If you want to lock axles manually, make
sure that the steering axle is in a straight
position and close the valve (1) or turn
the button to the off position.
The locking valve will be positioned to-

is minimized and a more balanced load
distribution on the tractor can be pro-

The axle lifting function is controlled au-

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.

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
