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


Object Number: 822610  Size: A1

The security light, located on the instrument panel cluster, will turn on to indicate that arming has been initiated.

Once the system is armed, the security light will flash once every three seconds.

If the security light is flashing twice per second, this means that a door is open.

Arming the System

While the ignition is off, press the remote keyless entry transmitter lock button, to arm the system.

The system will arm after either of these things occur:

    • Thirty seconds after all the doors are closed.
    • Sixty seconds with any door open.

If you press the lock button on the transmitter a second time while all the doors are closed, the system will arm immediately. The system arms in 60 seconds if a door is open, or after the open door is closed.

If you do not want to arm the system, lock the car with the manual door lock knobs.

Disarming the System

You can disarm the system by doing any one of the following:

    • Press the unlock button on the remote keyless entry transmitter.
    • Turn the ignition on.

If the system is armed and the trunk is opened using the trunk release button on the transmitter, the system will temporarily disarm itself and re-arm when the trunk has been closed. This allows you to exit the vehicle, lock the doors using the transmitter, or open the trunk using the transmitter without having to disarm and re-arm the system.

Once the system is disarmed, the security light will stop flashing.

How the System Alarm is Activated

If the system is armed, it can be activated by opening the driver or passenger door or the trunk. This immediately causes a full alarm of the horn sounding and lights flashing for 30 seconds.

After the 30 second alarm ends, the system will re-arm itself.

How to Turn Off the System Alarm

To turn off the system alarm, do one of the following:

    • Press the lock button on the remote keyless entry transmitter. The system will then re-arm itself.
    • Press the unlock button on the remote keyless entry transmitter. This will also disarm the system.
    • Insert the key in the ignition and turn it on. This will also disarm the system.

How to Detect a Tamper Condition

If you hear three chirps when you press the unlock, lock, or trunk release buttons on the remote keyless transmitter, it means that the content theft security system alarm was activated previously.
