If the brake flu id level falls considerably below the "MIN" mark, the
brake warning/indicator light ( U.S. models:
BRAKE , Canadian mode ls:

operate the vehicle. The complete brake system should be thoro ughly
c he cked by an au thor ized Aud i deale r or q ualified works hop and t he
cause corrected. If the brake fluid level is too low, the brake
w ar ning/ind ic a tor ligh t will illum ina te. Con ta ct a n au thori ze d Audi
dealer
immediately .
rn Tips
The brake fluid reservoir is located underneath t he cover. •
Changing brake fluid
Have the brake fluid cha nged b y an experienced tech ni­
c ia n.
Brake fluid absorbs mo isture from the a ir . If the water content in the
bra ke fl uid i s too hig h, cor ros io n in th e bra ke system may res ult afte r
a period of time. The boiling po int of the brake fluid will also decrease
cons iderab ly and decrease brak ing perfo rmance .
Th erefo re, th e brake fl uid must be changed
every two years . Always
use new bra ke fluid w hich conforms to Federal Motor Vehicle Stan ­
dard "F MVSS 1 16 DO T 4".
The brake flu id reservoir can be diffic ult to reac h, therefore, we
recommend that you have the bra ke fluid c hanged by your author ized
Audi dealer . Your dealer has the correct tools, the right brake flu id
and the know -how to do t his for you .
LJ}. WARNING
• Brake fluid is poisonou s. It mu st be stored only in the closed
original containe r out of the reach of children!
& WARNING (co ntinued )
• Brake failure can result from old or inappropriate brake fluid.
Observe these precaution s:
- Use only brake fluid that meets SAE specification
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 indicated on the brake fluid reservo ir.
- The brake flu id 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.
0 Note
Bra ke fluid will damage the paint of your veh icle.
For the sake of the environment
Because of the prob lem of proper disposal of brake fl uid as well as
t he s pecial tool s required a nd the nece ssary ex pert ise, we recom ­
mend that you have t he brake f lu id changed by your authorized Audi
de aler. •
