Push in the headlight switch to turn your headlights off. 2. Rotate the Twilight Sentinel switch counterclockwise from OFF. The Twilight Sentinel Does Two Things: First, depending on how dark it becomes outside, the Twilight Sentinel turns your headlights on automatically, when they're needed. Avoid covering the sensor located near the windshield,by the defroster outlet-otherwise your headlights will stay on. Also, it's possible that your headlights might go out if you drove from a dark area into a bright area, such as a lighted parking lot. If this happens, turn on your headlights with the regular headlight switch. l m m m 84
