Your vehicle is equipped with the Passlock theft-deterrent system.


Object Number: 807083  Size: A1

This light is located on the instrument panel cluster and will come on for the Passlock theft-deterent system.

Passlock is a passive theft-deterrent system. Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder is tampered with, fuel is disabled.

During normal operation, the security light will go off approximately five seconds after the key is turned to RUN following an engine start.

If the engine stalls and the security light flashes, wait until the light stops flashing before trying to restart the engine. Remember to release the key from START as soon as the engine starts.

If the engine is running and the security light comes on, you will be able to restart the engine if you turn the engine off. However, your Passlock system is not working properly and must be serviced by your retailer. Your vehicle is not protected by Passlock at this time. You may also want to check the fuses, see Fuses and Circuit Breakers . See your retailer for service. Also, see Roadside Assistance Program for more information.
