the same time move the gear shift lever to A
Limp home
is activated
3 Move the gear shift lever to M
4 Select gear using the +/– button on the gear shift

is selected, it is not possible to drive
if the gear shift lever is in position A. Only gears 1, 3
and 5 forwards and 1 reverse can be used. Gear
shifting is only possible when the truck is stationary.

when you change between the M and R modes.

Fuel economy driving
I-Shift
is optimised for the best fuel consumption in
relation to the truck's situation. For the best fuel
savings, choose to drive in A mode as much as
possible. Only choose the M mode when the driving
conditions require manual intervention.
I-Roll
During normal driving, the gear shift lever should be
in the A position and the auxiliary brake in the A
position in order for
I-Roll
to be accessible. Use
I-Roll
as much as possible, e.g. on slight downhill slopes.
Set the cruise control's speed slightly lower and
instead increase the overspeed. This gives more
