Do not mix these fuels with petrol and do
not use any special additives. Otherwise,
this can lead to damage to the engine. This
does not include additives for the removal
and prevention of residue build-up on the
inlet valves.
! Use a filter when adding fuel from a fuel
can. The fuel lines and/or the diesel injec-
tion system could otherwise be blocked by
particles from the fuel can.
i If the recommended fuel is not available,
but only as a temporary measure, you may
also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the fuel grade available
may not be adequate and could cause res-
idue to build up around the inlet valves. In
such cases, and in consultation with a
Mercedes-Benz Service Centre, the petrol
may be mixed with the additive recommen-
ded by Mercedes-Ben z(part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.
For further information on "Fuel", see
(Y page 319).
AMG vehicles !
Only refuel using super-grade unleaded
petrol with at least 98 RON/88 MON,
which conforms to European standard EN
228 or equivalent.
You can otherwise impair engine output or
damage the engine.
i If the recommended fuel is not available
and only as a temporary measure, you may
also use premium-grade unleaded petrol,
95 RON/85 MON. This may reduce engine performance and increase fuel consump-
tion. Avoid driving at full throttle.
! In emergencies, and only when the rec-
ommended fuel is not available, you may
also use standard unleaded petrol,
91 RON/82.5 MON.
However, using this fuel results in consid-
erably higher petrol consumption and sig-
nificantly reduced engine performance.
Avoid driving at full throttle.
If no fuel other than regular petrol with
91 RON/82.5 MON or a lower grade is per-
manently available, you should have the
vehicle adapted to run on this fuel by the
local after-sales service centre.
CLS 350 BlueEFFICIENCY !
Only refuel using unleaded, sulphur-free
premium-grade petrol with at least
95 RON/85 MON, which conform stoEuro-
pean standard EN 228 or an equivalent
specification.
You can otherwise impai rengine outpu tor
damage the engine.
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
<10p pm) is used for refuelling, the odours
are reduced. Diesel (EN 590, DIN 51628)
Fuel grade !
Only refuel with diesel that conforms to
European standard EN 590 or German
standard DIN 51628 or equivalent. You can
otherwise impair engine output or damage
the engine.
! Vehicles with diesel particle filters: in
countries outside the EU, only use low sul-
phur Euro diesel with a sulphur conten tof Refuelling
143Driving and parking Z
under 50 ppm
.Otherwise, the emission
control syste mcould be damaged.
! Vehicles without adiesel particle fil-
ter: the engine oil should be changed more
frequently in countries in which diesel with
a higher sulphur conten tis available. More
information about intervals for changing
the engine oil can be obtained from any
Mercedes-Benz Service Centre.
! Using fuel that does not conform to Euro-
pean standard EN 590 or German standard
DIN 51628 can lead to increased wear,
engine damage and damage to the 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 these fuels with diesel fuels and
do not use any special additives. Other-
wise, this can lead to damage to the engine.
This excludes flow improver, see "Low out-
side temperatures".
! Use a filter when adding fuel from a fuel
can. Otherwise, the fuel lines and/or the
diesel injection system could be blocked by
particles from the fuel can.
For further information on "Fuel", see
(Y page 319).
Low outside temperatures Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, various climate-dependent low-tem-
perature classes are defined in EN 590. Refu-
elling with diesel fuel which complies with the
climatic specifications of standard EN 590
can help to prevent operating problems. At
exceptionally low temperatures, it is possible that the flow properties of the fuel may be
inadequate. This also applies to fuel that has
not been adapted to suit the climatic condi-
tions, e.g. diesel fuel from warmer regions.
i
Further information about country-spe-
cific fuel properties can be obtained from
oil companies, e.g. at filling stations.
Flow improver Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective-
ness of a flow improver is not guaranteed with
every fuel.
Correct dosage and thorough mixing are deci-
sive factors in ensuring improvement in low-
temperature resistance. Under certain cir-
cumstances, an excessive dosage may
actually decrease low-temperature resist-
ance and should therefore be avoided.F ollow
the manufacturer's dosing instructions.
Mix the additive with the diesel in good time,
before the flow properties of the diesel
become inadequate. Malfunctions can other-
wise only be rectified by heating the entire
fuel system, e.g. by parking the vehicle in a
heated garage.
Observe the information provided by the man-
ufacturer when using a flow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain
further information from any Mercedes-Benz
Service Centre. Refuelling
Fuel filler flap The fuel filler flap is unlocked or locked auto-
matically when you open or close the vehicle
with the key or using KEYLESS-GO.
The fuel filler flap is located to the rear on the
right. The position of the fuel filler cap is dis-
played in the instrument cluster

Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Even small
amounts of the wrong fuel result in damage
to the fuel system and the engine.

Notes on fuel consumption The vehicle will use more fuel than usual in
the following situations:
R at very low temperatures
R in urban traffic
R on short trips
R in mountainous terrain
i Only for certain countries: the respective
current consumption and emission values
of your vehicle can be found in the COC
papers (EC CERTIFICATE OF CONFORM-
ITY). These documents are supplied when
the vehicle is delivered.
The consumption figures for vehicles up to
the EURO 4standard have been deter-
mined in accordance with EU Directive
80/1268/EEC while figures for vehicles
complying with the EURO 5standard or
higher have been determined in accord-
ance with Regulation (EC) No. 715/2007,
in each case based on the currently appli- cable version. Deviations fro
mthese values
may occur under normal operating condi-
tions.
! Do not use any fuel additives, as they can
cause malfunctions and engine damage. 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. Engine oil
Please bear the following in mind The quality of engine oils is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Ben zapproves
engine oils which 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-
Ben zrecommends that you have the oil
change carried out at a Mercedes-Benz
Service Centre. Mercedes-Benza pproval is
indicated on the oil container by the inscrip-
tion "MB Approval" and the corresponding
designation, e.g. MB Approval 229.51.
The table shows which engines oil have been
approved for your vehicle.

Additives
!
Do not use additives in 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.
Engine oil selection is based on the respective
outside temperatures and in accordance with
the SAE classification (viscosity). The table
below shows you which SAE classifications
are to be used. The low-temperature proper-
ties of engine oils can be significantly
impaired during operation due to, for exam-
ple, 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.
