WARNING
Windshield washer concentrate is highly
flammable. Fire, naked flames and smoking
are prohibited when windshield washer
concentrate is being handled. Coolants
The battery and drive system coolant is a
mixture of water and anticorrosion/anti-
freeze, which provides:
R Corrosion protection
R Freeze protection
R Boiling protection (by increasing the
boiling point)
The cooling system was filled at the factory
with a coolant providing freeze protection
to approximately -35¦ (-37¥) and cor-
rosion protection.
! Add premixed coolant solution only.
Adding water and MB 325.0 Anticorro-
sion/Antifreeze separately from each
other, could cause drive system damage
not covered by the smart Limited War-
ranty.
If the antifreeze mixture is effective to
-35¦ (-37¥), the boiling point of the
coolant in the pressurized cooling system
is reached at approximately 266¦
(130¥ ).
The coolant solution must be used year
round, even in countries which have high
temperatures to provide the necessary cor-
rosion protection and increase boil‑over
protection. Refer to Maintenance/ Service
Booklet for replacement interval.
Coolant system design and coolant used
determine the replacement interval. The
replacement interval published in the
Maintenance booklet is only applicable if
MB 325.0 Anticorrosion/Antifreeze solu-
tion or other smart approved products of
equal specification are used to renew the coolant concentration or bring it back up
to the proper level.
For information on other smart approved
products of equal specification, contact an
authorized electric drive smart center.
To provide important corrosion protec-
tion, the solution must be at least 50% anti-
corrosion/antifreeze (equivalent to freeze
protection to approximately -35¦
[-37¥]).
If you use a solution that is more than 55%
anticorrosion/antifreeze (freeze protec-
tion to approximately -49
¦[(-45 ¥]), the
drive system and battery temperature will
increase due to the lower heat transfer
capability of the solution. Therefore, do
not use more than this amount of anticor-
rosion/antifreeze.
If the coolant level is low, water and
MB 325.0 Anticorrosion/Antifreeze should
be used to bring it up to the proper level
(have cooling system checked for signs of
leakage). Please make sure the mixture is
in accordance with label instructions.
Always use anticorrosion/antifreeze that
has been approved by smart. For informa-
tion contact an authorized electric drive
smart center.
The water in the cooling system must meet
minimum requirements, which are usually
satisfied by normal drinking water.
If you are not sure about the water quality,
consult an authorized electric drive smart
center.
