WARNING
Service products may be poisonous and haz-
ardous to health. There is a risk of injury.
Comply with instructions on the use, storage
and disposal of service products on the labels of the respective original containers. Always
store service products sealed in their original containers. Always keep service products out
of the reach of children.
Brake fluid is hazardous to health. Also
observe the safety notes in the "Service prod-
ucts and capacities" section (Y page 318).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
rubber. If paint, plastic or rubber has come into contact with brake fluid, rinse with
water immediately.
Have the brake fluid renewed every 2 years at
a qualified specialist workshop. Observe the
information on brake fluid in the "Technical
data" section (Y page 324). Check the brake fluid level regularly, e.g.
weekly or when refueling.
Checking the brake fluid level
X Stop your vehicle as far away from traffic as
possible on level ground.
X Switch off the engine.
X Secure the vehicle to prevent it from rolling
away.
X Open the hood (Y page 248).
X Check the brake fluid level.
The brake fluid level is correct if the level is
between the MIN mark and MAX mark on
brake fluid reservoir 0043.
X Close the hood.
! If the brake fluid level in the brake fluid
reservoir has fallen to the MIN mark or
below, check the brake system immedi-
ately for leaks. Also check the thickness of the brake linings. Visit a qualified specialist
workshop immediately.
Do not add brake fluid. This does not cor-
rect the malfunction. 254
