&_ WARNING . -
-Only use tire/rim combina-tions and suitable 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 tires from
the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen 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.
-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
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. .,..

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. Vehicle 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 ..

plus maximum load . The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seat ing 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 Axle Weight Rating
(" GAWR") is the maximum load
that can be applied at each of the
vehicle 's two axles.
The 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
trailer) is limited . 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.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating

are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar
~ page 327,
fig . 255 .
& 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 increase the risk of the loss of
vehicle control.
-The brakes on a vehicle 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 blowout and
sudden deflation, causing loss
of control and a crash .
-Always make sure that the to­ tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer - does not make the vehicle
heavier than the vehicle 's
Gross Vehicle Weight Rating.

Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport
so that you can ma ke sure that
your vehicle will not be overload­ ed .
Steps for Determining Correct
Load Limit
1 . Locate the statement "THE
COMBINED WEIGHT OF OCCU­ PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle 's pla card
(tire inflation pre ssure l abel)
¢ page 327, fig. 256.
2 . Determine the combined
weight of the drive r and pas­
s engers that will be riding in
your vehicle.
3 . Subtra ct the combined weight
of the driver and passengers
from
" XXX" kilograms or "XXX"
pounds shown on the stick­
er ¢
page 32 7, fig . 256.
4. The re sulting figure equals the
available amount of cargo and
luggage load capacity. For ex-
; ample, if the
"XXX" amount

Low aspect ratio tires
Your Aud i is facto ry-equipped with low aspect ra ­
tio ti res. These t ires have been tho rough ly tested
and been se lected specifically for yo ur model for
their superb per formance, road feel and handling
under a variety of driving conditions. Ask your au­
thorized Audi dealer for more details .
The low aspect ratio of these t ires is indica ted by
a numera l of
55 or les s in the tire's size designa ­
tion. The numeral represents the ratio of the
tire's sidewall height in r elation to its tread width
expressed in percentage. Conventional tires have
a height/w idth rat io of 60 or more.
The performan ce of low-aspect- ratio tire s is par­
ticularl y sensiti ve to improper inf lat ion pres­
sure . It is therefore impo rtant that low aspect
ratio tir e s are infl ated to the specified pressu re
and tha t the inflation pr essure is regularly
checked and maint ained . Tire pre ssure s should
be check ed at lea st once a month and alwa ys
b efore a long trip<=:>
page 32 7.
What you can do to a void tire and rim
damage
L ow aspect rat io tires can be damaged more easi­
l y by impact with potho les, cu rbs, gull ies or
r idges on the road, pa rtic ularly if the tire is un­
derinflated.
Wh eel s
In order to min imize the occurrence o f impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau ­
t ions:
- Always maintain recommended inflation pres ­
sures . Check your tire pressure every 2,000
m iles (3,000 km) and add air if necessary .
- Drive carefully on roads with potholes, deep
gu llies or ridges . The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immed iate ly inspect your
tires or have them inspected by the nearest au­
thorized Audi dealer . Replace a damaged tire as
soon as possible .
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not always
easy to see . Damage can lead to loss of a ir and
underinflation, wh ich could eventually cause
tire fa ilu re . If yo u bel ieve that a tire may have
been damaged, replace the tire as soon as pos­
sible.
= These tires may wear mo re quickly tha n others.
- Please also remember that , while these tires
de live r responsive ha nd ling, they may ride less
comfort ably and make more noise t han other
choices .
Reduced performance in w inter /cold season
conditions
All tires are des igned for certai n pu rposes. The
low aspect ratio, ultra high performance tires
origina lly installed on your vehicle are intended
for maximum dry and wet road performance and handling. They are not suitable for co ld, snowy or
icy weather conditions. If you drive under those
c ircumstances, you should equip your vehicle
with all -season or winter tires, which offer better
tract ion under those conditions . We suggest you
use the recommended s now or a ll-season tires
spe cified for your vehicle, o r their equiva lent.

to <=:> page 332 for more detailed informa ­
t ion regard ing winter tires.
Uniform tire quality grad ing
- Tread wear
333

Wheels
-Traction AA A BC
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width
~ page 317, fig. 253.
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 half
(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 significantly 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, Band
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 failur e~ ,& .
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un-
334
der the Federal Motor Vehicle Safety Standa rd
No. 109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
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 indicator
(l) 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 indicated on
the veh icle 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

significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-infla­
tion also reduces fue l eff ic iency and tire tread
life, and may affect the vehicle's hand ling and
stopping ab ility.
Please note that the TPMS is not a substitute for
proper tire ma intenance, and it is the driver's re­
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the leve l
to tr igger illum inat io n of the TPMS low tire p res­
sure telltale .
Your veh icle has also been equ ipped w ith a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operat ing properly. The TPMS mal­
function ind icator is combined w ith the low tire
p ressure tellta le. Whe n the system detects a
malfunct ion, the te lltale will flash fo r approxi­
mate ly one m inute and then remain cont inuo usly
illum inated. This sequence will continue upon
subseq uent ve hicle start -ups as long as the ma l­
function exists.
When t he mal funct io n ind icator is ill umin ated,
the system may not be ab le to detec t or signal
l ow tire pressure as intended. TPMS ma lfunctions
may occur for a variety of reasons, incl uding the
installation of replacement or alternate t ires or
wheels on the vehicle that prevent the TPMS from functioning properly. Always check the
TPMS malfunction telltale after rep lacing one or
more t ires or whee ls on your ve hicle to ensu re
that the replacement or alte rnate ti res and
wheels a llow the TPMS to con tinue to func tion
p roperly.
If the Tire Pressure Monitoring System
indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system mo/function.
Using the ABS sensors, the tire pressure mo nitor ­
ing system compa res the tire tread circ umfe r­
ence an d vib ration cha racteristics of the individ u­
a l tires. If the pressure changes in one or more
tires, this is ind icated in the instrument cluster
