Daytime Running Lamps / Automatic Headlamp Control 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 makes the DRL work, so be sure it isn't covered. The DRL system will make your high-beam headlamps come on at a reduced brightness when the following conditions are met: When it's dark enough outside, your DRL will turn off and your low-beam headlamps will illuminate. The other lamps that come on with your headlamps will also come on. When it's bright enough outside, the low-beam headlamps will go out, and DRL illuminates your high-beam headlamps at reduced intensity. To idle your vehicle with the DRL off, set the parking brake while the ignition is in OFF or LOCK. Then start your vehicle. 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. D The ignition is on, D the headlamp switch is off and D the parking brake is released. When the DRL are on, only your reduced intensity high-beam headlamps will be on. The taillamps, sidemarker and other lamps won't be on. Your instrument panel won't be lit up either. Interior Lamps Instrument Panel Brightness Control This thumbwheel is located next to the exterior lamps control and is shown as (A) in the previous photo. You can brighten or dim the instrument panel lights by moving the thumbwheel up or down. If you turn the thumbwheel all the way up, your courtesy or interior lamps will come on. 2-33
