Courtesy Lamps
The courtesy lamps automatically come on when a door is opened.
The lamps can also be turned on manually by fully turning the instrument panel brightness control clockwise.
The reading lamps, located on the headliner above the rearview mirror, can be turned on or off independently of the automatic courtesy lamps, when the doors are closed.
