Manual regeneration will only start when the fol‐
lowing conditions have been met:
the engine oil and coolant temperature is suf‐
R
ficiently high.

the AdBlue
is not frozen.

The engine speed is increased and the engine
noise may change during regeneration.
When regeneration is complete, the indicator
lamp É in the instrument cluster goes out and
the engine speed decreases to the idle speed.
Regeneration is cancelled automatically in the fol‐
lowing cases:
the multifunction lever is set in position h or

k.
The parking brake is released.
R
regeneration lockout is activated.
R
power take-off is activated.

If at low outside temperatures, the on-board
computer prompts you to perform manual
regeneration, start regeneration before park‐
ing the vehicle. If the vehicle is parked with‐
out performing regeneration, manual regen‐
eration can only be started after the engine
warm-up phase.
Under the following conditions, manual
regeneration can only be started after a
thawing time of up to 60 minutes:

AdBlue
is frozen.
R
the vehicle was parked without perform‐
R
ing regeneration.
Fuel consumption
Fuel consumption depends on the following fac‐
tors:
the vehicle version
R
the operating conditions
R
maintenance
R
the fuel type in use
R
driving resistance
R
your driving style
R
For these reasons, it is not possible to provide
precise information on fuel consumption for each
individual vehicle.
Information and instructions on how to keep fuel
consumption low can be found in the section on
"Economic and environmentally aware driving"
(
page 274).

AdBlue
consumption is up to 5.5% of the fuel
consumption.
Engine oil consumption
On an engine that has been run in, oil consump‐
tion can amount to up to 0.2% of the actual fuel
consumption.
The oil consumption may exceed this value if you
operate your vehicle under arduous operating
conditions or if the mileage is high.
Limit speed
& WARNING Tractor/trailer combination
swerving due to increased speed
If the tractor/trailer combination swerves,
you could lose control of the tractor/trailer
combination.
The tractor/trailer combination may even
overturn.
On no account should you attempt to
#
straighten up the tractor/trailer combi‐
nation by increasing the speed.
Reduce speed and do not counter-steer.
#
If necessary, apply the brakes.
#
On vehicles with a limit speed, the maximum
speed of the vehicle is limited according to
national legal requirements, e.g. to approximately
90 km/h. The engine speed is automatically limi‐
ted when the restricted top speed is reached.
Take this into account when overtaking.
