Brake fluid
G
WARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the
brake fluid is too low, vapor pockets may
form in the brake system when the brakes
are applied hard. This would impair braking
efficiency. There is a risk of an accident.
You should have the brake fluid renewed at
the specified intervals.
! Brake fluid corrodes paint, plastic and rub-
ber. If paint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
When handling, storing and disposing of brake
fluid, please observe the relevant regulations and the important safety notes for service
products (Y page
305).
Over a period of time, the brake fluid absorbs
moisture from the air. This reduces its boiling
point.
Have the brake fluid replaced at specified
intervals by a qualified specialist workshop.
i There is usually a notice in the engine
compartment to remind you when the next
brake fluid change is due.
Use only approved brake fluids that comply
with the Mercedes-Benz Specifications for Ser-
vice Products. Always check for the identifica-
tion DOT 4 plus.
Information about approved brake fluids can
be obtained:

Important safety notes G
WARNING
If antifreeze comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Let the engine cool down before you add
antifreeze. Make sure that antifreeze is not
spilled next to the filler neck. Thoroughly
clean the antifreeze from components
before starting the engine.
! Take care not to spill any coolant on pain-
ted surfaces. You could otherwise damage
the paintwork.
When handling, storing and disposing of cool-
ant and antifreeze, please observe the relevant
regulations and the important safety notes for
operating fluids

(Y page 305).
Coolant additive with corrosion and
antifreeze protection !
Use only approved antifreeze/corrosion
inhibitor that complies with MB Specifica-
tion for Service Products, Sheet Number
325. Using other, non-approved antifreeze/
corrosion inhibitors may cause damage to 310
