Fog Lamps Use fog lamps for better vision in foggy or misty conditions. The fog lamps control is located on the multifunction lever next to the exterior lamp control. Twilight Sentinel® Twilight Sentinel® can turn the lamps on and off for you. A light sensor on top of the instrument panel makes the Twilight Sentinel® work, so be sure it is not covered. With Twilight Sentinel®, the following will happen: # (Fog Lamps): Turning the band to this position will turn the fog lamps on. When you turn the fog lamps on, the fog lamp light will appear on the instrument panel cluster to indicate that the fog lamps and the parking lamps are on. If you turn the high-beam headlamps on, the fog lamps will turn off. They will turn on again when you switch to low-beam headlamps. The ignition must be on for the fog lamps to operate. Some localities have laws that require the headlamps to be on along with the fog lamps. • When it is dark enough outside, the front turn signal lamps (DRL) will go off, and the headlamps and parking lamps will come on. The other lamps that come on with headlamps will also come on. • When it is bright enough outside, the headlamps will go off, and the front turn signal lamps (DRL) will come on, as long as the exterior lamp switch is in the AUTO position. If the vehicle is started in a dark garage, the automatic headlamp system come on immediately. Once the vehicle leaves the garage, it takes about one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, the instrument panel cluster may not be as bright as usual. Make sure the instrument panel brightness control is in full bright position.
