DANGER
Risk of accidents due to non-functional
EBS!
If the EBS plug connection function is not
established, the EBS of the vehicle and
the automatic load-dependent brake
power regulation cannot work. The vehicle
is overbraked and the wheels may lock.
Serious traffic accidents could occur. Driv-
ing without the EBS plug connection is
prohibited by law.
► Only drive with an approved, connec-
ted and functioning EBS plug connec-
tion.
► Always connect the EBS plug connec-
tions between the tractor unit and the
trailer.
► Verify the EBS plug connection via a
system check (the magnetic valves in
the EBS modulator are audibly and
briefly activated and deactivated for 2
seconds after “ignition on”)
► Only use plug connections that com-
ply with the regulations.
► Have the fault immediately repaired
by the nearest contract workshop.

WARNING
Risk of accident due to unharmonised
brake power tuning!
Unharmonised brake power between the
tractor unit and trailer may lead to insuffi-
cient or excessive trailer braking values.
This can cause wear and accidents.
► Monitor the automatic coupling force
control to harmonize the brake power.
► Pay attention to the sticker on the
trailer.
