3.7.2. Axle Lifting
Axle lifting feature is optionally available
in different quantities and location in your
vehicle. Thanks to this feature tire wear
is minimized and a more balanced load
distribution on the tractor can be pro-
vided. The EBS connection must be ac-
tive for the axle lift load to work.
The axle lifting function is controlled au-
tomatically due to the legal regulations.
When the speed limit is exceeded and
the EBS is active, some axles can be
lifted automatically, if the load on the
axles is less than the maximum allow-
able axle load.
The driver may control the axle lifting
manually for the maneuvering aid or
traction help.
For the active traction help
(raising the axle), the vehicle
must be slower than 30 km/h
and the technical capacity of
the axles on the ground must
not exceed 30%.
When the trailer is in a park position, you
may push the brake pedal 3 times and
traction help (axle lifting) might be
activated.
If your vehicle has optional axle lifting
control from the tractor cabinet, it is
possible to manually lower/raise the axle
with a spring loaded button to be in-
stalled in the tractor cabin. For this func-
tion, your tractor must be adjusted
according to the trailer.
It is also possible to activate /deactivate
the axle lifting function with a button on
the trailer. Traction help can be activated
by pressing and holding this button (1)
for less than 5 seconds. If it is pressed
more than 5 seconds, the axle can be
lowered to the ground.
You can also find information about the

vehicle.
If you change the axle lifting
configuration,
your
vehicle
may be out of regulation. For
this reason, the EBS modula-
tor should not be checked or
repair except by authorized
services.
