With the last door closed locking and lockout prevention features, your vehicle will do the following:

    • If you leave your key in the ignition and leave the driver's door open, you won't be able to use the power door lock switches to lock the doors.
    • The doors will not lock when you press LOCK on the driver's door arm rest or the lock button on the remote keyless entry transmitter (if equipped) while any door is open. Instead, you will hear three chimes which let you know that the last door closed locking feature is in operation. Five seconds after all the doors are closed, all the doors will automatically lock.

Programmable Modes

Mode 1: Both Features Off - Doors will always lock immediately when you press LOCK on the driver's door armrest or the remote keyless entry transmitter, if equipped.

Mode 2: Lockout Prevention Only - If you leave your key in the ignition with the driver's door open, you will not be able to lock the doors using your power locks .

Mode 3: Last Door Closed Locking Only - If the power door lock switch or remote keyless entry transmitter, if equipped, is used to lock the vehicle while any door is open and the key is out of the ignition, you will hear three chimes. The doors will not lock. Five seconds after the last door is closed, all doors will lock.

Mode 4: Both Features On - This combines Modes 2 and 3.

Before your vehicle was shipped from the factory, it was programmed to Mode 4. The mode to which your vehicle was programmed may have changed since it left the factory. To determine the mode to which your vehicle is programmed or to program your vehicle to a different mode, do the following:

  1. Follow the instructions for Entering Programming Mode .
  2. Press UNLOCK on the driver's door armrest or the unlock button on the remote keyless entry transmitter.
  3. Count the number of chimes you hear. The number of chimes tells you which mode your vehicle is set for. 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. Press UNLOCK again to change the current mode.
  5. Repeat Step 4 until you hear the number of chimes that matches the mode 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. See Exiting Programming Mode .
