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 both front turn signal lamps turn on when the following conditions are met: • The ignition is on. • The exterior lamp control is turned to AUTO. In addition, Canadian vehicles DRL will also turn on if you have turned on your parking lamps. • The light sensor detects daytime light. • The shift lever is not in PARK (P). While the DRL system is on, the taillamps, sidemarker lamps, and instrument panel lights will not be illuminated. The DRL system will be off any time your vehicle is in PARK (P). The DRL system on U.S. vehicles can also be turned off by using the Off/On switch for one ignition cycle. As with any vehicle, you should turn on the regular headlamp system when you need it. Automatic Headlamp System When it is dark enough outside, your automatic system will turn on your headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, parking lamps, instrument panel lights, and interior switch backlighting. Your vehicle is equipped with a light sensor on the top of the instrument panel that inputs to the ACC, so be sure it is not covered which will cause the system to be on whenever the ignition is on. The system may also be on when driving through a parking garage, heavy overcast weather or a tunnel. This is normal. There is a delay in the transition between the daytime and nighttime operation of the automatic lamp control system so that driving under bridges or bright overhead street lights does not affect the system. The automatic lamp control system will only be affected when the light sensor sees a change in lighting lasting longer than this delay. If you start your vehicle in a dark garage, the automatic lamp system will come on immediately. Once you leave the garage, it will take about one minute for the automatic lamp system to change to DRL if it is light outside. 3-17
