1. Install the car perpendicular to a smooth wall (e.g. garage) at a distance of 5 m. Place a weight of 75 kg on the driver's seat. Mark the screen on the wall as shown. Measure the distance from the center of the headlights to the floor. This will be the distance h on the screen. The longitudinal plane of symmetry of the car must pass along line 0 on the screen.
2. Turn the headlight adjustment knob to position "driver and front passenger" and turn on the low beam.
3. Adjust the direction of the light spot separately for each headlight. During adjustment, cover the second headlight with an opaque cloth.
4. Adjust with screws 1 (in the horizontal plane) and 2 (in the vertical plane) the position of the light spot for each headlight, if the location of the light spots on the screen does not match the figure.
5. The headlights are considered adjusted if the upper border of the left parts of the light spots coincides with the line N, and the vertical lines A and B pass through the points C1 and C2 of the intersection of the horizontal and inclined sections of the light spots.
