Buick Regal: Headlamp Aiming - Vehicle Care - Buick Regal Owners ManualBuick Regal: Headlamp Aiming

Headlamp aim has been preset at the factory and should need no further adjustment.

However, if the vehicle is damaged in a crash, the headlamp aim may be affected. Aim adjustment to the low-beam headlamps may be necessary if oncoming drivers flash their high-beam headlamps at you (for vertical aim).

If the headlamps need to be re-aimed, it is recommended that the vehicle be taken to a dealer for service.
