General notes Depending on your driving style, the vehicle
consumes up to 0.8 litres of oil per 1,000 km.
The oil consumption may be higher than this
when the vehicle is new or if you frequently drive
at high engine speeds.
Depending on the engine, the oil dipstick may be installed at a different location.
When checking the oil level:
R park the vehicle on a level surface
R the engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature.
R if the engine is not at normal operating tem-
perature, e.g. if the engine was only started
briefly, wait approximately 30 minute sbefore
carrying out the measurement

Mercedes-Benz Service Centre, will reset the
ASSYST PLUS service interval display after the
service work has been carried out. You can also
obtain further information on maintenance
work, for example.
Special service requirements The prescribed service interval is based on nor-
mal operation of the vehicle. Service work will
need to be performed more often if the vehicle is
operated under arduous conditions or increased loads, for example:
R Regular city driving with frequent intermedi-
ate stops
R If the vehicle is primarily used to travel short
distances
R For frequent use in mountainous terrain or on
poor road surfaces
R If the engine is often left idling for long periods
R In particularly dusty conditions, or if air-recir-
culation mode is frequently used.
In these or similar operating conditions, have
the interior filter, engine air cleaner, engine oil
and oil filter, for example, changed more fre-
quently. The tyres must be checked more fre-
quently if the vehicle is operated under
increased loads. Further information can be
obtained at a qualified specialist workshop, e.g.
a Mercedes-Benz Service Centre.

Cleaning the exhaust tail pipes
G
WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
! Do not clean the exhaust pipe with acid-
based cleaning agents, such as sanitary
cleanser or wheel cleaner.
! Mercedes-AMG vehicles with black exhaust
pipes: the black-chrome tailpipe finishers
should not be polished with a chrome polish.
They will otherwise lose their black sheen. For optimal care, the finishers should be rubbed
with a lightly oiled cloth after every car wash.
Commercially available engine and care oils
are suitable for this.
For heavier soiling, you can apply a fine paint- work polish with a microfibre cloth. Remove
the excess polish residue after polishing.
Impurities combined with the effects of road grit and corrosive environmental factors may cause
flash rust to form on the surface. You can
restore the original shine of the exhaust pipe by
cleaning it regularly, especially in winter and
after washing the vehicle.
X Clean the exhaust pipe with a care product
tested and approved by Mercedes-Benz.
Cleaning the trailer tow hitch H
Environmental note
Dispose of oily and greasy cloths in an envi-
ronmentally-responsible manner.
! Do not clean the ball coupling with a high-
pressure cleaner. Do not use solvents.
! Please note the care instructions in the
trailer coupling manufacturer's operating
instructions. X
Remove rust, e.g. with a wire brush.
X Remove dirt with a clean, lint-free cloth or a
brush.
X After cleaning, lightly oil or grease ball cou-
pling :.
X Check that the vehicle's trailer tow hitch is
working properly.
i You can also have the maintenance work on
the ball coupling and the trailer tow hitch car-
ried out by a qualified specialist workshop. Interior care

Diesel
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 a risk 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 equivalent quality. Fuel that does not
conform to EN 590 can lead to increased wear
as well as damage to the engine and 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 such fuels with diesel fuel and do
not use any special additives. Otherwise,
engine damage may occur.
! Vehicles with diesel particle filters:
in
countries outside the EU, only use low sulphur
Euro diesel with a sulphur content of under
50 ppm. Otherwise, the emission control sys- tem could be damaged.
! Vehicles without a diesel particle filte
r:
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 quali-
fied 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 station staff.
Information on refuelling (Y page 153).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 specifica-
tions outlined in EN 590. At unusually low out-
side temperatures, it is possible that the flow
characteristics of the diesel fuel could be insuf- ficient. Accordingly, diesel fuel from warmer
areas may not be suitable for operation in colder
climatic conditions.
i Further information on country-specific fuel
properties and fuel types with low-tempera-
ture resistance can be obtained from oil com-
panies, e.g. at filling stations. Engine oil
General notes When handling engine oil, observe the important
safety notes on service products (Y page 327).
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 tech-
nical 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 recom-
mends that you have the oil change carried out
at a qualified specialist workshop. Mercedes-
Benz approval is indicated on the oil container
by the inscription "MB-Freigabe" or "MB- 330
