You can be seriously injuredif you wear the shoulder beltunder your arm. In a crash, yourbody would move too far forward,which would increase the chanceof head and neck injury. Also,the belt would apply too muchforce to the ribs, which are notas strong as shoulder bones.You could also severely injureinternal organs like your liver orspleen. The shoulder belt shouldgo over the shoulder and acrossthe chest.




A: The belt is behind the body.

{ WARNING

You can be seriously injured bynot wearing the lap-shoulderbelt properly. In a crash, youwould not be restrained by theshoulder belt. Your body couldmove too far forward increasingthe chance of head and neckinjury. You might also slideunder the lap belt. The beltforce would then be applied righton the abdomen. That couldcause serious or fatal injuries.The shoulder belt should goover the shoulder and acrossthe chest.


A: The belt is twisted acrossthe body.

{ WARNING

You can be seriously injured by atwisted belt. In a crash, you wouldnot have the full width of the beltto spread impact forces. If a beltis twisted, make it straight so itcan work properly, or ask yourdealer to fix it.



Lap-Shoulder BeltIf the vehicle is a regular cab,then all seating positions in thevehicle have a lap-shoulder belt.If the vehicle is a crew or extendedcab, then all seating positions inthe vehicle have a lap-shoulderbelt except for the center frontpassenger position (if equipped),which has a lap belt. See Lap Belt(Crew and Extended Cab) onpage 3‑26 for more information.

The following instructions explainhow to wear a lap-shoulder beltproperly.

1. Adjust the seat, if the seat isadjustable, so you can sit upstraight. To see how, see “Seats”in the Index.

2. Pick up the latch plate and pullthe belt across you. Do not let itget twisted.

The lap-shoulder belt may lock ifyou pull the belt across you veryquickly. If this happens, let thebelt go back slightly to unlock it.Then pull the belt across youmore slowly.

If the shoulder portion of apassenger belt is pulled outall the way, the child restraintlocking feature may be engaged.If this happens, let the belt goback all the way and start again.

Engaging the child restraintlocking feature may affect thepassenger sensing system,if equipped. See PassengerSensing System on page 3‑40for more information.

If the belt stops before it reachesthe buckle, when using thelap-shoulder belt in a rear centerseating position of a crew-cab,tilt the latch plate and keeppulling the safety belt until itcan be buckled.



3. Push the latch plate into thebuckle until it clicks.

Pull up on the latch plate tomake sure it is secure. If the beltis not long enough, see SafetyBelt Extender on page 3‑27.

If the latch plate will not go fullyinto the buckle, check if thecorrect buckle is being used.

Position the release button onthe buckle so that the safety beltcould be quickly unbuckled ifnecessary.

4. If equipped with a shoulder beltheight adjuster, move it to theheight that is right for you. See“Shoulder Belt Height Adjuster”later in this section.

5. To make the lap part tight, pullup on the shoulder belt.

It may be necessary to pullstitching on the safety beltthrough the latch plate to fullytighten the lap belt on smalleroccupants.

To unlatch the belt, push the buttonon the buckle. The belt shouldreturn to its stowed position.

Before a door is closed, be sure thesafety belt is out of the way. If adoor is slammed against a safetybelt, damage can occur to both thesafety belt and the vehicle.



Shoulder Belt Height Adjuster

The vehicle has a shoulder beltheight adjuster for the driver andright front passenger.

Adjust the height so the shoulderportion of the belt is on theshoulder and not falling off of it.The belt should be close to, butnot contacting, the neck. Impropershoulder belt height adjustmentcould reduce the effectiveness ofthe safety belt in a crash. See Howto Wear Safety Belts Properly onpage 3‑15.

Regular and Crew Cab

To move the adjuster down for theregular and crew cabs, squeezethe buttons (A) on the sides of theheight adjuster and move the heightadjuster to the desired position.

Extended Cab

On the extended cab, push downon the release button (A) and movethe height adjuster to the desiredposition.

You can move the adjuster up justby pushing up on the shoulder beltguide.

After you move the adjuster towhere you want it, try to move itdown, without squeezing the buttonsfor the regular and crew cabs,or without pushing the releasebutton for extended cabs, to makesure it has locked into position.



Safety Belt Pretensioners

This vehicle has safety beltpretensioners for front outboardoccupants. Although the safetybelt pretensioners cannot be seen,they are part of the safety beltassembly. They can help tighten thesafety belts during the early stagesof a moderate to severe frontal,near frontal, or rear crash if thethreshold conditions for pretensioneractivation are met. And, if yourvehicle has side impact airbags,safety belt pretensioners can helptighten the safety belts in a sidecrash or a rollover event.

Pretensioners work only once.If the pretensioners activate in acrash, they will need to be replaced,and probably other new parts forthe vehicle's safety belt system.See Replacing Safety Belt SystemParts After a Crash on page 3‑28.

Rear Safety Belt ComfortGuides

This vehicle may have rear shoulderbelt comfort guides. If not, theyare available through your dealer.The guides may provide addedsafety belt comfort for older childrenwho have outgrown booster seatsand for some adults. When installedand properly adjusted, the comfortguide positions the belt away fromthe neck and head.

Here is how to install a comfortguide to the shoulder belt:

1. Remove the guide from itsstorage clip on the interior body.

2. Place the guide over the beltand insert the two edges of thebelt into the slots of the guide.



3. Be sure that the belt isnot twisted and it lies flat.The elastic cord must be underthe belt and the guide on top.

{ WARNING

A safety belt that is not properlyworn may not provide theprotection needed in a crash.The person wearing the belt couldbe seriously injured. The shoulderbelt should go over the shoulderand across the chest. These partsof the body are best able to takebelt restraining forces.

4. Buckle, position, and releasethe safety belt as describedpreviously in this section. Makesure the shoulder portion of thebelt is on the shoulder and notfalling off of it. The belt shouldbe close to, but not contacting,the neck.

To remove and store the comfortguide, squeeze the belt edgestogether so that the safety belt canbe removed from the guide. Slidethe guide onto the storage clip.



Safety Belt Use DuringPregnancySafety belts work for everyone,including pregnant women. Like alloccupants, they are more likely tobe seriously injured if they do notwear safety belts.

A pregnant woman should weara lap-shoulder belt, and the lapportion should be worn as lowas possible, below the rounding,throughout the pregnancy.

The best way to protect the fetus isto protect the mother. When a safetybelt is worn properly, it is more likelythat the fetus will not be hurt in acrash. For pregnant women, as foranyone, the key to making safetybelts effective is wearing themproperly.

Lap Belt (Crew andExtended Cab)This section is only for the lap belt.To learn how to wear a lap-shoulderbelt, see Lap-Shoulder Belt onpage 3‑21.

Your vehicle may have a centerseating position. When you sit inthe center front seating position,you have a lap safety belt, whichhas no retractor.

To make the belt longer, tilt the latchplate and pull it along the belt.

Buckle, position, and release itthe same way as the lap part of alap-shoulder belt.



To make the belt shorter, pull its freeend as shown until the belt is snug.

If the belt is not long enough, seeSafety Belt Extender on page 3‑27.

Make sure the release button on thebuckle is positioned so you wouldbe able to unbuckle the safety beltquickly if necessary.

Safety Belt ExtenderIf the vehicle's safety belt will fastenaround you, you should use it.

But if a safety belt is not longenough, your dealer will order youan extender. When you go in toorder it, take the heaviest coat youwill wear, so the extender will belong enough for you. To help avoidpersonal injury, do not let someoneelse use it, and use it only for theseat it is made to fit. The extenderhas been designed for adults.Never use it for securing child seats.To wear it, attach it to the regularsafety belt. For more information,see the instruction sheet that comeswith the extender.

Safety System CheckNow and then, check that the safetybelt reminder light, safety belts,buckles, latch plates, retractors,and anchorages are workingproperly. Look for any other looseor damaged safety belt system partsthat might keep a safety belt systemfrom doing its job. See your dealerto have it repaired. Torn or frayedsafety belts may not protect you ina crash. They can rip apart underimpact forces. If a belt is torn orfrayed, get a new one right away.

Make sure the safety belt reminderlight is working. See Safety BeltReminders on page 5‑19 for moreinformation.

Keep safety belts clean and dry.See Safety Belt Care on page 3‑28.



Safety Belt CareKeep belts clean and dry.

{ WARNING

Do not bleach or dye safety belts.It may severely weaken them.In a crash, they might not be ableto provide adequate protection.Clean safety belts only with mildsoap and lukewarm water.

Replacing Safety BeltSystem Parts After aCrash

{ WARNING

A crash can damage the safetybelt system in the vehicle.A damaged safety belt systemmay not properly protect theperson using it, resulting inserious injury or even death ina crash. To help make sure thesafety belt systems are workingproperly after a crash, have theminspected and any necessaryreplacements made as soon aspossible.

After a minor crash, replacement ofsafety belts may not be necessary.But the safety belt assemblies thatwere used during any crash mayhave been stressed or damaged.See your dealer to have the safetybelt assemblies inspected orreplaced.

New parts and repairs may benecessary even if the safety beltsystem was not being used at thetime of the crash.

Have the safety belt pretensionerschecked if the vehicle has been in acrash, or if the airbag readiness lightstays on after you start the vehicleor while you are driving. See AirbagReadiness Light on page 5‑20.



Airbag SystemThe vehicle has the followingairbags:. A frontal airbag for the driver.. A frontal airbag for the right front

passenger.

The vehicle may have the followingairbags:. A seat‐mounted side impact

airbag for the driver.. A seat‐mounted side impact

airbag for the right frontpassenger.

. A roof-rail airbag for the driverand the passenger seateddirectly behind the driver.

. A roof-rail airbag for the rightfront passenger and the personseated directly behind the rightfront passenger.

All of the airbags in the vehicle willhave the word AIRBAG embossedin the trim or on an attached labelnear the deployment opening.

For frontal airbags, the wordAIRBAG will appear on the middlepart of the steering wheel for thedriver and on the instrument panelfor the right front passenger.

With seat‐mounted side impactairbags, the word AIRBAG willappear on the side of the seatbackclosest to the door.

With roof-rail airbags, the wordAIRBAG will appear along theheadliner or trim.

Airbags are designed to supplementthe protection provided by safetybelts. Even though today's airbagsare also designed to help reducethe risk of injury from the force of aninflating bag, all airbags must inflatevery quickly to do their job.

Here are the most important thingsto know about the airbag system:

{ WARNING

You can be severely injured orkilled in a crash if you are notwearing your safety belt— evenif you have airbags. Airbags aredesigned to work with safetybelts, but do not replace them.Also, airbags are not designedto deploy in every crash. In somecrashes safety belts are your onlyrestraint. See When Should anAirbag Inflate? on page 3‑32.

Wearing your safety belt during acrash helps reduce your chanceof hitting things inside the vehicleor being ejected from it. Airbagsare “supplemental restraints” tothe safety belts. Everyone in yourvehicle should wear a safety beltproperly—whether or not there isan airbag for that person.



{ WARNING

Airbags inflate with great force,faster than the blink of an eye.Anyone who is up against, orvery close to, any airbag when itinflates can be seriously injuredor killed. Do not sit unnecessarilyclose to any airbag, as you wouldbe if you were sitting on the edgeof the seat or leaning forward.Safety belts help keep you inposition before and during acrash. Always wear a safety belt,even with airbags. The drivershould sit as far back as possiblewhile still maintaining control ofthe vehicle.

Occupants should not lean onor sleep against the door or sidewindows in seating positions withseat-mounted side impact airbagsand/or roof-rail airbags.

{ WARNING

Children who are up against,or very close to, any airbagwhen it inflates can be seriouslyinjured or killed. Airbags pluslap-shoulder belts offer protectionfor adults and older children,but not for young children andinfants. Neither the vehiclesafety belt system nor its airbagsystem is designed for them.Young children and infantsneed the protection that a childrestraint system can provide.Always secure children properlyin the vehicle. To read how, seeOlder Children on page 3‑49 orInfants and Young Children onpage 3‑51.

There is an airbag readiness lighton the instrument panel cluster,which shows the airbag symbol.

The system checks the airbagelectrical system for malfunctions.The light tells you if there is anelectrical problem. See AirbagReadiness Light on page 5‑20for more information.



Where Are the Airbags?

The driver airbag is in the middle ofthe steering wheel.

The right front passenger airbagis in the instrument panel on thepassenger side.

Driver Side Shown, PassengerSide Similar

If the vehicle has seat‐mounted sideimpact airbags for the driver andright front passenger, they are inthe side of the seatbacks closestto the door.



Driver Side Shown, PassengerSide Similar

If the vehicle has roof-rail airbagsfor the driver, right front passenger,and second row outboardpassengers, they are in the ceilingabove the side windows.

{ WARNING

If something is between anoccupant and an airbag, theairbag might not inflate properlyor it might force the object intothat person causing severeinjury or even death. The pathof an inflating airbag must bekept clear. Do not put anythingbetween an occupant and anairbag, and do not attach or putanything on the steering wheelhub or on or near any otherairbag covering.

Do not use seat accessoriesthat block the inflation path of aseat-mounted side impact airbag.

Never secure anything to theroof of a vehicle with roof-railairbags by routing a rope or tiedown through any door or windowopening. If you do, the path of aninflating roof-rail airbag will beblocked.

When Should an AirbagInflate?Frontal airbags are designedto inflate in moderate to severefrontal or near-frontal crashesto help reduce the potential forsevere injuries mainly to the driver'sor right front passenger's headand chest. However, they areonly designed to inflate if theimpact exceeds a predetermineddeployment threshold. Deploymentthresholds are used to predict howsevere a crash is likely to be in timefor the airbags to inflate and helprestrain the occupants.

Whether the frontal airbags willor should deploy is not based onhow fast your vehicle is traveling.It depends largely on what you hit,the direction of the impact, and howquickly your vehicle slows down.



Frontal airbags may inflateat different crash speeds.For example:. If the vehicle hits a stationary

object, the airbags could inflateat a different crash speed than ifthe vehicle hits a moving object.

. If the vehicle hits an object thatdeforms, the airbags couldinflate at a different crash speedthan if the vehicle hits an objectthat does not deform.

. If the vehicle hits a narrow object(like a pole), the airbags couldinflate at a different crash speedthan if the vehicle hits a wideobject (like a wall).

. If the vehicle goes into an objectat an angle, the airbags couldinflate at a different crash speedthan if the vehicle goes straightinto the object.

Thresholds can also vary withspecific vehicle design.

Frontal airbags are not intended toinflate during vehicle rollovers, rearimpacts, or in many side impacts.

If the GVWR (Gross Vehicle WeightRating) of your vehicle is 3 855 kg(8,500 lb) or above, the vehicle hassingle stage airbags. If the GVWRis below 3 855 kg (8,500 lb) thenthe vehicle has dual stage airbags.Vehicles with a full bench seat areequipped with single state airbags.You can find the GVWR on thecertification label on the rear edgeof the driver door. See VehicleLoad Limits on page 9‑25 formore information.

The vehicle may have dual‐stagefrontal airbags. Dual-stage airbagsadjust the restraint according tocrash severity. The vehicle haselectronic frontal sensors, whichhelp the sensing system distinguishbetween a moderate frontal impactand a more severe frontal impact.For moderate frontal impacts,dual-stage airbags inflate at alevel less than full deployment.For more severe frontal impacts,full deployment occurs.

Vehicles with dual stage airbagsalso have seat position sensorswhich enable the sensing systemto monitor the position of the driverseat (all models), and on crew caband extended cab models the rightfront passenger seat on light dutymodels only. The seat positionsensor provides information that isused to determine if the airbagsshould deploy at a reduced levelor at full deployment.



The vehicle may or may not haveseat‐mounted side impact androof-rail airbags. See Airbag Systemon page 3‑29. Seat‐mounted sideimpact and roof-rail airbags areintended to inflate in moderate tosevere side crashes. In addition,these roof-rail airbags are intendedto inflate during a rollover or in asevere frontal impact. Seat‐mountedside impact and roof-rail airbags willinflate if the crash severity is abovethe system's designed thresholdlevel. The threshold level can varywith specific vehicle design.

Roof-rail airbags are notintended to inflate in rear impacts.A seat‐mounted side impact airbagis intended to deploy on the sideof the vehicle that is struck. Bothroof-rail airbags will deploy wheneither side of the vehicle is struck,or if the sensing system predictsthat the vehicle is about to roll over,or in a severe frontal impact.

In any particular crash, no onecan say whether an airbag shouldhave inflated simply because ofthe damage to a vehicle or becauseof what the repair costs were.For frontal airbags, inflation isdetermined by what the vehicle hits,the angle of the impact, and howquickly the vehicle slows down.For seat‐mounted side impact androof-rail airbags, deployment isdetermined by the location andseverity of the side impact. In arollover event, roof-rail airbagdeployment is determined bythe direction of the roll.

What Makes an AirbagInflate?In a deployment event, the sensingsystem sends an electrical signaltriggering a release of gas from theinflator. Gas from the inflator fills theairbag causing the bag to break outof the cover and deploy. The inflator,the airbag, and related hardware areall part of the airbag module.

Frontal airbag modules are locatedinside the steering wheel andinstrument panel. For vehicles withseat‐mounted side impact airbags,there are airbags modules in theside of the front seatbacks closestto the door. For vehicles withroof-rail airbags, there are airbagmodules in the ceiling of the vehicle,near the side windows that haveoccupant seating positions.



How Does an AirbagRestrain?In moderate to severe frontalor near frontal collisions, evenbelted occupants can contact thesteering wheel or the instrumentpanel. In moderate to severe sidecollisions, even belted occupantscan contact the inside of thevehicle.

Airbags supplement the protectionprovided by safety belts.Frontal airbags distribute theforce of the impact more evenlyover the occupant's upper body,stopping the occupant moregradually. Seat‐mounted sideimpact and roof-rail airbagsdistribute the force of theimpact more evenly over theoccupant's upper body.

Rollover capable roof-rail airbagsare designed to help containthe head and chest of occupantsin the outboard seating positionsin the first and second rows.The rollover capable roof-railairbags are designed to helpreduce the risk of full or partialejection in rollover events, althoughno system can prevent all suchejections.

But airbags would not help inmany types of collisions, primarilybecause the occupant's motionis not toward those airbags.See When Should an AirbagInflate? on page 3‑32 for moreinformation.

Airbags should never be regardedas anything more than a supplementto safety belts.

What Will You See Afteran Airbag Inflates?After the frontal airbags andseat-mounted side impact airbagsinflate, they quickly deflate, soquickly that some people may noteven realize an airbag inflated.Roof-rail airbags may still be at leastpartially inflated for some time afterthey deploy. Some components ofthe airbag module may be hot forseveral minutes. For location of theairbag modules, see What Makesan Airbag Inflate? on page 3‑34.

The parts of the airbag thatcome into contact with youmay be warm, but not too hotto touch. There may be somesmoke and dust coming fromthe vents in the deflated airbags.



Airbag inflation does not preventthe driver from seeing out of thewindshield or being able to steer thevehicle, nor does it prevent peoplefrom leaving the vehicle.

{ WARNING

When an airbag inflates, theremay be dust in the air. This dustcould cause breathing problemsfor people with a history ofasthma or other breathing trouble.To avoid this, everyone in thevehicle should get out as soonas it is safe to do so. If you havebreathing problems but cannotget out of the vehicle after anairbag inflates, then get fresh airby opening a window or a door.If you experience breathingproblems following an airbagdeployment, you should seekmedical attention.

The vehicle may have a featurethat may automatically unlock thedoors, turn on the interior lamps andhazard warning flashers, and shutoff the fuel system after the airbagsinflate. You can lock the doors, turnoff the interior lamps and hazardwarning flashers by using thecontrols for those features.

{ WARNING

A crash severe enough to inflatethe airbags may have alsodamaged important functionsin the vehicle, such as the fuelsystem, brake and steeringsystems, etc. Even if the vehicleappears to be drivable after amoderate crash, there may beconcealed damage that couldmake it difficult to safely operatethe vehicle.

Use caution if you should attemptto restart the engine after a crashhas occurred.

In many crashes severe enough toinflate the airbag, windshields arebroken by vehicle deformation.Additional windshield breakagemay also occur from the rightfront passenger airbag.. Airbags are designed to inflate

only once. After an airbaginflates, you will need somenew parts for the airbag system.If you do not get them, theairbag system will not be thereto help protect you in anothercrash. A new system will includeairbag modules and possiblyother parts. The service manualfor your vehicle covers the needto replace other parts.



. The vehicle has a crash sensingand diagnostic module whichrecords information after acrash. See Vehicle DataRecording and Privacy onpage 13‑17 and Event DataRecorders on page 13‑17.

. Let only qualified technicianswork on the airbag systems.Improper service can mean thatan airbag system will not workproperly. See your dealer forservice.

Airbag On-Off SwitchIf one of the switches pictured in thefollowing illustrations is located inthe glove box, the vehicle has anairbag on-off switch that you canuse to manually turn on or off theright front passenger airbag.

United States

Canada and Mexico

If the vehicle does not have anairbag off switch, it may havea passenger sensing system.See Passenger Sensing System onpage 3‑40.



This switch should only be turnedto the off position if the person inthe right front passenger positionis a member of a passenger riskgroup identified by the nationalgovernment as follows:

Infant. An infant (less than1 year old) must ride in thefront seat because:. My vehicle has no rear seat;. My vehicle has a rear seat

too small to accommodate arear-facing infant seat; or

. The infant has a medicalcondition which, according tothe infant's physician, makes itnecessary for the infant to ride inthe front seat so that the drivercan constantly monitor thechild's condition.

Child age 1 to 12. A childage 1 to 12 must ride in thefront seat because:. My vehicle has no rear seat;. Although children ages 1 to 12

ride in the rear seat(s) wheneverpossible, children ages 1 to 12sometimes must ride in the frontbecause no space is available inthe rear seat(s) of my vehicle; or

. The child has a medicalcondition which, according tothe child's physician, makes itnecessary for the child to ride inthe front seat so that the drivercan constantly monitor thechild's condition.

Medical Condition. A passengerhas a medical condition which,according to his or her physician:. Causes the passenger airbag

to pose a special risk for thepassenger; and

. Makes the potential harm fromthe passenger airbag in a crashgreater than the potential harmfrom turning off the airbag andallowing the passenger, even ifbelted, to hit the dashboard orwindshield in a crash.

{ WARNING

If the right front passengerairbag is turned off for aperson who is not in a riskgroup identified by the nationalgovernment, that personwill not have the extra protection

To turn off the right front passengerairbag, insert the ignition key intothe switch, push in, and move theswitch to the off position.

The word OFF or the off symbolwill come on in the passengerairbag status indicator located inthe overhead console to let youknow that the right front passengerairbag is off, after the system check

is completed. The airbag off lightwill come on and stay on to let youknow that the right front passenger'sairbag is off. See Airbag On-OffLight on page 5‑21.

{ WARNING

If the airbag readiness lightever comes on and stays on, itmeans that something may bewrong with the airbag system.For example, the right frontpassenger airbag could inflateeven though the airbag on-offswitch is turned off.

To help avoid injury to yourself orothers, have the vehicle servicedright away. See Airbag ReadinessLight on page 5‑20 for moreinformation, including importantsafety information.



United States Canada and Mexico

To turn the right front passengerairbag on again, insert the ignitionkey into the switch, push in, andmove the switch to the on position.

The right front passenger frontalairbag is now enabled (may inflate).See Airbag On-Off Light onpage 5‑21 for more information.

Passenger SensingSystemIf the vehicle has one of theindicators pictured in the followingillustrations, then the vehicle hasa passenger sensing system forthe right front passenger position,unless there is an airbag off switchlocated in the glove box. If thereis an airbag off switch, the vehicledoes not have a passenger sensingsystem. See Airbag On-Off Switchon page 3‑37 for more information.

The passenger airbag statusindicator will be visible on theoverhead console when thevehicle is started.

In addition, if the vehicle has apassenger sensing system for theright front passenger position, thelabel on the vehicle's sun visorsrefers to “ADVANCED AIRBAGS”.



United States

Canada and Mexico

The words ON and OFF, or thesymbol for on and off, will be visibleduring the system check. If youare using remote start to start thevehicle from a distance, if equipped,you may not see the system check.

When the system check iscomplete, either the word ON orOFF, or the symbol for on or off, willbe visible. See Passenger AirbagStatus Indicator on page 5‑23.

The passenger sensing system willturn off the right front passengerfrontal airbag under certainconditions. The driver airbag,seat‐mounted side impact airbags(if equipped), and the roof-railairbags (if equipped) are notaffected by the passengersensing system.

The passenger sensing systemworks with sensors that are partof the right front passenger seatand safety belt. The sensors are

designed to detect the presenceof a properly-seated occupantand determine if the right frontpassenger frontal airbag shouldbe enabled (may inflate) or not.

According to accident statistics,children are safer when properlysecured in a rear seat in the correctchild restraint for their weightand size.

We recommend that children besecured in a rear seat, including:an infant or a child riding in arear-facing child restraint; a childriding in a forward-facing child seat;an older child riding in a boosterseat; and children, who are largeenough, using safety belts.



A label on the sun visor says,“Never put a rear-facing child seatin the front.” This is because the riskto the rear-facing child is so great,if the airbag deploys.

{ WARNING

A child in a rear-facing childrestraint can be seriouslyinjured or killed if the rightfront passenger airbag inflates.This is because the back of therear-facing child restraint wouldbe very close to the inflatingairbag. A child in a forward-facingchild restraint can be seriouslyinjured or killed if the right frontpassenger airbag inflates and thepassenger seat is in a forwardposition.

Even if the passenger sensingsystem has turned off the rightfront passenger frontal airbag, no

WARNING (Continued)

system is fail-safe. No one canguarantee that an airbag willnot deploy under some unusualcircumstance, even though theairbag is turned off.

Secure rear-facing childrestraints in a rear seat, even ifthe airbag is off. If you secure aforward-facing child restraint inthe right front seat, always movethe front passenger seat as farback as it will go. It is better tosecure the child restraint in arear seat.

If the vehicle does not have arear seat that will accommodatea rear-facing child restraint, arear-facing child restraint shouldnot be installed in the vehicle,even if the airbag is off.

The passenger sensing system isdesigned to turn off the right frontpassenger frontal airbag if:. The right front passenger seat is

unoccupied.. The system determines an infant

is present in a child restraint.. A right front passenger takes

his/her weight off of the seat fora period of time.

. Or, if there is a critical problemwith the airbag system or thepassenger sensing system.

When the passenger sensingsystem has turned off the right frontpassenger frontal airbag, the offindicator will light and stay lit toremind you that the airbag is off.See Passenger Airbag StatusIndicator on page 5‑23.



The passenger sensing system isdesigned to turn on (may inflate)the right front passenger frontalairbag anytime the system sensesthat a person of adult size issitting properly in the right frontpassenger seat.

When the passenger sensingsystem has allowed the airbag to beenabled, the on indicator will lightand stay lit to remind you that theairbag is active.

For some children, includingchildren in child restraints, and forvery small adults, the passengersensing system may or may notturn off the right front passengerfrontal airbag, depending upon theperson's seating posture and body

build. Everyone in your vehiclewho has outgrown child restraintsshould wear a safety beltproperly—whether or not thereis an airbag for that person.

{ WARNING

If the airbag readiness light evercomes on and stays on, it meansthat something may be wrongwith the airbag system. To helpavoid injury to yourself or others,have the vehicle serviced rightaway. See Airbag ReadinessLight on page 5‑20 for moreinformation, including importantsafety information.

If the On Indicator is Lit for aChild Restraint

If a child restraint has been installedand the on indicator is lit:

1. Turn the vehicle off.

2. Remove the child restraint fromthe vehicle.

3. Remove any additional itemsfrom the seat such as blankets,cushions, seat covers, seatheaters, or seat massagers.

4. Reinstall the child restraintfollowing the directionsprovided by the child restraintmanufacturer and refer toSecuring Child Restraints(Rear Seat Position) onpage 3‑66 or Securing ChildRestraints (Right Front SeatPosition) on page 3‑69 orSecuring Child Restraints(Center Front Seat Position) onpage 3‑78.



5. If, after reinstalling the childrestraint and restarting thevehicle, the on indicator isstill lit, turn the vehicle off.Then slightly recline the vehicleseatback and adjust the seatcushion, if adjustable, to makesure that the vehicle seatback isnot pushing the child restraintinto the seat cushion.

Also make sure the childrestraint is not trapped underthe vehicle head restraint.If this happens, adjust thehead restraint. See HeadRestraints on page 3‑2.

6. Restart the vehicle.

The passenger sensing systemmay or may not turn off theairbag for a child in a childrestraint depending upon thechild’s seating posture andbody build. It is better to securethe child restraint in a rear seat.

If the Off Indicator is Lit for anAdult-Size Occupant

If a person of adult-size is sittingin the right front passenger seat,but the off indicator is lit, it could bebecause that person is not sittingproperly in the seat. If this happens,

use the following steps to allow thesystem to detect that person andenable the right front passengerfrontal airbag:

1. Turn the vehicle off.

2. Remove any additional materialfrom the seat, such as blankets,cushions, seat covers, seatheaters, or seat massagers.

3. Place the seatback in the fullyupright position.

4. Have the person sit upright inthe seat, centered on the seatcushion, with legs comfortablyextended.

5. Restart the vehicle and have theperson remain in this position fortwo to three minutes after the onindicator is lit.



Additional Factors AffectingSystem Operation

Safety belts help keep thepassenger in position on theseat during vehicle maneuversand braking, which helps thepassenger sensing systemmaintain the passenger airbagstatus. See “Safety Belts” and“Child Restraints” in the Index foradditional information about theimportance of proper restraint use.

If the shoulder portion of the beltis pulled out all the way, the childrestraint locking feature will beengaged. This may unintentionallycause the passenger sensing

system to turn the airbag off forsome adult size occupants. If thishappens, let the belt go back all theway and start again.

A thick layer of additional material,such as a blanket or cushion,or aftermarket equipment suchas seat covers, seat heaters, andseat massagers can affect howwell the passenger sensing systemoperates. We recommend thatyou not use seat covers or otheraftermarket equipment except whenapproved by GM for your specificvehicle. See Adding Equipment tothe Airbag-Equipped Vehicle onpage 3‑46 for more informationabout modifications that can affecthow the system operates.

The on indicator may be lit ifan object, such as a briefcase,handbag, grocery bag, laptop orother electronic device, is put onan unoccupied seat. If this is notdesired, remove the object fromthe seat.

{ WARNING

Stowing of articles under thepassenger seat or between thepassenger seat cushion andseatback may interfere with theproper operation of the passengersensing system.



Servicing theAirbag-Equipped VehicleAirbags affect how the vehicleshould be serviced. There areparts of the airbag system inseveral places around the vehicle.Your dealer and the service manualhave information about servicingthe vehicle and the airbag system.To purchase a service manual, seeService Publications OrderingInformation on page 13‑15.

{ WARNING

For up to 10 seconds after theignition is turned off and thebattery is disconnected, an airbagcan still inflate during improperservice. You can be injured if youare close to an airbag when itinflates. Avoid yellow connectors.They are probably part of theairbag system. Be sure to followproper service procedures, andmake sure the person performingwork for you is qualified to do so.

Adding Equipment to theAirbag-Equipped VehicleQ: Is there anything I might add

to or change about the vehiclethat could keep the airbagsfrom working properly?

A: Yes. If you add things thatchange your vehicle's frame,bumper system, height, front endor side sheet metal, they maykeep the airbag system fromworking properly. Changing ormoving any parts of the frontseats, safety belts, the airbagsensing and diagnostic module,steering wheel, instrumentpanel, roof-rail airbag modules,ceiling headliner or pillar garnishtrim, overhead console, frontsensors, side impact sensors,or airbag wiring can affect theoperation of the airbag system.



In addition, the vehicle may havea passenger sensing systemfor the right front passenger'sposition, which includes sensorsthat are part of the passenger'sseat. The passenger sensingsystem may not operateproperly if the original seattrim is replaced with non-GMcovers, upholstery or trim,or with GM covers, upholsteryor trim designed for a differentvehicle. Any object, such asan aftermarket seat heateror a comfort enhancing pador device, installed under oron top of the seat fabric, couldalso interfere with the operationof the passenger sensingsystem. This could eitherprevent proper deploymentof the passenger airbag(s) orprevent the passenger sensingsystem from properly turningoff the passenger airbag(s).See Passenger SensingSystem on page 3‑40.

Replacing Airbag SystemParts After a Crash

{ WARNING

A crash can damage theairbag systems in the vehicle.A damaged airbag systemmay not work properly andmay not protect you and yourpassenger(s) in a crash, resultingin serious injury or even death.To help make sure the airbagsystems are working properlyafter a crash, have theminspected and any necessaryreplacements made as soonas possible.



If an airbag inflates, you will needto replace airbag system parts.See your dealer for service.

If the airbag readiness light stays onafter the vehicle is started or comeson when you are driving, the airbagsystem may not work properly.Have the vehicle serviced rightaway. See Airbag Readiness Lighton page 5‑20 for more information.

Child Restraints

Older Children

Older children who have outgrownbooster seats should wear thevehicle safety belts.

The manufacturer's instructions thatcome with the booster seat state theweight and height limitations for thatbooster. Use a booster seat witha lap-shoulder belt until the childpasses the fit test below:. Sit all the way back on the seat.

Do the knees bend at the seatedge? If yes, continue. If no,return to the booster seat.

. Buckle the lap-shoulder belt.Does the shoulder belt rest onthe shoulder? If yes, continue.If no, try using the rear safetybelt comfort guide. See “RearSafety Belt Comfort Guides”under Lap-Shoulder Belt onpage 3‑21 for more information.If the shoulder belt still does notrest on the shoulder, then returnto the booster seat.



. Does the lap belt fit low andsnug on the hips, touching thethighs? If yes, continue. If no,return to the booster seat.

. Can proper safety belt fit bemaintained for the length of thetrip? If yes, continue. If no,return to the booster seat.

Q: What is the proper way towear safety belts?

A: An older child should wear alap-shoulder belt and get theadditional restraint a shoulderbelt can provide. The shoulderbelt should not cross the faceor neck. The lap belt should fitsnugly below the hips, justtouching the top of the thighs.This applies belt force to thechild's pelvic bones in a crash.It should never be worn over theabdomen, which could causesevere or even fatal internalinjuries in a crash.

Also see “Rear Safety Belt ComfortGuides” under Lap-Shoulder Belt onpage 3‑21.

According to accident statistics,children and infants are saferwhen properly restrained in a childrestraint system or infant restraintsystem secured in a rear seatingposition.

In a crash, children who are notbuckled up can strike other peoplewho are buckled up, or can bethrown out of the vehicle. Olderchildren need to use safety beltsproperly.

{ WARNING

Never do this.

Never allow two children to wearthe same safety belt. The safetybelt can not properly spread theimpact forces. In a crash, the twochildren can be crushed togetherand seriously injured. A safetybelt must be used by only oneperson at a time.



{ WARNING

Never do this.

Never allow a child to wear thesafety belt with the shoulder beltbehind their back. A child can beseriously injured by not wearingthe lap-shoulder belt properly.In a crash, the child would not berestrained by the shoulder belt.The child could move too farforward increasing the chance ofhead and neck injury. The childmight also slide under the lapbelt. The belt force would thenbe applied right on the abdomen.That could cause serious or fatalinjuries. The shoulder belt shouldgo over the shoulder and acrossthe chest.

Infants and YoungChildrenEveryone in a vehicle needsprotection! This includes infantsand all other children. Neither thedistance traveled nor the age andsize of the traveler changes theneed, for everyone, to use safetyrestraints. In fact, the law in everystate in the United States and inevery Canadian province sayschildren up to some age must berestrained while in a vehicle.

{ WARNING

Children can be seriously injuredor strangled if a shoulder beltis wrapped around their neckand the safety belt continues totighten. Never leave childrenunattended in a vehicle and neverallow children to play with thesafety belts.

Airbags plus lap‐shoulder beltsoffer protection for adults and olderchildren, but not for young childrenand infants. Neither the vehicle'ssafety belt system nor its airbagsystem is designed for them. Everytime infants and young children ridein vehicles, they should have theprotection provided by appropriatechild restraints.



Children who are not restrainedproperly can strike other people,or can be thrown out of the vehicle.

{ WARNING

Never do this.

Never hold an infant or achild while riding in a vehicle.Due to crash forces, an infantor a child will become so heavyit is not possible to hold it duringa crash. For example, in a crashat only 40 km/h (25 mph), a5.5 kg (12 lb) infant will suddenlybecome a 110 kg (240 lb) force ona person's arms. An infant shouldbe secured in an appropriaterestraint.

{ WARNING

Never do this.

Children who are up against,or very close to, any airbag whenit inflates can be seriously injuredor killed. Never put a rear-facingchild restraint in the right frontseat. Secure a rear-facing childrestraint in a rear seat. It is also

(Continued)

WARNING (Continued)

better to secure a forward-facingchild restraint in a rear seat. If youmust secure a forward-facingchild restraint in the right frontseat, always move the frontpassenger seat as far backas it will go.



Q: What are the different types ofadd-on child restraints?

A: Add-on child restraints, whichare purchased by the vehicleowner, are available in four basictypes. Selection of a particularrestraint should take intoconsideration not only the child'sweight, height, and age but alsowhether or not the restraint willbe compatible with the motorvehicle in which it will be used.

For most basic types of childrestraints, there are manydifferent models available.When purchasing a childrestraint, be sure it is designedto be used in a motor vehicle.If it is, the restraint will have alabel saying that it meets federalmotor vehicle safety standards.

The restraint manufacturer'sinstructions that come with therestraint state the weight and

height limitations for a particularchild restraint. In addition, thereare many kinds of restraintsavailable for children withspecial needs.

{ WARNING

To reduce the risk of neck andhead injury during a crash, infantsneed complete support. This isbecause an infant's neck is notfully developed and its headweighs so much compared withthe rest of its body. In a crash,an infant in a rear-facing childrestraint settles into the restraint,so the crash forces can bedistributed across the strongestpart of an infant's body, the backand shoulders. Infants shouldalways be secured in rear-facingchild restraints.

{ WARNING

A young child's hip bones are stillso small that the vehicle's regularsafety belt may not remain lowon the hip bones, as it should.Instead, it may settle up aroundthe child's abdomen. In a crash,the belt would apply force on abody area that is unprotected byany bony structure. This alonecould cause serious or fatalinjuries. To reduce the risk ofserious or fatal injuries during acrash, young children shouldalways be secured in appropriatechild restraints.



Child Restraint Systems

(A) Rear‐Facing Infant Seat

A rear-facing infant seat (A)provides restraint with the seatingsurface against the back of theinfant.

The harness system holds the infantin place and, in a crash, acts tokeep the infant positioned in therestraint.

(B) Forward-Facing Child Seat

A forward-facing child seat (B)provides restraint for the child'sbody with the harness.

(C) Booster Seats

A booster seat (C) is a child restraintdesigned to improve the fit ofthe vehicle's safety belt system.A booster seat can also help achild to see out the window.



Securing an Add-On ChildRestraint in the Vehicle

{ WARNING

A child can be seriously injuredor killed in a crash if the childrestraint is not properly securedin the vehicle. Secure the childrestraint properly in the vehicleusing the vehicle safety belt orLATCH system, following theinstructions that came with thatchild restraint and the instructionsin this manual.

To help reduce the chance of injury,the child restraint must be securedin the vehicle. Child restraintsystems must be secured in vehicleseats by lap belts or the lap beltportion of a lap-shoulder belt, or by

the LATCH system. See LowerAnchors and Tethers for Children(LATCH System) on page 3‑57 formore information. Children can beendangered in a crash if the childrestraint is not properly secured inthe vehicle.

When securing an add-on childrestraint, refer to the instructionsthat come with the restraint whichmay be on the restraint itself or in abooklet, or both, and to this manual.The child restraint instructionsare important, so if they are notavailable, obtain a replacementcopy from the manufacturer.

Keep in mind that an unsecuredchild restraint can move around in acollision or sudden stop and injurepeople in the vehicle. Be sure toproperly secure any child restraintin the vehicle — even when nochild is in it.

In some areas of the United Statesand Canada, Certified ChildPassenger Safety Technicians(CPSTs) are available to inspectand demonstrate how to correctlyuse and install child restraints.In the U.S., refer to the NationalHighway Traffic SafetyAdministration (NHTSA) websiteto locate the nearest child safetyseat inspection station. For CPSTavailability in Canada, check withTransport Canada or the ProvincialMinistry of Transportation office.

Securing the Child Within theChild Restraint

{ WARNING

A child can be seriously injuredor killed in a crash if the childis not properly secured in thechild restraint. Secure the childproperly following the instructionsthat came with that child restraint.



Where to Put theRestraintAccording to accident statistics,children and infants are saferwhen properly restrained in a childrestraint system or infant restraintsystem secured in a rear seatingposition.

We recommend that children andchild restraints be secured in a rearseat, including: an infant or a childriding in a rear-facing child restraint;a child riding in a forward-facingchild seat; an older child riding in abooster seat; and children, who arelarge enough, using safety belts.

If a child restraint is secured in theright front passenger seat, and thevehicle has a switch in the glovebox to manually turn off the rightfront passenger airbag, see AirbagOn-Off Switch on page 3‑37 andSecuring Child Restraints (RearSeat Position) on page 3‑66 orSecuring Child Restraints (RightFront Seat Position) on page 3‑69or Securing Child Restraints (Center

Front Seat Position) on page 3‑78for more information, includingimportant safety information.

A label on the sun visor says,“Never put a rear-facing child seat inthe front.” This is because the riskto the rear-facing child is so great,if the airbag deploys.

{ WARNING


(Continued)

WARNING (Continued)

Even if the passenger sensingsystem or airbag switchhas turned off the right frontpassenger frontal airbag, nosystem is fail-safe. No one canguarantee that an airbag willnot deploy under some unusualcircumstance, even though it isturned off.




{ WARNING

A child in a child restraint in thecenter front seat can be badlyinjured or killed by the frontalairbags if they inflate. Neversecure a child restraint in thecenter front seat. It is alwaysbetter to secure a child restraintin a rear seat.

Do not use child restraints in thecenter front seat position.

When securing a child restraint ina rear seating position, study theinstructions that came with yourchild restraint to make sure it iscompatible with this vehicle.

Child restraints and booster seatsvary considerably in size, and somemay fit in certain seating positionsbetter than others. Always makesure the child restraint is properlysecured.

Depending on where you placethe child restraint and the size ofthe child restraint, you may notbe able to access adjacent safetybelt assemblies or LATCH anchorsfor additional passengers orchild restraints. Adjacent seatingpositions should not be used if thechild restraint prevents access toor interferes with the routing of thesafety belt.

If the vehicle does not havea rear seat that will accommodatea rear-facing child restraint, arear-facing child restraint shouldnot be installed in the vehicle,even if the airbag is off.

Wherever a child restraint isinstalled, be sure to secure thechild restraint properly.

Keep in mind that an unsecuredchild restraint can move around in acollision or sudden stop and injurepeople in the vehicle. Be sure toproperly secure any child restraintin your vehicle— even when nochild is in it.

Lower Anchors andTethers for Children(LATCH System)The LATCH system holds a childrestraint during driving or in a crash.This system is designed to makeinstallation of a child restraint easier.The LATCH system uses anchors inthe vehicle and attachments on thechild restraint that are made for usewith the LATCH system.

Make sure that a LATCH-compatiblechild restraint is properly installedusing the anchors, or use thevehicle's safety belts to secure therestraint, following the instructionsthat came with that restraint, andalso the instructions in this manual.



When installing a child restraintwith a top tether, you must alsouse either the lower anchors or thesafety belts to properly secure thechild restraint. A child restraint mustnever be installed using only the toptether and anchor.

In order to use the LATCH systemin your vehicle, you need achild restraint that has LATCHattachments. The child restraintmanufacturer will provide youwith instructions on how to use thechild restraint and its attachments.The following explains how toattach a child restraint with theseattachments in your vehicle.

Not all vehicle seating positions orchild restraints have lower anchorsand attachments or top tetheranchors and attachments.

Lower Anchors

Lower anchors (A) are metalbars built into the vehicle.There are two lower anchors foreach LATCH seating position thatwill accommodate a child restraintwith lower attachments (B).

Top Tether Anchor

A top tether (A, C) anchors thetop of the child restraint to thevehicle. A top tether anchor is builtinto the vehicle. The top tetherattachment (B) on the child restraintconnects to the top tether anchor inthe vehicle in order to reduce theforward movement and rotation ofthe child restraint during driving orin a crash.



Your child restraint may havea single tether (A) or a dualtether (C). Either will have asingle attachment (B) to securethe top tether to the anchor.

Some child restraints that havea top tether are designed for usewith or without the top tether beingattached. Others require the toptether always to be attached.In Canada, the law requires thatforward-facing child restraints havea top tether, and that the tetherbe attached. Be sure to read andfollow the instructions for yourchild restraint.

For crew and extended cab models,the top tether anchors are the loopslocated near the top of the seatbackfor each rear seating position.These loops will be used to routethe top tether through, as well as, tosecure the top tether in the vehicle.Be sure to use an anchor (loop)located on the same side of thevehicle as the seating positionwhere the child restraint will beplaced.

Be sure to read the instructionsfollowing to properly install a childrestraint using these loops.

Do not secure a child restraint in aposition without a top tether anchorif a national or local law requiresthat the top tether be attached, or ifthe instructions that come with thechild restraint say that the top tethermust be attached.

According to accident statistics,children and infants are saferwhen properly restrained in a childrestraint system or infant restraintsystem secured in a rear seatingposition. See Where to Put theRestraint on page 3‑56 foradditional information.



Securing a Child RestraintDesigned for the LATCHSystem

{ WARNING

If a LATCH-type child restraint isnot attached to anchors, the childrestraint will not be able to protectthe child correctly. In a crash, thechild could be seriously injuredor killed. Install a LATCH-typechild restraint properly using theanchors, or use the vehicle safetybelts to secure the restraint,following the instructions thatcame with the child restraint andthe instructions in this manual.

{ WARNING

Do not attach more than onechild restraint to a single anchor,except for the center top tetheranchors in the crew and extendedcabs. Attaching more than onechild restraint to a single anchorcould cause the anchor orattachment to come loose or evenbreak during a crash. A child orothers could be injured. To reducethe risk of serious or fatal injuriesduring a crash, attach only onechild restraint per anchor.

{ WARNING

Children can be seriously injuredor strangled if a shoulder beltis wrapped around their neckand the safety belt continues totighten. Buckle any unused safetybelts behind the child restraintso children cannot reach them.Pull the shoulder belt all the wayout of the retractor to set the lock,if the vehicle has one, after thechild restraint has been installed.

Notice: Do not let the LATCHattachments rub against thevehicle’s safety belts. This maydamage these parts. If necessary,move buckled safety belts toavoid rubbing the LATCHattachments.



Do not fold the empty rearseat with a safety belt buckled.This could damage the safetybelt or the seat. Unbuckle andreturn the safety belt to itsstowed position, before foldingthe seat.

Replacing LATCH SystemParts After a Crash

{ WARNING

A crash can damage theLATCH system in the vehicle.A damaged LATCH system maynot properly secure the childrestraint, resulting in seriousinjury or even death in a crash.To help make sure the LATCHsystem is working properly aftera crash, see your dealer to havethe system inspected and anynecessary replacements madeas soon as possible.

If the vehicle has the LATCH systemand it was being used during acrash, new LATCH system partsmay be needed.

New parts and repairs may benecessary even if the LATCHsystem was not being used atthe time of the crash.

Securing Child Restraints(Rear Seat Position)When securing a child restraint ina rear seating position, study theinstructions that came with thechild restraint to make sure it iscompatible with this vehicle.

If the child restraint has theLATCH system, see Lower Anchorsand Tethers for Children (LATCHSystem) on page 3‑57 for how andwhere to install the child restraintusing LATCH. If a child restraintis secured in the vehicle using asafety belt and it uses a top tether,see Lower Anchors and Tethersfor Children (LATCH System) onpage 3‑57 for top tether anchorlocations.

Do not secure a child seat in aposition without a top tether anchorif a national or local law requiresthat the top tether be anchored, or ifthe instructions that come with thechild restraint say that the top strapmust be anchored.



In Canada, the law requires thatforward-facing child restraints havea top tether, and that the tether beattached.

If the child restraint does not havethe LATCH system, you will beusing the safety belt to securethe child restraint in this position.Be sure to follow the instructionsthat came with the child restraint.Secure the child in the child restraintwhen and as the instructions say.

If more than one child restraintneeds to be installed in the rearseat, be sure to read Where toPut the Restraint on page 3‑56.

1. Put the child restraint onthe seat.

2. Pick up the latch plate, and runthe lap and shoulder portions ofthe vehicle's safety belt throughor around the restraint. The childrestraint instructions will showyou how.

For crew cab second rowseatings positions, tilt the latchplate to adjust the belt if needed.


Position the release button onthe buckle so that the safety beltcould be quickly unbuckled ifnecessary.



4. Pull the shoulder belt all the wayout of the retractor to set thelock. When the retractor lock isset, the belt can be tightened butnot pulled out of the retractor.

5. To tighten the belt, push downon the child restraint, pull theshoulder portion of the belt totighten the lap portion of the belt,and feed the shoulder belt backinto the retractor. When installinga forward-facing child restraint,it may be helpful to use yourknee to push down on the childrestraint as you tighten the belt.

Try to pull the belt out ofthe retractor to make surethe retractor is locked. If theretractor is not locked, repeatSteps 4 and 5.

6. If the child restraint has a toptether, follow the child restraintmanufacturer's instructionsregarding the use of the toptether. See Lower Anchors andTethers for Children (LATCHSystem) on page 3‑57 for moreinformation.

7. Before placing a child in thechild restraint, make sureit is securely held in place.To check, grasp the childrestraint at the safety beltpath and attempt to move itside‐to‐side and back‐and‐forth.When the child restraint isproperly installed, there shouldbe no more than 2.5 cm (1 in)of movement.

To remove the child restraint,unbuckle the vehicle safety belt andlet it return to the stowed position.If the top tether is attached to a toptether anchor, disconnect it.

CompassThe vehicle may have a compass inthe Driver Information Center (DIC).

Compass Zone

The zone is set to zone eight uponleaving the factory. Your dealerwill set the correct zone for yourlocation.

Under certain circumstances,such as during a long-distance,cross-country trip or moving toa new state or province, it willbe necessary to compensate forcompass variance by resetting thezone through the DIC if the zoneis not set correctly.

Compass variance is the differencebetween the earth's magnetic northand true geographic north. If thecompass is not set to the zonewhere you live, the compass maygive false readings. The compassmust be set to the variance zone inwhich the vehicle is traveling.

To adjust for compass variance, usethe following procedure:

Compass Variance (Zone)Procedure

1. Do not set the compass zonewhen the vehicle is moving.Only set it when the vehicleis in P (Park).

Press the vehicle informationbutton until PRESS V TOCHANGE COMPASS ZONEdisplays. Or, if the vehicle doesnot have DIC buttons, press thetrip odometer reset stem untilCHANGE COMPASS ZONEdisplays.



2. Find the vehicle's currentlocation and variance zonenumber on the map.

Zones 1 through 15 areavailable.

3. Press the set/reset button toscroll through and select theappropriate variance zone.

4. Press the trip/fuel buttonuntil the vehicle heading,for example, N for North,is displayed in the DIC.Or, if the vehicle does nothave DIC buttons, press andhold the trip odometer resetstem for two seconds to selectthe next available variancezone. Repeat this step untilthe appropriate variancezone is displayed.

5. If calibration is necessary,calibrate the compass.See “Compass CalibrationProcedure” following.

Compass Calibration

The compass can be manuallycalibrated. Only calibrate thecompass in a magnetically cleanand safe location, such as anopen parking lot, where driving thevehicle in circles is not a danger.

It is suggested to calibrate awayfrom tall buildings, utility wires,manhole covers, or other industrialstructures, if possible.

If CAL should ever appear in theDIC display, the compass should becalibrated.

If the DIC display does not show aheading, for example, N for North,or the heading does not changeafter making turns, there may bea strong magnetic field interferingwith the compass. Such interferencemay be caused by a magnetic CBor cell phone antenna mount, amagnetic emergency light, magneticnote pad holder, or any othermagnetic item. Turn off the vehicle,move the magnetic item, then turnon the vehicle and calibrate thecompass.



To calibrate the compass, use thefollowing procedure:

Compass Calibration Procedure

1. Before calibrating the compass,make sure the compass zoneis set to the variance zone inwhich the vehicle is located.See “Compass Variance (Zone)Procedure” earlier in thissection.

Do not operate any switchessuch as window, sunroof,climate controls, or seats duringthe calibration procedure.

2. Press the vehicle informationbutton until PRESS V TOCALIBRATE COMPASSdisplays. Or, if the vehicledoes not have DIC buttons,press the trip odometerreset stem until CALIBRATECOMPASS displays.

3. Press the set/reset button tostart the compass calibration.Or, if the vehicle does not haveDIC buttons, press and holdthe trip odometer reset stemfor two seconds to start thecompass calibration.

4. The DIC will displayCALIBRATING: DRIVE INCIRCLES. Drive the vehiclein tight circles at less than8 km/h (5 mph) to complete thecalibration. The DIC will displayCALIBRATION COMPLETEfor a few seconds when thecalibration is complete. The DICdisplay will then return to theprevious menu.

Charging System Light

This light comes on briefly whenthe ignition key is turned to START,but the engine is not running, as acheck to show it is working.

If it does not, have the vehicleserviced by your dealer.

The light should go out oncethe engine starts. If it stays on,or comes on while driving, therecould be a problem with thecharging system. A charging systemmessage in the Driver InformationCenter (DIC) can also appear.See Battery Voltage and ChargingMessages on page 5‑41 for moreinformation. This light could indicatethat there are problems with agenerator drive belt, or that thereis an electrical problem. Have itchecked right away. If the vehiclemust be driven a short distance withthe light on, turn off accessories,such as the radio and airconditioner.




MalfunctionIndicator LampA computer system called OBD II(On-Board Diagnostics-SecondGeneration) monitors operation ofthe fuel, ignition, and emissioncontrol systems. It ensures thatemissions are at acceptable levelsfor the life of the vehicle, helping toproduce a cleaner environment.

This light should come on when theignition is on, but the engine is notrunning, as a check to show it isworking. If it does not, have thevehicle serviced by your dealer.

If the Malfunction Indicator Lampcomes on and stays on while theengine is running, this indicatesthat there is an OBD II problemand service is required.

Malfunctions often are indicated bythe system before any problem isapparent. Being aware of the lightcan prevent more serious damageto the vehicle. This system assiststhe service technician in correctlydiagnosing any malfunction.

Notice: If the vehicle iscontinually driven with this lighton, after a while, the emissioncontrols might not work as well,the vehicle fuel economy mightnot be as good, and the enginemight not run as smoothly.This could lead to costly repairsthat might not be covered by thevehicle warranty.

Notice: Modifications madeto the engine, transmission,exhaust, intake, or fuel systemof the vehicle or the replacementof the original tires withother than those of the sameTire Performance Criteria (TPC)can affect the vehicle's emissioncontrols and can cause this lightto come on. Modifications tothese systems could lead tocostly repairs not covered bythe vehicle warranty. This couldalso result in a failure topass a required EmissionInspection/Maintenancetest. See Accessories andModifications on page 10‑3.

This light comes on during amalfunction in one of two ways:

Light Flashing: A misfire conditionhas been detected. A misfireincreases vehicle emissions andcould damage the emission controlsystem on the vehicle. Diagnosisand service might be required.



To prevent more serious damage tothe vehicle:. Reduce vehicle speed.. Avoid hard accelerations.. Avoid steep uphill grades.. If towing a trailer, reduce the

amount of cargo being hauledas soon as it is possible.

If the light continues to flash, whenit is safe to do so, stop the vehicle.Find a safe place to park thevehicle. Turn the vehicle off, wait atleast 10 seconds, and restart theengine. If the light is still flashing,follow the previous steps and seeyour dealer for service as soon aspossible.

Light On Steady: An emissioncontrol system malfunction hasbeen detected on the vehicle.Diagnosis and service might berequired.

The following may correct anemissions system malfunction:. Make sure the fuel cap is

fully installed. See Fillingthe Tank on page 9‑88.The diagnostic system candetermine if the fuel cap hasbeen left off or improperlyinstalled. A loose or missing fuelcap allows fuel to evaporate intothe atmosphere. A few drivingtrips with the cap properlyinstalled should turn the light off.

. Make sure the electrical systemis not wet. The system couldbe wet if the vehicle was driventhrough a deep puddle of water.The condition is usuallycorrected when the electricalsystem dries out. A few drivingtrips should turn the light off.

. Make sure to fuel the vehiclewith quality fuel. Poor fuel qualitycauses the engine not to run asefficiently as designed and cancause: stalling after start-up,stalling when the vehicle ischanged into gear, misfiring,hesitation on acceleration,or stumbling on acceleration.These conditions might go awayonce the engine is warmed up.

If one or more of theseconditions occurs, change thefuel brand used. It will require atleast one full tank of the properfuel to turn the light off.

See Recommended Fuel onpage 9‑84.

If none of the above have madethe light turn off, your dealer cancheck the vehicle. The dealerhas the proper test equipmentand diagnostic tools to fix anymechanical or electrical problemsthat might have developed.



Emissions Inspection andMaintenance Programs

Some state/provincial andlocal governments may haveprograms to inspect the on-vehicleemission control equipment.For the inspection, the emissionsystem test equipment is connectedto the vehicle’s Data LinkConnector (DLC).

The DLC is under the instrumentpanel to the left of the steeringwheel. See your dealer if assistanceis needed.

The vehicle may not passinspection if:. The malfunction indicator lamp is

on with the engine running, or ifthe light does not come on whenthe ignition is turned to ON/RUNwhile the engine is off.

. The critical emission controlsystems have not beencompletely diagnosed bythe system. This can happenif the battery has recentlybeen replaced or if the batteryhas run down. The diagnosticsystem evaluates criticalemission control systems duringnormal driving. This can takeseveral days of routine driving.If this has been done and thevehicle still does not pass theinspection, your dealer canprepare the vehicle forinspection.

Universal Remote SystemProgramming

Vehicles with the Universal RemoteSystem will have these buttonslocated in the headliner.

This system provides a way toreplace up to three remote controltransmitters used to activatedevices such as garage dooropeners, security systems, andhome automation devices.

Do not use this system with anygarage door opener that does nothave the stop and reverse feature.This includes any garage dooropener model manufactured beforeApril 1, 1982.

Read the instructions completelybefore attempting to program thetransmitter. Because of the stepsinvolved, it may be helpful tohave another person assist withprogramming the transmitter.



Be sure to keep the originalremote control transmitter foruse in other vehicles, as well asfor future programming. Only theoriginal remote control transmitteris needed for Fixed Codeprogramming. The programmedbuttons should be erased when thevehicle is sold or the lease ends.See “Erasing Universal HomeRemote Buttons” in this section.

Park the vehicle outside of thegarage when programming a garagedoor. Be sure that people andobjects are clear of the garage dooror gate that is being programmed.

Exit LightingThe interior lamps come on whenthe key is removed from the ignition.They turn off automatically in20 seconds. The lights do not comeon if the dome override button ispressed in.

Battery LoadManagementThe vehicle has Electric PowerManagement (EPM) that estimatesthe battery's temperature and stateof charge. It then adjusts the voltagefor best performance and extendedlife of the battery.

When the battery's state of chargeis low, the voltage is raised slightlyto quickly bring the charge back up.When the state of charge is high,the voltage is lowered slightly toprevent overcharging. If the vehiclehas a voltmeter gauge or a voltagedisplay on the Driver InformationCenter (DIC), you may see thevoltage move up or down. This isnormal. If there is a problem, analert will be displayed.


6-10 Lighting

The battery can be discharged atidle if the electrical loads are veryhigh. This is true for all vehicles.This is because the generator(alternator) may not be spinningfast enough at idle to produce allthe power that is needed for veryhigh electrical loads.

A high electrical load occurs whenseveral of the following are on,such as: headlamps, high beams,fog lamps, rear window defogger,climate control fan at high speed,heated seats, engine cooling fans,trailer loads, and loads plugged intoaccessory power outlets.

EPM works to prevent excessivedischarge of the battery. It does thisby balancing the generator's outputand the vehicle's electrical needs.It can increase engine idle speedto generate more power, wheneverneeded. It can temporarily reducethe power demands of someaccessories.

Normally, these actions occurin steps or levels, without beingnoticeable. In rare cases at thehighest levels of corrective action,this action may be noticeable to thedriver. If so, a Driver InformationCenter (DIC) message might bedisplayed, such as BATTERYSAVER ACTIVE, BATTERYVOLTAGE LOW, or LOW BATTERY.If one of these messages displays,it is recommended that the driverreduce the electrical loads as muchas possible. See Driver InformationCenter (DIC) on page 5‑33.

Battery Power ProtectionThis feature shuts off the dome andreading lamps, if they are left onfor more than 10 minutes after theignition is turned off. The cargolamp shuts off after 20 minutes.This prevents the battery fromrunning down.

Radio ReceptionFrequency interference andstatic can occur during normalradio reception if items suchas cell phone chargers, vehicleconvenience accessories, andexternal electronic devices areplugged into the accessory poweroutlet. If there is interference orstatic, unplug the item from theaccessory power outlet.

AM

The range for most AM stations isgreater than for FM, especially atnight. The longer range can causestation frequencies to interferewith each other. For better radioreception, most AM radio stationsboost the power levels during theday, and then reduce these levelsduring the night. Static can alsooccur when things like storms andpower lines interfere with radioreception. When this happens, tryreducing the treble on the radio.

FM Stereo

FM signals only reach about16 to 65 km (10 to 40 miles).Although the radio has a built-inelectronic circuit that automaticallyworks to reduce interference, somestatic can occur, especially aroundtall buildings or hills, causing thesound to fade in and out.

XM™ Satellite Radio Service

XM Satellite Radio Service givesdigital radio reception from coastto coast in the 48 contiguousUnited States, and in Canada.Just as with FM, tall buildings orhills can interfere with satellite radiosignals, causing the sound to fadein and out. In addition, travelingor standing under heavy foliage,bridges, garages, or tunnels maycause loss of the XM signal for aperiod of time.

Cellular Phone Usage

Cellular phone usage may causeinterference with the vehicle'sradio. This interference may occurwhen making or receiving phonecalls, charging the phone's battery,or simply having the phone on.This interference causes anincreased level of static whilelistening to the radio. If static isreceived while listening to theradio, unplug the cellular phoneand turn it off.



Fixed Mast AntennaThe fixed mast antenna canwithstand most car washes withoutbeing damaged as long as it issecurely attached to the base.If the mast becomes slightly bent,straighten it out by hand. If themast is badly bent, replace it.

Occasionally check to make surethe antenna is tightened to its base.If tightening is required, tightenby hand until fully seated plusone quarter turn.

Satellite Radio AntennaThe XM Satellite Radio antennais located on the roof of thevehicle. Keep the antenna clearof obstructions for clear radioreception.

If the vehicle has a sunroof, theperformance of the XM system(if equipped) may be affectedif the sunroof is open.

The rear window defogger onlyworks when the ignition is inON/RUN. The rear windowdefogger stays on for approximately10 minutes after the button ispressed, unless the ignition isturned to ACC/ACCESSORY orLOCK/OFF. The defogger canalso be turned off by turning offthe engine.

Notice: Do not use anythingsharp on the inside of the rearwindow. If you do, you could cutor damage the warming grid, andthe repairs would not be coveredby the vehicle warranty. Do notattach a temporary vehiclelicense, tape, a decal, or anythingsimilar to the defogger grid.



Climate Control Systems (with Heater Only)With this system the heating and ventilation can be controlled.

A. Fan Control



Temperature Control: Turnclockwise or counterclockwiseto increase or decrease thetemperature inside the vehicle.

9 (Fan Control): Turn clockwiseor counterclockwise to increase ordecrease the fan speed. Turn theknob all the way counterclockwiseto turn the front system off.

Air Delivery Mode Control: Turnclockwise or counterclockwiseto increase or decrease thetemperature inside the vehicle.The knob can be positionedbetween two modes to select acombination of those modes.

Select from the following:


) (Bi-Level): Air is dividedbetween the instrument panel andfloor outlets.



6 (Floor): Air is directed to thefloor outlets, with some air directedto the windshield, side window, andsecond row floor outlets. In thismode, the system automaticallyselects outside air.

- (Defog): This mode clears thewindows of fog or moisture. Air isdirected to the windshield, flooroutlets, and side window vents.

0 (Defrost): This moderemoves fog or frost from thewindshield more quickly. Air isdirected to the windshield andthe side window vents, with someair directed to the floor vents.The system automatically forcesoutside air into the vehicle.

Do not drive the vehicle until all thewindows are clear.

Dual Automatic Climate Control SystemThe heating, cooling, and ventilation in the vehicle can be controlled withthis system. The vehicle also has a flow-through ventilation systemdescribed later in this section.

This direction can be changedby pressing the mode button.Recirculation can be selected onceyou have selected vent or bi-levelmode. The temperature can also beadjusted using either temperaturebutton. If the air delivery mode ortemperature settings are adjustedwith the system off, the displayilluminates briefly to show thesettings and then returns to off.The system can be turned backon by pressing either O, D, C,#,the defrost or the AUTO button.

Driver and Passenger SideTemperature Controls

The driver and passenger sidetemperature buttons are used toadjust the temperature of the aircoming through the system onthe driver or passenger side ofthe vehicle. The temperature canbe adjusted even if the system isturned off. This is possible sinceoutside air always flows throughthe system as the vehicle ismoving forward unless it isset to recirculation mode.See “Recirculation” later inthis section.

Press the + or − buttons to increaseor decrease the cabin temperature.The driver side or passenger side

temperature display shows thetemperature setting increasing ordecreasing.

The passenger temperaturesetting can be set to match thedriver temperature setting bypressing the PASS button andturning off the PASS indicator.When the passenger temperaturesetting is set different than the driversetting, the indicator on the PASSbutton illuminates and both thedriver side and passenger sidetemperature displays are shown.

When in defrost mode thepassenger temperature settingcannot be changed.



Automatic Operation

AUTO (Automatic): Whenautomatic operation is active,the system controls the insidetemperature, the air delivery,and the fan speed.

Use the steps below to place theentire system in automatic mode:

1. Press the AUTO button.

When AUTO is selected, thedisplay changes to show thecurrent temperature(s) andAUTO is lit on the display.The current air delivery modeand fan speed are alsodisplayed for about five seconds.

When AUTO is selected, the airconditioning operation and airinlet are automatically controlled.The air conditioning compressormay run when the outsidetemperature is above freezing.

The air inlet will normally be setto outside air. If it is hot outside,the air inlet may automaticallyswitch to the recirculate mode tohelp quickly cool down the airinside the vehicle. The lighton the button comes on inrecirculation.

2. Set the driver and passengertemperature.

To find your comfort setting, startwith a 23°C (74°F) temperaturesetting and allow about20 minutes for the system toregulate. Use the driver orpassenger temperature buttonsto adjust the temperature settingas necessary. If a temperaturesetting of 15°C (60°F) is chosen,the system remains at themaximum cooling setting.If a temperature setting of32°C (90°F) is chosen, the

system remains at the maximumheat setting. Choosing eithermaximum setting will not causethe vehicle to heat or cool anyfaster.

Do not cover the solar sensorlocated on the top of the instrumentpanel near the windshield.This sensor regulates airtemperature based on sun load.For more information on the solarsensor, see “Sensors” later in thissection.

To avoid blowing cold air in coldweather, the system delaysturning the fan on until warm airis available. The length of delaydepends on the engine coolanttemperature. Pressing the fanswitch overrides this delay andchanges the fan to a selectedspeed.



Manual Operation

D C (Fan Control): Press thesebuttons to increase or decrease thefan speed.

Pressing either fan button while inautomatic control places the fanunder manual control. The fansetting remains displayed andthe AUTO light turns off. The airdelivery mode remains underautomatic control.

H G (Air Delivery Mode Control):Press these buttons to change thedirection of the airflow in the vehicle.Repeatedly press either button untilthe desired mode appears on thedisplay.

Pressing either mode button whilethe system is off changes the airdelivery mode without turning thesystem on.

Pressing either mode button while inautomatic control places the modeunder manual control. The airdelivery mode setting displays andthe AUTO light turns off. The fanremains under automatic control.


) (Bi-Level): Air is dividedbetween the instrument panel andfloor outlets. Some air is directedtoward the windshield and sidewindow outlets.

6 (Floor): Air is directed to thefloor outlets, with some to thewindshield, side window outlets,and second row floor outlets. In thismode, the system automaticallyselects outside air.

- (Defog): This mode clearsthe windows of fog or moisture.Air is directed to the windshield,floor outlets, and side window vents.In this mode, the system turnsoff recirculation and runs the airconditioning compressor unlessthe outside temperature is close tofreezing. The recirculation modecannot be selected while in thedefrost mode.

0 (Defrost): This mode removesfog or frost from the windshieldmore quickly. Air is directed to thewindshield and side window vents,with some directed to the floorvents. In this mode, the systemautomatically forces outside airinto the vehicle and runs the airconditioning compressor unlessthe outside temperature is close tofreezing. The recirculation modecannot be selected while in thedefrost mode.



The passenger temperaturecontrol cannot be activated while indefrost mode. If the PASS button ispressed, the button indicator flashesthree times and will not work. If thepassenger temperature buttons areadjusted, the driver temperatureindicator changes. The passengertemperature will not be displayed.

If vent, bi-level, or floor mode isselected again, the climate controlsystem displays the previoustemperature settings.

Do not drive the vehicle until allwindows are clear.

# (Air Conditioning): Pressto turn the air conditioning (A/C)compressor on and off. An indicatorlight comes on to show that the airconditioning is on.

If this button is pressed whenthe air conditioning compressoris unavailable due to outsideconditions, the indicator flashesthree times and then turns off.If the air conditioning is on and theoutside temperature drops below atemperature which is too cool for airconditioning to be effective, the airconditioning light turns off to showthat the air conditioning mode hasbeen canceled.

On hot days, open the windows longenough to let hot inside air escape.This helps to reduce the time ittakes for the vehicle to cool down.It also helps the system to operatemore efficiently.

The air conditioning systemremoves moisture from the air, soa small amount of water mightdrip under the vehicle while idlingor after turning off the engine.This is normal.

@ (Recirculation): Pressto turn the recirculation mode on.An indicator light comes on to showthat recirculation is on.

This mode recirculates and helpsto quickly cool the air inside thevehicle. It can be used to helpprevent outside air and odorsfrom entering the vehicle.

The recirculation mode cannotbe used with floor, defog, ordefrost modes. If recirculation isselected with one of those modes,the indicator light flashes threetimes and then turns off. The airconditioning compressor also comeson when this mode is activated.While in recirculation mode, thewindows may fog when the weatheris cold and damp. To clear the fog,select either the defog or defrostmode and increase the fan speed.



The recirculation mode can beturned off by pressing the outsideair button, or by turning off theignition.

; (Outside Air): Press to turn theoutside air mode on. An indicatorlight on the button comes on toshow that outside is on. Whenselected, air from outside thevehicle circulates throughout thevehicle. The recirculation modecannot be used with the outsideair mode.

Rear Window Defogger

The rear window defogger uses awarming grid to remove fog from therear window.

< (Rear Window Defogger):For vehicles with this feature,press to turn the defogger on or off.It automatically turns off severalminutes after it has been activated.

The defogger can also be turned offby turning the engine off. Do notdrive the vehicle until all windowsare clear.

Notice: Do not use a razor bladeor sharp object to clear the insiderear window. Do not adhereanything to the defogger gridlines in the rear glass. Theseactions may damage the reardefogger. Repairs would not becovered by your warranty.

Heated Mirror: For vehicles withheated outside rearview mirrors, themirrors heat to help clear fog or frostfrom the surface of the mirror whenthe rear window defog button ispressed. See Power Mirrors onpage 2‑16.

Sensors

The solar sensor, located in thedefrost grille in the middle of theinstrument panel, monitors the solarheat. Do not cover the solar sensoror the system will not work properly.



The interior temperature sensor,located in the headliner, measuresthe temperature of the air inside thevehicle.

There is also an exteriortemperature sensor locatedbehind the front grille. This sensorreads the outside air temperatureand helps maintain the temperatureinside the vehicle. Any cover onthe front of the vehicle could causea false reading in the displayedtemperature.

The climate control system usesthe information from these sensorsto maintain comfort settings byadjusting the outlet temperature, fanspeed, and the air delivery mode.The system may also supply coolerair to the side of the vehicle facingthe sun. The recirculation mode willalso be used as needed to maintaincool outlet temperatures.

Air VentsUse the air outlets located in thecenter and on the side of theinstrument panel to direct theairflow. Use the thumbwheelsnear the air outlets to open orclose off the airflow.

Operation Tips. Clear away any ice, snow,

or leaves from air inlets at thebase of the windshield that couldblock the flow of air into thevehicle.

. Keep the path under the frontseats clear of objects to helpcirculate the air inside of thevehicle more effectively.

. Use of non‐GM approved hooddeflectors can adversely affectthe performance of the system.Check with your dealer beforeadding equipment to the outsideof the vehicle.

Driving Information

Defensive DrivingDefensive driving means “alwaysexpect the unexpected.” The firststep in driving defensively is to wearthe safety belt. See Safety Belts onpage 3‑11.

{ WARNING

Assume that other road users(pedestrians, bicyclists, and otherdrivers) are going to be carelessand make mistakes. Anticipatewhat they might do and be ready.In addition:

. Allow enough followingdistance between you andthe driver in front of you.

. Focus on the task of driving.

(Continued)

WARNING (Continued)

Driver distraction can causecollisions resulting in injury orpossible death. These simpledefensive driving techniquescould save your life.

Drunk Driving

{ WARNING

Drinking and then driving isvery dangerous. Your reflexes,perceptions, attentiveness, andjudgment can be affected byeven a small amount of alcohol.You can have a serious — oreven fatal — collision if you driveafter drinking. Do not drink anddrive or ride with a driver who hasbeen drinking. Ride home in acab; or if you are with a group,designate a driver who will notdrink.



Death and injury associated withdrinking and driving is a globaltragedy.

Alcohol affects four things thatanyone needs to drive a vehicle:judgment, muscular coordination,vision, and attentiveness.

Police records show thatalmost 40 percent of all motorvehicle-related deaths involvealcohol. In most cases, thesedeaths are the result of someonewho was drinking and driving.In recent years, more than17,000 annual motor vehicle-relateddeaths have been associated withthe use of alcohol, with about250,000 people injured.

For persons under 21, it is againstthe law in every U.S. state to drinkalcohol. There are good medical,psychological, and developmentalreasons for these laws.

The obvious way to eliminate theleading highway safety problem isfor people never to drink alcoholand then drive.

Medical research shows thatalcohol in a person's systemcan make crash injuries worse,especially injuries to the brain,spinal cord, or heart. This meansthat when anyone who has beendrinking — driver or passenger — isin a crash, that person's chance ofbeing killed or permanently disabledis higher than if the person had notbeen drinking.

Control of a VehicleThe following three systemshelp to control the vehicle whiledriving — brakes, steering, andaccelerator. At times, as whendriving on snow or ice, it is easy toask more of those control systemsthan the tires and road can provide.Meaning, you can lose control of thevehicle. See StabiliTrak® System onpage 9‑70.

Adding non‐dealer accessoriescan affect vehicle performance.See Accessories and Modificationson page 10‑3.

BrakingSee Brake System Warning Light onpage 5‑27.

Braking action involves perceptiontime and reaction time. Decidingto push the brake pedal isperception time. Actually doingit is reaction time.

Average reaction time is aboutthree‐fourths of a second. But thatis only an average. It might be lesswith one driver and as long as twoor three seconds or more withanother. Age, physical condition,alertness, coordination, andeyesight all play a part. So doalcohol, drugs, and frustration. Buteven in three‐fourths of a second,a vehicle moving at 100 km/h(60 mph) travels 20 m (66 ft).That could be a lot of distance inan emergency, so keeping enoughspace between the vehicle andothers is important.



And, of course, actual stoppingdistances vary greatly with thesurface of the road, whether it ispavement or gravel; the conditionof the road, whether it is wet, dry,or icy; tire tread; the condition of thebrakes; the weight of the vehicle;and the amount of brake forceapplied.

Avoid needless heavybraking. Some people drive inspurts — heavy accelerationfollowed by heavy braking — ratherthan keeping pace with traffic.This is a mistake. The brakesmight not have time to cool betweenhard stops. The brakes will wearout much faster with a lot of heavybraking. Keeping pace with thetraffic and allowing realistic followingdistances eliminates a lot ofunnecessary braking. That meansbetter braking and longer brake life.

If the engine ever stops while thevehicle is being driven, brakenormally but do not pump the

brakes. If the brakes are pumped,the pedal could get harder to pushdown. If the engine stops, there willstill be some power brake assist butit will be used when the brake isapplied. Once the power assist isused up, it can take longer to stopand the brake pedal will be harderto push.

Adding non‐dealer accessoriescan affect vehicle performance.See Accessories and Modificationson page 10‑3.

Steering

Power Steering


If power steering assist is lostbecause the engine stops or thepower steering system is notfunctioning, the vehicle can besteered but it will take more effort.

Steering Tips

It is important to take curves at areasonable speed.

Traction in a curve depends on thecondition of the tires and the roadsurface, the angle at which thecurve is banked, and vehicle speed.While in a curve, speed is the onefactor that can be controlled.

If there is a need to reduce speed,do it before entering the curve, whilethe front wheels are straight.

Try to adjust the speed so you candrive through the curve. Maintain areasonable, steady speed. Wait toaccelerate until out of the curve,and then accelerate gently intothe straightaway.



Steering in Emergencies

There are times when steeringcan be more effective than braking.For example, you come over a hilland find a truck stopped in yourlane, or a car suddenly pulls outfrom nowhere, or a child darts outfrom between parked cars and stopsright in front of you. These problemscan be avoided by braking— if youcan stop in time. But sometimes youcannot stop in time because thereis no room. That is the time forevasive action— steering aroundthe problem.

The vehicle can perform verywell in emergencies like these.First, apply the brakes. See Brakingon page 9‑3. It is better to removeas much speed as possible froma collision. Then steer aroundthe problem, to the left or rightdepending on the space available.

An emergency like this requiresclose attention and a quick decision.If holding the steering wheel atthe recommended 9 and 3 o'clockpositions, it can be turned a full180 degrees very quickly withoutremoving either hand. But you haveto act fast, steer quickly, and just asquickly straighten the wheel onceyou have avoided the object.

The fact that such emergencysituations are always possible is agood reason to practice defensivedriving at all times and wear safetybelts properly.

Off-Road RecoveryThe vehicle's right wheels can dropoff the edge of a road onto theshoulder while driving.

If the level of the shoulder isonly slightly below the pavement,recovery should be fairly easy. Easeoff the accelerator and then, if thereis nothing in the way, steer so thatthe vehicle straddles the edge ofthe pavement. Turn the steeringwheel 8 to 13 cm (3 to 5 in), aboutone-eighth turn, until the right fronttire contacts the pavement edge.Then turn the steering wheel togo straight down the roadway.



Loss of ControlLet us review what driving expertssay about what happens when thethree control systems— brakes,steering, and acceleration— do nothave enough friction where the tiresmeet the road to do what the driverhas asked.

In any emergency, do not give up.Keep trying to steer and constantlyseek an escape route or area ofless danger.

Skidding

In a skid, a driver can lose control ofthe vehicle. Defensive drivers avoidmost skids by taking reasonablecare suited to existing conditions,and by not overdriving thoseconditions. But skids are alwayspossible.

The three types of skids correspondto the vehicle's three controlsystems. In the braking skid,the wheels are not rolling. In thesteering or cornering skid, too muchspeed or steering in a curve causestires to slip and lose cornering force.And in the acceleration skid, toomuch throttle causes the drivingwheels to spin.

If the vehicle starts to slide, easeyour foot off the accelerator pedaland quickly steer the way youwant the vehicle to go. If you startsteering quickly enough, the vehiclemay straighten out. Always be readyfor a second skid if it occurs.

Of course, traction is reduced whenwater, snow, ice, gravel, or othermaterial is on the road. For safety,slow down and adjust your driving to

these conditions. It is important toslow down on slippery surfacesbecause stopping distance is longerand vehicle control more limited.

While driving on a surface withreduced traction, try to avoidsudden steering, acceleration,or braking, including reducingvehicle speed by shifting to a lowergear. Any sudden changes couldcause the tires to slide. You mightnot realize the surface is slipperyuntil the vehicle is skidding. Learnto recognize warning clues— suchas enough water, ice, or packedsnow on the road to make amirrored surface— and slowdown when you have any doubt.

Remember: Antilock brakes helpavoid only the braking skid.



Off-Road DrivingVehicles with four-wheel drivecan be used for off-road driving.Vehicles without four-wheel driveand vehicles with 20‐inch tire/wheelassemblies should not be drivenoff-road except on a level, solidsurface.

The airbag system is designed towork properly under a wide rangeof conditions, including off‐roadusage. Always wear your safety beltand observe safe driving speeds,especially on rough terrain.

Drinking and driving can be verydangerous on any road and this iscertainly true for off-road driving.At the very time you need specialalertness and driving skills, yourreflexes, perceptions, and judgmentcan be affected by even a smallamount of alcohol. You could have a

serious — or even fatal — accidentif you drink and drive or ride with adriver who has been drinking.

Off-roading can be great fun but hassome definite hazards. The greatestof these is the terrain itself. Whenoff-road driving, traffic lanes are notmarked, curves are not banked, andthere are no road signs. Surfacescan be slippery, rough, uphill,or downhill.

Avoid sharp turns and abruptmaneuvers. Failure to operate thevehicle correctly off‐road couldresult in loss of vehicle controlor vehicle rollover.

Off-roading involves some newskills. That is why it is veryimportant that you read thesedriving tips and suggestions tohelp make off-road driving saferand more enjoyable.

Before You Go Off-Roading. Have all necessary maintenance

and service work done.. Make sure there is enough fuel,

that fluid levels are where theyshould be, and that the sparetire is fully inflated.

. Be sure to read allthe information aboutfour-wheel-drive vehiclesin this manual.

. Make sure all underbodyshields, if the vehicle has them,are properly attached.

. Know the local laws that applyto off-roading where you willbe driving or check with lawenforcement people in the area.

. Be sure to get the necessarypermission if you will be onprivate land.



If you think you will need somemore ground clearance at the frontof your vehicle, you can remove thefront fascia lower air dam. The airdam is held in place by 2 boltsand 10 snaps accessible fromunderneath the front fascia.

To remove the air dam:

1. Remove the 2 outboard air dambolts.

2. With a flat‐blade tool, disengagethe snaps.

3. After the bolts are removed andthe snaps are disengaged, pushforward on the air dam until itis free.

Notice: Operating your vehiclefor extended periods withoutthe front fascia lower air daminstalled can cause improper airflow to the engine. Always besure to replace the front fasciaair dam when you are finishedoff-road driving.

After off-roading, be sure to reinstallthe air dam:

1. Line up the snaps and push theair dam rearward to engage thesnaps.

2. Install the 2 outboard bolts.

Loading Your Vehicle forOff-Road Driving

{ WARNING

. Cargo on the load floor piledhigher than the seatbackscan be thrown forward duringa sudden stop. You or yourpassengers could be injured.Keep cargo below the top ofthe seatbacks.

. Unsecured cargo on theload floor can be tossedabout when driving overrough terrain. You or yourpassengers can be struckby flying objects. Secure thecargo properly.

(Continued)



WARNING (Continued)

. Heavy loads on the roof raisethe vehicle's center of gravity,making it more likely to rollover. You can be seriously orfatally injured if the vehiclerolls over. Put heavy loadsinside the cargo area, not onthe roof. Keep cargo in thecargo area as far forwardand low as possible.

There are some important things toremember about how to load yourvehicle.. The heaviest things should be

on the floor, forward of the rearaxle. Put heavier items as farforward as you can.

. Be sure the load is properlysecured, so things are nottossed around.

You will find other importantinformation under Vehicle LoadLimits on page 9‑25 and Tires onpage 10‑57.

Environmental Concerns

Off-road driving can providewholesome and satisfyingrecreation. However, it alsoraises environmental concerns.We recognize these concernsand urge every off-roader to followthese basic rules for protectingthe environment:. Always use established trails,

roads, and areas that have beenspecially set aside for publicoff-road recreational driving andobey all posted regulations.

. Avoid any driving practicethat could damage shrubs,flowers, trees, or grasses ordisturb wildlife. This includeswheel-spinning, breaking downtrees, or unnecessary drivingthrough streams or over softground.

. Always carry a litter bag andmake sure all refuse is removedfrom any campsite beforeleaving.

. Take extreme care with openfires (where permitted), campstoves, and lanterns.

. Never park your vehicle overdry grass or other combustiblematerials that could catch firefrom the heat of the vehicle'sexhaust system.



Traveling to Remote Areas

It makes sense to plan your trip,especially when going to a remotearea. Know the terrain and planyour route. Get accurate maps oftrails and terrain. Check to see ifthere are any blocked or closedroads.

It is also a good idea to travel withat least one other vehicle in casesomething happens to one of them.

For vehicles with a winch, be sureto read the winch instructions. In aremote area, a winch can be handyif you get stuck but you will want toknow how to use it properly.

Getting Familiar with Off-RoadDriving

It is a good idea to practice in anarea that is safe and close to homebefore you go into the wilderness.Off-roading requires some new anddifferent skills.

Tune your senses to different kindsof signals. Your eyes need toconstantly sweep the terrain forunexpected obstacles. Your earsneed to listen for unusual tire orengine sounds. Use your arms,hands, feet, and body to respondto vibrations and vehicle bounce.

Controlling the vehicle is the key tosuccessful off-road driving. One ofthe best ways to control the vehicleis to control the speed. At higherspeeds:. You approach things faster and

have less time to react.. There is less time to scan the

terrain for obstacles.

. The vehicle has more bouncewhen driving over obstacles.

. More braking distance isneeded, especially on anunpaved surface.

{ WARNING

When you are driving off-road,bouncing and quick changes indirection can easily throw youout of position. This could causeyou to lose control and crash.So, whether you are driving onor off the road, you and yourpassengers should wear safetybelts.



Scanning the Terrain

Off-road driving can take you overmany different kinds of terrain.Be familiar with the terrain andits many different features.

Surface Conditions: Off-roadingsurfaces can be hard-packed dirt,gravel, rocks, grass, sand, mud,snow, or ice. Each of these surfacesaffects the vehicle's steering,acceleration, and braking in differentways. Depending on the surface,slipping, sliding, wheel spinning,delayed acceleration, poor traction,and longer braking distances canoccur.

Surface Obstacles: Unseen orhidden obstacles can be hazardous.A rock, log, hole, rut, or bump canstartle you if you are not preparedfor them. Often these obstacles arehidden by grass, bushes, snow,or even the rise and fall of theterrain itself.

Some things to consider:. Is the path ahead clear?. Will the surface texture change

abruptly up ahead?. Does the travel take you uphill or

downhill?. Will you have to stop suddenly

or change direction quickly?

When driving over obstacles orrough terrain, keep a firm grip onthe steering wheel. Ruts, troughs,or other surface features can jerkthe wheel out of your hands.

When driving over bumps, rocks,or other obstacles, the wheels canleave the ground. If this happens,even with one or two wheels, youcannot control the vehicle as well orat all.

Because you will be on an unpavedsurface, it is especially important toavoid sudden acceleration, suddenturns, or sudden braking.

Off-roading requires a different kindof alertness from driving on pavedroads and highways. There are noroad signs, posted speed limits,or signal lights. Use good judgmentabout what is safe and what is not.



Driving on Hills

Off-road driving often takes you up,down, or across a hill. Driving safelyon hills requires good judgmentand an understanding of what thevehicle can and cannot do. Thereare some hills that simply cannot bedriven, no matter how well built thevehicle.

{ WARNING

Many hills are simply too steepfor any vehicle. If you drive upthem, you will stall. If you drivedown them, you cannot controlyour speed. If you drive acrossthem, you will roll over. You couldbe seriously injured or killed.If you have any doubt about thesteepness, do not drive the hill.

Approaching a Hill

When you approach a hill, decideif it is too steep to climb, descend,or cross. Steepness can be hardto judge. On a very small hill, forexample, there may be a smooth,constant incline with only a smallchange in elevation where you caneasily see all the way to the top.On a large hill, the incline may getsteeper as you near the top, butyou might not see this because thecrest of the hill is hidden by bushes,grass, or shrubs.

Consider this as you approach a hill:. Is there a constant incline,

or does the hill get sharplysteeper in places?

. Is there good traction on thehillside, or will the surface causetire slipping?

. Is there a straight path upor down the hill so you willnot have to make turningmaneuvers?

. Are there obstructions on the hillthat can block your path, suchas boulders, trees, logs, or ruts?

. What is beyond the hill? Isthere a cliff, an embankment, adrop-off, a fence? Get out andwalk the hill if you do not know.It is the smart way to find out.

. Is the hill simply too rough?Steep hills often have ruts,gullies, troughs, and exposedrocks because they are moresusceptible to the effects oferosion.



Driving Uphill

Once you decide it is safe to driveup the hill:. Use a low gear and get a firm

grip on the steering wheel.. Get a smooth start up the hill

and try to maintain speed.Not using more power thanneeded can avoid spinningthe wheels or sliding.

{ WARNING

Turning or driving across steephills can be dangerous. You couldlose traction, slide sideways, andpossibly roll over. You could beseriously injured or killed. Whendriving up hills, always try to gostraight up.

. Try to drive straight up the hill ifat all possible. If the path twistsand turns, you might want to findanother route.

. Ease up on the speed as youapproach the top of the hill.

. Attach a flag to the vehicle tobe more visible to approachingtraffic on trails or hills.

. Sound the horn as you approachthe top of the hill to let opposingtraffic know you are there.

. Use headlamps even during theday to make the vehicle morevisible to oncoming traffic.

{ WARNING

Driving to the top (crest) of ahill at full speed can cause anaccident. There could be adrop-off, embankment, cliff,or even another vehicle. Youcould be seriously injured orkilled. As you near the top of ahill, slow down and stay alert.

If the vehicle stalls, or is about tostall, and you cannot make it upthe hill:. Push the brake pedal to stop

the vehicle and keep it fromrolling backwards and applythe parking brake.

. If the engine is still running, shiftthe transmission to R (Reverse),release the parking brake, andslowly back down the hill inR (Reverse).

. If the engine has stoppedrunning, you need to restart it.With the brake pedal pressedand the parking brake stillapplied, shift the transmission toP (Park) and restart the engine.Then, shift to R (Reverse),release the parking brake,and slowly back down thehill as straight as possiblein R (Reverse).



. While backing down the hill, putyour left hand on the steeringwheel at the 12 o'clock positionso you can tell if the wheels arestraight and can maneuver asyou back down. It is best to backdown the hill with the wheelsstraight rather than in the leftor right direction. Turning thewheel too far to the left or rightwill increase the possibility of arollover.

Things not to do if the vehicle stalls,or is about to stall, when going upa hill:. Never attempt to prevent a stall

by shifting into N (Neutral) torev-up the engine and regainforward momentum. This willnot work. The vehicle can rollbackward very quickly andcould go out of control.

. Never try to turn around if aboutto stall when going up a hill.If the hill is steep enough tostall the vehicle, it is steepenough to cause it to roll over.If you cannot make it up the hill,back straight down the hill.

If, after stalling, you try to backdown the hill and decide you justcannot do it, set the parking brake,put your transmission in P (Park),and turn off the engine. Leavethe vehicle and go get some help.Exit on the uphill side and stay clearof the path the vehicle would takeif it rolled downhill. Do not shift thetransfer case to Neutral when youleave the vehicle. Leave it insome gear.

{ WARNING

Shifting the transfer case toNeutral can cause your vehicle toroll even if the transmission is inP (Park). This is because theNeutral position on the transfercase overrides the transmission.You or someone else could beinjured. If you are going to leaveyour vehicle, set the parkingbrake and shift the transmissionto P (Park). But do not shift thetransfer case to Neutral.



Driving Downhill

When off-roading takes youdownhill, consider:. How steep is the downhill? Will I

be able to maintain vehiclecontrol?

. What is the surface like?Smooth? Rough? Slippery?Hard-packed dirt? Gravel?

. Are there hidden surfaceobstacles? Ruts? Logs?Boulders?

. What is at the bottom of the hill?Is there a hidden creek bank oreven a river bottom with largerocks?

If you decide you can go downa hill safely, try to keep the vehicleheaded straight down. Use a lowgear so engine drag can help thebrakes so they do not have to do allthe work. Descend slowly, keepingthe vehicle under control at alltimes.

{ WARNING

Heavy braking when goingdown a hill can cause yourbrakes to overheat and fade.This could cause loss of controland a serious accident. Apply thebrakes lightly when descending ahill and use a low gear to keepvehicle speed under control.

Things not to do when driving downa hill:. When driving downhill, avoid

turns that take you across theincline of the hill. A hill that isnot too steep to drive downmight be too steep to driveacross. The vehicle couldroll over.

. Never go downhill with thetransmission in N (Neutral),called free-wheeling. The brakeswill have to do all the work andcould overheat and fade.

Vehicles are much more likely tostall when going uphill, but if ithappens when going downhill:

1. Stop the vehicle by applying theregular brakes and apply theparking brake.

2. Shift to P (Park) and, while stillbraking, restart the engine.

3. Shift back to a low gear, releasethe parking brake, and drivestraight down.

4. If the engine will not start, getout and get help.



Driving Across an Incline

An off-road trail will probably goacross the incline of a hill. To decidewhether to try to drive across theincline, consider the following:

{ WARNING

Driving across an incline that istoo steep will make your vehicleroll over. You could be seriouslyinjured or killed. If you have anydoubt about the steepness of theincline, do not drive across it.Find another route instead.

. A hill that can be driven straightup or down might be too steepto drive across. When goingstraight up or down a hill, thelength of the wheel base — thedistance from the front wheels tothe rear wheels — reduces thelikelihood the vehicle will tumble

end over end. But when drivingacross an incline, the narrowertrack width — the distancebetween the left and rightwheels — might not prevent thevehicle from tilting and rollingover. Driving across an inclineputs more weight on the downhillwheels which could cause adownhill slide or a rollover.

. Surface conditions can be aproblem. Loose gravel, muddyspots, or even wet grass cancause the tires to slip sideways,downhill. If the vehicle slipssideways, it can hit somethingthat will trip it — a rock, a rut,etc. — and roll over.

. Hidden obstacles can make thesteepness of the incline evenworse. If you drive across a rockwith the uphill wheels, or if thedownhill wheels drop into a rutor depression, the vehicle can tilteven more.

For these reasons, carefullyconsider whether to try to driveacross an incline. Just becausethe trail goes across the inclinedoes not mean you have to drive it.The last vehicle to try it might haverolled over.

If you feel the vehicle startingto slide sideways, turn downhill.This should help straighten outthe vehicle and prevent the sideslipping. The best way to preventthis is to “walk the course” first, soyou know what the surface is likebefore driving it.



Stalling on an Incline

{ WARNING

Getting out on the downhill (low)side of a vehicle stopped acrossan incline is dangerous. If thevehicle rolls over, you could becrushed or killed. Always get outon the uphill (high) side of thevehicle and stay well clear of therollover path.

If the vehicle stalls when crossingan incline, be sure you, andany passengers, get out on theuphill side, even if the door thereis harder to open. If you get out onthe downhill side and the vehiclestarts to roll over, you will be rightin its path.

If you have to walk down the slope,stay out of the path the vehicle willtake if it does roll over.

Driving in Mud, Sand, Snow,or Ice

When you drive in mud, snow,or sand, the wheels do not getgood traction. Acceleration is notas quick, turning is more difficult,and braking distances are longer.

It is best to use a low gear whenin mud — the deeper the mud, thelower the gear. In really deep mud,keep the vehicle moving so it doesnot get stuck.

When driving on sand, wheeltraction changes. On loosely packedsand, such as on beaches or sanddunes, the tires will tend to sink intothe sand. This affects steering,accelerating, and braking. Drive ata reduced speed and avoid sharpturns or abrupt maneuvers.

Hard packed snow and ice offerthe worst tire traction. On thesesurfaces, it is very easy to losecontrol. On wet ice, for example,the traction is so poor that youwill have difficulty accelerating.And, if the vehicle does get moving,poor steering and difficult brakingcan cause it to slide out of control.

{ WARNING

Driving on frozen lakes, ponds,or rivers can be dangerous.Underwater springs, currentsunder the ice, or sudden thawscan weaken the ice. Your vehiclecould fall through the ice andyou and your passengers coulddrown. Drive your vehicle on safesurfaces only.



Driving in Water

{ WARNING

Driving through rushing water canbe dangerous. Deep water cansweep your vehicle downstreamand you and your passengerscould drown. If it is only shallowwater, it can still wash away theground from under your tires, andyou could lose traction and rollthe vehicle over. Do not drivethrough rushing water.

Heavy rain can mean flash flooding,and flood waters demand extremecaution.

Find out how deep the water isbefore driving through it. Do nottry it if it is deep enough to coverthe wheel hubs, axles, or exhaustpipe — you probably will not getthrough. Deep water can damagethe axle and other vehicle parts.

If the water is not too deep, driveslowly through it. At faster speeds,water splashes on the ignitionsystem and the vehicle can stall.Stalling can also occur if you get thetailpipe under water. If the tailpipe isunder water, you will never be ableto start the engine. When goingthrough water, remember that whenthe brakes get wet, it might takelonger to stop. See Driving on WetRoads on page 9‑19.

After Off-Road Driving

Remove any brush or debris thathas collected on the underbody,chassis, or under the hood. Theseaccumulations can be a fire hazard.

After operation in mud or sand,have the brake linings cleaned andchecked. These substances cancause glazing and uneven braking.Check the body structure, steering,suspension, wheels, tires, andexhaust system for damage andcheck the fuel lines and coolingsystem for any leakage.

The vehicle requires more frequentservice due to off-road use. Referto the Maintenance Schedule foradditional information.



Driving on Wet RoadsRain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep‐standing or flowing water.

{ WARNING

Wet brakes can cause crashes.They might not work as well ina quick stop and could causepulling to one side. You couldlose control of the vehicle.

(Continued)

WARNING (Continued)

After driving through a largepuddle of water or a car/vehiclewash, lightly apply the brakepedal until the brakes worknormally.

Flowing or rushing water createsstrong forces. Driving throughflowing water could cause thevehicle to be carried away. If thishappens, you and other vehicleoccupants could drown. Do notignore police warnings and bevery cautious about trying todrive through flowing water.

Hydroplaning

Hydroplaning is dangerous. Watercan build up under the vehicle'stires so they actually ride on thewater. This can happen if the roadis wet enough and you are goingfast enough. When the vehicle ishydroplaning, it has little or nocontact with the road.

There is no hard and fast rule abouthydroplaning. The best advice is toslow down when the road is wet.



Other Rainy Weather Tips

Besides slowing down, other wetweather driving tips include:. Allow extra following distance.. Pass with caution.. Keep windshield wiping

equipment in good shape.. Keep the windshield washer fluid

reservoir filled.. Have good tires with proper

tread depth. See Tires onpage 10‑57.

. Turn off cruise control.

Highway HypnosisAlways be alert and pay attentionto your surroundings while driving.If you become tired or sleepy, finda safe place to park the vehicleand rest.

Other driving tips include:. Keep the vehicle well ventilated.. Keep interior temperature cool.. Keep your eyes moving — scan

the road ahead and to the sides.. Check the rearview mirror and

vehicle instruments often.

Hill and Mountain RoadsDriving on steep hills or throughmountains is different than drivingon flat or rolling terrain. Tips fordriving in these conditions include:. Keep the vehicle serviced and in

good shape.. Check all fluid levels and brakes,

tires, cooling system, andtransmission.

. Shift to a lower gear when goingdown steep or long hills.

{ WARNING

If you do not shift down, thebrakes could get so hot that theywould not work well. You wouldthen have poor braking or evennone going down a hill. You couldcrash. Shift down to let the engineassist the brakes on a steepdownhill slope.



{ WARNING

Coasting downhill in N (Neutral)or with the ignition off isdangerous. The brakes willhave to do all the work of slowingdown and they could get so hotthat they would not work well.You would then have poor brakingor even none going down a hill.You could crash. Always have theengine running and the vehicle ingear when going downhill.

. Stay in your own lane. Do notswing wide or cut across thecenter of the road. Drive atspeeds that let you stay inyour own lane.

. Top of hills: Be alert —something could be in yourlane (stalled car, accident).

. Pay attention to special roadsigns (falling rocks area, windingroads, long grades, passing orno-passing zones) and takeappropriate action.

Winter Driving

Driving on Snow or Ice

Drive carefully when there is snowor ice between the tires and theroad, creating less traction or grip.Wet ice can occur at about 0°C(32°F) when freezing rain begins tofall, resulting in even less traction.Avoid driving on wet ice or infreezing rain until roads can betreated with salt or sand.

Drive with caution, whatever thecondition. Accelerate gently sotraction is not lost. Accelerating tooquickly causes the wheels to spinand makes the surface under thetires slick, so there is even lesstraction.

Try not to break the fragile traction.If you accelerate too fast, the drivewheels will spin and polish thesurface under the tires even more.

The Antilock Brake System (ABS)on page 9‑68 improves vehiclestability during hard stops onslippery roads, but apply the brakessooner than when on dry pavement.

Allow greater following distance onany slippery road and watch forslippery spots. Icy patches canoccur on otherwise clear roads inshaded areas. The surface of acurve or an overpass can remainicy when the surrounding roadsare clear. Avoid sudden steeringmaneuvers and braking whileon ice.

Turn off cruise control on slipperysurfaces.



Blizzard Conditions

Being stuck in snow can be aserious situation. Stay with thevehicle unless there is help nearby.If possible, use the RoadsideAssistance Program (U.S. andCanada) on page 13‑8 or RoadsideAssistance Program (Mexico) onpage 13‑10. To get help and keepeveryone in the vehicle safe:. Turn on the hazard warning

flashers.. Tie a red cloth to an outside

mirror.

{ WARNING

Snow can trap engine exhaustunder the vehicle. This maycause exhaust gases to getinside. Engine exhaust containsCarbon Monoxide (CO) whichcannot be seen or smelled.It can cause unconsciousnessand even death.

(Continued)

WARNING (Continued)

If the vehicle is stuck in the snow:. Clear away snow from aroundthe base of your vehicle,especially any that is blockingthe exhaust pipe.

. Check again from time totime to be sure snow doesnot collect there.

. Open a window about 5 cm(2 in) on the side of thevehicle that is away fromthe wind to bring in fresh air.

. Fully open the air outletson or under the instrumentpanel.

. Adjust the climate controlsystem to a setting thatcirculates the air insidethe vehicle and set the fanspeed to the highest setting.See Climate Control Systemin the Index.

(Continued)

WARNING (Continued)

For more information aboutcarbon monoxide, see EngineExhaust on page 9‑44.

Snow can trap exhaust gasesunder your vehicle. This cancause deadly CO (CarbonMonoxide) gas to get inside.CO could overcome you and killyou. You cannot see it or smell it,so you might not know it is in yourvehicle. Clear away snow fromaround the base of your vehicle,especially any that is blocking theexhaust.

Run the engine for short periodsonly as needed to keep warm, butbe careful.



To save fuel, run the engine for onlyshort periods as needed to warmthe vehicle and then shut the engineoff and close the window most ofthe way to save heat. Repeat thisuntil help arrives but only when youfeel really uncomfortable from thecold. Moving about to keep warmalso helps.

If it takes some time for help toarrive, now and then when you runthe engine, push the acceleratorpedal slightly so the engine runsfaster than the idle speed. Thiskeeps the battery charged to restartthe vehicle and to signal for helpwith the headlamps. Do this as littleas possible to save fuel.

If the Vehicle is StuckSlowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.See “Rocking Your Vehicle to GetIt Out” later in this section.

If the vehicle has a traction system,it can often help to free a stuckvehicle. Refer to the vehicle'straction system in the Index. If stucktoo severely for the traction systemto free the vehicle, turn the tractionsystem off and use the rockingmethod.

{ WARNING

If the vehicle's tires spin at highspeed, they can explode, andyou or others could be injured.The vehicle can overheat,causing an engine compartmentfire or other damage. Spin thewheels as little as possible andavoid going above 55 km/h(35 mph).

For information about using tirechains on the vehicle, see TireChains on page 10‑83.



Rocking Your Vehicle to GetIt Out

Turn the steering wheel left andright to clear the area around thefront wheels. For four-wheel-drivevehicles, shift into Four‐WheelHigh. For vehicles with StabiliTrak®,turn the traction control part of thesystem off. Shift back and forthbetween R (Reverse) and a forwardgear, spinning the wheels as little aspossible. To prevent transmissionwear, wait until the wheels stopspinning before shifting gears.Release the accelerator pedalwhile shifting, and press lightlyon the accelerator pedal whenthe transmission is in gear. Slowlyspinning the wheels in the forwardand reverse directions causes arocking motion that could free the

vehicle. If that does not get thevehicle out after a few tries, it mightneed to be towed out. Recoveryhooks can be used, if the vehiclehas them. If the vehicle does needto be towed out, see Towing theVehicle on page 10‑103.

Recovery Hooks

{ WARNING

These hooks, when used, areunder a lot of force. Always pullthe vehicle straight out. Never pullon the hooks at a sideways angle.The hooks could break off andyou or others could be injuredfrom the chain or cablesnapping back.

Notice: Never use recoveryhooks to tow the vehicle.Your vehicle could be damagedand it would not be covered bywarranty.

For vehicles with recovery hooks atthe front of the vehicle, you can usethem if you are stuck off-road andneed to be pulled to some placewhere you can continue driving.



Vehicle Load LimitsIt is very important to knowhow much weight your vehiclecan carry. This weight is calledthe vehicle capacity weightand includes the weight ofall occupants, cargo, and allnonfactory-installed options.Two labels on your vehicleshow how much weight it wasdesigned to carry, the Tire andLoading Information label andthe Certification/Tire label.

{ WARNING

Do not load the vehicleany heavier than theGross Vehicle WeightRating (GVWR), or either themaximum front or rear GrossAxle Weight Rating (GAWR).This can cause systems tobreak and change the way thevehicle handles. This couldcause loss of control and acrash. Overloading can alsoshorten the life of the vehicle.

Tire and Loading InformationLabel

Label Example

A vehicle specific Tire andLoading Information label isattached to the center pillar(B-pillar). With the driverdoor open, you will find thelabel attached below thedoor lock post (striker).



The tire and loading informationlabel shows the number ofoccupant seating positions (A),and the maximum vehiclecapacity weight (B) in kilogramsand pounds.

The Tire and LoadingInformation label also shows thesize of the original equipmenttires (C) and the recommendedcold tire inflation pressures (D).For more information on tiresand inflation see Tires onpage 10‑57 and Tire Pressureon page 10‑66.

There is also important loadinginformation on the vehicleCertification/Tire label. It tellsyou the Gross Vehicle WeightRating (GVWR) and the GrossAxle Weight Rating (GAWR)for the front and rear axles.See “Certification/Tire Label”later in this section.

Steps for Determining CorrectLoad Limit

1. Locate the statement“The combined weight ofoccupants and cargo shouldnever exceed XXX kg orXXX lbs” on your vehicle'splacard.

2. Determine the combinedweight of the driver andpassengers that will beriding in your vehicle.

3. Subtract the combinedweight of the driver andpassengers from XXX kgor XXX lbs.

4. The resulting figure equalsthe available amount of cargoand luggage load capacity.For example, if the “XXX”amount equals 1400 lbsand there will be five 150 lbpassengers in your vehicle,the amount of available cargoand luggage load capacityis 650 lbs (1400−750(5x150) = 650 lbs).



5. Determine the combinedweight of luggage and cargobeing loaded on the vehicle.That weight may not safelyexceed the available cargoand luggage load capacitycalculated in Step 4.

6. If your vehicle will be towinga trailer, the load from yourtrailer will be transferred toyour vehicle. Consult thismanual to determine how thisreduces the available cargoand luggage load capacityof your vehicle. SeeTrailerTowing on page 9‑95 forimportant information ontowing a trailer, towing safetyrules and trailering tips.

Example 1

A. Vehicle Capacity Weight forExample 1 = (453 kg) (1,000 lbs)

B. Subtract Occupant Weight @68 kg (150 lbs) × 2 = 136 kg(300 lbs)

C. Available Occupant and CargoWeight = 317 kg (700 lbs)

Example 2

A. Vehicle Capacity Weight forExample 2 = 453 kg (1,000 lbs)

B. Subtract Occupant Weight @68 kg (150 lbs) × 5 = 340 kg(750 lbs)

C. Available CargoWeight = 113 kg (250 lbs)



Example 3

A. Vehicle Capacity Weight forExample 3 = 453 kg (1,000 lbs)

B. Subtract Occupant Weight @91 kg (200 lbs) × 5 = 453 kg(1,000 lbs)

C. Available CargoWeight = 0 kg (0 lbs)

Refer to your vehicle's tire andloading information label forspecific information about yourvehicle's capacity weight andseating positions. The combinedweight of the driver, passengers,and cargo should never exceedyour vehicle's capacity weight.

Certification/Tire Label

A vehicle specific Certification/Tire label is found on therear edge of the driver door.

The label shows the size ofyour vehicle's original tires andthe inflation pressures neededto obtain the gross weightcapacity of your vehicle. This iscalled Gross Vehicle WeightRating (GVWR). The GVWRincludes the weight of thevehicle, all occupants, fuel,and cargo.

The Certification/Tire label alsotells you the maximum weightsfor the front and rear axles,called Gross Axle WeightRating (GAWR). To find out theactual loads on your front andrear axles, you need to go to aweigh station and weigh yourvehicle. Your dealer can helpyou with this. Be sure to spreadout your load equally on bothsides of the centerline.



Never exceed the GVWR foryour vehicle, or the GAWR foreither the front or rear axle.

The Certification/Tire label alsocontains important informationabout your Front Axle ReserveCapacity. See “What is front axlereserve capacity, and how do Icalculate it?” under Adding aSnow Plow or Similar Equipmenton page 9‑125.

{ WARNING

In the case of a sudden stopor collision, things carried inthe bed of your truck couldshift forward and come intothe passenger area, injuringyou and others. If you putthings in the bed of your truck,you should make sure theyare properly secured.

{ WARNING

Do not load the vehicle anyheavier than the GrossVehicle Weight Rating(GVWR), or either themaximum front or rear GrossAxle Weight Rating (GAWR).This can cause systems tobreak and change the way thevehicle handles. This couldcause loss of control and acrash. Overloading can alsoshorten the life of the vehicle.

Notice : Overloading thevehicle may cause damage.Repairs would not be coveredby the vehicle warranty.Do not overload the vehicle.

Using heavier suspensioncomponents to get addeddurability might not changeyour weight ratings. Ask yourdealer to help you load yourvehicle the right way.



If you put things inside yourvehicle— like suitcases,tools, packages, or anythingelse— they go as fast as thevehicle goes. If you have tostop or turn quickly, or if thereis a crash, they will keep going.

{ WARNING

Things you put inside thevehicle can strike and injurepeople in a sudden stop orturn, or in a crash.

. Put things in the cargoarea of the vehicle. Try tospread the weight evenly.

. Never stack heavierthings, like suitcases,inside the vehicle so thatsome of them are abovethe tops of the seats.

(Continued)

WARNING (Continued)

. Do not leave anunsecured child restraintin the vehicle.

. When you carry somethinginside the vehicle, secureit whenever you can.

. Do not leave a seat foldeddown unless you need to.

There is also important loadinginformation for off-road driving inthis manual. See “Loading YourVehicle for Off-Road Driving“under Off-Road Driving onpage 9‑7.

Two-Tiered Loading

Depending on the model of yourpick‐up, an upper load platformcan be created by positioningthree or four 5 cm (2 inches) by15 cm (6 inches) wooden planksacross the width of the pickupbox. The planks must beinserted in the pickup boxdepressions.

When using this upper loadplatform, be sure the load issecurely tied down to prevent itfrom shifting. The load's centerof gravity should be positionedin a zone over the rear axle.The zone is located in the areabetween the front of each wheelwell and the rear of each wheelwell. The center of gravity heightmust not extend above the topof the pickup box flareboard.



Any load that extends beyondthe vehicle's taillamp area mustbe properly marked according tolocal laws and regulations.

Remember not to exceedthe Gross Axle WeightRating (GAWR) of the frontor rear axle.

Add-On Equipment

When you carry removableitems, you may need to puta limit on how many peopleyou carry inside your vehicle.Be sure to weigh your vehiclebefore you buy and install thenew equipment.

Notice : Overloading thevehicle may cause damage.Repairs would not be coveredby the vehicle warranty.Do not overload the vehicle.

Remember not to exceedthe Gross Axle WeightRating (GAWR) of the frontor rear axle.

The holes for the CargoManagement System (C) arenot intended for attachmentof aftermarket equipment.See www.gmupfitter.com foradditional pick-up box loadbearing structural information.

Truck-Camper LoadingInformationA vehicle-specific Truck‐CamperLoading Information label isattached to the inside of thevehicle's glove box. This labelindicates if a slide-in campercan be carried, how much of aload the vehicle can carry, andhow to correctly spread out theload. It will help to match theright slide in camper to thevehicle.

Your dealer can help make agood vehicle-camper matchand help determine the CargoWeight Rating (CWR).

When installing and loading aslide-in camper, check themanufacturer's instructions.

When carrying a slide-incamper, the total cargo load ofthe vehicle is the weight of thecamper, plus the following:. Everything added to the

camper after it left the factory. Everything in the camper. All the people inside

The CWR is the maximumweight of the load the vehiclecan carry. It does not includethe weight of the people inside.But, use about 68 kg (150 lbs)for each seat.

The total cargo load must not bemore than the vehicle's CWR.

Refer to the Truck-CamperLoading Information label in theglove box for dimensions A andB as shown in the followingillustration.

Use the rear edge of the loadfloor for measurement purposes.The recommended locationfor the cargo center of gravityis at point C for the CWR. It isthe point where the mass ofa body is concentrated and,if suspended at that point, wouldbalance the front and rear.



Here is an example of propertruck and camper match:

A. Camper Center of Gravity

B. Recommended Center ofGravity Location Zone

When the truck is used to carrya slide‐in camper, the total cargoload of the truck consists of themanufacturer's camper weightfigure, the weight of installedadditional camper equipment notincluded in the manufacturer'scamper weight figure, the weightof camper cargo, and the weightof passengers in the camper.The total cargo load shouldnot exceed the truck's cargoweight rating, and the camper'scenter of gravity (A) should fallwithin the truck's recommendedcenter of gravity zone (B) wheninstalled.

Any accessories or otherequipment that are added tothe vehicle must be weighed.Then, subtract this extra weightfrom the CWR. This extra weightmay shorten the center ofgravity zone of the vehicle.

If the slide-in camper and itsload weighs less than the CWR,the center of gravity zone foryour vehicle may be larger.

Secure loose items to preventweight shifts that could affectthe balance of the vehicle.



When the truck‐camper isloaded, drive to a scale andweigh on the front and on therear wheels separately todetermine axle loads. Individualaxle loads should not exceedeither of the gross axle weightratings (GAWR). The total axleloads should not exceed yourvehicle's gross vehicle weightrating (GVWR). These ratingsare given on the vehiclecertification label attached tothe rear edge of the driver door.See “Certification/Tire Label”under Vehicle Load Limits onpage 9‑25. If weight ratingsare exceeded, move or removeitems to bring all weights belowthe ratings.

See your dealer for moreinformation on curb weights,cargo weights, Cargo WeightRating and the correct centerof gravity zone.

Starting andOperating

New Vehicle Break-InNotice: The vehicle does notneed an elaborate break-in. But itwill perform better in the long runif you follow these guidelines:. Keep the vehicle speed at88 km/h (55mph) or less forthe first 805 km (500miles).

. Do not drive at any oneconstant speed, fast orslow, for the first 805 km(500miles). Do not makefull-throttle starts. Avoiddownshifting to brake orslow the vehicle.

. Avoid making hard stops forthe first 322 km (200miles)or so. During this time thenew brake linings are notyet broken in. Hard stopswith new linings can meanpremature wear and earlierreplacement. Follow thisbreaking-in guideline everytime you get new brakelinings.

. Do not tow a trailer duringbreak-in. See TrailerTowing on page 9‑95 for thetrailer towing capabilitiesof the vehicle and moreinformation.

Following break‐in, engine speedand load can be graduallyincreased.



Adjustable Throttle andBrake PedalOn vehicles with this feature, youcan change the position of thethrottle and brake pedals.

No adjustment to the pedals canbe made when the vehicle is inR (Reverse) or while using cruisecontrol.

The control used to adjust thepedals is located on the instrumentpanel below the climate controlsystem.

Press the bottom of the control tomove the pedals closer. Press thetop of the control to move thepedals away.

Before you start driving, fullypress the brake pedal to confirmthe adjustment is right for you.While driving, make only smalladjustments.

The vehicle may have a memoryfunction which lets pedal settingsbe saved and recalled. See PowerSeat Adjustment on page 3‑4 formore information.

Ignition Positions

The ignition switch has four differentpositions.

To shift out of P (Park), theignition must be in ON/RUN orACC/ACCESSORY and the regularbrake pedal must be applied.



A (STOPPING THE ENGINE/LOCK/OFF): When the vehicle isstopped, turn the ignition switch toLOCK/OFF to turn the engine off.Retained Accessory Power (RAP)will remain active. See RetainedAccessory Power (RAP) onpage 9‑40.

This position locks the ignition.It also locks the transmission onautomatic transmission vehicles.The key can be removed inLOCK/OFF.

Do not turn the engine off when thevehicle is moving. This will cause aloss of power assist in the brakeand steering systems and disablethe airbags.

In an emergency:

1. Brake using a firm and steadypressure. Do not pump thebrakes repeatedly. This maydeplete power assist, requiringincreased brake pedal force.

2. Shift the vehicle to neutral. Thiscan be done while the vehicle ismoving. After shifting to neutral,firmly apply the brakes and steerthe vehicle to a safe location.

3. Come to a complete stop, shiftto P (Park), and turn the ignitionto LOCK/OFF. On vehicles withan automatic transmission, theshift lever must be in P (Park)to turn the ignition switch to theLOCK/OFF position.

4. Set the parking brake. SeeParking Brake on page 9‑69.

The steering can bind with thewheels turned off center. If thishappens, move the steering wheelfrom right to left while turning thekey to ACC/ACCESSORY. If thisdoesn't work, then the vehicleneeds service.

Notice: Using a tool to force thekey to turn in the ignition couldcause damage to the switch orbreak the key. Use the correctkey, make sure it is all the way in,and turn it only with your hand.If the key cannot be turned byhand, see your dealer.

B (ACC/ACCESSORY): Thisposition lets things like the radioand the windshield wipers operatewhile the engine is off. Use thisposition if the vehicle must bepushed or towed.



C (ON/RUN): This position canbe used to operate the electricalaccessories and to display someinstrument panel cluster warningand indicator lights. The switchstays in this position when theengine is running. The transmissionis also unlocked in this position onautomatic transmission vehicles.

If you leave the key in theACC/ACCESSORY or ON/RUNposition with the engine off, thebattery could be drained. You maynot be able to start the vehicle if thebattery is allowed to drain for anextended period of time.

D (START): This is the position thatstarts the engine. When the enginestarts, release the key. The ignitionswitch returns to ON/RUN fordriving.

A warning tone will sound whenthe driver door is opened and theignition is in ACC/ACCESSORY orLOCK/OFF, and the key is in theignition.

Starting the EngineIf the vehicle has a Duramax dieselengine, see the Duramax dieselsupplement for more information.


Notice: Do not try to shift toP (Park) if the vehicle is moving.If you do, you could damage thetransmission. Shift to P (Park)only when the vehicle is stopped.

Move the shift lever to P (Park) orN (Neutral). The engine will not startin any other position. To restart theengine when the vehicle is alreadymoving, use N (Neutral) only.

Notice: The engine is designed towork with the electronics in thevehicle. If you add electrical partsor accessories, you could changethe way the engine operates.

Before adding electricalequipment, check with yourdealer. If you do not, the enginemight not perform properly.Any resulting damage wouldnot be covered by the vehiclewarranty.

Starting Procedure

1. With your foot off the acceleratorpedal, turn the ignition key toSTART. When the engine starts,let go of the key. The idle speedwill go down as your engine getswarm. Do not race the engineimmediately after starting it.Operate the engine andtransmission gently to allowthe oil to warm up and lubricateall moving parts.



The vehicle has aComputer-ControlledCranking System. This featureassists in starting the engineand protects components.If the ignition key is turnedto the START position, andthen released when the enginebegins cranking, the enginewill continue cranking for afew seconds or until the vehiclestarts. If the engine does notstart and the key is held inSTART for many seconds,cranking will be stopped after15 seconds to prevent crankingmotor damage. To preventgear damage, this system alsoprevents cranking if the engineis already running. Enginecranking can be stopped byturning the ignition switch tothe ACC/ACCESSORY orLOCK/OFF position.

When the Low Fuel warninglamp is on and the FUEL LEVELLOW message is displayed inthe Driver Information Center(DIC), the Computer‐ControlledCranking System is disabledto prevent possible vehiclecomponent damage. Whenthis happens, hold the ignitionswitch in the START positionto continue engine cranking.

Notice: Cranking the engine forlong periods of time, by returningthe key to the START positionimmediately after cranking hasended, can overheat and damagethe cranking motor, and drain thebattery. Wait at least 15 secondsbetween each try, to let thecranking motor cool down.

2. If the engine does not startafter 5‐10 seconds, especiallyin very cold weather (below−18°C or 0°F), it could beflooded with too much gasoline.Try pushing the acceleratorpedal all the way to the floorand holding it there as youhold the key in START for upto 15 seconds. Wait at least15 seconds between each try, toallow the cranking motor to cooldown. When the engine starts,let go of the key and accelerator.If the vehicle starts briefly butthen stops again, do the samething. This clears the extragasoline from the engine. Do notrace the engine immediatelyafter starting it. Operate theengine and transmission gentlyuntil the oil warms up andlubricates all moving parts.



Fast Idle SystemIf the vehicle has this feature it isavailable only with cruise control.The manual fast idle switch isoperated using the cruise controlbuttons located on the left handside of the steering wheel.

This system can be used toincrease engine idle speedwhenever the following conditionsare met:. The park brake is set.. The brake pedal is not pressed.. The vehicle must not be moving

and the accelerator must not bepressed.

To control the fast idle:. To enable the Fast Idle System,

press and release the CruiseControl On/Off button andensure that the switch LED is lit.

. Press and release the CruiseControl Set switch. Enginespeed will be held atapproximately 1200 RPM.

When the fast idle is active theDriver Information Center (DIC) willdisplay “FAST IDLE ON.”

One of the following actions will turnoff the fast idle:. Pressing the brake.. Selecting the Cruise Control

Cancel button.

. Releasing the Parking Brake.

. The transmission shifter ismoved out of P (Park) orN (Neutral).

. Selecting the Cruise ControlOn/Off button when it waspreviously on.

. Pressing the Cruise Control Setswitch a second time.

. Pressing the accelerator greaterthan a quarter of the down.

. Turning the ignition switch to theLOCK/OFF position.



Retained AccessoryPower (RAP)The following vehicle accessoriescan be used for up to 10 minutesafter the engine is turned off:. Audio System. Power Windows. OnStar System (if equipped). Sunroof (if equipped)

These features work whenthe key is in ON/RUN orACC/ACCESSORY. Oncethe key is turned from ON/RUNto LOCK/OFF, the windows andsunroof continue to work up to10 minutes until any door is opened.The radio continues to work forup to 10 minutes or until the driverdoor is opened.

Engine Coolant HeaterThe engine heater can provideeasier starting and better fueleconomy during engine warm-upin cold weather conditions ator below −18°C (0°F). Vehicleswith an engine heater should beplugged in at least four hours beforestarting. An internal thermostat inthe plug-end of the cord may existwhich will prevent engine coolantheater operation at temperaturesabove −18°C (0°F).

If the vehicle has a diesel engine,see the Duramax Diesel supplementfor more information.

To Use the Engine CoolantHeater

1. Turn off the engine.

2. Open the hood and unwrapthe electrical cord. The cordis secured to the EngineCompartment Fuse Blockwith a clip. Carefully removethe wire tie which bundles theelectrical plug. Do not cut theelectrical cord.

3. Plug the cord into a normal,grounded 110-volt AC outlet.

{ WARNING

Plugging the cord into anungrounded outlet could causean electrical shock. Also, thewrong kind of extension cordcould overheat and cause a fire.

(Continued)



WARNING (Continued)

You could be seriously injured.Plug the cord into a properlygrounded three-prong 110-volt ACoutlet. If the cord will not reach,use a heavy-duty three-prongextension cord rated for at least15 amps.

4. Before starting the engine, besure to unplug and store thecord as it was before to keepit away from moving engineparts. If you do not, it couldbe damaged.

The length of time the heater shouldremain plugged in depends onseveral factors. Ask a dealer in thearea where you will be parking thevehicle for the best advice on this.

Shifting Into Park

{ WARNING

It can be dangerous to get out ofthe vehicle if the shift lever is notfully in P (Park) with the parkingbrake firmly set. The vehicle canroll. If you have left the enginerunning, the vehicle can movesuddenly. You or others couldbe injured. To be sure the vehiclewill not move, even when you areon fairly level ground, use thesteps that follow. With four-wheeldrive, if the transfer case is inN (Neutral), the vehicle will befree to roll, even if the shift leveris in P (Park). So, be sure thetransfer case is in a drivegear— not in N (Neutral). If youare pulling a trailer, see DrivingCharacteristics and Towing Tipson page 9‑91.

1. Hold the brake pedal down, thenset the parking brake.

See Parking Brake on page 9‑69for more information.

2. Move the shift lever into theP (Park) position by pullingthe shift lever toward you andmoving it up as far as it will go.

3. Be sure the transfer case is in adrive gear— not in N (Neutral).

4. Turn the ignition key toLOCK/OFF.

5. Remove the key and take it withyou. If you can leave the vehiclewith the ignition key in yourhand, the vehicle is in P (Park).



Leaving the Vehicle With theEngine Running

{ WARNING

It can be dangerous to leave thevehicle with the engine running.The vehicle could move suddenlyif the shift lever is not fully inP (Park) with the parking brakefirmly set.

If you have four-wheel drive andthe transfer case is in N (Neutral),the vehicle will be free to roll,even if the shift lever is inP (Park). So be sure the transfercase is in a drive gear — not inN (Neutral).

(Continued)

WARNING (Continued)

And, if you leave the vehiclewith the engine running, it couldoverheat and even catch fire.You or others could be injured.Do not leave the vehicle withthe engine running unless youhave to.

If you have to leave the vehiclewith the engine running, be sureyour vehicle is in P (Park) and theparking brake is firmly set beforeyou leave it. After you move the shiftlever into P (Park), hold the regularbrake pedal down. Then, see if youcan move the shift lever away fromP (Park) without first pulling it towardyou. If you can, it means that theshift lever was not fully locked intoP (Park).

Torque Lock

If you are parking on a hill andyou do not shift your transmissioninto P (Park) properly, the weightof the vehicle may put too muchforce on the parking pawl in thetransmission. You may find it difficultto pull the shift lever out of P (Park).This is called torque lock. Toprevent torque lock, set the parkingbrake and then shift into P (Park)properly before you leave the driverseat. To find out how, Shifting IntoPark on page 9‑41.

When you are ready to drive, movethe shift lever out of P (Park) beforeyou release the parking brake.

If torque lock does occur, you mayneed to have another vehicle pushyours a little uphill to take some ofthe pressure from the parking pawlin the transmission, then you will beable to pull the shift lever out ofP (Park).



Shifting Out of ParkThis vehicle is equipped withan electronic shift lock releasesystem. The shift lock release isdesigned to:. Prevent ignition key removal

unless the shift lever is inP (Park) with the shift leverbutton fully released.

. Prevent movement of the shiftlever out of P (Park), unlessthe ignition is in ON/RUN orACC/ACCESSORY and theregular brake pedal is applied.

The shift lock release is alwaysfunctional except in the case of anuncharged or low voltage (less than9 volt) battery.

If the vehicle has an unchargedbattery or a battery with low voltage,try charging or jump starting thebattery. See Jump Starting onpage 10‑98 for more information.

To shift out of P (Park) use thefollowing:

1. Apply the brake pedal.

2. Move the shift lever to thedesired position.

If you still are unable to shift out ofP (Park):

1. Ease the pressure on the shiftlever.

2. While holding down the brakepedal, press the shift lever allthe way into P (Park).

3. Move the shift lever to thedesired position.

If you are still having a problemshifting, then have the vehicleserviced soon.

Parking Over ThingsThat Burn

{ WARNING

Things that can burn could touchhot exhaust parts under thevehicle and ignite. Do not parkover papers, leaves, dry grass,or other things that can burn.



Active Fuel Management®

Vehicles with V8 engines mayhave Active Fuel Management™.This system allows the engine tooperate on either all or half of itscylinders, depending on the drivingconditions.

When less power is required, suchas cruising at a constant vehiclespeed, the system will operate inthe half cylinder mode, allowingthe vehicle to achieve better fueleconomy. When greater powerdemands are required, such asaccelerating from a stop, passing,or merging onto a freeway, thesystem will maintain full-cylinderoperation.

If the vehicle has an ActiveFuel Management™ indicator, seeDriver Information Center (DIC) onpage 5‑33 for more information onusing this display.

Engine Exhaust

{ WARNING

Engine exhaust contains CarbonMonoxide (CO) which cannot beseen or smelled. Exposure to COcan cause unconsciousness andeven death.

Exhaust may enter the vehicle if:. The vehicle idles in areaswith poor ventilation (parkinggarages, tunnels, deep snowthat may block underbodyairflow or tail pipes).

. The exhaust smells orsounds strange or different.

. The exhaust system leaksdue to corrosion or damage.

. The vehicle exhaust systemhas been modified, damagedor improperly repaired.

(Continued)

WARNING (Continued)

. There are holes or openingsin the vehicle body fromdamage or after-marketmodifications that are notcompletely sealed.

If unusual fumes are detected orif it is suspected that exhaust iscoming into the vehicle:

. Drive it only with the windowscompletely down.

. Have the vehicle repairedimmediately.

Never park the vehicle with theengine running in an enclosedarea such as a garage or abuilding that has no fresh airventilation.



Running the VehicleWhile ParkedIt is better not to park with theengine running. But if you ever haveto, here are some things to know.

{ WARNING

Idling a vehicle in an enclosedarea with poor ventilation isdangerous. Engine exhaust mayenter the vehicle. Engine exhaustcontains Carbon Monoxide (CO)which cannot be seen or smelled.It can cause unconsciousnessand even death. Never run theengine in an enclosed areathat has no fresh air ventilation.For more information, see EngineExhaust on page 9‑44.

{ WARNING

It can be dangerous to get outof the vehicle if the automatictransmission shift lever is not fullyin P (Park) with the parking brakefirmly set. The vehicle can roll.Do not leave the vehicle whenthe engine is running unlessyou have to. If you have left theengine running, the vehicle canmove suddenly. You or otherscould be injured. To be sure thevehicle will not move, even whenyou are on fairly level ground,always set the parking brake andmove the shift lever to P (Park).

{ WARNING

Four-wheel drive vehicles with thetransfer case in N (Neutral) willallow the vehicle to roll, even ifthe automatic transmission shiftlever is in P (Park). So, be surethe transfer case is in a drivegear — not in N (Neutral). Alwaysset the parking brake.

Follow the proper steps to besure the vehicle will not move.See Shifting Into Park onpage 9‑41.

If pulling a trailer, see DrivingCharacteristics and Towing Tips onpage 9‑91.



AutomaticTransmissionIf the vehicle is a hybrid, seethe hybrid supplement for moreinformation.

Vehicles with an automatictransmission have an electronicshift position indicator withinthe instrument panel cluster.This display comes on whenthe ignition key is turned tothe ON/RUN position.

There are several different positionsfor the shift lever.

Hydra-Matic® 4-Speed AutomaticTransmission

Heavy Duty 6-SpeedAutomatic Transmission Shown(Light Duty 6‐Speed Similar)

See “Range Selection Mode” underManual Mode on page 9‑50.

P (Park): This position locks therear wheels. It is the best positionto use when starting the enginebecause the vehicle cannot moveeasily. When parked on a hill,especially when the vehicle has aheavy load, you might notice anincrease in the effort to shift out ofP (Park). See “Torque Lock” underShifting Into Park on page 9‑41 formore information.

{ WARNING

It is dangerous to get out of thevehicle if the shift lever is not fullyin P (Park) with the parking brakefirmly set. The vehicle can roll.

Do not leave the vehicle whenthe engine is running unlessyou have to. If you have left theengine running, the vehicle canmove suddenly. You or others

(Continued)



WARNING (Continued)

could be injured. To be sure thevehicle will not move, even whenyou are on fairly level ground,always set the parking brake andmove the shift lever to P (Park).See Shifting Into Park onpage 9‑41. If you are pulling atrailer, see Driving Characteristicsand Towing Tips on page 9‑91.

{ WARNING

If you have Four-Wheel Drive, thevehicle will be free to roll— evenif the shift lever is in P (Park)— ifthe transfer case is in Neutral.So, be sure the transfer case isin a drive gear, Two-Wheel DriveHigh or Four-Wheel Drive High orFour-Wheel Drive Low— not inNeutral. See Shifting Into Parkon page 9‑41.

R (Reverse): Use this gear toback up.

Notice: Shifting to R (Reverse)while the vehicle is movingforward could damage thetransmission. The repairs wouldnot be covered by the vehiclewarranty. Shift to R (Reverse)only after the vehicle is stopped.

To rock the vehicle back and forth toget out of snow, ice, or sand withoutdamaging the transmission, see Ifthe Vehicle is Stuck on page 9‑23.

N (Neutral): In this position, theengine does not connect with thewheels. To restart when you arealready moving, use N (Neutral)only. Also, use N (Neutral) whenthe vehicle is being towed.

{ WARNING

Shifting into a drive gear while theengine is running at high speed isdangerous. Unless your foot isfirmly on the brake pedal, thevehicle could move very rapidly.You could lose control and hitpeople or objects. Do not shiftinto a drive gear while the engineis running at high speed.

Notice: Shifting out of P (Park)or N (Neutral) with the enginerunning at high speed maydamage the transmission.The repairs would not be coveredby the vehicle warranty. Be surethe engine is not running at highspeed when shifting the vehicle.



D (Drive): This position is fornormal driving. It provides the bestfuel economy. If you need morepower for passing, and you are:. Going less than about 55 km/h

(35 mph), push the acceleratorpedal about halfway down.

. Going about 55 km/h (35 mph) ormore, push the accelerator allthe way down.

By doing this, the vehicle shiftsdown to the next gear and hasmore power.

D (Drive) can be used when towinga trailer, carrying a heavy load,driving on steep hills, or for off-roaddriving. You might want to shiftthe transmission to a lower gearselection if the transmission shiftstoo often.

Downshifting the transmission inslippery road conditions could resultin skidding. See “Skidding” underLoss of Control on page 9‑6.

The vehicle has a shift stabilizationfeature that adjusts the transmissionshifting to the current drivingconditions in order to reduce rapidupshifts and downshifts. This shiftstabilization feature is designedto determine, before making anupshift, if the engine is able tomaintain vehicle speed by analyzingthings such as vehicle speed,throttle position, and vehicle load.If the shift stabilization featuredetermines that a current vehiclespeed cannot be maintained, thetransmission does not upshift andinstead holds the current gear.In some cases, this could appearto be a delayed shift, however thetransmission is operating normally.

The transmission usesadaptive shift controls.Adaptive shift controls continuallycompares key shift parameters topre-programmed ideal shifts storedin the transmissions computer.The transmission constantly makesadjustments to improve vehicleperformance according to how thevehicle is being used, such as witha heavy load or when temperaturechanges. During this adaptive shiftcontrol process, shifting might feeldifferent as the transmissiondetermines the best settings.

When temperatures are very cold,the Allison Transmission andHydra-Matic 6-Speed transmission'sgear shifting could be delayedproviding more stable shifts untilthe engine warms up. Shifts couldbe more noticeable with a coldtransmission. This difference inshifting is normal.



M (Manual Mode): This positionis available on vehicles with theAllison Transmission or Hydra-Matic6-Speed transmission. It letsdrivers select the range of gearsappropriate for current drivingconditions. If the vehicle has thisfeature, see “Range SelectionMode” under Manual Mode onpage 9‑50.

3 (Third): This position is also usedfor normal driving. It reduces vehiclespeed more than D (Drive) withoutusing the brakes. You might choose3 (Third) instead of D (Drive) whendriving on hilly, winding roads, whentowing a trailer, so there is lessshifting between gears and whengoing down a steep hill.

2 (Second): This position reducesvehicle speed even more than3 (Third) without using the brakes.You can use 2 (Second) on hills.

It can help control vehicle speed asyou go down steep mountain roads,but then you would also want to usethe brakes off and on.

If you manually select 2 (Second)in an automatic transmission, thetransmission will start in secondgear. You can use this feature forreducing the speed of the rearwheels when you are trying tostart the vehicle from a stop onslippery road surfaces.

1 (First): For the Hydra-Matic4-Speed transmission this positionreduces vehicle speed even morethan 2 (Second) without using thebrakes. You can use it on very steephills, or in deep snow or mud. If theshift lever is put in 1 (First) whilethe vehicle is moving forward, thetransmission does not shift into firstgear until the vehicle is going slowlyenough.

For an Allison Transmission orHydra-Matic 6-Speed transmission,this position reduces vehicle speedwithout using the brakes. You canuse it for major/severe downgradesand off-road driving where thevehicle would otherwise acceleratedue to steepness of grade. Whenyou shift to 1 (First) it provides thelowest gear appropriate to currentroad speed and continues todownshift as the vehicle slows,eventually downshifting to1 (First) gear.

Notice: Spinning the tires orholding the vehicle in oneplace on a hill using only theaccelerator pedal may damagethe transmission. The repair willnot be covered by the vehiclewarranty. If you are stuck, do notspin the tires. When stopping ona hill, use the brakes to hold thevehicle in place.



Manual Mode

Range Selection Mode(Allison® Transmission orHydra-Matic® 6-SpeedTransmission)

The vehicle may have a RangeSelection Mode. The RangeSelection Mode helps controlthe vehicle's transmission andvehicle speed while driving downhill or towing a trailer by letting youselect a desired range of gears.

To use this feature, do the following:

1. Move the shift lever toM (Manual Mode).

2. Press the plus/minus buttons,located on the steering columnshift lever, to select the desiredrange of gears for current drivingconditions.

When M (Manual Mode) is selecteda number displays next to the M,indicating the current gear.

This number is the highest gearthat can be used. However, thevehicle can automatically shift tolower gears as it adjusts to drivingconditions. This means that allgears below that number areavailable. When 5 (Fifth) is selected,1 (First) through 5 (Fifth) gears areautomatically shifted by the vehicle,but 6 (Sixth) cannot be used untilthe plus/minus button located onthe steering column lever is usedto change to the gear.

Grade Braking is not available whenRange Selection Mode is active.See Tow/Haul Mode on page 9‑51.

While using Range Selection Mode,Cruise Control and the Tow/HaulMode can be used.

If the vehicle has an exhaustbrake, it can also be used, but willnot automatically downshift thetransmission. See Exhaust Brake inthe Duramax Diesel supplement.

Notice: Spinning the tires orholding the vehicle in oneplace on a hill using only theaccelerator pedal may damagethe transmission. The repair willnot be covered by the vehiclewarranty. If you are stuck, do notspin the tires. When stopping ona hill, use the brakes to hold thevehicle in place.



Low Traction Mode

If your vehicle has the AllisonTransmission, or the Hydra-Matic6-Speed Automatic Transmission,it has a Low Traction Mode thatcan assist in vehicle accelerationwhen road conditions are slippery,such as with ice or snow. Whilethe vehicle is at a stop, select thesecond gear range using RangeSelection Mode. This will limittorque to the wheels after it detectswheel slip, preventing the tires fromspinning.

Tow/Haul Mode

Vehicles with an automatictransmission have a Tow/HaulMode. The Tow/Haul Mode adjuststhe transmission shift pattern toreduce shift cycling, providingincreased performance, vehiclecontrol, and transmission coolingwhen towing or hauling heavy loads.

The selector button is located onthe end of the shift lever. Turnthe Tow/Haul Mode on and offby pressing the button. Whenthe tow/haul is on, a light on theinstrument panel cluster willcome on.

See Tow/Haul Mode Light onpage 5‑29 for more information.

Also see “Tow/Haul Mode” underTowing Equipment on page 9‑112for more information.



Tow/Haul Mode(Allison Transmissionor Hydra-Matic 6-SpeedAutomatic Transmission)

Vehicles with an AllisonTransmission or Hydra-Matic6-Speed Automatic Transmissionhave a Tow/Haul Mode. The Tow/Haul Mode adjusts the transmissionshift pattern to reduce shift cycling,providing increased performance,vehicle control, and transmissioncooling when towing or haulingheavy loads.

Turn the Tow/Haul Mode on andoff by pressing the button, locatedon the end of the shift lever. Whenthe tow/haul is on, a light on theinstrument panel cluster willcome on.

Grade Braking(Allison Transmissionor Hydra-Matic 6-SpeedAutomatic Transmission)

The Grade Braking shift modescan be activated by pressing thebutton on the end of the shift controllever. While in Range SelectionMode, Grade Braking is deactivatedallowing the driver to select adesired range of gears.

Grade Braking is only active whilethe Tow/Haul Mode is selected andyou are not in the Range SelectionMode. See “Tow/Haul Mode” listedpreviously and Manual Mode onpage 9‑50 for more informationon the Range Selection Mode.



Grade Braking assists inmaintaining desired vehiclespeeds when driving ondownhill grades by automaticallyimplementing a shift schedule thatutilizes the engine and transmissionto slow the vehicle. This reduceswear on the braking system andincreases control of the vehicle.Grade Braking monitors vehiclespeed, acceleration, engine torqueand brake pedal usage. Using thisinformation, it detects when thetruck is on a downhill grade andthe driver desires to slow thevehicle by pressing the brake.

This feature is active whenthe exhaust brake is enabled(if equipped).

Also see Towing Equipment onpage 9‑112 for more information.

Cruise Grade Braking(Allison Transmissionor Hydra-Matic 6-SpeedAutomatic Transmission)

Cruise Grade Braking assistswhen driving on a downhill grade.It maintains vehicle speed byautomatically implementing a shiftschedule that uses the engineand the transmission to slow thevehicle. Cruise Grade Brakingoperates while Cruise Control isengaged in Tow/Haul Mode to assistin maintaining vehicle speed underloaded vehicle conditions. It utilizesvehicle acceleration and deviationfrom desired speed to determine

the correct gear for the operatingcondition. If vehicle speed is abovethe desired speed the transmissionwill downshift to slow the vehicle.If vehicle speed is near or belowdesired speed the trans will upshift,allowing vehicle speed to increase.

While in the Range Selection Mode,Cruise Grade Braking is notavailable.

This feature is active whenthe exhaust brake is enabled(if equipped).

See “Range Selection Mode” underManual Mode on page 9‑50.



Drive Systems

Four-Wheel DriveIf the vehicle has Four-WheelDrive, you can send the engine'sdriving power to all four wheelsfor extra traction. To get the mostsatisfaction out of Four-WheelDrive, you must be familiar with itsoperation. Read the following beforeusing Four-Wheel Drive. See theappropriate text for the transfercase in the vehicle.

Notice: Driving on clean, drypavement in Four-Wheel DriveHigh or Four-Wheel Drive Low foran extended period of time maycause premature wear on thevehicle's powertrain. Do notdrive on clean, dry pavementin Four-Wheel Drive High orFour-Wheel Drive Low forextended periods of time.

A parking brake symbol is locatednext to the N (Neutral) symbol as areminder to set the parking brakebefore shifting the transfer case intoN (Neutral).

{ WARNING

Shifting the transfer case toN (Neutral) can cause the vehicleto roll even if the transmissionis in P (Park). You or someoneelse could be seriously injured.Be sure to set the parking brakebefore placing the transfer casein N (Neutral). See Parking Brakeon page 9‑69.

N (Neutral): Shift to this settingonly when the vehicle needs to betowed. See Recreational VehicleTowing on page 10‑103 or Towingthe Vehicle on page 10‑103.

2 m (Two-Wheel Drive High): Thissetting is used for driving in moststreet and highway situations.The front axle is not engaged intwo-wheel drive. This setting alsoprovides the best fuel economy.

4 m (Four-Wheel Drive High): Usethis setting when you need extratraction, such as on snowy or icyroads or in most off-road situations.This setting also engages the frontaxle to help drive your vehicle.This is the best setting to usewhen plowing snow.

You can shift from Two-Wheel DriveHigh to Four-Wheel Drive Highor Four-Wheel Drive High toTwo-Wheel Drive High while thevehicle is moving. In extremelycold weather, it may be necessaryto stop or slow the vehicle to shiftinto Four-Wheel Drive High.



When Using the ManualTransfer Case. Shifts into or out of Four-Wheel

Drive Low or N (Neutral) shouldbe made using quick motions toavoid excessive gear grinding.Shifting slowly may make it moredifficult to shift.

. You may notice that it is harderto shift when the vehicle is cold.After the vehicle warms up theshifting will return to normal.

. While in Four-Wheel High orFour-Wheel Drive Low youmay experience reduced fueleconomy.

. Avoid driving in Four-WheelDrive on clean, dry pavement.It may cause your tires to wearfaster, make the transfer caseharder to shift, and run noisier.

. If the transfer case shifter is inthe N (Neutral) position andyou have difficulty reaching theselected transfer case mode,with the engine running, shiftthe transmission momentarilyto D (Drive) and then back toN (Neutral). This will realign thegear teeth in the transfer caseand allow you to complete theshift.

Shifting from Two-Wheel DriveHigh to Four-Wheel Drive High. Shifts between Two-Wheel Drive

High and Four-Wheel Drive Highcan be made at any vehiclespeed.

. Shift the transfer case lever inone continuous motion intoeither the Four-Wheel DriveHigh or Two-Wheel DriveHigh position.

. Shifting from Two-Wheel DriveHigh to Four-Wheel Drive Highwhile the vehicle is in motionmay require that moderate forcebe applied to the shift lever for afew seconds before Four-WheelDrive High can be engaged,especially in cold weather.

. In extremely cold weather, it maybe necessary to slow or stop thevehicle to shift into Four-WheelDrive High.

. While in Four-Wheel Drive High,the vehicle can be driven at anyposted legal speed limit.



Shifting In or Out of Four-WheelDrive Low

Notice: Shifting the transfercase into Four-Wheel-Drive Lowwhile moving at speeds fasterthan 5 km/h (3 mph) may causepremature wear to the transfercase, and may cause the gearsto grind. To avoid causingpremature wear, and grinding thegears, do not shift the transfercase into Four-Wheel-Drive Lowwhile the vehicle is moving fasterthan 5 km/h (3 mph).. Shifting into Four-Wheel Drive

Low should be done, if possible,with the vehicle at a slight roll,5 km/h (3 mph) or less.

. Shift the transmission intoN (Neutral).

{ WARNING

Shifting the transfer case toN (Neutral) can cause the vehicleto roll even if the transmissionis in P (Park). You or someoneelse could be seriously injured.Be sure to set the parking brakebefore placing the transfer case inN (Neutral). See Parking Brake onpage 9‑69.

. Shifting into Four-Wheel DriveLow with the vehicle at a stopmay be more difficult. You maybe unable to complete the shiftto Four-Wheel Drive Low, andthe transfer case will end up inN (Neutral). This is normal, andis a function of the gear teethaligning in the transfer case.When this happens, makesure the engine is on, shiftthe transmission momentarilyto D (Drive) and back toN (Neutral), and then completethe transfer case shift.

. Shift the transfer case shift leverin one continuous motion intothe Four-Wheel Drive Lowposition.

. When in Four-Wheel DriveLow do not drive faster than72 km/h (45 mph). This willreduce wear and extend thelife of your transfer case.

Shifting In or Out of Neutral

1. With the vehicle running and theengine at an idle, set the parkingbrake.

2. Place the transmission intoN (Neutral).

Shift the transfer case in onecontinuous motion into or out of theN (Neutral) position.

Brakes

Antilock BrakeSystem (ABS)This vehicle has the AntilockBrake System (ABS), an advancedelectronic braking system that helpsprevent a braking skid.

When the engine is started and thevehicle begins to drive away, ABSchecks itself. A momentary motoror clicking noise might be heardwhile this test is going on, andit might even be noticed thatthe brake pedal moves a little.This is normal.

If there is a problem with ABS, thiswarning light stays on. See AntilockBrake System (ABS) Warning Lighton page 5‑28.

If driving safely on a wet roadand it becomes necessary toslam on the brakes and continuebraking to avoid a sudden obstacle,a computer senses that the wheelsare slowing down. If one of thewheels is about to stop rolling,the computer will separatelywork the brakes at each wheel.

ABS can change the brake pressureto each wheel, as required, fasterthan any driver could. This can helpthe driver steer around the obstaclewhile braking hard.

As the brakes are applied, thecomputer keeps receiving updateson wheel speed and controlsbraking pressure accordingly.

Remember: ABS does not changethe time needed to get a foot up tothe brake pedal or always decreasestopping distance. If you get tooclose to the vehicle in front of you,there will not be enough time toapply the brakes if that vehiclesuddenly slows or stops. Alwaysleave enough room up ahead tostop, even with ABS.

Using ABS

Do not pump the brakes. Just holdthe brake pedal down firmly and letABS work. You might hear the ABSpump or motor operating and feelthe brake pedal pulsate, but this isnormal.



Braking in Emergencies

ABS allows the driver to steer andbrake at the same time. In manyemergencies, steering can helpmore than even the very bestbraking.

Parking Brake

Set the parking brake by holdingthe regular brake pedal down, thenpushing down the parking brakepedal.

If the ignition is on, the brakesystem warning light will come on.See Brake System Warning Light onpage 5‑27.

Notice: Driving with the parkingbrake on can overheat the brakesystem and cause prematurewear or damage to brake systemparts. Make sure that the parkingbrake is fully released and thebrake warning light is off beforedriving.

To release the parking brake, holdthe regular brake pedal down, thenpush down momentarily on theparking brake pedal until you feelthe pedal release. Slowly pull yourfoot up off the parking brake pedal.If the parking brake is not releasedwhen you begin to drive, the brakesystem warning light will flash and achime will sound warning you thatthe parking brake is still on.

If you are towing a trailer andare parking on a hill, see DrivingCharacteristics and Towing Tips onpage 9‑91.

Brake Assist (ExceptWith 4.3L V6 Engine)If this vehicle has StabiliTrak®, italso has a Brake Assist featuredesigned to assist the driver instopping or decreasing vehiclespeed in emergency drivingconditions. This feature uses thestability system hydraulic brakecontrol module to supplementthe power brake system underconditions where the driver hasquickly and forcefully applied thebrake pedal in an attempt to quicklystop or slow down the vehicle.The stability system hydraulic brakecontrol module increases brakepressure at each corner of thevehicle until the ABS activates.



Minor brake pedal pulsation orpedal movement during this timeis normal and the driver shouldcontinue to apply the brake pedalas the driving situation dictatesThe Brake Assist feature willautomatically disengage whenthe brake pedal is released orbrake pedal pressure is quicklydecreased.

Hill Start Assist (HSA)2500 and 3500 series vehicles withStabiliTrak have a Hill Start Assist(HSA) feature, which may be usefulwhen the vehicle is stopped on agrade. This feature is designed toprevent the vehicle from rolling,either forward or rearward, duringvehicle drive off. After the drivercompletely stops and holds thevehicle in a complete standstill ona grade, HSA will be automatically

activated. During the transitionperiod between when the driverreleases the brake pedal and startsto accelerate to drive off on a grade,HSA holds the braking pressurefor a maximum of two secondsto ensure that there is no rolling.The brakes will automaticallyrelease when the accelerator pedalis applied within the two‐secondwindow. If the vehicle is equippedwith the Integrated Trailer BrakeControl (ITBC) system, HSA mayalso apply the trailer brakes. It willnot activate if the vehicle is in adrive gear and facing downhill orif the vehicle is facing uphill andin R (Reverse). There may besituations on minor hills (less than5% grade) with a loaded vehicle orwhile pulling a trailer where HSAwill not activate.

Ride Control Systems

StabiliTrak® SystemThe vehicle may have a vehiclestability enhancement system calledStabiliTrak®. It is an advancedcomputer-controlled system thatassists the driver with directionalcontrol of the vehicle in difficultdriving conditions.

StabiliTrak activates when thecomputer senses a discrepancybetween the intended path andthe direction the vehicle is actuallytraveling. StabiliTrak selectivelyapplies braking pressure at any oneof the vehicle's brakes to assist thedriver with keeping the vehicle onthe intended path.



When the vehicle is startedand begins to move, the systemperforms several diagnostic checksto insure there are no problems.The system may be heard orfelt while it is working. This isnormal and does not mean thereis a problem with the vehicle.The system should initializebefore the vehicle reaches 32 km/h(20 mph). In some cases, it maytake approximately 3.2 km (2 mi) ofdriving before the system initializes.

If cruise control is being used whenStabiliTrak activates, the cruisecontrol automatically disengages.The cruise control can bere-engaged when road conditionsallow. See Cruise Control onpage 9‑73 for more information.

If the system fails to turn on oractivate, the StabiliTrak lightalong with one of the followingmessages will be displayedon the Driver InformationCenter (DIC): TRACTION

CONTROL OFF, SERVICETRACTION CONTROL,STABILITRAK OFF, SERVICESTABILITRAK. If these DICmessages appear, make sure theStabiliTrak system has not beenturned off using the StabiliTrakon/off button. Then turn the vehicleoff, wait 15 seconds, and turn itback on again to reset the system.If any of these messages stillappear on the DIC, the vehicleshould be taken in for service.For more information on the DICmessages, see Ride ControlSystem Messages on page 5‑47.

The StabiliTrak light will flash on theinstrument panel cluster when thesystem is both on and activated.

The system may be heard or feltwhile it is working; this is normal.

The traction control disable buttonis located on the instrument panelbelow the climate controls.

The Traction Control System (TCS)part of StabiliTrak can be turnedoff by pressing and releasing theStabiliTrak button. To disable bothTCS and StabiliTrak, press andhold 5 until F illuminates and theappropriate DIC message displays.

TCS and StabiliTrak can be turnedon by pressing and releasing theStabiliTrak button if they are notautomatically shut off for any otherreason.



When TCS or StabiliTrak isturned off, the StabiliTrak lightand the appropriate messagewill be displayed on the DIC towarn the driver. The vehicle willstill have brake-traction controlwhen traction control is off, but willnot be able to use the engine speedmanagement system. See “TractionControl Operation” next for moreinformation.

When the traction control systemhas been turned off, system noisesmay still be heard as a result of thebrake-traction control coming on.

It is recommended to leave thesystem on for normal drivingconditions, but it may be necessaryto turn the system off if the vehicleis stuck in sand, mud, ice or snow,and you want to “rock” the vehicleto attempt to free it. It may also benecessary to turn off the systemwhen driving in extreme off-roadconditions where high wheel spinis required. See If the Vehicle isStuck on page 9‑23.

When the transfer case is in 4LO,the stability system is automaticallydisabled, the StabiliTrak light comeson, and the STABILITRAK OFFmessage will appear on the DIC.Both traction control and StabiliTrakare automatically disabled in thiscondition.

Traction Control Operation

The traction control system is partof the StabiliTrak system. Tractioncontrol limits wheel spin by reducingengine power to the wheels (enginespeed management) and byapplying brakes to each individualwheel (brake-traction control) asnecessary.

The traction control system isenabled automatically when thevehicle is started. It will activateand the StabiliTrak light will flashif it senses that any of the wheelsare spinning or beginning to lose

traction while driving. If tractioncontrol is turned off, only thebrake-traction control portionof traction control will work.The engine speed managementwill be disabled. In this mode,engine power is not reducedautomatically and the drivenwheels can spin more freely.This can cause the brake-tractioncontrol to activate constantly.

Notice: If the wheel(s) of one axleis allowed to spin excessivelywhile the StabiliTrak®, ABS, brakewarning lights, and any relevantDIC messages are displayed, thetransfer case could be damaged.The repairs would not be coveredby the vehicle warranty. Reduceengine power and do not spinthe wheel(s) excessively whilethese lights and messages aredisplayed.



The traction control system mayactivate on dry or rough roadsor under conditions such asheavy acceleration while turningor abrupt upshifts/downshifts of thetransmission. When this happens,a reduction in acceleration may benoticed, or a noise or vibration maybe heard. This is normal.

If cruise control is being used whenthe system activates, the StabiliTraklight will flash and cruise control willautomatically disengage. Cruisecontrol may be reengaged whenroad conditions allow. See CruiseControl on page 9‑73.

StabiliTrak may also turn offautomatically if it determines thata problem exists with the system.If the problem does not clear itselfafter restarting the vehicle, see yourdealer for service.

2500 and 3500 series vehicleswith StabiliTrak have a Trailer SwayControl (TSC) feature. See TrailerSway Control (TSC) on page 9‑124.

2500 and 3500 series vehicleswith StabiliTrak have a Hill StartAssist (HSA) feature. See Hill StartAssist (HSA) on page 9‑70.

Adding non‐dealer accessories canaffect the vehicle's performance.See Accessories and Modificationson page 10‑3.

Locking Rear AxleVehicles with a locking rear axle cangive more traction on snow, mud,ice, sand, or gravel. It works like astandard axle most of the time, butwhen traction is low, this feature willallow the rear wheel with the mosttraction to move the vehicle.

Cruise Control

{ WARNING

Cruise control can be dangerouswhere you cannot drive safely ata steady speed. So, do not usethe cruise control on windingroads or in heavy traffic.

Cruise control can be dangerouson slippery roads. On such roads,fast changes in tire traction cancause excessive wheel slip, andyou could lose control. Do not usecruise control on slippery roads.

For vehicles with cruise control, aspeed of about 40 km/h (25 mph)or more can be maintainedwithout keeping your foot on theaccelerator. Cruise control doesnot work at speeds below about40 km/h (25 mph).



When the brakes are applied, cruisecontrol is turned off.

For vehicles with an Allison orHydra‐Matic 6‐speed automatictransmission, see “Grade Brakingand Cruise Grade Braking(Allison Transmission) underTow/Haul Mode on page 9‑51for an explanation of how cruisecontrol interacts with the RangeSelection Mode, tow/haul andgrade braking systems.

For vehicles with the StabiliTraksystem that begins to limit wheelspin while you are using cruisecontrol, the cruise control willautomatically disengage. SeeStabiliTrak® System on page 9‑70.When road conditions allow thecruise control to be safely usedagain, it can be turned back on.

The cruise control buttons arelocated on the left side of thesteering wheel.

I (On/Off): Press to turn thesystem on or off. The indicator lightis on when cruise control is on andturns off when cruise control is off.

Reducing Speed While UsingCruise Control

If the cruise control system isalready activated,. Press and hold the SET– button

on the steering wheel until thedesired lower speed is reached,then release it.

. To slow down in small amounts,press the SET– button on thesteering wheel briefly. Each timethis is done, the vehicle goesabout 1.6 km/h (1 mph) slower.

Passing Another Vehicle WhileUsing Cruise Control

Use the accelerator pedal toincrease the vehicle speed. Whenyou take your foot off the pedal,the vehicle will slow down to theprevious set cruise speed.

Using Cruise Control on Hills

How well the cruise control will workon hills depends upon the vehiclespeed, load, and the steepness ofthe hills. While going up steep hills,you might have to step on theaccelerator pedal to maintain thevehicle speed. While going downhill,you might have to brake or shift toa lower gear to keep the vehiclespeed down. When the brakesare applied the cruise control isdisengaged.



Ending Cruise Control

There are three ways to end cruisecontrol:. To disengage cruise control;

step lightly on the brake pedal.

. Press [ on the steering wheel.

. To turn off the cruise control,pressI on the steering wheel.

Erasing Speed Memory

Object DetectionSystems

Ultrasonic Parking AssistFor vehicles with the UltrasonicRear Parking Assist (URPA) system,it operates at speeds less than8 km/h (5 mph), and assists thedriver with parking and avoidingobjects while in R (Reverse).The sensors on the rear bumperare used to detect the distance toan object up to 2.5 m (8 ft) behindthe vehicle, and at least 25.4 cm(10 in) off the ground.

{ WARNING

The Ultrasonic Rear ParkingAssist (URPA) system does notreplace driver vision. It cannotdetect:

. Objects that are below thebumper, underneath thevehicle, or too close or farfrom the vehicle.

. Children, pedestrians,bicyclists, or pets.

If you do not use proper carebefore and while backing, vehicledamage, injury, or death couldoccur. Even with URPA, alwayscheck behind the vehicle beforebacking up. While backing, besure to look for objects and checkthe vehicle's mirrors.



How the System Works

URPA comes on automaticallywhen the shift lever is moved intoR (Reverse). A single tone soundsto indicate the system is working.

URPA operates only at speeds lessthan 8 km/h (5 mph).

An obstacle is indicated by audiblebeeps. The interval between thebeeps becomes shorter as thevehicle gets closer to the obstacle.When the distance is less than30 cm (12 in) the beeps arecontinuous.

To be detected, objects must be atleast 25.4 cm (10 in) off the groundand below tailgate level. Objectsmust also be within 2.5 m (8 ft) fromthe rear bumper. This distance maybe less during warmer or humidweather.

The system can be disabled bypressing the rear park aid disablebutton located next to the radio.

The indicator light comes on andPARK ASSIST OFF displays on theDriver Information Center (DIC) toindicate that URPA is off; see ObjectDetection System Messages onpage 5‑46.

Notice: If you use URPA whilethe tailgate is lowered, it maynot detect an object behind yourvehicle, and you might back intothe object and damage yourvehicle. Always verify the tailgateis closed when using URPA orturn off URPA when driving withthe tailgate lowered.

When the System Does NotSeem to Work Properly

The following messages may bedisplayed on the DIC:

FuelFor diesel engine vehicles, see“Fuel for Diesel Engines” in theDuramax Diesel Supplement.

For Vehicles with gasoline engines,please read this.

Gasoline

Use of the recommended fuelis an important part of the propermaintenance of this vehicle. To helpkeep the engine clean and maintainoptimum vehicle performance, werecommend the use of gasolineadvertised as TOP TIER DetergentGasoline.

Look for the TOP TIER label on thefuel pump to ensure gasoline meetsenhanced detergency standardsdeveloped by auto companies. A listof marketers providing TOP TIERDetergent Gasoline can be foundat www.toptiergas.com.

The eighth digit of the VehicleIdentification Number (VIN) showsthe code letter or number thatidentifies the vehicle's engine.The VIN is at the top left of theinstrument panel. See VehicleIdentification Number (VIN) onpage 12‑1.

Vehicles that have a FlexFuel badgeand a yellow fuel cap can use eitherunleaded gasoline or ethanol fuelcontaining up to 85% ethanol (E85).

See Fuel E85 (85% Ethanol) onpage 9‑87. For all other vehicles,use only the unleaded gasolinedescribed under RecommendedFuel on page 9‑84.

Recommended FuelFor all vehicles except those withthe 6.2L V8 engine (VIN Code 2),use regular unleaded gasolinewith a posted octane rating of 87 orhigher. If the octane rating is lessthan 87, an audible knocking noise,commonly referred to as sparkknock, might be heard when driving.If this occurs, use a gasoline ratedat 87 octane or higher as soonas possible. If heavy knocking isheard when using gasoline ratedat 87 octane or higher, the engineneeds service.



If the vehicle has the 6.2L V8 engine(VIN Code 2), use premiumunleaded gasoline with a postedoctane rating of 91 or higher.You can also use regular unleadedgasoline rated at 87 octane orhigher, but the vehicle's accelerationcould be slightly reduced, anda slight audible knocking noise,commonly referred to as sparkknock, might be heard. If the octaneis less than 87, you might noticea heavy knocking noise when youdrive. If this occurs, use a gasolinerated at 87 octane or higher as soonas possible. Otherwise, you coulddamage the engine. If heavyknocking is heard when usinggasoline rated at 87 octane orhigher, the engine needs service.

Gasoline Specifications(U.S. and Canada Only)At a minimum, gasoline shouldmeet ASTM specificationD 4814 in the United Statesor CAN/CGSB‐3.5 or 3.511 inCanada. Some gasolines containan octane-enhancing additive calledmethylcyclopentadienyl manganesetricarbonyl (MMT). We recommendagainst the use of gasolinescontaining MMT. See Fuel Additiveson page 9‑86 for additionalinformation.

California FuelRequirementsIf the vehicle is certified to meetCalifornia Emissions Standards,it is designed to operate on fuelsthat meet California specifications.See the underhood emission controllabel. If this fuel is not available instates adopting California EmissionsStandards, the vehicle will operatesatisfactorily on fuels meetingfederal specifications, but emissioncontrol system performance mightbe affected. The malfunctionindicator lamp could turn on and thevehicle might fail a smog‐check test.See Malfunction Indicator Lamp onpage 5‑25. If this occurs, return toyour authorized dealer for diagnosis.If it is determined that the conditionis caused by the type of fuel used,repairs might not be covered by thevehicle warranty.



Fuels in ForeignCountriesNever use leaded gasoline or anyother fuel not recommended in theprevious text on fuel. Costly repairscaused by use of improper fuelwould not be covered by the vehiclewarranty.

To check the fuel availability, askan auto club, or contact a major oilcompany that does business in thecountry where you will be driving.

Fuel AdditivesTo provide cleaner air, all gasolinesin the United States are nowrequired to contain additives thathelp prevent engine and fuel systemdeposits from forming, allowing theemission control system to workproperly. In most cases, nothingshould have to be added to the fuel.However, some gasolines containonly the minimum amount of

additive required to meet U.S.Environmental Protection Agencyregulations. To help keep fuelinjectors and intake valves cleanand avoid problems due to dirtyinjectors or valves, look for gasolinethat is advertised as TOP TIERDetergent Gasoline. Look for theTOP TIER label on the fuel pump toensure gasoline meets enhanceddetergency standards developedby the auto companies. A list ofmarketers providing TOP TIERDetergent Gasoline can be foundat www.toptiergas.com.

For customers who do not useTOP TIER Detergent Gasolineregularly, one bottle of GM FuelSystem Treatment PLUS, addedto the fuel tank at every engine oilchange, can help clean depositsfrom fuel injectors and intakevalves. GM Fuel System TreatmentPLUS is the only gasoline additiverecommended by General Motors.It is available at your dealer.

Gasolines containing oxygenates,such as ethers and ethanol,and reformulated gasolinesmight be available in your area.We recommend that you use thesegasolines, if they comply with thespecifications described earlier.However, E85 (85% ethanol) andother fuels containing more than10% ethanol must not be used invehicles that were not designedfor those fuels.

Notice: This vehicle was notdesigned for fuel that containsmethanol. Do not use fuelcontaining methanol. It cancorrode metal parts in the fuelsystem and also damage plasticand rubber parts. That damagewould not be covered under thevehicle warranty.



Some gasolines that arenot reformulated for lowemissions can contain anoctane-enhancing additivecalled methylcyclopentadienylmanganese tricarbonyl (MMT);ask the attendant where you buygasoline whether the fuel containsMMT. We recommend againstthe use of such gasolines. Fuelscontaining MMT can reducespark plug life and affect emissioncontrol system performance.The malfunction indicator lampmight turn on. If this occurs,return to your dealer for service.

Fuel E85 (85% Ethanol)Vehicles that have a FlexFuel badgeand a yellow fuel cap can use eitherunleaded gasoline or ethanol fuelcontaining up to 85% ethanol (E85).For all other vehicles, use only theunleaded gasoline described underRecommended Fuel on page 9‑84.

We encourage the use of E85 invehicles that are designed to use it.The ethanol in E85 is a “renewable”fuel, meaning it is made fromrenewable sources such as cornand other crops.

Many service stations will not havean 85% ethanol fuel (E85) pumpavailable. The U.S. Departmentof Energy has an alternative fuelswebsite (www.afdc.energy.gov/afdc/locator/stations/) that can help youfind E85 fuel. Those stations thatdo have E85 should have a labelindicating ethanol content. Do notuse the fuel if the ethanol content isgreater than 85%.

At a minimum, E85 should meetASTM Specification D 5798.By definition, this means that fuellabeled E85 will have an ethanolcontent between 70% and 85%.Filling the fuel tank with fuelmixtures that do not meet ASTMspecifications can affect driveabilityand could cause the malfunctionindicator lamp to come on.

To ensure quick starts in thewintertime, the E85 fuel must beformulated properly for your climateaccording to ASTM specificationD 5798. If you have trouble startingon E85, it could be because theE85 fuel is not properly formulatedfor your climate. If this happens,switching to gasoline or addinggasoline to the fuel tank canimprove starting. For good startingand heater efficiency below 0°C(32°F), the fuel mix in the fuel tankshould contain no more than 70%ethanol. It is best not to alternaterepeatedly between gasoline andE85. If you do switch fuels, it isrecommended that you add asmuch fuel as possible — do notadd less than 11 L (3 gal) whenrefueling. You should drive thevehicle immediately after refuelingfor at least 11 km (7 mi) to allowthe vehicle to adapt to the changein ethanol concentration.



E85 has less energy per liter(gallon) than gasoline, so you willneed to refill the fuel tank moreoften when using E85 than whenyou are using gasoline. See Fillingthe Tank on page 9‑88.

Notice: Some additives are notcompatible with E85 fuel and canharm the vehicle's fuel system.Do not add anything to E85.Damage caused by additiveswould not be covered by thevehicle warranty.

Notice: This vehicle was notdesigned for fuel that containsmethanol. Do not use fuelcontaining methanol. It cancorrode metal parts in the fuelsystem and also damage plasticand rubber parts. That damagewould not be covered under thevehicle warranty.

Filling the TankIf the vehicle has a diesel engine,see the Duramax diesel supplementfor more information.

{ WARNING

Fuel vapor burns violently and afuel fire can cause bad injuries.To help avoid injuries to you andothers, read and follow all theinstructions on the fuel pumpisland. Turn off the engine whenrefueling. Do not smoke near fuelor when refueling the vehicle.Do not use cellular phones. Keepsparks, flames, and smokingmaterials away from fuel. Do notleave the fuel pump unattendedwhen refueling the vehicle. This isagainst the law in some places.Do not re-enter the vehicle whilepumping fuel. Keep children awayfrom the fuel pump; never letchildren pump fuel.

The tethered fuel cap is locatedbehind a hinged fuel door on thedriver side of the vehicle. Vehiclesthat have a FlexFuel badge anda yellow fuel cap can use eitherunleaded gasoline or ethanol fuelcontaining up to 85% ethanol (E85).See Fuel E85 (85% Ethanol) onpage 9‑87.

To remove the fuel cap, turn itslowly counterclockwise.



{ WARNING

Fuel can spray out on you if youopen the fuel cap too quickly.If you spill fuel and thensomething ignites it, you could bebadly burned. This spray canhappen if the tank is nearly full,and is more likely in hot weather.Open the fuel cap slowly and waitfor any hiss noise to stop. Thenunscrew the cap all the way.

If the vehicle is a dual fuel tankchassis cab model, and it runs outof fuel, refuel the front fuel tank firstto ensure a quick restart.

Be careful not to spill fuel. Do nottop off or overfill the tank and wait afew seconds after you have finished

pumping before removing thenozzle. Clean fuel from paintedsurfaces as soon as possible.See Exterior Care on page 10‑108.

When replacing the fuel cap, turn itclockwise until it clicks. It will requiremore effort to turn the fuel cap onthe last turn as you tighten it. Makesure the cap is fully installed. Thediagnostic system can determine ifthe fuel cap has been left off orimproperly installed. This wouldallow fuel to evaporate into theatmosphere. See MalfunctionIndicator Lamp on page 5‑25.

The TIGHTEN GAS CAP messagedisplays on the Driver InformationCenter (DIC) if the fuel cap is notproperly installed. See Fuel SystemMessages on page 5‑46 for moreinformation.

{ WARNING

If a fire starts while you arerefueling, do not remove thenozzle. Shut off the flow of fuelby shutting off the pump or bynotifying the station attendant.Leave the area immediately.

Notice: If a new fuel cap isneeded, be sure to get the righttype of cap from your dealer.The wrong type of fuel cap mightnot fit properly, might cause themalfunction indicator lamp tolight, and could damage thefuel tank and emissions system.See Malfunction Indicator Lampon page 5‑25.



Filling a Portable FuelContainer

{ WARNING

Never fill a portable fuel containerwhile it is in the vehicle. Staticelectricity discharge from thecontainer can ignite the fuelvapor. You can be badly burnedand the vehicle damaged if thisoccurs. To help avoid injury toyou and others:

. Dispense fuel only intoapproved containers.

. Do not fill a container whileit is inside a vehicle, in avehicle's trunk, pickup bed,or on any surface other thanthe ground.

(Continued)

WARNING (Continued)

. Bring the fill nozzle in contactwith the inside of the fillopening before operatingthe nozzle. Contact shouldbe maintained until the fillingis complete.

. Do not smoke whilepumping fuel.

. Do not use a cellular phonewhile pumping fuel.

Towing

General TowingInformationOnly use towing equipment thathas been designed for the vehicle.Contact your dealer or traileringdealer for assistance with preparingthe vehicle for towing a trailer.

See the following trailer towinginformation in this section:. For information on driving

while towing a trailer, see“Driving Characteristics andTowing Tips.”

. For maximum vehicle and trailerweights, see “Trailer Towing.”

. For information on equipmentto tow a trailer, see “TowingEquipment.”



For information on towing a disabledvehicle, see Towing the Vehicle onpage 10‑103. For information ontowing the vehicle behind anothervehicle such as a motor home, seeRecreational Vehicle Towing onpage 10‑103.

Driving Characteristicsand Towing Tips

Pulling a Trailer

Important points for pulling a trailer:. There are many different laws,

including speed limit restrictions,having to do with trailering.Make sure the rig will be legal,not only where you live butalso where you will be driving.A good source for thisinformation can be stateor provincial police.

. Consider using a sway control.See “Hitches” under TowingEquipment on page 9‑112.

. Do not tow a trailer at all duringthe first 800 km (500 miles)the new vehicle is driven.The engine, axle, or otherparts could be damaged.

. During the first 800 km(500 miles) that a trailer istowed, do not drive over80 km/h (50 mph) and donot make starts at full throttle.This helps the engine and otherparts of the vehicle wear in atthe heavier loads.

. Vehicles can tow in D (Drive).Shift the transmission to a lowergear if the transmission shiftstoo often under heavy loadsand/or hilly conditions.

Important considerations that haveto do with weight:. Weight of the trailer. Weight of the trailer tongue. Weight on the vehicle's tires. Weight of the trailering

combination



Driving with a Trailer

{ WARNING

When towing a trailer, exhaustgases may collect at the rearof the vehicle and enter if theliftgate, trunk/hatch, or rear-mostwindow is open.

Engine exhaust contains CarbonMonoxide (CO) which cannot beseen or smelled. It can causeunconsciousness and even death.

To maximize safety when towinga trailer:

. Have the exhaust systeminspected for leaks and makenecessary repairs beforestarting a trip.

. Never drive with the liftgate,trunk/hatch, or rear-mostwindow open.

(Continued)

WARNING (Continued)

. Fully open the air outletson or under the instrumentpanel.

. Adjust the Climate Controlsystem to a setting thatbrings in only outside airand set the fan speed to thehighest setting. See ClimateControl System in the Index.

For more information aboutCarbon Monoxide, see EngineExhaust on page 9‑44.

Towing a trailer requires acertain amount of experience.The combination you are driving islonger and not as responsive as thevehicle itself. Get acquainted withthe handling and braking of the rigbefore setting out for the open road.

Before starting, check all trailerhitch parts and attachments, safetychains, electrical connectors,lamps, tires, and mirrors. If thetrailer has electric brakes, start thecombination moving and then applythe trailer brake controller by handto be sure the brakes work.

During the trip, check occasionallyto be sure that the load is secureand the lamps and any trailerbrakes still work.

Following Distance

Stay at least twice as far behind thevehicle ahead as you would whendriving the vehicle without a trailer.This can help to avoid heavybraking and sudden turns.



Passing

More passing distance isneeded when towing a trailer.The combination will not accelerateas quickly and is longer so it isnecessary to go much fartherbeyond the passed vehicle beforereturning to the lane.

Backing Up

Hold the bottom of the steeringwheel with one hand. To move thetrailer to the left, move that handto the left. To move the trailer tothe right, move your hand to theright. Always back up slowly and,if possible, have someoneguide you.

Making Turns

Notice: Making very sharp turnswhile trailering could cause thetrailer to come in contact withthe vehicle. The vehicle could bedamaged. Avoid making verysharp turns while trailering.

When turning with a trailer,make wider turns than normal.Do this so the trailer will not strikesoft shoulders, curbs, road signs,trees, or other objects. Avoid jerkyor sudden maneuvers. Signal wellin advance.

If the trailer turn signal bulbs burnout, the arrows on the instrumentpanel will still flash for turns. It isimportant to check occasionally tobe sure the trailer bulbs are stillworking.

Driving on Grades

Reduce speed and shift to alower gear before starting downa long or steep downgrade. If thetransmission is not shifted down,the brakes might get hot and nolonger work well.

Vehicles can tow in D (Drive).Shift the transmission to a lowergear if the transmission shifts toooften under heavy loads and/orhilly conditions.

The Tow/Haul Mode may be usedif the transmission shifts too often.See Tow/Haul Mode on page 9‑51.

When towing at high altitude onsteep uphill grades, consider thefollowing: Engine coolant will boilat a lower temperature than atnormal altitudes. If the engine isturned off immediately after towingat high altitude on steep uphillgrades, the vehicle may showsigns similar to engine overheating.



To avoid this, let the enginerun while parked, preferably onlevel ground, with the automatictransmission in P (Park) for a fewminutes before turning the engineoff. If the overheat warning comeson, see Engine Overheating onpage 10‑25.

Parking on Hills

{ WARNING

Parking the vehicle on a hillwith the trailer attached can bedangerous. If something goeswrong, the rig could start to move.People can be injured, and boththe vehicle and the trailer can bedamaged. When possible, alwayspark the rig on a flat surface.

If parking the rig on a hill:

1. Press the brake pedal, butdo not shift into P (Park) yet.Turn the wheels into the curb iffacing downhill or into traffic iffacing uphill.

2. Have someone place chocksunder the trailer wheels.

3. When the wheel chocks are inplace, release the regular brakesuntil the chocks absorb the load.

4. Reapply the brake pedal. Thenapply the parking brake and shiftinto P (Park).

5. If the vehicle is four-wheel-drive,be sure the transfer case is in adrive gear and not in N (Neutral).

6. Release the brake pedal.

{ WARNING

It can be dangerous to get out ofthe vehicle if the shift lever is notfully in P (Park) with the parkingbrake firmly set. The vehiclecan roll.

If the engine has been leftrunning, the vehicle can movesuddenly. You or others could beinjured. To be sure the vehicle willnot move, even when on fairlylevel ground, use the steps thatfollow.

Always put the shift lever fully inP (Park) with the parking brakefirmly set.

If the transfer case on afour-wheel-drive vehicle is inN (Neutral), the vehicle will befree to roll, even if the shift leveris in P (Park). Be sure the transfercase is in a drive gear — not inN (Neutral).



Leaving After Parking on a Hill

1. Apply and hold the brake pedal.2. Start the engine.3. Shift into a gear.4. Release the parking brake.5. Let up on the brake pedal.6. Drive slowly until the trailer is

clear of the chocks.7. Stop and have someone pick up

and store the chocks.

Maintenance when TrailerTowing

The vehicle needs service moreoften when pulling a trailer. See thismanual's Maintenance Scheduleor Index for more information.Things that are especially importantin trailer operation are automatictransmission fluid, engine oil, axlelubricant, belts, cooling system,and brake system. It is a goodidea to inspect these beforeand during the trip.

Check periodically to see that allhitch nuts and bolts are tight.

Trailer TowingIf the vehicle has a diesel engine,see the Duramax diesel supplementfor more information.


Do not tow a trailer during break‐in.See New Vehicle Break-In onpage 9‑34 for more information.

{ WARNING

The driver can lose control whenpulling a trailer if the correctequipment is not used or thevehicle is not driven properly.For example, if the trailer is tooheavy, the brakes may not workwell or even at all. The driver andpassengers could be seriouslyinjured. The vehicle may also bedamaged; the resulting repairswould not be covered by the

WARNING (Continued)

vehicle warranty. Pull a traileronly if all the steps in this sectionhave been followed. Ask yourdealer for advice and informationabout towing a trailer with thevehicle.

Notice: Pulling a trailerimproperly can damage thevehicle and result in costlyrepairs not covered by thevehicle warranty. To pull a trailercorrectly, follow the advice inthis section and see your dealerfor important information abouttowing a trailer with the vehicle.

To identify the trailering capacity ofthe vehicle, read the information in“Weight of the Trailer” later in thissection.



Trailering is different than justdriving the vehicle by itself.Trailering means changes inhandling, acceleration, braking,durability, and fuel economy.Successful, safe trailering takescorrect equipment, and it has tobe used properly.

The following information has manytime-tested, important trailering tipsand safety rules. Many of these areimportant for your safety and that ofyour passengers. So please readthis section carefully before pullinga trailer.

Weight of the Trailer

How heavy can a trailer safely be?

It depends on how the rig is used.Speed, altitude, road grades,outside temperature, and how muchthe vehicle is used to pull a trailerare all important. It can dependon any special equipment on thevehicle, and the amount of tongueweight the vehicle can carry. See“Weight of the Trailer Tongue” laterin this section for more information.

Trailer weight rating (TWR) iscalculated assuming the tow vehiclehas only the driver but all requiredtrailering equipment. Weight ofadditional optional equipment,passengers, and cargo in the towvehicle must be subtracted fromthe trailer weight rating.

Use the following chart to determinehow much the vehicle can weigh,based upon the vehicle model andoptions.

Weights listed apply forconventional trailers and fifth-wheeltrailers unless otherwise noted.

The GCWR for the vehicle should not beexceeded.(b) Fifth-wheel or gooseneck kingpin weight should be 15 percent to 25 percent of trailer weight up to680 kg (1,500 lbs) maximum.(c) This model is neither designed nor intended to tow fifth-wheel or gooseneck trailers.(d) Fifth-wheel or gooseneck kingpin weight should be 15 percent to 25 percent of trailer weight up to1 361 kg (3,000 lbs) maximum.(e) Fifth-wheel or gooseneck kingpin weight should be 15 percent to 25 percent of trailer weight up to1 587 kg (3,500 lbs) maximum.



Ask your dealer for traileringinformation or advice, or write us atour Customer Assistance Offices.See Customer Assistance Offices(U.S. and Canada) on page 13‑5or Customer Assistance Offices(Mexico) on page 13‑5 for moreinformation.

Weight of the Trailer Tongue

The tongue load (A) of anytrailer is very important becauseit is also part of the vehicle weight.The Gross Vehicle Weight (GVW)includes the curb weight of the

vehicle, any cargo carried in it, andthe people who will be riding in thevehicle as well as trailer tongueweight. Vehicle options, equipment,passengers and cargo in the vehiclereduce the amount of tongue weightthe vehicle can carry, which will alsoreduce the trailer weight the vehiclecan tow. See “ Vehicle Load Limits”for more information about thevehicle's maximum load capacity.

Trailer tongue weight (A) should be10 to 15 percent and fifth-wheel orgooseneck kingpin weight should be15 to 25 percent of the loaded trailerweight up to the maximums forvehicle series and hitch typeshown here:



Vehicle Series Hitch TypeMaximum Tongue

Weight

1500 Weight Carrying 272 kg (600 lbs)

2500HD/3500 Weight Carrying 453 kg (1,000 lbs)

1500 Weight Distributing 499 kg (1,100 lbs)

2500HD/3500 Weight Distributing 680 kg (1,500 lbs)

1500 Fifth-Wheel Gooseneck 680 kg (1,500 lbs)

2500HD Fifth-Wheel Gooseneck 1134 kg (2,500 lbs)

3500 Single RearWheels Fifth-Wheel Gooseneck 1 360 kg (3,000 lbs)

3500 Dual RearWheels

Fifth-Wheel Gooseneck 1 587 kg (3,500 lbs)

Do not exceed the maximumallowable tongue weight for thevehicle. Choose the shortest hitchextension that will position the hitchball closest to the vehicle. This willhelp reduce the effect of trailertongue weight on the rear axle.

Trailering may be limited by thevehicle's ability to carry tongueweight. Tongue or kingpin weightcannot cause the vehicle to exceedthe GVWR (Gross Vehicle WeightRating) or the RGAWR (Rear GrossAxle Weight Rating). See “TotalWeight on the Vehicle's Tires” laterin this section for more information.

After loading the trailer, weighthe trailer and then the tongue,separately, to see if the weights areproper. If they are not, adjustmentsmight be made by moving someitems around in the trailer.

Total Weight on the Vehicle'sTires

Be sure the vehicle's tires areinflated to the inflation pressuresfound on the Certification Tire labelon the drivers door or see VehicleLoad Limits on page 9‑25 for moreinformation. Make sure not toexceed the GVWR limit for thevehicle, or the RGAWR, with thetow vehicle and trailer fully loadedfor the trip including the weightof the trailer tongue. If using aweight-distributing hitch, makesure not to exceed the RGAWRbefore applying the weightdistribution spring bars.



Weight of the TraileringCombination

It is important that the combinationof the tow vehicle and trailerdoes not exceed any of its weightratings — GCWR, GVWR, RGAWR,Trailer Weight Rating, or TongueWeight. The only way to be sure it isnot exceeding any of these ratingsis to weigh the tow vehicle andtrailer combination, fully loaded forthe trip, getting individual weightsfor each of these items.

Towing Equipment

Hitches

The correct hitch equipment helpsmaintain combination control.Most small-to-medium trailers canbe towed with a weight-carryinghitch which simply features acoupler latched to the hitch ball.

Larger trailers may require aweight-distributing hitch thatuses spring bars to distributethe trailer tongue weight amongthe two vehicle and trailer axles.Fifth-wheel and gooseneck hitchesmay also be used. See “Weight ofthe Trailer Tongue” under TrailerTowing on page 9‑95 for ratinglimits with various hitch types.

If a step-bumper hitch will be used,the bumper could be damagedin sharp turns. Make sure thereis ample room when turning toavoid contact between the trailerand the bumper.

Consider using sway controlswith any trailer. Ask a traileringprofessional about sway controlsor refer to the trailer manufacturer'srecommendations and instructions.

Weight‐Distributing HitchAdjustment

A. Body to Ground Distance

B. Front of Vehicle

When using a weight-distributinghitch, the spring bars should beadjusted so the distance (A) is thesame after coupling the trailer to thetow vehicle and adjusting the hitch.



Fifth-Wheel and GooseneckTrailering

Fifth-wheel and gooseneck trailerscan be used with many pickupmodels. These trailers place alarger percentage of the weight(kingpin weight) on the tow vehiclethan conventional trailers. Makesure this weight does not cause thevehicle to exceed GAWR or GVWR.

Fifth-wheel or gooseneck kingpinweight should be 15 to 25 percent ofthe trailer weight up to the maximumamount specified in the traileringchart for the vehicle. See “Weight ofthe Trailer” under Trailer Towing onpage 9‑95 for more information.

The hitch should be located in thepickup bed so that its centerline isover or slightly in front of the rearaxle. Take care that it is not so farforward that it will contact the backof the cab in sharp turns. This isespecially important for short boxpickups. Trailer pin box extensionsand sliding fifth-wheel hitchassemblies can help this condition.There should be at least six inchesof clearance between the top of thepickup box and the bottom of thetrailer shelf that extends overthe box.

Make sure the hitch is attached tothe tow vehicle frame rails. Do notuse the pickup box for support.

Safety Chains

Always attach chains between thevehicle and the trailer. Cross thesafety chains under the tongueof the trailer to help prevent thetongue from contacting the roadif it becomes separated from thehitch. Instructions about safetychains may be provided by thehitch manufacturer or by the trailermanufacturer. If the trailer beingtowed weighs up to 2 271 kg(5,000 lbs) with a factory-installedstep bumper, safety chains maybe attached to the attaching pointson the bumper; otherwise, safetychains should be attached to holeson the trailer hitch platform. Alwaysleave just enough slack so thecombination can turn. Never allowsafety chains to drag on the ground.



Trailer Brakes

A loaded trailer that weighs morethan 900 kg (2,000 lbs) needs tohave its own brake system thatis adequate for the weight of thetrailer. Be sure to read and followthe instructions for the trailer brakesso they are installed, adjusted, andmaintained properly.

If the vehicle is equipped withStabiliTrak, the trailer cannot tapinto the vehicle's hydraulic brakesystem.

The trailer brake system can tapinto the vehicle's hydraulic brakesystem only if:. The trailer parts can withstand

20 650 kPa (3,000 psi) ofpressure.

. The trailer's brake systemwill use less than 0.3 cc(0.02 cubic inch) of fluid fromthe vehicle's master cylinder.Otherwise, both braking systemswill not work well or at all.

If everything checks out this far,make the brake tap at the port onthe master cylinder that sends thefluid to the rear brakes. Use onlysteel brake tubing to make the tap.

Auxiliary Battery

The auxiliary battery provision canbe used to supply electrical powerto additional equipment that may beadded, such as a slide-in camper.If the vehicle has this provision,this relay will be located on thedriver side of the vehicle, next tothe underhood electrical center.

Be sure to follow the properinstallation instructions includedwith any electrical equipment thatis installed.

Notice: Leaving electricalequipment on for extendedperiods will drain the battery.Always turn off electricalequipment when not in useand do not use equipment thatexceeds the maximum amperagerating for the auxiliary batteryprovision.

Trailer Wiring Harness

The vehicle is equipped with one ofthe following wiring harnesses fortowing a trailer or hauling a slide-incamper.

Basic Trailer Wiring

All regular, extended cab and crewcab pickups have a seven‐wiretrailer towing harness.

For vehicles not equipped withheavy duty trailering, the harnessis secured to the vehicle's framebehind the spare tire mount.The harness requires the installationof a trailer connector, which isavailable through your dealer.

If towing a light‐duty trailer witha standard four‐way round pinconnector, an adapter is availablefrom your dealer.



Heavy-DutyTrailer Wiring HarnessPackage

For vehicles equipped with heavyduty trailering, the harness isconnected to a bracket on the hitchplatform. The seven-wire harnesscontains the following trailer circuits:. Yellow: Left Stop/Turn Signal. Dark Green: Right Stop/Turn

Signal

. Brown: Taillamps

. White: Ground

. Light Green: Back-up Lamps

. Red: Battery Feed*

. Dark Blue: Trailer Brake*

*The fuses for these two circuitsare installed in the underhoodelectrical center, but the wires arenot connected. They should beconnected by your dealer or aqualified service center. The fuseand wire for the ITBC is factoryinstalled and connected if thevehicle is equipped with an ITBC.The fuse for the battery feed isnot required if the vehicle has anauxiliary battery. If the vehicle doesnot have an auxiliary battery, haveyour dealer or authorized servicecenter install the required fuse.

If charging a remote (non-vehicle)battery, press the Tow/Haul Modebutton, if equipped, located atthe end of the shift lever. This willboost the vehicle system voltageand properly charge the battery.If the trailer is too light for Tow/Haul Mode, or the vehicle is notequipped with Tow/Haul, turn onthe headlamps as a second wayto boost the vehicle system andcharge the battery.



Camper/Fifth-Wheel Trailer WiringPackage

The seven-wire camper harnessis located under the front edge ofthe pickup box on the driver sideof the vehicle, attached to theframe bracket. A connector mustbe added to the wiring harnesswhich connects to the camper.

The harness contains the followingcamper/trailer circuits:. Yellow: Left Stop/Turn Signal. Dark Green: Right Stop/Turn

Signal. Brown: Taillamps. White: Ground. Light Green: Back-up Lamps. Red: Battery Feed. Dark Blue: Trailer Brake

If the vehicle is equipped with the“Heavy-Duty Trailering” option,please refer to “Heavy-Duty TrailerWiring Package” earlier in thissection.

When the camper-wiring harnessis ordered without the heavy-dutytrailering package, an eight-wireharness with a seven-pin connectoris located at the rear of the vehicleand is tied to the vehicle's frame.

Electric Brake Control WiringProvisions

These wiring provisions areincluded with the vehicle as partof the trailer wiring package. Theseprovisions are for an electric brakecontroller. The instrument panelcontains blunt cut wires behind thesteering column for the trailer brakecontroller. The harness contains thefollowing wires:. Dark Blue: Brake Signal to

Trailer Connector. Red/Black: Battery. Light Blue/White: Brake Switch. White: Ground

The harness should be installed byyour dealer or a qualified servicecenter.



If the vehicle is equipped with anIntegrated Trailer Brake Control(ITBC) System, the blunt cutsexist, but are not connected furtherin the harness. If an aftermarkettrailer brake controller is installed,the ITBC must be disconnected.Do not power both ITBC andaftermarket controllers to controlthe trailer brakes at the same time.

Tow/Haul Mode

Pressing this button at the end ofthe shift lever turns on and off theTow/Haul Mode.

This indicator light on the instrumentpanel cluster comes on when theTow/Haul Mode is on.

Tow/Haul is a feature that assistswhen pulling a heavy trailer or alarge or heavy load. See Tow/HaulMode on page 9‑51 for moreinformation.

Tow/Haul is designed to be mosteffective when the vehicle andtrailer combined weight is at least75 percent of the vehicle's GrossCombined Weight Rating (GCWR).See “Weight of the Trailer” underTrailer Towing on page 9‑95.Tow/Haul is most useful underthe following driving conditions:. When pulling a heavy trailer or

a large or heavy load throughrolling terrain.

. When pulling a heavy traileror a large or heavy load instop-and-go traffic.

. When pulling a heavy traileror a large or heavy load in busyparking lots where improved lowspeed control of the vehicle isdesired.

Operating the vehicle in Tow/Haulwhen lightly loaded or with notrailer at all will not cause damage.However, there is no benefit tothe selection of Tow/Haul whenthe vehicle is unloaded. Such aselection when unloaded mayresult in unpleasant engine andtransmission driving characteristicsand reduced fuel economy. Tow/Haul is recommended only whenpulling a heavy trailer or a largeor heavy load.



Integrated Trailer BrakeControl System

The vehicle may have an IntegratedTrailer Brake Control (ITBC) systemfor electric trailer brakes.

This symbol is located on theTrailer Brake Control Panel onvehicles with an Integrated TrailerBrake Control system. The poweroutput to the trailer brakes is basedon the amount of brake pressurebeing applied by the vehicle’s brakesystem. This available power outputto the trailer brakes can be adjustedto a wide range of traileringsituations.

The ITBC system is integratedwith the vehicle’s brake, antilockbrake, and StabiliTrak (if equipped)systems. In trailering conditions that

cause the vehicle’s antilock brakeor StabiliTrak systems to activate,power sent to the trailer's brakeswill be automatically adjusted tominimize trailer wheel lock-up.This does not imply that the trailerhas StabiliTrak.

2500 and 3500 series vehicleswith StabiliTrak have a Trailer SwayControl (TSC) feature. See TrailerSway Control (TSC) on page 9‑124.

2500 and 3500 series vehicleswith StabiliTrak have a Hill StartAssist (HSA) feature. See Hill StartAssist (HSA) on page 9‑70.

If the vehicle’s brake, antilockbrake, or StabiliTrak systems arenot functioning properly, the ITBCsystem may not be fully functionalor may not function at all. Makesure all of these systems arefully operational to ensure fullfunctionality of the ITBC system.

The ITBC system is poweredthrough the vehicle's electricalsystem. Turning the ignition offwill also turn off the ITBC system.

The ITBC system is fully functionalonly when the ignition is in ON orin RUN.

The ITBC system can only be usedwith trailers with electric brakes.

{ WARNING

Connecting a trailer that is notcompatible with the ITBC systemmay result in reduced or completeloss of trailer braking. Theremay be an increase in stoppingdistance or trailer instability whichcould result in personal injury ordamage to the vehicle, trailer,or other property. An aftermarketcontroller may be available foruse with trailers with surge, air,or electric‐over‐hydraulic trailerbrake systems. To determine thetype of brakes on the trailer andthe availability of controllers,check with your trailermanufacturer or dealer.



When trailering, make sure of thefollowing:. The ITBC system is used only

with trailers that are equippedwith electric brakes.

. All applicable local and federallaws and regulations arefollowed.

. All electrical and mechanicalconnections to the trailer aremade correctly.

. The trailer’s brakes are in properworking condition.

. The trailer and vehicle areproperly loaded for the towingcondition.

The ITBC system is afactory-installed item. Out‐of‐factoryinstallation of this system should notbe attempted. GM is not responsiblefor warranty or performance of thesystem resulting from out‐of‐factoryinstallation.

All DIC warning and servicemessages must first beacknowledged by the driverby pressing the odometer trip stemor the DIC Vehicle Informationbutton (if equipped) before theTrailer Brake Display Page canbe displayed and Trailer Gaincan be adjusted.

TRAILER GAIN: This setting isdisplayed any time the Trailer BrakeDisplay Page is active. This settingcan be adjusted from 0.0 to 10.0with either a trailer connected ordisconnected. To adjust the TrailerGain, press one of the Trailer Gainadjustment buttons located on theTrailer Brake Control Panel. Pressand hold a gain button to cause theTrailer Gain to continuously adjust.To turn the output to the trailer off,adjust the Trailer Gain setting to0.0 (zero).

0.0 (zero) gain is the factory defaultsetting. To properly adjust trailergain, see “Trailer Gain AdjustmentProcedure” later in this section.

TRAILER OUTPUT: This isdisplayed any time a trailer withelectric brakes is connected.Output to the electric brakes isbased on the amount of vehiclebraking present and relative tothe Trailer Gain setting. Outputis displayed from 0 to 10 bars foreach gain setting.

On vehicles with Trailer SwayControl (TSC) or Hill Start Assist(HSA), output to the electric trailerbrakes may be displayed when thesystems are active. See TrailerSway Control (TSC) on page 9‑124and Hill Start Assist (HSA) onpage 9‑70.



The Trailer Output will indicate“- - - - - -” on the Trailer BrakeDisplay Page whenever thefollowing occur:. No trailer is connected. A trailer without electric brakes

is connected (no DIC messageis displayed)

. A trailer with electric brakeshas become disconnected(a CHECK TRAILER WIRINGmessage will also be displayedon the DIC)

. There is a fault present in thewiring to the electric trailerbrakes (a CHECK TRAILERWIRING message will also bedisplayed on the DIC)

. There is a fault in the ITBCsystem (a SERVICE TRAILERBRAKE SYSTEM message willalso be displayed in the DIC)

Manual Trailer Brake Apply

The Manual Trailer Brake ApplyLever is located on the TrailerBrake Control Panel and is usedto apply the trailer’s electric brakesindependent of the vehicle’s brakes.This lever is used in the Trailer GainAdjustment Procedure to properlyadjust the power output to the trailerbrakes. Sliding the lever to the leftwill apply only the trailer brakes.The power output to the trailer isindicated in the Trailer BrakeDisplay Page on the DIC. If thevehicle’s service brakes are appliedwhile using the Manual Trailer BrakeApply Lever, the trailer output powerwill be the greater of the two.

The trailer's and the vehicle's brakelamps will come on when eithervehicle braking or manual trailerbrakes are applied.

Trailer Gain Adjustment Procedure

Trailer Gain should be set for aspecific trailering condition andmust be adjusted any time vehicleloading, trailer loading, or roadsurface conditions change.

Setting the Trailer Gain properlyis needed for the best trailerstopping performance. A trailerthat is over-gained may result inlocked trailer brakes. A trailer thatis under-gained may result in notenough trailer braking. Both ofthese conditions may result inpoorer stopping and stability ofthe vehicle and trailer.



Use the following procedure tocorrectly adjust Trailer Gain foreach towing condition:

1. Make sure the trailer brakes arein proper working condition.

2. Connect a properly loadedtrailer to the vehicle and makeall necessary mechanicaland electrical connections.See Vehicle Load Limits onpage 9‑25 for more information.

3. After the electrical connection ismade to a trailer equipped withelectric brakes:. A TRAILER CONNECTED

message will be brieflydisplayed on the DIC.

. The Trailer Brake DisplayPage will appear on theDIC showing TRAILERGAIN and TRAILEROUTPUT.

. In the Trailer Output displayon the DIC, “- - - - - -” willdisappear if there is noerror present. Connectinga trailer without electricbrakes will not clear thesix dashed lines.

4. Adjust the Trailer Gain by usingthe gain adjustment (+ / -)buttons on the Trailer BrakeControl Panel.

5. Drive the vehicle with thetrailer attached on a level roadsurface representative of thetowing condition and free oftraffic at about 32 to 40 km/h(20 to 25 mph) and fully applythe Manual Trailer Brake ApplyLever.

Adjusting trailer gain at speedslower than 32 to 40 km/h(20 to 25 mph) may resultin an incorrect gain setting.

6. Adjust the Trailer Gain to justbelow the point of trailer wheellock-up, indicated by trailerwheel squeal or tire smokewhen a trailer wheel locks.

Trailer wheel lock-up may notoccur if towing a heavily loadedtrailer. In this case, adjust theTrailer Gain to the highestallowable setting for the towingcondition.

7. Re-adjust Trailer Gain any timevehicle loading, trailer loading orroad surface conditions changeor if trailer wheel lock-up isnoticed at any time while towing.



Other ITBC-Related DIC Messages

In addition to displaying TRAILERGAIN and TRAILER OUTPUTthrough the DIC, trailer connectionand ITBC system status aredisplayed on the DIC.

TRAILER CONNECTED: Thismessage will be briefly displayedwhen a trailer with electric brakesis first connected to the vehicle.This message will automatically turnoff in about 10 seconds. The drivercan also acknowledge this messagebefore it automatically turns off.

1. Disconnect the trailer wiringharness from the vehicle.

2. Turn the ignition off.

3. Wait 10 seconds, then turn theignition back to RUN.

4. If the CHECK TRAILER WIRINGmessage re-appears, theelectrical fault is on thevehicle side.

If the CHECK TRAILER WIRINGmessage only re-appears whenconnecting the trailer wiringharness to the vehicle, theelectrical fault is on thetrailer side.



SERVICE TRAILER BRAKESYSTEM: This message will bedisplayed when there is a problemwith the ITBC system. If thismessage persists over multipleignition cycles, there is a problemwith the ITBC system. Take thevehicle to an authorized GM dealerto have the ITBC system diagnosedand repaired.

If either the CHECK TRAILERWIRING or SERVICE TRAILERBRAKE SYSTEM message isdisplayed while driving the vehicle,power is no longer availableto the trailer brakes. When trafficconditions allow, carefully pull thevehicle over to the side of the roadand turn the ignition off. Check thewiring connection to the trailer andturn the ignition back on. If either ofthese messages continues, eitherthe vehicle or trailer needs service.

An authorized GM dealer maybe able to diagnose and repairproblems with the trailer. However,any diagnosis and repair of thetrailer is not covered under thevehicle warranty. Please contactyour trailer dealer for assistancewith trailer repairs and trailerwarranty information.

Trailer SwayControl (TSC)

Trailer Sway Control (TSC)

2500 and 3500 series vehicles withStabiliTrak have a Trailer SwayControl (TSC) feature. If the vehicleis towing a trailer and the systemdetects that the trailer is swaying,the vehicle's brakes are applied

without the driver pressing the brakepedal. If the vehicle is equipped withthe Integrated Trailer Brake Control(ITBC) system, StabiliTrak may alsoapply the trailer brakes. The TCS/StabiliTrak warning light will flash onthe instrument panel cluster to notifythe driver to reduce speed. If thetrailer continues to sway, StabiliTrakwill reduce engine torque to helpslow the vehicle.

Conversions andAdd-Ons

Add-On ElectricalEquipmentNotice: Do not add anythingelectrical to the vehicle unlessyou check with your dealer first.Some electrical equipment candamage the vehicle and thedamage would not be coveredby the vehicle's warranty. Someadd-on electrical equipment cankeep other components fromworking as they should.

Add-on equipment can drain thevehicle battery, even if the vehicleis not operating.

The vehicle has an airbag system.Before attempting to add anythingelectrical to the vehicle, seeServicing the Airbag-EquippedVehicle on page 3‑46 and AddingEquipment to the Airbag-EquippedVehicle on page 3‑46.

Adding a Snow Plow orSimilar EquipmentBefore installing a snow plow on thevehicle, here are some things youneed to know:

Notice: If your vehicle doesnot have the snow plow preppackage, adding a plow candamage your vehicle, and therepairs would not be covered bywarranty. Unless your vehicle wasbuilt to carry a snow plow, do notadd one to your vehicle. If yourvehicle has the snow plow preppackage, called RPO VYU, thenthe payload your vehicle cancarry will be reduced when asnow plow is installed. Yourvehicle can be damaged if eitherthe front or rear axle ratings orthe Gross Vehicle Weight (GVW)are exceeded.

Some vehicles are built with aspecial snow plow prep package,called RPO VYU. If your vehiclehas this option, you can add aplow to it, provided certain weights,such as the weights on the vehicle'saxles and the Gross VehicleWeight (GVW), are not exceeded.

The plow the vehicle can carrydepends on many things, such as:. The options the vehicle came

with, and the weight of thoseoptions.

. The weight and number ofpassengers you intend to carry.

. The weight of items added tothe vehicle, like a tool box ortruck cap.

. The total weight of anyadditional cargo you intendto carry.



Say, for example, you have a 318 kg(700 lb) snow plow. The total weightof all occupants and cargo insidethe cab should not exceed 135 kg(300 lb). This means that you mayonly be able to carry one passenger.But, even this may be too muchif you have got other equipmentalready adding to the weight ofthe vehicle.

Here are some guidelines for safelycarrying a snow plow on the vehicle:. Make sure the weight on the

front and rear axles does notexceed the axle rating for each.

. For the front axle, if more cargoor passengers must be carried,appropriate counter ballast mustbe installed rear of the rear axle.Counter ballast must be properlysecured so it will not moveduring driving.

. Follow the snowplow manufacturer'srecommendations regardingrear ballast. Rear ballast maybe required to ensure a properfront and rear weight distributionratio, even though the actualweight at the front axle may beless than the front axle rating.

. The snow plow manufactureror installer can assist you indetermining the amount of rearballast required, to help makesure the snowplow/vehiclecombination does not exceedthe GVW rating, the front andrear axle ratings, and the frontand rear weight distribution ratio.

. The total vehicle must notexceed the GVW rating.

Front axle reserve capacity is thedifference between the Gross AxleWeight Rating (GAWR) and the frontaxle weight of the vehicle with full

fuel and passengers. Basically,it is the amount of weight that canbe added to the front axle beforereaching the front GAWR.

The front axle reserve capacityfor the vehicle can be foundin the lower right corner of theCertification/Tire label, as shown.

United States



Canada

In order to calculate the amount ofweight any front accessory, such asa snow plow, is adding to the frontaxle, use the following formula:

(W x (A +W.B.)) /W.B.= Weightthe accessory is adding to thefront axle.

Where:W = Weight of added accessoryA = Distance that the accessoryis in front of the front axleW.B. = Vehicle Wheelbase

For example, adding a 318 kg(700 lb) snow plow actually addsmore than 318 kg (700 lbs) to thefront axle. Using the formula, if thesnow plow is 122 cm (4 ft) in front ofthe front axle and the wheel base is305 cm (10 ft), then:

W = 318 kg (700 lb)A = 122 cm (4 ft)W.B. = 305 cm (10 ft)

(W x (A +W.B.))/W.B. =(700 x (4 + 10))/10 = 445 kg (980 lbs)

So, if the front axle reserve capacityis more than 445 kg (980 lbs), youcould add the snow plow withoutexceeding the front GAWR.

You can add heavier equipmenton the front of the vehicle if youcompensate for it by carrying fewerpassengers, less cargo, or bypositioning cargo toward the rear.



This has the effect of reducing theload on the front. However, the frontGAWR, rear GAWR, and the GrossVehicle Weight Rating (GVWR) mustnever be exceeded.

{ WARNING

On some vehicles that havecertain front mounted equipment,such as a snow plow, it may bepossible to load the front axle tothe front gross axle weight rating(GAWR) but not have enoughweight on the rear axle to haveproper braking performance.If your brakes can not workproperly, you could have a crash.To help your brakes work properlywhen a snow plow is installed,

(Continued)

WARNING (Continued)

always follow the snow plowmanufacturer or installer'srecommendation for rear ballastto ensure a proper front and rearweight distribution ratio, eventhough the actual front weightmay be less than the frontGAWR, and the total vehicleweight is less than the grossvehicle weight rating (GVWR).Maintaining a proper front andrear weight distribution ratio isnecessary to provide properbraking performance.

Total vehicle reserve capacity is thedifference between the GVWR andthe weight of the truck with full fueland passengers. It is the amount ofweight that can be added to thevehicle before reaching the GVWR.Keep in mind that reserve capacitynumbers are intended as a guidewhen selecting the amount ofequipment or cargo the truck cancarry. If unsure of the vehicle's front,rear, or total weight, go to a weighstation and weigh the vehicle.Your dealer can also help with this.

The total vehicle reserve capacityfor the vehicle can be foundin the lower right corner of theCertification/Tire label as shownpreviously.

See your dealer for additionaladvice and information aboutusing a snow plow on the vehicle.Also, see Vehicle Load Limits onpage 9‑25.



Emergency Roof LampProvisions

Vehicles with the RPO VYU snowplow prep package also have anemergency roof lamp provisionpackage, RPO TRW. Wiring for theemergency roof lamp is providedabove the overhead console. SeeAuxiliary Roof-Mounted Lamp onpage 6‑7 for switch location.

Pickup Conversion toChassis CabWe are aware that some vehicleowners might consider havingthe pickup box removed and acommercial or recreational bodyinstalled. Owners should be awarethat, as manufactured, there aredifferences between a chassis caband a pickup with the box removedwhich could affect vehicle safety.The components necessary to adapta pickup to permit its safe use witha specialized body should beinstalled by the body builder.

To ensure proper engineperformance and long life, carefulattention must be paid to engineoil. Following these simple, butimportant steps will help protectyour investment:. Always use engine oil approved

to the proper specification andof the proper viscosity grade.See “Selecting the Right EngineOil” in this section.

. Check the engine oil levelregularly and maintain theproper oil level. See “CheckingEngine Oil” and “When to AddEngine Oil” in this section.

. Always dispose of engine oilproperly. See “What to Do withUsed Oil” in this section.


10-8 Vehicle Care

Checking Engine Oil

It is a good idea to check theengine oil level at each fuel fill.In order to get an accurate reading,the vehicle must be on level ground.The engine oil dipstick handleis a yellow loop. See EngineCompartment Overview onpage 10‑6 for the locationof the engine oil dipstick.

Obtaining an accurate oil levelreading is essential:

1. If the engine has been runningrecently, turn off the engine andallow several minutes for the oilto drain back into the oil pan.Checking the oil level too soonafter engine shutoff will notprovide an accurate oil levelreading.

2. Pull out the dipstick and cleanit with a paper towel or cloth,then push it back in all the way.Remove it again, keeping the tipdown, and check the level.

When to Add Engine Oil

If the oil is below the cross-hatchedarea at the tip of the dipstick, add1 L (1 qt) of the recommendedoil and then recheck the level.See “Selecting the Right Engine Oil”in this section for an explanation ofwhat kind of oil to use. For engineoil crankcase capacity, seeCapacities and Specifications onpage 12‑2.

Notice: Do not add too muchoil. Oil levels above or belowthe acceptable operating rangeshown on the dipstick are harmfulto the engine. If you find thatyou have an oil level above theoperating range, i.e., the enginehas so much oil that the oil levelgets above the cross-hatchedarea that shows the properoperating range, the enginecould be damaged. You shoulddrain out the excess oil or limitdriving of the vehicle and seek aservice professional to removethe excess amount of oil.

See Engine Compartment Overviewon page 10‑6 for the location of theengine oil fill cap.

Add enough oil to put the levelsomewhere in the proper operatingrange. Push the dipstick all the wayback in when through.


Vehicle Care 10-9

Selecting the Right Engine Oil

Selecting the right engine oildepends on both the proper oilspecification and viscosity grade:

Specification

Use and ask for engine oils withthe dexos™ certification mark.Oils meeting the requirementsof the vehicle should have thedexos certification mark on thecontainer. This certification markindicates that the oil has beenapproved to the dexos specification.

This vehicle was filled at the factorywith dexos‐approved engine oil.

Notice: Use only engine oilthat is approved to the dexosspecification or an equivalentengine oil of the appropriateviscosity grade. Engine oilsapproved to the dexosspecification will show thedexos symbol on the container.

Failure to use the recommendedengine oil or equivalent canresult in engine damage notcovered by the vehicle warranty.If you are unsure whether theoil is approved to the dexosspecification, ask your serviceprovider.

Use of Substitute Engine Oils ifdexos is unavailable: In the eventthat dexos‐approved engine oil isnot available at an oil change orfor maintaining proper oil level,you may use substitute engine oildisplaying the API Starburst symboland of SAE 5W-30 viscosity grade.


10-10 Vehicle Care

Use of oils that do not meet thedexos specification, however, mayresult in reduced performance undercertain circumstances.

Viscosity Grade

SAE 5W-30 is the best viscositygrade for the vehicle. Do notuse other viscosity oils such asSAE 10W‐30, 10W‐40, or 20W-50.

Cold Temperature Operation: In anarea of extreme cold, where thetemperature falls below −29°C(−20°F), an SAE 0W-30 oilshould be used. An oil of thisviscosity grade will provide easiercold starting for the engine atextremely low temperatures.When selecting an oil of theappropriate viscosity grade, besure to always select an oil thatmeets the required specification,dexos. See “Specification” earlierin this section for more information.


Vehicle Care 10-11

Engine Oil Additives/EngineOil Flushes

Do not add anything to the oil.The recommended oils with thedexos specification and displayingthe dexos certification mark are allthat is needed for good performanceand engine protection.

Engine oil system flushes are notrecommended and could causeengine damage not covered bythe vehicle warranty.

What to Do with Used Oil

Used engine oil contains certainelements that can be unhealthy foryour skin and could even causecancer. Do not let used oil stay onyour skin for very long. Clean yourskin and nails with soap and water,or a good hand cleaner. Wash orproperly dispose of clothing or ragscontaining used engine oil. See themanufacturer's warnings about theuse and disposal of oil products.

Used oil can be a threat to theenvironment. If you change yourown oil, be sure to drain all theoil from the filter before disposal.Never dispose of oil by putting itin the trash or pouring it on theground, into sewers, or into streamsor bodies of water. Recycle it bytaking it to a place that collectsused oil.

Engine Oil Life System

When to Change Engine Oil

This vehicle has a computer systemthat indicates when to change theengine oil and filter. This is basedon engine revolutions and enginetemperature, and not on mileage.Based on driving conditions, themileage at which an oil change isindicated can vary considerably.For the oil life system to workproperly, the system must be resetevery time the oil is changed.

On some vehicles, when the systemhas calculated that oil life has beendiminished, a CHANGE ENGINEOIL SOON message comes onto indicate that an oil change isnecessary. See Engine OilMessages on page 5‑45. Changethe oil as soon as possible withinthe next 1 000 km (600miles).


10-12 Vehicle Care

It is possible that, if driving underthe best conditions, the oil lifesystem might indicate that an oilchange is not necessary for upto a year. The engine oil and filtermust be changed at least oncea year and, at this time, thesystem must be reset. For vehicleswithout the CHANGE ENGINE OILSOON message, an oil changeis needed when the OIL LIFEREMAINING percentage is near0%. Your dealer has trained servicepeople who will perform this workand reset the system. It is alsoimportant to check the oil regularlyover the course of an oil draininterval and keep it at the properlevel.

If the system is ever resetaccidentally, the oil must bechanged at 5 000 km (3,000 miles)since the last oil change.Remember to reset the oil lifesystem whenever the oil is changed.

How to Reset the Engine OilLife System

Reset the system whenever theengine oil is changed so that thesystem can calculate the nextengine oil change. Always reset theengine oil life to 100% after everyoil change. It will not reset itself.To reset the system on mostvehicles:

1. Display the OIL LIFEREMAINING on the DIC.If the vehicle does not haveDIC buttons, the vehicle mustbe in P (Park) to access thisdisplay. See Driver InformationCenter (DIC) on page 5‑33.

2. Press and hold the SET/RESETbutton on the DIC, or thetrip odometer reset stemif the vehicle does not haveDIC buttons, for more thanfive seconds. The oil life willchange to 100%.

On all vehicles, the Engine Oil LifeSystem can be reset as follows:


2. Fully press the acceleratorpedal slowly three times withinfive seconds.

3. Display the OIL LIFEREMAINING on the DIC.If the display shows 100%,the system is reset. See DriverInformation Center (DIC) onpage 5‑33.

If the vehicle has a CHANGEENGINE OIL SOON messageand it comes back on whenthe vehicle is started and/or theOIL LIFE REMAINING is near 0%,the engine oil life system has notbeen reset. Repeat the procedure.

AutomaticTransmission Fluid(4-Speed Transmission)

When to Check and ChangeAutomatic Transmission Fluid

A good time to check the automatictransmission fluid level is when theengine oil is changed.

Change the fluid and filter atthe intervals listed in ScheduledMaintenance on page 11‑2 and besure to use the transmission fluidlisted in Recommended Fluids andLubricants on page 11‑8.

How to Check AutomaticTransmission Fluid

Because this operation can be alittle difficult, it may be best to havethis done at the dealer servicedepartment.

If not taken to the dealer, be sure tofollow all the instructions here or afalse reading on the dipstick couldresult.

Notice: Too much or toolittle fluid can damage thetransmission. Too much canmean that some of the fluid couldcome out and fall on hot engineparts or exhaust system parts,starting a fire. Too little fluidcould cause the transmissionto overheat. Be sure to get anaccurate reading if checkingthe transmission fluid.

Wait at least 30 minutes beforechecking the transmission fluidlevel if you have been driving:. When outside temperatures are

above 32°C (90°F).. At high speed for quite a while.. In heavy traffic— especially in

hot weather.. While pulling a trailer.

To get the right reading, the fluidshould be at normal operatingtemperature, which is 82°C to 93°C(180°F to 200°F).

Get the vehicle warmed up bydriving about 24 km (15 miles) whenoutside temperatures are above10°C (50°F). If it is colder than 10°C(50°F), drive the vehicle in 3 (Third)until the engine temperature gaugemoves and then remains steady for10 minutes.


10-14 Vehicle Care

A cold fluid check can be madeafter the vehicle has been sittingfor eight hours or more with theengine off, but this is used onlyas a reference. Let the enginerun at idle for five minutes if outsidetemperatures are 10°C (50°F)or more. If it is colder than 10°C(50°F), the engine may have to idlelonger. Should the fluid level be lowduring this cold check, the fluid mustbe checked when hot before addingfluid. Checking the fluid hot will giveyou a more accurate reading of thefluid level.

Checking the Fluid Level

Prepare the vehicle as follows:

1. Park the vehicle on a levelplace. Keep the engine running.

2. With the parking brake applied,place the shift lever in P (Park).

3. With your foot on the brakepedal, move the shift leverthrough each gear range,pausing for about three secondsin each range. Then, positionthe shift lever in P (Park).

4. Let the engine run at idle forthree minutes or more.

Then, without shutting off theengine, follow these steps:

1. Locate the transmission dipstickhandle with this graphic which islocated at the rear of the enginecompartment, on the passengerside of the vehicle.

See Engine CompartmentOverview on page 10‑6 formore information on location.

2. Flip the handle up, then pull outthe dipstick and wipe it with aclean rag or paper towel.

3. Push it back in all the way, waitthree seconds and then pull itback out again.


Vehicle Care 10-15

4. Check both sides of the dipstick,and read the lower level. Thefluid level must be in the COLDarea, below the cross-hatchedarea, for a cold check or in theHOT or cross-hatched area for ahot check. Be sure to keep thedipstick pointed down to get anaccurate reading.

5. If the fluid level is in theacceptable range, push thedipstick back in all the way;then flip the handle down tolock the dipstick in place.

Consistency of Readings

Always check the fluid level at leasttwice using the procedure describedpreviously. Consistency (repeatablereadings) is important to maintainingproper fluid level. If readings are stillinconsistent, contact the dealer.

How to Add AutomaticTransmission Fluid

Refer to Recommended Fluidsand Lubricants on page 11‑8 todetermine what kind of transmissionfluid to use.

Using a funnel, add fluid downthe transmission dipstick tube onlyafter checking the transmissionfluid while it is hot. A cold checkis used only as a reference. If thefluid level is low, add only enoughof the proper fluid to bring thelevel up to the HOT area for a hotcheck. It does not take much fluid,generally less than 0.5 Liter (1 Pint).Do not overfill.

Notice: Use of the incorrectautomatic transmission fluidmay damage the vehicle, and thedamages may not be covered bythe vehicle warranty. Always usethe automatic transmission fluidlisted in Recommended Fluidsand Lubricants on page 11‑8.. After adding fluid, recheck the

fluid level as described under“How to Check AutomaticTransmission Fluid,” earlierin this section.

. When the correct fluid levelis obtained, push the dipstickback in all the way; then flip thehandle down to lock the dipstickin place.

AutomaticTransmission Fluid(6-Speed Transmission)

When to Check and ChangeAutomatic Transmission Fluid

It is usually not necessary tocheck the transmission fluid level.The only reason for fluid loss is atransmission leak or overheatedtransmission. If a small leak issuspected, then use the followingchecking procedures to check thefluid level. However, if there is alarge leak, then it may be necessaryto have the vehicle towed to adealer service department and haveit repaired before driving the vehiclefurther.

Notice: Use of the incorrectautomatic transmission fluidmay damage the vehicle, and thedamages may not be covered bythe vehicle warranty. Always usethe automatic transmission fluidlisted in Recommended Fluidsand Lubricants on page 11‑8.

Change the fluid and filterat the scheduled maintenanceintervals listed in ScheduledMaintenance on page 11‑2.Be sure to use the transmissionfluid listed in Recommended Fluidsand Lubricants on page 11‑8.

Too little fluidcould cause the transmissionto overheat. Be sure to get anaccurate reading if checkingthe transmission fluid.

Before checking the fluid level,prepare the vehicle as follows:

1. Start the engine and park thevehicle on a level surface.Keep the engine running.

2. Apply the parking brake andplace the shift lever in P (Park).


Vehicle Care 10-17

3. With your foot on the brakepedal, move the shift leverthrough each gear range,pausing for about three secondsin each range. Then, move theshift lever back to P (Park).

4. Allow the engine to idle(500 – 800 rpm) for at least1 minute. Slowly release thebrake pedal.

5. Keep the engine running andpress the Trip/Fuel button ortrip odometer reset stem untilTRANS TEMP (TransmissionTemperature) displays on theDriver Information Center (DIC).

6. Using the TRANS TEMPreading, determine andperform the appropriate checkprocedure. If the TRANS TEMPreading is not within the requiredtemperature ranges, allow thevehicle to cool, or operate thevehicle until the appropriatetransmission fluid temperatureis reached.

Cold Check Procedure

Use this procedure only as areference to determine if thetransmission has enough fluidto be operated safely until a hotcheck procedure can be made.The hot check procedure is themost accurate method to check thefluid level. Perform the hot checkprocedure at the first opportunity.Use this cold check procedureto check fluid level when thetransmission temperature isbetween 27°C and 32°C(80°F and 90°F).

1. Locate the transmissiondipstick at the rear of the enginecompartment, on the passengerside of the vehicle.

See Engine CompartmentOverview on page 10‑6 formore information.


3. Install the dipstick by pushingit back in all the way; waitthree seconds, and then pullit back out again.

4. Check both sides of the dipstickand read the lower level. Repeatthe check procedure to verify thereading.


10-18 Vehicle Care

5. If the fluid level is below theCOLD check band, add onlyenough fluid as necessary tobring the level into the COLDband. It does not take muchfluid, generally less than 0.5 Liter(1 Pint). Do not overfill.

6. Perform a hot check atthe first opportunity after thetransmission reaches a normaloperating temperature between71°C to 93°C (160°F to 200°F).

7. If the fluid level is in theacceptable range, push thedipstick back in all the way,then flip the handle down tolock the dipstick in place.

Hot Check Procedure

Use this procedure to check thetransmission fluid level when thetransmission fluid temperatureis between 71°C and 93°C(160°F and 200°F).

The hot check is the most accuratemethod to check the fluid level.The hot check should be performedat the first opportunity in order toverify the cold check. The fluid levelrises as fluid temperature increases,so it is important to ensure thetransmission temperature is withinrange.

1. Locate the transmissiondipstick at the rear of the enginecompartment, on the passengerside of the vehicle.

See Engine CompartmentOverview on page 10‑6 formore information.


3. Install the dipstick by pushingit back in all the way; waitthree seconds, and then pullit back out again.

4. Check both sides of the dipstickand read the lower level. Repeatthe check procedure to verify thereading.


Vehicle Care 10-19

5. Safe operating level is within theHOT cross hatch band on thedipstick. If the fluid level is notwithin the HOT band, and thetransmission temperature isbetween 71°C and 93°C (160°Fand 200°F), add or drain fluid asnecessary to bring the level intothe HOT band. If the fluid levelis low, add only enough fluidto bring the level into the HOTband. It does not take muchfluid, generally less than 0.5 L(1 pint). Do not overfill.

6. If the fluid level is in theacceptable range, push thedipstick back in all the way,then flip the handle down tolock the dipstick in place.

Consistency of Readings

Always check the fluid level at leasttwice using the procedure describedpreviously. Consistency (repeatablereadings) is important to maintainingproper fluid level. If readings are stillinconsistent, contact the dealer.

Engine Air Cleaner/FilterIf the vehicle has a diesel engine,see “Pickup Models” under “EngineAir Cleaner/Filter” in the Duramax®

WARNING (Continued)

Do not run the engine if there isa leak. If you run the engine, itcould lose all coolant. That couldcause an engine fire, and youcould be burned. Get any leakfixed before you drive the vehicle.

Notice: Using coolant other thanDEX-COOL® can cause prematureengine, heater core, or radiatorcorrosion. In addition, the enginecoolant could require changingsooner, at 50 000 km (30,000mi)or 24months, whichever occursfirst. Any repairs would not becovered by the vehicle warranty.Always use DEX-COOL(silicate-free) coolant in thevehicle.


10-22 Vehicle Care

Engine CoolantThe cooling system in the vehicleis filled with DEX-COOL® enginecoolant. This coolant is designed toremain in the vehicle for 5 years or240 000 km (150,000 mi), whicheveroccurs first.

The following explains the coolingsystem and how to check and addcoolant when it is low. If there is aproblem with engine overheating,see Engine Overheating onpage 10‑25.

What to Use

{ WARNING

Adding only plain water or someother liquid to the cooling systemcan be dangerous. Plain waterand other liquids, can boil beforethe proper coolant mixture will.The coolant warning system isset for the proper coolant mixture.With plain water or the wrongmixture, the engine could get toohot but you would not get theoverheat warning. The enginecould catch fire and you orothers could be burned. Use a50/50 mixture of clean, drinkablewater and DEX-COOL coolant.

Use a 50/50 mixture of clean,drinkable water and DEX-COOLcoolant. If using this mixture,nothing else needs to be added.This mixture:. Gives freezing protection down

to −37°C (−34°F), outsidetemperature

. Gives boiling protectionup to 129°C (265°F), enginetemperature

. Protects against rust andcorrosion

. Will not damage aluminum parts

. Helps keep the proper enginetemperature

Notice: If an improper coolantmixture is used, the engine couldoverheat and be badly damaged.The repair cost would not becovered by the vehicle warranty.Too much water in the mixturecan freeze and crack the engine,radiator, heater core, and otherparts.


Vehicle Care 10-23

Notice: If extra inhibitorsand/or additives are used inthe vehicle cooling system,the vehicle could be damaged.Use only the proper mixture ofthe engine coolant listed in thismanual for the cooling system.See Recommended Fluids andLubricants on page 11‑8 for moreinformation.

Never dispose of engine coolantby putting it in the trash, pouringit on the ground, or into sewers,streams, or bodies of water.Have the coolant changed by anauthorized service center, familiarwith legal requirements regardingused coolant disposal. This will helpprotect the environment and yourhealth.

Checking Coolant

The coolant surge tank is locatedin the engine compartment on thepassenger side of the vehicle.See Engine Compartment Overviewon page 10‑6 for more informationon location.

The vehicle must be on a levelsurface when checking the coolantlevel.

Check to see if coolant is visiblein the coolant surge tank. If thecoolant inside the coolant surgetank is boiling, do not do anythingelse until it cools down. If coolant isvisible but the coolant level is not ator above the FULL COLD mark, adda 50/50 mixture of clean, drinkablewater and DEX-COOL coolant at thecoolant surge tank, but be sure thecooling system is cool before thisis done.

The coolant level should be at orabove the FULL COLD mark. If it isnot, there may be a leak in thecooling system.


10-24 Vehicle Care

How to Add Coolant to theCoolant Surge Tank forGasoline Engines

If the vehicle has a diesel engine,see “Cooling System” in theDuramax Diesel Supplement forthe proper coolant fill procedure.

{ WARNING

You can be burned if you spillcoolant on hot engine parts.Coolant contains ethylene glycoland it will burn if the engine partsare hot enough. Do not spillcoolant on a hot engine.

Notice: This vehicle has aspecific coolant fill procedure.Failure to follow this procedurecould cause the engine tooverheat and be severelydamaged.

{ WARNING

An electric engine cooling fanunder the hood can start up evenwhen the engine is not runningand can cause injury. Keephands, clothing, and tools awayfrom any underhood electric fan.

{ WARNING

Steam and scalding liquids from ahot cooling system can blow outand burn you badly. They areunder pressure, and if you turnthe coolant surge tank pressurecap— even a little— they cancome out at high speed. Neverturn the cap when the coolingsystem, including the coolantsurge tank pressure cap, is hot.Wait for the cooling system andcoolant surge tank pressure capto cool if you ever have to turnthe pressure cap.

If no coolant is visible in the surgetank, add coolant as follows:

1. Remove the coolant surge tankpressure cap when the coolingsystem, including the coolantsurge tank pressure cap andupper radiator hose, is nolonger hot.

Turn the pressure cap slowlycounterclockwise about one fullturn. If a hiss is heard, wait forthat to stop. A hiss means thereis still some pressure left.

2. Keep turning the pressure capslowly, and remove it.


Vehicle Care 10-25

3. Fill the coolant surge tankwith the proper mixture to theFULL COLD mark.

4. With the coolant surge tankpressure cap off, start theengine and let it run until theengine coolant temperaturegauge indicates approximately90°C (195°F).

By this time, the coolant levelinside the coolant surge tankmay be lower. If the level islower, add more of the propermixture to the coolant surgetank until the level reaches theFULL COLD mark.

5. Replace the pressure cap.Be sure the pressure cap ishand-tight and fully seated.

6. Verify coolant level after theengine is shut off and thecoolant is cold. If necessary,repeat coolant fill procedureSteps 1 through 6.

Notice: If the pressure cap isnot tightly installed, coolant lossand possible engine damage mayoccur. Be sure the cap is properlyand tightly secured.

Engine OverheatingIf the vehicle has the Duramax®

Diesel engine, see the DuramaxDiesel Supplement for moreinformation.

The vehicle has several indicatorsto warn of engine overheating.

There is a coolant temperaturegauge on the vehicle's instrumentpanel. See Engine CoolantTemperature Gauge on page 5‑17.

In addition, there are ENGINEOVERHEATED STOP ENGINE,ENGINE OVERHEATED IDLEENGINE, and ENGINE POWER ISREDUCED messages in the DriverInformation Center (DIC) on theinstrument panel. See EngineCooling System Messages onpage 5‑44 and Engine PowerMessages on page 5‑45.


10-26 Vehicle Care

If the decision is made not to lift thehood when this warning appears,get service help right away.See Roadside Assistance Program(U.S. and Canada) on page 13‑8or Roadside Assistance Program(Mexico) on page 13‑10.

If the decision is made to lift thehood, make sure the vehicle isparked on a level surface.

Then check to see if the enginecooling fans are running. If theengine is overheating, both fansshould be running. If they are not,do not continue to run the engineand have the vehicle serviced.

Notice: Engine damage fromrunning your engine withoutcoolant is not covered by thevehicle warranty. See OverheatedEngine Protection OperatingMode for information on drivingto a safe place in an emergency.

Notice: If the engine catches firewhile driving with no coolant, thevehicle can be badly damaged.The costly repairs would notbe covered by the vehiclewarranty. See Overheated EngineProtection Operating Mode onpage 10‑28 for information ondriving to a safe place in anemergency.

If Steam is Coming from theEngine Compartment

{ WARNING

Steam from an overheated enginecan burn you badly, even if youjust open the hood. Stay awayfrom the engine if you see orhear steam coming from it.Turn it off and get everyoneaway from the vehicle until itcools down. Wait until thereis no sign of steam or coolantbefore you open the hood.

If No Steam is Coming fromthe Engine Compartment

The ENGINE OVERHEATEDSTOP ENGINE or the ENGINEOVERHEATED IDLE ENGINEmessage, along with a low coolantcondition, can indicate a seriousproblem.

If there is an engine overheatwarning, but no steam is seen orheard, the problem may not be tooserious. Sometimes the engine canget a little too hot when the vehicle:. Climbs a long hill on a hot day. Stops after high-speed driving. Idles for long periods in traffic. Tows a trailer; see Trailer Towing

on page 9‑95.

If the ENGINE OVERHEATEDSTOP ENGINE or the ENGINEOVERHEATED IDLE ENGINEmessage appears with no sign ofsteam, try this for a minute or so:

1. Turn the air conditioning off.

2. Turn the heater on to the highesttemperature and to the highestfan speed. Open the windowsas necessary.

3. If stopped in a traffic jam, applythe brake, shift to N (Neutral);otherwise, shift to the highestgear while driving—D (Drive)or 3 (Third).

If the temperature overheat gaugeis no longer in the overheat zoneor an overheat warning no longerdisplays, the vehicle can be driven.

Continue to drive the vehicle slowlyfor about 10 minutes. Keep a safevehicle distance from the vehicle infront. If the warning does not comeback on, continue to drive normally.

If the warning continues, pullover, stop, and park the vehicleright away.

If there is no sign of steam, idlethe engine for five minutes whileparked. If the warning is stilldisplayed, turn off the engine until itcools down. Also, see “OverheatedEngine Protection Operating Mode”later in this section.


10-28 Vehicle Care

Overheated EngineProtectionOperating ModeIf an overheated engine conditionexists and the ENGINE POWER ISREDUCED message displays, anoverheat protection mode whichalternates firing groups of cylindershelps to prevent engine damage.In this mode, a loss in power andengine performance will be noticed.This operating mode allows thevehicle to be driven to a safeplace in an emergency. Drivingextended km (mi) and/or towing atrailer in the overheat protectionmode should be avoided.

Notice: After driving in theoverheated engine protectionoperating mode, to avoid enginedamage, allow the engine to coolbefore attempting any repair.The engine oil will be severelydegraded. Repair the causeof coolant loss, change the oiland reset the oil life system.See Engine Oil on page 10‑7.

Engine FanIf the vehicle has a clutched enginecooling fan, when the clutch isengaged, the fan spins faster toprovide more air to cool the engine.In most everyday driving conditions,the fan is spinning slower andthe clutch is not fully engaged.This improves fuel economy andreduces fan noise. Under heavyvehicle loading, trailer towing,and/or high outside temperatures,the fan speed increases as theclutch more fully engages, so anincrease in fan noise may be heard.This is normal and should not bemistaken as the transmissionslipping or making extra shifts.It is merely the cooling systemfunctioning properly. The fan willslow down when additional coolingis not required and the clutchdisengages.

This fan noise may also be heardwhen starting the engine. It will goaway as the fan clutch partiallydisengages.

If the vehicle has electric coolingfans, the fans may be heardspinning at low speed duringmost everyday driving. The fansmay turn off if no cooling is required.Under heavy vehicle loading, trailertowing, high outside temperatures,or operation of the air conditioningsystem, the fans may change tohigh speed and an increase in fannoise may be heard. This is normaland indicates that the coolingsystem is functioning properly.The fans will change to low speedwhen additional cooling is nolonger required.

Power Steering Fluid

See Engine Compartment Overviewon page 10‑6 for reservoir location.

When to Check Power SteeringFluid

It is not necessary to regularlycheck power steering fluid unlessthere is a leak suspected in thesystem or an unusual noise isheard. A fluid loss in this systemcould indicate a problem. Have thesystem inspected and repaired.

How to Check Power SteeringFluid

To check the power steering fluid:

1. Turn the key off and let theengine compartment cool down.

2. Wipe the cap and the top of thereservoir clean.

3. Unscrew the cap and wipe thedipstick with a clean rag.

4. Replace the cap and completelytighten it.

5. Remove the cap again and lookat the fluid level on the dipstick.

The level should be at theFULL COLD mark. If necessary,add only enough fluid to bring thelevel up to the mark.

What to Use

To determine what kind of fluid touse, see Recommended Fluids andLubricants on page 11‑8. Alwaysuse the proper fluid.

Notice: Use of the incorrect fluidmay damage the vehicle and thedamages may not be covered bythe vehicle's warranty. Alwaysuse the correct fluid listed inRecommended Fluids andLubricants on page 11‑8.

Washer Fluid

What to Use

When windshield washer fluid needsto be added, be sure to read themanufacturer's instructions beforeuse. Use a fluid that has sufficientprotection against freezing in anarea where the temperature mayfall below freezing.


10-30 Vehicle Care

Adding Washer Fluid

The vehicle has a low washer fluidmessage on the DIC that comeson when the washer fluid is low.The message is displayed for15 seconds at the start of eachignition cycle. When the WASHERFLUID LOW ADD FLUID messagedisplays, washer fluid will need tobe added to the windshield washerfluid reservoir.

Open the cap with the washersymbol on it. Add washer fluiduntil the tank is full. See EngineCompartment Overview onpage 10‑6 for reservoir location.

Notice:. When using concentratedwasher fluid, follow themanufacturer's instructionsfor adding water.

. Do not mix water withready-to-use washer fluid.Water can cause the solutionto freeze and damage thewasher fluid tank and otherparts of the washer system.Also, water does not cleanas well as washer fluid.

. Fill the washer fluid tankonly three-quarters fullwhen it is very cold. Thisallows for fluid expansionif freezing occurs, whichcould damage the tank ifit is completely full.

. Do not use engine coolant(antifreeze) in the windshieldwasher. It can damage thewindshield washer systemand paint.

BrakesThis vehicle has front disc brakesand could have rear drum brakes orrear disc brakes.

Disc brake pads have built-in wearindicators that make a high-pitchedwarning sound when the brake padsare worn and new pads are needed.The sound can come and go orbe heard all the time the vehicle ismoving, except when applying thebrake pedal firmly.

{ WARNING

The brake wear warning soundmeans that soon the brakes willnot work well. That could lead toa crash. When the brake wearwarning sound is heard, have thevehicle serviced.

Notice: Continuing to drive withworn-out brake pads could resultin costly brake repair.


Vehicle Care 10-31

Some driving conditions or climatescan cause a brake squeal whenthe brakes are first applied orlightly applied. This does not meansomething is wrong with the brakes.

Properly torqued wheel nuts arenecessary to help prevent brakepulsation. When tires are rotated,inspect brake pads for wear andevenly tighten wheel nuts inthe proper sequence to torquespecifications in Capacities andSpecifications on page 12‑2.

If the vehicle has rear drum brakes,they do not have wear indicators,but if a rear brake rubbing noise isheard, have the rear brake liningsinspected immediately. Rear brakedrums should be removed andinspected each time the tires areremoved for rotation or changing.

Drum brakes have an inspectionhole to inspect lining wear duringscheduled maintenance. Whenthe front brake pads are replaced,have the rear brakes inspected, too.

Brake linings should always bereplaced as complete axle sets.

Brake Pedal Travel

See your dealer if the brake pedaldoes not return to normal height,or if there is a rapid increase inpedal travel. This could be asign that brake service mightbe required.

Brake Adjustment

Every time the brakes are applied,with or without the vehicle moving,the brakes adjust for wear.

Replacing Brake System Parts

The braking system on a vehicle iscomplex. Its many parts have to beof top quality and work well togetherif the vehicle is to have really goodbraking. The vehicle was designedand tested with top-quality brakeparts. When parts of the brakingsystem are replaced, be sure to getnew, approved replacement parts.If this is not done, the brakes mightnot work properly. For example,installing disc brake pads thatare wrong for the vehicle, canchange the balance between thefront and rear brakes — for theworse. The braking performanceexpected can change in manyother ways if the wrong replacementbrake parts are installed.


10-32 Vehicle Care

Brake Fluid

The brake master cylinder reservoiris filled with DOT 3 brake fluid.See Engine Compartment Overviewon page 10‑6 for the location of thereservoir.

There are only two reasons whythe brake fluid level in the reservoirmight go down:. The brake fluid level goes down

because of normal brake liningwear. When new linings areinstalled, the fluid level goesback up.

. A fluid leak in the brakehydraulic system can alsocause a low fluid level. Havethe brake hydraulic system fixed,since a leak means that sooneror later the brakes will notwork well.

Do not top off the brake fluid.Adding fluid does not correct aleak. If fluid is added when thelinings are worn, there will be toomuch fluid when new brake liningsare installed. Add or remove brakefluid, as necessary, only when workis done on the brake hydraulicsystem.

{ WARNING

If too much brake fluid is added,it can spill on the engine andburn, if the engine is hot enough.You or others could be burned,

Check brake fluid by looking at thebrake fluid reservoir. See EngineCompartment Overview onpage 10‑6.

The fluid level should be aboveMIN. If it is not, have the brakehydraulic system checked to seeif there is a leak.

After work is done on the brakehydraulic system, make sure thelevel is above the MIN but notover the MAX mark.

What to Add

Use only new DOT 3 brakefluid from a sealed container.See Recommended Fluids andLubricants on page 11‑8.

Always clean the brake fluidreservoir cap and the area aroundthe cap before removing it.This helps keep dirt fromentering the reservoir.

{ WARNING

With the wrong kind of fluid inthe brake hydraulic system,the brakes might not work well.This could cause a crash. Alwaysuse the proper brake fluid.

Notice:. Using the wrong fluidcan badly damage brakehydraulic system parts.For example, just a fewdrops of mineral-based oil,such as engine oil, in thebrake hydraulic system candamage brake hydraulicsystem parts so badly thatthey will have to be replaced.Do not let someone put inthe wrong kind of fluid.

. If brake fluid is spilled on thevehicle's painted surfaces,the paint finish can bedamaged. Be careful notto spill brake fluid on thevehicle. If you do, wash itoff immediately.

What to Use


Rear Axle

When to Check Lubricant

It is not necessary to regularlycheck rear axle fluid unless a leakis suspected or an unusual noiseis heard. A fluid loss could indicatea problem. Have it inspected andrepaired.

All axle assemblies are filled byvolume of fluid during production.They are not filled to reach acertain level. When checking thefluid level on any axle, variationsin the readings can be caused byfactory fill differences between theminimum and the maximum fluidvolume. Also, if a vehicle has justbeen driven before checking thefluid level, it may appear lower than

normal because fluid has traveledout along the axle tubes and hasnot drained back to the sumparea. Therefore, a reading takenfive minutes after the vehicle hasbeen driven will appear to have alower fluid level than a vehicle thathas been stationary for an hour ortwo. Remember that the rear axleassembly must be supported toget a true reading.

Headlamp AimingThe vehicle has a visual opticalheadlamp aiming system. The aimof the headlamps has been presetat the factory and should need nofurther adjustment.

However, if the vehicle is damagedin a crash, the aim of the headlampsmay be affected and adjustmentmay be necessary.

If oncoming vehicles flash their highbeams at you, this may mean thevertical aim of the headlamps needsto be adjusted.

It is recommended that the vehiclebe taken to the dealer for service ifthe headlamps need to be adjusted.It is possible, however, to re-aim theheadlamps as described.

The vehicle should:. Be placed so the headlamps

are 7.6 m (25 ft) from alight‐colored wall.

. Have all four tires on a levelsurface which is level all theway to the wall.

. Be placed so it is perpendicularto the wall.

. Not have any snow, ice, or mudon it.

. Be fully assembled and all otherwork stopped while headlampaiming is being performed.

. Be loaded with a full tank offuel and one person or 75 kg(160 lbs) sitting on thedriver seat.

. Have the tires properly inflated.

. Have the spare tire in its properlocation in the vehicle.

Headlamp aiming is done with thevehicle's low-beam headlamps.The high-beam headlamps will becorrectly aimed if the low-beamheadlamps are aimed properly.

To adjust the vertical aim:

1. Open the hood. See Hood onpage 10‑5.

2. Locate the aim dot on the lens ofthe low‐beam headlamp.

3. Record the distance from theground to the aim dot on thelow‐beam headlamp.


Vehicle Care 10-43

4. At a wall, measure from theground upward (A) to therecorded distance fromStep 3 and mark it.

5. Draw or tape a horizontal line (B)on the wall the width of thevehicle at the height of themark in Step 4.

Notice: Do not cover a headlampto improve beam cut-off whenaiming. Covering a headlamp maycause excessive heat build-upwhich may cause damage to theheadlamp.

6. Turn on the low-beamheadlamps and place apiece of cardboard or equivalentin front of the headlamp notbeing adjusted. This allowsonly the beam of light from theheadlamp being adjusted to beseen on the flat surface.

7. Locate the vertical headlampaiming screws, which are underthe hood near each headlampassembly.

The adjustment screw can beturned with an E8 Torx® socket.

8. Turn the vertical aiming screwuntil the headlamp beamis aimed to the horizontaltape line. Turn it clockwise orcounterclockwise to raise orlower the angle of the beam.

Electrical System

Electrical SystemOverloadThe vehicle has fuses and circuitbreakers to protect against anelectrical system overload.

When the current electrical load istoo heavy, the circuit breaker opensand closes, protecting the circuituntil the current load returns tonormal or the problem is fixed.This greatly reduces the chanceof circuit overload and fire causedby electrical problems.

Fuses and circuit breakers protectthe following in the vehicle:. Headlamp Wiring. Windshield Wiper Motor. Power Windows and Other

Power Accessories

Replace a bad fuse with a new oneof the identical size and rating.

If there is a problem on the roadand a fuse needs to be replaced,the same amperage fuse can beborrowed. Choose some feature ofthe vehicle that is not needed to useand replace it as soon as possible.

Headlamp Wiring

An electrical overload may causethe lamps to go on and off, or insome cases to remain off. Havethe headlamp wiring checked rightaway if the lamps go on and off orremain off.

Windshield Wipers

If the wiper motor overheats due toheavy snow or ice, the windshieldwipers will stop until the motor coolsand will then restart.

Although the circuit is protectedfrom electrical overload, overloaddue to heavy snow or ice maycause wiper linkage damage.Always clear ice and heavy snowfrom the windshield before usingthe windshield wipers.

If the overload is caused by anelectrical problem and not snow orice, be sure to get it fixed.


10-50 Vehicle Care

Fuses and CircuitBreakersIf the vehicle is a hybrid, seethe hybrid supplement for moreinformation.

The wiring circuits in the vehicleare protected from short circuitsby a combination of fuses, circuitbreakers and fusible thermal links.This greatly reduces the chance offires caused by electrical problems.

Look at the silver-colored bandinside the fuse. If the band is brokenor melted, replace the fuse. Be sureyou replace a bad fuse with a newone of the identical size and rating.

If you ever have a problem on theroad and don't have a spare fuse,you can borrow one that has thesame amperage. Just pick some

feature of your vehicle that you canget along without – like the radioor cigarette lighter – and use itsfuse, if it is the correct amperage.Replace it as soon as you can.

Engine CompartmentFuse BlockIf the vehicle has a diesel engine,see the Duramax Diesel supplementfor more information.


The Engine Compartment FuseBlock is located in the enginecompartment, on the driver sideof the vehicle.

Lift the cover to access the fuseblock.

Notice: Spilling liquid on anyelectrical component on thevehicle may damage it. Alwayskeep the covers on any electricalcomponent.

To remove fuses, hold the end ofthe fuse between your thumb andindex finger and pull straight out.

Tire PressureTires need the correct amountof air pressure to operateeffectively.

Notice: Neither tireunderinflation noroverinflation is good.Underinflated tires, ortires that do not haveenough air, can result in:. Tire overloading andover-heating whichcould lead to a blowout.

. Premature orirregular wear.

. Poor handling.

. Reduced fuel economy.

Overinflated tires, or tiresthat have too much air, canresult in:. Unusual wear.. Poor handling.. Rough ride.. Needless damage fromroad hazards.

A vehicle-specific Tire andLoading Information labelis attached to the vehicle.This label shows the vehicle'soriginal equipment tires and thecorrect inflation pressures forthe tires when they are cold.The recommended cold tireinflation pressure, shown onthe label, is the minimumamount of air pressure neededto support the vehicle'smaximum load-carrying capacity.

For additional informationregarding how much weightthe vehicle can carry, and anexample of the Tire and LoadingInformation label, see VehicleLoad Limits on page 9‑25.How you load the vehicleaffects vehicle handling andride comfort. Never load thevehicle with more weight thanit was designed to carry.

When to Check

Check the tires once a monthor more.

Do not forget to check thepressure of the spare tire, if thevehicle has one. See Full-SizeSpare Tire on page 10‑97 foradditional information.


Vehicle Care 10-67

How to Check

Use a good quality pocket-typegauge to check tire pressure.You cannot tell if the tires areproperly inflated simply bylooking at them. Radial tires maylook properly inflated even whenthey are under-inflated. Checkthe tire's inflation pressure whenthe tires are cold. Cold meansthe vehicle has been sitting forat least three hours or driven nomore than 1.6 km (1 mile).

Remove the valve cap from thetire valve stem. Press the tiregauge firmly onto the valve toget a pressure measurement.If the cold tire inflation pressurematches the recommendedpressure on the Tire andLoading Information label,no further adjustment isnecessary. If the pressureis low, add air until you reachthe recommended amount.

If you overfill the tire, release airby pushing on the metal stemin the center of the tire valve.Recheck the tire pressure withthe tire gauge.

Be sure to put the valve capsback on the valve stems.They help prevent leaks bykeeping out dirt and moisture.

Tire Pressure forHigh-Speed Operation

{ WARNING

Driving at high speeds,160 km/h (100mph) or higher,puts an additional strain on tires.Sustained high-speed drivingcauses excessive heat build upand can cause sudden tire failure.You could have a crash and youor others could be killed. Somehigh-speed rated tires require

(Continued)

WARNING (Continued)

inflation pressure adjustmentfor high speed operation. Whenspeed limits and road conditionsare such that a vehicle can bedriven at high speeds, make surethe tires are rated for high speedoperation, in excellent condition,and set to the correct cold tireinflation pressure for thevehicle load.

Vehicles with P265/70R17 orP275/55R20 size tires requireinflation pressure adjustmentwhen driving the vehicle at speedsof 160 km/h (100mph) or higher.Set the cold tire inflation pressureto 20 kPa (3 psi) above therecommended cold tire pressureshown on the Tire and LoadingInformation label.


10-68 Vehicle Care

When you end this high‐speeddriving, return the tires to the coldinflation pressure shown on theTire and Loading Informationlabel. See Vehicle Load Limits onpage 9‑25 and Tire Pressure onpage 10‑66.

Tire Pressure MonitorSystemThe Tire Pressure Monitor System(TPMS) uses radio and sensortechnology to check tire pressurelevels. The TPMS sensors monitorthe air pressure in your tires andtransmit tire pressure readings toa receiver located in the vehicle.

Each tire, including the spare(if provided), should be checkedmonthly when cold and inflated tothe inflation pressure recommendedby the vehicle manufacturer on thevehicle placard or tire inflation

pressure label. (If your vehicle hastires of a different size than the sizeindicated on the vehicle placard ortire inflation pressure label, youshould determine the proper tireinflation pressure for those tires.)

As an added safety feature, yourvehicle has been equipped with atire pressure monitoring system(TPMS) that illuminates a lowtire pressure telltale when one ormore of your tires is significantlyunder‐inflated.

Accordingly, when the low tirepressure telltale illuminates, youshould stop and check your tires assoon as possible, and inflate themto the proper pressure. Driving ona significantly under‐inflated tirecauses the tire to overheat and canlead to tire failure. Under‐inflationalso reduces fuel efficiency andtire tread life, and may affect thevehicle's handling and stoppingability.

Please note that the TPMS isnot a substitute for proper tiremaintenance, and it is the driver'sresponsibility to maintain correct tirepressure, even if under‐inflationhas not reached the level to triggerillumination of the TPMS low tirepressure telltale.

Your vehicle has also beenequipped with a TPMS malfunctionindicator to indicate when thesystem is not operating properly.The TPMS malfunction indicator iscombined with the low tire pressuretelltale. When the system detects amalfunction, the telltale will flash forapproximately one minute and thenremain continuously illuminated.This sequence will continue uponsubsequent vehicle start‐ups aslong as the malfunction exists.


Vehicle Care 10-69

When the malfunction indicatoris illuminated, the system maynot be able to detect or signal lowtire pressure as intended. TPMSmalfunctions may occur for a varietyof reasons, including the installationof replacement or alternate tires orwheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or moretires or wheels on your vehicle toensure that the replacement oralternate tires and wheels allowthe TPMS to continue to functionproperly.

See Tire Pressure MonitorOperation on page 10‑69 foradditional information.

Federal CommunicationsCommission (FCC) andIndustry Canada

See Radio Frequency Statement onpage 13‑19 for informationregarding Part 15 of the FederalCommunications Commission(FCC) rules and Industry CanadaStandards RSS-210/220/310.

Tire Pressure MonitorOperationThis vehicle may have a TirePressure Monitor System (TPMS).The TPMS is designed to warn thedriver when a low tire pressurecondition exists. TPMS sensors aremounted onto each tire and wheelassembly, excluding the spare tireand wheel assembly. The TPMSsensors monitor the air pressurein the tires and transmit the tirepressure readings to a receiverlocated in the vehicle.

When a low tire pressure conditionis detected, the TPMS illuminatesthe low tire pressure warning lightlocated on the instrument cluster.If the warning light comes on, stopas soon as possible and inflate thetires to the recommended pressureshown on the Tire and LoadingInformation label. See VehicleLoad Limits on page 9‑25.

A message to check the pressurein a specific tire displays in theDriver Information Center (DIC).The low tire pressure warninglight and the DIC warning messagecome on at each ignition cycleuntil the tires are inflated to thecorrect inflation pressure. If thevehicle has DIC buttons, tirepressure levels can be viewed.


10-70 Vehicle Care

For additional information anddetails about the DIC operation anddisplays, see Driver InformationCenter (DIC) on page 5‑33 andTire Messages on page 5‑49.

The low tire pressure warning lightmay come on in cool weather whenthe vehicle is first started, and thenturn off as the vehicle is driven.This could be an early indicator thatthe air pressure is getting low andneeds to be inflated to the properpressure.

A Tire and Loading Informationlabel shows the size of the originalequipment tires and the correctinflation pressure for the tires whenthey are cold. See Vehicle LoadLimits on page 9‑25, for an exampleof the Tire and Loading Informationlabel and its location. Also seeTire Pressure on page 10‑66.

The TPMS can warn about alow tire pressure condition butit does not replace normal tiremaintenance. See Tire Inspectionon page 10‑73, Tire Rotation onpage 10‑73 and Tires onpage 10‑57.

Notice: Tire sealant materials arenot all the same. A non-approvedtire sealant could damage theTPMS sensors. TPMS sensordamage caused by usingan incorrect tire sealant isnot covered by the vehiclewarranty. Always use onlythe GM-approved tire sealantavailable through your dealeror included in the vehicle.

TPMS Malfunction Light andMessage

The TPMS will not function properlyif one or more of the TPMS sensorsare missing or inoperable. Whenthe system detects a malfunction,the low tire pressure warning lightflashes for about one minute andthen stays on for the remainder ofthe ignition cycle. A DIC warningmessage also displays. Themalfunction light and DIC warningmessage come on at each ignitioncycle until the problem is corrected.Some of the conditions that cancause these to come on are:. One of the road tires has been

replaced with the spare tire.The spare tire does not have aTPMS sensor. The malfunctionlight and the DIC messageshould go off after the roadtire is replaced and the sensormatching process is performedsuccessfully. See "TPMS SensorMatching Process" later in thissection.


Vehicle Care 10-71

. The TPMS sensor matchingprocess was not done ornot completed successfullyafter rotating the tires. Themalfunction light and the DICmessage should go off aftersuccessfully completing thesensor matching process.See "TPMS Sensor MatchingProcess" later in this section.

. One or more TPMS sensorsare missing or damaged.The malfunction light andthe DIC message should gooff when the TPMS sensorsare installed and the sensormatching process is performedsuccessfully. See your dealerfor service.

. Replacement tires or wheels donot match the original equipmenttires or wheels. Tires and wheelsother than those recommendedcould prevent the TPMS fromfunctioning properly. See BuyingNew Tires on page 10‑77.

. Operating electronic devices orbeing near facilities using radiowave frequencies similar to theTPMS could cause the TPMSsensors to malfunction.

If the TPMS is not functioningproperly, it cannot detect or signal alow tire condition. See your dealerfor service if the TPMS malfunctionlight and DIC message come onand stay on.

TPMS Sensor MatchingProcess

Each TPMS sensor has a uniqueidentification code. The identificationcode needs to be matched to anew tire/wheel position after rotatingthe vehicle’s tires or replacingone or more of the TPMS sensors.Also, the TPMS sensor matchingprocess should be performed afterreplacing a spare tire with a roadtire containing the TPMS sensor.The malfunction light and the DICmessage should go off at the nextignition cycle. The sensors arematched to the tire/wheel positions,using a TPMS relearn tool, in thefollowing order: driver side front tire,passenger side front tire, passengerside rear tire, and driver side rear.See your dealer for service or topurchase a relearn tool.


10-72 Vehicle Care

There are two minutes to matchthe first tire/wheel position, andfive minutes overall to match allfour tire/wheel positions. If it takeslonger, the matching process stopsand must be restarted.

The TPMS sensor matchingprocess is:

1. Set the parking brake.


3. Press the Remote KeylessEntry (RKE) transmitter's LOCKand UNLOCK buttons at thesame time for approximatelyfive seconds. The horn soundstwice to signal the receiveris in relearn mode and TIRELEARNING ACTIVE messagedisplays on the DIC screen.

If the vehicle does not haveRKE, press the DriverInformation Center (DIC) vehicleinformation button until thePRESS V TO RELEARN TIREPOSITIONS message displays.

The horn sounds twice to signalthe receiver is in relearn modeand TIRE LEARNING ACTIVEmessage displays on the DICscreen.

If the vehicle does not have RKEor DIC buttons, press the tripodometer reset stem located onthe instrument panel cluster untilthe PRESS V TO RELEARNTIRE POSITIONS messagedisplays. The horn soundstwice to signal the receiveris in relearn mode and TIRELEARNING ACTIVE messagedisplays on the DIC screen.

4. Start with the driver sidefront tire.

5. Place the relearn tool againstthe tire sidewall, near the valvestem. Then press the buttonto activate the TPMS sensor.A horn chirp confirms that thesensor identification code hasbeen matched to this tire andwheel position.

6. Proceed to the passengerside front tire, and repeat theprocedure in Step 5.

7. Proceed to the passengerside rear tire, and repeat theprocedure in Step 5.

8. Proceed to the driver side reartire, and repeat the procedurein Step 5. The horn sounds twotimes to indicate the sensoridentification code has beenmatched to the driver side reartire, and the TPMS sensormatching process is no longeractive. The TIRE LEARNINGACTIVE message on the DICdisplay screen goes off.

9. Turn the ignition switch toLOCK/OFF.

10. Set all four tires to therecommended air pressurelevel as indicated on the Tireand Loading Information label.


Vehicle Care 10-73

Tire InspectionWe recommend that youregularly inspect the vehicle'stires, including the spare tire,if the vehicle has one, for signsof wear or damage at least oncea month.

Always remove the tires if anyof the following statementsare true:. You can see the indicators at

three or more places aroundthe tire.

. You can see cord or fabricshowing through the tire'srubber.

. The tread or sidewall iscracked, cut, or snaggeddeep enough to show cordor fabric.

. The tire has a bump, bulge,or split.

. The tire has a puncture, cut,or other damage that cannotbe repaired well because ofthe size or location of thedamage.

Tire RotationTires should be rotated every12 000 km (7,500 miles).See Scheduled Maintenance onpage 11‑2.

The purpose of a regular tirerotation is to achieve a uniformwear for all tires on the vehicle.This will ensure that your vehiclecontinues to perform most like itdid when the tires were new.

Any time you notice unusualwear, rotate your tires as soonas possible and check wheelalignment. Also check fordamaged tires or wheels.

See When It Is Time for NewTires on page 10‑76 and WheelReplacement on page 10‑82.

If your vehicle has dual rearwheels, also see Dual TireRotation on page 10‑75.

If your vehicle has single rearwheels and the tread design forthe front tires is the same asthe rear tires, use the rotationpattern shown here whenrotating the tires.


10-74 Vehicle Care

If your vehicle has dual rearwheels and the tread design forthe front tires is the same as therear tires, always use one of thecorrect rotation patterns shownhere when rotating the tires.

If your vehicle has dual rearwheels and the tread design forthe front tires is different fromthe dual rear tires, always usethe correct rotation patternshown here when rotating thetires.

The dual tires are rotated as apair, and the inside rear tiresbecome the outside rear tires.

When you install dual wheels,be sure the vent holes in theinner and outer wheels on eachside are lined up.

After the tires have beenrotated, adjust the front and rearinflation pressures as shown onthe Tire and Loading Informationlabel. See Tire Pressure onpage 10‑66 and Vehicle LoadLimits on page 9‑25.

Make certain that all wheelnuts are properly tightened.See “Wheel Nut Torque” underCapacities and Specifications onpage 12‑2.


Vehicle Care 10-75

{ WARNING

Rust or dirt on a wheel, or onthe parts to which it is fastened,can make wheel nuts becomeloose after time. The wheel couldcome off and cause an accident.When changing a wheel, removeany rust or dirt from places wherethe wheel attaches to the vehicle.In an emergency, use a cloth or apaper towel to do this; but be sureto use a scraper or wire brushlater, if needed, to get all the rustor dirt off. See If a Tire Goes Flaton page 10‑84.

Lightly coat the center of thewheel hub with wheel bearinggrease after a wheel change ortire rotation to prevent corrosionor rust build-up. Do not getgrease on the flat wheelmounting surface or onthe wheel nuts or bolts.

If your vehicle has a TirePressure Monitor System(TPMS), reset the TPMSsensors after rotating the tires.See Tire Pressure MonitorOperation on page 10‑69.

Make sure the spare tire, if yourvehicle has one, is storedsecurely. Push, pull, and thentry to rotate or turn the tire.If it moves, tighten the cable.See “Storing a Flat or SpareTire and Tools” under TireChanging on page 10‑86.

Dual Tire RotationWhen the vehicle is new,or whenever a wheel, wheelbolt or wheel nut is replaced,check the wheel nut torqueafter 160, 1 600 and 10 000 km(100, 1,000 and 6,000 miles) ofdriving. For proper torque andwheel nut tightening information,see “Removing the Spare Tire andTools” under Tire Changing onpage 10‑86.


10-76 Vehicle Care

The outer tire on a dual wheelsetup generally wears faster thanthe inner tire. Your tires will wearmore evenly and last longer if yourotate the tires periodically, see TireInspection on page 10‑73 and TireRotation on page 10‑73. Also seeScheduled Maintenance onpage 11‑2.

{ WARNING

If you operate your vehicle with atire that is badly underinflated, thetire can overheat. An overheatedtire can lose air suddenly or catchfire. You or others could beinjured. Be sure all tires (includingthe spare) are properly inflated.

See Tire Pressure on page 10‑66,for information on proper tireinflation.

When It Is Time for NewTiresVarious factors, such asmaintenance, temperatures,driving speeds, vehicle loading,and road conditions influencewhen you need new tires.

One way to tell when it is time fornew tires is to check the treadwearindicators, which appear when the

tires have only 1.6 mm (1/16 in)or less of tread remaining.Some commercial truck tires maynot have treadwear indicators.See Tire Inspection on page 10‑73and Tire Rotation on page 10‑73for additional information.

The rubber in tires ages over time.This is also true for the spare tire,if the vehicle has one, even if it isnot being used. Multiple conditionsaffect how fast this aging takesplace, including temperatures,loading conditions, and inflationpressure maintenance. Tires willtypically need to be replaced due towear before they may need to bereplaced due to age. Consult the tiremanufacturer for more informationon when tires should be replaced.


Vehicle Care 10-77

Vehicle Storage

Tires age when stored normallymounted on a parked vehicle. Parka vehicle that will be stored for atleast a month in a cool, dry, cleanarea away from direct sunlight toslow aging. This area should befree of grease, gasoline or othersubstances that can deterioraterubber.

Parking for an extended periodcan cause flat spots on the tiresthat may result in vibrations whiledriving. When storing a vehicle forat least a month, remove the tiresor raise the vehicle to reduce theweight from the tires.

Buying New TiresGM has developed and matchedspecific tires for the vehicle.The original equipment tiresinstalled on the vehicle, whenit was new, were designed to meetGeneral Motors Tire PerformanceCriteria Specification (TPC Spec)system rating. If you needreplacement tires, GM stronglyrecommends that you get tireswith the same TPC Spec rating.This way, the vehicle will continueto have tires that are designed togive the same performance andvehicle safety, during normal use,as the original tires.

GM's exclusive TPC Spec systemconsiders over a dozen criticalspecifications that impact theoverall performance of thevehicle, including brake systemperformance, ride and handling,traction control, and tire pressuremonitoring performance. GM's TPCSpec number is molded onto thetire's sidewall near the tire size.If the tires have an all‐seasontread design, the TPC specnumber will be followed by anMS for mud and snow. See TireSidewall Labeling on page 10‑58for additional information.


10-78 Vehicle Care

GM recommends replacing tires insets of four. This is because uniformtread depth on all tires will helpkeep the vehicle performing mostlike it did when the tires were new.Replacing less than a full set oftires can affect the braking andhandling performance of the vehicle.See Tire Inspection on page 10‑73and Tire Rotation on page 10‑73 forinformation on proper tire rotation.

{ WARNING

Tires could explode duringimproper service. Attempting tomount or dismount a tire couldcause injury or death. Only yourdealer or authorized tire servicecenter should mount or dismountthe tires.

{ WARNING

Mixing tires could cause youto lose control while driving.If you mix tires of different sizes,brands, or types (radial andbias-belted tires), the vehiclemight not handle properly, andyou could have a crash. Usingtires of different sizes, brands,or types could also causedamage to the vehicle. Be sureto use the same size, brand,and type of tires on all wheels.

This vehicle may have a differentsize spare than the road tires(those originally installed on thevehicle). When new, the vehicleincluded a spare tire and wheelassembly with a similar overalldiameter as the vehicle's roadtires and wheels, so it is all rightto drive on it. Because this sparewas developed for use on thevehicle, it will not affect vehiclehandling.

{ WARNING

Using bias-ply tires on thevehicle may cause the wheelrim flanges to develop cracksafter many miles of driving.A tire and/or wheel could failsuddenly and cause a crash.Use only radial-ply tires withthe wheels on the vehicle.

If you must replace the vehicle'stires with those that do not havea TPC Spec number, make surethey are the same size, load range,speed rating, and construction type(radial and bias‐belted tires) as thevehicle's original tires.


Vehicle Care 10-79

Vehicles that have a tire pressuremonitoring system may give aninaccurate low‐pressure warningif non‐TPC Spec-rated tires areinstalled on the vehicle. Non‐TPCSpec-rated tires may give alow‐pressure warning that ishigher or lower than the properwarning level you would get withTPC Spec-rated tires. See TirePressure Monitor System onpage 10‑68.

The vehicle's original equipmenttires are listed on the Tire andLoading Information label. SeeVehicle Load Limits on page 9‑25for more information about the Tireand Loading Information label andits location on the vehicle.

Different Size Tires andWheelsIf you add wheels or tires that area different size than the originalequipment wheels and tires, thiscould affect the way the vehicleperforms, including its braking,ride and handling characteristics,stability, and resistance to rollover.Additionally, if the vehicle haselectronic systems such as antilockbrakes, rollover airbags, tractioncontrol, and electronic stabilitycontrol, the performance of thesesystems can be affected.

{ WARNING

If different sized wheels are used,there may not be an acceptablelevel of performance and safetyif tires not recommended forthose wheels are selected.This increases the chanceof a crash and serious injury.Only use GM specific wheeland tire systems developedfor the vehicle, and have themproperly installed by a GMcertified technician.

See Buying New Tires onpage 10‑77 and Accessoriesand Modifications on page 10‑3for additional information.


10-80 Vehicle Care

Uniform Tire QualityGradingQuality grades can be foundwhere applicable on the tiresidewall between tread shoulderand maximum section width.For example:

Treadwear 200 Traction AATemperature A

The following information relatesto the system developed by theUnited States National HighwayTraffic Safety Administration(NHTSA), which grades tiresby treadwear, traction, andtemperature performance.This applies only to vehiclessold in the United States.The grades are molded on thesidewalls of most passenger cartires. The Uniform Tire Quality

Grading (UTQG) systemdoes not apply to deeptread, winter-type snow tires,space-saver, or temporary usespare tires, tires with nominalrim diameters of 10 to 12 inches(25 to 30 cm), or to somelimited-production tires.

While the tires available onGeneral Motors passengercars and light trucks may varywith respect to these grades,they must also conform tofederal safety requirements andadditional General Motors TirePerformance Criteria (TPC)standards.

All Passenger Car Tires MustConform to Federal SafetyRequirements In Addition ToThese Grades.

Treadwear

The treadwear grade is acomparative rating basedon the wear rate of the tirewhen tested under controlledconditions on a specifiedgovernment test course.For example, a tire graded150 would wear one and ahalf (1½) times as well onthe government course asa tire graded 100. The relativeperformance of tires dependsupon the actual conditions oftheir use, however, and maydepart significantly from thenorm due to variations indriving habits, service practicesand differences in roadcharacteristics and climate.


Vehicle Care 10-81

Traction – AA, A, B, C

The traction grades, fromhighest to lowest, are AA, A, B,and C. Those grades representthe tire's ability to stop onwet pavement as measuredunder controlled conditionson specified governmenttest surfaces of asphalt andconcrete. A tire marked C mayhave poor traction performance.Warning: The traction gradeassigned to this tire is basedon straight-ahead brakingtraction tests, and does notinclude acceleration, cornering,hydroplaning, or peak tractioncharacteristics.

Temperature – A, B, C

The temperature gradesare A (the highest), B, and C,representing the tire's resistanceto the generation of heat and itsability to dissipate heat when

tested under controlledconditions on a specifiedindoor laboratory test wheel.Sustained high temperature cancause the material of the tire todegenerate and reduce tire life,and excessive temperaturecan lead to sudden tire failure.The grade C corresponds to alevel of performance which allpassenger car tires must meetunder the Federal Motor SafetyStandard No. 109. Grades Band A represent higher levels ofperformance on the laboratorytest wheel than the minimumrequired by law. Warning: Thetemperature grade for this tireis established for a tire thatis properly inflated and notoverloaded. Excessive speed,underinflation, or excessiveloading, either separately or incombination, can cause heatbuildup and possible tire failure.

Wheel Alignment and TireBalanceThe tires and wheels on the vehiclewere aligned and balanced carefullyat the factory to give the longest tirelife and best overall performance.Adjustments to wheel alignment andtire balancing will not be necessaryon a regular basis. However, if thereis unusual tire wear or the vehiclepulls to one side or the other, thealignment should be checked. If thevehicle vibrates when driving on asmooth road, the tires and wheelsmight need to be rebalanced. Seeyour dealer for proper diagnosis.

Wheel ReplacementReplace any wheel that is bent,cracked, or badly rusted orcorroded. If wheel nuts keep comingloose, the wheel, wheel bolts andwheel nuts should be replaced.If the wheel leaks air, replace it(except some aluminum wheels,which can sometimes be repaired).See your dealer if any of theseconditions exist.

Your dealer will know the kind ofwheel you need.

Each new wheel should havethe same load-carrying capacity,diameter, width, offset and bemounted the same way as theone it replaces.

If you need to replace any of thewheels, wheel bolts, wheel nutsor Tire Pressure Monitor System(TPMS) sensors, replace them onlywith new GM original equipmentparts. This way, you will be sure tohave the right wheel, wheel bolts,wheel nuts, and TPMS sensors forthe vehicle.

{ WARNING

Using the wrong replacementwheels, wheel bolts, or wheelnuts can be dangerous. It couldaffect the braking and handlingof the vehicle. Tires can lose air,and cause loss of control, causinga crash. Always use the correctwheel, wheel bolts, and wheelnuts for replacement.

Notice: The wrong wheelcan also cause problems withbearing life, brake cooling,speedometer or odometercalibration, headlamp aim,bumper height, vehicle groundclearance, and tire or tire chainclearance to the body andchassis.

Whenever a wheel, wheelbolt or wheel nut is replacedon a dual wheel setup, checkthe wheel nut torque after160, 1 600 and 10 000 km(100, 1,000 and 6,000 miles)of driving. For proper torque,see “Wheel Nut Torque” underCapacities and Specifications onpage 12‑2.

See If a Tire Goes Flat onpage 10‑84 for more information.

Used Replacement Wheels

{ WARNING

Replacing a wheel with a usedone is dangerous. How it hasbeen used or how far it has beendriven may be unknown. It couldfail suddenly and cause a crash.When replacing wheels, use anew GM original equipmentwheel.

WARNING (Continued)

Use another type of tractiondevice only if its manufacturerrecommends it for use on thevehicle and tire size combinationand road conditions. Followthat manufacturer's instructions.To help avoid damage to thevehicle, drive slowly, readjust,or remove the device if it iscontacting the vehicle, and donot spin the vehicle's wheels.

If you do find traction devices thatwill fit, install them on the reartires.

Notice: If the vehicle does nothave dual wheels and has atire size other than P265/65R18,P275/55R20, LT265/70R17, LT265/70R18, LT265/60R20, P285/50R20,P285/45R22, or 285/45R22, usetire chains only where legal andonly when you must. Use chainsthat are the proper size for thetires. Install them on the tiresof the rear axle. Do not usechains on the tires of the frontaxle. Tighten them as tightly aspossible with the ends securelyfastened. Drive slowly andfollow the chain manufacturer'sinstructions. If you can hear thechains contacting the vehicle,stop and retighten them. If thecontact continues, slow downuntil it stops. Driving too fast orspinning the wheels with chainson will damage the vehicle.


10-84 Vehicle Care

If a Tire Goes FlatIt is unusual for a tire to blowoutwhile you are driving, especially ifyou maintain your vehicle's tiresproperly. If air goes out of a tire,it is much more likely to leak outslowly. But if you should ever havea blowout, here are a few tips aboutwhat to expect and what to do:

If a front tire fails, the flat tirecreates a drag that pulls the vehicletoward that side. Take your footoff the accelerator pedal and gripthe steering wheel firmly. Steer tomaintain lane position, and thengently brake to a stop, well off theroad, if possible.

A rear blowout, particularly on acurve, acts much like a skid andmay require the same correctionyou would use in a skid. In any rearblowout remove your foot from the

accelerator pedal. Get the vehicleunder control by steering the wayyou want the vehicle to go. It maybe very bumpy and noisy, but youcan still steer. Gently brake to astop, well off the road, if possible.

{ WARNING

Driving on a flat tire will causepermanent damage to the tire.Re-inflating a tire after it hasbeen driven on while severelyunderinflated or flat may causea blowout and a serious crash.Never attempt to re-inflate a tirethat has been driven on whileseverely underinflated or flat.Have your dealer or an authorizedtire service center repair orreplace the flat tire as soonas possible.

{ WARNING

Lifting a vehicle and gettingunder it to do maintenance orrepairs is dangerous without theappropriate safety equipment andtraining. If a jack is provided withthe vehicle, it is designed only forchanging a flat tire. If it is used foranything else, you or others couldbe badly injured or killed if thevehicle slips off the jack. If a jackis provided with the vehicle, onlyuse it for changing a flat tire.

If a tire goes flat, the next partshows how to use the jackingequipment to change a flat tiresafely.


Vehicle Care 10-85

If a tire goes flat, avoid further tireand wheel damage by driving slowlyto a level place, well off the road,if possible. Turn on the hazardwarning flashers. See HazardWarning Flashers on page 6‑5.

{ WARNING

Changing a tire can bedangerous. The vehicle canslip off the jack and roll overor fall on you or other people.You and they could be badlyinjured or even killed. Find a levelplace to change your tire. To helpprevent the vehicle from moving:

1. Set the parking brake firmly.

2. Put an automatictransmission shift lever inP (Park), or shift a manualtransmission to 1 (First) orR (Reverse).

Full-Size Spare TireYour vehicle, when new, had afully-inflated spare tire. A sparetire may lose air over time, socheck its inflation pressure regularly.See Tire Pressure on page 10‑66and Vehicle Load Limits onpage 9‑25 for information regardingproper tire inflation and loading yourvehicle. For instruction on how toremove, install or store a spare tire,see “Removing the Flat Tire andInstalling the Spare” and “Storing aFlat or Spare Tire and Tools” underTire Changing on page 10‑86.

Notice: If the vehicle hasfour-wheel drive and the differentsize spare tire is installed on thevehicle, do not drive in four-wheeldrive until you can have yourflat tire repaired and/or replaced.You could damage the vehicle,and the repair costs would notbe covered by your warranty.Never use four-wheel drive whenthe different size spare tire isinstalled on the vehicle.

Your vehicle may have a differentsize spare tire than the road tiresoriginally installed on your vehicle.This spare tire was developed foruse on your vehicle, so it is all rightto drive on it. If your vehicle hasfour-wheel drive and the differentsize spare tire is installed, keepthe vehicle in two-wheel drive.

After installing the spare tire on yourvehicle, you should stop as soon aspossible and make sure the sparetire is correctly inflated. Have thedamaged or flat road tire repairedor replaced as soon as you canand installed back onto your vehicle.This way, the spare tire will beavailable in case you need it again.

Do not mix tires and wheels ofdifferent sizes, because they willnot fit. Keep your spare tire and itswheel together. If your vehicle hasa spare tire that does not matchyour vehicle's original road tiresand wheels in size and type, do notinclude the spare in the tire rotation.

Jump StartingFor more information about thevehicle battery, see Battery onpage 10‑34.


If the vehicle's battery (or batteries)has run down, you may want to useanother vehicle and some jumpercables to start your vehicle. Be sureto use the following steps to do itsafely.

{ WARNING

Batteries can hurt you. They canbe dangerous because:

. They contain acid that canburn you.

. They contain gas that canexplode or ignite.

. They contain enoughelectricity to burn you.

If you do not follow these stepsexactly, some or all of thesethings can hurt you.

Notice: Ignoring these stepscould result in costly damageto the vehicle that would not becovered by the warranty.

Trying to start the vehicle bypushing or pulling it will notwork, and it could damage thevehicle.

1. Check the other vehicle. It musthave a 12-volt battery with anegative ground system.

Notice: Only use a vehiclethat has a 12-volt system witha negative ground for jumpstarting. If the other vehicle doesnot have a 12-volt system with anegative ground, both vehiclescan be damaged.

2. If you have a vehicle with adiesel engine with two batteries,you should know before youbegin that, especially in coldweather, you may not be ableto get enough power from asingle battery in another vehicleto start your diesel engine.If your vehicle has more thanone battery, using the batterythat is closer to the starter willreduce electrical resistance.This is located on the passengerside, in the rear of the enginecompartment.


Vehicle Care 10-99

3. Get the vehicles close enoughso the jumper cables can reach,but be sure the vehicles are nottouching each other. If they are,it could cause an unwantedground connection. You wouldnot be able to start your vehicle,and the bad grounding coulddamage the electrical systems.

To avoid the possibility of thevehicles rolling, set the parkingbrake firmly on both vehiclesinvolved in the jump startprocedure. Put the automatictransmission in P (Park) or amanual transmission in Neutralbefore setting the parking brake.If you have a four-wheel-drivevehicle, be sure the transfercase is in a drive gear, not inNeutral.

Notice: If the radio or otheraccessories are left on duringthe jump starting procedure, theycould be damaged. The repairs

would not be covered by thewarranty. Always turn off theradio and other accessorieswhen jump starting the vehicle.

4. Turn off the ignition on bothvehicles. Unplug unnecessaryaccessories plugged into thecigarette lighter or the accessorypower outlets. Turn off the radioand all the lamps that are notneeded. This will avoid sparksand help save both batteries.And it could save the radio!

5. Open the hood on the othervehicle and locate thepositive (+) and negative (−)terminal locations on thatvehicle.

The positive (+) terminal, islocated under a red plasticcover at the positive batterypost. To uncover the positive (+)terminal, open the red plasticcover.

If your vehicle has a gasolineengine, the remote negative (−)terminal is a stud located on theright front of the engine, wherethe negative battery cableattaches.

If your vehicle has a dieselengine, the remote negative (−)terminal is the negative (−) poston the auxiliary battery on thedriver side of the enginecompartment.

WARNING (Continued)

Be sure the battery has enoughwater. You do not need to addwater to the battery installed inyour new vehicle. But if a batteryhas filler caps, be sure the rightamount of fluid is there. If it is low,add water to take care of thatfirst. If you do not, explosivegas could be present.

Battery fluid contains acid thatcan burn you. Do not get it onyou. If you accidentally get it inyour eyes or on your skin, flushthe place with water and getmedical help immediately.

{ WARNING

Fans or other moving engineparts can injure you badly. Keepyour hands away from movingparts once the engine is running.

6. Check that the jumper cablesdo not have loose or missinginsulation. If they do, you couldget a shock. The vehicles couldbe damaged too.

Before you connect the cables,here are some basic things youshould know. Positive (+) will goto positive (+) or to a remotepositive (+) terminal if the vehiclehas one. Negative (−) will go to aheavy, unpainted metal enginepart or to a remote negative (−)terminal if the vehicle has one.

Do not connect positive (+) tonegative (−) or you will get ashort that would damage thebattery and maybe other partstoo. And do not connect thenegative (−) cable to thenegative (−) terminal on thedead battery because thiscan cause sparks.

Sheet Metal Damage

If the vehicle is damaged andrequires sheet metal repair orreplacement, make sure the bodyrepair shop applies anti-corrosionmaterial to parts repaired orreplaced to restore corrosionprotection.

Original manufacturer replacementparts will provide the corrosionprotection while maintaining thevehicle warranty.

Finish Damage

Any stone chips, fractures or deepscratches in the finish should berepaired right away. Bare metal willcorrode quickly and may developinto major repair expense.

Minor chips and scratches can berepaired with touch-up materialsavailable from your dealer. Largerareas of finish damage can becorrected in your dealer's bodyand paint shop.

Chemicals used for ice and snowremoval and dust control can collecton the underbody. If these are notremoved, corrosion and rust candevelop on the underbody partssuch as fuel lines, frame, floor pan,and exhaust system even thoughthey have corrosion protection.

At least every spring, flush thesematerials from the underbodywith plain water. Clean any areaswhere mud and debris can collect.Dirt packed in close areas of theframe should be loosened beforebeing flushed. Your dealer or anunderbody car washing systemcan do this.


10-112 Vehicle Care

Underbody Maintenance

Chemicals used for ice and snowremoval and dust control can collecton the underbody. If these are notremoved, corrosion and rust candevelop on the underbody partssuch as fuel lines, frame, floor pan,and exhaust system even thoughthey have corrosion protection.

At least every spring, flush thesematerials from the underbodywith plain water. Clean any areaswhere mud and debris can collect.Dirt packed in close areas of theframe should be loosened beforebeing flushed. Your dealer or anunderbody car washing systemcan do this.

Chemical Paint Spotting

Some weather and atmosphericconditions can create a chemicalfallout. Airborne pollutants can fallupon and attack painted surfaceson the vehicle. This damage cantake two forms: blotchy, ring-shapeddiscolorations, and small, irregulardark spots etched into the paintsurface.

Although no defect in the paint jobcauses this, we will repair, at nocharge to the owner, the surfacesof new vehicles damaged by thisfallout condition within 12 monthsor 20 000 km (12,000miles) ofpurchase, whichever occurs first.

Interior CareThe interior will continue to lookits best if it is cleaned often. Dustand dirt can accumulate on theupholstery and cause damageto the carpet, fabric, leather, andplastic surfaces. Stains should beremoved quickly as extreme heatcould cause them to set rapidly.

Lighter colored interiors mayrequire more frequent cleaning.Newspapers and garments that cantransfer color to home furnishingscan also transfer color to theinterior.

Remove dust from small buttonsand knobs with a small brush withsoft bristles.


Vehicle Care 10-113

Your dealer has products forcleaning the interior. When cleaningthe interior, only use cleanersspecifically designed for thesurfaces that are being cleaned.Permanent damage can resultfrom using cleaners on surfacesfor which they were not intended.Apply the cleaner directly to thecleaning cloth to prevent over-spray.Remove any accidental over-sprayfrom other surfaces immediately.

Notice: Using abrasive cleanerswhen cleaning glass surfaces onthe vehicle, could scratch theglass and/or cause damage tothe rear window defogger. Whencleaning the glass on the vehicle,use only a soft cloth and glasscleaner.

Cleaners can contain solvents thatcan become concentrated in theinterior. Before using cleaners,read and adhere to all safetyinstructions on the label. Whilecleaning the interior, maintainadequate ventilation by openingthe doors and windows.

Do not clean the interior using thefollowing cleaners or techniques:. Never use a knife or any other

sharp object to remove a soilfrom any interior surface.

. Never use a stiff brush. It cancause damage to the interiorsurfaces.

. Never apply heavy pressure orrub aggressively with a cleaningcloth. Use of heavy pressure candamage the interior and doesnot improve the effectivenessof soil removal.

. Use only mild, neutral-pH soaps.Avoid laundry detergentsor dishwashing soaps withdegreasers. Using too muchsoap will leave a residue thatleaves streaks and attractsdirt. For liquid cleaners, about20 drops per 3.78 L (1 gal) ofwater is a good guide.

. Do not heavily saturate theupholstery while cleaning.

. Cleaners that contain solventscan damage the interior.


10-114 Vehicle Care

Fabric/Carpet

Use a vacuum cleaner with a softbrush attachment to remove dustand loose dirt. A canister vacuumwith a beater bar in the nozzlemay only be used on floor carpetand carpeted floor mats. For soils,always try to remove them first withplain water or club soda. Beforecleaning, gently remove as muchof the soil as possible using oneof the following techniques:. For liquids: gently blot the

remaining soil with a papertowel. Allow the soil to absorbinto the paper towel until nomore can be removed.

. For solid dry soils: remove asmuch as possible and thenvacuum.

To clean:

1. Saturate a lint-free, clean whitecloth with water or club soda.

2. Remove excess moisture.

3. Start on the outside edge of thesoil and gently rub toward thecenter. Continue cleaning, usinga clean area of the cloth eachtime it becomes soiled.

4. Continue to gently rub thesoiled area.

5. If the soil is not completelyremoved, use a mild soapsolution and repeat the cleaningprocess that was used with plainwater.

If any of the soil remains, acommercial fabric cleaner or spotlifter may be necessary. Test a smallhidden area for colorfastness beforeusing a commercial upholsterycleaner or spot lifter. If the locallycleaned area gives any impressionthat a ring formation may result,clean the entire surface.

A paper towel can be used to blotexcess moisture from the fabric orcarpet after the cleaning process.

Leather/Leatherette

Leather, and lighter colored leatherin particular, will need more frequentcleaning to prevent the buildup ofdust, dirt, and colors transferredfrom other items so that these donot become permanent stains.

To remove dust, a soft clothdampened with water can be used.If a more thorough cleaning isnecessary, a soft cloth dampenedwith a mild soap solution canbe used. Your dealer has a GMapproved leather cleaner availablethat provides superior cleaningperformance when used regularlyon finished automotive leathers.Allow the leather to dry naturally.Do not use heat, steam, spot liftersor spot removers, or shoe polish onleather. Many commercial leathercleaners and coatings that aresold to preserve and protect leathermay permanently change theappearance and feel of the leatherand are not recommended.


Vehicle Care 10-115

Do not use silicone or wax-basedproducts, or those containingorganic solvents to clean theinterior because they can alterthe appearance by increasing thegloss in a non-uniform manner.

Instrument Panel, Vinyl andother Plastic Surfaces

To remove dust, a soft clothdampened with water can beused. If a more thorough cleaningis necessary, a clean soft clothdampened with a mild soap solutioncan be used to gently remove dustand dirt. Never use spot liftersor removers on plastic surfaces.Many commercial cleaners andcoatings that are sold to preserveand protect soft plastic surfacesmay permanently change theappearance and feel of the interiorand are not recommended. Do notuse silicone or wax-based products,or those containing organic solvents

Collision Damage Repair(U.S. and Canada)If the vehicle is involved in acollision and it is damaged, havethe damage repaired by a qualifiedtechnician using the properequipment and quality replacementparts. Poorly performed collisionrepairs diminish the vehicle resalevalue, and safety performance canbe compromised in subsequentcollisions.

Collision Parts

Genuine GM Collision parts are newparts made with the same materialsand construction methods as theparts with which the vehicle wasoriginally built. Genuine GMCollision parts are the best choice toensure that the vehicle's designedappearance, durability, and safetyare preserved. The use of GenuineGM parts can help maintain the GMNew Vehicle Limited Warranty.



Recycled original equipmentparts may also be used for repair.These parts are typically removedfrom vehicles that were total lossesin prior crashes. In most cases,the parts being recycled are fromundamaged sections of the vehicle.A recycled original equipment GMpart may be an acceptable choiceto maintain the vehicle's originallydesigned appearance and safetyperformance; however, the history ofthese parts is not known. Such partsare not covered by the GM NewVehicle Limited Warranty, and anyrelated failures are not covered bythat warranty.

Aftermarket collision parts arealso available. These are made bycompanies other than GM and maynot have been tested for the vehicle.

As a result, these parts may fitpoorly, exhibit premature durability/corrosion problems, and may notperform properly in subsequentcollisions. Aftermarket parts are notcovered by the GM New VehicleLimited Warranty, and any vehiclefailure related to such parts is notcovered by that warranty.

Repair Facility

GM also recommends that youchoose a collision repair facility thatmeets your needs before you everneed collision repairs. The dealermay have a collision repair centerwith GM-trained technicians andstate‐of‐the‐art equipment, or beable to recommend a collisionrepair center that has GM-trainedtechnicians and comparableequipment.

Insuring The Vehicle

Protect your investment in theGM vehicle with comprehensiveand collision insurance coverage.There are significant differencesin the quality of coverage affordedby various insurance policy terms.Many insurance policies providereduced protection to the GMvehicle by limiting compensationfor damage repairs by usingaftermarket collision parts. Someinsurance companies will notspecify aftermarket collision parts.When purchasing insurance, werecommend that you ensure thatthe vehicle will be repaired withGM original equipment collisionparts. If such insurance coverageis not available from your currentinsurance carrier, consider switchingto another insurance carrier.



If the vehicle is leased, the leasingcompany may require you to haveinsurance that ensures repairs withGenuine GM Original EquipmentManufacturer (OEM) parts orGenuine Manufacturer replacementparts. Read the lease carefully, asyou may be charged at the end ofthe lease for poor quality repairs.

If a Crash Occurs

If there has been an injury, callemergency services for help. Do notleave the scene of a crash until allmatters have been taken care of.Move the vehicle only if its positionputs you in danger, or you areinstructed to move it by a policeofficer.

Give only the necessary informationto police and other parties involvedin the crash.

For emergency towing seeRoadside Assistance Program(U.S. and Canada) on page 13‑8or Roadside Assistance Program(Mexico) on page 13‑10.

Gather the following information:. Driver name, address, and

telephone number.. Driver license number.. Owner name, address, and

telephone number.. Vehicle license plate number.. Vehicle make, model, and

model year.. Vehicle Identification

Number (VIN).. Insurance company and policy

number.. General description of the

damage to the other vehicle.

Choose a reputable repair facilitythat uses quality replacement parts.See “Collision Parts” earlier in thissection.

If the airbag has inflated, see WhatWill You See After an AirbagInflates? on page 3‑35.

Managing the Vehicle DamageRepair Process

In the event that the vehicle requiresdamage repairs, GM recommendsthat you take an active role in itsrepair. If you have a pre-determinedrepair facility of choice, take thevehicle there, or have it towedthere. Specify to the facility that anyrequired replacement collision partsbe original equipment parts, eithernew Genuine GM parts or recycledoriginal GM parts. Remember,recycled parts will not be coveredby the GM vehicle warranty.

Insurance pays the bill for the repair,but you must live with the repair.Depending on your policy limits,your insurance company mayinitially value the repair usingaftermarket parts. Discuss this withthe repair professional, and insiston Genuine GM parts. Remember,if the vehicle is leased, you maybe obligated to have the vehiclerepaired with Genuine GM parts,even if your insurance coveragedoes not pay the full cost.



If another party's insurancecompany is paying for the repairs,you are not obligated to accepta repair valuation based on thatinsurance company's collisionpolicy repair limits, as you have nocontractual limits with that company.In such cases, you can have controlof the repair and parts choicesas long as the cost stays withinreasonable limits.

Vehicle DataRecording andPrivacyThis GM vehicle has a number ofsophisticated computers that recordinformation about the vehicle’sperformance and how it is driven.For example, the vehicle usescomputer modules to monitor andcontrol engine and transmissionperformance, to monitor theconditions for airbag deploymentand deploy airbags in a crash, and,if so equipped, to provide antilockbraking to help the driver control thevehicle. These modules may storedata to help the dealer technicianservice the vehicle. Some modulesmay also store data about how youoperate the vehicle, such as rate offuel consumption or average speed.These modules may also retain theowner’s personal preferences, suchas radio pre-sets, seat positions,and temperature settings.

Event Data RecordersThis vehicle has an Event DataRecorder (EDR). The main purposeof an EDR is to record, in certaincrash or near crash-like situations,such as an airbag deployment orhitting a road obstacle, data thatwill assist in understanding howa vehicle's systems performed.The EDR is designed to record datarelated to vehicle dynamics andsafety systems for a short period oftime, typically 30 seconds or less.The EDR in this vehicle is designedto record such data as:. How various systems in the

vehicle were operating.. Whether or not the driver and

passenger safety belts werebuckled/fastened.

. How far, if at all, the driver waspressing the accelerator and/orbrake pedal.

. How fast the vehicle wastraveling.



This data can help provide a betterunderstanding of the circumstancesin which crashes and injuries occur.

Important: EDR data is recordedby the vehicle only if a non-trivialcrash situation occurs; no data isrecorded by the EDR under normaldriving conditions and no personaldata (e.g., name, gender, age,and crash location) is recorded.However, other parties, such aslaw enforcement, could combinethe EDR data with the type ofpersonally identifying dataroutinely acquired during acrash investigation.

To read data recorded by an EDR,special equipment is required, andaccess to the vehicle or the EDR isneeded. In addition to the vehiclemanufacturer, other parties, such as

law enforcement, that have thespecial equipment, can read theinformation if they have access tothe vehicle or the EDR.

GM will not access this data orshare it with others except: with theconsent of the vehicle owner or,if the vehicle is leased, with theconsent of the lessee; in responseto an official request by police orsimilar government office; as partof GM's defense of litigation throughthe discovery process; or, asrequired by law. Data that GMcollects or receives may also beused for GM research needs or maybe made available to others forresearch purposes, where a need isshown and the data is not tied to aspecific vehicle or vehicle owner.

OnStar®

If the vehicle is equipped withan active OnStar system, thatsystem may also record data incrash or near crash‐like situations.The OnStar Terms and Conditionsprovides information on datacollection and use and is availablein the OnStar glove box kit,at www.onstar.com (U.S.) orwww.onstar.ca (Canada), orby pressing theQ button andspeaking to an advisor.

Navigation SystemIf the vehicle has a navigationsystem, use of the system mayresult in the storage of destinations,addresses, telephone numbers, andother trip information. Refer to thenavigation system operating manualfor information on stored data andfor deletion instructions.



Radio FrequencyIdentification (RFID)RFID technology is used in somevehicles for functions such as tirepressure monitoring and ignitionsystem security, as well as inconnection with conveniencessuch as key fobs for remote doorlocking/unlocking and starting, andin-vehicle transmitters for garagedoor openers. RFID technology inGM vehicles does not use or recordpersonal information or link withany other GM system containingpersonal information.

Radio FrequencyStatementThis vehicle has systems thatoperate on a radio frequency thatcomply with Part 15 of the FederalCommunications Commission (FCC)rules and with Industry CanadaStandards RSS‐210/220/310.

Operation is subject to the followingtwo conditions:

1. The device may not causeinterference.

2. The device must accept anyinterference received, includinginterference that may causeundesired operation of thedevice.

Changes or modifications to anyof these systems by other than anauthorized service facility could voidauthorization to use this equipment.
