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

Arming the System

To arm the system:

  1. Turn the ignition off.
  2. Press lock on the RKE transmitter.

The system will arm after either of the following occur:

    • 30 seconds after all the doors are closed.
    • 60 seconds with any door open.

Press the lock button on the RKE transmitter a second time, while all the doors are closed, to immediately arm the system. The system still arms in 60 seconds if a door is open. When the open door is closed, it also arms.

The security light turns on to indicate that arming has been initiated. Once the system is armed, the security light flashes once every three seconds.

If the security light flashes twice per second, a door is open.

Locking the vehicle with the manual lock knobs on the doors will not arm the system.

Disarming the System

Disarm the system by doing any one of the following:

    • Press the RKE transmitter unlock button.
    • Turn the ignition on.

Once the system is disarmed, the security light stops flashing.

How the System Alarm is Activated

If the system is armed, it can be activated by either:

    • Opening the driver's door or tailgate. This causes a 10 second pre-alarm chirp followed by a 30 second full alarm of horn and lights.
    • Opening any other door. This immediately causes a full alarm of horn and lights for 30 seconds.

When an alarm event has finished, the system re-arms itself automatically.

How to Turn Off the System Alarm

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

    • Press the lock button on the RKE transmitter. The system will then re-arm itself.
    • Press the unlock button on the RKE 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

The content theft security system alarm was previously activated if three chirps sound when you press the lock or unlock buttons on the RKE transmitter.
