Vehicle Security

This vehicle has theft-deterrent features; however, they do not make the vehicle impossible to steal.

Vehicle Alarm System

This vehicle has an anti-theft alarm system.

Arming the Alarm System

1. Close the liftgate and the hood. Turn off

the vehicle.

2. Lock the vehicle in one of three ways: . Use the remote key. . Use the Keyless Access system. . With a door open, press the inside Q.

3. After 30 seconds the alarm system will

arm. Pressing Q on the remote key a second time will bypass the 30-second delay and immediately arm the alarm system.

The vehicle alarm system will not arm if the doors are locked with the key. If the driver door is opened without first unlocking with the remote key, the horn will chirp and the lights will flash to indicate pre-alarm. If the vehicle is not started, or the door is not unlocked by pressing K on the remote key during the 10-second pre-alarm, the alarm will be activated. The alarm will also be activated if a passenger door, the liftgate, or the hood is opened without first disarming the system. When the alarm is activated, the turn signals flash and the horn sounds for about 30 seconds. The alarm system will then re-arm to monitor for the next unauthorized event.

Disarming the Alarm System

To disarm the alarm system or turn off the alarm if it has been activated: . Press K on the remote key.

. Unlock the vehicle using the Keyless Access system.

. Start the vehicle. To avoid setting off the alarm by accident: . Lock the vehicle after all occupants have

left the vehicle and all doors are closed. . Always unlock a door with the remote

key or use the Keyless Access system. Unlocking the driver door with the key will not disarm the system or turn off the alarm.

How to Detect a Tamper Condition

If K is pressed and the horn chirps and the lights flash three times, the alarm was activated while the alarm system was armed. If the alarm system has been activated, a message will appear on the Driver Information Center (DIC).

Immobilizer

See Radio Frequency Statement 0 337.

Immobilizer Operation

This vehicle has a passive theft-deterrent system.

The system does not have to be manually armed or disarmed. The vehicle is automatically immobilized when the remote key leaves the vehicle. The immobilization system is disarmed when the ignition is turned on or in ACC/ ACCESSORY and a valid remote key is in the vehicle.

The security light, in the instrument cluster, comes on if there is a problem with arming or disarming the theft-deterrent system. The system has one or more remote keys matched to an immobilizer control unit in the vehicle. Only a correctly matched remote key will start the vehicle. If the remote key is ever damaged, you may not be able to start the vehicle. When trying to start the vehicle, the security light may come on briefly when the ignition is turned on.

If the engine does not start and the security light stays on, there is a problem with the system. Turn the ignition off and try again. If the ignition will not change from off to on or ACC/ACCESSORY, and the remote key appears to be undamaged, try another remote key. Or, you may try placing the remote key in the cupholder in the center console. See Remote Key Operation 0 7. If the vehicle will not start with the other remote key, or with the remote key in the cupholder, the vehicle needs service. If the vehicle does start, the first remote key may be faulty. See your dealer who can service the theft-deterrent system and have a new remote key programmed to the vehicle. It is possible for the immobilizer system to learn new or replacement remote keys. Up to eight remote keys can be programmed to the vehicle. To program additional remote keys, see “Programming remote keys to the Vehicle” under Remote Key Operation 0 7. Do not leave the remote key or device that disarms or deactivates the theft-deterrent system in the vehicle.
