Fog Lamps Your vehicle has fog lamps. You can use them for better vision in foggy or misty conditions. Your parking lamps and/or low-beam headlamps must be on for your fog lamps to work. The fog lamp button is located in the exterior lamps control. Instrument Panel Brightness D (Instrument Panel Brightness): This feature controls the brightness of the instrument panel lights. The thumbwheel for this feature is located next to the exterior lamp control. Turn the thumbwheel up or down to brighten or dim the instrument panel lights and the radio display. The instrument panel lights, cluster, and radio display do not dim to complete darkness. Turn the thumbwheel all the way up to turn the dome lamps on. Dome Lamp Press the button to turn the fog lamps on while the headlamps or parking lamps are on. Press the button again to turn them off. An indicator light will glow in the button when the fog lamps are on. Remember, fog lamps alone will not give off as much light as your headlamps. Never use your fog lamps in the dark without turning on the headlamps. The fog lamps will go off whenever your high-beam headlamps come on. When the high beams go off, the fog lamps will come on again. Some localities have laws that require the headlamps to be on along with the fog lamps. The dome and footwell lamps come on when any door is opened. The dome lamps are located in the cargo and front area of the vehicle. The dome and footwell lamps can be turned on by turning the thumbwheel, located next to the exterior lamps control, all the way up. In this position, the lamps remain on whether a door is opened or closed. 3-19
