The DRL system will make your low-beam headlamps come on at a reduced brightness when the following conditions are met: Fog Lamps D D D D The ignition is on, the headlamp switch is off, the transaxle is not in PARK (P) and the parking brake is released. When the DRL are on, only your low-beam headlamps, at a reduced brightness, will be on. The taillamps, sidemarker and other lamps won't be on. Your instrument panel won't be lit up either. When it's dark enough outside, your headlamps will change to full brightness. The other lamps that come on with your headlamps will also come on. When it's bright enough outside, the regular lamps will go out, and your low-beam headlamps change to the reduced brightness of DRL. To idle your vehicle with the DRL off, set the parking brake while the ignition is in OFF or LOCK. Then start your vehicle. The DRL will stay off until you shift out of PARK (P) and release the parking brake. As with any vehicle, you should turn on the regular headlamp system when you need it. The fog lamp switch is located in the upper corner of the instrument panel, to the left of the instrument panel cluster. To turn the fog lamps on, press the right side of the fog lamp switch. A light will glow on the switch to let you know that they are on. (The parking lamps must be on, or the fog lamps won't come on.) Press the left side of the switch to turn the fog lamps off. The fog lamps will go off whenever you change to high-beam headlamps. When you return to low beams, the fog lamps will come on again. 2-53
