Fuel grade
! Do not use diesel to refuel vehicles with a
petrol engine. Do not switch on the ignition if you accidentally refuel with the wrong
fuel. Otherwise, the fuel will enter the fuel
system. Even small amounts of the wrong
fuel can result in damage to the fuel system
and the engine. Notify a qualified specialist
workshop and have the fuel tank and fuel
lines drained completely.
! Only refuel using unleaded petrol with at
least 95 RON that conforms to the Euro-
pean standard EN 228 or E DIN 51626-1 or
an equivalent specification.
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.
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.
i E10 fuel contains up to 10% bioethanol.
Your vehicle is suitable for use with E10
fuel. You may refuel your vehicle using E10
fuel.
! Only use the fuel recommended. Operat-
ing the vehicle with other fuels can lead to
engine failure.
! 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.
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 sta-
tion staff.
A 200, A 250, A 250 4MATIC, A 250 Sport:
as a temporary measure, if the recommendedfuel is not available, you may also use regular
unleaded petrol with an octane rating 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 performance and increase fuel con-
sumption. Avoid driving at full throttle and
sudden acceleration. Never refuel using fuel
with a lower RON.
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
<1 0 ppm) is used for refuelling, the odours
are reduced.
Information on refuelling (Y page 181).
Mercedes-AMG vehicles ! Only refuel using super unleaded petrol
with at least 98 RON, that conforms to the
European standard EN 228 or E DIN
51626-1 or an equivalent specification.
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 recom-
mended fuel is not available, you may also 398

use unleaded petrol with an octane rating
of 95 RON. This may reduce engine per-
formance and increase fuel consumption.
As much as possible, avoid driving at full
throttle.
! As a temporary measure, if the recom-
mended 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
consumption, and the engine power output is noticeably reduced. Avoid driving at full
throttle.
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
qualified specialist workshop.
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
prevention of residue build-up. Petrol must only be mixed with additives recommended
by Mercedes-Benz. Observe the instruc-
tions for use in the product description.
More information 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 injection system as a result. In
this case, in consultation with a Mercedes-
Benz Service 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

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. Other-
wise, engine damage may occur.
! Vehicles with diesel particle filters:
in
countries outside the EU, only use low sul-
phur Euro diesel with a sulphur content of
under 50 ppm. Otherwise, the emission
control system could be damaged.
! Vehicles without a diesel particle fil-
ter: in countries where only diesel fuel with
a high sulphur content is available, you will need to carry out your vehicle's oil change
at shorter intervals. More information
about the interval for oil change can be
obtained from any qualified specialist
workshop.
