Can someone help me, I must be misunderstanding something in the owners manual. I want to adjust my headlight which are currently poorly aimed. Went to the owners manual and found this page. But it seems that vertical and lateral are backwards. Under the Vertical (screw A) section it says it moves the beam left and right and under the Lateral section (screw B) is says it move the beam up and down.

So, does anybody know which screw does what? Thanks, I know I can just try one, but I would like to adjust it properly from the start without testing which does what.

Thanks

 

They change the angle of your headlight beams.

A (bottom screw) = up or down, B (top screw) = left or right

edit: wording is consistent for both screws

 

From reading the owners manual section in your picture it seems something was lost in the translation. If you just use the DOT aiming procedure and use whichever screw moves the beam to match it that is all that matters:

my reply from 2007:

993 specific: Porsche recommends the 10 x 10 for the 993
park your car on a flat surface with a wall facing you. The distance between the car and
the wall should be 10 meters (32.8080 feet)
Now measure the height from the floor to the center of your headlight inner small lense.
Now go to the wall and mark the wall with the height of the headlights small lens minus (10 centimeters)
or 3.937 inches.
Now to adjust the drivers headlight, raise or lower the horizontal line drawn by the light to the mark on the wall.
For left and right adjust, you could clearly see a checkmark style beam on the wall to the right. This checkmark should be centered to the center of the car. ie the beams should look like this:

left and right beam pattern on wall

-----------------------/-----------------------/
________________/________________/

..(steering wheel)



Now the right beam should lye on the left one (straight line) with the swoosh equidistant.
Then you could adjust the fog lights. Those should fill the dark area BELOW the headlights beam.
You would be able to see clearly where the bottom of the headlight beam stops, so raise the fog light beam
to exactly fill the gap.

ps: I have litronics ROW, so application may differ to other countries
For 993's with electrical adjustable headlights, remember to place switch on zero Before
adjusting,
