-- Switch on low beams.

The horizontal light-dark border must touch the dividing line -1- on the adjusting unit test surface.
The point -2- between the left horizontal part and the right vertical part of the light-dark border must run vertically through the central mark -3-. The bright core of the light beam must be to the right of the vertical.

NOTE:

To determine the inflection point -2- more easily, cover and uncover the left half of the headlamp several times. Then check the low beam again.

After correct headlamp adjustment, the center of the high beam light beam must be on the central marking -3-.

-- To adjust the height of the headlamp, set the light-dark border just under the dividing line with the adjustment screw -1-.
