Fog Lamps Your vehicle may have fog lamps. If it does, the fog lamps switch is located in the instrument panel switchbank. Press the fog lamp symbol on the switch to turn on the lamps. At night, when the light sensor automatically turns on your headlamps, the fog lamps can be turned on while the exterior lamps control is in any position. Your fog lamps will go off when you switch to high beams. Using your high beams in fog is not recommended. Interior Lamps Instrument Panel Brightness The thumbwheel for this feature is located below the exterior lamps control. Turn the thumbwheel to the right to brighten the lights, or to the left to dim them. Interior Lamps Control The indicator light will be lit while the fog lamps are on. Press the top part of the switch to turn them off. When your DRL are on, the exterior lamps control must first be turned from the off position before the fog lamps can be turned on. Your parking lamps or headlamps must be on for your fog lamps to turn on. Turn the thumbwheel all the way to the right to turn on the interior lamps, if the interior lamps override switch is off. Turn the thumbwheel to the left to turn the lamps off. 3-18
