2022 Buick Envision Owners Manual - Daytime Running Lamps (DRL)

Daytime Running Lamps (DRL)

DRL can make it easier for others to see the front of the vehicle during the day.

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

  • The ignition is on.
  • The exterior lamp control is in AUTO.
  • 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 the off position and then release.

For vehicles first sold in Canada, off will only work when the vehicle is parked.


To flash the high beams, pull the turn signal lever toward you, and release.
