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 headlamps when you need them. Headlamps Dim to Park This feature works when the ignition is on and it is dark outside. To turn the headlamps off when it is dark outside, turn the exterior lamps control to the parking lamp position. In this position, the parking lamps, sidemarker lamps, taillamps, license plate lamps and instrument panel lights will be on, but the headlamps will be off. To turn on the headlamps along with the other lamps when it is dark outside, turn the exterior lamps control to the AUTO or headlamp position. Delayed Headlamps The delayed headlamps feature will continue to illuminate the headlamps for 20 seconds after the key is turned to OFF at night. Then the headlamps will automatically turn off. To override the 20 second delayed headlamp feature while it is active turn the switch at the end of the turn signal/multifunction lever up one position and then back to AUTO. 2-42
