When disconnecting and
connecting the battery ...
When you disconnect the vehicle battery
please note the following:
- some data stored in the driver informa-
tion system are erased,
- the clock goes out,
- the factory installed radio locks up,
- the Engine management system,
- the one-touch-u p and one-touch-down
functions of the power windows no lon­
ger work,
- all stored seat positions in the memory*
are erased.
Af teryou reconnect the battery, you must
reset the clock. � page 118.
You also have to reset the Engine manage­
ment system -see "Starter Switch "
�pa ge 113.
You also have to reset the one-touch-up and
one-touch�down feature on power win­
dows -see "Power windows "
�p age 71.
248 You
have also reset the seat memory* -see
"Seats"
� page 81.
The radio must be re-coded with the correct
radio code - see your radio Operating In­
structions.
Replacement battery
A replacement battery must have the same
specifications and dimensions as the origi­
nal equipment battery. Specifications are
listed on the battery housing.
When installing the battery, make sure the
ignition and all electrical consumers are
switched off.
r.Gb. Because of the problem of �proper di
sposal of a battery, we
recommend that you have your au­
thorized Audi Dealer change the
battery for you. Batteries contain
sulfuric acid and lead and must al­
ways be disp osed of properly ob­
serving all environmental regula­
tions. Air
cleaner
A dir ty air cleaner element not only reduces
the engine output and increases fuel con­
sumption considerably but can also cause
premature engine wear.
Normally, it is not necessary to service the
air cleaner more often than recommended
in the Maintenance booklet. If the vehicle is
driven on very dusty roads, the air cleaner
must be serviced more frequently, even dai­
ly.
If your air cleaner element must be
changed mora frequently, we rec­
ommend that you have the air clean­
er serviced by your authorized Audi
Dealer or a qualified workshop.
The air cleaner element must never
be cleaned or soaked with gasoline,
cleaning solvents or oil.

Spark plugs
Spark plugs are replaced during the Audi
scheduled Maintenance Service.
If you have to replace the spark plugs be­
tween the Audi Maintenance services, be
sure to note the following:
• Engine, spark plugs and the ignition sys­
tem are matched to each other. To avoid
faulty operation or engine damage, use only
Original Audi spark plugs. It is especially im­
portant to note the number of electrodes on
the spark plug and the heat value.
• Since spark plug specifications may
change for technical reasons during a model
year, we recommend that you obtain your
spark plugs from an authorized Audi Dealer,
who has the latest information.
Always heed all WARNINGS
on page 232. Belts
Ribbed V-Belt
The radiator fan, hydraulic pump (power
steering), alternator and air conditioner
compressor are driven by one V-belt.
The installed V-belt conforms to the highest
quality requirements. The V-belt adjusts its
own tension.
Replacing of the V-belt should be
performed by your authorized Audi
Dealer or a qualified workshop.
When replacing a belt, it is not sufficient to
use just any belt of the same size. For safe
and reliable operation, use only Genuine
Audi V-belts specially designed for your ve­
hicle. The correct belts can be obta ined at
your authorized Audi Dealer. �W
ARNING
To prevent serious personal inju­
ries stay well clear of the V-belt,
The radiator fan and the V-belt
driven accessories when the en­
gine is running. The V-belt will be
inspected and replaced by your au­
thorized Audi Dealer during a
scheduled Maintenance Service.
Timing belt
• Yo ur engine is equipped with a long last­
ing toothed belt. The belt will be in­
spected and replaced during a scheduled
Maintenance Service.
Always heed all WA RNINGS

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.

VEHICLE
CARE----------------------------------------------------
Tire wear
The original tires on your vehicle have built­
in wear indicators. They are molded into the
bottom of the tread grooves and will appear
as approximately 1h inch (12 mm) bands
when the tire tread depth wears down to
1 /1 6 inches (1.6 mm). Depending on the tire
man ufacturer, there are six to eight wear in­
dicators evenly spaced around the circum­
ference of the tire. Markings on the sides of
the tires (e.g. the letters "TWI" or a triangle)
show the locations of the wear indicators.
254 When the
indicators appear in two or more
adjacent grooves, it is time to replace the
tires. We recommend, however, that you do
not let the tires wear down this far. Worn
tires cannot grip the road surface properly,
and are even less effective on wet roads.
�W ARNING
• Worn tires can lead to a serious
accident.
• lires showing cuts. bruises or
other damage may lead to tire fail­
ure. sudden deflation and loss of
vehicle control.
• Since worn tires do not grip the
road surface properly when the ve­
hicle is driven on wet roads, the ve­
hicle may tend to hydroplane
sooner. I
BBD-2.02.
I
Tire rotation
If the front tires are worn more than rear
tires, then you must rotate the front tires
with the rear tires as shown in the illustra­
tion. By doing this, all tires will have approxi­
mately the same service life.
Tires should always remain on same
side of vehicle.

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.

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.
