workshop and have the fuel tank and fuel
lines drained completely.
! Only refuel using premium-grade unlea-
ded petrol with at least 95 ROZ/85 MOZ,
that conforms to European standard
EN 228 or E DIN 51626–1 or an equivalent specification.
Fuel of this specification can contain up to
10 % ethanol.
Fuel that does not conform to EN 228 or
E DIN 51626–1 can lead to increased wear
and damage the engine and exhaust sys-
tem.
! 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. Do not use addi-
tives. This can otherwise lead to engine
damage. This does not include cleaning
additives for the removal and prevention of residue build-up. Petrol must only be mixed
with additives recommended by Mercedes- Benz; see "Additives". You can obtain fur-
ther information from any Mercedes-Benz
Service Centre.
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.
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. GLA 200, GLA 250, GLA 250 4MATIC:
as a
temporary measure, if the recommended fuel
is not available, you may also use regular
unleaded petrol with an octane rating of
93 RON/83 MON.
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/82 MON. This may
reduce engine performance and increase fuel consumption. Avoid driving at full throttle andsudden acceleration. Never refuel using fuel
with a lower RON/MON.
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 175).
AMG vehicles ! Only refuel using super unleaded petrol
with at least 98 RON/88 MON that con-
forms to European standard EN 228 or an
equivalent specification.
You can otherwise impair engine output or
damage the engine.
! Premium-grade unleaded petrol with an
octane rating of 95 RON/85 MON may be
used as a temporary measure if the recom-
mended fuel is not available. This may
reduce engine performance and increase
fuel consumption. As much as possible,
avoid driving at full throttle.
! Regular unleaded petrol with an octane
rating of 91 RON/82.5 MON may also be
used as a temporary measure if the recom-
mended fuel is not available.
Doing so results in noticeably higher fuel
consumption, and the engine power output is noticeably reduced. Avoid driving at full
throttle. 386
Service products and capacitiesTechnical data

If only regular unleaded petrol with an
octane rating of 91 RON/82.5 MON or
lower is available, you must have the vehi-
cle adapted to this fuel at a qualified spe-
cialist workshop.
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.
GLA 250 ! Only refuel using unleaded, sulphur-free
unleaded petrol with at least 95 RON/
85 MON that conforms to European stand-
ard EN 228 or an equivalent specification.
You could 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
<1 0 ppm) is used for refuelling, the odours
are reduced.
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 (EN 590) 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. This can
otherwise lead to engine damage.
! 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 Service products and capacities
