General notes
In the manual drive program, the driver is
responsible for selecting gears.
In particularly difficult driving conditions, switch
to the manual driving program. This will enable
you to avoid any undesired interruptions to the
tractive power that may occur with automatic
gearshifting.
In order to support a fuel-efficient driving style,
the on-board computer displays a gearshift rec-
ommendation in the form of an arrow. Shift up
Z
or down
¬
according to the gearshift recom-
mendation.

suitable engine speeds or at suitable driving
speeds. A warning tone will sound if the engine
speed has not been achieved or if the driving
speed is too high. The gear is not selected. The
