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 major assembly wear
depend on regular maintenance. Regular mainte‐
nance 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 (

page 388).
Driving resistance
The principle forms of driving resistance are
incline, rolling and aerodynamic resistance. Driv‐
ing resistance changes depending on, for exam‐
ple, vehicle weight and vehicle speed. Remember
that driving resistance increases with vehicle
speed.
Rolling resistance
Rolling resistance and therefore fuel consumption
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
(

page 375)
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 (
/
page 227) and the data on
the vehicle identification plate (
/
page 384).
R
road and weather conditions, e.g. wet or soft
road surfaces (snow or rain) increase fuel
consumption
Aerodynamics
Air turbulence increases aerodynamic resistance
and therefore fuel consumption. Air turbulence
occurs in particular on additionally installed
equipment, e.g. additional headlamps.
Set the wind deflector to the correct height of the
add-on equipment/semitrailer (
/
page 297).
With open loads, arrange the load so that there
are no gaps.
Cover the load with a tarpaulin and lash down all
tarpaulins on the tractor/trailer combination
securely.
Fuel-saving driving styles
+
ENVIRONMENTAL NOTE
When the air conditioning system or the auto‐
matic climate control is switched on, fuel con‐
sumption will increase.
#
Switch the function on only where nec‐
essary.
The
ECO support
menu item in the
Status
menu
supports you in optimising your driving style and
developing a fuel-saving driving style.
You can keep fuel consumption at low levels by
adopting the following driving style:
R
leave PPC switched on
R
do not depress the accelerator when starting
the engine
R
avoid frequent cold starts
R
do not warm up the engine while stationary
R
switch off the engine when waiting in station‐
ary traffic
R
avoid frequent and heavy acceleration
R
avoid adaptive braking by driving with fore‐
sight
R
drive in an even and considered manner
R
use cruise control (
/
page 236) and the dis‐
tance control assistant driving systems
(
/
page 238).
R
maintain an economical engine speed (green
area of the rev counter) (
/
page 116)
R
avoid speed peaks
R
avoid frequent speed changes, in particular at
high speeds
R
whenever possible, drive using the automatic
drive program
R
shift gears according to requirements
R
avoid frequent gear changes
