A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max
imum speed. Always know the maximum
speed before driving off . Never drive faster
than the speed permitted for your specific
w inte r tires . This will cause damage to the
tires leading to an ac cident and serious
pe rsonal inj ury to you and yo ur passen
gers .
A WARNING
Driv ing faster than the maximum speed
for which the winter tires on your vehicle
were designed can ca use tire fai lure in
cl uding a blowout and sudden deflat ion,
loss of control, crashes and serious per
sonal injuries . Have worn or damaged tires
rep laced immed iate ly.
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for
w hich the winter or other tires installed
on your veh icle are rated .
A WARNING
Always adjust your d rivi ng to the road and
traffic conditions. Neve r let the good ac
c eleration of the w inte r ti res and all-whee l
drive temp t you in to taking extra r is k s . A l
ways remember:
- When bra king, an a ll-wheel d rive vehicle
hand les in the s ame way as a front drive
vehicle.
- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under blac k ice conditions.

@) For the sake of the environment
Use summer tires when weather condi
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
Snow cha ins may be fitted only to the rear
wheels, and o nly to certain tire sizes . Ask your
autho rized Aud i deale r on which tire sizes
snow cha ins can be used .
The snow chains must have low-prof ile links
and must not be th icker than 0.53 inch
(13.5 mm) , includ ing the lock .
Remove wheel center covers and trim discs
before putt ing snow cha ins on your vehicle
c::> Q) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are ava il
able from autho rized Aud i dealers.
A WARNING
Using the wrong snow chai ns for your vehi
cle o r insta lling them incorrect ly can in
crease the risk of loss of cont ro l leading to
serious personal injury.
- Snow chains are available in different
sizes. A lways make sure to follow the in
structions p rov ided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specif ic snow chains.
- Always observe local regulations .
(D Note
-Remove snow chains before dr iv ing o n
roads not covered with snow to avoid
damaging tires and wea ring the snow
chains down unnecessarily.
- Snow chains, which come into direct con
tact with the whee l rim , can scratch or
damage it . Therefore, make sure that the
snow chains are suitably covered. Check
the pos ition of the snow chains after

driving a few yards and correct if neces
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer
tain roads, this normally also applies to
veh icles with all-wheel dr ive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory insta lled rims . If different rims are fit
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
¢ page 295.
.&_ WARNING
Improperly tig htened or maintained wheel
bolts can become loose ca using loss of
cont ro l, a co llision and serious p ersona l in
Jury.
- Always keep the wheel bolts and the
threads in t he wheel hubs clea n so the
wheel bolts can tu rn easily and be prop
erly tigh tened.
- N ever grease or oil the wheel bo lts and
the threads in the wheel h ubs. They can
become loose w hile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- Only use wheel bolts that be long to the
rim being installed.
- N ever use different whee ls bolts on your
vehicle.
- Always mai nta in the co rrec t tighte ning
tor que fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor
que of the wheel bo lts is too low, they
can loosen and come out when the veh i- cle is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be
come loose.
(D Note
The specified torque for the whee l bolts is
105 ft lb (140 Nm) with a to lerance of
± 7,4 ft lb(± 10 Nm). Torque wheel bolts
diagonally . After changing a wheel, the
torque must be checked as soon as poss i
ble with a to rque wrench -preferab ly by an
a uthorized Aud i dea le r or qualified wor k
shop.
Low aspect ratio tires
Your A udi is factory -eq uipped w it h low aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi
t ions . Ask your authorized Audi dealer for
more details .
The low aspect ratio of these tires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the tire's sidewall height in relation to its
t read width exp ressed in percentage. Conven
tiona l tires have a he ight/w idth rat io of 60 or
more.
Th e performanc e of low-a spect-ratio tire s is
pa rticularly sensi tive to improp er inflation
pre ssure. It i s ther efor e important that low
a spe ct ratio tir es are inflated to the spe cified
pre ssure and that the inflation pre ssure i s
regula rly checked and mainta ined. Tire pre s
sure s should be checked at lea st once a
month and al way s befo re a long trip
¢ page 2 53, Checking tire pressure.
What you can do to a void tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w ith potholes, curbs, gul lies
or ridges on the road, particularly if the tire is
underinflated . ..,.
Page 267 of 316

In o rder to minimize the occurrence o f impact
damage to the tires of your vehicle, we recom mend that you observe the following precau
tions :
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add a ir if neces
sary.
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires .
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer . Replace a damaged
t ire as soon as poss ible .
- In spect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al
ways easy to see. Damage can lead to loss of
air and unde rinflation, wh ic h could eventu
ally cause ti re fail ure.
If yo u be lieve that a
ti re may have been damaged , replace the
tire as soon as possible.
- These tires may wear more quick ly than oth
ers.
- Please a lso remembe r that, whi le these t ires
deliver respons ive handling, they may ride
less comfortably and make more noise than
other c hoices.
Reduced p erformance in winter /cold
s ea son condit ion s
All ti res are designed for certain purposes .
The low aspect ratio, ultra hig h performance
tires originally installed on your veh icle are in
tended for max imum dry and wet road per
formance and handling . They are not suitable
for cold, snowy or icy weather cond it ions . If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, whi ch offe r better traction under
those cond it ions . We suggest you use the rec
ommended snow or all -season tires specified
for your ve hicle, or their equiva lent .

Tire pressure
monitoring system
ill General notes
App lies to vehicles : wi th tire p ress ure mo nito rin g system
Each tire, incl uding the spare (if provided),
shou ld be checked monthly when co ld and in
flated to the inflation pressure recommended
by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a d ifferent size than the
s iz e indicated on the vehicle placard or tire in
flat io n pressu re labe l, you shou ld dete rmine
the p roper t ire inflation p ress ure fo r those
t i r es).
As an added safety feature, your veh icle has
been equipped with a tire pressure monitoring
system ( TPMS) that illum inates a low ti re
pressure te lltale whe n one or more o f your
ti res is significant ly under -inflated . According
ly, when the low tire pressure te lltale i llumi
nates, you shou ld stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly un
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under-inflation al
so reduces fuel effic iency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing abil ity.
Please note that the TPMS is not a subst itute
fo r proper tire ma intenanc e, and it is the d riv
er's respo nsibility to maintain co rrect tire
pressure, even if under-inflation has not
reached the leve l to tr igger illum inat ion of the
T PMS low ti re p ressu re tellta le .
You r vehicle has also been equipped with a
T PMS ma lf u nction indicator to ind icate w hen
the sys tem is not operating prope rly . T he
T PMS ma lfunction indicator is combined w ith
the low tire pressure te lltale. When the sys
tem detects a malfunction, the telltale wi ll
flash for approximate ly one min ute and then
rema in con tinuously i llum inated . T hi s se
quence will continue upon subsequent vehicle
start-ups as long as the malfunct ion exists . ..,.

266 Tire s and wheels
When the malfunction indicator is illuminat
ed, the system may not be able to detect or
signal low t ire pressure as intended. TPMS
malfunctions may occur for a variety of rea
sons, including the installation of replace
ment or alternate tires or wheels on the vehi
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunct ion
tellta le after replacing one or more t ires or
wheels on your veh icle to ensure that the re
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.

A WARNING
=
- If the tire pressure indicator appears in
the instrument cluster display, one or
more of your tires is sign ificant ly under
inflated. Reduce your speed immediately
and avoid any hard steer ing or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In
flate the tire pressure to the proper pres
sure as ind icated on the vehicle's tire
p ressu re lab el¢
page 251. Driving on a
significantly under-inflated tire causes
Page 269 of 316

the tire to overheat and can lead to tire
failure. 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 regularly.
- Under certain conditions (such as a spor
ty driving style, winter conditions or un paved roads), the pressure monitor indi
cator may be delayed.
-Ask your authorized Audi dealer if run flat tires may be used on your vehicle .
Your vehicle registration becomes invalid if you use these tires when not permit
ted. Damage to your vehicle or accidents
could also result.
@ Tips
- The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
your Audi was developed using tires with the "AO" or "RO" identification on the
tire sidewall¢
page 258. We recom
mend using these tires.
Reset tire pressure monitoring system
Applies to vehicles: with tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro
tated or changed, the TPMS must be reset via
