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 key is
removed from the ignition.
The system is automatically
disarmed when the vehicle is
started with the correct key. The key
uses a transponder that matches an
immobilizer control unit in the
vehicle and automatically disarms
the system. Only an authorized key
starts the vehicle. The vehicle may
not start if the key is damaged.
The security light, located in the
instrument panel cluster, comes on
if there is a problem with arming or
disarming the theft-deterrent
system.
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 off and try again.
If the engine still does not start, and
the key appears to be undamaged
or the light continues to stay on, try
another ignition key. If the engine
does not start with the other key, the
vehicle needs service. If the vehicle
does start, the first key may be
damaged. See your dealer who can
service the theft-deterrent system
and have a new key made.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.
