Courtesy Lamps
The courtesy lamps turn on automatically when a door is opened.

Dome Lamps
The dome lamps are located in the overhead console and above the rear seat passenger area.
Interior lighting in the Buick Enclave is designed to make entry, exit, and passenger-area visibility easier during low-light conditions.
The dome lamps come on when a door is opened, unless the dome lamp override button has been pressed in.
The lamps can also be turned on and off by turning the instrument panel brightness control clockwise to the farthest position.

DOME OFF (Dome Lamp Override): Press the top of the button in to keep the dome lamps off when a door is opened.
An indicator light on the button comes on to show that the dome lamps are off. Press near the bottom of the button to allow the dome lamps to come on again when a door is opened.
