AMG vehicles
! Only refuel using supe runleaded petrol
with at leas t98RON/88 MO Nthat con-
forms to Europea nstandard EN 228 or an
equival ents pecif ication.
Yo uc an otherwise impai rengine outpu tor
damage the engine.
! Premium-grade unleaded petro lwith an
octane ratin gof95R ON/85 MON ma ybe
used as atemporar ymeasur eifthe recom-
mended fuel is not available. This may
reduce engin eperforman ceand increase
fuel consumption .Asmuch as possible,
avoid driving at full throttle.
! Regular unleade dpetrol with an octane
rating of 91 RON/82.5 MON may also be
used as atemporary measure if the recom-
mended fuel is not available.
Doing so result sinnoticeably higher fuel
consumption ,and the engine power output
is noticeably reduced .Avoi dd riving at full
throt tle.
If only regular unleaded petrol with an
octane ratingof91R ON/82.5 MO Nor
lowe risa vailable ,you must have the vehi-
cle adapted to this fuel at aqualified spe-
cialist workshop.
i E10 fuel contains up to 10% bioethanol.
Your vehicle is suitabl efor use with E10
fuel. You can refuel your vehicle using E10
fuel.
Additives
! Operatin gthe engin ewith fuel additives
can cause wear in the fuel high-pressure
pump and contaminate the entire fuel sys-
tem. The repair costs are high. This does
not include additives for the removal and
prevention of residue build-up. Petrol must
only be mixed with additives recommended
by Mercedes-Benz .More information about
recommended additives can be obtained
from any Mercedes-Benz Servic eCentre. One of the major problem
swith low-grade
fuel is the creation of carbon deposits during
the process of burnin gfuel. Mercedes-Benz
recommends that you use fuel brands that
have additives.
If you use fuels without these additives for a
longer period of time, there may be abuild-up
of carbon deposits. Thes ewill form especially
on the inlet valves and in the combustion
chamber.
This could lead to engine runnin gproblems,
e.g.:
R longe rengine warm-up phase
R uneven idle
R engine noise
R misfiring
R los so fpower
In areas where petrol with the required addi-
tives is not available, carbon deposits can
build up. In this case, Mercedes-Benz recom-
mends the use of additives that have been
approved for Mercedes-Benz vehicles; see
http:/ /bevo.mer cedes-benz.com.
The quality of the fuel available in some coun-
tries may not be sufficien t.Residue could
build up as aresult. In such cases, and in
consultation with aMercedes-Ben zService
Cent re,the petrol ma ybemixed with the
additive recommended by Mercedes-Benz
(part no. A000989254510). You must
observe the notes and mixin gratios specified
on the container.
Consult aMercedes-Ben zService Cent reto
view alist of approved products. Observe the
instruc tions for use in the product descrip-
tion.
Do not mix other fuel additives with fuel. This
causes unnecessary cost sand could damage
the engi ne. Service products and capacities

Fuel consumption informa tion H
Environmental note
CO 2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effec t).Y our
vehicle' sCO
2emissions are directly related to
fuel consumption and therefore depend on:
R efficien tuse of the fuel by the engine
R driving style
R other non -technical factors, such as envi-
ronmental influences or road conditions
You can minimise your vehicle's CO 2emis-
sions by driving carefull yand having it serv-
iced regularly.
The vehicle will use more fuel than usua lin
the following situations:
R at very low outside temperatures
R in urban traffic
R on short journeys
R in mountainous terrain
R when towing atrailer
i Only for certain countries :you can find
the curren tconsumption and emission val-
ues of your vehicle in the COC documents
(EU CERTIFICATE OF CONFORMITY). These
documents ar edelivered with your vehicle.
The consumption figures were in each case
based on the curren tlya pplicable version:
R for vehicles that comply with standards
up to and including the EURO 4standard,
in accordance with EU Directive
80/1268/EEC
R for vehicles tha tcompl ywith or exceed
the EUR O5standard ,inaccordanc ewith
Regulatio n(EC )N o. 715/2007
Deviation sfrom thes evalues may occur
under normal operating conditions. AdBlue
®
Important safety notes AdBlue
®
is aw ater-soluble fluid for the
exhaust gas aftertreatmen tofdiesel engines.
It is:
R not poisonous
R colourless and odourless
R not flam mable
When you open the AdBlue ®
container, small
amou ntsofa mmonia vapou rmay be
released.
Ammonia vapours have apungen todour and
are particularly irritatin gtothe skin ,to
mucous membranes and to th eeyes. You may
experie nceab urnin gsensation in your eyes,
nose and throat. Coughing and waterin gof
the eyes are possible.
Do not inhale any ammonia vapours that may
be released. Fill the AdBlue ®
tank only in well-
ventilated areas.
Low outside temperatures AdBlue
®
freezes at atemperatur eofapprox-
imately -11 †. The vehicle is equipped with
an AdBlue ®
preheati ngsyste matt he factory.
Winter operation can therefor ebeguaran-
teed even at temperatures below -11 †.
Additives !
Only use AdBlue ®
in accordance with ISO
22241. Do not use additives with AdBlue ®
and do not dilute AdBlue ®
with water. This
may destroy the BlueTEC exhaust gas after-
treatment system.
Purity !
Impurities in AdBlue ®
(e.g. due to other
servic eproducts, cleaning agents or dust)
lead to:
R increased emissio nvalues
R damage to the catalytic converter Service product
