Calculating axle loads:
„
Multiply the distance between storage compartment and front axle (A) with
the weight of the load in the storage compartment (G) and divide the result
by the wheelbase (R). The result is the weight of the load in the storage
compartment on the rear axle. Make a note of this weight and of the storage
compartment.
„
In a second step, subtract the weight in the storage compartment (G) from
the weight calculated beforehand. If the result is a
positive value
(example 1), this means that the load on the front axle is reduced by this
value. If the result is a negative value (example 2), this means that the load
on the front axle is increased . Make a note of this value, too.
„
Calculate all storage compartments of the vehicle in the same way.
„
In a last step, add all weights calculated for the rear axle to the rear axle
load and add (or subtract) all weights calculated for the front axle to (from)
the front axle load.
How to determine rear axle load and front axle load is described in
section 3.3.2.
If the calculated value exceeds the permissible axle load, the load must be dis-
tributed in a different way.
If the load on the front axle is too low, the grip of the tyres on the road is
reduced (traction). This applies in particular to vehicles with front wheel drive.
In this case, the load must be redistributed, too.
3.3.4 Roof rail and ladder (special equipment)
Example 1 Example 2
Example calculation Distance to the front axle A (A1) 450 (cm) (A2) 250 (cm)
Weight in the storage compartment G x 100 (kg) x 50 (kg)
Wheelbase of the vehicle R ÷ 325 (cm) ÷ 325 (cm)
Load on the rear axle
(add to the axle load) 138.5 (kg) 38.5 (kg)
Weight in the storage compartment - 100 (kg) - 50 (kg)
Load relief to the front axle
(subtract from the axle load) 38.5 (kg)
Load on the front axle
(add to the axle load) -11.5 (kg)
X
Access the roof only when a roof rail has been fitted.
X
Take care when stepping onto the ladder. There is danger of slipping
when the ladder is moist or icy.

Take care when stepping onto the roof. There is danger of slipping when
the roof is moist or icy.
X
Do not overload the roof. Road behaviour and brake reaction deteriorate
as the roof load increases.
Z
If the vehicle is equipped with a roof rail, load racks can be mounted on the
roof rail for roof loads (e.g. for surfboards, rubber boats or light canoes).
Special girder systems are available as accessory. The authorised dealer
or service centre will be happy to advise you.
Z
The maximum permissible roof load is 200 kg.
