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. Daytime Running Lamps (DRL) 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 lamps 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: Lamps On Reminder If you leave the exterior lamp buttons for the headlamps or parking lamps 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. D The ignition is on, D the exterior lamp button for the headlamps is off and D the transaxle is not in PARK (P). 2-44
