Cleaning the Intellibeam Light Sensor The light sensor is located on the inside of the vehicle in front of the interior rearview mirror. Headlamps on Reminder A warning chime will sound if the exterior lamp control is left on in either the headlamp or parking lamp position and the driver's door is opened with the ignition off. See Lights On Reminder on page 3-67 for additional information. Daytime Running Lamps (DRL) 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. The DRL system will make the turn signal lamps come on when the following conditions are met: Clean the light sensor window, periodically, using glass cleaner on a soft cloth. Gently wipe the sensor window. Do not spray glass cleaner directly on the surface of the sensor window. Wiper Activated Headlamps This feature activates the headlamps and parking lamps after the windshield wipers have been in use for about six seconds. For this feature to work, automatic lighting must be enabled. See Headlamps on page 3-31 for additional information. When the ignition is turned off, the wiper-activated headlamps will immediately turn off. They will also turn off if the windshield wiper control is turned off. • It is still daylight and the ignition is on, • the automatic lights are enabled, and • the transmission is not in PARK (P). When DRL are on, only your front turn signal lamps will be on. No other exterior lamps will be on when the DRL are being used. Your instrument panel will not be lit. 3-35
