In the case of caravans / trailers with brake,
attach break-away stopping cable to eye
to right of coupling ball bar.

Caravan and trailer loads

The permissible caravan / trailer loads are
vehicle dependent and engine dependent
maximum values which must not be
exceeded. The actual caravan / trailer load
is the difference between the actual gross
weight of the caravan / trailer and the
actual coupling socket load with the
caravan / trailer coupled. When the
caravan / trailer load is being checked,
therefore, only the caravan / trailer wheels
– and not the jockey wheel – must be
standing on the weighing apparatus.
The permissible caravan / trailer loads for
your vehicle are given in the vehicle
documents. Unless otherwise stated, they
are valid for gradients up to max. 12 %.
1)
Observe national regulations.
The permissible caravan / trailer load
should be fully utilised only by drivers who
are adequately experienced in towing
large or heavy caravans / trailers.
The permissible caravan / trailer load
applies up to the specified incline and up to
an altitude of 1000 metres above sea level.
Since engine power decreases as altitude
increases because the air becomes thinner
(thereby reducing climbing ability), the
permissible towing weight also decreases
by 10 % for every 1000 metres of additional
1)
altitude. The towing weight does not have
to be reduced when driving on roads with
slight inclines (less than 8 %, e.g.
motorways).
The actual caravan / trailer load plus the
actual Gross Vehicle Weight must not
exceed the maximum permitted towing
weight. For example, if the permitted Gross
Vehicle Weight is utilised, the caravan /
trailer load must only be used until the
maximum permitted towing weight is
reached. The maximum permitted towing
weight is shown on the identification
plate – see page 212.

Coupling socket load

The coupling socket load is the load
exerted by the caravan / trailer on the
coupling ball. It can be varied by changing
the weight distribution when loading the
caravan / trailer.
The maximum permissible coupling socket
load (50 kg / 110 lbs) is specified on the
towing equipment identification plate
and in the vehicle documents. Always aim
for the maximum load, especially in the
case of heavy caravans / trailers. The
coupling socket load should never fall
below 25 kg / 55 lbs.
When measuring the coupling socket load,
make sure that the drawbar of the loaded
caravan / trailer is at the same height as it
will be when the caravan / trailer is coupled
with the towing vehicle loaded. Particularly
important for caravans / trailers with
tandem axle.
