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 223.
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/indicator
light (U.S. models:
1111 , Canadian models: . )
will come on¢
page 18 and ¢ page 28 . Do not
continue to operate the vehicle . The complete
brake system shou ld be thoroughly checked by an
author ized Audi dealer or qualif ied workshop and
the cause corrected. If the brake fluid level is too low, the brake warning/indicator light will illum i
nate. Contact an authorized Aud i dealer
immedi
a tel y.
Changing brake fluid
Have the brake fluid changed by an experienced technician.
Brake flu id abso rbs moisture from the a ir . If the
water content in the brake fluid is too high, cor rosion in the b rake system may result after a pe ri
od of time. The boiling point of the bra ke fluid
will also decrease conside rably and decrease
b ra ki ng per fo rmance .
Therefore, th e brake flu id must be changed
ev ery
tw o years .
Always use new b rake fluid w hich con
forms to Fede ra l Motor Vehicle Standa rd " FMVSS
1 16 DOT 4".
The brake fluid rese rvoir can be difficult to reach,
therefo re, we recommend that yo u have the
b rake fluid changed by your authori zed
Audi
dealer .
Your dealer has the cor rect too ls, the
right brake f luid and the know -how to do t his for
you.
A WARNING
- Brake fluid is po isonous. It must be stored
only in the closed orig inal container out of
the reach of children!
- Brake fai lure can result from old or inappro
pr iate brake fluid . Observe these precau
t ions:
230
- Use only brake fluid that meets SAE spec i
ficat io n
J 1703 and conforms to Federal
Motor Vehicle Sta ndard 116 . Always check
with your aut horized Aud i dea ler to make
su re you are using the correct brake fl uid .
The co rrect type of brake f lu id is also ind i
cated on t he b rake fluid reservoir.
- The brake fl uid must be new. Heavy use of
the b rakes can cause a vapor lock if the
brake fluid is left in t he system too long.
This can se riou sly affec t the efficiency of
the b rakes as well as yo ur sa fety. This
could result in an acc ident .
(D Note
Bra ke fluid will damage the pai nt of you r vehi
cle.
@ For the sake of the environment
B ecause of the prob lem of prope r disposal of
b rake fluid as well as the spe cial tools re
q ui red and the necessary ex pert ise, we rec
ommend that you have the brake f lu id
cha nged by yo ur autho rize d Aud i dea le r.

Checking and Filling
-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
z en, then it must be replaced . A discharged
battery can freeze over at 32°F (O°C).
- Make sure the vent hose is always attached
to the opening on the side of the battery .
- Never use batteries which are damaged.
There is the danger of an explosion! Always
replace a damaged battery.
A WARNING
California Proposition 65 Warning:
