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
e d.

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 .

RE-Loss of pressure in at least one tire c::;, &,.
Check the tires and replace or repair if necessary.
Check/correct the pressures of all four tires and
store the pressure again in the Infotainment sys­
tem

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.

emergency flashers on and use other warn­
ing devices to alert other motorists.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipp ing off the jack,
always fully set the parking brake and block
the wheel diagona lly opposite the wheel be­
ing changed . When one front wheel is lifted
off the ground, placing the Automatic
Transmission in P (Park) will
not prevent the
vehicle from moving.

-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the whee l.
Unidirectional tires
A unidirectional tire profi le is identified by arrows
that point in the runn ing direction on the tire
s idewall. You must always adhere to the speci­
fied running direction. This is necessary ensure
the tire's optimum performance in regard to ad­
hesion , running noise, friction and hydroplaning.
To benefit fully from the advantages of the uni­
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.
