D The ignition is on, D the headlamp control is off, and D the parking brake is released. When the DRL are on, only your front parking and turn signal lamps will be on. Your instrument panel won't be lit up. When it's dark enough outside, the exterior lamps will come on automatically. When it's bright enough outside, the exterior lamps will turn off and the DRL will turn on. Of course, you may still turn on the headlamps any time you need to. To idle your vehicle with the DRL, set the parking brake while the ignition is in OFF or LOCK. Then start the 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. Lamps on Reminder If the driver's door is opened and you turn the ignition to OFF or LOCK while leaving the lamps on, you will hear a warning chime. 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. 2-65
