Set marker line {M} on aimer to {e}. Scale graduations on the headlight adjustment device are equal to a gradient in cm at a distance of 10 meters.

Light/dark boundary of headlights in the headlight adjustment device: 

{e} Setting dimension, headlights: 

• Value is indicated on the headlight housing and on vehicles with production date up to 2011 on the type plate in %.

  (e.g.: 1.0 %  = -10 cm/10 m = - 1.0 %  on the headlight adjusting device)

• Value 1.1 %  (adjustment value - 1.1 %  )

Setting dimension, fog lights: 

• Value 2.0 %  = -20 cm/10 m = - 2.0 %  on the headlight adjusting device applies to all BMW Group vehicles.

{H} Height of center of headlight above parking surface.

{h} {H} - {e} = height of marking line above parking surface

+ Central mark = center point of high-beam headlight.
