& W ARNING (continu ed )
• All four wheels must be fitted with radial tire s of the same type ,
s ize (rolling cir cumference ) and the same tread pattern . Driv ing
with different t ires redu ces vehicle h andling and can lead to a loss
of contro l.
• If the spare tire is not the same a s the tires that are mounted
on the vehicle -for e xample with winter tires -only use the spare
tire for a short period of time and dr ive with extra c are . Refit the
norm al road wheel as soon as safely possible .
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tires cause heat build-up , sudden tire failure ,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to t ires that are properly inflated and
not over or underinflated .
• For te chnical reasons it is not always possible to use wheels
from other vehicles -in some cases not even wheels from the
same vehicle model.
• If you install wheel trim discs on the vehicle wheels , make sure
that the air flow to the brakes is not blo cked . Redu ced airflow to
the brakes can them to overheat , in creasing stopp ing distances
and causing a collision .
• Run flat tires may only be u sed on vehicle s that were equipped
with them at the fa ctory . The vehicle must have a chassis de signed
for run flat tires and a factory -installed tire pressure monitoring
system* that indicates a loss of tire pressure. In correct use of run
flat tires can lead to vehicle damage or accidents . Check w ith an
autho riz ed Audi dealer or tire specialist to see if your vehicle can
be equipped with run flat tires . If run flat tires are used, they must
be installed on all four wheel s. Mixing tire types is not permitted .
0 Note
• For techn ica l reaso ns, it is not genera lly poss ib le to use t he
whee l rims from other vehicles. This can hold true fo r wheels of the
same vehicle type .
• I f the s pare t ire is d ifferent from the tires that you have mounted
on your vehicle ( fo r example win te r ti res or wide p rofile tires), then
use the spa re tire for a short period of time on ly and drive with extra
care. Replace t he flat tir e w ith the tire matching the others o n your
vehic le as soon as possib le.
• If you s hould put different whee ls a nd tires on your ve hic le (e.g.
winter wheels and tires), you must be certain that the whee ls and
t ires are co mpa tibl e w ith the tire pressure mon itor in g syste m*.
Otherwise the system w ill reg ister a malfunction and a fault
m essage w ill be d isplayed . For more info rma tion, co ntact your Aud i
dea ler.

• When installing new tires, be careful not to damage the va lves or
tire p ressu re m on itoring system senso rs* .
• N ever drive without the valve stem cap. The valves could get
da mage d.
• I f the sensors must be replaced, then the valve must also be
r eplaced at the same time.

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 .

Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These t ires
have been thorough ly tested and been selected specifically for your
model for their superb performance , road feel and hand ling under
a variety of driving conditions . Ask your authorized Audi dealer for
more deta ils.
The low aspect rat io of these t ires is indicated by a numera l of
5 5 or
les s
in the tire's si ze designation. The numeral represents the ratio
of the tire's sidewa ll height in relation to its tread wid th expressed
in perc entage. Conv entiona l tires have a h eight/width ratio of 60 or
more .
The p erform an ce of lo w-aspe ct-r a tio tire s is pa rti cula rly sen siti ve to

247, "Checking tire pressure".
What you can d o to av oid tire and rim d amage
Low aspect ratio tires can be damaged more easi ly by impact with
potholes, curbs, gul lies or r idges on the road, particularly i f the t ire
is underinflated.
In order to min imize the occurrence of impact damage to the tires
of your vehicle , we recommend that you observe the following
precautions:
• Always maintain recommended inflat ion pressures . Check your
tire pressure every 2 ,000 miles (3,000 km) and add air if necessary.
• Drive carefully on roads with potholes , deep gullies or ridges.
The impact from driving through or over such obstacles can
damage your t ires. Impact with a curb may also cause damage to
your tires . •
After any impact , immediately inspect your tires or have them
inspected by the neares t authorized Audi dea ler . Replace a
damaged tire as soon as possib le.
• Inspec t you r tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see. Damage can lead to loss of
air and underin flation, which cou ld eventua lly cause tire fai lure. If
you be lieve that a tire may have been damaged , replace the tire as
soon as possible .
• These tires may wear more quickly than others.
• Please also remember that, while these tires de liver responsive
handling, they may ride less comfortably and make more noise than
other choices.
R edu ced p erform an ce in w int er/c old sea son
c ondition s
All tires are designed for c ertain purposes . The low aspect ratio,
ultra h igh performance tires origina lly instal led o n your vehic le are
intended for maximum dry and wet road performance and hand ling.
They are no t sui table for cold, snowy or icy weather conditions . If
you drive under those circumstances , you should equip your vehic le
with al l- season or winte r ti res, which offer better tract ion under
those conditions . We suggest you use the recommended snow or
all -season tires specified for your vehicle, or their equiva lent.

General notes ....J
Each t ire, including the spare (if p rovided), should be checked
month ly when co ld and inflated to the inflation pressure recom­
mended by the vehicle manufacturer on the vehicle placa rd or tire
inf la tion pressure label. ( If your vehicle has tires of a different s ize _,.
Vehicle care I t •

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
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
B -pillar (visible when the door is open) .
& WARNING
• When the tire pr essure monito ring system * wa rning light i s lit ,

& 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.

• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air tempera ture.
• The yellow symbol disappears, when the tire pressure is
correc ted and the new pressure is stored in the system=>
page 256.
• After changing a wheel or replacing a wheel with the spare tire
you have to adjust the tire pressures on all wheels. In addition , you
must then initialize the new tire pressures in the tire pressure moni ­
toring system*=>

Correct storage of specified pressure is the basic require ­
ment for reliable tire pressure monitoring.
Fig. 154 SET-button :
Tire pressure moni­
toring system
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
the door is open). The tire pressure label lists the recommended cold tire inflation pressures for the vehicle at its maximum capacity
weight and the tires that were on your vehicle at the time it was
manufactured . For recommended tire pressures for normal load

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".
The Tire Pressure Monitoring System constant ly checks the air pres ­
sure in the tires. If the run-flat system is active (shown in the center
display), you must inspect the affected t ire or t ires and then decide
whether to cont inue dr iving. Be sure to fol low these tips
=> page 259, "Driving with run -flat tir es" .
