Adjusting HeadlightsfPlease see the chapter “LIGHTS, REPLACING
BULBS” on Page 219.
Adjustment
The adjustment is made with 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
vertical position of the cutoff of the low beam (see
fig.) has to be projected on a vertical 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 performed at not less than
24.6 ft. (7.5 m) (this value is a rounded down
conversion 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 viewing screen.
