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 lights and dome lamps remain on after the door is closed for a set amount of time, then automatically turn off.

For vehicles with keyless access, the exterior lights and dome lamps automatically turn on when a door is opened after the ignition is turned off. See Ignition Positions (Key Access) or Ignition Positions (Keyless Access).

The exterior lights turn off immediately by turning the exterior lamps control off.

This feature can be changed. See Vehicle Personalization.
