When it is bright enough outside, the regular lamps go off, and the front turn signal lamps will take over. If the vehicle is started in a dark garage, the automatic headlamp system comes on immediately. Once the vehicle leaves the garage, it takes 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 the instrument panel brightness knob is in the full bright position. See Instrument Panel Brightness on page 4-15 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). See DIC Warnings and Messages on page 4-51. 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. The regular headlamp system should be turned on when needed. To turn off the DRL, turn the exterior lamp control to the off position or shift into P (Park). The DRL will stay off until the control is toggled again or the vehicle is shifted out of P (Park). This procedure applies only to vehicles first sold in the United States. Fog Lamps Use fog lamps for better vision in foggy or misty conditions. The fog lamps control is located on the multifunction lever next to the exterior lamp control. # (Fog Lamps): Turning the band to this position will turn the fog lamps on. When you turn the fog lamps on, the fog lamp light will appear on the instrument panel cluster to indicate that the fog lamps and the parking lamps are on. If you turn the high-beam headlamps on, the fog lamps will turn off. They will turn on again when you switch to low-beam headlamps. The ignition must be on for the fog lamps to operate. Some localities have laws that require the headlamps to be on along with the fog lamps. 4-13
