Halogen Headlamp, Adjusting
Special Tools And Workshop Equipment Required
- Headlamp Adjusting Unit :VAS209B
- Headlamp Adjusting Unit :VAS621001
Checking and Adjusting Conditions
- Tire pressure is OK.
- The headlamp lens must be clean and dry.
- The headlamp lens may not be damaged.
- Headlamp reflectors and bulbs are OK.
- Vehicle load must be created.
Vehicle load on driver's seat in otherwise unloaded vehicle (curb weight).
- One person or 75 kg (165.34 lbs).
The curb weight is the weight of the operational vehicle with completely full fuel tank, including the weight of all equipment carried in operation.
- Fuel tank: at least 90% full.
- Equipment: for example, spare wheel, tools, vehicle jack, fire extinguisher, etc.
If the fuel tank is not at least 90% full, the load must be created as follows.
-- Check fuel tank fill lever in instrument cluster tank gauge and compare with the following table. Place additional weight in the luggage compartment, if necessary.
| Fuel Gauge | Additional Weight |
|---|---|
| 1/4 | 38 kg (83.77 lbs) |
| 1/2 | 25 kg (55.11 lbs) |
| 3/4 | 13 kg (28.66 lbs) |
| full | 0 |
| Example: if the fuel tank is half full, an additional 25 kg (55.11 lbs) must be placed in the luggage compartment. | |
Use fuel containers filled with water as additional weight (a five liter fuel container filled with water weighs five kg (1.32 gallons).
- Roll the vehicle several yards or move it back and forth several times to seat the springs.
- The electromechanical parking brake must not be engaged so vehicle is not under stress.
- The vehicle and headlamp adjusting unit must be on a level surface.
- The headlamp adjusting unit must be aligned to the vehicle. To do this, slide the headlamp adjusting unit a specified distance of centered in front of the vehicle and aligned to the vehicle front. Refer to Headlamp Adjusting Owner's Manual.
- Slide the headlamp adjusting unit in front of the corresponding headlamp and check the alignment again.
- The angle dimension is set on the headlamp adjusting unit. Refer to the Headlamp Adjusting Unit Operating Instructions.
- The angle dimension -arrow- is stamped for ECE countries on the upper edge of the headlamp -1- in "%".
- The standard angle dimension for the USA is 0.7%.
The percentage indicator is based on a 10 meter projection distance. At an angle dimension of 1.0%, for example, converts to 10 cm.
PRELIMINARY WORK
-- Turn the headlamp switch to "low beam" - not "Auto".
-- Set the range position thumbwheel to the "0" position.
-- Close all the doors and the rear lid and keep them closed for the duration of the testing/adjusting procedure.
Headlamp Adjustment
The image and the following description apply to analog headlamp adjusting units. Pay attention to the Owner's Manual for the digital headlamp adjusting units for example :VAS209B or :VAS621001 . Refer to the Headlamp Adjusting Unit Owner's Manual.
- The horizontal light-dark border must touch the dividing line -1- on the adjusting unit test surface.
- The point -2- between the left horizontal part and the right rising part of the light-dark border must run vertically through the central mark -3-. The bright core of the light beam must be to the right of the vertical.
-- To determine the bend point -2- more easily, cover and uncover the left half of the headlamp (seen in direction of travel) several times. Then check the low beam again.
- After adjusting the low beam according to the instructions, the center of the high beam light beam must be on the central marking -3-.
-- Turn the adjusting screw -3- to adjust laterally.
The side adjustment bolt -3- must be secured with the plugs after the adjustment is made on USA vehicles. Plugs.
-- To adjust the height of the headlamp -1-, set the cut-off line just under the dividing line with the adjustment screw -2-.
-- Then adjust the cut-off line on the dividing line starting from the bottom.
