WARNING
Do not use petrol to refue lvehicles with adie-
sel engine. Do not mix diesel with petrol. This
would result in damage to the fuel system and
engine, which coul dleadtoav ehiclefire.
! Do not use petrol to refue lvehicles with a
diesel engine. Do not use diesel to refuel
vehicles with apetrol engine. Even small
amounts of the wrong fuel result in damage
to the fuel system and the engine.
! Do not switch on the ignitio nifyou acci-
dentally refue lwith the wrong fuel .Other-
wise ,the fuel will ente rthe fuel lines. Notify
aq ualified 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. Mor einformatio nabout
recommended additives can be obtained
from any Mercedes-Benz Service Centre. !
Use afilter when adding fuel from afuel
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 atemporary measure, you may
also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engin eperformanc eand increase fuel con-
sumption .Avoid driving at full throttle.
In some countries, the fuel grad eavailable
may not be adequate and coul dcause
deposits to build up. In such cases, and in
consultation with aMercedes-Benz Service
Centre, the petrol may be mixed with the
additive recommende dbyMercedes-Benz
(part number A000989254510). You must
observe the notes and mixing ratios speci-
fied on the container.

(Y page3 34).
E3 00 BlueEFFICIENCY and E350 Blue-
EFFICIENCY !
Only refue lusing unleaded, sulphur-free
premium-grade petrol with at least
95 RON/85 MON, which conforms to Euro-
peans tandard EN 228 or an equivalent
specification.
You can otherwise impair engine outpu tor
damage the emission contro lsystem.
i In some countries, the available petrol
may not be sufficiently low in sulphur. This
fuel can temporarily produce unpleasant
odours, especially on short journeys. As
soon as sulphur-free fuel (sulphur content
<10p pm) is used for refuelling, the odours
are reduced. Refuelling

Diesel (EN 590)
Fuel grade !
Whe nrefuelling, only use diesel fuel that
conforms to the European standard EN 590
or is of equivalent quality. You can other-
wise impair engin eoutput or damage the
engine.
! Vehicles with diesel particle filters: in
countries outside the EU, only use low sul-
phur Euro diesel with asulphur contentof
under 50 ppm .Otherwise, the emission
control syste mcould be damaged.
! Vehicles without adiesel particle fil-
ter: in countries where only diesel fuels
with ahigher sulphur conten tare available,
the vehicle's oil change interval sare
shorter. More information about intervals
for changing the oil can be obtained from
any Mercedes-Benz Service Centre.
! Only use fuel that complies with the EN
590 European standard .Fuel that does not
comply wit hEN590can lead to increased
wear, engin edamag eand damag etothe
exhaust system.
Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not mix these fuels with diesel fuels and
do not use any special additives. Other-
wise, this can lead to damage to the engine.
This excludes flow improver; see "Low out-
side temperatures".
! Use afilter when adding fuel from afuel
can. Otherwise, the fuel lines and/or the
diesel injection system could be blocked by
particles from the fuel can. For further information on "Fuel", see
(Y
page 334).
Low outside temperatures Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, various climate-dependent low-tem-
perature classes are defined in EN 590. Refu-
elling with diesel fuel which complies with the
climatic specification sofstandard EN 590
can help to prevent operating problems. At
exceptionally low temperatures, it is possible
that the flow properties of the fuel may be
inadequate. This also applies to fuel that has
not been adapted to suit the climatic condi-
tions, e.g. diesel fuel from warmer regions.
i Further information about country-spe-
cific fuel properties can be obtained from
oil companies, e.g. at filling stations.
Flow improver Flow improvers can be added to improve the
cold resistanc
eofdiesel fuel. The effective-
ness of aflow improver is not guaranteed with
every fuel.
Correct dosage and thorough mixing are deci-
sive factor sinensuring improvement in low-
temperature resistance. Under certain cir-
cumstances, an excessive dosage may
actually decrease low-temperature resist-
ance and should therefor ebeavoided. Follow
the manufacturer's dosing instructions.
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Malfunction scan other-
wise only be rectified by heating the entire
fuel system, e.g. by parking the vehicle in a
heated garage.
Observe the information provided by the man-
ufacturer when using aflow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain
further information from any Mercedes-Benz
Servic eCentre. 162

global warming (the greenhouse effect). Your
vehicle's CO 2emissions are directly related
to fuel consumption and therefor edepend on:
R efficient use 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 carefully and having it serv-
iced regularly. Engine oil
Please bear the following in mind The quality of engine oils is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Benz approves
engine oils which correspon dtothe current
technical standard.
Therefore, only Mercedes-Benz approved
engine oils may be used in Mercedes-Benz
engines.
Further information on tested and approved
engine oils can be obtained from any
Mercedes-Benz Service Centre. Mercedes-
Benz recommends that you have the oil
change carried out at aMercedes-Benz
Service Centre. Mercedes-Benz approval is
indicated on the oil container by the inscrip-
tion "MB Approval" and the corresponding
designation, e.g. MB Approval 229.51.
