Buick Enclave: Daytime Running Lamps (DRL)/Automatic Headlamp System. Delayed Headlamps. Adaptive Forward Lighting (AFL)
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. The DRL system makes the low-beam headlamps come on at a reduced brightness when
the following conditions are met: When the DRL are on, the regular headlamps, taillamps, sidemarker, and other
lamps will not be on. The instrument panel and cluster will also not be lit. The headlamps automatically change from DRL to the regular headlamps depending
on the darkness of the surroundings. The other lamps that come on with the headlamps will also come on. When it is bright enough outside, the headlamps will go off and the DRL will
come on. The regular headlamp system should be turned on when needed. Do not cover the light sensor on top of the instrument panel because it works
with the DRL. Delayed headlamps provide a period of exterior lighting as you leave the area
around the vehicle. This feature is activated when the headlamps are on due to the automatic headlamps
control feature, and when the ignition is turned off. The headlamps remain on until
the exterior lamps control is moved to the parking lamps position or until the pre-selected
delayed headlamp lighting period has ended. If the ignition is turned off with the exterior lamp control in the parking lamps
or headlamps position, the delayed headlamps cycle will not occur. To disable the delayed headlamps feature or change the time of delay, see Vehicle
Personalization . Vehicles with the Adaptive Forward Lighting System (AFL) have headlamps that
swivel to the left or right when making a turn to provide better lighting. To enable
AFL, set the exterior lamp switch to the AUTO position. Move the switch out of the
AUTO position to turn off the system. See Exterior Lamp Controls . AFL operates when the vehicle speed is greater than 3 km/h (2 mph). AFL does
not operate when the transmission is in R (Reverse). AFL is not immediately operable
after starting the vehicle; driving a short distance is required to calibrate the
