Adjusting HeadlightsfPlease see the chapter “LIGHTS, REPLACING 
BULBS” on Page 257.
Adjustment 
The adjustment is made wi th the vehicle ready to 
drive and the fuel tank completely filled. 
The driver’s seat must be loaded by a person or a 
165 lbs. (75 kg) weight and the tire pressures 
must meet the prescribed values. 
After being loaded, the car must be rolled a few 
meters so that the suspension can settle. 
For checking the headlight adjustment, the verti-
cal position of the cutoff of the lowbeam (see fig.) 
has to be projected on a ve rtical screen (wall) in 
distance of 24.6 ft. (7.5  m) from the front lens of 
the headlamp.
The correct position of the cutoff is 2.0 in. (5 cm) 
at 24.6 ft. or 7.5 m (0.4 °) below a horizontal line, 
x  cm from ground to the center of the headlamp 
lens. Lateral adjustment of the
 headlights should be 
carried out at a specialist workshop with an optical 
adjustment unit. 
Distance 
Visual aim shall be perf ormed at not less than 
24.6 ft./7.5 m (this value is a rounded down con-
version from the 25-foot distance typical of field 
aim using a screen). The 24.6 ft./7.5 m distance 
is measured from the headlamp lens to the view-
ing screen.
