Ensure the vehicle is on a level surface and that the headlights are clean.

2. Adjust the Headlight Aim

Locate the Adjustment Screws:
- Open the hood and locate the headlight assembly.
- Identify the headlight adjustment screws, typically found on the top and side of the headlight housing.
Vertical Adjustment:
- Use a flathead screwdriver to turn the vertical adjustment screw.
- Turn clockwise to raise the beam and counterclockwise to lower it.
- Adjust until the beam is level with the marked line on the wall.
Horizontal Adjustment:
- Use the flathead screwdriver for the horizontal adjustment screw.
- Turn clockwise to direct the beam to the right and counterclockwise to direct it to the left.
- Aim the beam so that it is parallel to the centerline of the vehicle.
Final Check:
- After adjustments, step back and recheck the beam pattern against the wall.
- Ensure the beam is properly aligned for optimal visibility without blinding oncoming traffic.
