Check and adjust the headlights on a loaded vehicle (with a full fuel tank, tool kit and spare tire).
1. Pre-check and, if necessary, adjust the air pressure in the tires to the correct level.
2. Position the car perpendicular to a smooth wall (for example, in the garage) at a distance of 3 m. Place a 75 kg load on the driver's seat. Mark the screen on the wall as shown in Figure 10.6. The longitudinal plane of symmetry of the car should pass along line 0 on the screen. Vertical lines 1 and 2 are located at an equal distance from line 0. The distance a between lines 1 and 2 should be equal to the distance between the centers of the low-beam headlights. Rock the car from the side so that the suspension springs self-align.
3. Measure the height of the headlight centers from the ground on your car. This will be the distance h on the screen.
4. Set the headlight range control knob 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 screws, adjust the horizontal position of the light spot on the screen for each headlight...
8. ...and vertically, if the location of the light spots does not correspond to the drawing.
9. 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.
The fog light beam direction can only be adjusted in height. Turn the adjusting screw until the upper edges of the light spots are on line C (figure 10.7) or slightly below it.
