Headlamp, Adjusting, General Information
- The following test and adjustment description applies to all countries.
- However, national guidelines or regulations of the country must be observed.
Testing and Adjusting Conditions
- Tire pressure is OK.
- The headlamp glass must be clean and dry.
- The headlamp glass must not be damaged.
- Headlamp reflectors and bulbs are OK.
- The electro-mechanical parking brake must not be engaged so the vehicle is not under tension.
- The vehicle and headlamp adjusting unit must be on a level surface.
- Keep all doors and the rear lid closed for the duration of the testing/adjusting procedure.
- The headlamp must cool down to room temperature -- open the hood and touch the housing cover on the back of the headlamp.
- The vehicle must be under load.
Vehicle load on driver seat in otherwise unloaded vehicle (curb weight).
- One person or 75 kg.
The curb weight is the weight of the operational vehicle with a completely full fuel tank, including the weight of all equipment carried while in operation.
- Fuel tank, washer fluid reservoir, and SCR tank: at least 90% full.
- Equipment: for example, spare tire, tools, vehicle jack, fire extinguisher, etc.
If the fuel tank is not at least 90% full, the load must be prepared as follows.
-- Check the fuel tank fill level in the instrument cluster fuel gauge and compare it with the following table. Place additional weight in the luggage compartment, if necessary.
| Fuel Gauge | Additional Weight (54 liter tank PR number 0M1 / 58 (15.3 gallons) liter tank PR number 0M2) | Additional Weight (40 (10.5 gallons) liter tank PR number 0M0) | Additional Weight (A4 g-tron, Natural Gas Tank PR Number 0M3) |
|---|---|---|---|
| Empty | 44 kg (97 lbs) | 32 kg (73 lbs) | 20 kg (44 lbs) |
| 1/4 | 33 kg (73 lbs) | 24 kg (53 lbs) | 15 kg (33 lbs) |
| 1/2 | 22 kg (49 lbs) | 16 kg (35 lbs) | 10 kg (22 lbs) |
| 3/4 | 11 kg (24 lbs) | 8 kg (18 lbs) | 5 kg (11 lbs) |
| full | 0 | 0 | 0 |
| Example: If the fuel tank (54 liter (14.2 gallons) tank PR number 0M1) is halfway filled an additional weight of 22 kg (49 lbs) must be placed in the luggage compartment. | |||
TIP:
Use containers filled with water as additional weight (a five liter container filled with water weighs approximately 5 kg (11 lbs)).
Continuation for All Vehicles:
- The angle dimension -arrow- is stamped for ECE countries on the upper edge of the headlamp -1- in "%".
- The angle dimension for the North American market version (before Product Improvement) is generally 0.0% based on the "VOR" adjustment instructions.
- The angle dimension for the North American market version (from Product Improvement) is generally 0.7% based on the "VOL" adjustment instructions.
TIP:
The percentage value is based on a 10 meter projection distance. An angle dimension of 1.0%, for example, converts to 10 cm.
-- If equipped, pry off the cover -1- in direction of -arrows-.
