Comp ly wit h the impo rtant safety notes for ser-
vice products when han dlin g coolant
( Y
page 377).
The coolant is a mixture of water and ant i-
freeze/corrosion inh ibit or. It performs the fol-
lowin g tasks: R
anti-corrosion protection R
antifreeze protection R
raising the boilin g poin t
If the coolant has antifreeze protection down to
-35 ‡ (-37 †), the boilin g poin t of the coolant
during operation is appr oximately 266 ‡
(130 †).
The antifreeze concentrate /c orrosion inh ibit or
concentration in the engine co olin g system
sho uld: R
be at least 50 %. This will protect the engine
co olin g system against freezing down to
approximate ly -35 ‡ (-37 †).R
not exceed 55% (antifreeze protection down
to -49 ‡[ -45 †]). Otherwise, heat will not be
dissipated as effectively
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in accordance
with MB Specifications for Service Products
310.1.
i When the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and anti-corrosion protection.
i The coolant is checked with every mainte-
nance interval at a qualified specialist work-
shop.

G WARNING
Windshield washer concentrate could ignite if
it comes into contact with hot engine compo-
nents or the exhaust system. There is a risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
