Buick LaCrosse: Automatic Headlamp System
When the exterior lamp control is set to AUTO and it is dark enough outside, the headlamps come on automatically.
There is a light sensor located on top of the instrument panel. Do not cover the sensor; otherwise the headlamps will come on when they are not needed.
The system may also turn on the headlamps when driving through a parking garage or tunnel.
When it is bright enough outside, the headlamps will turn off or may change to Daytime Running Lamps (DRL).
The automatic headlamp system turns off when the exterior lamp control is turned to or the ignition is off.
