yellowblue 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. 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: When it's bright enough outside, your headlamps will go off and your high-beam headlamps will come on. As with any vehicle, you should turn on the regular headlamp system when you need it. Delayed Headlamp Illumination Delayed headlamp illumination provides a period of exterior lighting as you leave your vehicle's area. The feature is activated when your vehicle's headlamps are on due to the automatic headlamp control feature described previously in this section, and when your vehicle's ignition is turned off. Your headlamps will then remain on until the headlamp switch is moved from OFF to the parking lamp position or until either a 30 second or 60 second lighting period has ended. If you turn off the ignition with the headlamp switch in the parking lamp or headlamp position, the delayed headlamp illumination cycle will not occur. To disable the delayed headlamp illumination feature or change the time of delay, see "Vehicle Customization Settings" in the Index. D D D D the ignition is on, the headlamp switch is off, the gearshift is not in PARK (P) and the parking brake is released. When the DRL are on, only your high-beam headlamps, at a reduced brightness, will be on. The headlamps, taillamps, sidemarker and other lamps won't be on. Your instrument panel won't be lit up either. When it's dark enough outside, your high-beam headlamps will turn off and your vehicle's headlamps and parking lamps will turn on. The other lamps that come on with your headlamps will also come on. 2-45
