yellowblue 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. A light sensor on top of the instrument panel monitors the exterior light level for the operation of DRL and Twilight SentinelR, so be sure it isn't covered. The DRL system will make your low-beam headlamps come on at a reduced brightness when: When it's dark enough outside, your low-beam headlamps will change to full brightness. The other lamps that come on with your headlamps will also come on. When it's bright enough outside, the regular lamps will go off, and your low-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). At night, you can turn off all exterior lamps when you are in PARK (P) by moving the twilight sentinel control all the way to OFF. If it was on OFF, move the control to the right to turn it on, then back to OFF. The lamps will come back on when you put the transaxle in gear. Twilight sentinel will keep your headlamps on for up to three minutes, to light your way when you leave your vehicle. See "Twilight Sentinel" later in this section to learn how to operate this feature. As with any vehicle, you should turn on the regular headlamp system when you need it. D The ignition is on, D the headlamp switch is off and D the transaxle is not in PARK (P). When the DRL are on, only your low-beam headlamps will be on. The taillamps, sidemarker and other lamps won't be on. Your instrument panel won't be lighted either. 2-41
