Attention! The direction of the headlight beams should be such that the road in front of the car is well lit, and the drivers of oncoming vehicles are not blinded when the dipped beam is turned on. A flat vertical surface is required to complete the work (screen) size 2x1 m and assistant (or a load weighing 75 kg).
Execution sequence
1. We install a fully charged and equipped (spare wheel, tool, jack) car on a flat horizontal platform at a distance of 5 m perpendicular to the screen (length - 2 m, height - 1 m).
2. Check and, if necessary, set the required tire pressure (see "Tires - pressure check").
3. We shake the car from the side, for uniform installation of suspension springs.
Screen layout for headlight adjustment: a - external: C - a horizontal line corresponding to the centers of the headlights; D - line passing through the centers of light spots; A and B - vertical lines corresponding to the centers of the headlights; O - center line; h is the distance of the headlight centers from the floor; l - distance between the centers of the outer headlights; b - internal: C - a horizontal line corresponding to the centers of the headlights; F - line passing through the centers of light spots; A1 and B1 - vertical lines corresponding to the centers of the headlights; O - center line; h is the distance of the headlight centers from the floor; l - distance between the centers of the inner headlights
4. Apply markup on the screen (see diagram). The vertical line O coincides with the plane of symmetry of the car. Vertical lines A and B pass through the points corresponding to the centers of the outer headlights, and A1 and B1 - the inner ones. The distance between the centers of the outer headlights is 1180 mm, the inner one is 840 mm. The upper horizontal line C is drawn at the height of the center of the headlights from the surface of the site. Below it we draw lines of centers of light spots. Line D for external headlights at a distance of 100 mm, line F for internal headlights at a distance of 50 mm.
5. Remove headlight trims (see "Facing and grille - removal and installation").
6. An assistant sits on the driver's seat or a load is placed.
7. Turn on the dipped beam.
8. Close the right outer headlight with a piece of cardboard or cloth.
9. With a Phillips screwdriver, turning the light beam adjustment screw in the vertical direction, we combine the upper horizontal border of the light beam with line D of the center of the light spots.
10. Rotating the screw for adjusting the light beam in a horizontal direction with a Phillips screwdriver, we combine the break point of the upper boundary of the light beam with the intersection point of lines D and A.
11. Similarly, we adjust the right headlight.
12. To adjust the internal headlights, turn on the high beam and close the external headlights.
13. Alternately closing the internal headlights, rotate the adjusting screws with a Phillips screwdriver, setting the centers of the light spots at the intersection of lines F and A1 (or B1).
14. Turn off the headlights and install the lining in place.
