• Shift the speed range up by pressing the speed range sel button.
You can change the speed range upwards by more than one step at a time,
directly from A to D for example. A pop-up window indicating the speed range
change appears on the display until the requested speed range has
engaged.
• Shift the speed range down by pressing the speed range selection - button.
You can change the speed range downwards by more than one step at a
time, directly from D to A for example. The change is implemented provided
that the driving speed at the time of the request is within the defined limits for
speed range changing. The request does not stay in the memory but has to
be repeated when the driving speed has dropped below the limit. The driving
speed limits for changing speed ranges given in the following table are
approximate values and depend on the tire size:
Speed range change Maximum driving speed (40 km/h
models)
Maximum driving speed (50 km/h
models)
Changing from D to C 17.5 km/h 22 km/h
Changing from C to B 9 km/h 11 km/h
Changing from B to A 5.5 km/h 7 km/h
A pop-up window indicating the speed range change appears on the display
until the requested gear has engaged.
• Shift speed range between ranges C and D.
You can change between speed ranges C and D without pressing the speed
range selection buttons when speed range C-D shifting automatics is
activated and shifting automatics is in the manual mode.
For example:
• When Powershift 5 of speed range C is engaged and you press the
button for shifting up the Powershift gear, the automatics shift the gear to
the appropriate Powershift gear in speed range D according to the driving
speed and engine speed.
OR
• When Powershift 1 of speed range D is engaged and you press the
button for shifting down the Powershift gear, the automatics shift the gear
to the appropriate Powershift gear in speed range C according to the
driving speed and engine speed.
