The maximum permissible vertical
coupling load 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 trailers. The
vertical coupling load should never
fall below 25 kg.
In the case of trailer loads of 1200 kg
or more, the vertical coupling load
should not be less than 50 kg.
Rear axle load
When the trailer is coupled and the
towing vehicle fully loaded (including
all occupants), the permissible rear
axle load (see identification plate or
vehicle documents) must not be
exceeded.

warning
For vehicles fitted with towing

warning changes upon operation of
the turn signals.
The pitch of the audible warning will
change if a turn signal light on the
trailer or the towing vehicle fails.
