How do I adjust the headlights on an Audi A7?

The headlights on my Audi A7 seem to be pointing too low and I am having trouble adjusting them. What is the proper procedure for adjusting the headlights?

First, park your car on a flat surface and turn off the headlights. Locate the adjustment screws on the back of the headlight assembly and use a screwdriver to turn them clockwise or counterclockwise to adjust the height of the headlights. Make small adjustments and check the alignment with a wall or garage door. Repeat as needed until the headlights are properly aligned.
