Headlight range adjustment
e - Installation dimension for the headlight beam angle
n% — Cut-off slope
H - The height of the middle of the angle of inclination of the headlights
h — Cut-off line
1. Place the car on a level ground. Adjust tire pressure. On vehicles with ride height control or ADS, the engine should run at medium speed for approximately 30 minutes.
2. Read the adjustment value (%) for the main and additional headlights on the headlight of the car and set it on the scale of the device for checking and adjusting the headlight angle. Slope 1% «n» corresponds to 10 cm installation dimension «e».
3. Install the test and adjustment device on the same axis as the vehicle and make vertical adjustment in accordance with the marks on the reflector.
4. Start the engine and turn on the low beam headlights.
5. Check up operation of a regulator of an angle of an inclination of light of headlights. The light beams of both headlights must move evenly.
6. Set the headlight range control to «0». On models with xenon headlights, remove the additional weights.
7. Check the low beam headlights and, if necessary, adjust it. When adjusting vertically, the edge of the light beam must exactly coincide with the horizontal line (4) device, with horizontal adjustment, the inclined line (5) must come out of the point of intersection of the vertical line (6) with a horizontal line (4). A common reflector unit on Sedan models from 03.94 onwards allows simultaneous adjustment of the headlights and fog lamps.
8. Check the high beam adjustment. The center of the light beam must be at the corresponding center mark (6). In case of deviation, check the installation of the incandescent bulb.
9. Check and adjust the fog lights. The boundary of the light beam must coincide as closely as possible with the horizontal line (4). If necessary, correct its position. On Sedan models, starting from 03.94, check the tight fit of the incandescent bulb.
