Delayed Headlamps The delayed headlamps feature provides a period of exterior lighting as you leave the area around your vehicle. The feature is activated when the headlamps are on due to the automatic headlamps control feature described previously in this section, and when the ignition is turned off. Your headlamps will then remain on until the exterior lamps control is moved to the parking lamps position or until the pre-selected delayed headlamp lighting period has ended. If you turn off the ignition with the headlamps switch in the parking lamps or headlamps position, the delayed headlamps cycle will not occur. To disable the delayed headlamps feature or change the time of delay, see DIC Vehicle Customization on page 206. Daytime Running Lamps (DRL)/ Automatic Headlamp System 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. A light sensor on top of the instrument panel makes the DRL work, so be sure it is not covered. The DRL system's automatic headlamp control will make the low-beam headlamps come on at a reduced brightness when the following conditions are met: • The ignition is in RUN. • The exterior lamps control is in AUTO. • The engine is running. When the DRL are on, only the low-beam headlamps, at a reduced level of brightness, will be on. The headlamps, taillamps, sidemarker, and other lamps will not be on. The instrument panel and cluster will also not be lit. 160
