adequate antifreeze and corrosion protec-
tion.
! 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 Specifications for
Service Products 310.1, e.g. on the Inter-
net at http://bevo.mercedes-benz.com.
Or contact 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.
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point of
the coolant will be around 266 ‡ (130 †).
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
be at least 50%. This will protect the engine
R
cooling system against freezing down to
approximately -35 ‡ (-37 †).
not exceed 55% (antifreeze protection
R
down to -49 ‡ (-45 †)). Heat will otherwise
not be dissipated as effectively.
If the vehicle has lost coolant, add equal
amounts of water and antifreeze/corrosion
inhibitor. Mercedes-Benz recommends an
anticorrosion/antifreeze which has been
approved for Mercedes-Benz.
! The warranty is only valid if you add an
antifreeze/corrosion inhibitor which has
been approved by Mercedes-Benz and if
the recommended mixture ratio is
observed.
Washer fluid
Important safety notes
G WARNING
Windshield washer concentrate is highly flam-
mable. If it comes into contact with hot com-
ponents in the front compartment, it may
ignite. There is a risk of fire and injury.
Make sure that no windshield washer con-
centrate is spilled next 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 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 309).
Y
At temperatures above freezing:
Fill the washer fluid reservoir with a mixture
X
of water and windshield washer fluid, e.g.
MB SummerFit.
Add 1 part MB SummerFit to 100 parts water.
At temperatures below freezing:
Fill the washer fluid reservoir with a mixture
X
of water and washer fluid, e.g. MB Winter-
Fit.
Adapt the mixing ratio to the outside temper-
ature.
Down to 14 ‡ (Ò10 †): mix 1 part MB Win-

R
terFit to 1 part water.
Down to Ò20.2 ‡ (Ò29 †): mix 2 parts MB
