Dome Lamps
The dome lamps are located in the overhead console.
They come on when any door is opened and turn off after all the doors are closed.
Turn the instrument panel brightness knob located below the dome lamp override button, clockwise to the farthest position to manually turn on the dome lamps.
The dome lamps remain on until the knob is turned counterclockwise.
