tem and the engine
.The repair costs are
high. 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/85 MON that conforms to
European standard EN 228 or E DIN
51626-1 or an equivalent specification.
Fuel with this specification may contain up
to 10 % ethanol.
! Do not use the following:
R E85 (petrol with 85 % ethanol)
R E100 (100 %ethanol)
R M15 (petrol with 15 % methanol)
R M85 (petrol with 85 % methanol)
R M100 (100 % methanol)
R Petrol with metallic additives
R Diesel
Do not mix these fuels with petrol, and do
not use any additives. This can otherwise
lead to engine damage. This does not
include cleaning additives for the removal
and prevention of residue build-up. Only
cleaning additives recommended by
Mercedes-Benz should be added to petrol,
see "Additives". You can obtain further
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 can refuel your vehicle using E10
fuel.
i As a temporary measure, if the recom-
mended fuel is not available, you may also
use unleaded petrol with an octane rating
of 91 RON/82 MON. This may reduce
engine performance and increase fuel con-
sumption .Avoid driving at full throttle.
Information on refuelling (Y page 162).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 outpu tor
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 regularu nleaded petrol with an
octane rating of 91 RON/82.5 MON or
lowe ris 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 can refuel your vehicle using E10
fuel.
CLS 350 BlueEFFICIENCY
! 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 388
Service products and capacitiesTechnical data

<10p
pm) is used for refuelling, the odours
are reduced.
Additives
! Operating the engine with fuel additives
can cause wear in the fuel high-pressure
pump and contaminate the entire fuel sys-
tem. The repair costs are high. 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 .More information about
recommended additives can be obtained
from any Mercedes-Benz Service Centre.
One of the major problems with low-grade
fuel is the creation of carbon deposits during
the process of burning fuel. Mercedes-Benz
recommends that you use fuel brands that
have additives.
If you use fuels without these additives for a
longer period of time, there may be a build-up
of carbon deposits. These will form especially
on the inlet valves and in the combustion
chamber.
This could lead to engine running problems,
e.g.:
R longer engine warm-up phase
R uneven idle
R engine noise
R misfiring
R loss of power
In areas where petrol with the required addi-
tives is not available, carbon deposits can
build up. In this case, Mercedes-Benz recom-
mends the use of additives that have been
approved for Mercedes-Benz vehicles; see
http://bevo.mercedes-benz.com.
The quality of the fuel available in some coun-
tries may not be sufficient .Residue could
build up as a result. In such cases, and in
consultation with a Mercedes-Benz Service
Centre, the petrol may be mixed with the
additive recommended by Mercedes-Benz
(part no. A000989254510). You must
observe the notes and mixing ratios specified
on the container. Consult a Mercedes-Benz Service Centre to
view a list of approved products. Observe the
instructions for use in the product descrip-
tion.
Do not mix other fuel additives with fuel. This
causes unnecessary costs and could damage
the engine.
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 arisk 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 equivalen tquality. Fuel that does
not conform to EN 590 can lead to
increased wear as well as damage to the
engine and exhaust system.
! Do no tuse 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.T his
does not include flow improver additives.

! Vehicles without adiesel particle fil-
ter: in countries where only diesel fuel with
a high sulphur conten tis available, you will
need to carry out your vehicle's oil change
at shorter intervals. More information
aboutt he 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 162).
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 climati cconditions.
i Further information on country-specific
fuel properties can be obtained from oil
companies, e.g. at filling stations.
Flow improvers
To improve the low-temperature resistance of
diesel fuel, a flow improver can be attached.
The effectiveness of a flow improver is not
guaranteed for every fuel.
Only use flow improvers tested and approved
by Mercedes-Benz. During use, please
observe the information on operation.
Correct dosage and sufficient mixing are deci-
sive in improving low-temperature resistance
with the flow improver. Overdosage can
potentially even decrease low-temperature
resistance and must therefore be avoided. Follow the manufacturer's guidelines on dos-
age.
Mix the additive into the diesel in good time,
before the flow characteristics of the diesel
become insufficient. Otherwise, malfunctions
can arise through heating the fuel system,
e.g. through parking in a heated garage.
More information about recommended flow
improvers can be obtained from any qualified
specialist workshop.
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 or road conditions
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 version:
R for vehicles that comply with standards
up to and including the EURO 4standard, 390
Service products and capacitiesTechnical data

in accordance with EU Directive
80/1268/EEC
R for vehicles that comply with or exceed
the EURO 5standard, in accordance with
Regulation (EC )No. 715/2007
Deviations from these values may occur
under normal operating conditions. Engine oil
General notes The quality of the engine oil is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Benz approves
engine oils that correspond to the current
technical standard.
Therefore, only Mercedes-Benz approved
engine oils may be used in Mercedes-Benz
engines.
Further information on tested and approved
engine oils can be obtained from any
Mercedes-Benz Service Centre. Mercedes-
Benz recommends that you have the oil
change carried out at a qualified specialist
workshop. Mercedes-Benz approval is indica-
ted on the oil container by the inscription "MB
Approval" and the corresponding designa-
tion, e.g. MB Approval 229.51.
You can call up an overview of approved
engine oils on the Internet at:

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
Over a period of time, the brake fluid absorbs
moisture from the air; This lowers its boiling
point.
If the boiling point of the brake fluid is too low,
vapour pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This impairs braking effi-
ciency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change inter-
vals 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 renewed regularly at
a qualified specialist workshop. Coolant
