How do you adjust headlights on a 2006 Cadillac SRX?

To adjust the headlights on a 2006 Cadillac SRX, first 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. Using a screwdriver, adjust the vertical and horizontal alignment screws located at the back of each headlight assembly until the beam is centered and level with the marks. Ensure both headlights are aligned symmetrically for optimal visibility.
