Buick LaCrosse: Adaptive Forward Lighting (AFL)
The Adaptive Forward Lighting System (AFL) pivots the headlamps horizontally to provide greater road illumination while turning. To enable AFL, set the exterior lamp switch to the AUTO position. Moving the switch out of the AUTO position deactivates the system. 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 AFL. See Exterior Lamp Controls.
