For 1990-2009 cars only

Your vehicle is equipped with a theft-deterrent alarm system.


Object Number: 806223  Size: A1

With this system, the SECURITY light will flash as you open the door if your ignition is off. This light reminds you to arm the theft-deterent system.

Arming the System

Use one of the two following items listed here to arm the system:

    • Press the lock button on the remote keyless entry transmitter.
    • Open the door. The SECURITY light should flash. Lock the door with the power door lock switch. The SECURITY light will stop flashing and stay on. Close the door. The security light should go off.

Now, if a door or the hatch/trunk lid is opened without the key or the remote keyless entry transmitter, the alarm will go off. Your horn will sound for two minutes, then it will go off to save battery power. And, your vehicle will not start.

The theft-deterrent system will not arm if you lock the driver's door with a key, the manual door lock, or if you use the power door lock after the doors are closed.

If your passenger stays in the vehicle when you leave with the keys, have the passenger lock the vehicle after the doors are closed. This way the alarm will not arm, and your passenger will not set it off.

Testing the Alarm

To test the system, do the following :

  1. Make sure the hatch/trunk lid is latched.
  2. Lower the window on the driver's door.
  3. Manually arm the system.
  4. Close the doors and wait 15 seconds.
  5. Reach through the open window and manually unlock the driver's door.
  6. Open the door. The alarm should sound.
  7. Turn off the alarm.

If the alarm is inoperative, check to see if the horn works. If not, check the horn fuse. See Fuses and Circuit Breakers . If the horn works, but the alarm does not go off, see your dealer.

Disarming the System

Always use your key or the remote keyless entry transmitter to unlock a door. Unlocking a door any other way will set off the alarm. If your alarm sounds, listed below are the ways you can disarm it.

    • Unlock the driver's door with your key.
    • Put the key in the ignition.
    • Press the unlock button on the remote keyless entry transmitter.
