Notes on coupling up
Note on tractor/trailer synchronisation (vehi‐
cles without EBS)

NOTE Increased brake wear
When a trailer or semitrailer is coupled up for
the first time, a tractor/trailer synchronisa‐
tion process should be performed.
Otherwise, increased brake wear may occur.
#
Have tractor/trailer synchronisation
carried out at a qualified specialist
workshop.
Information on the fifth-wheel coupling
&
WARNING Risk of accident due to dam‐
aged or unlocked fifth-wheel coupling
If the fifth-wheel coupling is damaged or not
correctly engaged, you could lose the semi-
trailer.
#
Always check that the fifth-wheel cou‐
pling is free of damage and properly
engaged after coupling up.
Ensure this even if the following conditions have
been met:
R
The vehicle is equipped with a monitored
semitrailer coupling.
R
The green

NOTE Damage to the sensor on the fifth-
wheel kingpin
Note the wear limits in the manufacturer's
operating manual:
R
for the wear ring
R
for the locking hook
R
for the fifth-wheel kingpin
Do not fall below the wear limits. Otherwise,
the sensor on the fifth-wheel kingpin could be
damaged.
#
If a red event window appears several
times on the on-board computer display
when a semitrailer is coupled up and
the ignition is switched on, check the
wear limits on the semitrailer and the
monitored semitrailer coupling:
The monitored semitrailer coupling has sensors
that, during the coupling/uncoupling process or
once the ignition has been switched on, perform
the following functions:
R
monitor the semitrailer, the fifth-wheel king‐
pin and the clasp
R
show the status of the locking mechanism of
the monitored semitrailer coupling on the on-
