Brake fluid
When handling brake fluid, observe the
important safety notes on service products
( page 199).
Y
The brake fluid change intervals can be found
in the Maintenance Booklet.
Only use brake fluid approved by Mercedes-
Benz according to MB Approval 331.0.
Information about approved brake fluid can
be obtained at any qualified specialist work-
shop or on the Internet at
http://bevo.mercedes-benz.com.
i
Have the brake fluid regularly replaced at

Coolant
General notes
!
Only add coolant that has been premixed
with the desired antifreeze protection.
You could otherwise damage the engine.
Further information on coolants can be
found in the Mercedes-Benz Specifications
for Service Products, MB BeVo 310.1, e.g. on
the Internet at
http://bevo.mercedes-benz.com. Or con-
tact a qualified specialist workshop.
!
Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
i
Have the coolant regularly replaced at a
qualified specialist workshop and the
replacement confirmed in the Maintenance
Booklet.
Comply with the important safety precautions
for service products when handling coolant
( page 199).
Y
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
corrosion protection
R
antifreeze protection
R
raising the boiling point
R
Service products and filling capacities
If the coolant has antifreeze protection down
to -35 ‡ (-37 †), the boiling point of the cool-
ant during operation is approximately 266 ‡
(130 †).
The antifreeze/corrosion inhibitor concen-
tration in the engine cooling system should:
be at least 50%. This will protect the engine
R
cooling system against freezing down to
around -13 ‡ (-25 †).
not exceed 50% (antifreeze protection down
R
to -35 ‡ [-37 †]). Otherwise, heat will not be
dissipated 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 discoloration depending
on the mixing ratio does not affect the func-
tion.
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 with every main-
tenance interval at a qualified specialist
workshop.
Windshield washer system
General notes
!
Do not add distilled or de-ionized water
to the washer fluid container. Otherwise,
the level sensor may be damaged.
!
Only MB SummerFit and MB WinterFit
washer fluid should be mixed together. The
spray nozzles may otherwise become
blocked.
When handling washer fluid, observe the
important safety notes on service products
( page 199).
Y
At temperatures above freezing:
Fill the washer fluid reservoir with a mix-
X
ture of water and windshield washer fluid,
e.g. MB SummerFit.
Add 1 part MB SummerFit to 100 parts water.
