● Sit with buttocks as far backagainst the backrest as possible.
Adjust the distance between the
seat and the pedals so that legs
are slightly angled when fully
pressing the pedals. Slide the
front passenger seat as far back
as possible.
● Set seat height high enough to have a clear field of vision on all
sides and of all display
instruments. There should be at
least one hand of clearance
between head and the roof
frame. Your thighs should rest
lightly on the seat without
pressing into it.
● Sit with shoulders as far back against the backrest as possible.
Set the backrest rake so that it is possible to easily reach the
steering wheel with arms slightly
bent. Maintain contact between
shoulders and the backrest when
turning the steering wheel. Do
not angle the backrest too far
back. We recommend a
maximum rake of approx. 25°.

a way that the wrist rests on top
of the steering wheel while the
arm is fully extended and
shoulders on the backrest.

fingers wide between the edge of the seat and the hollow of the
