When it is dark enough outside, the DRL will turn off and the vehicle's headlamps and parking lamps will turn on. The other lamps that come on with the headlamps will also come on. When it is bright enough outside, the headlamps will go off and the DRL will come on. To idle the 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. This feature is not available for vehicles first sold in Canada. To turn off the automatic headlamp feature when it is dark outside, move the exterior lamp control to the parking lamp position. The parking lamps remain on and the headlamps turn off. The fog lamps also go on if they were on previously. As with any vehicle, the regular headlamp system should be turned on when needed. 160 Fog Lamps If your vehicle has fog lamps, the button is located in the center of the exterior lamps control on the left side of the steering column. Press the fog lamps button to turn the lamps on or off. While the high-beam headlamps are on, the fog lamps are off. Some localities have laws that require the headlamps to be on along with the fog lamps. Exterior Lighting Battery Saver If the parking lamps or headlamps have been left on after the ignition has been turned to off, the exterior lamps will turn off after about 10 minutes. This protects the battery from being drained. Use the exterior lamp control to turn the lamps back on, if they are still needed.
