your dealer/retailer. All transmitters need to be re-coded
to match the new transmitter.
The lost transmitter no longer works after the new
transmitters are re-coded. The vehicle can have a
maximum of eight transmitters matched to it. See
“Relearn Remote Key” underDIC Operation and
Displays on page 3-48.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
This vehicle has theft-deterrent features, however,
they do not make it impossible to steal.
Theft-Deterrent System
If your vehicle has this
feature, the security light is
located on the instrument
panel cluster.
To activate the theft-deterrent system:
1. Open the door.
2. Lock the door with the transmitter. The security light
should come on and stay on.
3. Close all doors. The security light should go off
after about 30 seconds. The alarm is not armed
until the security light goes off.If a locked door or trunk is opened without using the
key in the driver’s door key cylinder or the transmitter, a
ten second pre-alarm will occur. The horn will chirp and
the lights will ash. If the key is not placed in the ignition
and turned to START or the door is not unlocked by
pressing the unlock button on the transmitter during the
ten second pre-alarm, the alarm will go off. Your vehicle’s
headlamps will ash and the horn will sound for about
30 seconds, then will turn off to save the battery power.
The theft-deterrent system will not activate if the doors
are locked with the vehicle’s key or the manual door
lock. It activates only if the power door lock switch
is used while the door is open or with the transmitter.
You should also remember that you can start your
vehicle with the correct ignition key if the alarm has
been set off.
To avoid setting off the alarm by accident:
Lock the vehicle with the door key after the doors
are closed.
Always unlock a door with the transmitter. Unlocking
a door any other way will set off the alarm.
If you set off the alarm by accident, turn off the alarm by
pressing the unlock button on the transmitter. The alarm
will not stop if you try to unlock a door any other way.
2-28

Testing the Alarm
The alarm can be tested by following these steps:
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
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,
seeFuses and Circuit Breakers on page 5-123
Fuses and Circuit Breakers.
If the alarm does not sound or the headlamps do
not ash, the vehicle should be serviced by your
dealer/retailer.
