RE-------------------------
Dust and small particles of dirt lodging in the
pores, grain and seams can have an abra­
sive effect and damage the surface and the
seams. If the vehicle is left standing for a
long time in the sun, cover the upholstery or
use the sun blinds to protect the leather
from direct sunlight and prevent fading or
discoloration.
Depending on the amount of use, clean it
occasionally according to the following
instructions. Never use solvents, wax
polish, shoe cream, spot removers
or similar materials.
For normal cleaning of leather -covered
steering wheels, leather seat upholstery,
etc., slightly moisten a cotton or woollen
cloth with water and wipe over the areas af­
fected.

stubborn dirt can be removed using a
mild soap solution (pure liquid soap: two
tablespoons dissolved in 1 quart of water).
It is very important not to let the wa­
ter soak through the leather or pene­
trate into the seams. Then wipe off with
a soft, dry cloth.
In addition to this regular cleaning, it is
worth while treating the leather with a suit­
able leather -care product. This should be
done about twice a year for uphol stery in
normal use. Apply these products very spar­
ingly and follow the manufacturer's direc­
tions.
Safety belts
Keep belts clean! Dirty belts may
not retract properly.
For cleaning, use a mild soap and water
solution. Let belts dry thoroughly and away
from direct sunlight.
Do not allow inertia reel safety belts to re­
tract before they are completely dry. �W
ARNING
• Any thing that might damage
your safety balta could mean that
you and your passengers would
not be adequately protected in an
accident.
• Do not use chemical cleaning
agents, bleach or dyes. They have
corrosive properties which weak­

• Moisture and ice on brakes may
affect braking efficiency. Test the
brakes carefully after each vehicle
wash.
The engine compartment and transmission
have been corrosion protected at the facto­
ry.
Remove leaves from the plenum panel in
front of the windshield under the engine
hood. This prevents the water drain holes
from becoming blocked, and it prevents de­
bris from entering the vehicle interior
throug h the heating and ventilation ducts. Good
anti-corrosion treatment is very im­
porta nt, particularly in the winter. If the ve­
hicle is frequently driven on salted roads,
the entire engine compartment and plenum
panel should be thor oughly cleaned at the
end of winter and retreated to prevent salt
damage. At the same time, the underside of
the vehicle should be washed as well.

Radiator
fan
The radiator fan is driven by the engine via
the V-belt. The viscous clutch regulates the
speed of the fan according to the tempera­
ture of the coolant.
An auxiliary electric radiator fan switches on

• Always use extreme caution to
prevent clothing. jewelry, or long
hair from getting caught in the en­
gine driven radiator fan, V-belt or
other moving parts.
• Never touch the auxiliary elec­
tric radiator fan. The fan can
switch on suddenly and injure you.
Always heed all WA RNINGS
on page 232. Power
steering
Yo ur vehicle is equipped with a Servotro­
nic power steering. The degree of
power assistance is regulated electronically
according to road speed.
The fluid reservoir is in the engine compart­
ment near the windshield washer container.
The correct fluid level in the reserv oir is im­
portant for the proper functioning of power
steer ing.
The power steering fluid level is checked
during the scheduled Maintenance ser­
vices.
If the electronic regulating system is not
working properly, this is most noticeable
when turning the steering wheel at low
speeds (for example when parking) -more
effort will be required than usual. The fault
should be rectified by an Audi Dealer as
soon as possible. VEH
ICLE CARE
Note
• When the engine is running, never hold
the steering wheel turned all the way to the
right or to the left for longer than 15 sec­
onds. The power steering pump will over­
heat the hydraulic fluid if you hold the steer­
ing wheel all the way turned.
This will damage the power steering
system.
Each time the steering wheel is turned all
the way to the right or left when stopped,
you will hear noises caused by the severe
stress placed on the power steering pump.
At the same time, engine idle speed drops.
• If the power steering system
should fail, or if the engine is not
running (for example, while being
towed). you will still be able to steer
the vehicle, however. more effort
will be required.
• If the power steering system should
have a leak, or is not functioning properly,
contact your authorized Audi Dealer imme­
diately.

VEHICLE
CARE-------------------------
Tires I Wheels
Tires are important but often abused parts
of a vehicle. They not only influence comfort
and ride, but perform vital safety functio �s.
This section is intended to provide you w1th
imp ortant information regarding their prop­
er use, care and replacement.
• Be sure to inspect your tires at least ev­
ery 2,000 miles (3 000 kilometres) for wear
and damage.
• Damage to wheels and tires is not always
easy to see. If you believe that a tire or
wheel has been damaged, it is best to have
it replaced as soon as possible. Internal tire
damage can never get better or ': heal" it­
self, it can only get worse over t1me. Tire
damage can lead to tire failure and loss of
vehicle control. See your authonzed Aud1
Dealer for advice and assistance.
• Mark tires before removing them. Re­
mount tires on the same vehicle side be­
cause the rotation direction must stay the
same.
252 •
Store removed tires in a cool, dry and pre­
ferably dark place. Tires which are not on
wheels should be stored standing up.
• New tires may have different tread
depths due to the configuration and des!gn
by the tire manufacturers. When replacing
tires, use ones with matching tread depth.
�W ARNING
• Tires age even if they are not be­
ing used. Tires which are more
than 6 years should be used only in
an emergency and then with cau­
tion.
• Avoid damaging tires and wheel
rims. If you must drive over a curb
or other obstacle, drive slowly and
as nearly as possible at a right
angle. Frequently check tires for
uneven wear and damage. M
WARNIN G continued
• Remove embedded material.
• Replace worn or damaged tires
immediately.
• Replace missing valve dust
caps.
• Keep oil, fuel, brake fluid, etc.
away from tires.
• Keep tires inflated correctly.
New tires
New tires tend to be slippery and cannot of­
ferfull traction until they have been properly
broken in.
�W ARNING
To help avoid loss of control, al­
ways operate a vehicle with new
tires at lower speeds and with spe­
cial caution for the first 300 miles
(480 kilometres).

lira
service life
The service life of your tires depends for the
most part on the following factors:
lire pressure
Requir ed cold tire inflation pressures are
listed on a sticker inside the fuel filler flap or
on the rear passenger's door pillar (right
side) -depending on the model.
�W ARNING
• Incorrect tire pressures can lead
to a serious or fatal accident:
• Incorrect tire pressures cause
increased tire wear and can affect
handling of the vehicle.
• Incorrect pressures can also
lead to sudden tire failure and
deflati on, causing loss of vehicle
contr ol.
c£' Low tire pressures increase fuel
consumption, which is detri­
mental to the environment. Tire
pressures should be checked at least
once a month and always before a long trip.
Tire pressures are very important,
particularly when the vehicle is driv­
en at higher speeds.
If you are going to be driving at higher
speeds (a lot of expressway driving), then it
is rec ommended to increase the tire pres­
sure by 5 psi (0.3 bar).
Always check tire pressures when the tires
are cold. When the tires are warm, the pres­
sure will be highe r. Do not reduce the
pressure of warm tires.
Don't forget to check the spare wheel. The
inflation pressure is marked on the tire side­
wall.
Use an accurate tire pressure gauge when
checking inflation pressures. Never exceed
the maximum tire inflation pressure listed
on the tire sidewall. Cold tire inflation pres­
sure means: the vehicle has been standing
for at least 3 hours or driven for less than
1 mile (1 km).
Do not forget to replace the valve stem caps
after checking tire pressure. VE
HICL E CA RE
Driving habits
Fast cornering, heavy acceleration and hard
braking all increase tire wear.
Wheel balancing
The wheels on new vehicles are balanced.
When driving, however, various conditions
can cause a wheel to become unbalanced.
This may be noticed as vibrations in the
steering.
Since tire imbalance can cause wear on the
steeri ng, suspension and tires, you should
have your wheels re-balanced. A wheel
should always be balanced if a new tire has
been mounted or a tire was repaired.
Incorrect wheel alignment
Incorrect wheel alignment causes exces­
sive and uneven tire wear, impairing the
safety ofth e veh ide. If you notice excessive
tire wear, contact your authorized Audi
Dealer.
253

Only
when tires show unusual wear such as
feather-e dging should they be rotated diag­
� nall y. Yo ur vehicle may be equipped with
trres which have a specified rotation direc­
tion. The rotation direction is identified by
arrow markings on the sides of the tires.
The rotation direction must not be revers ed.
Therefore, these tires cannot be switched
diagonally. If in doubt, discuss any unusual
tire wear with your authorized Audi Dealer's
service department.
After rotation adjust tire pressure and
torque wheel bolts diagonally to 90 tt lb
(120 Nm). Refer to "Changing a wheel" on
page 267 for details. Tire
replacement
Wheels and tires approved by the manu fac­
turer have been specially matched to your
vehicle and contribute greatly to the road­
holding, driving characteristics and safety of
the vehicle.
Make sure that the new tires also meet the
specifications listed on the label located on
the inside of the fuel filler flap or on the driv­
er's door lock jamb.
It's �mporta nt to remember that in spite of
h �vrng the same tire designation, the actual
s1ze of a tire can vary from tire man ufacturer
to tire man ufacturer. Using different tire and
wheel rim combinations can result in re­
duced clearance between the tire and the
vehicle body.
Therefore, never mount tires that
are of a different designation or
have different dimensions from
those of the factory supplied tires
which came equipped on your ve­
hicle. VE
HICLE CARE
• If you must replace tires different from
those which were originally factory supplied
on your vehicle, always use the specific
brands, specifications and dimensions
which were specified by Audi for your ve­
hicle.
Yo ur authorized Audi dealer or Audi Client
Relations have information regarding the
t1res and wheel rims specified for your car,
and can tell you which tires and tire
man ufacturers were approved by the fac­
tory for original equipment installation.
• We recommend that you have your tires
changed by an authorized Audi Dealer, be­
cause they have the special tools and nec­
essary expertis e.
Furthermore, your authorized Audi Dealer
stocks a range of tires and wheels.
• If the spare tire is different from the tires
that you have mounted on your vehicle (for
example winter tires or wide profile tires),
then use the spare tire for a short period of
time only and drive with extra care. Replace
the flat tire with a tire matching the others
on your vehicle as soon as possible.
255

VEH
ICLE CARE----------------------------------------------------
• For safety reasons, tires should be re­
placed in pairs and not individually. The tires
with the deepest tread should always be
mounted on the front wheels.
�W ARNING
It is essential to the safe operation
of your vehicle that you use only
rims and tires that have the same
designation. sizes and types as
those with which your vehicle was
originally equipped.
Using tires and/or wheal rims dif­
ferent from those which originally
came with your vehicle can reduce
the clearance between the wheels
and the vehicle body. The tires
could then rub against the vehicle
body damaging the tire or the ve­
hicle body. or both. and seriously
effect your safety as well as the
safe operation of your vehicle.
256 •
Ve hicles with quattro ® must always
have tires of the same size, construction
and tread type. For details see page 207.
• Never mount used tires if you are not
sure of their previous history.
• Whenever replacing a tubeless tire, al­
ways install a new valve stem. Tire repair
should only be performed by a specialist.
• In the interest of maximum safety and
best all-around vehicle handling, always buy
replacement radial tires that have the same
specifications with regard to tire size, de­
sign, load carrying capacity, speed rating,
tread pattern, tread depth, etc. This also ap­
plies to Audi recommended alternate re­
placement tires. Tire
specifications
�W ARNIN G
Never mix tires of different design
such as steel belted radials with
radial bias belted or bias ply tires
etc. Mixing tire types will adverse­
ly affect road holding and can lead
to loss of vehicle control and per­
sonal injury.
A knowledge of tire designations makes it
easier to choose the correct tires. Radial ply
tires have the following designations:
e.g. 225 /55 R 17 97 H
225 lire width in mm
55 Heig ht/width ratio in %
R lire construction: Radial
17 Rim diameter in inches
97 Load rating code
H Speed rating code letter

VEHICLE CA
RE--------------------------
The manufacturing date on the tire
side wall (possibly only on the inside of the
wheel):
DOT ... 12 00 ... means that the tire was
produced in the 12th week of 2000.
Tire strength and performance decline with
age -even if the tires are not used. Tire
manufacturers caution that a tire more than
six years old cannot be expected to perform
reliably and safely even in normal use.
�W ARNING
Old tires can fail in use, causing
loss of vehicle control and person­
al injury.
Replace tires after six years re­
gardless of tread wear. Always re­
duce speed and drive cautiously if
you must use an old tire in an emer­
gency. Replace the tire as soon as
possible.
258 Uniform
Tire Quality Grading
Quality grades can be found where applica­
ble on the tire side wall between tread,
shoulder and maximum section width. For
example:
Treadwear 200, Traction AA, Tem­
perature A.
All passenger car tires must conform to
Federal Safety Requirements in addition to
these grades.
Tr eadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when
tested under controlled conditions on a spe­
cified government test course. For exam­
ple, a tire
Qraded 15
0 would wear one and
one half (1112) times as well on the govern­
ment course as a tire graded 1 00. The rei a·
tive perfo rmance of tires depends upon the
actual conditions of their use, however, and
may depart significantly from the norm due
to variations in driving habits, service prac­
tices and differences in road characteristics
and climate. Tra
ction
The traction grades, from highest to lowest,
are AA, A, Band C. Those grades represent
the tire's ability to stop on wet pave ment as
measured under controlled conditions on
specified government test surfaces of as­
phalt and concrete. A tire marked C may
have poor traction performa nce.
�W ARNING
The traction grade assigned to this
tire is based on straight-ahead
braking traction tests, and does
not include acceleration, corner­
ing, hydr oplaning or peak traction
characteristics.

-------------------------VEHICLE
CARE
Te mperature
The temperature grades are A (the highest),
8, and C, repres enting the tire's resistance to
the generation of heat and its ability to dissi­
pate heat when tested under contro lled con­
ditions on a specified indoor laboratory test
wheel. Sustained high temJ)erature can
cause the material of the tire to degenerate
and reduce tire life, and excessive tempera­
ture can lead to sudden tire failure. The
grade C corres ponds to a level of perfor­
mance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Sta ndard No. 1 09. Grades Band A represent
higher levels of performance on the laborato­
ry test wheel than the minimum required by
law.
�W ARNIN G
The temperature grade for this tire
is est ablished for a tire that is
properly inflated and not over­
loaded. Excessive speed, under­
inflation, or excessive loading, ei­
ther separately or in combination,
can causa heat buildup and pos­
sible tire failure. Wheel
replacement
If you wish to equip your vehicle with tires
or wheels other than those installed at the
factory, please note the following:
• For technical reasons it is not al­
ways possible to use wheels from
other vehicles -under certain condi­
tions not even wheels from the same
vehicle model.
• Wheel rims and wheel bolts are
matched to fit your Audi. When
installing different wheels (for ax­
ample, wheels with winter tires), the
correct wheel bolts with the proper
length and conical shape of the bolt
head must be used. The secure fit of
the wheels and the proper function­
ing of the brake system and safety
are dependent upon this.
• Wheel rims and wheal bolts are
matched to fit your Audi. •
Before you plan on exchanging
steel wheels, light alloy wheals, or
winter tires already mounted on
wheel rims, consult your authorized
Audi Dealer. They have the technical
information necessary to advise you
which wheal rims and wheel bolts
are compatible with the original fac­
tory installations.
1ft WARNING
• Incorrect tire/wheel parts may
cause an accident and personal in­
jury. Such parts will adversely af­
fect the safe operation of your ve­
hicle. Always use tires, wheel rims
and wheel bolts that meat specifi­
cations of the original factory­
installed equipment.
• If wheel trim discs or a front
spoiler are Installed, make sura the
airflow for cooling the brakes is
not obstructed.
