Do not fi ll coo lant above the "MAX" mark . Excess coolant will be
f o rced ou t through the pressure re lief va lve in the cap when the
engine becomes hot.
& WARNING
• The cooling system is under pressure and can get very hot .
Redu ce the risk of scalding from hot coolant by following these
steps .
- Turn off the engine and allow it to cool down.
- Protect your face , hands and arms from e scaping fluid and
steam by covering the cap with a large, thick rag.
- Turn the cap slowly and very carefully in a counter -clockwise
direction while applying light , downward pressure on the top
of the cap.
- To avoid being burned , do not spill antifreeze or coolant on
the e xhaust system o r hot engine parts . Under certain condi ­
tions , the ethylene glycol in engine coolant can catch fire.
• Antifreeze is poisonous . Always store antifreeze in its original
container and well out of the rea ch of children.
• If you drain the coolant , it must be caught and safely stored in
a proper container clearly marked "poison".

Radiator fan
The radiator fa n switches on au toma tically by i tself.
T he e lectric radiator fan is control led bythermoswitches that switch
on and off depending on coolan t and engine compar tm ent temper ­
atures .
An auxiliary e lectric radiator fan * switches on and off depending on
coolant temperature and other vehicle operation conditions.
After switching off the engine , the auxiliary fan -even with the igni ­
tio n off -ca n co ntinue runni ng for u p to 10 minutes. It can even
switch on again later by itself=>&, if
• the temperat ure of the engine coolant rises due to the heat
build -up from the engine in the engine compartment, or
• t he engine co mpart men t heats up because the vehicle is parked
in intense sunlight.
& WARNING
• To reduce the risk of personal injury never tou ch the r ad iator
fan .
• The auxiliary electric fan is temperature controlled and can
switch on suddenly even when the engine i s not running .
• The auxiliary radiator fan switches on automatically when the
engine cool ant reache s a certain temperature and will continue to
run until the coolant temperature drop s. •
Brake fluid
Checking brake fluid level

Be fore yo u check anythin g in the e ng ine compar tm ent,
always read and heed all WARNINGS=> & in "Working in
t h e eng ine compartment" on
page 224.
Read t he brake fl uid lev el from t he brake flui d res ervoir .
T he b rak e fluid l eve l must b e between the
"MI N" and
"M AX" markings => fig. 170.
The brake f luid reservoir is located at the rear pa rtit ion of the engine
compartment on the left side=> page 225.
T he fluid leve l may drop slightly after some time due to the auto ­
ma tic adjustment o f the brake pads. Th is is not cause for alarm .
I f the brake flu id leve l falls considerably below the "MIN" mark, the
brake warning/indicator light (U.S . models :
BRAKE, Canadian models:
ID ) will come on=> page 15 and=> page 30. Do not continue to
operate the vehic le . The complete brake system should be thor ­
oughly checked by an au thorized Audi dealer or other qualified
facility and the cause corrected. If the brake fluid leve l is too low, the .,,_

i m medi at ely.•
Changing brake fluid
Have the brake fluid changed by an experienced techni­
cian.
Brake fluid absorbs moisture from the ai r. If the water content in the
brake fluid is too high, corrosion in the brake system may result
after a period of time. The boiling point of the brake fluid wil l also
decrease considerably and decrease braking performance .
Therefore, the brake fluid must be changed
e ver y two years. Always
use new brake fluid which conforms to Federa l Motor Vehicle Stan ­
dard "FMVSS 116 DOT 4" .
The brake fluid reservoir can be difficu lt to reach , therefore, we
recommend that you have the brake fluid changed by your autho­
rized
Audi d ealer. Your dealer has the correct tools, the right brake
fluid and the know-how to do this for you.
& WARNING
• Bra ke fluid i s poisonous . It mu st be stored on ly in the close d
ori ginal container out of the rea ch of children!
• Bra ke fa ilure can result from old or inappropri ate brake fluid .
Observe the se pre caution s:
- Use o nly brake fluid that meets SAE spe cifi ca tion
J 170 3 and
c onform s to Fed era l Moto r Vehic le Sta nda rd 116 . Always c heck
w ith your authori zed Audi de aler to m ake sure you are using
the correct brake fluid. The corr ect type of brake fluid i s als o
indi cated o n the br ake fl uid reser vo ir.
- The br ake flu id mu st be ne w. Hea vy use of the brake s can
c au se a vap or lo ck if the bra ke fluid i s left in the system too
long. Thi s can seriou sly affect the efficienc y of the brake s as
we ll as your safet y. Thi s co uld re su lt in an acci dent .
0 Note
Brake fluid wi ll damage the paint of your vehicle .
<£' For the sake of the environment
Because o f the problem of prope r disposal of brake flu id as we ll as
the special tools required and the necessary expertise, we recom ­
mend that you have the brake fluid changed by your authorized Audi
dea ler. •
