WARNING
If antifreeze comes int ocontact with hot
component sinthe engin ecompartment ,it
may ignite. There is arisk of fire and injury.
Let the engin ecool down before you add
antifreeze .Make sure that antifreeze is not
spilled nex ttothe filler neck.T horoughly
clean the antifreeze from components before
startingt he engine.
! Only add coolant that has been premixed
with the desired antifreezep rotection. You
coul dotherwise 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
Internet at
http://bevo.mercedes-benz.com .Or
contact aqualified specialist workshop.
! Always use asuitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosio nand
overheating.
i Have the coolant regularl yreplaced 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
(Y
page3 47).
The coolant is amixture of water and
antifreeze/corrosion inhibitor. It performs
the following tasks:
R corrosio nprotection
R antifreeze protection
R raising the boiling point
If the coolant has antifreeze protection down
to -35 ‡(-37 †), the boiling point of the
coolant during operatio nisapproximately
266 ‡(130 †).
The antifreeze/corrosion inhibitor
concentration in the engine cooling system
should:
R be at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡(-37 †).
R not exceed 55% (antifreeze protection
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.
i When the vehicle is first delivered, it is
filled with acoolant mixture that ensures
adequate antifreeze and corrosion
protection.
i The coolant is checked with every
maintenance interval at aqualified
specialist workshop. Service products and filling capacities
