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
vehicles with all wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory installed 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 fitted
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 275.
.&_ WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious persona l in­
Jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly 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 being 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 tor­
que of the wheel bolts 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
90 ft lbs . (120 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bolts
diagonally . After changing a wheel, the
torque must be checked as soon as possi­
ble with a torque wrench -preferably by an
authorized Audi dealer or qualified work­
shop.
Low aspect ratio tires
Your Audi is factory -equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road feel
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 indicated
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
tread width expressed in percentage. Conven­
tional tires have a height/w idth rat io of 60 or
more.
The performance of low-aspect-ratio tires is
particularly sensitive to improper inflation
pressure. It is therefore important that low
aspect ratio tires are inflated to the specified
pressure and that the inflation pressure is
regularly checked and maintained. Tire pres­
sures should be checked at least once a
month and always before a long trip
¢ page 237, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact with potholes, curbs, gul lies
or ridges on the road, particularly if the tire is
underinflated . ..,.

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 . ..,.

250 Tire s and wheel s
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 a lternate tires or wheels on the vehi ­
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunct ion
tellta le afte r 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.

Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.

I
F ig. 181 Display : underinflatio n warning
Using the ABS sensors, the tire pressure moni­
toring system compares the t ire tread circum­
ference and vibration characteristics of the in­
d iv idual tires . If the pressure decreases in one
or more tires, th is is indicated in the instru­
ment cluster w ith a
IE warning symbol and a
message¢
fig. 181 . The driver message in the
display goes out after 5 seconds. The driver
message can be displayed again by pressing
the
! SE T! button. If on ly one tire is affected,
the display will indicate its pos it ion.
The tire pressure monitoring system must be reset via radio or MMI * each time the pres­
sures are adjusted (e. g . when switching be ­
tween partia l and full load pressure) or after
changing or replacing a t ire on your vehicle
¢
page 251 . The TPMS indicator only moni­
tors the tire pressure that you have prev iously stored
. You can find the recommended tire
pressures for yo ur vehicle on the label on driv­
er's side B-pillar ¢

A WARNING
=
-If the tire pressure indicator appears in
the instrument cluster display, one or
more of your t ires is sign ificant ly under­
inflated. Reduce your speed immediately
and avoid any hard steer ing or braking
maneuvers. Stop as soon as possib le and
check the tires and their pressures. In­
flate the tire pressu re to the prope r pres­
sure as indicated on the vehicle's tire
pressu re labe l¢
page 235. D riving 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 .
- The driver is responsible for ma inta ining
the correct tire 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
cator 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 invalid
if you use these tires when not permit­
ted. Dam age to your veh icle or a cc iden ts
cou ld also resu lt.
@ Tips
- The t ire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- The t ire pressure monitoring system on
you r Audi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall¢
page 242. We recom­
mend using these t ires .
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
radio or MMI* .
.,. Before resetting the TPMS, the current p res­
s u res of all four tires must correspond to
the specified val ues . Adjust the tire pressure
