Resetting the ASSYST PLUS service
interval display !
If the ASSYST PLUS service interval display
has been inadvertently reset, this setting can
be corrected at a qualified specialist work-
shop.
Have service work carried out as described in the Service Booklet. This may otherwise lead
to increased wear and damage to the major
assemblies or the vehicle.
A qualified specialist workshop, e.g. a
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.
Driving abroad An extensive Mercedes-Benz Service network is
also available in other countries. You can obtain further information from any Mercedes-Benz
Service Centre. ASSYST PLUS

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 filter:
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 164).
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 352).
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 engine oil change car- ried out at a qualified specialist workshop.
Mercedes-Benz approval is indicated on the oil
container by the inscription "MB-Freigabe" or
"MB-Approval" and the corresponding designa-
tion, e.g. MB-Freigabe or MB-Approval 229.51.
You can call up an overview of approved engine
oils on the Internet at
http://bevo.mercedes-benz.com by entering
the designation, e.g. 229.5.
The table shows which engine oils have been
approved for your vehicle.

Additives
!
Do not use any additives with the engine oil.
This could damage the engine. 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 impor-
tant safety notes on service products
(Y page 352).
The brake fluid change intervals can be found in the Service Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB-Freigabe or MB-Approval
331.0.
Information about approved brake fluid can be
obtained at any qualified specialist workshop or on the Internet at
http://bevo.mercedes-benz.co m.
i Have the brake fluid regularly replaced at a
qualified specialist workshop and the replace- ment confirmed in the Service Booklet. 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
clean the antifreeze from components before
starting the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be found in the Mercedes-Benz Specifications for Ser-
vice Products, MB Specifications for Service 356
Service products and capacitiesTechnical data
Products 310.1, e.g. on the Internet at
http://bevo.mercedes-benz.com. Or contact a qualified specialist workshop.
! 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.
i Have the coolant regularly replaced at a
qualified specialist workshop and the replace- ment confirmed in the Service Booklet.
Comply with the important safety precautions
for service products when handling coolant
(Y page 352).
The coolant is a mixture of water and corrosion
inhibitor/antifreeze concentrate. It is responsi-
ble for the following:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
If corrosion inhibitor/antifreeze concentrate is
present in the correct concentration, the boiling
point of the coolant during operation will be
approximately 130 †.
The antifreeze concentrate/corrosion inhibitor
concentration in the engine cooling system
should:
R be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -37 †.
R not exceed 55% (antifreeze protection down
to -45 †). Heat will otherwise not be dissipa- ted as effectively.
Mercedes-Benz recommends a coolant or cor-
rosion inhibitor/antifreeze concentrate in
accordance with
MB Specifications for Service Products 310.1.
i When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and corrosion protection.
i The coolant is checked at every mainte-
nance interval at a qualified specialist work-
shop. Windscreen washer system
Important safety notes G
WARNING
If windscreen washer concentrate comes into contact with hot components of the engine or
the exhaust system, it can ignite. There is a
risk of fire and injury.
Make sure the windscreen washer concen-
trate does not come into contact with the filler neck.
! Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or MB
WinterFit. Unsuitable washer fluid could dam-
age the plastic lenses of the headlamps.
! Only the washer fluids SummerFit and Win-
terFit can be mixed. Otherwise, the spraying
nozzles could become blocked.
Do not use distilled or de-ionised water. Other-
wise, the level sensor may give a false reading.
When handling washer fluid, observe the impor- tant safety notes on service products
(Y page 352).
At temperatures above freezing:
X Fill the washer fluid reservoir with a mixture of
water and washer fluid, e.g. MB SummerFit.
Mix 1 part MB SummerFit to 100 parts water.
At temperatures below freezing:
X Fill the washer fluid reservoir with a mixture of
water and washer fluid, e.g. MB WinterFit.
For the correct mixing ratio, refer to the infor- mation on the antifreeze reservoir.
i Add washer fluid concentrate, e.g. MB Sum-
merFit or MB WinterFit, to the washer fluid all
year round. Service products and capacities
