Checking the oil level using the oil dip-
stick Example: vehicles with a petrol engine
Vehicles with a diesel engine (apart from the A 180
CDI BlueEFFICIENCY model with manual transmis-
sion) A 180 CDI BlueEFFICIENCY, manual transmission
X All models apart from the A 180 CDI
BlueEFFICIENCY model with manual
transmission: pull out oil dipstick :.
X A 180 CDI BlueEFFICIENCY model with
manual transmission: undo the oil filler
cap and pull it out together with integrated
oil dipstick :. X
Wipe off oil dipstick :.
X Slowly slide oil dipstick :into the guide
tube to the stop, and take it out again.
If the level is between MIN mark =and
MAX mark ;, the oil level is correct.
X If the oil level has dropped to MIN mark =
or below, top up with 1.0 litre of engine oil.
Adding engine oil G
WARNING
If engine oil comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Make sure that engine oil does not spill out
over the filler neck. Allow the engine to cool
down and thoroughly clean the components
that have come into contact with engine oil
before you start the engine. H
Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment.
! Only use engine oils and oil filters that
have been approved for vehicles with a ser-
vice system. You can obtain a list of the
engine oils and oil filters tested and
approved in accordance with the
Mercedes-Benz Specifications for Service
Products at any Mercedes-Benz Service
Centre.
Damage to the engine or exhaust system is caused by the following:
R using engine oils and oil filters that have
not been specifically approved for the
service system
R changing the engine oil and oil filter after
missing the change interval required by
the service system
R using engine oil additives
! Do not add too much oil. Topping up with
too much engine oil can result in damage to
the engine or to the catalytic converter.
Have excess engine oil siphoned off. Engine compartment
287Maintenance and care Z

!
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 a diesel particle filter:
in
countries outside the EU, only refuel with
low-sulphur Euro diesel with a sulphur con- tent 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 159).
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 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 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 casebased on the currently applicable version:
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
Deviations from these values may occur
under normal operating conditions. 342

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 338).
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 344
