Note
Adjustment
The distance between the headlights and the
adjustment unit should be as small as possible.
It should not exceed 30 cm, because if the
distance is greater, it is no longer possible to
clearly define the formation of the light/dark
limit in the adjustment unit.
Secure the plugs after making the adjustment.
For Litronic headlights the ignition must be
switched off and on after adjustment with the
lights switched on. After this, the adjustment
must be checked again.
Note
Set the headlight adjustment unit to
10 cm/10 m (1 %).
1. First, make the vertical adjustment of the
dipped beam headlights. To do this, line up
the lighVdark borderline running upwards
at an angle on the right hand side with the
dotted 150 line of the adjustment unit.
