Headlight AdjustmentfCheck tire pressure and adjust if necessary.
fPlease observe the chapter “TIRE PRESSU-
RES, COLD” on Page 385.
fPlease observe the chapter “REPLACING BUL-
BS” on Page 360.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
165lbs. (75kg) 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 vertical screen (wall) in
distance of 7.5 m (24.6 ft.) from the front lens of
the headlamp.The correct position of the cutoff is
7.5 cm (3.0 in.) at 7.5 m or 24.6 ft. (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
7.5 m (this value is a rounded down conversion
from the 25-foot distance typical of field aim using
a screen). The 7.5 m (24.6 ft.) distance is meas-
ured from the headlamp lens to the viewing
screen.
Floor
The surface upon which the vehicle rests is flat
and approximately level.
Screen
The screen upon which headlamp beams are pro-
jected is perpendicular to the floor and the vehi-
cle's longitudinal axis, flat, uniformly light in color,
unobstructed, and wide and high enough to ac-
commodate the vehicle beam patterns to be
aimed.
The screen should be wide enough to provide at
least 3.3 ft. (1 m) of space outboard of the vehi-
cle's headlamp spacing.

Height adjustment for low beam/
high beam and additional high beam1. Push down cover in the engine compartment
and remove.
2. Switch ignition on.
3. Switch on low beam and/or high beam.
4. Adjust low beam in direction of the arrow.
Changing Headlights from Left to
Right-Hand TrafficIf you travel to a corresponding country where traf-
fic uses the other side of the road, the headlights
must be partially masked with films when you
cross the border.
fYou can obtain the films and a set of instruc-
tions from an authorized Porsche dealer.
