Testing the Alarm To test the alarm:
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the RKE transmitter.
3. Get out of the vehicle, close the door and wait for
the security light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door.
This should set off the alarm.
While the alarm is set, the power door unlock switch will
not work.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
see Fuses and Circuit Breakers on page 6-106 .
If the alarm does not sound or the headlamps do
not ash, the vehicle should be serviced by your
dealer/retailer. PASS-Key ®

PASS-Key ®
III+ Electronic
Immobilizer Operation Your vehicle has 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.
The system is automatically disarmed when the key is
turned to ON/RUN, ACC/ACCESSORY or START from
the LOCK/OFF position.
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.
When the PASS-Key ®
III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes. If the engine does not start and the security light on
the instrument panel cluster comes on when trying to
start the vehicle, there may be a problem with your
theft-deterrent system. 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. At this time, you
may also want to check the fuse, see Fuses and Circuit
Breakers on page 6-106 . If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the rst key may be faulty. See your
dealer/retailer who can service the PASS-Key ®
III+ to
have a new key made. In an emergency, contact
Roadside Assistance.
It is possible for the PASS-Key ®
III+ decoder to learn
the transponder value of a new or replacement key.
Up to 10 keys may be programmed for the vehicle.
The following procedure is for programming additional
keys only. If all the currently programmed keys are lost or
do not operate, you must see your dealer/retailer or a
locksmith who can service PASS-Key ®
III+ to have keys
made and programmed to the system.
