Driving tips for trailers/semitrailers
General notes
! Always observe the following safety instruc-
tions for driving with trailers and semitrailers:
R
only attach a trailer/semitrailer at an
appropriate trailer/semitrailer coupling.
R
ensure there is adequate clearance
between the trailer/semitrailer and the
tractor vehicle.
R
if the vehicle is being driven without a load,
only a trailer without a load may be coupled
up.
R
do not exceed the permissible axle loads.
R
adhere to a minimum front axle load. This
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)
i On vehicles with pneumatic suspension and
axle load indicators, the current axle loads
can be called up on the on-board computer
(

! If you drive with more than two trailers/
semitrailers, you must switch off Stability
Control Assist. Otherwise, malfunctions or
faults can occur as a result.
Deactivating/activating Stability Control Assist

Articulation angles
! If the articulation angle is exceeded, the
tractor vehicle and the trailer/semitrailer can
be damaged.
