Coolant
Important safety notes
G
WARNING
If antifreeze comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
!
Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
You can find additional notes on the coolant in
the following places:
R
in the Mercedes-Benz Specifications for
Service Products, MB BeVo 310.1
-
on the Internet at
http://bevo.mercedes-benz.com
-
on the Mercedes-Benz BeVo app
R
a qualified specialized 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 replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety notes for ser-
vice products when handling coolant
(Y page 319).
The coolant is a mixture of water and corrosion
inhibitor/antifreeze concentrate. It performs
the following tasks:
R
anti-corrosion protection
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 operation is approximately 266 ‡
(130 †).
The antifreeze concentrate/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
Mercedes-Benz recommends a coolant or cor-
rosion inhibitor/antifreeze 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.

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.
