must also be programmed. Any lost or stolen
transmitters no longer work once the new transmitter
is programmed. Each vehicle can have up to
eight transmitters programmed to it. See RELEARN

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.

Testing the Alarm
1. From inside the vehicle, roll down the window, then
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.
