Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake flu id absorbs moist ure 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 point of the brake fluid
will also decrease considerably and dec rease
bra king performance.
Therefore , the brake fluid must be changed
every
two years . Always use new brake f luid which con-
forms to Federa l Motor Vehicle Standard "FMVSS
116 DOT 4 ".
The bra ke fluid reservoir can be difficult to reach ,
the refore, we recommend that you have the
brake fluid changed by your author ized
Audi
dealer . Your dealer has t he correct tools, t he
right brake fluid and the know-how to do t his for
you.
A WARNING

only in the closed original container out of
the reach of children!
- Brake fai lure can result from old or inappro-
priate brake fluid . Observe these precau-

sure you are using the correct brake fluid.
The correct type of brake fluid is also indi-
cated on the brake fluid reservo ir.
- 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 you r safety. This
could result in an accident.
