glance.
Fig. 153 Eng ine compartment: Cover on the brake fluid
r eservoir
Before you check anything in the engine compart
ment,
always read and heed all WARNINGS
¢ A in Working in the engine compartment on
page 177.
., Read the brake fluid level from the brake fluid
reservoir
<=> fig . 153, ¢page 179, fig . 149 . The
brake fluid level must be between the
" MIN"
and "MAX " markings.
The brake fluid reservoir is located at the rear
partition of the engine compartment on the left
side ¢
page 179 .
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 below
the ' 'MIN" mark, the brake warning/indicator
light (USA models:
1111 , Canada models:. )
will come on¢
page 13 . Do not continue to oper
ate the vehicle . The complete brake system
should be thoroughly checked by an authorized
Aud i dealer or qualified workshop and the cause
corrected. If the brake fluid level is too low, the
brake warning/indicator light w ill illuminate.
Contact an author ized Audi dealer
immediately.
(D} Tips
The brake fluid reservoir is located under
neath the cover.

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.
A 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
fi cation
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 fluid .
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.
(D Note
Brake fluid will damage the paint of your vehi-
cle .
