Instrument Panel 3-13 Delayed Headlamps Delayed headlamps provide a period of exterior lighting as you leave the area around your vehicle. This feature is activated when the headlamps are on due to the automatic headlamps control feature, and when the ignition is turned off. The headlamps 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 the ignition is turned off 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 3-59. 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. 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 do not cover the sensor. The DRL system's automatic control makes the DRL lights come on when the following conditions are met: When the DRL are on, only the DRL lights will be on. The headlamps, taillamps, sidemarker, and other lamps will not be on. The instrument panel and cluster will also not be lit. When it is dark enough outside, the DRL lights will turn off and the headlamps and parking lamps will turn on. The other lamps that come on with the headlamps will also come on. When it is bright enough outside, the headlamps will go off and the DRL will come on. The regular headlamp system should be turned on when it is needed. • The ignition is in the ON/RUN position. • The exterior lamps control is in AUTO. • The engine is running.
