When the DRL are on, only your high-beam headlamps will be on. The parking lamps, taillamps, sidemarker and other lamps won't be on. When it is dark enough outside, your low-beam headlamps will come on. The other lamps that turn on with your headlamps will also turn on. When it is bright enough outside, the regular lamps will go off, and your high-beam headlamps change to the reduced brightness of DRL. To turn off all exterior lighting at night when you are parked, turn off the headlamps and move the Twilight Sentinel lever all the way toward OFF. The exterior lamps will turn back on automatically when you move the transaxle out of PARK (P). As with any vehicle, you should turn on the regular headlamp system when you need it. Twilight SentinelR Twilight Sentinel turns your headlamps on and off by sensing how dark it is outside. The lever for this feature is located to the left of the steering column. Cornering Lamps (If Equipped) 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. To operate it, leave the exterior lamp button off. If you slide the lever all the way to MAX, your headlamps will remain on for about three minutes after you turn off your engine. As you slide the lever toward OFF, the headlamps will turn off more quickly when you move your key from RUN. You can change this delay time from only a few seconds to three minutes. 2-45
