216 Check ing and filling
-If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
-Do not add any type of radiator leak seal­
ant to your vehicle's engine coo lant.
Adding rad iator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty .
- Coolant pollutes the environment and
could cause an engine fire . Excess cool­
ant wil l be forced out through the pres­
s u re re lief valve in the cap when the en­
gine becomes hot.
- If, in an emergency , only water can be
added, the correct ratio between wate r
and antifreeze
c::> page 214 must be re ­
stored as soon as possib le .
@ For the sake of the environment
Dra ined coolant should not be reused. Al­
ways dispose of used coolant while observ­ ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself.
The radiator fan is dr iven by the engine via the
V-be lt . T he viscous clutch regulates the speed
of the fan accord ing to the temperature o f the
coolant .
A n auxiliary e lectr ic radiator fan* switches on
and off depending on coolant temperature
and other vehi cle operating conditions.
After you switch the engine off, the auxiliary
fan can cont inue runn ing for up to 10 minutes
- even with the ignition off.
It can even sw itch
on again later by itself
c::> .&. , if
- the temperature of the engine coolant rises
due to the heat bu ild-up from the eng ine in
the engine compartment, or -
the engine compa rtment heats up because
the vehicle is parked in intense sunlight.
.&_ WARNING .........
- To reduce the risk of personal injury nev­
er touch the radiator fan.
- The auxiliary electric fan is temperature
contro lled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan sw itches on au­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coolant temper ­
ature drops .
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
quick glance.

Before you check anyth ing in the engine com­
partment,
a lwa ys re ad and hee d all WARN­
ING S c::> .&. in Working in the engine compart­
ment on page
207.
~ Read the brake fluid level from the brake
fluid reservoir
c::> fig. 182, c::> page 209,
fig . 177. The brake fluid level must be be­
tween the "MIN" and "MAX" markings .
The brake fluid reservoir is located at the rear
partition of the engine compartment on the
left s ide
c::> page 209.
The fluid level may drop
slightly after some
t ime due to the automatic adjustment of the
brake pads. This is not cause for a larm . .,._

If the brake fluid level falls considerably be ­
l ow the "MIN" mark, the brake warning/indi­
cator light (U.S . mode ls:
1111 . Canad ian
models: .) will come on
¢ page 15. Do not
continue to operate the vehicle. The complete brake system should be thoroughly checked
by an authorized Audi dealer or qualified
workshop and the cause co rrected . If the
b rake fluid level is too low, the brake warn ing/
in dicator light w ill illuminate. Contact an a u­
thor ized Audi dealer
imm ediatel y.
@ Tips
The brake fluid rese rvoir is located unde r­
neath the cover.
Changing brake fluid
Hove the broke fluid changed by on experi­
enced technician .
Brake fluid absorbs moistu re from the a ir. If
the water content in the brake fluid is too
hi gh , corrosion in the b rake system may resul t
after a per iod of t ime . The bo iling po int of t he
b rake fluid w ill also decrease considerably and
decrease braking performance.
Therefore, the brake flu id must be changed
e ver y two year s. Always use new b rake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4".
The brake flu id rese rvoi r ca n be difficult to
r eac h, therefore , we recommend th at yo u
h ave the brake f luid changed by yo ur autho r­
ized
Audi dealer . Your deale r has the correct
too ls, the right brake fluid and the know -how
to do th is for you.
A WARNING
- Brake fluid is po isonous . It must be stor­
ed only in the closed orig inal container
out of the reac h of children!
- Brake fa ilure can result from old or inap­
propr iate brake fluid . Observe these pre­
caut ions:
- Use on ly bra ke fluid that meets SAE
specification
J 1 7 03 and conforms to
Checkin g and fillin g 217
Federa l Moto r Ve hicle Standard 1 16 .
Always check with your authorized Audi
dealer to make sure you are using the correct brake fluid . The correct type of
brake flu id is also ind icated on the
brake f luid rese rvoir .
- The brake fluid must be new . Heavy use
of the brakes ca n cause a vapo r lock if
the b rake fluid is left i n the system too
l ong. This can se riou sly affect the effi­
c iency of the brakes as well as your
safe ty . T his co uld resu lt in an accident.
