Variable steering concept
Active rear axle steering
The rear axles are electro-hydraulically actively steered depending on the speed
andthesteeringangleofthefrontaxles.5steeringprograms(P)arepreselecta-
ble by push button.

P1 Road steering
The axles 1 and 2 are mechanically steered by
thesteeringwheel.Theaxle3,4,5and6are
actively steered depending on the speed and
onthesteeringangleofthefrontaxle.From
30km/htheaxles3and4willbeadjustedto
straightdrivingandxed.From60km/h
theaxles5and6arealsoadjustedto
straight driving and fixed.
P2 All-wheel steering
Theaxles3,4,5and6areturnedbythe
steering wheel depending on the steering
angle of the front axle to provide for the
smallest turning radius.
P3 Crab steering
Theaxles3,4,5and6areturnedbythe
steering wheel to the same direction as
the steering position of axle 1 and 2.
P4 Reduced swing out
Theaxles3,4,5and6areturnedde-
pending on the wheel turn of the front
axlestominimizethebackswingofthe
rear of the chassis.
P5 Independent rear axle steering
The axles 1 and 2 are steered by the
steeringwheel,theaxles3,4,5and6
are steered by push buttons indepen-
dently from the steering angle of the
axles 1 and 2.
