GM Service Manual Online
For 1990-2009 cars only

This vehicle has a theft-deterrent alarm system.


Object Number: 822610  Size: A1

The security light flashes if a door is open and locked with the power door lock switch.

If this light stays on while the engine is running, the vehicle needs service.

Arming the System

To arm the system:

    • Press on the keyless access transmitter.
    • Open the door and lock the door with the power door lock switch. The security light should flash. Remove the keyless access transmitter from inside the vehicle and close the door. The security light stops flashing and stays on. After 30 seconds, the light should turn off.
        The vehicle can be programmed to automatically lock the doors and arm the theft-deterrent system when you exit the vehicle. See DIC Vehicle Personalization .

If a door or the hatch/trunk is opened without using the keyless access transmitter, the alarm goes off. The horn sounds for two minutes, then goes off to save battery power. The vehicle will not start without a keyless access transmitter present.

The theft-deterrent system does not arm if the driver door is locked with the power door lock switch after the doors are closed.

If the keyless access transmitter is removed from the vehicle while a passenger is in it, have them lock the doors after they are closed. The alarm will not arm, so the passenger will not set it off.

Testing the Alarm

To test the system:

  1. Make sure the trunk lid/hatch is latched.
  2. Lower the window on the driver door.
  3. Manually arm the system.
  4. Close the doors and wait 30 seconds.
  5. Reach through the open window and manually pull the release lever on the floor.
  6. Press the unlock button on the transmitter to turn off the alarm.

If the alarm does not sound, check to see if the horn works. The horn fuse may be blown. See Fuses and Circuit Breakers . If the horn works, but the alarm does not go off, see your dealer/retailer.

Disarming the System

Press the unlock button on the keyless access transmitter or squeeze the door handle sensor while the transmitter is near the vehicle to unlock a door. Unlocking a door any other way sets off the alarm. If the alarm sounds, press the unlock button on the keyless access transmitter to disarm it.

Do not leave the key or device that disarms or deactivates the theft deterrent system in the vehicle.
