To arm or disarm the content theft-deterrent system, the system must be turned on by using Modes 1, 2, or 4 listed previously.

This feature allows you to customize the arming and disarming of the content-theft deterrent system.

Programmable Modes

Mode 1: Power Door Lock Switch Arming Off

    • The system will arm when you lock the doors with your key or remote keyless entry transmitter. The key must be removed from the ignition when you lock the doors or the content theft-deterrent system will not arm.
    • The system will disarm when you unlock the doors with your key or remote keyless entry transmitter.
Mode 2: Remote Keyless Entry Transmitter Arm/Disarm Only

    • The system will arm when you lock the doors with your remote keyless entry transmitter. The key must be removed from the ignition when you lock the doors or the content theft-deterrent system will not arm.
    • The system will disarm when you unlock the doors with your remote keyless entry transmitter.

While this mode provides increased security, it can be a problem if your remote keyless entry transmitter is damaged, lost, or if it fails to operate for any reason while the content theft-deterrent system is armed. The content theft-deterrent system must be disarmed for the engine to run while in Mode 2; your key can no longer disarm the system.

If your vehicle is equipped with the OnStar® system, OnStar® will not be able to remotely unlock your vehicle if it has been programmed to Mode 2.

Mode 3: Standard Arming and Disarming

    • The system will arm when you lock the doors using either power door lock switch while any door or the liftgate is open and the key is removed from the ignition.
    • The system will arm when you lock the doors with your key or remote keyless entry transmitter and the key is removed from the ignition.
    • The system will disarm when you unlock the doors with your key or remote keyless entry transmitter.

Your vehicle was originally programmed to Mode 1. 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. Insert your spare key fully into any door key cylinder and turn it to the unlock position.
  3. This step is necessary to prevent accidental programming of this feature to Mode 2. Do not program this feature to Mode 2 without first reading Mode 2 entirely. The door key cylinder must remain in the unlock position during Steps 2 through 4.

  4. Press the button with the horn symbol on the remote keyless entry transmitter.
  5. 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.
  6. Press the panic button to change the current mode.
  7. Press the panic button until you hear the number of chimes corresponding to the mode selection you want.
  8. Remove your key from the door key cylinder.

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