vertex of the angle formed in each beam image
should align with the vertical and horizontal
centerlines (8 and 9).
The left and right headlamps must be adjusted
individually.
Note:
If it is not possible to obtain a proper headlamp
adjustment, have the system checked at your authorized
Mercedes-Benz Center.
