Brake fluid
GWAR NING
Service products may be poisonous and haz-
ardous to health. There isa risk of injury.
Comp ly with instructions on the use, storage
and dispo sal of service products on the labels
of the respective original containers. Always
store service products sealed intheir original
containers. Always keep service products out
of the reach of ch ildren.
GWAR NING
Opening the hood when the engine isover-
heated or when there isa fire inthe engine
compartment could expose you to hot gases
or other service products. There isa risk of
injury.
Let an overheated engine cool downbefore
opening the hood. Ifthere isa fire inthe
engine compartment, keep the hood closed
and contact the fire department.
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool downand
touch only the components describe d in the
foll owin g.
Brake fluid is hazardous to health. Also observe the safety notes under "Service products and
capacities" (
Ypage 304).
GWARNING
The brake fluid constantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. Ifthe boilin g 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.
!If the brake fluid level in the brake fluid res-
ervoir has fallen to the MIN mark or below,
check the brake system immediately for
leaks. Also check the thickness of the brake
linings. Visit a qualified specialist workshop
immediately.
Do not add brake fluid. This does not correct
the malfunction.
!Brake fluid corrodes paint, plastic and rub-
ber. Ifpaint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
Have the brake fluid renewed every two years at a qualified specialist workshop. Observe the
information regarding brake fluid in the "Service
products and capacities" section (
Ypage 309).
