Your vehicle has a theft-deterrent alarm system.


Object Number: 810448  Size: B3

A red light located on top of the instrument panel, toward the center of the vehicle and near the windshield, will flash slowly when the system is armed.

While armed, the doors will not unlock with the power door lock switch. The alarm will sound if someone tampers with the trunk lock, enters the vehicle without using the remote keyless entry transmitter or key to unlock the doors, or turns the ignition on. The horn will sound and the headlamps will flash for up to two minutes. The system will also cut off the fuel supply, preventing the vehicle from being driven.

Arming with the Power Lock Switch

Your alarm system can be programmed to arm when you use either power lock switch to lock the doors while any door is open and the key is removed from the ignition. If you would like to arm the system with the power lock switch, see Vehicle Personalization . When programmed, the red light will flash quickly to let you know that the system is ready to arm with the power lock switches. When you press the rear of a power door lock switch, the red light will stop flashing and stay on to let you know that the system is arming. After all the doors are closed and locked, the red light will begin flashing at a very slow rate to let you know the system is armed.

Arming with the Remote Keyless Entry Transmitter

The alarm system will arm when you use the remote keyless entry transmitter to lock the doors after the key is removed from the ignition. The red light will turn on to let you know the system is arming. After all doors are closed and locked, the red light will begin flashing at a very slow rate to let you know the system is armed.

Arming Confirmation

If the remote unlock confirmation is on, the headlamps will flash briefly to let you know when the alarm system has armed. See Vehicle Personalization for programming information.

Disarming with the Remote Keyless Entry Transmitter

The alarm system will disarm when you use your remote keyless entry transmitter to unlock the doors. The red light will go off to let you know the system is disarmed.

Disarming with Your Key

The alarm system will disarm when you use the key to unlock the doors. The red light will stop flashing when the system is disarmed. If you would like the key to disarm the alarm system, see Vehicle Personalization .
