Immobilizer Operation

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 vehicle is turned off.
The immobilization system is disarmed
when the ignition is on or in accessory
mode and a valid remote key is present in
the vehicle.
The security light in the instrument cluster
comes on if there is a problem with arming
or disarming the theft-deterrent system.
The system has one or more remote keys
matched to an immobilizer control unit in
the vehicle. Only a correctly matched
remote key will start the vehicle. If the
remote key is ever damaged, the vehicle
may not start.
When trying to start the vehicle, the
security light may come 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 off and try again.
If the vehicle will not change ignition
modes, and the remote key appears to be
undamaged, try another remote key. Or, try
placing the remote key into the remote key
pocket located in the center console. See
Starting the Vehicle With a Low remote key
Battery under Remote Key Operation 0 8.
If the ignition mode will not change with
the other remote key or with a remote key
in the remote key pocket, your vehicle
needs service. If the ignition does change
modes, the first remote key may be faulty.
See your dealer who can service the
theft-deterrent system and have a new
remote key programmed to the vehicle.
It is possible for the immobilizer system to
learn new or replacement remote keys. Up
to eight remote keys can be programmed
for the vehicle. To program additional
remote keys, see Programming remote keys
