Wiper-Activated Headlamps This feature turns on the low-beam headlamps instrument panel cluster backlighting and taillamps when the Twilight SentinelR is in day mode and after the windshield wipers have been in use for approximately six seconds. To operate the wiper-activated headlamps, the Twilight Sentinel must be on. If the wiper-activated headlamps are on and the ignition switch is turned to RUN, the wiper-activated headlamps will continue. When you turn the key to OFF, the wiper-activated headlamps will immediately turn off. The wiper-activated headlamps will also turn off if you turn off the Twilight Sentinel or the windshield wipers. Lamps On Reminder If you leave the manual headlamp or parking lamp switch on, remove the key from the ignition and open the driver's door, you will hear a continuous warning chime. The chime will turn off when the lamps are turned off. Daytime Running Lamps Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. DRL can be helpful in many different driving conditions, but they can be especially helpful in the short periods after dawn and before sunset. Fully functional daytime running lights are required on all vehicles first sold in Canada. A light sensor on top of the instrument panel monitors the exterior light level for the operation of DRL and Twilight Sentinel, so be sure it isn't covered. The DRL system will make your high-beam headlamps turn on at reduced brightness in daylight when the following conditions are met: Parking Lamps Press the park button to turn on the parking lamps. Press it again to turn them off. (If the parking lamps were turned on with the park button, they must be turned off with that button). When the parking lamps are turned on during the day, the instrument panel cluster lights and backlighting to the buttons will turn on. At night, if the ignition key is turned to RUN, the brightness of this lighting can be adjusted using the instrument panel intensity/brightness control. The radio and climate control displays will also be on. D The ignition is on, D the headlamp switch is off and D the transaxle is not in PARK (P). 2-44
