G
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 Petrol with metallic additives
R Diesel
Do not mix fuels such as this with petrol
and do not use any additives. Doing so may
cause engine damage. This does not
include additives for the removal and pre-
vention 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 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 E10 fuel contains up to 10% bioethanol.
Your vehicle is E10 compatible. You can
refuel your vehicle using E10 premium-
grade petrol.
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 consultation with a
Mercedes-Ben zService Centre, this petrol
may be mixed with the additive recommen-
ded by Mercedes-Benz( part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.
For further information on "Fuel", see
(Y page 380).
AMG vehicles !
Only refuel using super-grade unleaded
petrol with at least 98 RON/88 MON,
which conforms to European standard EN
228 or equivalent.
You can otherwise impair engine output or
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. Refuelling
169Driving and parking Z

However, using this fuel results in consid-
erably higher petrol consumptio
nand sig-
nificantly reduced engine performance.
Avoid driving at full throttle.
If no fuel othe rthan regular petrol with
91 RON/82.5 MON or a lower grade is per-
manently available, you should have the
vehicle adapted to run on this fuel in a
qualified specialist workshop. Mercedes-
Benz recommends that you use a
Mercedes-Ben zService Centre for this pur-
pose.
C 350 BlueEFFICIENCY and C 350
4MATIC BlueEFFICIENCY !
Only refuel using unleaded, sulphur-free
premium-grade petrol with at least
95 RON/85 MON, which conforms to Euro-
pean standard EN 228 or an equivalent
specification.
You can otherwise impair engine output or
damage the emission control system.
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. Diesel (EN 590)
Fuel grade !
When refuelling, only use diesel fuel that
conform stothe European standard EN 590
or is of equivalent quality. You can other-
wise impair engine output or damage the
engine.
! Vehicles with diesel particle filters: in
countries outside the EU, only use low sul-
phur Euro diesel with a sulphurc ontent of
under 50 ppm. Otherwise, the emission
control system could be damaged. !
Vehicles without adiesel particle fil-
ter: in countries where only diesel fuels
with a higher sulphur conten tare available,
the vehicle's oil change intervals are
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 with EN 590 can lead to increased
wear, engine damage and damag eto the
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 a filter when adding fuel from a fuel
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 380).
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 specifications of standard 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 170

not been adapted to suit the climatic condi-
tions, e.g .diesel fuel fro mwarmer regions.
i Further information about country-spe-
cific fuel properties can be obtained from
oil companies, e.g .atfilling stations.
Flow improver Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective-
ness of a flow improver is not guaranteed with
every diesel fuel.
Correct dosage and thorough mixing are deci-
sive factors in ensuring improvement in low-
temperature resistance. Avoid excessive dos-
age. Excessive dosage may actually decrease
low-temperature resistance under certain cir-
cumstances. Follow the manufacturer's dos-
ing instructions.
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Malfunctions can 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 a flow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain
further information from any Mercedes-Benz
Service Centre. Refuelling
