Good afternoon, here is the info you requested:
The low beam headlamp will project on the screen upper edge of the beam (cut-off) at the horizontal lamp centerline ± 50 mm (2 in.). Horizontal aim is preset and can not be adjusted. The high beam pattern should be correct when the low beams are aligned properly .
To adjust headlamp vertical alignment, rotate adjustment screw to achieve the specified low beam cut-off location.
Let me know if I can help you further
