Immobilizer Operation (Keyless Access)
This vehicle has a passive theft-deterrent system.
The system does not have to be manually armed or disarmed.
The vehicle is automatically immobilized when the ignition control knob is turned to LOCK/OFF.
The immobilization system is disarmed when the ignition control knob is pushed in and a valid transmitter is found in the vehicle.
The security light, located in the instrument panel cluster, comes on if there is a problem with arming or disarming the theft-deterrent system.
One or more keyless access transmitters can be matched to the vehicle's immobilizer control unit.
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, the security light comes on briefly when the ignition is turned on.
If the engine does not start and the security light stays on, there is a problem with the system. Turn the ignition control knob off and try again.
If the ignition control knob does not rotate, and the keyless access transmitter appears to be undamaged, try another keyless access transmitter. Or, you may try placing the transmitter in the transmitter pocket located in the center console. See “Electronic Key Not Detected” under Key and Lock Messages.
If the ignition control knob still does not rotate with the other transmitter, the vehicle needs service. If the ignition control knob does rotate, the first transmitter may be faulty.
See your dealer who can service the theft-deterrent system and have a new keyless access transmitter programmed to the vehicle.
It is possible for the immobilizer system to learn new or replacement keyless access transmitters. Up to four keyless access transmitters can be programmed for the vehicle.
To program additional transmitters, see “Programming Transmitters to the Vehicle” for keyless access under Remote Keyless Entry (RKE) System Operation (Keyless Access) or Remote Keyless Entry (RKE) System Operation (Key Access).
Do not leave the key or device that disarms or deactivates the theft deterrent system in the vehicle.
