Center High-Mounted Stoplamp Interior Lamps Dome Lamps The dome lamps will come on when you open a door. You can also turn the dome lamps on by moving the thumbwheel, located next to the headlamp knob, all the way up to the second detent. In this position, the dome lamps will remain on whether a door is open or closed. Your vehicle's center high-mounted stoplamp is located above the rear doors at the center of the vehicle. If items are loaded on the roof of the vehicle, as in a luggage carrier, care should be taken not to block or damage the center high-mounted stoplamp unit. 2-42
