Adjusting HeadlightsfPlease see the chapter “LIGHTS, REPLACING
BULBS” on Page 247.
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.
