Pay attention to swivel angle = during
extreme cornering.
The swivel angle is dependent on the coupling
system on the tractor vehicle and trailer/
semitrailer.
Coupling up
Note on tractor/trailer synchronisation
(vehicles without EBS)
! Tractor/trailer synchronisation should be
carried out when you couple up/attach a
trailer or semitrailer to the tractor vehicle
for the first time. Not doing so could lead to
increased brake wear. Always have trac-
tor/trailer synchronisation carried out at a
qualified specialist workshop.
Information on semitrailer coupling
Important safety notes
G
WARNING
If the semitrailer coupling is damaged or not
correctly engaged, you could lose the semi-
trailer. There is a risk of an accident.
Always check that the semitrailer coupling is
free of damage and properly engaged after
coupling-up.
This should also be checked if:
your vehicle is equipped with a sensor-
R
monitored semitrailer coupling and
the ¤ indicator lamp in the status area
R
of the on-board computer lights up green
Sensor-monitored semitrailer coupling
¤Check semitrailer
! If the red
coupling and open if required
window is displayed by the on-board com-
puter when coupling up, you could damage
the sensor-monitored semitrailer coupling
and the semitrailer coupling pin. Check the
locking mechanism on the sensor-moni-
tored semitrailer coupling.
! Observe the wear limits specified in the
manufacturer's operating instructions for
the:
wear ring
R
locking hook
R
semitrailer coupling pin

Ensure that the parts do not fall below the
wear limits. Otherwise, the sensor on the
semitrailer coupling pin can be damaged.
If a red event window appears several times
in the on-board computer display when a
semitrailer is coupled up and the ignition is
switched on, check the wear limits:
