Chevrolet Silverado: Exterior Lighting / 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 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.
If the vehicle is started in a dark garage, the automatic headlamp system comes on immediately. If it is light outside when the vehicle leaves the garage, there is a slight delay before the automatic headlamp system changes to the Daytime Running Lamps (DRL). During that delay, the instrument cluster may not be as bright as usual. Make sure the instrument panel illumination control is in the full bright position. See Instrument Panel Illumination Control.
When it is bright enough outside, the headlamps will turn off or may change to DRL.
The automatic headlamp system turns off when the exterior lamp control is turned
to 
or the ignition is off.
