the wheel bolts. These are available from au
thorized Audi dealers.
A WARNING
Using the wrong snow chains for your vehi
cle or installing them incorrectly can in
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes. Always make sure to follow the in
structions provided by the snow chain
manufacturer .
- When driving with snow chains, never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces
sary. Follow the instructions from the
snow chain manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer
tain roads, this normally also applies to ve
hicles with all-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel 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 .
Tires and wheels 199
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r:!> page 221.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious personal 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 vehi
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 wheel bolts is
90 ft lb (120 Nm) with a tolerance of ± 7 .4
ft lb( ± 10 Nm). Torque wheel bolts diago
nally. After changing a wheel, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author
ized Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been selected specifically for your model for their superb performance, road feel
and handling under a variety of driving
IJ,,

conditions. Ask your authorized Audi dea ler
for more details.
The low aspect ratio of these tires is indicated
by a numeral of 55 or less in the tire's size
designation. The numera l represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven
tional tires have a height/width ratio 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 reg
ularly checked and maintai ned. Tire pressures
should be checked at least once a month and
a lways befo re a long t rip
~ page 189, Check
ing tire pressure.
What you can do to avoid tire and rim
damage
L ow aspect ratio tires can be damaged more
eas ily by impact with potholes, curbs, gullies
o r ridge5 on the road, particu larly if the tire i5
underinflated.
I n order to minimize the occurrence of 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 air if neces
sary .
- Drive carefully 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
authori zed Aud i dealer. Rep lace a damaged
t ir e as soon as possible.
- Inspect your tires 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 t ire failure . If you believe that a tire
may have been damaged, rep lace the
tire as soon as possible.
- These tires may wear more quickly than oth
ers.
- Please also remember that, while these tires
delive r responsive handling, they may ride
less comfortably and make more noise than
other choices .
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance
t ir es or iginally installed on your vehicle are in
tended for maximum dry and wet road per
formance and handling . T hey are not suitable
for cold, snowy or icy weather conditions . If
you drive under those c ircumstances, you
should equ ip your vehicle with winter tires,
which offer better traction under those condi
tions . We suggest yo u use the recommended
snow tires specified for your vehicle, or their
equivalent.
Refer to~
poge 197 for more detailed infor
mation regarding winter tires.
Ti re pressure
monitoring system
General notes
Eac h tire, including the spare (if provided),
shou ld be checked mon thly when cold and in
flated to the inflat ion pressure recommended
by the ve hicle manufacturer on the vehicle
placard or tire inflation pressure labe l (If your
vehicle has tires of a different si ze than the
s ize indicated on the vehicle placard or tire in
flat ion pressure label, you should determine
the proper t ire in flation pressure for those
t ir es .) .
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illum inates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Acco rding
ly, when the low tire pressure telltale illumi
nates, you shou ld stop and check you r tires as
Ill>-
Page 203 of 236

soon as possible, and inflate them to the
proper pressure . Driving on a significant ly un
der-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation a l
so reduces fuel efficiency and tire tread l ife,
and may affect the veh icle 's handling and
stopping ab ility.
Please note that the TPMS is not a substitute
for proper t ire maintenance, and it is the dr iv
er's responsib ility to ma inta in correct t ire
p ress ure , even if under- inflation has not
reached the leve l to t rigger illumination of the
TPMS low tire pressure telltale .
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indicate when
the system is not ope rating properly. The
TPMS malfunc tion indica to r i s combined wi th
the low t ire pr essu re tellta le. When the sys
tem detec ts a ma lf u nct ion, the te lltale will
flash for approximately one minute and then remain continuo usly ill uminated . This se
q uence will continue upon subsequent vehicle
start-ups as long as the malfunction ex ists.
When the malfunction indicator is ill uminat
ed, the system may not be able to detect or
signa l low t ire pressure as intended . TPMS
malfunct ions may occ ur for a variety of rea
sons, including the ins talla tio n of replace
ment or a lternate tires o r whee ls on the veh i
cle that prevent the TPMS from funct io ni ng
p roperly . Always check the TPMS malfunct ion
t ellta le afte r replacing one o r more t ires or
wheels o n your veh icle to ensure tha t the re
p lacemen t or a lternate tires and wheels allow
the TPMS to continue to function properly .
Introduction
The tire pressure monitoring system monitors
air pressure in all four road wheels while the
vehicle is moving .
As soon as the tire pressu re mo nitor ing sys
tem senses a s ignificant loss of a ir pressure in
one or severa l ti res, text messages and yellow
symbo ls appear in the instr ument cluster dis
p lay to alert the driver. The
[ti warning light
Tire s an d wheel s 201
in the instrument cluster comes on when the
ti re is significant ly underinflated .
T he wa rni ng lig ht
[ti also illu minates i n the
case of a system mal funct io n.
Be aware that t ire pressure is a lso dependent
o n the tempe ratu re of the t ire. For eve ry 18 ° F
(10 °C) incre ase in tir e te mper ature, tire pres
s u re inc reases by about 1.5 psi (0 .1 bar). The
ti re warms up while the ve hicle is moving and
tire p ress ure rises . So you sho uld ad just tire
pressure only when they a re
cold, when the
temperature of the tires is ro ughly the same
as the ambient a ir temperature.
In order to keep the tire press ure monito ring
system p roperly ca librated, t ire press ure on
all four tires sho uld be checked at regu lar in
terva ls.
The tire pressure is shown on the label located
on the dr iver's side B-pillar (v is ib le when the
door is open) .
A WARNING
When the tire pressure mo nitoring system
war ning light is lit , one o r m ore of your
tires is s ignificantly under-infla ted . You
shou ld stop and check your tires as soon as
pos sib le, and in flate t hem to the proper
p ress ure a s in dic ate d on the ve hicle's ti re
p ress ure lab el
¢page 187. Driving on a
significantly under -inflated ti re causes t he
tire to over heat and can lead to tire failure .
Under-inflat ion also is like ly to impair the
vehicle's handling and stopping ab ility.

202 Tire s and whee ls
- The tire pressure monitoring system
helps the driver to keep an eye on tire
pressures. But the driver st ill has the re
spons ibility 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 tempera
ture.
- When t ires are replaced, the sensors and
valves should not be exchanged . The
valve core, nut, valve sealing and seal
washer (rep lacement kit) needs to be re
placed. If necessary, the valve and the
whee l electronics have to be rep laced.
- The tire pressure monitoring system on
your Audi was calibrated us ing tires w ith
"RO" identification. We recommend us
ing these tires.
- If you should put different whee ls and
ti res on yo ur vehicle (e.g. w inter wheels
and tires), yo u m ust be certain that the
whee ls and tires are compatible with the
tire pressure monitoring system . Other
wise the system w ill reg ister a ma lfunc

After a tire repair, have the sealant bottle
replaced at a dealership. This restores full
functionality to the Tire Mobility System .
What should I be
aware of when
changing a tire?
Tires with unidirectional tread design
-
Tires with unidirectional tread design must be
mounted with their tread pattern pointed the
right direction.
A unidirectional tire can be identified by ar
rows on the sidewall, which point in the direc
tion of the rotation. You must follow the
specified direction of rotation. This is necessa
ry in order for these tires to develop their op
timum characteristics regarding grip, road
noise, wear, and hydroplaning .
