Chevrolet Silverado: Exterior Lighting / Daytime Running Lamps (DRL)

DRL can make it easier for others to see the front of the vehicle during the day. Fully functional DRL are required on all vehicles first sold in Canada.

The DRL system comes on when the following conditions are met:

• The ignition is on.
• The exterior lamp control is in AUTO.
• The transmission is not in P (Park).
• The light sensor determines it is daytime.

When the DRL system is on, only the DRL are on. The taillamps, sidemarker lamps, instrument panel lights, and other lamps will not be on.

When it begins to get dark, the automatic headlamp system switches from DRL to the headlamps.

To turn off the DRL, turn the exterior lamp control to O and then release. For vehicles first sold in Canada, off will only work when the vehicle is parked.
