Cleaning the IntelliBeam™ Light Sensor The light sensor is located on the inside of the vehicle in front of the inside 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. 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: • It is still daylight and the ignition is on. • The exterior lamp control is in the off position. • The transaxle is not in PARK (P) (United States only). • The light sensor is covered or not detecting light. See "Sensors" under Dual Climate Control System on page 204. 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 are turned on and have completed eight wipe cycles within four minutes. When the ignition is turned to OFF, the wiper-activated headlamps immediately turn off. The wiper-activated headlamps also turn off if the windshield wipers are turned off. 190
