Fog Lamps Use the fog lamps for better vision in foggy or misty conditions. The fog lamps button is located on the exterior lamps control to the left of the steering column. Exterior Lighting Battery Saver If the exterior lamp button has been left on, the exterior lamps will turn off about 10 minutes after the ignition is turned to LOCK/OFF and a door has been opened. This protects against draining the battery if the headlamps or parking lamps are accidentally left on. If you need to leave the lamps on for more than 10 minutes, use the exterior lamp control to turn the lamps back on after the ignition is turned to LOCK/OFF and any door is opened. # (Fog Lamps): Press the exterior lamps button to turn the fog lamps on or off. A light comes on in the instrument panel cluster when the fog lamps are in use. The ignition must be on for the fog lamps to work. When the headlamps are changed to high-beam, the fog lamps will turn off. The fog lamps come back on again when the high-beam headlamps are turned off. Some localities have laws that require the headlamps to be on along with the fog lamps. Instrument Panel Brightness D (Instrument Panel Brightness): This feature controls the brightness of the instrument panel and footwell lights, if equipped. The button for this control is located below the exterior lamps control. Push the button in and release to extend the button. Turn the button clockwise or counterclockwise to brighten or dim the lights. Cornering Lamps The cornering lamps come on when the headlamps or parking lamps are on and you signal a turn with the multifunction lever. They provide more light for cornering. 3-34
