spring and autumn). G
WARNING
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the
particular container. Always open your vehicle’s doors or windows when cleaning
the inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
Always lock away cleaning products and
keep them out of reach of children.
! Follow the care tips. Wash your vehicle
preferably by hand.
While in operation or even while parked,
your vehicle is subjected to varying
external influences, which left unchecked
can attack the paint as well as the vehicle
underbody and lead to permanent damage.
Such damage is caused not only by extreme
and varying climatic conditions, but also
by:
R Air pollution
R Road salt
R Tar
R Gravel and stone chipping
To avoid paint damage, you should
immediately remove:
R Insects
R Bird droppings
R Tree sap, etc.
R Grease and oil
R Brake fluid
R Coolant
R Fuel
R Tar spots
! Failure to remove such dirt
immediately can cause damage to the

WARNING
During vehicle operation, the boiling
point of the brake fluid is continuously
reduced through the absorption of moisture
from the atmosphere. Under extremely
strenuous operating conditions, this
moisture content can lead to the formation
of bubbles in the system, thus reducing the
system’s efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle’s
Maintenance Booklet for replacement
interval.
Only brake fluid approved by smart is
recommended. Any authorized electric
drive smart center will provide you with
additional information. Windshield/rear window washer system
During all seasons:
X Use a windshield washer concentrate
labeled for summer and water for
temperatures above freezing point.
X Use a windshield washer concentrate
labeled for winter and water for
temperatures below freezing point.

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/
antifreeze, 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 approximatel y-35¦ (-37¥) and
corrosion protection.
! Add premixed coolant solution only.
Adding water and MB 325.0
Anticorrosion/Antifreeze separately
from each other, could cause drive system
damage not covered by the smart Limited
Warranty.
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
corrosion 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
solution 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
protection, the solution must be at least
50% anticorrosion/antifreeze (equivalent
to freeze protection to approximately
-35¦
[-37¥]).
If you use a solution that is more than 55%
anticorrosion/antifreeze (freeze
protection to approximately -49 ¦
[(-45¥]), the drive system and battery
temperature will increas edue to the lower
heat transfer capability of the solution.
Therefore, do not use more than this amount
of anticorrosion/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
information 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.

Anticorrosion/antifreeze
Your vehicle contains a number of
aluminum parts. The use of aluminum
components in motor vehicle drive systems
necessitates that anticorrosion/
antifreeze coolant used in such drive
systems be specifically formulated to
protect the aluminum parts.
Failure to use such anticorrosion/
antifreeze coolant will result in a
significantly shortened service life.
Therefore, the following product is
strongly recommended for use in your
vehicle: MB 325.0 Anticorrosion/
Antifreeze agent.
Before the start of the winter season (or
once a year in hot southern regions), you
should have the anticorrosion/antifreeze
concentration checked.
The coolant is also regularly checked each
time you bring your vehicle to an
authorized electric drive smart center for
service.
