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).

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.

Fuel gauge	Additional weight in kg
1/4	45
1/2	30
3/4	15
full	0
Example: if the fuel tank is half full, an additional 30 kg must be placed in the luggage compartment.

NOTE:

Use fuel containers filled with water as additional weight (a five liter fuel container filled with water weighs five kg).

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. Refer to the Headlamp Adjusting Unit Instructions.
