Immobilizer Operation
Your vehicle may have a passive theft-deterrent
system. The immobilizer system prevents
your vehicle from being started by unauthorized
persons.
If your vehicle has an immobilizer system, your
vehicle has a special key that works with the
theft-deterrent system. There is a transponder in
the key head that is electronically coded. The
correct key will start the vehicle. An invalid
key immobilizes the engine. The immobilizer
system isolates the power supply to the ignition
system, the fuel pump and the fuel injectors.
The engine immobilizer is activated after the key is
turned to LOCK and removed from the ignition.
The security light located on the top center of the
instrument panel in the secondary information
center will flash when the immobilizer is active.
If the light does not flash after removing the key,
have the system checked by your dealer.
If the immobilizer system does not recognize the
electronic code when the key is turned to START,
the engine will not start and the security indicator
will continue blinking. If your key is ever damaged,
you may not be able to start your vehicle.
