The 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 Automatic Headlamp System so that driving under bridges or bright overhead street lights does not affect the system. The DRL and Automatic Headlamp Systems will only be affected when the light sensor sees a change in lighting lasting longer than thisdelay. To idle your vehicle with the system off, set the parkin9 brake while the ignition is off. Then start the vehicle. The system will stay off until you release the parking brake. Delayed Headlamps The delayed headlamps feature will continue to illuminate the headlamps for 20 seconds after the key is turned to OFF, then the headlamps will automatically turn off. To override the 20 second delayed headlamp feature while it is active turn the turn signal/muItifunction lever up one position and then back to AUTO. Fog Lamps If your vehicle has this feature, the button for your fog lamps is located on the instrument panel, to the left of the steering wheel, beside the instrument panel brightness thumbwheel.
