WARNING: Do not neglect headlight adjustment work. In addition to the fact that your car with unadjusted headlights will not pass the instrumental check at the next technical inspection, it will be dangerous on the road for all road users, including you. The actions of a driver blinded by the headlights of an oncoming car are often unpredictable.
You will need a Phillips-head screwdriver.
1. Pre-check and, if necessary, adjust the air pressure in the tires to the correct level.

2. Place the car perpendicular to a smooth wall (e.g. in a garage) at a distance of 3 m. Place an additional weight of 75 kg on the driver's seat. Mark the screen on the wall as shown in Fig. 4.6. The longitudinal plane of symmetry of the car should pass along line 0 on the screen. Rock the car from the side so that the suspension springs self-align.
3. Measure the height of the headlight centers from the floor on your car. This will be the distance h on the screen.
4. Set the headlight beam adjuster on the instrument panel to the position corresponding to the load of the vehicle with one driver.
5. Turn on the low beam.
6. It is recommended to adjust the direction of the light spot for each headlight separately. Cover the second headlight with opaque material during adjustment.
7. Open the hood and, by turning the adjusting screw 1, adjust the position of the light spot on the screen for each headlight vertically or, by turning the screw 2, horizontally if the location of the light spots does not correspond to the figure.
8. The headlights are considered adjusted when the upper boundaries of the left parts of the light spots coincide with line 4, and vertical lines 1 and 2 pass through points E1 and E2 of intersection of the horizontal and inclined sections of the light spots.
If the car is equipped with fog lights, the direction of their light beam must be adjusted only by height. Turn the adjusting screw until the upper edges of the light spots are on line 4 or slightly below it.
