Checking and F ill in g
The brake fluid reservoir is located at the rear
partition of the engine compartment on t he left
side ¢
page 197.
The fl uid level may drop slightly after some time
due to the automatic adjustment of the brake
pads. This is not cause for alarm.
If the b ra ke fluid level fal ls considerably below
the "MIN" mark, the brake warn ing/indi cator
light (U.S. models:
1111 , Canadian models: . )
will come on ¢
page 15. Do not contin ue to oper­
ate the vehicle . The complete brake system
should be thoroughly checked by an author iz ed
Aud i dealer or qualified workshop and the cause
corrected . If the brake fluid level is too low, the
brake warning/ind icator light w ill illuminate .
Contact an authorized Audi dealer
i mmed iately .
{D) Tips
The brake fluid reservoir is located under­
neath the cove r.
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moist ure from the a ir. If the
water content in the brake fluid is too high, cor­ rosion in the brake system may result after a peri­
od of time . The boiling point of the brake flu id
w ill also decrease conside rably and dec rease
b rak ing perfo rmance.
Therefore, the brake flu id must be changed
e ve ry
two year s.
Always use new brake fluid w hich con­
forms to Fede ral Motor Vehicle Standard "FMVSS
1 16 DOT 4".
The brake fluid rese rvoir can be difficult to reach,
therefo re , we recommend that you have the
b rake fluid changed by your author ized
Audi
dealer .
Your dealer has the correct too ls , the
right brake fluid and the know-how to do t his for
you.
A WARNING
- B rake fluid is poisonous. It must be stored
on ly in the closed original container out of
the reach of children!
204
- Brake fail ure can resu lt from o ld or inappro­
priate brake fluid. Observe these precau ­
tions:
- Use only b rake fluid that meets SAE spec i­
f ica tion
J 170 3 and conform s to Federa l
Motor Vehicle Standard 116. Always check
with yo ur autho rized Audi dea le r to make
su re you are using the correct brake fl uid.
The correct type of brake flu id is also ind i­
cated on the brake fluid reservoir.
- The brake fl uid must be new. Heavy use of
the brakes can cause a vapor lock if the
brake f luid 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 acc ident.
(D Note
Brake fluid will damage the paint of your vehi­
cle.
@ For the sake of the env ironment
Because of the prob lem of prope r disposal of
brake fluid as well as the special tools re­
qu ired and the necessary expert ise, we rec­
omme nd that you have the brake flu id
changed by you r autho rized Aud i dea le r.
Battery
, General information
U nder normal operating conditions, the battery
i n your Audi does not need any maintenance.
Wi th
high outside temperatures or long daily
drives we recommend that you have the e lectro ­
lyte level checked by an a uth orized Aud i deale r o r
qualified workshop . The electrolyte leve l should
a lso be checked each time the batte ry is c ha rged
~ page 206.
Have the battery checked when yo u take your ve­
hicle in for service . You a re well adv ised to re­
pla ce a battery that is older tha n 5 years.
With certain types of airbag deployment, the bat ­
te ry is disconnected from the veh icle elect rical
system for safety reasons
¢ & in Repair, care
and disposal of the airbags on page 1 45.

Checking and Filling
-If you get battery acid in your eyes or on
your skin, immediately rinse with cold wa­
ter for several minutes and get medical at­
tention .
- If you should ingest any battery acid, seek
medical attention immediately .
- Do not expose the battery to an open flame, electric sparks or an open light .
- Do not smoke .
- Do not interchange the positive and nega-
tive cables.
- When working on the battery , be sure not to
short-circuit the terminals with tools or oth­
er metal objects . This would cause the bat­
tery to heat up very quickly, which could lead to damage or explosion and personal
injury .
- When a battery is charged, it produces hy­
drogen gas which is explosive and could
cause personal injury.
- Always keep the battery well out of the
reach of children .
- Before work is done on the electrical sys­
tem, disconnect the negative ground cable .
- Before performing any work on the electri­ cal system, switch off the engine and igni­
tion as well as any electrical equipment. The negative cable on the battery must be dis­
connected. If you are just going to replace a
light bulb, then it is enough to switch off
the lights.
- Before disconnecting the battery, switch off
the anti-theft alarm system! Otherwise you
will set off the alarm.
- When disconnecting the battery, first dis­
connect the negative cable and then the
positive cable.
- Before reconnecting the battery, make sure
all electrical consumers are switched off. Re­
connect the positive cable first and then the
negative cable. Never interchange the ca­
bles -this could start a fire!
- Never charge a frozen or a thawed-out bat­
tery. It could explode! If a battery has fro ·
zen, then it must be replaced. A discharged
battery can freeze over at 32°F (0°C).
- Make sure the vent hose is always attached
to the opening on the side of the battery .
206
-Never use batteries which are damaged.
There is the danger of an explosion! Always
replace a damaged battery.
A WARNING
California Proposition 65 Warning:
- Battery posts, terminals and related acces­
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive problems .
Wash hands after handling .
(D Note
- Do not disconnect the vehicle battery when
the ignition is switched on or when the en­
gine is running, otherwise, you will damage
electronic components in the electrical sys­
tem .
-If your vehicle is going to stand for a long
period of time without being driven, protect
the battery from "freezing", otherwise it
will be damaged and will then have to be re­
placed .
Battery charging
Starting the engine requires a well charged bat­
tery.
