Hydromove
The hydromove drive function allows you to
drive down inclines slowly, in a controlled man-
ner.
You can move the vehicle forwards or back-
wards on an uphill gradient using only the accel-
erator. This is particularly of benefit when oper-
ating the vehicle with a trailer containing a heavy
load as you do not need to change gear or
depress the service brake. To do this you must
select a pulling-away gear for the direction
opposite to your desired direction of travel.
The drive function is always automatically acti-
vated when you start the engine. The drive func-
tion is only automatically deactivated in the off-
road gearshift program.
Activate or deactivate the hydromove drive
function via the
Systems
menu window in the

If power is provided, the vehicle will continue
to drive up the incline.
Manoeuvring mode
General notes
On vehicles with a hydrodynamic clutch,
manoeuvring mode allows you to manoeuvre
more precisely. You can also pull away using
manoeuvring mode and deactivate manoeu-
vring mode to continue driving. The starting
power is higher in the power, heavy and off-
road gearshift programs.
In manoeuvring mode, the vehicle starts up as
soon as you release the service brake – auto-
matic forward crawling.
Manoeuvring mode does not deactivate auto-
matically.
When manoeuvring mode is active, the trans-
mission does not change gear automatically. It
is possible to deactivate manoeuvring mode by
depressing the accelerator pedal beyond the
point of resistance (kickdown).
Activating manoeuvring mode
X Stop the vehicle, leaving the engine running.
X
Depress the brake pedal.
