Content Theft-Deterrent
The security light is
located on the instrument
panel cluster.
To arm the system:
1. Open the door.
2. Lock the door using the power door lock switch with
the door open or the Remote Keyless Entry (RKE)
transmitter. The security light will ash.
3. Close all the doors. The security light will come on
and stay on for approximately 30 seconds.
If a door or the trunk is opened without a key or a
RKE transmitter the horn will sound and the lamps will
ash for about 30 seconds.The theft-deterrent system will not arm if you lock the
doors with a key or use the manual door lock. It arms
only if you use a power door lock with the door open or
the RKE transmitter.
To avoid arming the alarm by accident:
Lock the vehicle with the door key or the manual
door lock.
Always unlock a door with a key or use the RKE
transmitter system. Pressing the unlock button
on the RKE transmitter, or unlocking a door with the
key disarms the content theft-deterrent system.
Unlocking a door any other way will activate
the alarm when a door or the trunk is opened.
If you activate the alarm by accident, unlock the driver’s
door with your key. You can also turn off the alarm
by using the unlock button on the RKE transmitter
system, or by starting the car with a valid key.
Changes or modications made to this system by
other than an authorized service facility could void
authorization to use the theft system.
2-21

Testing the Alarm

get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock or the
RKE system and close the door. Wait 30 seconds
until the security lamp goes off.
3. Reach in and unlock the door using the manual
lock and open the door. The horn will sound and
the hazard lights will ash.
You can turn off the alarm by unlocking the driver’s door
with your key, using the unlock button on the RKE
transmitter or by starting the car with a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown.
To replace the fuse, seeFuses and Circuit Breakers on
page 5-95. If the fuse does not need to be replaced,
you may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft-deterrent system when leaving your vehicle.

2-22

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 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, seeFuses
and Circuit Breakers on page 5-95. 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.
