Protection of the environment
Notes

Environmental note
Daimler's declared policy is one of integrated
environmental protection.
The objectives are for the natural resources
which form the basis of our existence on this
planet to be used sparingly and in a manner
which takes the requirements of both nature
and humanity into account.
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. You should
bear the following in mind:
Operating conditions:
R avoid short trips as these increase fuel con-
sumption.
R make sure that the tyre pressures are
always correct.
R do not carry any unnecessary weight.
R keep an eye on the vehicle's fuel consump-
tion.
R remove roof racks once you no longer need
them.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have maintenance work carried out
at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
Personal driving style:
R do not depress the accelerator pedal when
starting the engine.
R do not warm up the engine with the vehicle
stationary. R
drive carefully and maintain a safe distance
from the vehicle in front.
R avoid frequent, sudden acceleration.
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. Returning end-of-life vehicles
Mercedes-Benz will take back your
Mercedes-Benz to dispose of it in an environ-
mentally responsible manner, in accordance
with the European Union (EU) End of Life
Vehicles Directive.
The End of Life Vehicles Directive applies to
vehicles with a gross vehicle weight of up to
3.5 t, in accordance with national regulations.
For several years, Mercedes-Benz has been
meeting all the legal requirements for a
design which allows for recycling and reuse.
There is a network of return points and dis-
assembly plants which can recycle your vehi-
cle in an environmentally responsible man-
ner. The options for recycling vehicles and
parts are constantly being developed and
improved. This means that your Mercedes-
Benz will also continue to meet even the
increased recycling quotas in the future in
good time. You can obtain further information
from your national Mercedes-Benz homepage
or your national hotline number. Vehicle equipment
This Owner's Manual describes all models
and all standard and optional equipment of
your vehicle available at the time of publica-
tion of the Owner's Manual. Country-specific
differences are possible. Please note that
your vehicle may not be equipped with all fea-
tures described. This also applies to safety-
relevant systems and functions. The equip-
ment in your vehicle may therefore differ from
that shown in the descriptions and illustra-
tions. All the systems found in your vehicle Introduction

In the automatic drive program, you can
restrict or derestrict the shift range by using
the steering wheel gearshift paddles or the
selector leve r(Ypage 149).
In the manual drive program, you can change
gear using the steering wheel gearshift pad-
dles or the selector lever (Y page 150).
i You can only change gear with the steer-
ing wheel gearshift paddles when the trans-
mission is in position D. Automatic drive program
Drive program E(drive program Con AMG
vehicles) is characterised by the following:
R comfort-oriented engine and automatic
transmission settings.
R optimal fuel consumption resulting from
the automatic transmission shifting up
sooner.
R the vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully.
R increased sensitivity. This improves driving
stability on slippery road surfaces, for
example.
R the automatic transmission shifting up
sooner .This results in the vehicle being
driven at lower engine speeds and the
wheels being less likely to spin. 148
Automatic transmissionDriving and parking

Drive program
S(or, in the case of AMG vehi-
cles, drive programs Sand S+) is character-
ised by the following:
R sporty engine and automatic transmission
settings
R the vehicle pulling away in first gear
R the automatic transmission shifting up
later
R as a resul tofthe later automatic transmis-
sion shift points, the fuel consumption pos-
sibly being higher Shift ranges
Introduction When the automatic transmission is in posi-
tion D, it is possible to restrict or derestrict
the shift range (Y page 149).
The shift range selected is shown in the mul-
tifunction display. The automatic transmis-
sion shifts only as far as the selected gear. Driving situations

Restricting the shift range
X
Press the selector lever to the left towards
D–.
or X
Pull the left-hand steering wheel gearshift
paddle.
The automatic transmission shifts down
one gear and restricts the shift range to the
relevant gear.
i If the engine exceeds the maximum
engine speed when shifting down, the auto-
matic transmission protects against engine
damage by not shifting down.
i If the maximum engine speed for the shift
range is reached and you continue to accel-
erate, the automatic transmission shifts up
in order to prevent the engine from over-
revving, even if the shift range is restricted.

WARNING
Do not use petrol to refuel vehicles with a die-
sel engine. Do not mix diesel with petrol. This
would result in damage to the fuel system and
engine, which could lead to a vehicle fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Even small
amounts of the wrong fuel result in damage
to the fuel system and the engine.
! Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel .Other-
wise, the fuel will ente rthe fuel lines. Notify
a qualified specialist workshop and have
the fuel tank and fuel lines drained com-
pletely. Petrol (EN 228, DIN 51626)
Fuel grade !
Only refuel using unleaded premium-
grade petrol with at least
95 RON/85 MON, which conforms to Euro-
pean standard EN 228 or an equivalent
specification.
! Do not use the following:
R E85 (petrol with 85% ethanol)
R E100 (100% ethanol)
R M15 (petrol with 15% methanol)
R M85 (petrol with 85% methanol)
R M100 (100% methanol)
R Diesel
Do not mix these fuels with petrol, and do
not use any additives. Otherwise, this can
lead to damage to the engine. This does not
include additives for the removal and pre-
vention of residue build-up. Only additives
recommended by Mercedes-Ben zmay be
added to petrol. More informatio nabout
recommended additives can be obtained
from any Mercedes-Benz Service Centre. !
Use a filter when adding fuel from a fuel
can. The fuel lines and/or the diesel injec-
tion system could otherwise be blocked by
particles from the fuel can.
i If the recommended fuel is not available,
but only as a temporary measure, you may
also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption .Avoid driving at full throttle.
In some countries, the fuel grade available
may not be adequate and could cause
deposits to build up. In such cases, and in
consultation with a Mercedes-Benz Service
Centre, the petrol may be mixed with the
additive recommended by Mercedes-Benz
(part number A000989254510). You must
observe the notes and mixing ratios speci-
fied on the container.
For further information on "Fuel", see
(Y page 354).
AMG vehicles and 12-cylinder engines !
Only refuel using super-grad eunleaded
petrol with at least 98 RON/88 MON,
which conforms to European standard EN
228 or equivalent.
You can otherwise impai rengine outpu tor
damage the engine.
i If the recommended fuel is not available
and only as a temporary measure, you may
also use premium-grade unleaded petrol,
95 RON/85 MON. This may reduce engine
performance and increase fuel consump-
tion. Avoid driving at full throttle.
! In emergencies, and only if the recom-
mended fuel is not available, you may also
use standard unleaded petrol, 91 RON/
82.5 MON.
However, using this fuel results in consid-
erably higher petrol consumption and sig-
nificantly reduced engine performance.
Avoid driving at full throttle. Refuelling
