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
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.
! 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.
