Notes on brake fluid
Observe the notes on operating fluids
( page 767).
/
& WARNING Risk of an accident due to
vapour pockets forming in the brake sys-
tem
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,
vapour pockets may form in the brake system
when the brakes are applied hard.
This impairs the braking effect.
ohne
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.

▌Notes on coolant

& WARNING Risk of fire‑ and injury from
antifreeze
If antifreeze comes into contact with hot com-
ponent parts in the engine compartment, it
may ignite.
Allow the drive system to cool down
#
before you top up the antifreeze.
