!
Alway suseasuitabl ecoolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engin ecooling system is not
sufficiently protected from corrosion and
overheating.
! The engin ecooling system is filled with
coolant, which must be renewed after
15 years or after 250,000 kilometres at the
latest.
The coolant is amixtur eofw ater and anti-
freeze/corrosio ninhibitor. It performs the
following tasks:
R anti-corrosio nprotection
R antifreeze protection
R raising th eboiling point
If antifreeze/ corrosion inhibitor is presen tin
the correct concentration, the boil ingp oint of
the coolant during operation will be approx-
imately 13 0†.
The antifreeze/ corrosion inhibitor concentra-
tion in the engin ecooling system should:
R be at least 50%. This will protect the engine
coolin gsystem against freezing down to
approximatel y-37 †.
R not exceed 55% (antifreeze protection
down to -45 †). Hea twill otherwise not be
dissipated as effectively.
If the vehicle has lost coolant, top it up with
equa lamounts of water and antifreeze/cor-
rosio ninhibitor. Mercedes-Benz recom-
mends an antifreeze/corrosion inhibito rcon-
cen trate in accordance with MB Specifica-
tions for Service Products 310.1.
The coolant is checked at every maintenance
interval at aqualified special istworkshop.
i When the vehicle is first delivered ,itisfil-
led with acoolant mixtur ethat ensures
adequate antifreeze and corrosion protec-
tion. Windscreen washe

Important safety notes G
WARNING
Windscreen washer concentrat eishighly
flammable. If it comes into contact with hot
engine component sorthe exhaust system it
coul dignite. There is arisk of fire and injury.
Make sure that no windscreen washer con-
centrate is spille dnext to 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 damage the plastic lenses of the
headlamps.
! 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 amixture
of water and washer fluid, e.g. MB Sum-
merFit.
Mix 1part MB SummerFit to 100 parts water.
At temperatures below freezing:
X Fill the washe rfluid reservoir with amixture
of water and washer fluid, e.g. MB Winter-
Fit.
Adapt the mixin gratio to the outside temper-
ature.
R Down to Ò10 †: mix 1part MB WinterFit to
2p arts water.
R Down to Ò20 †: mix 1part MB WinterFit to
1p art water.
R Down to Ò29 †: mix 2parts MB WinterFit
to 1p art water.
i Add washe rfluid concentrate, e.g. MB
SummerFit or MB WinterFit, to the washer
fluid all year round. 430
