A Phillips head screwdriver
A flat head screwdriver
A level surface
1. Park the Sonata on a level surface with the headlights facing a wall.
2. Turn on the headlights.
3. Locate the two adjustment screws for each headlight. On the Sonata, these are located on the upper and lower corners of the headlights.
4. Use the Phillips head screwdriver to turn the upper adjustment screw clockwise to raise the headlight beam and counterclockwise to lower it.
5. Use the flat head screwdriver to turn the lower adjustment screw clockwise to move the headlight beam to the right and counterclockwise to move it to the left.
6. Continue adjusting the headlights until the beam is centered on the wall and at the proper height. The beam should be level with the ground and about 2 feet below the top of the headlights.
7. Once you are satisfied with the headlight alignment, turn off the headlights and replace the adjustment screw caps.
