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:
be at least 50%. This will protect the engine

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
( page 352).
Y
At temperatures above freezing:
Fill the washer fluid reservoir with a mixture of
X
water and washer fluid, e.g. MB SummerFit.
Mix 1 part MB SummerFit to 100 parts water.
At temperatures below freezing:
Fill the washer fluid reservoir with a mixture of
X
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.
