WARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is ariskoff irea nd explo-
sion.
You must avoi dfire, naked flames, creating
sparks and smoking. Switc hoff th eengine

driving at full throttle and sudden acceleration.
Never refuel using fuel with alower RON.
i In some countries, the available petro
lmay
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 conten t<10ppm) is
used for refuelling, the odours are reduced.
Information on refuelling (Y page 167).
Mercedes-AMG vehicles
! Only refuel using super unleaded petro
lwith
at least 98 ROZ, that conform stoEuropean
standard EN 228 or an equivalent specifica-
tion.
You can otherwise impair engin eoutput 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
atemporary measure, if the recommen-
ded fuel is not available, you may also use
unleaded petro lwith an octane ratin gof
95 RON. This may reduce engin eperform-
ance and increase fuel consumption .Asmuch
as possible, avoid driving at full throttle.
! As
atemporary measure, if the recommen-
ded fuel is not available, you may also use
unleaded petro linemergencies with an
octane ratin gof91RON.
Doin gsor esults in noticeably higher fuel con-
sumption ,and the engin epower output is
noticeably reduced. Avoid driving at full throt- tle.
If no fuel other than petro lwith 91 RON or a
lower grade is available, you should have the
vehicle adapted to run on this fuel at aquali-
fied specialist workshop.
C2 00, C250
! Only refuel using sulphur-free unleaded pet-
rol with at least 95 ROZ ,that conform stothe
European standard EN 228 or EDIN or an
equivalent specification.
You could otherwise impair engin eoutput or
damage the emission control system.
i In some countries, the available petro
lmay
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 conten
t<10ppm) is
used for refuelling, the odours are reduced.
C3 00
! Only refuel using super unleaded petro
lwith
at least 98 ROZ, if you want maximum per-
formance from the engine. Alternatively, you
can also use unleaded petro lofatleast
95 ROZ.
As atemporary measure, if the recommended
fuel is not available, you may also use regular
unleaded petro lwith an octane ratin gof
91 ROZ. Doin gsoresults in higher fuel con-
sumption and significantly reduced perform-
ance. Never refuel using fuel with alower
RON.
Fuel of this specification may contain up to
10% ethanol.
Fuel that does not conform to EN 228 or EDIN
51626–1 can lead to increased wear as well
as damage to the engin eand exhaust system.
Additives ! Operatin
gthe engin ewith fuel additives
added later can lead to engin efailure. Do not
mix fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residue build-up. Petro lmust only be
mixed with additives recommended by
Mercedes-Benz.O bserve 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 that have 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 aresult. In this
case, in consultation with aMercedes-Benz Ser-
vice Centre, the petro lmay be mixed with the
cleanin gadditive recommended by Mercedes-
Benz. Always observe the notes and mixing
ratios specified on the container.

Lo wo utside temperatures
In winter months, diese lfue lw ithani mproved
cold flo wquality is available .InEurope, the
EN 590 standard defines variou sclimate-
dependent temperature categories. Malfunc-
tions can be avoided by refuelling with diesel
fue lthat corresponds to the climati cspecifica-
tions outlined in EN 590. At unusually low out-
sid etemperatures, it is possible that the flow
characteristics of the diese lfue lcould be insuf-
ficient. Accordingly ,diese lfue lfrom warmer
areas may not be suitabl efor operation in colder
climati cconditions.
i Further information on country-specific fuel
properties and fue ltypes with low-tempera-
ture resistance can be obtained from oil com- panies ,e.g. at filling stations. AdBlue

is aw ater-solubl efluid for the exhaust
ga sa ftertreatment of diese lengines. It is:
R non-toxic
R colourless and odourless
R non-flammable
If yo uopent he AdBlue ®

ammonia vapou rmay be released.
Ammoni avapours have apungent odour and are
particularly irritating to the skin, to mucous
membrane sand to the eyes. You may experi-
ence aburning 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 .Only fil lthe AdBlue ®

freezes at atemperature of approx-
imately -11 †. The vehicle is delivered from the
factory equipped with an AdBlue ®

Purity !
Impurities in AdBlue ®
(e.g .due to othe rser-
vice products, cleaning agents or dust) lead
to:
R increase demission values
R damag etothe catalytic converter
R engine damage
R malfunctions in the BlueTEC ®

Assuring the purity of AdBlue ®
is particularly
important with respect to avoiding malfunctions
in the BlueTEC exhaus tgas aftertreatment sys-
