Your vehicle may have a theft-deterrent alarm system.


Object Number: 807013  Size: A2

A light located on top of the instrument panel (near the center of the vehicle, next to the windshield) will flash slowly to let you know that the system has been armed.

While armed, the doors will not unlock with the power door lock switch.

Once armed, the alarm will go off if someone tries to open one of the doors on the vehicle without the remote keyless entry transmitter or the key, or tries to turn the ignition without using the correct key. The horn will sound and the headlamps and parking lamps will flash any time the alarm sounds.

If you would like to change the way the headlamps, parking lamps and horn operate with the content theft-deterrent system, and your vehicle is equipped with the Driver Information Center (DIC), see DIC Vehicle Personalization .

When the content theft-deterrent system is armed, the liftgate/tailgate may be opened by using one of the following methods:

    • From the outside, insert the key into the lock and turn it clockwise, or
    • press REAR on the remote keyless entry transmitter.

When the content theft-deterrent system is armed, pressing the liftgate release button, located on the instrument panel switchbank, will cause the alarm to sound.

Arming with the Power Lock Switch

Your alarm system will arm when you use either power door lock switch to lock the doors while any door or the liftgate/tailgate is open and the key is removed from the ignition. The security light will start flashing to let you know the system is armed.

Arming with the Remote Keyless Entry Transmitter

Your alarm system will arm when you press LOCK on your remote keyless entry transmitter to lock the doors. The security light will start flashing to let you know the system is armed.

Disarming with Your Key

Your alarm system will disarm when you use your key to unlock the front doors. The security light will stop flashing to let you know the system is no longer armed.

Disarming with the Remote Keyless Entry Transmitter

Your alarm system will disarm when you press UNLOCK on your remote keyless entry transmitter to unlock the doors. The security light will stop flashing to let you know the system is no longer armed.
