63 10... Test requirements for headlights vertical aim adjustment

IMPORTANT: Do not perform headlight adjustment immediately after lowering the vehicle on the vehicle hoist. In this case, move the vehicle for approx. 15 m on its own wheels before adjustment.
IMPORTANT: Do not move the vehicle and steering wheel during the measuring and adjustment procedures! 
IMPORTANT: A correct measurement/adjustment requires exact positioning of the headlight adjustment device!
This applies to all headlights!

Place the headlight adjustment device (1) centered in front of the vehicle.

Distance to the headlight: 30 - 50 cm 

Position the headlight adjustment device (1) vertically to the vehicle longitudinal axis. For this purpose, the laser beam (2) must hit two suitable points, e.g. points marked with arrows.

IMPORTANT: Points must be vehicle proof!
Trim panels are not suitable!

If the headlight adjustment device (1) does not have a laser beam (1), complete the alignment analogous with the line in the mirror.

The center of the collecting lens (1) must match the center of headlight (2) horizontally.

Corrections are made by raising or lowering the headlight adjustment device.

When positioned correctly, the light/dark boundary of the headlight (marked with arrow) must hit the collecting lens of the adjusting device in the center:

  1. The headlight adjusting device is too low.
  2. The headlight adjusting device is positioned correctly.
  3. The headlight adjusting device is too high.

The center of the collecting lens (1) must match the center of headlight (2) vertically.

Corrections are made by sliding the side of the headlight adjusting device to the left or right.
