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
improp er inflation pre ssure . It i s ther efore important that low
a spect ratio tir es are inflat ed to the sp ec ified pre ssure and th at the
i nflation pr es su re is regularl y checked and mainta ined . Tire pr es­
s ure s should be che cked at le ast once a month and alw ay s before a

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.
Refer to:::;,
page 250 for more de tai led information regarding winter
tires. •
Tire pressure monitoring system
Applies to vehi cles : with tire p ressu re mon itori ng sy stem
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 ,
on e or more of your t ires is s ignific antl y under -infl ated . You should
s top and ch eck your tire s as soon as possible , and inflat e th em to
the p rope r pr ess ure as indi cated on th e vehi cle' s tire pre ssure

& 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.

page 72 , fig. 2@ .
[ i) Tips
• In the case of an intentional loss of air pressure, for example,
when re -adjusting tire pressure, this has to be stored again after ­
wards=>
page 256.
• 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*=>
page 257. •

Storing tire pressures
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
conditions, please see chapter
=> page 238. .,_
