the risk of an accident. Read and follow the important safe
ty precautions in ¢ page 267,
Tires and vehicle load limits.
-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con
trol.
- Incorrect tire pressure in
creases tire wear and has a
negative effect on driving and

Please note that the information

creases the risk of an accident.
(D Note
Replace lost valve caps to re
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in
creases fuel consumption.
(D Tips
Audi recommends using the
tire pressure specified for a normal load
¢ table on
page 267
or for a full load
when the vehicle is partially
loaded.
Make sure that the tire designa
tion on your tire matches the des
ignation on the tire pressure label
and the tire pressure table.
The following table lists recom
mended tire pressures in cold
tires according to the load and
the size of the tires installed.

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

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-
