Security Light

The immobilizer light should come

The immobilizer light should come on briefly as the engine is started.

If it does not come on, have the vehicle serviced by your dealer.

If the system is working normally, the indicator light turns off.

If the light stays on and the engine does not start, there could be a problem with the theft-deterrent system. See Immobilizer Operation (Key Access) or Immobilizer Operation (Keyless Access) for more information.

For eAssist vehicles, this light displays in the Driver Information Center (DIC).
