Automatic Light Control (ALC) When it is dark enough outside, your Automatic Light Control (ALC) will turn on your headlamps at the normal brightness along with other lamps such as the taillamps, sidemarker, park lamps and the instrument panel lights. The radio lights will also be dim. Your vehicle is equipped with a light sensor on the top of the instrument panel under the defroster grill, so be sure it is not covered which will cause the ALC system to be on whenever the ignition is on. The ALC system may also be on when driving through a parking garage, heavy overcast weather or a tunnel. This is normal. There is a delay in the transition between the daytime and nighttime operation of the DRL and the ALC systems so that driving under bridges or bright overhead street lights does not affect the system. The DRL and ALC systems will only be affected when the light sensor sees a change in lighting lasting longer than this delay. To idle your vehicle with the ALC system off, set the park brake while the ignition is off. Then start the vehicle. The ALC system will stay off until you release the park brake. As with any vehicle, you should turn on the regular headlamp system when you need it. Fog Lamps (If Equipped) The button for your fog lamps is on the instrument panel, to the left of the steering wheel, beside the instrument panel intensity control. When using fog lamps, the ignition must be on as well as the parking lamps or the low-beam headlamps. Push the button to turn the fog lamps on. An indicator light on the button will glow when the fog lamps are on. Push the button again to turn the fog lamps off. The fog lamps will turn off whenever the high-beam headlamps are turned on. When the high beams are turned off, the fog lamps will come on again. 2-36
