Immobilizer Operation
This vehicle is equipped with the
PASS-Key®III+ (Personalized Automotive
Security System) theft-deterrent system.
PASS-Key III+ is a passive theft deterrent
system.
The system is automatically armed when
the key is removed from the ignition.
You do not have to manually arm or disarm
the system.
The security light will come on if there is a
problem with arming or disarming the
theft-deterrent system.
If the engine does not start and the security
light comes on, the key may have a
damaged transponder. Turn the ignition off
and try again.
If the engine still does not start, and the
key appears to be undamaged, try another
ignition key. If the engine still does not
start with the other key, the vehicle needs
service. If the vehicle does start, the first
key may be faulty. See your dealer or a
locksmith who can service the PASS-Key III+
to have a new key made.
