Headlamps On Reminder A tone will sound when your headlamps are turned on and your ignition is in OFF, LOCK or ACCESSORY. If you need to use your headlamps when the ignition switch is in OFF, LOCK or ACCESSORY, the tone can be turned off by moving the instrument panel brightness thumbwheel next to the exterior lamp control all the way down. The DRL system will make your headlamps come on at a reduced brightness when the following conditions are met: D The ignition is on, D The exterior lamp control is off, and D The parking brake is released. When the DRL are on, only your 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 begins to get dark, your DRL indicator light is a reminder to turn the headlamps on. The other lamps that come on with your headlamps will also come on. When you turn off the headlamps, the regular lamps will go off, and your headlamps will change to the reduced brightness of DRL. To idle your vehicle with the engine on and the DRL off, set the parking brake. The DRL will stay off until you release the parking brake. As with any vehicle, you should turn on the regular headlamp system when you need it. 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 lamps are required on all vehicles first sold in Canada. 2-42
