Twilight Sentinel® This feature 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® you will see the following happen: You can idle the vehicle with the lamps off, even when it is dark outside. After starting the vehicle, turn the exterior lamp control band to off, then release it. The lamps will remain off until you turn the control band to off again. Twilight Sentinel® also provides exterior illumination as you leave the vehicle. If Twilight Sentinel® has turned on the lamps when you turn off the ignition, the lamps will remain on until: • 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. • The exterior lamp switch is moved from OFF to the parking lamp position, or • 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 will 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. See Instrument Panel Brightness on page 3-30 for more information. • the delay time selected has elapsed. See Driver Information Center (DIC) on page 3-57 to select the delay time. You can also select no delay time. If the ignition is turned off with the exterior lamp switch in the parking lamp or headlamp position, the Twilight Sentinel® delay will not occur. The lamps will turn off as soon as the switch is turned off. The regular headlamp system should be turned on when needed. 3-29
