i
Have the coolant regularly replaced at a
qualified specialist workshop and the
replacement confirmed in the Service
Booklet.
Comply with the important safety precautions
for service products when handling coolant
(
Y
page 217).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R
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 is
approximately 130
†
.
The antifreeze/corrosion inhibitor concen-
tration in the engine cooling system should:
R
be at least 50%. This will protect the engine
cooling system against freezing down to
approximately
-
25
†
.
R
not exceed 50% (antifreeze protection down
to
-
37
†
). Heat will otherwise not be dis-
sipated as effectively.
smart recommends an antifreeze/corrosion
inhibitor concentrate in accordance with MB
Specifications for Operating Fluids 310.1 or
325.6.
Antifreeze/corrosion inhibitor concentrate
in accordance with MB Specifications for
Operating Fluids 310.1 and 325.6 can be mixed
together. An orange discolouration depend-
ing on the mixing ratio does not affect the
function.
i
When the vehicle is first delivered, it is
filled 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
General notes
!
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.
When handling washer fluid, observe the
important safety notes on service products
(
Y page 217).
At temperatures above freezing:
X
Fill the washer fluid reservoir with a mix-
ture 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 mix-
ture of water and washer fluid, e.g. MB Win-
terFit.
The correct mixing ratio can be taken from
the information on the antifreeze protec-
tion container.
i
Add washer fluid concentrate, e.g. MB
SummerFit or MB WinterFit, to the washer
fluid all year round.
