How do you adjust the headlight beam located on a 2005 Nissan Altima?

To adjust the headlight beam on a 2005 Nissan Altima, park the vehicle on a level surface about 25 feet from a wall. Turn on the headlights and mark the center of the beam on the wall with tape. Use a screwdriver to adjust the vertical and horizontal screws located on the headlight assembly until the top of the beam is aligned with the tape mark and the beam is centered horizontally. Make sure to check the alignment for both headlights.
