Protection of the environment
General notes
H
Environmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
Our objectives are to use the natural resour-
ces which form the basis of our existence on
this planet sparingly and in a manner which
takes the requirements of both nature and
humanity into consideration.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally-responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tyre wear depend on
the following factors:
R operating conditions of your vehicle
R your personal driving style
You can influence both factors. Therefore,
please bear the following in mind:
Operating conditions:
R avoid short trips, as these increase fuel
consumption.
R observe the correct tyre pressure.
R do not carry any unnecessary weight in the
vehicle.
R remove the roof rack once you no longer
need it.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R all maintenance work should be carried out
at a qualified specialist workshop.
Personal driving style:
R do not depress the accelerator pedal when
starting the engine.
R do not warm up the engine when the vehicle
is stationary.
R drive carefully and maintain a safe distance
from the vehicle in front.
R avoid frequent, sudden acceleration and
braking. R
change gear in good time and use each gear
only up to Ôof its maximum engine speed.
R switch off the engine in stationary traffic.
R monitor the vehicle's fuel consumption. Returning an end-of-life vehicle
EU countries only:
Mercedes-Benz will take back your old vehicle to dispose of it in an environmentally-respon-sible manner in accordance with the Euro-
pean Union (EU) End of Life Vehicles Direc-
tive.
There is a network of return points and dis-
assembly plants available. You can return
your vehicle to these plants free of charge.
This makes a valuable contribution to the
recycling process and the conservation of
resources.
For further information on recycling old vehi- cles, recovery and the terms of the policy,
visit the Mercedes-Benz homepage. Genuine Mercedes-Benz parts

Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.
! Airbags and seat belt tensioners, as well
as control units and sensors for these
restraint systems, may be installed in the
following areas of your vehicle:

General notes You can change gear yourself using the steer-
ing wheel gearshift paddles. The transmission
must be in position D.
Depending on which gearshift paddle is
pulled, the automatic transmission immedi-
ately shifts into the next gear up or down, if
permitted.
Mercedes-AMG vehicles: to use manual
shifting, you have two options:
R temporary setting
R permanent setting
If you activate manual gearshifting, the mul-
tifunction display will show the current gear
instead of transmission position D.
If manual gearshifting is deactivated, the
gears will be selected automatically.
Temporary setting X
To activate: shift the DIRECT SELECT lever
to position D.
X Pull steering wheel gearshift paddle :
or ;.
Temporary setting will be active for a certain
amount of time. Under certain conditions the
minimum amount of time is extended, e.g. in the case of lateral acceleration, during an
overrun phase or when driving on steep ter-
rain.
X To deactivate: pull steering wheel gear-
shift paddle ;and hold it in place.
or X Use the DIRECT SELECT lever to shift the
transmission position.
or X All vehicles (except Mercedes-AMG vehi-
cles): use the DYNAMIC SELECT button to

Drive sensibly – save fuel
Observe the following tips to save fuel:
R The tyres should always be inflated to the
recommended tyre pressure.
R Remove unnecessary loads.
R Remove roof racks when they are not nee-
ded.
R Warm up the engine at low engine speeds.
R Avoid frequent acceleration or braking.
R Have all maintenance work carried out as
indicated by the service intervals in the
Service Booklet or by the service interval
display.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic, on
short journeys and in hilly terrain. ECO display
The ECO display shows you how economical
your driving style is. The ECO display assists
you in achieving the most economical driving
style for the selected settings and prevailing
conditions. Consumption can be significantly influenced by your driving style. :
Acceleration
; Coasting
= Constant
? Additional range achieved
Range ?is shown under Bonus fr. start Bonus fr. start
and represents the additional range achieved
since the beginning of the journey as a result of an adapted driving style.
If the fuel level has dropped into the reserve
range, the Reserve fuel Reserve fuel message is shown
in the multifunction display instead of
range ?. In addition, the 8warning lamp in the instrument cluster lights up
(Y
page 301).
The ECO display consists of three sections,
with an inner and outer area. The sections
correspond to the following three categories: :
Acceleration
(evaluation of all
acceleration processes):
R the outer area fills up and the
inner area lights up green: mod-
erate acceleration, especially at
higher speeds
R the outer area empties and the
inner area is grey: sporty accel-
eration ;
Coasting
(evaluation of all decel-
eration processes):
R the outer area fills up and the
inner area lights up green: antic-
ipatory driving, keeping your dis- tance and early release of the
accelerator. The vehicle can
coast without use of the brakes.
R the outer area empties and the
inner area is grey: frequent heavy
braking =
Constant
(continuous evaluation
over the entire journey):
R the outer area fills up and the
inner area lights up green: con-
stant speed and avoidance of
unnecessary acceleration and
deceleration
R the outer area empties and the
inner area is grey: fluctuations in
speed The three inner areas display the current driv-
ing style and light up green as a result of a
particularly economical driving style.
Depending on the driving situation, up to two
areas may light up simultaneously.
At the beginning of the journey, the three
outer areas are empty and fill up as a result of 188

economical driving. A higher level indicates a
more economical driving style. If the three
outer areas are completely filled at the same
time, the driver has adopted the most eco-
nomical driving style for the selected settings and prevailing conditions. The ECO display
border lights up.
The ECO display does not indicate the actual
fuel consumption. The additionally achieved
range displayed under Bonus fr. start
Bonus fr. start
does not indicate a fixed consumption reduc- tion.
In addition to driving style, the actual con-
sumption is affected by other factors, such
as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers
These factors are not included in the ECO dis-
play.
An economical driving style involves driving at a moderate engine speed.
To achieve a higher value in the categories
"Acceleration" and "Constant":
R observe the gearshift recommendation
R drive the vehicle in drive program Cor E
(vehicles with DYNAMIC SELECT button).
On long journeys at a constant speed, e.g. on
the motorway, only the outer area for "con-
stant" will change.
The ECO display summarises the driving style from the start of the journey to its completion.
Therefore, there are more marked changes in the outer areas at the start of a journey. Dur-
ing a prolonged driving time, these changes
are smaller. For more marked changes, per-
form a manual reset (Y page 243).
Further information on the ECO display
(Y page 242). Brakes
Important safety notes G
WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients Change into a lower gear in good time on long
and steep downhill gradients. Take particular note of this when driving a laden vehicle and
when towing a trailer. For vehicles with auto-
matic transmission, you need to activate
manual gearshifting (Y page 177).
This also applies if you have activated cruise
control, SPEEDTRONIC or DISTRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
vehicle speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly.
Briefly depressing the accelerator pedal on
downhill gradients while the manual drive
program Mis temporarily activated (vehicles
with automatic transmission): the automatic
transmission may switch back to the last
active automatic drive program Eor S. The
automatic transmission may shift to a higher
gear. This can reduce the engine's braking
effect.
Heavy and light loads G
WARNING
The braking system can overheat if you leave your foot on the brake pedal while driving.
This increases the braking distance and could
even cause the braking system to fail. There is
a risk of an accident. Driving tips

Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with a load, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components. This could result in dam- age to the tyres or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tyres,
wheels or accessories other than those tes-
ted and approved.
Further information about wheels, tyres
and approved combinations can be
obtained from any qualified specialist
workshop.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not fit
used tyres if you have no information about their previous usage.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as a result of driving over obstacles
increases.
Overview of abbreviations used in the follow- ing tyre tables:
R BA: both axles
R FA: front axle
R RA: rear axle
The recommended tyre pressures can be
found in the tyre pressure table on the fuel
filler flap. Further information on tyre pres-
sure (Y page 362). Check tyre pressures reg-
ularly and only when the tyres are cold. Notes on the vehicle equipment – always fit
the vehicle:
R with tyres of the same size across an axle
(left/right)
R with the same type of tyres at a given time
(summer tyres, winter tyres, MOExtended
tyres)
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
Observe the "MOExtended tyres (tyres with
run-flat characteristics)" section
(Y page 340).
Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It is
therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteris-
tics, e.g. winter tyres. A TIREFIT kit can be
obtained from a qualified specialist work-
shop.
