Test Requirements
Checking and Adjusting Conditions:
- Tire pressure OK
- Lenses must not be damaged or dirty.
- Reflectors and bulbs OK
- Vehicle must be properly loaded.
- Move vehicle back and forth for 1 meter (3 to 4 feet) or bounce front and rear of vehicle several times up and down to settle suspension.
- Both the vehicle and the headlamp adjusting unit must be standing on flat ground → Operating Instructions for headlamp adjusting units VAS 5046, VAS 5047, VAS 5208A, VAS 5209A and VAS 5209B.
- Vehicle and headlamp adjuster must be aligned.
- Inclination dimension must be set.
- The DTC memory must be erased.
Later headlamp adjustment is not permitted on North America vehicles. These vehicles have a anti-twist mechanism.
In the trim above the headlamp, inclination measurements are stamped in "%". Headlamps must be adjusted according to this information. Percentage information is based on a projection distance of 10 meters. For example: inclination of 1.0 % converts to approximately 10 cm.
Adjust the headlamps to a 0.7% angle dimension on North America vehicles.
Load: Vehicle must be loaded with one person on the driver seat, weighing 200 lbs (75 kg), otherwise vehicle must be empty (curb weight).
The curb weight is the weight of the vehicle ready for operation with completely filled fuel tank (at least 90%), including the weight of all equipment items carried for operation (e.g. spare wheel, tool, vehicle jack, fire extinguisher etc.).
If the fuel tank is not at least 90% full, adjust weight as follows:
-- Read fuel level from fuel gauge. Calculate additional weight needed using the following table. Place extra weight in luggage compartment.
Tank Filling Table
| Fuel gauge level | Additional weight in luggage compartment in lbs (kg) |
|---|---|
| Up to 1/4 | 66 (30) |
| Up to 1/2 | 44 (20) |
| Up to 3/4 | 22 (10) |
| full | 0 |
Example:
If the fuel tank is half full, place an additional 66 lbs (25 kg) or 33 lbs (15 kg) weight in the luggage compartment.
For the additional weight, use a suitable container filled with water or gravel (a 5 liter fuel can filled with water weighs approximately 11 lbs (5 kg).
Make sure the there are kg markings on the container and that it cannot be opened.
Place a cloth on the luggage compartment floor to protect it from getting dirty.
