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 SentinelR, so be sure it isn't covered. The DRL system will make your high-beam headlamps come on at reduced brightness in daylight when the following conditions are met: When it's dark enough outside, your high-beam headlamps will change to low-beam headlamps at full brightness. The other lamps that turn on with your headlamps will also turn on. When it's bright enough outside, the regular lamps will turn off, and your high-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). To turn off all exterior lighting at night when you are parked, turn off the headlamps and slide the Twilight Sentinel control all the way to the left When released, the control will return to the Twilight Sentinel minimum delay position and the lights will turn off. 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 DRL are on, only your high-beam headlamps will be on. The parking lamps, taillamps, sidemarker and other lamps won't be on. Your instrument panel won't be lit up either. Cornering Lamps The cornering lamps are designed to come on when you signal a turn. This will provide more light for cornering at night. 2-44
