GMC Terrain: Exterior Lighting / Daytime Running Lamps (DRL)

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

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

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

When the DRL are on, the taillamps, sidemarker lamps, instrument panel lights, and other lamps will not be on. The instrument cluster will be lit.

The DRL turn off when the headlamps are turned to or the ignition is off. For vehicles first sold in Canada, the DRL can only be turned off when the vehicle is parked.

The regular headlamp system should be turned on when needed.
