This feature allows you to turn the content theft deterrent on and off.

Programmable Modes

Mode 1, Mode 2 and Mode 4: Feature On. If anyone opens a door or the liftgate while your content theft-deterrent system is armed, an alarm will sound and your parking lamps will flash for up to two minutes.

Mode 3: Feature Off. Your content theft-deterrent system is always disarmed.

Your vehicle was originally programmed to Mode 4. The mode may have been changed since then. To determine the current mode, or to change the mode, do the following:

  1. Follow the instructions for Entering Programming Mode .
  2. Turn the parking lamps on, then off.
  3. Count the number of chimes you hear. The number of chimes indicates the vehicle's current programmed mode. If you do not wish to change the current mode, you can either exit the programming mode by following the instructions later in this section or program the next feature available on your vehicle.
  4. Turn the parking lamps on, then off to change the current mode.
  5. Turn the parking lamps on, then off until you hear the number of chimes corresponding to the mode selection you want.

The mode you selected is now set. You can either exit the programming mode by following the instructions later in this section or program the next feature available on your vehicle.
