scalding from hot coo lant by following
these steps.
- Turn
off the engi ne and a llow it to cool
down.
- Protect your face, hands and arms from
escapi ng fl uid and steam by cover ing
the cap with a large, thick rag .
- Turn the cap slowly and very ca refully
i n a cou nte r-clockw ise dir ect ion while
a pply ing lig ht, downwa rd p ress ure on
the top of the cap.
- T o avo id being burned, do no t sp ill an­
tifree ze o r coolan t on t he exh aust sys­
tem or ho t engine parts . Un der certain
conditions, the ethylene glyco l in en­
gine coolant can catch fire .
- Antifree ze is poisono us. Always store an­
tifreeze in its or iginal co ntainer and we ll
o ut o f the reac h of children.
- If you drain the coolant , it must be
caught and safely stored in a p roper con ­
tainer clear ly marked "poison".
(D Note
- Coolant po llutes the env ironment and
could ca use a n engine fire . Excess coo l­
ant wi ll be forced out through the pres ­
sure re lief va lve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added , the correct ratio between water
and antifreeze¢
page 223 must be re­
stored as soon as possib le .
@ For the sake of the environment
Drained coolant should not be re used . Al­
ways dispose of used c oolant while observ­
ing all envir onmental regulations .
Radiator fan
The radiator fan switches on automa tically by
itself
T he radiator fan is driven by the engine via the
V-be lt. The viscous clutch regulates the speed
of the fan according to the temperature of the
coolant .
Checkin g and fillin g 225
An auxiliary electric radiato r fan* sw itches on
and
off depending on coolant temperature
and othe r vehicle ope rat ing con ditions.
After yo u switc h the engi ne off, the aux iliary
f an can con tinue r unning for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself¢ & , if
- t he temperatu re of the engine coo lant rises
due to the heat b uild -up from the en gine in
the engi ne compartment, or
- the engine compartment heats up be cause
the vehicle is parked in intense sunlight.
A WARNING
- To reduce the risk of personal in jury nev­
er touch the radiator fan.
- The a uxiliary electric fan is temperat ure
contro lled and can switch on sud denly
even when the engine is not running.
- The a uxiliary radiator fa n switches on a u­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coo lant temper­
ature drops .
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
qui ck glance.
Fig. 17 3 En gin e compar tment: Cover o n the brak e flu­
i d reservoi r
Before you check anyth ing in the eng ine com­
partment ,
always re ad and heed all WARN­
INGS c::> ,& in Working in the engine compar t-
ment on page 216 . .,..

226 Check ing and filling
• Read the brake fluid level from the brake
fluid reservoir ¢
fig. 173, ¢ page 218,
fig . 169.
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 side ¢
page 218 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .
I f the brake fluid level falls
considerably be­
l ow the "MIN" mark, the brake wa rning/indi­
cator light (U .S . mode ls:
1111 , Canadian
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 corrected . If the
brake fluid level is too low, the brake warn ing/
i ndicato r light w ill illuminate . Contact an au­
thor ized Audi dealer
imm ediat ely .
@ Tips
The brake f luid reservoir is located under­
neath the cove r.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the a ir . If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
b rake fluid w ill also decrease considerably and
decrease braking performance.
Therefore, the brake flu id must be changed
ev ery two years. A lways use new brake fluid
which confo rms to Fede ral Motor Vehicle
S tanda rd "FMVSS 116 DO T 4".
The brake flu id reservoir can be difficult to
reach, therefo re , we recommend that you
have the brake fl uid changed by yo ur au tho r­
ized
Audi d eale r. Your dea le r has the correct tools, the
right brake flu id and the know -how
to do this for you.
A WARNING
'-
- Brake flu id is poisonous. It must be stor-
ed only in the closed or iginal container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake f lu id. Observe these pre­
cautions:
- Use only brake f luid that meets SA E
specifi cation
J 1703 and conforms to
Federa l Motor Vehicle Standard 1 16 .
Always check with your authorized Audi
dealer to make sure yo u are using the
correct brake fluid. The correct type of
brake flu id is also ind icated on the
brake f lu id reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left i n the system too
long . This can se riously affect the effi­
c iency of the brakes as well as your
safety . T his could result in an accident.
W Note
Brake fluid will damage the paint of your
vehicle .
@ For the sake of the environment
Because of the prob lem of proper disposal
of brake fluid as well as the spec ial tools
required and the necessary expertise, we
recommend that you have the brake flu id
changed by your autho rized Aud i deale r.
Battery
General information
Under normal operat ing cond itions, the bat­
tery in your Audi does not need any ma inte­
nance. With
high outside temperatures or
long da ily drives we recommend that you have
the e lectrolyte leve l che cked by an autho rized
A udi dealer or qualified workshop. The elec­
trolyte level should also be checked each time
the battery is charged
¢ page 229. ..,_

256 What do I do now?
@ Tips
-Never use the hexagonal socket in the
handle of the screwdriver to loosen or
tighten the wheel bo lts.
- If a whee l bolt is very tight, you may find
it easier to loosen by carefully pushing
down on the end of the wheel bolt
wrench with
one foot only. As you do so,
hold on to the car to keep your balance
and take care not to slip.
