After you exit the vehicle and all of the doors have been closed, the lamps will stay on for an additional four seconds before fading off. These lampswill also go on when you press the LOCK or UNLOCK button on the optional remote keyless entry transmitter. You can brighten or dim the instrument panel lights by turning the dial left or right. Turn the dial up all the way to the right to turn on the interior courtesy lamps.
