yellowblue A flashing DRL telltale indicates a possible burned out headlamp, or that the vehicle may need service to repair a stuck DRL relay. When the DRL are on, only your high-beam headlamps will be on at reduced brightness. The taillamps, sidemarker and other lamps won't be on. Your instrument panel won't be lit up either. When you turn on the headlamp switch, your high-beam headlamps will go out, and your headlamps will come on. The other lamps that come on with your headlamps will also come on. When you turn off the headlamp switch, the regular lamps will go off, and your high-beam headlamps will come on at 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. Use your fog lamps for better vision in foggy or misty conditions. The switch for your fog lamps is next to the instrument panel intensity control. Push the top of the switch to turn the fog lamps on. Push the bottom of the switch to turn the fog lamps off. When using fog lamps, the parking lamps or low-beam headlamps must be on. Fog Lamps (If Equipped) 2-43
