WARNING Risk of an accident due to
vapor pockets forming in the brake system
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point is too low,
vapor pockets may form in the brake system
when the brakes are applied hard.
This causes the braking effect to be impaired.
#
Have the brake fluid renewed at the
specified intervals.
Have the brake fluid regularly replaced at a quali-
fied specialist workshop.
Only use a brake fluid approved by Mercedes-
Benz according to MB-Freigabe or MB-Approval
331.0.
