New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper knowledge and are equipped with
the required tools and replace­ ment parts .
.,.. New tires do not yet have the
optimum gripping properties.
Dr ive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires.
.,.. Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels .
.,.. Do not replace tires individually.
At least replace both tires on the same axle at the same time.

.,.. Audi recommends that you use
Aud i Orig inal Tires. If you would
like to use different tires, please
note that the tires may perform
diffe rently even if they are the
same size

.,.. If you would like to equip your
vehicle with a tire/rim combina ­
tion that is different from what
was installed at the facto ry, con ­
sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur­
chase
c:::> & -
The spare tire* is different from the regular tires installed on the
vehicle -for example, if winter
tires or wide t ires are installed -
so only use the spare tire* tempo ­
rarily in case of emergency and
drive carefully while it is in use . It
should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, all
four wheels must be equipped
with tires that are the same brand and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds . For this rea­
son, in case of emergency, only
use a spare tire* that is the same .,..

circumference as the regular
tires .
8,_ WARNING , -
-Only use tire/rim combina-
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more
than six years old when abso­
lutely necessary and drive
carefully when doing so.
Wheels
-Do not use run-flat tires on
your vehicle. Using them when
not permitted can lead to ve­ hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

tor
Tire wear
Check the tires regularly for wear .
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear .
-Have an authorized Audi dealer
or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear.
263
..

Wheels
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel.
If you do not, the tires and other
vehicle components could wear
more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread
pattern, which are bars that are
1/16 in (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running direc­
tion¢
fig . 197 . The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
The tires have reached the mini­ mum tread depth
l) when they
have worn down to the tread wear
indicators . Replace the tires with
new ones ¢A.
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the tires,
install the t ires from the rear axle
on the front axle and vice versa .
This will allow the tires to have

approximately the same length of
service life.
For unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢page 286.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hidden. Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage . If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­ er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed.
8_ WARNING
Tread that has worn too low or different tread depths on the
tires can reduce driving safety.
This can especially have a nega­
tive effect on handling, on the risk aquaplaning when driving
through water, when driving ,..

Wheels
rims yourse lf, because this increases the risk
of an accident.
Winter tires
W inter tire s significan tly improve the vehicle 's
handling when driving in w inter condi tions. Be­
cause of the ir construction (width, compound,
tread pattern) , summe r tires p rovide less trac­
tion o n ice and snow.
.. Use w inter t ires o n all four wheels .
.. Only use w inter t ires that are approved for your
vehicle .
.. Please note that the maximum permitted
speed may be lower with winter tires
¢ & -An
a utho riz ed Aud i dea le r o r authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed fo r you r tires.
.. Check the tire pr essu re after installing whee ls
¢ page 265.
The effectiveness of winter tires is reduced great ­
ly whe n the tread is wor n down to a depth of
0 .157 in (4 mm). The character istics of winter
tires also decrease great ly as the tire ages, re­
gardless of the remaining tread.
A WARNING
- Never dr ive faste r than the maxim um per ­
mitted speed for your t ires . This cou ld cause
the tires to heat up too much. This increases
t h e risk of an a cciden t be ca use i t can c ause
t h e tire to burst.
- Always adapt yo ur driv ing to t he r oad and
t ra ffic conditions. Drive ca refully and red uce
yo ur sp eed on icy or slippery roads. Even
winte r tires can lose traction on black ice .
@ For the sake of the environment
Reinstall su mme r tir es at the approp ria te
t ime, because they provide bet ter ha ndling
when ro ads are free of snow a nd ice. S ummer
t ires cause less road noise, ti re wea r and fuel
consumption.
270
(D Tips
You can also use a ll season tires instea d of
winter tires . Please note that in some coun­
tries where winter tires are required, on ly
winter tires w it h the
& symbol may be per­
mitted.
' Snow chains
S now cha ins not on ly improve the driv ing in win­
te r road cond it io ns, but a lso the b raking .
.. On ly install snow chai ns on the front wheels .
T his applies also to vehicles with all wheel
dr ive*.
.. Check and co rrect t he seating of the snow
chains after driving a few feet, if nece ssary. Fol­
low t he inst ructions from the m anufac turer.
.. Note the max imum speed of 3 0 mph (50 km/
h). Note the local regulations.
U se of snow c hains is only permitte d wit h cert ain
rim/ tire comb inat ions due to technical reasons.
Check with a n authorized Audi dealer or author ­
i zed Audi Service Facility to see if you may use
snow chains.
You m ust remove the snow chains on roads wi th­
out snow . Otherwise, you co uld impair driving
ability and damage the t ires .
A WARNING
Using incor rect snow chains or installing snow
cha ins incor rectly can result in loss of vehicle
control, which increases the risk of an acci­
dent .
(D Note
-Snow chains can damage the rims/wheel
covers* if the c hains come into direct con­
tact with them. Remove the w heel covers *
first . Use coated snow cha ins .
- Us ing snow c hains that add more tha n 0.53
in (13,5 mm) of height can seve rely damage
the whee l housings and o ther vehicle com­
ponents .

Wheels
Tread wear
The
tread wear grade is a compara tive ra ting
based on the wear rate of the t ire when tes ted
under contro lled conditions on a specified gov­
ernment test course.
F or examp le, a tire graded 150 would wear one
and one half (11/2) t imes as well on the govern­
ment course as a tire graded 100 .
The rela tive perfo rman ce of t ires depe nds upon
t he act ua l condi tions of their use, howeve r, and
may depart signif icant ly from the norm due to
variations in d riving hab its, service practices and
d ifferences in road characteristics and climate .
T raction
The
tra ction g rades, from highes t to lowes t, are
AA, A, Band
C. T hose gr ades represen t the t ire's
ab ility to stop on wet pavement as meas ured un ­
der controlled conditions on specified govern­ m ent test sur faces of asphalt and conc ret e. A tire
marked C may have poor traction performance
¢ &, .
Temperature The
temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to d iss ipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate ­
rial of the tire to degenerate and red uce tire life,
and excess ive temperature can lead to sudden
tire failure ¢&, .
The gra de C corresponds to a leve l of perform­
ance which a ll passenger ca r tires must meet un­
der the Federa l Moto r Vehicle Safety Standard
No. 109. Grades Band A represent higher leve ls
of performance on the laborato ry test wheel than
the m in imum required by law .
A WARNING
-
The traction grade ass igned to this tire is
based on straight -ahe ad braking t ract ion
t e sts, and does not include a ccele rat ion, cor­
nering, hydrop laning o r peak tract ion charac­
teristics .
272
A WARNING
--
The temperat ure grade for th is tire is estab­
lished for a tire that is properly inflated and
n ot overloaded . Excessive speed, underinfla­
tion, o r excessive load ing, either separately or
in comb ina tion, can ca use hea t bu ildu p and
possib le tire f ailure.
A WARNING
Tempe rature g rades apply to tire s th at are
p rope rly inflated and not over o r underinfla t­

Tire pressure monitoring
system
ill General notes
E ach tire, including the spare (if p rov ided),
shou ld be checked monthly when cold and in flat ­
ed to the inflat ion press ure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure labe l. (If your veh icle has
tires of a different size than the size ind icated on
the ve hicle placard or tire inflat ion press ure la­
bel, you sho uld dete rm ine the proper t ire infla­
tion press ure for those tires).
As a n added safety feature, your vehicle has been
equipped with a tire pressure mon itor ing system
(TPMS) that illuminates a low tire p ressure tell ­
ta le when o ne or mo re of your tires is s ignificant­
l y unde r-inflated. According ly, w hen the low t ire
pressure tell tale illum ina tes, you sho uld stop and
c h ec k yo ur t ires as soon as possib le, and inf late
t h em to the proper p ressure . Dr iving on a sign ifi ­
cant ly under-inflated tire ca uses the tire to over­
heat and can lead to tire fa ilure. Und er- inflation
also red uces fue l eff iciency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability .
P lease note that the TPMS is not a s ubstitute fo r
proper tire maintenance, and it is the dr iver 's re­
spons ibility to main tain correct t ire pressure,
even if under -in flat io n has not reached the level
to trigge r illumination of the TPM S low t ire pres-
su re te lltale . .,.

Vl c:o
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi ­
mately one minute and then remain continuously
illuminated . This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists .
When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function properly.
If the Tire Pressure Monitoring System
indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction .
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumfer­
ence and vibration characteristics of the individu­
al tires. If the pressure changes in one or more
tires, this is indicated in the Infotainment system
display w ith an indicator light
RE and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
c::;, page 274 . The tire pressure moni­
toring system only monitors the tire pressure you have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢ page 265, fig. 199.
Wheels
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if :
- the tire pressure in one or more tires is too low.
- the tire has structural damage.
- the tire was replaced or the tire pressure was
changed and it was not stored
c::;, page 274.
- the spare tire* is installed .

mm (Tire Pressure Monitoring System) Tire
pressure: malfunction! See owner's manual -If
mm appears after switching on the ignition or
while driving and then the indicator light
RE in
the instrument cluster also starts to blink for
about one minute and then stays on permanent­
ly, there is a system malfunction. Try to store the
correct tire pressures
c::;, page 2 74 . If the indica­
tor light does turn off or turns on again after a short period of time, drive to an authorized Audi
dealer or authorized Audi Service Facility immedi­
ately to have the malfunction corrected.
A WARNING
..-
- If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steering or braking maneu­
vers. Stop as soon as possible and check the
tires and their pressure.
- The driver is responsible for maintaining the
correct tire pressures . You must check the
tire pressures regularly .
- Under certain conditions (such as a sporty
driving style, winter conditions or unpaved
roads), the pressure monitor indicator may
be delayed.
- Do not use run-flat tires on your vehicle . Us­
ing them when not permitted can lead to
vehicle damage or accidents.

Care and cleaning
wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­ ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter. This in­
creases the risk of an accident. The brakes
must be dried first with a few careful brake
applications.
(D Note
- If you wash the vehicle in an automatic car
wash, you must retract the extendable rear
spoi ler* if necessary, and fold the exterior
mirrors in to reduce the risk of damage.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function .
- To reduce the risk of paint damage, do not
wash the vehicle in direct sunlight. -
To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or similar items.
- Matte finish painted vehicle components:
- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect.
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved.
@ For the sake of the environment
Only wash the veh icle in facilities spec ially de­
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.
