Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB Specifications for
Service Products 310.1, e.g. on the Inter-
net 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
replacement confirmed in the Service
Booklet.
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It is responsible
for the following:
R
anti-corrosion protection
R
antifreeze protection
R
raising the boiling point
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point of
the coolant during operation will be approx-
imately 130 †.
The antifreeze/corrosion inhibitor concentra-
tion 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
dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in accord-
ance with
MB Specifications for Service Products 310.1.
i
When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
i
The coolant is checked at every mainte-
nance interval at a qualified specialist
workshop.
Windscreen washer system
Important safety notes
G
WARNING
Windscreen washer concentrate is highly
flammable. If it comes into contact with hot
engine components or the exhaust system it
could ignite. There is a risk of fire and injury.
Make sure that no windscreen washer con-
centrate is spilled next to the filler neck.
!
Do not use distilled or de-ionised water in
the washer fluid reservoir. Otherwise, the
level sensor may be damaged.
!
Only the washer fluids SummerFit and
WinterFit can be mixed. Otherwise, the
spraying nozzles could become blocked.
At temperatures above freezing:
X
Fill the washer fluid reservoir with a mixture
of water and washer fluid, e.g. MB Sum-
merFit.
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 Winter-
Fit.
Adapt the mixing ratio to the outside temper-
ature.
R
Down to
Ò
10 †: mix 1 part MB WinterFit to
2 parts water.
R
Down to
Ò
20 †: mix 1 part MB WinterFit to
1 part water.
R
Down to
Ò
29 †: mix 2 parts MB WinterFit
to 1 part water.
i
Add washer fluid concentrate, e.g. MB
SummerFit or MB WinterFit, to the washer
fluid all year round.
