5.4 Off-road driving
This section describes adjustments, connections and procedures for adapt-
ing the vehicle handling to off-road conditions.
Adjustments to
the transmission If you drive continuously for short periods of time with different loads or on
a slippery surface, the transmission may switch gears too late or too early.
In this event you can make the following adjustments:
– Shift to a lower starting gear;
à
p. 5 - 28.
– Step on the accelerator as far as it will go when starting – starting mode
for load on.
– Select the “Manual” operating mode. This will allow you to drive carefully
and promptly shift gears;
à

Connections If the adjustments to the transmission are insufficient on their own, you can
additionally connect the following one after the other:
