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 3-39. To operate your vehicle with the DRL off, turn the exterior lamp control off and then do one of the following: Light Sensor • Turn the exterior lamp control to the parking lamp position. • Turn the exterior lamp control to the headlamp position. The light sensor for the DRL is located on top of the instrument panel. If you cover the sensor, it will read dark, and the exterior lamps may come on when you do not need them. • Turn the exterior lamp control from AUTO to off and back to AUTO. An AUTOMATIC LIGHTS OFF message will appear on the DIC, showing that automatic lighting has been disabled. As with any vehicle, you should turn on the regular headlamp system when you need it. 3-36
