Coolant
Important safety notes
G
WARNING
If antifreeze comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Let the engine cool down before you add
antifreeze. 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

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
replacement confirmed in the Maintenance
Booklet.
Comply with the important safety notes for
service products when handling coolant
(Y page 335).
The coolant is a mixture of water and corro-
sion inhibitor/antifreeze concentrate. It per-
forms 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 cool-
ant 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 fil-
led with a coolant mixture that ensures ade-
quate antifreeze and anti-corrosion protec-
tion.
i
The coolant is checked with every mainte-
nance interval at a qualified specialist work-
shop.

WARNING
Windshield washer concentrate is highly
flammable. If windshield washer concentrate
gets onto hot components of the engine or
the exhaust system, it can ignite. There is a
risk of fire and injury.
Make sure that windshield washer concen-
trate is not spilled in the vicinity of the filler
neck.
