The DRL system will make your high-beam headlamps come on at a reduced brightness when the following conditions are met: Delayed Headlamp Illumination Delayed headlamp illumination provides a period of exterior lighting as you leave the area. The feature is activated when the headlamps are on due to the automatic headlamp control feature described previously in this section, and when the ignition is turned off. Your headlamps will then remain on until the headlamp knob 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 knob 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 The ignition is on, D the headlamp switch is off and D the gearshift is not in PARK (P). When the DRL are on, only your high-beam headlamps, at a reduced level of brightness, will be on. The headlamps, taillamps, sidemarker and other lamps won't be on. Your instrument panel and cluster won't be lit up either. When it's dark enough outside, your high-beam headlamps will turn off and the headlamps and parking lamps will turn on. The other lamps that come on with your headlamps will also come on. When it's bright enough outside, your headlamps will go off and your DRL will come on. As with any vehicle, you should turn on the regular headlamp system when you need it. 2-52
