& WARNING Risk of an accident due to
vapor 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,
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
qualified specialist workshop.
Only use brake fluid approved by Mercedes-Benz
according to MB-Freigabe or MB-Approval 331.0.
You can obtain further information on brake fluid

& WARNING ‑ Risk of fire and injury from
antifreeze
If antifreeze comes into contact with hot
component parts in the engine compart‐
ment, it may ignite.
Allow the engine to cool down before
#
adding antifreeze.
Make sure that no antifreeze spills out
#
next to the filler opening.
Thoroughly clean off any antifreeze
#
from component parts before starting
the vehicle.

high outside temperatures.
