Working in the engine compartment
Be especially ca reful whenever you work in
the engine compartment.
Whenever you must perform any work in the
engine compartment, for example checking
and filling different fluid s, there is a ri sk of
injury , burns and accidents . To prevent per
sonal injury always observe the following
WARNINGS. The engine compartment of any
vehicle is a hazardous area

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

@ For the sake of the environment
Drained coolant should not be re used . Al
ways dispose of used c oolant while observ

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 221
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

Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
qui ck glance.

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 212 . .,..
222 Check ing and filling
• Read the brake fluid leve l from the brake
fluid reservoir ¢
fig. 179, ¢ fig. 175. The
brake f lu id leve l must be between the "MIN"
and "MAX" markings.
The brake fluid reservoir is located at the rear partition of the engine compartment on the
left side ¢
page 214 .
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 b rake war ning/
i ndicato r light w ill illuminate . Contact an au
thor ized Audi dealer
imm ediately .
@ Tips
The brake f lu id reservoir is located unde r
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
dec rease braking per formance.
Therefore, the brake flu id must be changed
e ver y two ye ars. A lways use new b rake 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
r each, therefo re , we recommend that yo u
have the brake fl uid changed by yo ur au tho r
i z ed
Audi dealer . Your dealer has the co rrec t tools, the
right brake flu id and t he know -how
to do this for you.
A WARNING
'-
- Brake flu id is poisonous. It must be stor-
ed only in the closed or igina l container
out of the reach of children!
- Brake failure can res ult from o ld or inap
propriate brake f lu id. Observe these pre
cautions:
- Use only brake f luid that meets SA E
spe cifi cat ion
J 17 03 and conforms to
Federa l Motor Vehi cle Standard 1 16.
Always chec k with yo ur authorized A udi
dealer to make sure yo u are using the
correct brake fluid. The cor rect 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 pai nt of you r
vehicle .
@ For the sake of the environment
Because of the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
r equired and the necessary expertise, we
r ecommend that yo u have the brake flu id
changed by yo ur autho rized Aud i dea le r.

page 252
and r=> page 254.
After changing a wheel
A wheel change is not complete without the
doing the following.
.. Always store the vehicle tool kit, the jack*,
and the replaced tire in the luggage com
partment
r=> page 127.
.,. Check the tire pressure of the spare tire as
soon as possible .
"' As soon as poss ible, have the
tighteni ng
torqu es
on all wheel bolts checked w ith a
t orque wrenc h. The correct tig hte ning tor

Fig. 194 Sill: posit ion ing t he veh icle jack
The location of the jack point is indicated by
an indentat io n on the underside of the vehicle
~fig.193 .
• Activate the parking brake to prevent the
vehicle from rolling unintentionally.
• Move the
selector lever to position P.
• Find the marking (imprint) on the sill that
is nearest the wheel that will be changed
¢ fig. 193. Behind the marking, there is a
lifting point on the sill for the vehicle jack.
• Turn the
vehicle jack located under the lift
ing point on the si ll to raise the jack until
the jaw
Q fig . 194 @ covers the notch on
the vehicle¢ &¢(D .
• Align the vehicle jack so the jaw@ covers
the notch and the base p late @ is flat on
the floor . The base plate@ must be
vertical
under the lifting point @. •
Insta ll the rod on the vehicle jack: Insert
the rod into the opening on the handwheel.
Turn the rod left or r ight to secure it.
• Continue raising the jack with the rod unti l
the wheel lifts off the ground slightly.
Position the vehicle jack
only under the desig
nated lifting points on the si ll
¢fig. 193.
There is exactly one location for each wheel.
The jack must not be positioned at any other location ¢ ,& ¢Ci) .
Soft ground under the jack can cause the ve
hicle to slip off the jack. Always place the jack
on firm ground. Use a flat, stable support if
necessary. Use a non -slip surface such as a
rubber mat on a
slippery surface such as tile .
.&, WARNING
-You or your passengers could be inju red
while changing a wheel if you do not fo l
low these safety precautions:
- Position the vehicle jack on ly at the
designated lifting points and align the
jack. Otherw ise, the vehicle jack could
slip and cause an injury if it does not
have sufficient hold on the vehicle.
-A soft or unstable surface under the jack may cause the vehicle to slip off
the jack. Always provide a firm base for
the jack on the ground. If ne cessa ry,
us e a sturdy board under the jack.
- On hard, slippery su rface (such as tiles)
u se a rubber mat or similar to prevent
the jack from slipping.
- To help prevent injury to yourself and
your passengers:
- Do not raise the vehicle until you are
sure the jack is securely engaged.
- Passengers must not remain in the ve
hicle when it is jacked up.
- Make sure that passengers wait in a
safe place away from the veh icle and
well away from t he road and traffic.
- Make sure jack position is correct, ad
ju st as necessary and then continue to
raise the jack. .,_
CD Note
Do not lift the vehicle by the sill. Position
the vehicle jack only at the designated lift
ing points on the sill. Otherwise , your vehi
