‑1)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, fuel can enter the fuel sys- tem. Even small amounts of the wrong fuel could 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 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.
CLA 200, CLA 250, CLA 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 fuelconsumption. 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.

Service products and capacitiesTechnical data
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.
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.
CLA 250 4MATIC ! Only refuel using premium-grade 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. Service products and capacities

!
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
obtained from any qualified specialist
workshop.
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.
Information on refuelling (Y page 163).
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 specifi-
cations outlined in EN 590. At unusually low
outside temperatures, it is possible that the
flow characteristics of the diesel fuel could be
insufficient. Accordingly, diesel fuel from
warmer areas may not be suitable for opera-
tion in colder climatic conditions. i
Further information on country-specific
fuel properties and fuel types with low-tem-
perature resistance can be obtained from
oil companies, e.g. at filling stations.
Fuel consumption information H
Environmental note
CO 2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO 2emissions are directly related to
fuel consumption and therefore depend on:
R efficient use of the fuel by the engine
R driving style
R other non-technical factors, such as envi-
ronmental influences, road conditions or
traffic flow
You can minimise your vehicle's CO 2emis-
sions by driving carefully and having it serv-
iced regularly.
The vehicle will use more fuel than usual in the following situations:
R at very low outside temperatures
R in urban traffic
R on short journeys
R in mountainous terrain
R when towing a trailer
i Only for certain countries: you can find
the current consumption and emission val-
ues of your vehicle in the COC documents
(EU CERTIFICATE OF CONFORMITY). These documents are delivered with your vehicle.
The consumption figures were, in each
case, based on the currently applicable ver-sion:
R for vehicles that comply with standards
up to and including the EURO 4 standard,
in accordance with EU Directive
80/1268/EEC
R for vehicles that comply with or exceed
the EURO 5 standard, in accordance with
Regulation (EC) No. 715/2007 358

Additives
!
Do not use any additives with the engine
oil. This could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity
rating, it flows slowly; the lower the viscosity,
the faster it flows.
Engine oil selection is based on the respective outside temperatures and in accordance with
the SAE classification (viscosity). The table
shows you which SAE classifications are to be
used. The low-temperature properties of
engine oils can be significantly impaired dur-
ing operation due to, for example, ageing or
soot and fuel accretion. It is therefore
strongly recommended to observe regular oil changes using an approved engine oil with the
appropriate SAE classification. Brake fluid
G
WARNING
The brake fluid continuously absorbs mois-
ture from the air. This results in the boiling
point of the brake fluid lowering. If the boiling
point of the brake fluid is too low, vapour pockets may form when the brakes are sub-
jected to a heavy load. This would impair brak-
ing efficiency. There is a risk of an accident.
Have the brake fluid renewed at the prescri-
bed intervals.
When handling brake fluid, observe the
important safety notes on service products
(Y page 354).
The brake fluid change intervals can be found
in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
shop or on the Internet at
http://bevo.mercedes-benz.com.
i Have the brake fluid regularly replaced at
a qualified specialist workshop. Coolant
Important safety notes G
WARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you top up
the antifreeze. Make sure that antifreeze is
not spilled next to the filler neck. Thoroughly
clean the antifreeze from components before
starting the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications for Service Products, MB Specifications for Service Products 310.1, e.g. on the Inter-
net at http://bevo.mercedes-benz.com.
