_& WARNING -
-Only use tire/rim combinations 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 6 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
Wheels
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 repair facility
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 Rating
("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 ""
217
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 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
218
are listed on the safety compli
ance sticker label located on the
driver's side B-pillar
¢ page 215,
fig . 170.
.&_ 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 in
crease 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 vehi cle's pla card
(tire inflation pressure label)
¢ page 215 , fig. 170.
2 . Determine the combined
weight of the driver 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"
pound s shown on the sticker
¢ page 215 , fig. 170 .
4. The resulting figure equals the
available amount of cargo and luggage load capacity. For ex
ample, if the
" XXX" amount
equals 1400 lbs. and there will
Wheels
be five 1 SO lb s. passenger s in
your vehicle, the amount of available cargo and luggage load capa city is 650 lb s.
(1400-750 (5 X 150) = 650
lb s.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle .
That weight may not safely e x
c eed the available cargo and
luggage load capa city cal culat
ed in Step 4 .
6. If your vehicle will be towing a trailer, load from your trailer
will be transferred to your vehi
cle. Con sult thi s manual to d e
termine how this redu ce s the
available cargo and luggage load capacity of your vehicle .
.,.Check the tire sidewall
(¢ page 205 , fig. 168) to deter
mine the designated load rating
for a specific tire.

me nd that yo u observe the follow ing p recau
t ions:
- Alw ays m aintain r eco m me nded infl ation pre s
sures. C heck your tire pressure every 2,000
m iles (3,00 0 km) an d ad d air if necessary .
- Dr ive c arefully on road s wi th pot holes, deep

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 air and
unde rinflation, w hich could even tually cause
t ire failure .
If you beli eve that a t ire may have

For example: Tr ead wear 200 , Tract ion AA, Tem
peratu re
A .
All passenger ca r tires must confo rm to Federal
Safety Req uiremen ts in add it ion to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
unde r controlled conditions on a spec ified gov
ernment test course.
For examp le, a t ire graded 150 would wear one
and one half ( 1 1/2) t imes as well on the govern
ment course as a tire graded 100 .
The relat ive performance of t ires depends upon
the actua l conditions of their use, however, and
may depart significantly from the norm due to
variations i n driving hab its, service practices and
d iffe rences in road character istics and clima te.
Traction
The traction grades, from highest to lowest, are
AA, A , Band
C. Those grades represent the tire's
ab ility to stop on wet pavement as measu red u n
de r controlled cond it ions on spec ified govern
ment test su rfaces of asphalt and concrete. A tire
marked C may have poor traction performance
c::> &_ .
Temperature
The temperature grades are A (the highest), B,
a nd C, rep resent ing t he tire's res istance to the
genera tion of heat and its a bility to dis sipate
heat w hen tested unde r controlled cond itions on
a specified indoo r laboratory test whee l.
Sustained high temperature can cause the mate rial of the tire to degenerate and red uce tire life,
a nd excessive tempera ture can lead to sudden
tire failure
c::> &. .
The grade C co rresponds to a level of perform
ance wh ich a ll passenge r ca r tires m ust meet un
de r th e Federal Motor Vehicle Safety S tandard
No. 109. G rades Band A represent higher levels
222
of pe rformance on the laboratory test whee l than
the minimum required by law .
A WARNING -
The traction grade assigned to th is tire is
based on straight-ahead braking tract ion
tests, and does not include acce lerat ion, cor
nering, hyd roplaning or peak traction charac
teristics.
A WARNING
The temperature g rade for th is tire is estab
lished for a tire that is properly inf lated and

Tire pressure monitoring system
(l) General notes
App lies to vehicl es: wi th tire p ress ure mo nito rin g system
-
Each tire, incl uding the spare (if provided),
sho uld be checked monthly when co ld and inflat
ed to the inflat ion pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a different s ize than the size indicated on
the ve hicle placard or t ire inflation pressu re la
bel, you should dete rm ine the p roper t ire infla
tion pressu re for those t ires).
As a n added safety feature, your ve hicle has been
equipped with a tire pressure mon itor ing system
( TP MS) that illum inates a low t ire pressure te ll-
ta le w hen o ne or mo re of yo ur ti res is sign ificant -
l y unde r-i nflated. According ly, w hen t he low t ire
pressure te lltale illuminates, you shou ld stop and
check yo ur tires as soon as possible, and inflate
them to the proper pressure . Dr iving on a signifi
cant ly under-inf lated tire causes the t ire to over
heat and can lead to tire failure. Under-inflation .,,.
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop
ping ability .
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
malfunct ion, the telltale will flash for approxi
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent veh icle 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.
