Exterior Lamps Headlamps See "Turn Signal/Multifunction Lever" in the Index. When the DRL system is on, the taillamps, sidemarker lamps, parking lamps and instrument panel lights will not be illuminated unless you have turned the headlamp control to the parking lamp or headlamp position. The DRL system will remain off any time your vehicle is in PARK (P) or the parking brake is engaged and the vehicle speed is less than 8 mph (13 km/h). 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 lights are required on all vehicles first sold in Canada. The DRL system will make your low-beam headlamps come on at a reduced brightness when the following conditions are met: Automatic Light Control (ALC) When it is dark enough outside, your Automatic Light Control (ALC) will turn on your headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps and the instrument panel lights. The radio lights will also be dim. Your vehicle is equipped with a light sensor on the top of the instrument panel under the defroster grill, so be sure it is not covered which will cause the ALC system to be on whenever the ignition is on. The ALC system may also be on when driving through a parking garage, heavy overcast weather or a tunnel. This is normal. D The ignition is on, D the headlamp switch is to AUTO or you have turned on your parking lamps, D the light sensor detects daytime light, D the parking brake is released, and D the shift lever is not in PARK (P). 2-39
