SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION

Auto Shifti ng in Road Gears
In Active Road, Auto Shift will make upshifts or
downshifts through gears 9--12 or 13--16. With the
main shift lever moved fully forward, momentarily
depress the Auto Shift button (1), the Active Road
symbol (trailer) will illuminate in the gear display to
confirm engagement.
The transmission will now make automatic shifts
through gears 9 to 12 or 13 to 16 dependant on the
range selected.
By depressing the Auto Shift button twice, Active
Road can be programmed to automatically upshift or
downshift through gears 9 to 16 including the range
change from 12th to 13th gear.

Changing the Shift Point
To suit different applications, the point at which the
transmission makes an automatic gear shift may be
adjusted from the default setting of 20%. Auto Shift
gear changes are related to an increase or decrease
in engine speed which can be set at 5, 10, 15, 20 or
25 percent.
NOTE: For transport operations the shift point will
automatically default to 20% if a lower figure has
been set. If the shift point is set at 25%, it will remain
at that setting.
With the shift point set at 10%, a transmission upshift
will occur every time the engine speed increases by
10%. Consequently, as the engine speed decreases
by the same amount, the transmission will make a
downshift.
It is recommended that during field operations the
shift point is set at a low percentage, and for road
transport applications, set at a higher figure.

To change the shift point, depress and hold the Auto
Shift button for at least one second. The current shift
point figure appears in the Display of Gears and the
’ramp’ symbol (1) begins to flash. Depress the Auto
Shift button repeatedly to scroll through the shift
points.
With the new shift point selected, release the Auto
Shift button and pause for five seconds. The new
setting will be memorised and the display will return
to normal.
IMPORTANT: At key--off (engine stop), electronic
programme settings made during tractor operation
are transferred from the operating memory to the
main memory. To provide sufficient time for the data
to transfer, allow a minimum of five seconds delay
before turning the key on again.
