Headlight Adjustment - Porsche 928 1982 Owner's Manual

Headlight adjustment

Headlight adjustment should be done with
a headlight aiming device under the follow-
ing conditions:
At curb weight of car (i. e. car ready for use
and with full fuel tank).
Driver's seat should be occupied by a per-
son or a weight of approx. 155 lbs (70 kg).
Tire pressure must be correct.
Roll car forward a few feet so that the sus-
pension seeks its normal position.
Adjustment screws
Each headlight and fog light has two adjust-
ing screws, one for lateral setting, and one
for vertical. By turning these screws left or
right, the corresponding adjustment in beam
position is effected.
Screw "a" (lateral adjustment)
right turn = beam moves right
left turn = beam moves left
Screw "b" (vertical adjustment)
right turn = beam moves up
left turn = beam moves down
