R Gasoline with metalliferous additives
R Diesel
Do not mix such fuels with the fuel recom-
mended for your vehicle. Do not use addi-
tives. Otherwise, engine damage may
occur. This does not include cleaning addi- tives for the removal and prevention of res-
idue build-up. Gasoline may only be mixed
with cleaning additives recommended by
Mercedes-Benz; see "Additives". You can
obtain further information from any author- ized Mercedes-Benz Center.
! To ensure the longevity and full perform-
ance of the engine, only premium-grade
unleaded gasoline must be used.
If standard unleaded gasoline is unavaila-
ble and you have to refuel with unleaded
gasoline of a lower grade, observe the fol-
lowing precautions:
R Only fill the fuel tank to half full with reg-
ular unleaded gasoline and fill the rest
with premium-grade unleaded gasoline
as soon as possible.
R Do not drive at the maximum speed.
R Avoid sudden acceleration and engine
speeds over 3,000 rpm.
You will usually find information about the fuel
grade on the pump. If you cannot find the
label on the pump, ask the staff for assis-
tance.
i For further information, consult a quali-
fied specialist workshop or visit
http://www.mbusa.com (USA only).
i E10 fuel contains up to 10% bioethanol.
Your vehicle is E10-compatible. You can
refuel your vehicle using E10 fuel.
CLA 250, CLA 250 Sport, CLA 250
4MATIC, CLA 250 Sport 4MATIC: as a tem-
porary measure, if the recommended fuel is
not available, you may also use regular unlea-
ded gasoline 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 gasoline with
an octane rating of 87 AKI/91 RON. This may
reduce engine performance and increase fuel consumption. Avoid driving at full throttle andsudden acceleration. Never refuel using fuel
with a lower AKI.
Information on refueling (Y page 159).
AMG vehicles
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 buildup. gasoline
must only be mixed with additives recom-
mended by Mercedes-Benz. Comply with
the instructions for use on the product
label. More information about recommen-
ded additives can be obtained from any
authorized Mercedes-Benz Center.
Mercedes-Benz recommends that you use
branded fuels 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
such cases, and in consultation with an
authorized Mercedes-Benz Center, the gaso-
line may be mixed with the cleaning additive
recommended by Mercedes-Benz. You must
observe the notes and mixing ratios specified on the container.
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: Service products and filling capacities

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 minimize 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 city traffic
R on short journeys
R in mountainous terrain Engine oil
General notes !
Never use engine oil or an oil filter of a
specification other than is necessary to ful- fill the prescribed service intervals. Do not
change the engine oil or oil filter in order to
achieve longer replacement intervals than
those prescribed. You could otherwise
cause engine damage or damage to the
exhaust gas aftertreatment.
Follow the instructions in the service inter-
val display regarding the oil change. Other-
wise, you may damage the engine and the
exhaust gas aftertreatment.
When handling engine oil, observe the impor- tant safety notes on service products
(Y page 353).
The engine oils are matched to the perform-
ance of Mercedes-Benz engines and service
intervals. You should therefore only use
engine oils and oil filters that are approved for
vehicles with maintenance systems.
For a list of approved engine oils and oil filters, consult an authorized Mercedes-Benz Cen-
ter. Or visit the website
http://bevo.mercedes-benz.com. The table shows which engine oils have been
approved for your vehicle. Model MB Approval

Use only SAE 0W-40o

i MB approval is indicated on the oil con-
tainers.
Filling capacities The following values refer to an oil change

!
Do not use any additives in 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,
this means that it is thick; a low viscosity
means that it is thin.
Select an engine oil with an SAE classification (viscosity) suitable for the prevailing outside
temperatures. The table shows you which
SAE classifications are to be used. The low-
temperature characteristics of engine oils 356
