6-6 Lighting Fog Lamps The fog lamp button is located in the exterior lamps control. Off-Road Lamps For vehicles with off-road lamps, they provide auxiliary lighting when the vehicle is used off road. These lamps are not intended to be used in place of existing vehicle lighting. They are not to be used on any public street or highway and are to be covered when not in use. Check your state and local laws before installing or using any auxiliary lighting. In some states it may be necessary to remove the roof lamps when operating the vehicle on the highway. # (Fog Lamps): The headlamps or parking lamps must be on for the fog lamps to work. Press # to turn the fog lamps on or off. An indicator light turns on when the fog lamps are on. Never use the fog lamps in the dark without turning on the headlamps. When the high-beam headlamps are turned on, the fog lamps turn off automatically. When the high-beam headlamps are turned off, the fog lamps come on again. Some localities have laws that require the headlamps to be on along with the fog lamps. The off-road lamps button is located on the instrument panel below the climate controls. Remove the covers from the lamps and press the button to turn them on or off. An indicator light turns on when the lamps are on.
