chains because the vehicle will be ex
tremely low. If you do drive with snow
chains on while the vehicle is at this lev
el, the snow chains might severe ly dam
age the wheelhouse and other parts of
the veh icle.
(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 installed r ims. If different rims
are fit
ted, the correct wheel bolts with the right length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
secure ly 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 mode l
¢page 287.
_& WARNING
Imprope rly tig htened o r maintained whee l
bolts can be come loose ca using loss of
contro l, a co llision and serious persona l in
jury.
- Always keep the wheel bol ts an d the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be prop
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel h ubs. They can
become loose w hile driving if greased or
oiled, even if tightened to the specif ied
torque.
- Only use wheel bolts that belong to the rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintain the correct tighten ing
torq ue for the wheel bo lts to reduce the risk of a whee
l loss. If the tightening tor
que of the wheel bolts is too low, they
can loosen and come out when the vehi
cle is mov ing. If the tighte ning torque is
too high, the wheel bolts a nd threads
can be damaged and the whee l can be
come loose.
([) Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torque whee l bolts diago
nally. Afte r changing a whee l, the torque
must be checked as soon as possible wi th a
torque wrench -pre ferably by an au thor
ized Audi dealer or qualified workshop .
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and hand ling u nder a var iety of d riv ing condi
t ions . As k your author ized 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 rep resents the ratio
of the t ire's s idewa ll height in relation to its
t read width ex pressed in percentage. Conven
t iona l tires have a he igh t/w idth rat io of 60 or
more.
The performanc e of low -a sp ec t-ratio tires i s
pa rticularly sensitive to improper inflation
pre ssure . It is therefore important that low
a spect ratio tires are inflated to the specified
pre ssure and that the inflation pressure i s
regularly checked and maintained. Tire pre s
sures should be checked at least once a month and always befo re a long trip
¢ page 249, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w ith potholes, curbs, gull ies .,..

or ridges on the road, particularly if the tire is underinflated .
I n o rder to m inim ize the occu rrence of impact
damage to the t ires of your veh icle, we recom
mend that you observe the following precau
tions :
- Always maintain recommended inflat ion
pressures. Chec k your tire pressure every
2,000 miles (3 ,000
km) and add air 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 a lso
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 possible .
- Inspect 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 underinflation, wh ich could eventu
ally cause tire failure . If you be lieve that a
t ir e may have been damaged , replace the
t ire as soon as possible.
- T hese tires may wea r mo re qui ck ly than ot h
ers.
- Please a lso remember that, whi le these tires
deliver respons ive handling, they may ride
l ess comfortably and make mo re noise than
othe r choices.
Reduced performance in winter /cold
season condition s
All tires are des igned for certa in pu rposes.
The low aspect ratio, ultra high performance
tires originally installed on your veh icle are in
tended for maximum dry and wet road per
formance and handling . They are not suitable
for cold , snowy or icy weather condit ions .
If
you dr ive under those circums tances, you
should equip your veh icle with all -season or
winter tires, which offer better traction under
those cond itions . We suggest you use the rec
ommended snow or all-season tires specified
for your ve hicle, or their equ ivalent.

mation regard ing winter tires.
Tire pressure
monitoring system
ill General notes
Applies to veh icles: w ith t ire pressure monitoring system
Each tire, incl uding the spare (i f provided),
shou ld be checked monthly when co ld and in
flated to the inf lation pressure recommended
by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle ha s tires of a different size than the
s ize indicated on the vehicle placard or tire i n
flat ion pressu re labe l, you shou ld dete rm ine
the p roper t ire inflation p ress ure fo r th ose
t ir es).
As an added safety feature , your ve hicle has
been equipped with a tire pressure mon ito ring
system ( TPMS) that illum inates a low ti re
pressure te lltale when one or more of your
tires is significant ly under -inflated . Acco rding
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 ability.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv
er's respons ibility to maintain co rrect tire
pressure, even if under-inflation has not
rea ched the leve l to tr igger illum inat ion of the
T PMS low tire p ressure tellta le .
Your vehicle has also been equipped with a
T PMS ma lfunction indicator to ind icate when
the system 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 ..,_

A WARNING 1= •
-If the tire pressure indicator appears in
the instrument cluster d isplay, one or
more of your tires is s ignificantly under
inflated. Reduce your speed immediately
and avoid any hard steering 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 indicated on the vehicle's tire
pressure label¢
page 247. Driving on a
signif icantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to impair the vehicle's handling and stop
ping abi lity .
- The driver is responsible for ma inta ining
the cor rect t ire pressures. You must
check the t ire pressures regularly.
- Under certain cond itions (such as a spor
ty driving style, w inter condit ions or un
paved roads), the pressure monitor ind i
c ator may be de layed.
- Ask your author ized Audi dealer if run
flat tires may be used on your veh icle.
You r vehicle registrat ion becomes inva lid

ted. Damage to your vehicle o r acc idents

@ Tips
- The t ire pressure monitoring system
stops working when there is an ES C/A BS
malfunction.
- Using snow chains may resul t in a system
malfunction.
- The t ire pressure moni toring sys tem on
you r A udi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall ¢
