Brake fluid
G WARNIN G
The brak e fluid constantl y absorbs moisture
from th e air. This lower s th e boiling poin t of
th e brak e fluid . If th e boiling poin t of th e brak e
fluid is to o low, vapo r pockets may for m in th e
brak e system when th e brakes are applie d
hard. This would impair braking efficiency.
There is a ris k of an accident.
You should hav e th e brak e fluid renewed at
th e specifie d intervals.
When handlin g brak e fluid , observ e th e impor-
tan t safet y note s on servic e products
( Y
page 388).
The brak e fluid chang e intervals can be foun d in
th e Maintenance Booklet .
Only use brak e fluid approve d by Mercedes-
Benz in accordanc e wit h MB-Freigabe or MB -
Approval 331.0.
Information about approve d brak e fluid can be
obtained at any qualified specialis t workshop or
on th e Internet at

i Have the brake fluid regularly replaced at a
qualified specialist workshop in accordance
with the replacement intervals and the
replacement confirmed in the Maintenance
Booklet.
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.
Further information on coolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact a qualified specialist 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 precautions
for service products when handling coolant
( Y
page 388).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the fol-
lowing tasks: R
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/corrosion inhibitor concentra-
tion 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 an antifreeze/
corrosion inhibito r concentra te in accordance
w
ith 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 corrosion protection.392
