With this system, the security light will flash when the door is open and locked with the power door lock switch.

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

Arming the System

To arm the system:

    • Press [block ] on the keyless access transmitter.
    • Open the door. Lock the door with the power door lock switch. The security light should flash. Remove the keyless access transmitter from the interior of the vehicle and close the door. The security light will stop flashing and stay on. After 30 seconds, the light should turn off.
        The vehicle can be programmed to automatically lock the doors and arm the system when you exit the vehicle. See DIC Vehicle Personalization .

Now, if a door or the trunk lid is opened without the keyless access transmitter, the alarm will go off. The horn will sound for two minutes, then it will go off to save battery power. And, the vehicle will not start without a keyless transmitter present.

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

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

Testing the Alarm

To test the system:

  1. Close the trunk lid.
  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. Turn off the alarm by pressing on the transmitter.

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 doesn't go off, see your dealer/retailer.

Disarming the System

Always use the keyless access transmitter to unlock a door either by pressing on the transmitter or by squeezing the door handle sensor while you have the transmitter with you. Unlocking a door any other way will set off the alarm. If the alarm sounds, press 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.
