Solution

1. Preparation

Gather necessary tools: Phillips screwdriver and a flathead screwdriver.
Ensure the vehicle is on a level surface with the headlights off.

2. Access Headlight Adjustment Screws

Open the hood of the vehicle.
Locate the headlight assembly where you will find two adjustment screws: one for vertical adjustment (usually on top) and one for horizontal adjustment (usually on the side).

3. Adjust Vertical Alignment

Using a Phillips screwdriver, turn the vertical adjustment screw clockwise to raise the beam and counterclockwise to lower it.
Adjust until the top of the beam is aligned with the mark on the wall.

4. Adjust Horizontal Alignment

Use the flathead screwdriver to turn the horizontal adjustment screw.
Turn clockwise to move the beam right and counterclockwise to move it left.
Ensure that the beam is centered relative to the vehicle’s centerline and aligned with the mark on the wall.

5. Final Check

After adjustments, step back and visually confirm the headlight beam is properly aligned.
Close the hood of the vehicle.
