How do you adjust Kia Optima headlights?

To adjust the headlights on a Kia Optima, first park the vehicle on a level surface about 25 feet from a wall. Turn on the headlights and mark the center of the light beams on the wall with tape. Use a screwdriver to adjust the vertical and horizontal alignment screws located on the headlight assembly until the beams are at the correct height and angle, typically slightly below the center of the marks. Always check the owner's manual for specific adjustment instructions and specifications.
