W WARNING 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.
