Setting

Note
• Set the headlight adjustment unit to 10 cm/10 m (1%)!
• With this alignment, preference must be given to the central zone around the salient point of the
light/dark limit!
First, make the vertical adjustment of the dipped beam headlights.
1. To do this, line up the light/dark borderline running upwards at an angle on the right−hand side with the
dotted 15° line of the adjustment unit.
Next, perform the horizontal adjustment of the dipped beam headlights.
2. To do this, line up the left, horizontal section of the light/dark limit (when driving on the right) with the
dotted horizontal line of the adjustment unit.
Note
• 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 define the
formation of the light/dark limit in the adjustment unit clearly!
3. Secure the plugs after making the adjustment.
4. In the case of Xenon headlights, the ignition must be switched off and on after the adjustment has been
made with the lights switched on.
5. After this, the adjustment must be checked again.
