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 256 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: • 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. 216 When the automatic lights are enabled and it is dark enough outside, the DRL will turn off and the low-beam headlamps will turn on. When it is bright enough outside, the low-beam headlamps will go off, and the DRL will turn back on. If you start your vehicle in a dark garage, the automatic headlamp system will come on immediately. Once you leave the garage, it will take about one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, your instrument panel cluster may not be as bright as usual. Make sure your instrument panel brightness lever is in the full bright position. See Instrument Panel Brightness on page 220. To operate your vehicle with the DRL off, turn the exterior lamp control off and then do one of the following: • Turn the exterior lamp control to the parking lamp position. • Turn the exterior lamp control to the headlamp position. • Turn the exterior lamp control from AUTO to off and back to AUTO.
