This feature allows you to customize the interior lamps when entering and exiting the vehicle.

Programmable Modes

Mode 1: Both Features Off. The interior lamps will turn on or off at the same instant that a door is opened or closed.

Mode 2: Delayed Illumination Only. The interior lamps will stay on for about 25 seconds after all the doors and liftgate are closed, or until you lock the doors.

Mode 3: Exit Lighting Only. The interior lamps will come on whenever you remove the key from the ignition and stay on for about 25 seconds, or until you lock the doors.

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

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" earlier in this section.
  2. Turn the interior lamps on by turning the instrument panel brightness control all the way up.
  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 interior lamps off to change the current mode.
  5. Turn the interior lamps from on to 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.
