Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Theft-Deterrent System
Your vehicle has a theft-deterrent alarm system.
The security light
is located on the
instrument panel
cluster.
If the ignition is off and a door is open, the security light
will ash, reminding you to arm the theft-deterrent
system.
To arm the system, do one of the following:
Press the lock button on the keyless access
transmitter. If the door is closed when the lock button
is pressed, the security light will stay illuminated for
30 seconds. After the security light goes off, the
theft-deterrent system is armed. Pressing the lock
button twice will arm the system immediately.If the vehicle is locked using the keyless access
transmitter and the trunk lid, hood or a door is open
or not closed completely, the security light will ash
for 60 seconds and then turn off. At this time, the
theft-deterrent system is armed but the alarm will not
sound if the trunk lid, hood or door that was not
closed completely is tampered with or opened. The
alarm will sound for the trunk lid, hood or a door that
was completely closed at the time the vehicle was
locked using the keyless access transmitter.
Open the door. Lock the door with the power door
lock switch or lock button on the keyless access
transmitter. The security light should ash. Close the
door. The security light will stop ashing and stay on.
After 30 seconds the light should turn off, the
theft-deterrent system is armed.
Passive Arming, if activated through the vehicle
personalization feature, will arm the system
automatically after you close the door and take at
least one keyless access transmitter with you. The
security light will turn on. After 60 seconds the light
should turn off. The theft-deterrent system is armed.
SeeVehicle Personalization on page 2-47.
If a door, hood, or the trunk is opened without the
keyless access transmitter, the horn will sound for
30 seconds and the lamps will ash for two minutes.
The vehicle cannot be started without a keyless access
transmitter.
2-19

The Theft-Deterrent system will not arm if:
The key is used to lock the driver’s door.
The driver’s door is locked using the power door
lock switch after the doors are closed.
If the vehicle is locked using the keyless access
transmitter and the trunk lid, hood or a door is open or
not closed completely, the security light will ash for
60 seconds and then turn off. At this time, the
theft-deterrent system is armed but the alarm will not
sound if the trunk lid, hood or door that was not closed
completely is tampered with or opened. The alarm
will sound for the trunk lid, hood or a door that was
completely closed at the time the vehicle was locked
using the keyless access transmitter.
The vehicle can be programmed to automatically unlock
the doors and disarm the theft-deterrent system when
you approach the vehicle and the keyless access
transmitter is with you. SeeVehicle Personalization
on page 2-47.
Pressing the unlock button on the keyless access
transmitter or using the key to unlock the driver’s door
disarms the theft-deterrent system. Unlocking a door
any other way while the system is armed will activate
the alarm.
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 switch
or the keyless access transmitter and close the
door. Wait approximately 30 seconds until the
security light goes off.
3. Reach in and open the door using the inside door
handle. The horn will sound and the exterior lamps
will ash.
You can turn off the alarm by pressing the unlock
button on the keyless access transmitter or by starting
the car.
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.
