2011 MERCEDES-BENZ C-CLASS SALOON engine

You can recognise service products approved
by Mercedes-Ben
zby the following inscrip-
tion on the containers:
R MB-Freigabe (e.g. MB-Freigabe 229.51)
R MB Approval (e.g. MB Approval 229.51)
Other designations or recommendations
relate to a level of quality or a specification in
accordance with an MB Sheet number (such
as MB 229.5). They have no tnecessarily been
approved by Mercedes-Benz.
You can obtain further information from any
Mercedes-Benz Service Centre. G
WARNING
When handling, storing and disposing of any
service products, please observe the relevant
regulations, as you could otherwise endanger
yourself and others.
Keep service products away from children.
To protec tyour health, do not allow service
products to come into contact with your eyes
or open wounds. See a doctor immediately if
any service product is swallowed. H
Environmental note
Dispose of service products in an environ-
mentally-responsible manner. Fuel
Important safety notes G
WARNING
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine and the auxiliary heating
before refuelling. G
WARNING
Do not come into contact with fuels. It is hazardous to your health if your skin
comes into direct contact with fuels or you
breathe in fuel vapours.

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 outside temperatures
R in urban traffic
R on short journeys

i Only for certain countries: you can find
the curren tconsumption 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 up to and including the EURO
4s tandard, in accordance with EU Direc-
tive 80/1268/ECC
R for vehicles above the EURO 5standard,
in accordance with Regulatio n(EC) No.
715/2007
Deviations fro mthese values may occur
under normal operating conditions.
! 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 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-
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 engine oils have been
approved for your vehicle. Petrol engines MB Approval

Additives
!
Do not use additives in engine oil.T his
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
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.Itis

therefore strongly recommended to observe
regular oil changes using an approved engine
oil with the appropriate SAE classification. Brake fluid
G
WARNING
Ove raperiod 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. Information about approved brake flu-
ids can be obtained from any Mercedes-Benz
Service Centre or on the Internet at
http://bevo.mercedes-benz.com
i There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due. Coolant
Important safety notes The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R
anti-corrosion protection
R antifreeze protection
R raising the boiling point
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
! Only add coolant that has been premixed
with the desired antifreeze protection. The
engine could otherwise be damaged.
Further information on coolants and on fill-
ing can be found in the Mercedes-Benz
Specifications for Service Products, MB
Approval 310.1, e.g. on the Internet at
http://bevo.mercedes-benz.com .You can
also consult a Mercedes-Benz Service
Centre.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
If antifreeze/corrosion inhibitor is present in
the correc tconcentration, the boiling point of
the coolant during operation will be around
130 †.
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
R be at least 50%. This will protec tthe engine
cooling system against freezing down to
around -37 †.
R not exceed 55% (antifreeze protection
down to -45 †); otherwise, heat will not be
dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor- Service products and capacities

! The engine cooling system is filled with
coolant that must be renewed after 15
years, or after 250,000 km at the latest. Vehicle data
