Adjusting main headlights

Information 

• The distance between the headlights and the adjustment unit should be as small as possible! 
• It should not exceed 30 cm, because at greater distances it is no longer possible to define the formation of the light/dark limit in the adjustment unit clearly! 

The vehicle must be on a horizontal surface!

Make the adjustment with the regulator switch set to 0 (headlight beam adjustment)!

Use a standard 5 mm ball-head screwdriver to make the headlight adjustment (free blade length 150 mm).

Only the lower screw may be turned for height adjustment; for lateral adjustment the upper and lower screws must be turned in the same direction and for the same number of rotations!

Make the adjustment with the vehicle ready for driving (fuel tank full, driver's seat occupied by a person or →: 75 kg  , the tyre pressure must correspond to the specified values) using a headlight adjustment unit.

2. Turn on the ignition, turn on dipped beam and high beam headlights.
3. Check setting and adjust if necessary.

   Adjusting: 

   Set 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 height/side adjustment of the dipped beam/high beam.

4. 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.
5. Next, perform the horizontal adjustment of the dipped beam headlights.

   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.

7. After this, the adjustment must be checked again.
8. Fit the carpet again and insert plastic nut.
