Daytime Running Lamps (Drl)/Automatic Headlamp System; Adaptive Forward Lighting System - Buick Enclave 2008 Owner's Manual

Daytime Running Lamps (DRL)/
Automatic Headlamp System
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
first sold in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it is not covered.
The DRL system's automatic control will make the DRL
lights come on when the following conditions are met:
•
The ignition is in the ON position.
•
The exterior lamps control is in AUTO.
•
The engine is running.
When the DRL are on, only the DRL lights will be on.
The headlamps, taillamps, sidemarker, and other lamps
will not be on. The instrument panel and cluster will
also not be lit.
When it is dark enough outside, the DRL lights will turn
off and the headlamps and parking lamps will turn
on. The other lamps that come on with the headlamps
will also come on.
3-16
When it is bright enough outside, the headlamps will go
off and the DRL will come on.
As with any vehicle, you should turn on the regular
headlamp system when it is needed.

Adaptive Forward Lighting System

Vehicles with the Adaptive Forward Lighting System
(AFS) have headlamps that swivel to the left or right when
making a turn to provide better lighting. To enable AFS,
set the exterior lamp switch to the AUTO position. Move
the switch out of the AUTO position to turn off the system.
See Exterior Lamps on page 3-14.
AFS operates when the vehicle speed is greater
than 2 mph (3 km/h). AFS does not operate when the
transmission is in REVERSE (R). AFS is not immediately
operable after starting the vehicle; driving a short
distance is required to calibrate the AFS.
