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:
R
your vehicle is equipped with a sensor-moni-
tored semitrailer coupling and
R
the

indicator lamp in the status area of
the on-board computer lights up green
Sensor-monitored semitrailer coupling

event win-
dow is displayed by the on-board computer
when coupling up, you could damage the sen-
sor-monitored semitrailer coupling and the
semitrailer coupling pin. Check the locking
mechanism on the sensor-monitored semi-
trailer coupling.
!
Observe the wear limits specified in the
manufacturer's operating instructions for the:
R
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 semi-
trailer is coupled up and the ignition is
switched on, check the wear limits:
R
on the semitrailer
R
on the sensor-monitored semitrailer cou-
pling
The sensor-monitored semitrailer coupling has
sensors which, during the attaching/detaching
process or once the ignition has been switched
on, perform the following:
R
monitor the semitrailer, the semitrailer cou-
pling pin and the clasp
R
display the status of the locking mechanism
of the sensor-monitored semitrailer coupling
in the display of the on-board computer
If malfunctions or faults occur during coupling/
decoupling, the on-board computer displays a
Indicator lamps in the status area of the on-
board computer and their meaning:
£
red
The semitrailer is not coupled up. The
sensor-monitored semitrailer coupling
is not engaged.
¤
red
The semitrailer is not correctly coupled
up. The sensor-monitored semitrailer
coupling is engaged, however no semi-
trailer can be detected.
¤
green
The semitrailer is correctly coupled up.
Check that the sensor-monitored sem-
itrailer coupling is in good condition and
engaged correctly.
î
red
The sensor monitoring of the semi-
trailer coupling is malfunctioning.
Observe the additional information in
the red event window of the on-board
computer.

WARNING
If there is too much play on the tractor/semi-
trailer combination between the semitrailer
coupling pin and the coupling plate, the sem-
itrailer may break away from the coupling
plate. You could lose the semitrailer as a
result. There is a risk of an accident.
Follow the coupling manufacturer's instruc-
tions.
