Solution

1. Preparation

Gather necessary tools: flat-head screwdriver or Torx screwdriver, measuring tape, and a level surface.
Ensure the vehicle is parked on a level surface and the headlights are clean.

2. Access the Headlight Adjusters

Open the hood of the vehicle.
Locate the headlight assembly. The adjustment screws are usually found on the top or side of the headlight housing.

3. Adjust the Vertical Alignment

Using the flat-head or Torx screwdriver, locate the vertical adjustment screw.
Turn the screw clockwise to raise the beam and counterclockwise to lower it.
Adjust until the top of the beam is at the previously marked height on the wall.

4. Adjust the Horizontal Alignment

Locate the horizontal adjustment screw, typically adjacent to the vertical adjuster.
Turn the screw clockwise to move the beam to the right and counterclockwise to move it to the left.
Adjust the beam until it aligns with the horizontal mark on the wall.

5. Final Checks

Turn off the headlights and close the hood.
Recheck the headlight beam alignment by repeating the measurement and observation process as necessary.
