Daytime Running Lamps / Automatic Light Control Daytime Running Lamps (DRL) can makeit 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 inthe short periods after dawn and before sunset. A light sensor below the defroster grille makes the DRL and Automatic Light Control (ALC) work, so be sure it isn't covered. The DRL systemwill make your low-beam headlamps come on a atreduced brightness when: 0 0 When theDRL 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 lit up either. When it's dark enough outside, the ALC system will turn your headlamps on to full brightness. The other lamps that come on with your headlamps will also come on. When it's bright enough outside, the ALC system will turn off your regular lamps, and your low-beam headlamps change to the reduced brightness of DRL. To idle your vehicle with the DIU off, set the park brake while the ignition is off. Then start the vehicle. The DRL will stay off until you release the park brake. As with any vehicle, you should turn on the regular headlamp system when you need it.
