Vehicle Security
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 vehicle is turned on 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, you may not
be able to start your vehicle.
When trying to start the vehicle, the
security light may come on briefly.
If the vehicle does not start and the security
light stays on, there is a problem with the
system. Turn the vehicle off and try again.
If the vehicle will not turn on or off, and the
remote key appears to be undamaged, try
another remote key. You may also try
placing the remote key in the backup
location. See the owner's manual.
If the vehicle will not turn on or off with
the other remote key or in the backup
location, the vehicle needs service. If the
vehicle does turn on or off, the first remote
key may be faulty. See your dealer.
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 to the Vehicle" in the owner's manual.
Keys, Doors, and Windows
Do not leave the remote key or device that
disarms or deactivates the theft-deterrent
system in the vehicle.
