Checking and Filling
"' Read the brake fluid level from the brake fluid
reservoir
¢ fig. 187, ¢page 205, fig. 183. The
brake fluid level must be between the "MIN"
and "MAX" markings.
The location of the brake fluid reservoir can be
seen in the engine compartment illustration
c>page205.
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
1111 (U.S. models)/ . (Canadian models)
will come on¢
page 14. Do not continue to oper­
ate the vehicle. The complete brake system
should be thoroughly checked by an authorized
Audi dealer or other qualified facility and the
cause corrected . If the brake fluid level is too
low, the brake warning/indicator light will illumi­
nate. Contact an authorized Audi dealer
immedi­
ately.
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 a pe­
riod 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 fluid which con­
forms to Federal 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 authorized
Audi
dealer.
Your dealer has the correct tools, the
right brake fluid and the know-how to do this for
you.
212
A WARNING
-
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake failure can result from old 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 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 fluid 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.
@ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as well as the special tools re­
quired and the necessary expertise, we rec­
ommend that you have the brake fluid
changed by your authorized Audi dealer .
Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the electro­
lyte level checked by a service facility. The elec­
trolyte level should also be checked each time
the battery is charged ¢
page 214.
Have the battery checked when you take your ve­
hicle in for service. You are well advised to re­
place a battery that is older than S years.

With certain types o f air bag dep loyment, the
battery is disconnected from the vehicle electri­
cal system for safety reasons¢&.
