Autolight system
The autolight system allows the headlights to turn on and off automatically. The autolight system can:
Turn on the headlights, front parking, tail, license plate and instrument panel lights automatically when it is dark. Turn off all the lights (except daylight running lights) when it is light. Keep all the lights on for a period of time after you place the ignition switch in the OFF position and all doors are closed.
