Brake fluid
Checking brake fluid level
Fig. 192 Engine compartment : cove r on the brake fl uid
reservo ir
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS ~ .&. in Working in the engine compart ­
ment on page 224.
.,. Read the brake fluid level from the brake
fluid reservoir~
fig. 192 , ~ page 226,
fig.
188. The brake fluid leve l must be be­
tween the "MIN" and "MAX" markings .
The location of the brake flu id reservoir can be
seen in the engine compartment illustrat ion
~ page 226.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads . Th is is not cause for alarm.
I f the brake fluid level falls
considerably be­
lo w the "MIN" mark, the brake wa rning/indi­
cator light
1111 (U.S. models)/ . (Canadian
models) will come on~
page 15. Do not con­
tinue to operate the vehicle. The comp lete
brake system should be thoroughly checked
by an authorized Audi dealer or other quali­
fied facility and the ca use corrected. If the
brake fluid level is too low, the brake warning/
indicator light w ill illuminate . Contact an au ­
thorized Audi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the air. If
the water content in the brake fluid is too
high, corrosion in the brake system may result
after a period of time . The boiling point of the
brake fluid will also decrease considerably and
decrease braking pe rformance .
Therefore, the brake fluid must be changed
every two years. Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "FM VSS 116 DOT 4".
The brake fluid reservoir can be diff icult to
reach, therefore, we recommend that you
have the brake fluid changed by your author­
ized
Audi dealer . Your dealer has the correct
tools, the right brake fluid and the know-how
to do this for you.
A WARNING
- Brake fluid is poisonous . It must be stor­
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake fluid. Observe these pre­
cautions:
- Use only brake fluid that meets SA E
specification
J 1703 and conforms to
Federal Motor Vehicle Standard 116.
Always check with your authorized Audi
dealer to make sure you are using the
correct brake fluid. The correct type of
brake flui d is also ind icated on the
brake fluid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
long. This can seriously affect the effi­
c ie ncy of the brakes as well as your
safety. This could result in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

The washer fluid container is marked with the
symbol~ on its cap

C lean water sho uld be used when filling up. If
possible, use soft water to prevent sca ling on
washer jets. Always add a glass cleaner solu­
tion (with frost protection in the winter).
