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.
Keys, Doors and Windows
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.
