Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor-
rosion in the brake system may result after ape-
riod of time . The boiling po int of the brake fluid
will a lso decrease considerably and decrease
braking performance.
Therefore , the brake fluid must be changed every
two years . Always use new brake fluid which con-
forms to Feder-al Motor Vehicle Standard "FMVSS
116 DOT 4 ".
The brake fluid reservoir can be difficult 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.

WARNING
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake fai lure can result from o ld or inappro-
priate brake fluid . Observe these precau-
tions:
- Use only brake fluid that meets SAE speci-
fication
J
1703 and conforms to Federal
Motor Veh icle Standard 116. Always check
with your authorized Audi dealer to make
sure you are using the correct brake f luid .
The correct type of brake f luid is also indi-
cated 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 efficiency of
the brakes as well as your safety. This
could result in an accident.
