@ 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
length 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 291.
.&_ WARNING
Improperly tightened or maintained wheel
bolts can becom e loose caus ing loss of
cont ro l, a co llision and serious persona l in
Jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clea n so the
w heel bolts can t urn easily and be prop
erly t ightened .
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose while d riving if greased or
oi led, even if tightened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Always maintain the co rrect tighten ing
torq ue for the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor
que of the wheel bolts is too low, they
can loosen and come out when the vehi
cle is moving. If the tightening torque is
too high, the whee l bolts and threads
Tire s an d wheel s 263
can be damaged and the whee l can be
come loose.
(D 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) . Torq ue whee l bolts diago
nally. After changing a whee l, the torq ue
must be checked as soon as possible with a
torque wrench -preferably by an author
i zed Audi dealer or qualified workshop.
Low aspect ratio tires
You r Aud i is facto ry-equ ipped w it h low aspect
ra tio tires. These tires have been tho ro ughly
tested and been se lec ted spe cifically for you r
model for their superb perfo rmance, road fee l
and handling under a variety of driving condi
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or le ss in the tire's s ize
designation. The numera l represents the ratio
of the t ire's sidewa ll height in relation to its
tread width expressed in percentage. Conven
tiona l tires have a he ight/w idth rat io of 60 or
more .
The performance of low-aspect -ra tio tire s is
particularly sens it iv e to improper inflation
pressure. It is therefore important that low
aspect ratio t ires are inflated to the specified
pre ssure and that the inflation pressur e is
regularly che cked and maintain ed. Tire pre s
s ures should be checked at least on ce a
m onth and alwa ys before a long trip
¢ page 2 52, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damage d mo re
easily by impact w ith potholes, curbs, g ull ies
or ridges on t he road, partic ularly if the tire is
u nderinflated.

264 Tire s and wheel s
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 possible .
- 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 underinflation, wh ic h could event u
ally cause t ire 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 wea r more qui ck 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 choices.
R educed p erformance in winter /cold
sea son conditions
A ll tires are designed for certain purposes .
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in
tended for max imum dry and wet road per
f ormance 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 a ll-season tires specifie d
for your vehicle, or their equiva lent .

Tire pressure
monitoring system
ill General notes
Applies to veh icles: w ith tire pressure monito ring system
Each tire, incl uding the spare (if provided),
sho uld be checked monthly when co ld and in
flated to the inf lat ion 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 ize indicated on the vehicle placard o r tire in
flat io n pressu re label, you sho uld dete rmine
the p roper t ire infla tion p ressure fo r those
t ir es) .
As an added safety featu re, your ve hicle has
been equipped with a tire pressure mon itoring
system ( TPM S) that illum inates a low ti re
pressure te lltale whe n one or more o f you r
tires is signif icant ly under -inflated . Acco rding
l y, 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 u n
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under -inflation al
so reduces fuel eff ic iency and tire tread life,
and may affe ct 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 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 illuminat ion of the
T PMS low tire p ressu re tellta le .
You r vehicle has also been equipped with a
T PMS ma lf u nction indicator to ind icate when
the sys tem is not oper ating properly . T he
T PMS ma lfunction indicator is comb ined w ith
the low tire pressure te lltale. Whe n the sys
tem detects a malfunction, the telltale will
flash for approximately 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 t he malfunct ion exists . .,.
26 6 T ire s and whee ls
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
c> page 250. Driving on a
significantly 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 ability.
- T he driver is responsible for ma inta ining
the correct tire pressures. You must check the t ire pressures regular ly .
- Under certain cond itions (such as a spor
ty driving style, winter condit ions or un
paved roads), the pressure monitor indi
cator may be de layed .
- Ask your author ized Audi dealer if r un
flat tires may be used on your vehicle .
Your vehicle regist ration becomes invalid
if yo u use these tires when not permit
ted. Damage to your veh icle or accidents
cou ld also result.
- 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" identif ication on the
tire sidewall
c> page 257. We recom
mend using these t ires.
Reset tire pressure monitoring system
App lies to vehicles: with tire pressure monito ring system
If the tire pressure is adjusted, wheels are ro
tated or changed, the TPMS must be reset via
MMI.
