Lighting 5-5 Fog Lamps Use the fog lamps for better vision in foggy or misty conditions. The fog lamp control is located on the turn signal/multifunction lever. # (Fog Lamps): Turn the fog lamp band on the lever up to # and release it, to turn the fog lamps on or off. The band will return to its original position. The parking lamps must be on for the fog lamps to work. If the high-beam headlamps are turned on, the fog lamps will also turn off. They will turn back on again when you change back to low-beam headlamps. Some localities have laws that require the headlamps to be on along with the fog lamps. Interior Lighting Instrument Panel Illumination Control The instrument panel brightness knob is located on the instrument panel to the left of the steering column. Reading Lamps The reading lamps are located on the overhead console. These lamps come on automatically when any door is opened. For manual operation, press the button next to each lamp to turn it on or off. If the reading lamps are left on, they automatically shut off 10 minutes after the ignition has been turned off. D (Instrument Panel Brightness): Turn the knob clockwise or counterclockwise to brighten or dim the lights. Turn the knob completely clockwise to turn on the interior lamps.
