Buick Enclave: Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. Fully functional daytime running lamps are required on all vehicles first sold in Canada.
A light sensor on top of the instrument panel monitors the exterior light level for the operation of DRL, so be sure it is not covered.
The DRL system makes the low-beam headlamps turn on at reduced brightness in daylight when the following conditions are met:
• The ignition is on.
• The exterior lamp button for the headlamps is off.
• The automatic transmission is not in P (Park).
When the DRL are on, only the low-beam headlamps will be on. The parking lamps, taillamps, sidemarker and other lamps will not be on.
When it is dark enough outside, the low-beam headlamps will come on. The other lamps that turn on with the headlamps will also turn on. When it is bright enough outside, the regular lamps will go off, and the low-beam headlamps change to the reduced brightness of DRL.
To turn off all exterior lighting at night when the vehicle is parked, turn the exterior lamp control to the off position. The exterior lamps will turn back on automatically when the transmission is moved out of P (Park). See Exterior Lamps for more information.
The regular headlamp system should be turned on when needed.
