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 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.
Keys, Doors, and Windows
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. Or, you
may try placing the remote key
in the backup location. See
Remote Key Operation 0 8.
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 under Remote
Key Operation 0 8.
