Overhaul



Overhaul
During overhaul, if not already done, immobilize and disable the vehicle.

Immobilize Vehicle
Chock wheels and set the parking brake.
Push the P switch to engage park.

Disable Vehicle
Performing either of the two procedures will shut the vehicle off and disable the HV battery pack, SRS airbags, and gasoline fuel pump.

Procedure #1
1. Confirm the status of READY indicator in the instrument cluster.
2. If the READY indicator is illuminated, the vehicle is on and operational. Shut off the vehicle by pushing the power button once.
3. The vehicle is already shut off if the instrument cluster lights and the READY indicator are not illuminated. Do not push the power button the vehicle may start.
4. Remove the electronic key from the key slot.
5. If equipped, disable the smart key button underneath the steering column.
6. Keep the electronic key at least 16 feet (5 meters) away from the vehicle.
7. If the electronic key cannot be removed from the key slot or if the electronic key cannot be found, disconnect the 12-Volt auxiliary battery in the rear cargo area.

Alternate Procedure (power button inaccessible)

Procedure #2
1. Disconnect the 12-Volt auxiliary battery in the rear cargo area.
2. Remove the HEV fuse (20A yellow colored) in the engine compartment junction block. When in doubt, pull all four fuses in the fuse block.

WARNING:
After disabling the vehicle, power is maintained for 90 seconds in the SRS system and 5 minutes in the high voltage electrical system.

If either of the disabling steps above cannot be performed, proceed with caution as there is no assurance that the high voltage electrical system, SRS, or fuel pump are disabled.

Never touch, cut, or open any orange high voltage power cable or high voltage component.
