General notes
Notes on trailer/semitrailer coupling
The trailer or semitrailer coupling is one of the
vehicle components with particular importance
for road safety. Please comply with the manu-
facturer's operating, care and maintenance
instructions.
If you fit a trailer coupling, observe the body/
equipment mounting directives.
If your semitrailer tractor vehicle is equipped
with a coupling ramp/coupling aid, the inclina-
tion angle specified in ISO 1726 cannot be

or let it come into

guaranteed for all semitrailer coupling dimen-
sions. Note that the clearance between the
semitrailer tractor vehicle and the semitrailer
may be restricted, and you should adapt your
driving style accordingly.
Driving tips for trailers/semitrailers
! Always observe the following safety
instructions for driving with trailers and
semitrailers:
only attach a trailer/semitrailer at an
R
appropriate trailer/semitrailer coupling.
ensure there is adequate clearance
R
between the trailer/semitrailer and the
tractor vehicle.
if the vehicle is being driven without a
R
load, only a trailer without a load may be
coupled up.
do not exceed the permissible axle loads.
R
adhere to a minimum front axle load. This
R
ensures adequate steerability for the trac-
tor vehicle.
Minimum front axle load — tractor vehicle:
25% = three-axle vehicle
30% = two-axle vehicle (trailer lighter or
as heavy as the tractor vehicle)
35% = two-axle vehicle (trailer heavier
than the tractor vehicle)
Articulation angles
If the articulation angle is exceeded, the
!
tractor vehicle and the trailer/semitrailer
can be damaged.
The articulation angles are dependent on the
particular tractor vehicle and trailer/semi-
trailer and are influenced by:
wheelbase
R
height of add-on equipment
R
overhang
R
distance from the tractor vehicle to the
R
