When the DRL are on, your low-beam headlamps will be on at a reduced brightness. The taillamps, sidemarker and other lamps will not be on. Your instrument panel will not be lit up either. When you turn the exterior lamp band to the headlamp position, your low-beam headlamps will come on. The other lamps that come on with your headlamps will also come on. When you turn off the headlamps, the regular lamps will go off, and the low-beam headlamps will come on at the reduced brightness. To idle your vehicle with the DRL off, set the parking brake. The DRL will stay off until you release the parking brake. As with any vehicle, you should turn on the regular headlamp system when you need it. Fog Lamps If your vehicle has this feature, use your fog lamps for better visibility in foggy or misty conditions. The button for your fog lamps is located next to the instrument panel brightness control. Push the top of the button to turn the fog lamps on. Push the top of the button again to turn the fog lamps off. When using fog lamps, the parking lamps or low-beam headlamps must be on. A light on the button will come on while the fog lamps are on. Fog lamps will go off while the high-beam headlamps are on. Continuous use of the fog lamps will shorten bulb life. Limit use as necessary. 3-13
