Dome Lamps
The dome lamps are located in the overhead console and above the rear seat passengers.
The dome lamps come on when a door is opened, unless the dome lamp override button is pressed in.
The lamps can also be turned on and off by turning the instrument panel brightness control clockwise to the farthest position.

Dome Lamp Override
The dome lamp override button is next to the exterior lamps control.
DOME OFF (Dome Lamp Override): Press the top of the button in and the dome lamps remain 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 so the dome lamps come on when a door is opened.
