Exit Lighting
The headlamps, taillamps, parking lamps, back-up lamps, and license plate lamps come on at night, or in areas with limited lighting, when the key is removed from the ignition.
The dome lamps also come on when the key is removed from the ignition. The exterior lamps and dome lamps remain on after the door is closed for a set amount of time, then automatically turn off.
The exterior lamps turn off immediately by turning the exterior lamps control off.
The exit lighting feature can be changed. See Vehicle Personalization .
