Actions With Gearbox Malfunction; Fuel Economy Driving - Volvo FM Handbook

248 I-Shift

Actions with gearbox malfunction

If the gearbox has a fault which means you cannot
drive the truck, activate the Limp home function to be
able to drive the shortest way home or to a workshop.
Activate Limp home as follows:
1 Move the gear shift lever to N
2 Keep L pressed in on the gear shifter cover and at
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
lever
When Limp home 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.
The L button does not need to be pressed in again
when you change between the M and R modes.
The Limp home function is disengaged when the
ignition is turned off.

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
Note!
The Limp home function should
only be used for short distances.
