Immobilizer Operation Your vehicle has a passive theft-deterrent system. The system is automatically armed when the ignition mode transitions to off. The immobilization system is disarmed when the ignition mode transitions to OFF/ACCESSORY or START and a valid transmitter is found in the vehicle. You do not have to manually arm or disarm the system. The security light will come on if there is a problem with arming or disarming the theft-deterrent system. The system has one or more keyless access transmitters that are matched to an immobilizer control unit in your vehicle. Only a correctly matched keyless access transmitter will start the vehicle. If the keyless access transmitter is ever damaged, you may not be able to start your vehicle. When trying to start the vehicle, if the engine does not start and the security light comes on, there may be a problem with your immobilizer system. Press the START button again. 2-26
