GM Service Manual Online
For 1990-2009 cars only

This vehicle may have a theft-deterrent system that activates an alarm if attempts are made to damage or break into the vehicle. The alarm sounds and the lights flash.


Object Number: 2010518  Size: G1

The security light is located on the center of the instrument panel.

Arming the System

To arm the system:

  1. Close all the doors and the liftgate.
  2. Lock the doors and liftgate with the key or Remote Keyless Entry (RKE) transmitter.
  3. The security light comes on solid.

    The system automatically arms after 30 seconds. The security light flashes when the system is armed.

No one should be in the vehicle when the alarm system is armed because unlocking the vehicle from the inside activates the system.

To avoid setting off the alarm make sure all passengers are out of the vehicle and the windows are closed before arming the system.

Disarming the System

To disarm the alarm do one of the following:

    • Unlock the doors with the key.
    • Unlock the doors and liftgate with the RKE transmitter.
    • Start the engine.

Testing the Alarm

To test the alarm:

  1. Open all the windows.
  2. Set the system as described in the previous procedure. The doors and liftgate should be locked with the key or RKE transmitter. Be sure to wait until the security light starts flashing.
  3. Unlock the driver door from the inside. The system should activate the alarm.
  4. Stop the alarm as described in the disarming procedure.
  5. Repeat this operation for the other doors. Also, check that the system is activated when the battery terminal is disconnected and then reconnected.

If the system does not work properly, have it checked by your dealer/retailer.

How the System Alarm is Activated

The system activates the alarm if:

    • A locked door or the liftgate is unlocked or opened without the RKE transmitter.
    • A locked door is unlocked or opened without the key.
    • The liftgate is unlocked or opened with the key.
    • The battery is reconnected.
    • The side windows are tapped or broken.

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