specifications .
The service interva l disp lay in t he instrument
cluster of your vehicle will inform you when it
is time for an oil change . We recommend that
you have your oil changed by an authorized Audi Service Advisor.

-Antifreeze is poisonous . Always store an­
t ifreeze in its or iginal container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
- Coolant pollutes the environment and
could cause an engine fire. Excess coo l­
ant will 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 262 must be re­
stored as soon as possib le.
@ For the sake of the environment
Drained 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 driven by the engine via the
V-belt . The viscous clutch regulates the speed
of the fan accord ing to the temperature of the
coolant .
An auxiliary electric radiator fan* switches on
and off depending on coolant temperature
and other vehicle operating conditions .
After you switch the engine off, the auxilia ry
fan can continue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself¢& , if
- the temperature of the engine coolant rises due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment hea ts up because
the vehicle is parked in intense sunlight .
Checking and fillin g 265
A WARNING
-To reduce the risk of personal injury nev­
er touch the rad iator fan.
- The auxiliary electric fan is temperature
controlled and can switch on suddenly
even when the engine is not running .
- The auxiliary radiator fan switches on au­
tomatically when the engine coolant reaches a certain temperature and will
continue to run until the coo lant temper­
ature drops.

Before you check anything in the eng ine com­
partment ,
always read and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 256.
.,. Read the brake fluid level from the brake
fluid reservoir ¢
fig. 247, ¢ page 258,
fig. 242.
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 eng ine compartment on the
left side ¢
page 258.
The fluid level may drop slightly after some
time due to t he automatic adjustment of the
brake pads. This is not cause for alarm. ..,_

26 6 Ch eck ing and filling
If the brake fluid level falls considerably be­
low the "MIN" mark, the brake warning/indi­
cator light (U .S . mode ls:
11111 , Canadian
models: .) will come on
<=> page 19 and
<=> page 32. Do not continue to operate the ve­
h icle . The complete brake system should be
thoroughly checked by an authorized Aud i
dea ler or qualified workshop and the cause
corrected. If the brake fluid level is too low,
the brake warning/indicator light will illum i­
nate . Contact an authorized Aud i dealer
im­
m ediatel y.
@ Tips
The brake fluid rese rvoir is located unde r­
neath the cove r.
Changing brake fluid
Hove the broke fluid changed by on 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
brake fluid wi ll also decrease considerably and
decrease braking performance.
Therefore, the brake flu id must be changed
e ver y tw o year s. Always use new b rake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 1 16 DO T 4".
The brake flu id reservo ir can be difficult to
reach, therefore, we recommend that you
have the brake f luid changed by you r author­
ized
Audi dea ler. Your dea ler has the correct
too ls, the right brake fluid and the know -how
to do this for you.
A WARNING
- Brake fluid is poisonous . It must be stor­
ed only i n the closed orig inal container
o ut of the reach of children!
- Brake fa ilure can result from old or inap­
propriate b rake fluid. Observe these pre­
caut ions: -
Use only brake fluid that meets SAE
specification
J 1703 and conforms to
Federa l 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 f lu id is also ind icated on the
brake flu id reservoir.
- T he brake fluid must be new. Heavy use
of the bra kes ca n cause a vapo r lock if
the b rake fluid is left in the system too
l ong . This can seriously affect the effi ­
c iency of the brakes as well as your
safety. This co uld resu lt in an accident.
(D Note
Bra ke fluid will damage the paint of you r
vehicle .
(® For the sake of the environment
Because of the p rob lem of p roper disposal
of b ra ke fluid as well as the spec ial too ls
r equired and the necessary expertise, we
re commend that yo u have the brake fluid
changed by yo ur authorized Aud i dea ler.
Battery
General information
U nder normal ope rat ing cond itions , the bat­
tery in yo ur Audi does not need any ma inte­
nance. With
high o utside tempe ra tur es or
l ong dai ly drives we recommend that you have
the e lectrolyte level checked by an authorized
Audi dealer or qualif ied workshop. The elec­
trolyte level should also be checked each time
the battery is charged
<=> page 268.
Have the battery checked when yo u take your
vehicle in for service. You are well advised to replace a battery that is o lder than 5 years .
With certain types of airbag deployment, the battery is disconnected from the veh icle elec­
trical system for safety reasons<=>.&

Tires and wheels
Tires
General notes
Tires may be the least appreci­
ated and most abused parts of
a motor vehicle .
Tires may be the least appreci­
ated and most abused parts of
a motor vehicle. Tires are, how­
ever, one of the most important
parts of a vehicle, particularly
considering the comparatively
small patch of rubber on each
tire that assures that all-impor­
tant contact between you, your
vehicle and the road.
Maintaining the correct tire
pressure, making sure that your
vehicle and its tires do not have
to carry more weight than they can safely handle, avoiding
damage from road hazards and
regularly inspecting tires for
damage including cuts, slashes
irregular wear and overall con­
dition are the most important
things that you can do to help avoid sudden tire failure includ­
ing tread separation and blow-
~ outs.

Avoiding damage
If you have to drive over a curb
or similar obstacle , drive very
slowly and as close as possible
at a right angle to the curb.
Always keep chemicals includ­ ing grease, oil, gasoline and
brake fluid off the tires.
Inspect the t ires regularly for
damage (cuts, cracks or blis­
ters, etc.). Remove any foreign bodies embedded in the treads.
Storing tires
Mark tires when you remove
them to indicate the direction
of rotation. This ensures you to be able to mount them correct­
ly when you reinstall them.
When removed, the wheels or
tires should be stored in a cool, dry and preferably dark place.
Store tires in a vertical position if they are not mounted on
rims, in a horizontal position if
they are mounted on rims.
New tires
New tires have to be broken in
¢ _&. .
The tread depth of new tires
may vary , according to the type .,.

,&_ WARNING
Sudden tire failure can lead
to loss of control, a crash and
serious personal injury!
-Never drive a vehicle when the tread on any tire is worn down to the wear indica­
tors.
-
-Worn tires are a safety haz­
ard, they do not grip well on
wet roads and increase your
risk of "hydroplaning" and
loss of control.
-Always keep chemicals that
can cause tire damage, such
as grease, oil, gasoline and
brake fluid away from tires.
-Tires age even if they are
not being used and can fail
suddenly, especially at high
speeds. Tires that are more
than 6 years old can only be
used in an emergency and
then with special care and
at lower speeds.
-Never mount used tires on
your vehicle if you are not
sure of their "previous histo­
ry." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
