at a qualified specialist workshop.
Before driving your vehicle outside Europe, have
the AdBlue ®
supply checked at a qualified spe-
cialist workshop.
Further information about BlueTEC exhaust gas
aftertreatment and about AdBlue ®
can
be obtained from any Mercedes-Benz Service
Centre.
Important safety notes AdBlue
®
is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
R non-toxic
R colourless and odourless
R non-flammable
If you open the AdBlue ®
tank, small amounts of
ammonia vapour may be released.
Ammonia vapours have a pungent odour and are
particularly irritating to the skin, mucous mem-
branes and eyes. You may experience a burning sensation in your eyes, nose and throat. You
may also experience coughing and watery eyes.
Do not inhale any ammonia vapours that may be
released. Fill the AdBlue ®
tank only in well-ven-
tilated areas. Do not swallow AdBlue
®
or let it come into con-
tact with your skin, eyes or clothing. Keep
AdBlue ®
away from children.
If you or others come into contact with AdBlue ®
,
observe the following:
R immediately rinse AdBlue ®
off your skin with
soap and water.
R if AdBlue ®
comes into contact with your eyes,
immediately rinse them thoroughly with clean water. Seek medical attention immediately.
R if AdBlue ®
is swallowed, immediately rinse
your mouth out thoroughly. Drink plenty of
water. Seek medical attention immediately.
R change immediately out of clothing that has
come into contact with AdBlue ®
.
! Only use AdBlue ®
in accordance with
ISO 22241. Do not mix any additives with
AdBlue ®
, and do not dilute AdBlue ®
with
water. This may destroy the BlueTEC exhaust
gas aftertreatment system.
! In order to fill the AdBlue ®
tank, the vehicle
must be parked on a level surface. The
AdBlue ®
tank can only be filled as intended
with the vehicle parked on a level surface.
Fluctuations in capacity will thus be avoided.
Filling a vehicle standing on an uneven sur-
face is not permitted. There is a danger of
overfilling, which can cause damage to Blue-
TEC exhaust gas aftertreatment components.
! Surfaces which have come into contact with
AdBlue ®
while refilling should be rinsed
immediately with water, or remove AdBlue ®
with a moist cloth and cold water. If AdBlue ®
has already crystallised, use a sponge and
cold water to clean the area. AdBlue ®
residue
crystallises after a certain amount of time and
soils the affected surfaces.
! AdBlue ®
is not a fuel additive and must not
be added to the fuel tank. If AdBlue ®
is added
to the fuel tank, this can lead to engine dam- age.
Have the AdBlue ®
tank refilled at a qualified
specialist workshop. However, you can also top
up the AdBlue ®
tank:
R at a filling station with an AdBlue ®
filling pump
R with AdBlue ®
refill bottles
R with an AdBlue ®

Service products and capacitiesTechnical data

Fuel that does not conform to EN 228 can lead
to increased wear as well as damage to the
fuel system, engine and exhaust system.
! Only use the fuel recommended. Operating
the vehicle with other fuels can lead to dam-
age to the fuel system, engine and exhaust
system.
! Do not use the following:
R E85 (petrol with 85% ethanol)
R E100 (100% ethanol)
R M15 (petrol with 15% methanol)
R M30 (petrol with 30% methanol)
R M85 (petrol with 85% methanol)
R M100 (100% methanol)
R petrol with additives containing metal
R diesel
Do not mix such fuels with the fuel recom-
mended for your vehicle.
You will usually find information about the fuel
quality on the pump. If you cannot find the label on the petrol pump, ask the filling station staff.
C 180, C 250: as a temporary measure, if the
recommended fuel is not available, you may also
use regular unleaded petrol with an octane rat-
ing of 93 RON.
All other models: as a temporary measure, if
the recommended fuel is not available, you may
also use regular unleaded petrol with an octane rating of 91 RON. This may reduce engine per-
formance and increase fuel consumption. Avoiddriving at full throttle and sudden acceleration.
Never refuel using fuel with a lower RON.
i In some countries, the petrol available may
not be sufficiently low in sulphur. This fuel can temporarily produce unpleasant odours,
especially on short journeys. As soon as sul-
phur-free fuel (sulphur content < 10 ppm) is
used for refuelling, the odours are reduced.
Information on refuelling (Y page 154).
Mercedes-AMG vehicles
! Only refuel using super unleaded petrol with
at least 98 ROZ, that conforms to European
standard EN 228 or an equivalent specifica-
tion.
You can otherwise impair engine output or
damage the engine.
Fuel of this specification may contain up to
10% ethanol. Your vehicle is suitable for use with E10 fuel. You may refuel your vehicle
using E10 fuel.
! As a temporary measure, if the recommen-
ded fuel is not available, you may also use
unleaded petrol with an octane rating of
95 RON. This may reduce engine perform-
ance and increase fuel consumption. As much as possible, avoid driving at full throttle.
! As a temporary measure, if the recommen-
ded fuel is not available, you may also use
unleaded petrol in emergencies with an
octane rating of 91 RON.
Doing so results in noticeably higher fuel con- sumption, and the engine power output is
noticeably reduced. Avoid driving at full throt- tle.
If no fuel other than petrol with 91 RON or a
lower grade is available, you should have the
vehicle adapted to run on this fuel at a quali-
fied specialist workshop.
C 200, C 250
! Only refuel using sulphur-free unleaded pet-
rol with at least 95 ROZ, that conforms to the
European standard EN 228 or E DIN or an
equivalent specification.
You could otherwise impair engine output or
damage the emission control system.
i The petrol available in some countries may
not be sufficiently low in sulphur. This fuel can temporarily produce unpleasant odours,
especially on short journeys. As soon as sul-
phur-free fuel (sulphur content < 10 ppm) is
used for refuelling, the odours are reduced.
C 300, Mercedes-AMG C 43 4MATIC
! Only refuel using super unleaded petrol with
at least 98 ROZ, if you want maximum per-
formance from the engine. Alternatively, you
can also use unleaded petrol of at least
95 ROZ.
As a temporary measure, if the recommended
fuel is not available, you may also use regular
unleaded petrol with an octane rating of
91 ROZ. Doing so results in higher fuel con-
sumption and significantly reduced perform-
ance. Never refuel using fuel with a lower
RON.
Fuel of this specification may contain up to
10% ethanol. 362
Service products and capacitiesTechnical data

Fuel that does not conform to EN 228 or E DIN
51626–1 can lead to increased wear as well
as damage to the engine and exhaust system.
Additives ! Operating the engine with fuel additives
added later can lead to engine failure. Do not mix fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residue build-up. Petrol must only be
mixed with additives recommended by
Mercedes-Benz. Observe the instructions for
use in the product description. More informa- tion about recommended additives can be
obtained from any Mercedes-Benz Service
Centre.
Mercedes-Benz recommends that you use fuel
brands containing additives.
The quality of the fuel available in some coun-
tries may not be sufficient. Residue could build
up in the fuel injection system as a result. In this case, in consultation with a Mercedes-Benz Ser-
vice Centre, the petrol may be mixed with the
cleaning additive recommended by Mercedes-
Benz. Always observe the notes and mixing
ratios specified on the container.
Diesel Fuel grade
G
WARNING
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is a risk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590 or is of equivalent quality. Fuel that does not
conform to EN 590 can lead to increased wear
as well as damage to the engine and 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 such fuels with diesel fuel and do
not use any special additives. Otherwise,
engine damage may occur.
Usually you will find information about the fuel
grade on the pump. If you cannot find the label
on the petrol pump, ask the filling station staff.
Information on refuelling (Y page 154).
Low outside temperatures In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc-
tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifica-
tions outlined in EN 590. At unusually low out-
side temperatures, it is possible that the flow
characteristics of the diesel fuel could be insuf- ficient. Accordingly, diesel fuel from warmer
areas may not be suitable for operation in colderclimatic conditions.
i Further information on country-specific fuel
properties and fuel types with low-tempera-
ture resistance can be obtained from oil com- panies, e.g. at filling stations.
Flexible-fuel vehicles Important safety notes
G
WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before refuelling. G
WARNING
Fuels are poisonous and hazardous to health. There is a danger of injury.
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren. Service products and capacities

Z

If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek
immediate medical attention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately.
Flexible-fuel vehicles can be refuelled with the
following fuel types:
R Unleaded petrol
R E85 fuel
R a mixture of E85 fuel and unleaded petrol
i Flexible-fuel vehicles can be identified by
the Ethanol up to E85 sticker on the inside of
the fuel filler flap.
Fuel consumption
The energy content of E85 fuel is lower than the energy content of the same amount of unleaded
petrol. Therefore, fuel consumption on E85 fuel is higher than on unleaded petrol.
Service
Inform your Mercedes-Benz Service Centre if
you drive or have driven your vehicle on E85 fuel.
Low outside temperaturesIf the outside temperature is below 0 †, the
starting procedure can take noticeably longer
with E85 fuel.
E85 fuel is not suitable for use at outside tem-
peratures under -20 †. AdBlue
®
Important safety notes Comply with the important safety notes for ser-
vice products when handling AdBlue ®
(Y page 360). AdBlue
®
is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
R non-toxic
R colourless and odourless
R non-flammable
If you open the AdBlue ®
tank, small amounts of
ammonia vapour may be released.
Ammonia vapours have a pungent odour and are
particularly irritating to the skin, mucous mem-
branes and eyes. You may experience a burning sensation in your eyes, nose and throat. You
may also experience coughing and watery eyes.
Do not inhale any ammonia vapours that may be
released. Fill the AdBlue ®
tank only in well-ven-
tilated areas.
Low outside temperatures AdBlue
®
freezes at a temperature of approx-
imately -11 †. The vehicle is delivered from the
factory equipped with an AdBlue ®
preheating
system. Winter operation can thus be guaran-
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 ser-
vice products, cleaning agents or dust) lead
to:
R increased emission values
R damage to the catalytic converter
R engine damage
R malfunctions in the BlueTEC ®
exhaust gas
aftertreatment system
Assuring the purity of AdBlue ®
is particularly
important with regard to avoiding malfunctions
in the BlueTEC exhaust gas aftertreatment sys-
tem.
If AdBlue ®
is pumped out of the AdBlue ®
tank,
e.g. during repair work, do not use this fluid to
refill the tank. The purity of the fluid can no lon-
ger be guaranteed. 364
