Comply with the important safety precautions
for service products when handling coolant
( page 263).
Y
The coolant is a mixture of water and
antifreeze/corrosion inhibitor. It performs
the following tasks:
corrosion protection
R
antifreeze protection
R
raising the boiling point
R
If the coolant has antifreeze protection down
to -35 ‡ (-37 †), the boiling point of the
coolant during operation is approximately
266 ‡ (130 †).
The antifreeze/corrosion inhibitor
concentration 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 †]). Otherwise, heat
will not be dissipated as effectively.
If the vehicle has lost coolant, add equal
amounts of water and antifreeze/corrosion
inhibitor. Mercedes-Benz recommends an
antifreeze/corrosion inhibitor concentrate in
accordance with MB Specifications for
Service Products 310.1.
The coolant is checked with every
maintenance interval at a qualified specialist
workshop.

When the vehicle is first delivered, it is
filled with a coolant mixture that ensures
adequate antifreeze and corrosion
protection.
Windshield/headlamp cleaning
system
Important safety notes
! 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.
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 windshield washer fluid, e.g.
MB WinterFit.
Adapt the mixing ratio to the outside
temperature.
Down to 14 ‡ (Ò10 †): mix 1 part MB
R
WinterFit to 2 parts water.
Down to Ò4 ‡ (Ò20 †): mix 1 part MB
R
WinterFit to 1 part water.
Down to Ò20.2 ‡ (Ò29 †): mix 2 parts MB
R
WinterFit to 1 part water.
i
Add windshield washer fluid, e.g. MB
SummerFit or MB WinterFit, to the washer
fluid all year round.
