Solution

1. Preparation

Tools Required:
- Screwdriver (Phillips or flathead, depending on the adjustment screws)
- Tape measure
Ensure the vehicle is parked on a flat surface and the headlights are clean.

2. Locate Adjustment Screws

Open the hood and locate the headlight assembly.
Identify the adjustment screws, typically found on the top and/or side of the headlight housing.

3. Adjust the Headlights

Vertical Adjustment:
- Turn the vertical adjustment screw (usually marked with a "+" for up and "-" for down) to raise or lower the headlight beam until it aligns with the marked line on the wall.
Horizontal Adjustment:
- Turn the horizontal adjustment screw to move the beam left or right. Align the beam with the centerline marked on the wall.

4. Final Check

Step back and visually inspect the alignment of the headlight beams to ensure they are symmetrical and at the correct height.
Make further adjustments if necessary, repeating the measurement and adjustment steps.
