- flat horizontal area (preferably near the wall of a house, fence or gate);
- 5m tape measure;
- sheet of cardboard (to cover the second headlight when adjusting).
We perform the work with an assistant.
Recommendation. It is advisable to perform the adjustment in the dark. The car must be in running order (fully fueled and without additional cargo). Since it is not easy to find a suitable surface as a screen, it is easier to use a 1x2 m plywood board with markings applied to it. In this case, it is necessary to prepare a support or stand to install the board vertically.
Screen layout diagram for headlight adjustment:
A - vertical line indicating the location of the low beam lamp of the left headlight;
B — vertical line indicating the location of the low beam lamp of the right headlight;
C - horizontal line indicating the location of the low beam headlights;
D — line indicating the height of the horizontal boundary of the light beams;
O - center line;
l = 1250 mm — distance between the centers of the low beam lamps;
h — distance from the surface of the platform on which the vehicle is installed to the low beam headlights
Sequence of adjustment of light of headlights
1. Place the car on a flat horizontal platform perpendicular to the surface selected as a screen and at a distance of 5 m from it. You can install a sheet of plywood in front of the car, observing the same conditions.
2. Mark the screen according to the drawing.
Note: The necessary measurements can be taken using a tape measure.
3. Check the tire pressure and, if necessary, bring it up to standard (see "Checking tire pressure").
4. Turn the headlight corrector control to the position corresponding to the minimum load of the vehicle ("0").
5. The assistant sits in the driver's seat, after which we vigorously rock the car from the side to adjust the suspension.
6. Turn on the low beam headlights and cover one of the headlights, for example the right one, with a sheet of cardboard.
Note: The operation is shown on the Astra model, on the Zafira model the work is performed in a similar way.
7. Remove the rubber plug from the adjusting bolt 1.
8. Using an 8 mm Allen key, turn the adjusting screw 2 of the left headlight to bring the horizontal boundary of the light beam to line D, and then, by turning the adjusting screw 1, align the break in the boundary of the light beam with line A.
9. Adjust the right headlight in the same way.
If the beam edge is blurred or unclear, this may be caused by a faulty low beam lamp (see "Headlight - bulb replacement"), damage or destruction of the headlight unit (see "Astra headlight unit - removal and installation" or "Headlight unit model Zafira - removal and installation") or a heavily clouded plastic protective cap (see below).
Sequence of adjustment of fog lights
1. Place the car on a flat horizontal platform perpendicular to the surface selected as a screen, at a distance of 5 m from it. You can install a sheet of plywood in front of the car, observing the same conditions.
2. Mark the screen according to the drawing.
Note: The necessary measurements can be taken using a tape measure.
3. Check the tire pressure and bring it up to normal if necessary.
Screen layout diagram for adjusting fog lights:
A - vertical line indicating the location of the left fog lamp;
B - vertical line indicating the location of the right fog lamp;
C - horizontal line indicating the location of the fog lamps;
D — line indicating the height of the horizontal boundary of the light beams;
O - center line;
l = 1040 mm — distance between fog lamps;
h — the distance from the surface of the platform on which the vehicle is installed to the fog lamps.
4. The assistant sits in the driver's seat, after which we vigorously rock the car to self-adjust the suspension.
5. After turning on the fog lights, cover one of them, for example the right one, with a sheet of cardboard.
Note: The operation is shown on the Zafira model, on the Astra model the work is performed in a similar way.
6. Using an 8 mm Allen key, turn the adjusting screw of the left headlight, bringing the horizontal boundary of the light beam to line C.
7. Adjust the right fog light in the same way.
