Do NOT Cut Zones

WARNING: Do NOT cut the fuel lines – cutting fuel lines will releasehydrogen in the fuel lines.

Danger: Do NOT cut the orange high voltage cables. Cutting thesecables can result in serious injury or death.

Warning Level (above 12% of lower flammability limit)

Alarm Level (above 50% of lower flammability limit) – Audible beep

Hydrogen SensorsThere are a total of 7 hydrogen sensors on the Equinox Fuel Cell.

Disabling Propulsion SystemA hood switch is mounted near thehood latch and stops hydrogen flowif the hood of the vehicle is not fullylatched.If the hood is opened while thevehicle is running, high voltagecurrent flow will be disabled, andhydrogen flow through the Fuel CellSystem will shut down.

Disabling PowerPerform each of the following steps todisable the high and low voltageelectrical systems. This includespower to the air bag system.1. Turn the ignition key to the OFF

position.2. Pull the hood release latch. This

interrupts the normal Fuel CellSystem shutdown procedure, disconnects the high voltage powersupply, and stops hydrogen flow to the propulsion system.

3. Remove the 12 volt battery cover and disconnect or cut the 12 voltnegative battery cable.

4. WAIT a minimum of 10 seconds to allow any undeployed air bagreserve energy and high voltage energy to dissipate before cuttinginto the vehicle.

High Voltage Electrical SystemThere are three sources of high voltage power on the vehicle: thebattery, the fuel cell and the regenerative braking system (the ElectricDrive Motor). Regenerative power is not generated when the vehiclehas stopped moving.The high voltage is shut off immediately when an air bag deploys, thehood is opened or the rear crash sensor is activated. When the ignitionis turned OFF, the fuel cell shuts down and its high voltage powerdissipates within minutes.Disconnecting the 12 volt battery removes power from undeployed airbags and provides a secondary interruption of power from the highvoltage battery and fuel cell.

WARNING: Even though high voltage current flow stops when thepower is interrupted, do NOT cut the orange high voltage cablesand/or the High Voltage Power Converter.If an orange cable and/or the High Voltage Power Converter is cut,residual static charge may cause an electrical arc discharge and/orpersonal injury.

Caution: No matter what disablemethod you perform, do NOT cutthe high voltage cables.

No Cut Zones• Hydrogen Tanks• Engine Compartment• Beneath the Passenger Cabin Floor

Note: Disconnect the 12v Battery prior to cutting the rear roof pillarand allow any undeployed airbag reserve energy to dissipate.

After disabling 12 volt power, WAIT a minimum of 10 seconds toallow any undeployed air bag reserve energy and high voltageenergy to dissipate before cutting into the vehicle.
