Mercedes-Benz Actros 2017, Operating Instructions Manual

Page: 312 / 436

Operating conditions
The following operating conditions affect fuel
consumption:
R
topography, e.g. driving on level routes or in
mountainous terrain
R
outside temperature and weather conditions
R
operating conditions, e.g. operation on con-
struction sites, long distance or short dis-
tance driving
R
gross vehicle weight
R
regeneration of the diesel particle filter
When the vehicle is in new condition, the
regeneration of the diesel particle filter is car-
ried out more frequently than at later stages
in the vehicle's operating life as a result of the
teach-in process.
Maintenance
The fuel consumption and assembly wear
depend on regular maintenance. Regular main-
tenance of the vehicle increases road safety and
lowers fuel consumption. Keep to the mainte-
nance intervals. Always have maintenance work
carried out at a qualified specialist workshop.
Fuel type
The fuel grade also affects fuel consumption.
Use of lower fuel grades and/or non-approved
fuel additives will increase fuel consumption.
Ensure that you refuel with the appropriate fuel
grade (
Y
page 422).
Driving resistance
General notes
The principle forms of driving resistance are
incline, rolling and aerodynamic resistance.
Driving resistance changes depending on, for
example, vehicle weight and vehicle speed.
Remember that driving resistance increases
with vehicle speed.
Rolling resistance
Rolling resistance and therefore fuel consump-
tion are affected by the following factors:
R
tyre size and tyre type
R
tyre pressure, e.g. correctly set tyre pressure
reduces fuel consumption
Check the tyre pressure at regular intervals
(
Y
page 405).
R
tyre type, e.g. summer or winter tyres, single
or twin tyres
R
tyre tread and tyre width, e.g. coarse tyre
treads such as those on winter tyres increase
fuel consumption
R
load distribution, e.g. even load distribution
increases not only driving safety, but also tyre
life
Observe the notes on the permissible wheel
and axle loads (
Y
page 266) and the data on
the vehicle identification plate (
Y
page 417).
R
road and weather conditions, e.g. wet or soft
road surfaces (snow or rain) increase fuel
consumption
Aerodynamics
Air turbulence increases aerodynamic resist-
ance and therefore fuel consumption. Air turbu-
lence occurs in particular at additionally instal-
led equipment, e.g. auxiliary headlamps.
R
Set the wind deflector to the correct height of
the add-on equipment/semitrailer
(
Y
page 332).
R
With open loads, arrange the load so that
there are no gaps. Cover the load with a tar-
paulin.
R
Lash down all tarpaulins on the tractor/trailer
combination securely.
Fuel-saving driving styles
H
Environmental note
Only switch on the air-conditioning system
when necessary. Fuel consumption increases
when the air-conditioning system is switched
on.
The
FleetBoard EcoSupport
menu window in
the
à
driving mode menu shows information on
economical driving style (
Y
page 138). The on-
board computer supports you in optimising your
driving style and developing a fuel-saving driving
style.
You can keep fuel consumption at low levels
with your driving style:
R
Leave PPC switched on (
Y
page 282).
R
Do not depress the accelerator when starting
the engine.
R
Avoid frequent cold starts.
