  Note

Use fuel containers filled with water as additional weight (a five liter fuel container filled with water weighs five kg).

• The electromechanical parking brake must not be engaged so vehicle is not under stress.
• The vehicle and headlamp adjusting unit must be on a level surface.
• The headlamp adjusting unit must be aligned to the vehicle. Refer to the Headlamp Adjusting Unit Instructions.
• The headlamp adjuster must be distance -a- 30 to 70 cm (11.81 to 27.55 in.) in front of the headlamp and should not deviate more than dimension -b- = 3 cm (1.18 in.) from the headlamp center point.
• The inclination dimension is set on the headlamp adjusting unit. Refer to the Headlamp Adjusting Unit Operating Instructions.

• The angle dimension -arrow- is stamped for ECE countries on the upper edge of the headlamp -1- in "%".

  Note

The percentage indicator is based on a 10 meter (32.8 feet) projection distance. At an angle dimension of 1.0%, for example, converts to 10 cm (3.93 in).

Procedure

• 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-.

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

- Then adjust the light-dark border, starting from the bottom, on the dividing line.

- For side adjustment, turn the adjusting screw -2-.

The adjusting screw -2- for the side adjustment must be secured with a plug after the adjustment is made on USA vehicles. For the correct plugs. Refer to the Parts Catalog.
