Immobilizer Operation

This vehicle is equipped with the
®
PASS-Key III+ (Personalized
Automotive Security System)
Keys, Doors, and Windows
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.
