ARNING Risk of an accident due to
vapour pockets forming in the brake sys-
tem
The brake uid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake uid. If the boiling point is too low,
vapour pockets may form in the brake system
when the brakes are applied hard.
This impairs the braking e ect.
Have the brake uid renewed at the
#
speci ed intervals.
Have the brake uid regularly replaced at a quali-
ed specialist workshop.
Only use a brake uid approved by Mercedes-
Benz according to MB-Freigabe or MB-Approval
331.0.

ARNING Risk of re‑ and injury from
antifreeze
If antifreeze comes into contact with hot com-
ponent parts in the engine compartment, it
may ignite.
Allow the engine to cool down before
#
you top up the antifreeze.
Make sure that no antifreeze spills out
#
next to the ller opening.
Thoroughly clean the antifreeze from
#
component parts before starting the
vehicle.
* N N O O TE TE Damage caused by incorrect cool-
ant
Only use coolant that has been premixed
#
with the required antifreeze protection.

* N N O O TE TE Overheating at high outside temper-
atures
If an inappropriate coolant is used, the engine
cooling system is not su ciently protected
against overheating and corrosion at high out-
side temperatures.
Only use coolant approved for
