Driving programs
There are four different driving programs:
• economy
• power or enhanced power for difficult conditions
on poor roads
• braking program
• HD (Heavy Duty)
Economy
When the engine is started, the economy program is
always selected (shown as an E in the display). The
economy program is optimised for best fuel

consumption and is used when driving in normal
conditions.
Power
The power program is engaged/disengaged using the
E/P button (see illustration). When the program is
engaged P/P+ is shown in the display. The power
program prioritises driveability at the sacrifice of
optimal fuel consumption and is used when driving in
hilly terrain and off-road. The power program
generally uses higher engine speeds than economy,
and a lower starting gear is selected.
To save fuel, the gearbox will automatically switch off
the power program when it is no longer required and
returns to the economy program.
Trucks equipped with the enhanced power program P+
has additional functions suited for driving in hilly
terrain and off-road. The program remains active until
the economy program is selected. (The function is
optional.)
Braking program
A special braking program can be engaged (a B is
shown in the display) using the stalk for the auxiliary
brakes. See the "Driver's Manual", section on auxiliary
brakes. (The function is optional.)
