When it is dark enough outside, the front turn signal lamps will turn off and normal low-beam headlamps will turn on. When it is bright enough outside, the regular lamps will go off, and the front turn signal lamps will take over. 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 approximately one minute for the automatic headlamp system to change to DRL if it is light outside. During that delay, the instrument panel cluster may not be as bright as usual. Make sure your instrument panel brightness knob is in the full bright position. See Instrument Panel Brightness on page 170 for more information. If it is dark enough outside and the exterior lamp control is off, a HEADLAMPS SUGGESTED message will display on the Driver's Information Center (DIC). This message informs the driver that turning on the exterior lamps is recommended. See DIC Warnings and Messages on page 212. Turning the exterior lamp control to off a second time, or turning on the headlamps will remove the HEADLAMPS SUGGESTED message in the DIC. If the parking lamps or the fog lamps were turned on instead, the HEADLAMPS SUGGESTED message will continue to be displayed. As with any vehicle, you should turn on the regular headlamp system when you need it. To turn off the DRL, turn the exterior lamp control to the off position or shift into PARK (P). The DRL will stay off until the control is toggled again or the vehicle is shifted out of PARK (P). This procedure applies only to vehicles first sold in the United States. 168
