Driving Programs; Automatic Gear Changing - Volvo FM Handbook

Powertronic 209

Driving programs

Driving programs E and P are used only for automatic
gear changing when the gear shifter is in position A.
E The economy program gives lower fuel
consumption.
P The power program is used when power has priority
over fuel consumption. Up- and down-changing is
done at higher engine speeds.

Automatic gear changing

Gear changing is completely automatic in position A.
When reversing (R), gear changing is done manually.
If the gear shift lever is moved to M when driving with
the automatic program A changing will be inhibited
and the current gear will remain engaged through the
entire engine operating range.
If, while driving you want to make sure that 1st gear
will be used, e.g. on steep hills or with high rolling
resistance, the gear can be pre-selected. Pre-selection
means that down-changing, when necessary, is done at
an optimum engine speed, without the driver being
aware of it. Down-changing is done when the right
speed has been reached.
To pre-select 1st gear, press once on the minus button
while driving. Pre-selection of 1st can only be done at
speeds below 50 km/h. 1st remains as selected until
the driver presses +. When the speed exceeds 50 km/h,
it returns to automatic selection between 1 and 2 gears.
