Your vehicle may have a theft-deterrent alarm system.


Object Number: 806346  Size: A2

A light located on top of your 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 enter the vehicle without the optional remote keyless entry transmitter or the key or tries to turn the ignition on without using the correct key. The horn will sound and the headlamps and parking lamps will flash any time the alarm sounds.

To open the liftgate while armed, press the liftgate release button, located on the instrument panel switchbank, or press REAR on the remote keyless entry transmitter.

Arming with the Power Lock Switch

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 in no longer armed.
