Porsche 911 Carrera - Manual (Page 320)

Adjusting Headlights
Adjustment
Please observe the chapter ”LIGHTS, REPLAC-
ING BULBS” on page 302.
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 lowbeam (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 in. (5 cm) at 24.6 ft. or 7.5 m (0.4) below a
horizontal line, x in. (cm) from ground to the center
of the headlamp lens.
