When it is dark enough outside, your high-beam headlamps will change to low-beam headlamps at full brightness. The other lamps that turn on with your headlamps will also turn on. When it is bright enough outside, the regular lamps will turn off, and your high-beam headlamps change to the reduced brightness of DRL. To idle your vehicle with the DRL off, shift the transaxle into PARK (P). The DRL will stay off until you shift out of PARK (P). To turn off all exterior lighting at night when you are parked, turn off the exterior lamp control and slide the Twilight Sentinel® control all the way to the left. When released, the control will return to the Twilight Sentinel® minimum delay position and the lights will turn off. As with any vehicle, you should turn on the regular headlamp system when you need it. Twilight Sentinel® Twilight Sentinel® turns your headlamps on and off by sensing how dark it is outside. To operate this feature, slide the control to any position to vary the lamp time-out. You can set the delay time from only a few seconds to three minutes. If you move the control all the way to MAX, your lamps will remain on for three minutes after you turn off your engine. If you move the control almost all the way in the other direction, so it is just on, the lamps will go off quickly when you turn off your engine. Sliding the control to OFF, turns off the Twilight Sentinel® feature. 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. Light Sensor Your Twilight Sentinel® and DRL work with the light sensor on top of the instrument panel. Do not cover it up. If you do, it will sense "dark" and the headlamps will come on. 3-14
