New tires or wheels
Audi recommends having all work
on tires o r wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
knowle dge and are eq uipped with
the requ ired too ls and replace­
ment parts.
.,. New tires do not yet have the
optimum g ripping properties .
Drive carefully and at mode rate
speeds for the first 350 miles
(500 km) with new tires.
.,. Only use tires with the same de­
s ign , size (rolling circumfer­
ence), and as close to the same
tread pattern as possible on all
four whee ls .
.,. Do not replace tires indiv idually .
At least replace both tires on the
same ax le at the same time .

vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur­
chase
i=:> ,&. .
Because the spare tire* is differ­
ent from the regular tires instal­
led on the vehicle (such as winter
tires or wide tires), only use the
spare tire* temporarily in case of
emergency and drive carefully
while it is in use . It should be re­
placed with a regular tire as soon
as possible.
All four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds . For this rea­
son, in case of emergency, only
use a spare tire* that is the same
circumference as the regular
tires.
A WAR NING ~ -
-Do not use steel rims that are
17 inches or larger. Other-
338
wise, damage to the vehicle
and an accident could result .
-Only use tire/rim combina­
tions and su itable wheel bolts
that have been approved by
Audi . Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use ti res from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle . Replacement
tires should not be c hosen
simply based on the nominal
size, because tires with a dif ­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of
an accident .
-Only use tires that are more
than six years old when abso ­
lutely necessary and drive
carefully when doing so.
- Run-flat tires* may only be
used on vehicles that were

-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.
Tire wear/damage

tor
Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer or authorized Audi Service Facili-

Wheels
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread
pattern, which are bars that are 1/16 in (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running direc­
tion ¢
fig. 2 70. The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The tires have reached the mini­ mum tread depth

have worn down to the treadwear
indicators. Replace the tires with
new ones¢ &.-
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the tires, install the tires from the rear axle ..,.

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash .
Your safety and that of your pas­ sengers also depends on making
sure that load limits are not ex­
ceeded . Veh icle load includes ev­
erybody and everything in and on
the vehicle . These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat ­
ing ("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
Wheels
plus maximum load . The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty ") with an assumed weight of
150 lbs. (68 kg) for each passen ­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle . If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­ ed as part of the vehicle load .
The
Gross A xle Weight Rating
(" GAWR ") is the maximum load
that can be applied at each of the
vehicle's two axles.
T he fact that there is an upper
limit to your vehicle 's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trai ler) is lim ited. The more pas­
sengers in the vehicle or passen ­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage.

are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar.
A WARNING ,-= · -
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death .
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and i ncrease the risk of the loss of
vehicle control.
-The brakes on a veh icle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has been overloaded can fail sud­
denly, including a b lowout and
sudden deflation, causing loss
of contro l and a crash.
-Always make sure that the to­ tal load being transported -i nc luding the weight of a tra il­
er hitch and the tongue
weight of a loaded trailer­
does not make the vehicle
h eavier than the vehicle's
Gross Vehicle Weight Rating.

Determining correct load
limit
Use the example below to calcu­
late the tota l weight of the pas­
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be over load ­
ed.
Steps for Determining Correct Load Limit
1 . Locate the statement " TH E
COMBIN ED WE IGH T OF OCC U­
PANTS AND CARGO SHOU LD
NEVER EXCEED XXX KG OR XXX
LBS" on your vehic le's placard
(tire inflation pressure label)
¢ page 340, fig . 272 .
2. Determine the combined
weight of the drive r and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the stick­
er ¢
page 340, fig. 272 .
4. The resu lting figure equa ls the
available amount of cargo and
luggage load capacity . For ex­

::r ' For example: Tread wear 200, Traction AA, Tem­
perature
A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov­
ernment test course.
For example, a tire graded 150 would wear one
and one ha lf (1 1/2) times as well on the govern­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significant ly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B and
C. Those grades represent the tire's
ability to stop on wet pavement as measured un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete . A tire
marked C may have poor traction performance
¢ &, .
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure¢ &,.
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard
No. 109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
Wheels
A WARNING
--
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics.
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
-
--
Temperature grades apply to tires that are
properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
ill
General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size ind icated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­ ly under -inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­ cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure . Under-inflation
also reduces fue l efficiency and tire tread life,
and may affect the vehicle 's handling and stop-
ping ability. .,.
347

Wheels
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
If the tire pressure monitoring indicator
appears
Applies to: vehicles with Tire Pressure Monitoring System in­
dic ato r
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Using the ABS sensors, the tire pressure monitor ­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires . If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
RI] and a message.
If only one tire is affected , the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
348
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle ~
page 349. The tire pressure moni­
toring system only monitors the tire pressure you have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
~ page 340, fig . 272.
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- the tire pressure in one or more tires is too low
- the tires have structural damage
- the tire was replaced or the tire pressure was
changed and it was not stored

several minutes after storing the pressures until
the indicator light turns off . If the indicator light
does turn off or turns on again after a short peri­
od of time, drive to an authorized Audi dealer or
authorized Audi Service Facility immediately to
have the malfunction corrected.
& WARNING
- If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steering or braking maneu­
vers. Stop as soon as possible and check the
tires and their pressure.

-The driver is responsib le for maintaining the
correct tire pressure. You must c heck the
