Before your vehicle was shipped from the factory, it was programmed to Mode 4. The mode to which your vehicle was programmed may have been 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. Turn the interior lamps thumbwheel all the way to the right and then back slightly to the left.
  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. Turn the interior lamps thumbwheel all the way to the right and then back slightly to the left again to change the current mode.
  5. Repeat Step 4 until you hear the number of chimes that matches the number of 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 .
