Immobilizer Operation
The vehicle has a passive theft-deterrent
system.
The security light comes on in the
instrument cluster if there is a problem with
arming or disarming the theft-deterrent
system. This light also comes on briefly
when the engine is started.
The system is automatically armed when
the ignition is turned off.

when the ignition is turned on or placed in
ACC/ACCESSORY and a valid remote key is
found in the vehicle.
You do not have to manually arm or disarm
the system.
The system has one or more remote keys
that are matched to an immobilizer control
unit in the vehicle. Only a correctly matched
remote key starts the vehicle. The vehicle
may not start if the remote key is damaged.If the engine does not start and the security
light comes on, there may be a problem
with the immobilizer system. Try starting
the vehicle again.
If the vehicle does not start and the remote
key appears to be undamaged, try another
remote key. Or, place the remote key in the
cupholder backup location. See
Remote
Keyless Entry (RKE) System Operation 07.
If the engine still does not start with the
other remote key, or with the remote key in

needs service. If the engine does start, the
first remote key may be faulty. See your
dealer or have a new remote key

replacement remote keys. Up to eight
remote keys can be programmed for the
vehicle. To program additional remote keys,
