Wiper Activated Headlamps This feature, if equipped, will automatically activate the headlamps and parking lamps after the windshield wipers have been in use for about 30 seconds and when all of the following conditions are met. • The exterior lamp control is in AUTO. • The headlamps have not already been activated by automatic lighting. • The automatic lighting feature has not been disabled using the exterior lamp control. See Exterior Lamps on page 181 for additional information. If the wipers are activated for over 30 seconds and the exterior lamp control is in the parking lamps position, or the automatic lighting feature has been disabled using the exterior lamp control, a HEADLAMPS SUGGESTED message will appear on the Driver Information Center, if equipped. Headlamps on Reminder If you turn the ignition to LOCK while leaving the lamps on, you will hear a warning chime once the driver's door is opened. 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 will make front parking and turn signal lamps come on in daylight when the following conditions are met: • The ignition is on. • The exterior lamps control is off. 182
