Twilight Sentinel@ 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. 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. You can change this delay time from only a few seconds to three minutes. The exterior lamps can be completely shut off while the vehicle is in PARK (P) by sliding the Twilight Sentinel@ lever all the way to OFF. To turn the exterior lamps back on, slide the lever toward MAX again, or shift out of PARK (P). Park Lamp Override Feature If the Twilight Sentinel@ lighting is active, it can be disabled by turning on the manual parking lamps. The lighting will be disabled until the ignition is moved from RUN or until the outside light level becomes daylight. The outside light level changing to daylight will cause the Twilight Sentinel@ feature to deactivate. The wiper-activated headlamps will override the twilight disable feature. To operate it, leave the exterior lamp button off. 3-14
