& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard , they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause tire damage , such as
grease , oil , gasoline and brake fluid away from tires .
• Tires age even if they are not being used and can fail suddenly,
espe cially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds .
• Never mount used tires on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •

ture. For example, the numbers 2209 mean that the tire was
produced in the 22th week of 2009. The other numbers are
marketing codes that may or may not be used by the tire manufac
turer. This information is used to contact consumers if a tire defect
requires a recall.
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support. Tire manufacturers also must indi
cate the materials in the tire, which include steel, nylon, polyester,
and others .
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
Tire quality grading for treadwear, traction, and
temperature resistance
Tread wear, traction and temperature grades => page 249.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
Replacing tires or rims on vehicles equipped with tire
pressure monitoring system*
The wheels on your vehicle are equipped with a sensor which
constantly monitors the air pressure inside the tire, and then trans
mits this information to the tire pressure monitoring system *. If you
are going to replace the wheel rims on your vehicle, make sure the
new rims also have these sensors . The sensors must be compatible
with the tire pressure monitoring system * on your vehicle.
If the sensors are to be installed on different rims , the seal, washer ,
and valve cap for each sensor must be replaced.
If you install rims, which do not have the sensors, or have sensors
which are not compatible, then the tire pressure monitoring system* will not work properly.
In this case, the tire pressure moni
toring system * would not be able to monitor the tire pressure or
warn you if it is necessary .
• The battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the valve stem caps securely mounted. We
recommend using factory installed valve stem caps. Ask your autho
rized Audi dealer to replace lost valve stem caps.
The installation of replacement tires with steel cord body plies in
the tire sidewall may cause malfunction of the tire pressure moni
toring system*, and is not recommended (cord material information
in molded on the tire sidewall) .
Always check your tire pressure monitoring system* indicator after
replacing one or more tires on your vehicle. If the tire pressure
monitoring system* indicator flashes, or is on, your system is not
working properly. Your replacement tire might be incompatible with
your tire pressure monitoring sys tem* , or some component o f the
tire pressure monitoring system* may be damaged.
& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control, collision
and serious personal injury.
• Always use tires, rims and wheel bolts that meet the specifica
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer .
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. .,_

Quality grades can be found where applicable on the tire side wall
between tread shoulder and maximum section width
=> page 246,
fig. 152.
For example: Tread wear 200, Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Require
ments 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
government test course .
For example, a tire graded 150 would wear one and one half (1 1/2)
times as well on the government course as a tire graded 100 .
The relative performance of tires depends upon the actual condi
tions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices and differ
ences 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 under controlled conditions on specified government
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 dissi
pate heat when tested under controlled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the material 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 performance which all
passenger car tires must meet under 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.
& WARNING
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established 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. •
Winter tires
Winter tires can improve vehicle handling on snow and
ice. At temperatures below 45 °F (7 °C) we recommend
changing to winter tires.
In some heavy snow areas, local governments may require true
winter or "snow" tires, those with very deeply cut tread. These tires
should only be used in pairs and be installed on all four wheels.
Make sure you purchase snow tires that are the same size and
construction type as the other tires on your vehicle.
I f your vehicle is equipped with all-wheel drive *, this will improv e
traction during winter driving, even with the standard tires.
However, we strongly recommend that you always equip all four
wheels on your vehicle with correctly fitted winter tires or all-season
tires, when winter road conditions are expected. This also improves
the vehicle's braking performance and reduces stopping distances.
Summer tires provide less grip on ice and snow.

& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle's maximum speed . Always know the maximum speed
before driving off . Never drive faster than the speed permitted for
your specific winter tires . This will cause damage to the tires
leading to an accident and serious personal injury to you and your
passengers .
& WARNING
Driving faster than the maximum speed for which the winter tires
on your vehicle were designed can cause tire failure including a
blowout and sudden deflation , loss of control , crashes and serious
& WARNING (continued )
personal injuries . Have worn or damaged tires replaced immed i
ately.
• Winter tires have maximum speed rating that may be lower
than your vehicle' s maximum speed.
• Never drive faster than the speed for which the winter or other
tires installed on your vehicle are rated .
& WARNING
Always adjust your driving to the road and traffi c conditions .
Never let the good acceleration of the winter tires and all -wheel
drive tempt you into taking extra risks. Always remember :
• When braking, an all -wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and reduce your speed on icy and slippery roads,
even winter tires cannot help under black ice conditions .

page 295.
& WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control, a collision and serious personal injury .
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque.
• Only use wheel bolts that belong to the rim be ing installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss .
If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving. If the tightening torque is too high, the wheel
bolts and threads can be damaged and the wheel can become
loose .
0 Note
The specified torq ue for the wheel bolts is 9 0 ft lb (120 Nm) with a
t o lerance of± 7,4 f t lb (± 10 N m). To rque w hee l bo lt s d ia g ona lly .

than the size indicated on the vehicle placard or tire inflation pres
sure label, you should determine the proper tire inflation 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 telltale when one or more of your tires is significantly
under-inflated. Accord ingly, when the low tire pressure te lltale illu
minates, 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 -inflation also reduces fuel efficiency and tire tread
life, and may affect the vehic le's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte
nance, and it is the driver's responsibi lity to maintain correct tire
pressure, even if under -inflation has not reached the level to trigger
il lumination of the TPMS low tire pressure te lltale.
Your vehicle has also been equipped with a TPMS ma lfunction indi
cator to indicate when the system is not operating properly . The
TPMS malfunction indicator is combined with the low tire pressure
telltale. When the system detects a malfunction, the tellta le wi ll
flash for approximately one minute and then remain continuously illuminated. This sequence wil l continue upon subsequent vehicle
start -ups as long as the malfunction exists .
When the ma lfunction indicator is illuminated, the system may not
be able to detec t or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the
installat ion of replacement or a lternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly . A lways
check the TPMS malfunction tellta le after replacing one or more
tires or whee ls on your vehicle to ensure that the rep lacement or
a lternate tires and wheels al low the TPMS to continue to function
proper ly .•

Introduction
The tire pressure monitoring system* monitors air pres
sure in all four road wheels while the vehicle is moving.
As soon as the tire pressure monitoring system* senses a signifi
cant loss of air pressure in one or several tires, text messages and
yel low symbols appear in the instrument cluster disp lay to alert the
driver. The ) warning light in the instrument cluster comes on
when the tire is significantly underinflated
:::> page 17 .
The warning light Cl' also i lluminates in the case of a system
malfunction.
Be aware that tire pressure is a lso dependent on the temperature of
the tire. For every 18
°F (10 °C) increase in tire temperature, tire pres
sure increases by about 1.5 psi (0 .1 bar). The tire warms up while the
vehic le is moving and tire pressure rises. So you should adjust tire
pressure only when they are
cold, when the temperatu re of the t ires
is roughly the same as the ambient air temperature .
I n order to keep the tire pressure monitoring system * properly ca li
brated, tire pressure on all four tires shou ld be checked at regu lar
intervals, adjusted if necessary and saved in the proper setting
(recommended pressure)
:::> page 256 .
The tire pressure is shown on the label located on the driver's side

& WARNING (continued)
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i] Tips
• Each tire should be checked monthly when the temperature of
the tires is about the same as ambient air temperature and set to the
recommended inflation pressure as specified on the tire pressure
label =>
page 238.
• The factory supplied spare wheel is equipped with a sensor for
the tire pressure monitoring system *. As long as the spare wheel is
not mounted, the tire pressure of this tire will not be monitored.
• The tire pressure monitoring system * helps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• When tires are replaced, the sensors and valves should not be
exchanged . The valve core, nut, valve sealing and seal washer
(replacement kit) needs to be replaced. If necessary, the valve and
the wheel electronics have to be replaced.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system*.
Otherwise the system will register a malfunction and a fault
message will be displayed. For more information, contact your Audi
dealer. •
Adjust the tire pressure and store the pressure in the tire pres
sure monitoring system* to the load you are carrying.

In order for the tire pressure monitoring system* to operate
appropriately, you have to re-save the specified pressures
whenever you adjust tire pressures, for example when the
load condition of your vehicle changes . Proceed as follows:
Correcting tire pressure
Check the pressure in the tires.
Adjust air pressure as needed to comply with the infor mation on the label located on the driver's side B -pillar
(vis ible when the door is open).
Saving tire pressures
Turn on the ignition.
Press the button=> fig. 154 for app roximately 5 seconds.
You will hear a beep and the symbol in the instrument
cluster flashes three times.
All pressure warning indicators in the display will be canceled.
Following each intentional change in specified pressures, tire pres
sures must be resaved.
After the pressures are saved, the tire pressure monitoring system* measures the current tire pressures and saves them as the new
specified pressures.
[ i J Tips
• The tire pressure is shown on the tire pressure label. The tire
pressure label is located on the driver's side B-pillar (visible when

Run-flat tires
Ap plies to ve hic les : w it h R un -f la t tires
Introduction
Run-flat tires help keep you moving if a tire goes flat.
Re inforced sidewalls give the tires run -flat capability if t ire pressure
is lost .
We recommend that run -flat tires only be mounted on vehicles that
were origina lly equipped with these special tires at the factory and
have a Tire Pressure Monitoring System.
Run-flat tire s can be identified by the letter s "RSC" on the tire side
wa ll.
If you do change the tires on you r vehicle from normal to run -flat
tires , you must buy the special rims required for run -flat tires, and
the Tire Pressure Mon itoring System must be reprogrammed by an
authorized Audi dea ler or other qual ified workshop.
What do run -fl at tires do ?
These specia l tires have run-flat capabilities that help keep you
moving if a tire loses pressure and goes flat. Under favorab le condi -tions tires can be driven
a
t lea st 30 mile s (50 km ), but you must not
drive
fa ster than 50 mph (80 km/h )=> page 259, "Driving with run
flat tires".
