Tire pl y compo sit ion and materi als used
The numbe r of plies ind icates the n umber of
l ayers of rubber -coated fabric in the tire. In
general, the greater the number of p lies, the
more weight a tire can support . Tire manufac­
turers also must indicate the materials in the
tire, wh ic h include steel, nylon, polyester, and
others.
M ax imum Load R ating
This number indicates the maximum load in
kilograms and pounds that can be carried by
the tire .

This numbe r is the greates t amo unt of air
p ress ure that sho uld ever be put in the ti re
under normal driving conditions .
A WARNING
-Us ing incorrect or unmatched tires and/
or wheels or improper tire and wheel
combinations can lead to loss of contro l,
co llision and serious persona l injury .
- Always use tires, rims and wheel bo lts
that meet the specifications of orig inal
factory-installed t ires or other combina­
t ions that have been spec ifically ap­
proved by the vehicle manufacturer.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds. Tir es that are more than 6 years
o ld can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used ti res on yo ur vehicle if
yo u are not su re of their "previous histo ­
ry ." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure and loss of vehicle control.
- All four wheels must be fitted with radia l
t ires of the same type, size (roll ing c ir- cumference) and the same tread pattern
.
Driving with different tires reduces vehi­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires - only use
the spare t ire fo r a short pe riod of time
and d rive with extra care . Refit the nor­
mal road wheel as soon as safely poss i­
b le.
- Never d rive faster than the max imum
speed for which the tires on you r vehicle
are rated because tires that are dr iven
faster than their rated speed can fai l
suddenly .
- Overloading tires cause heat build-up,
sudden tire fa ilure, including a blowout
and sudden deflation and loss of cont ro l.
- Temperature grades apply to tires that are properly inflated and not over or un­
de rinf lated .
- For technica l reasons it is not always
possible to use whee ls from other
veh icles -in some cases not even wheels
from the same veh icle model.
- If you install wheel trim discs on the ve­
hicle wheels, make sure that the a ir flow
to the brakes is not blocked. Reduced air­
f low to the brakes can them to overheat,
increas ing stopp ing distances and caus­
ing a co llision.
- Run flat tires may only be used on veh icles that were equipped with them
at the factory. The veh icle must have a
chassis designed for run flat tires and a
f a ctory -inst alled tire pressure monitor­
ing sys tem * that indicates a loss of tire
pressu re . I ncorrect use of run flat tires
can lead to vehicle damage or accidents.
Check with an authorized Audi dealer or
tire specialist to see if your vehicle can be
equ ipped w ith run flat t ires. If run flat
tires are used, they must be installed on
all fo ur wheels . Mix ing tire types is not
pe rm itted.

pressures for your vehicle on the label on driv­

- the tire pressure in one or more t ires is too

- the tire has st ructu ral damage,
- the tire pressure was changed, wheels rotat-

Iflll appears after switching the ignit ion on
or while driving and the
rD] i ndicator light in
the instrument cluster blinks for approxi­ mately one mi nute and the n stays on, the re is
a system ma lfunction.
Attempt to store the correct tire pressure
¢ page 250. If the ind icator light does not
turn
off or if it tu rns o n short ly thereafter, im­
mediately drive your veh icle to an autho riz ed
Aud i dea ler or autho rized repair facility to
have the ma lfunction corrected.
A WARNING
- If the tire pressure indicator appears in
the instrument cl uster d isplay, one or
more of your tires is s ignificantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braki ng
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures. In­
flate the tire pres sure to the proper p res­
s u re as in dic ated on the vehicle 's t ire
pressure label¢
page 234 . Driving on a
significantly under-inf lated tire ca uses the tire to overheat and can
lead to tire
fa ilure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regu larly .
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi ­
cato r may be delayed .
-Ask your authorized Aud i dea ler if run­
flat t ires may be used on you r vehicle.
Your vehicle registration becomes invalid
if you use these t ires when not perm it­
ted. Damage to your vehicle or accidents
could a lso result.
(D Tips
- The tire pressure mon itoring system
stops work ing whe n there is an ESC/ABS
m alfu nction.
- Us ing snow chains may result in a system
ma lf u nction.
- The tire pressure mon itoring system on
your Audi was deve loped using tires with
t he "AO" or "R O" ident ifi cat ion on the
tire sidewa ll¢
page 242 . We recom ­
mend using these tires.
Reset tire pressure monitoring system
Appl ies to vehicles: wit h tire p ressu re mo nito rin g system
If the tire pressure is adjusted, wheels are ro ­
tated or changed, the TPM5 must be reset via
radio or MMI*.
" Before resetting t he TPM S, the c urrent pres­
sures of a ll four tires must correspond to
the specified values . Ad just the tire p ressu re
and reset the pressure in the tire pressure
mon itoring system according to the load
you are carrying

A WARNING
The compressor and the tire filler hose can
become extremely hot while they are run­
ning -danger of burns!
(D Note
Switch the compressor off after running
for 12 minutes at the most -danger of
overheating! Allow the compressor to cool
down for a few minutes before you use it
again.

A WARNING
You or your passengers could be injured
while c hanging a wheel if you do not fo l­
low these safety precaut ions:
- If you have a flat tire, move a safe d is­
tance off the road . T urn off the engine,
tur n the eme rg ency flashers on and use
other wa rn in g devices to a le rt othe r mo­
torists.
- Ma ke sur e that passengers wait in a safe
p lace away from the vehicle and well
away from the ro ad and traffic.
- T o help prevent the vehicle from moving
suddenly and possib ly sli pping off the
j a ck, alw ay s full y se t the par king br ake
an d block the wheel d iagonally opposi te
the whee l be ing changed w ith the fol d­
ing chocks or other objects. When one
front wheel is lifted off the ground, plac­ ing the Automatic Transmission in "P"
(Park) will
not prevent the vehicle from
moving .
- Before you change a wheel, be sure the
grou nd is level and firm. I f necessary,
use a sturdy board unde r the jack .
- Always sto re the vehicle tool kit, the
jack* and the replaced tire in the luggage compa rtment
¢page 134.
(D Note
If you are changing the whee l on a steep
i ncline, use a rock or s imilar object to
block the opposite whee l to prevent the
vehicle from moving.
(D Tips
Obey all laws.
