How do I adjust the headlights on an Audi A8?

I've noticed that the headlights on my Audi A8 seem to be pointed too low. How can I adjust them to improve visibility?

To adjust the headlights on your Audi A8, first find the headlight adjustment screws located on the top and sides of the headlight housing. Turning these screws clockwise will raise the headlights and counterclockwise will lower them. Remember to adjust both headlights and check them against a garage door or wall to ensure they are even.
