Your vehicle may have a content theft-deterrent alarm system.

United States shown, Canada similar


Object Number: 1865572  Size: A1

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

To arm the theft-deterrent system, press the lock button on the RKE transmitter when all doors and the hood (vehicles started with the remote start feature only) are closed. The security light will come on solid for approximately 30 seconds and then flashes slowly. If the lock button on the RKE transmitter is pressed a second time, the theft-deterrent system will activate immediately, bypassing the 30 second delay. The content theft deterrent alarm is not armed until the security light flashes slowly.

If any door, liftgate or the hood (vehicles started with the remote start feature only) are opened without using the key or pressing the unlock button on the RKE transmitter, the exterior lamps flash and the horn will sound for about 30 seconds. If the lock or unlock button on the RKE transmitter is not pressed, the alarm sounds and periodically repeats. If the system does not operate as described above, see your dealer/retailer for service.

The theft-deterrent system also activates if you lock the doors with a key.

To avoid setting off the alarm by accident, always unlock a door with the RKE transmitter or a key. Unlocking a door any other way will set off the alarm if the system has been armed.

If you set off the alarm by accident, turn off the alarm by pressing lock or unlock on the RKE transmitter or by placing the key in the ignition and turning it to START.

Testing the Alarm

To test the alarm:

  1. From inside the vehicle, lower the driver's window and open the driver's door.
  2. Get out of the vehicle, close the door and activate the system by locking the doors with the RKE transmitter.
  3. Wait for the security light to flash slowly.
  4. Then reach in through the window, unlock the door with the manual door lock and open the door. This should set off the alarm.

If the alarm does not sound when it should, but the vehicle's headlamps flash, check to see if the horn works. The horn fuse may be blown. To replace the fuse, see Fuses and Circuit Breakers .

If the alarm does not sound or the vehicle's headlamps do not flash, see your dealer/retailer for service.
