Automatic Light Control (ALC) Your vehicle is equipped with an automatic light sensor on the top left corner of the instrument panel, so be sure it is not covered or the headlamps will be on continuously. When it is dark enough outside, your ALC will turn on your low-beam headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps and instrument panel lights. The parking brake must be released for ALC to work. This is indicated by the headlamp symbol on your instrument panel cluster. If you are driving through a parking garage, overcast weather, or a tunnel, the ALC may turn on your low-beam headlamps at a normal brightness along with the taillamps, sidemarker, parking lamps and the instrument panel lights. The radio lights will be dimmer, and the instrument panel cluster lights may dim. There will be a 10 to 15 second delay before the lights will turn on when starting the car at night. 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. The DRL system will make your headlamps come on at a reduced brightness when the following conditions are met: D The ignition is on with the engine running, D the exterior lamps switch is off and D the parking brake is released. When the DRL are on, only your headlamps will be on at a reduced brightness. The taillamps, sidemarker and other lamps won't be on. Your instrument panel won't be lit up either. When you turn the exterior lamp switch to the headlamp position, your DRL will go off and your headlamps will come on. The other lamps that come on with your headlamps will also come on. Lamps On Reminder If you turn the ignition to LOCK or ACC and leave the lamps on, you'll hear a tone when you open the driver's door. 2-43
