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

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

The adjustment procedure for the test screen without the 15° adjustment line also applies to the previous test screen with the 15° adjustment line. To avoid incorrect adjustments, ignore the 15° adjustment line -arrow-.
