Please check the following:
–  With the low beam on, check if the horizontal light-dark limit touches the separation limit -1- of the test surface.
   
–  Check if the point of inflexion -2- between the left horizontal section and the right ascending section of the light-dark limit runs vertically through the central mark -3-. In this case, the light core of the light beam is at right of the vertical line.
  Note
t  Line -1- is the measurement from the ground to the centre of the headlight, minus 4.72 in for a distance of 10.94 yd.
t  Line -1- is the measurement from the ground to the centre of the headlight, minus 2.36 in for a distance of 5.47 yd.
t  For an easier determination of the breaking point -2-, cover and then release the left half of the headlight (seen from the driver's side). Then, test the low beam once more.
t  After correctly adjusting the low beam, the high beam is automatically adjusted. This means that the high beam centre must be on the headlight central mark -3-. A 200-mm deviation to the right or to the left, 150 mm upwards and 100 mm downwards is acceptable.
