Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
quick glance.
Fig. 205 Engine comp artment: cover on the brake fluid
reservoir
Before you check anything in the engine com-
partment, always read and heed all WARN-
INGS 9 &_ in Working in the engine compart-
ment on page 231.
.. Read the brake fluid level from the brake
fluid reservoir 9 fig . 205, q page 233. The
brake flu id leve l must be between the "MIN"
and "MAX" markings.
The location of the brake fluid reservoir can be
seen in the engine compartment illustrat ion
9 page233.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads . This is not cause for alarm.
If the brake fluid level falls
considerably be-
low the "MIN" mark, the brake warning/ind i-
cator light
1111 (U.S. models)/ . (Canadian
models) will come on
q page 14. Do not con-
tinue t o operate the vehicle . The complete
brake system should be thoroughly checked
by an authorized Audi dealer or other quali-
fied fac ility and the cause corrected.
If th e
brake flu id level is too low, the brake wa rning/
indicator light will illuminate. Contact an au-
thorized Audi dealer
immediately.
Changing brake fluid
Have the brake fluid changed by on 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 performance .
Therefore, the brake fluid must be changed
every two years. Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4" .
The brake fluid reservoir can be difficu lt 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 flu id and the know-how
to do this for you .
.&, WARNING
- Brake fluid is poisonous. It must be stor-
ed only in the closed origina l container
out of the reach of children!
- Brake failure can resu lt from old or inap-
propriate brake flu id. Observe these pre-
cautions:
- Use only brake fluid that meets SAE
spec ification
J 1703 and conforms to
Federa l Motor Vehicle Standard 116.
Always check with your authorized Audi
dealer to make sure you are using the
correct brake fluid. The cor rect type of
brake fluid is also indicated 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
lllJ.
