Adjusting Headlights - Porsche Boxster Owner's Manual

Adjusting Headlights

Adjustment
Please observe the chapter "REPLACING
BULBS" on page 275.
Please observe the chapter "TIRE PRESSURE
FOR COLD TIRES" on page 304.
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 2.0 in. (5 cm) at 24.6 ft. or 7.5 m (0.4°) below a
horizontal line, x in. from ground to the center of
the headlamp lens.
