Sustained high temperature can cause the
materia l of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failure<=>,& .
The grade C corresponds to a level of perform­
ance which a ll passenger car tires must meet
under the Federa l Motor Veh icle Safety Stand ­
ard No.
109. Grades Band A represent higher
levels of performance on the laboratory test
wheel than the m inimum required by law .
A WARNING
The traction grade assigned to this t ire is
based on stra ight-ahead braking traction
tests, and does not include acceleration,
corne ring, hydrop lan ing o r peak traction
character istics .
A WARNING ,.,.____
The temperature grade for this tire is es­
tablished for a tire that is p roperly inflated
and not overloaded. Excessive speed, un­
derinflation, or excessive loading, either
separate ly or in combination, can cause
heat buildup and possible tire fa ilure.
Winter tires
Winter tires can improve vehicle handling on
snow and ice. At temperatures below 45 °F
(7 °C) we recommend changing to winter
tires .
In some heavy snow areas, loca l governments
may require true winter or "snow" tires, those
with very deeply cut tread. These t ires should
only be used in pairs and be installed on all
four wheels. Make sure yo u purchase snow
tires that are the same size and const ruct ion
type as t he other tires on your ve hicle.
If your vehicle is equ ipped with all -wheel
drive*, this will improve t ract ion during w inter
d riving, even wit h the standard tires. Howev­
e r, we strong ly recommend that you always
eq uip a ll four w heels on yo ur vehicle wi th cor­
rectly fitted win ter tires or a ll-season tires,
when winte r road conditions are expected . This also improves the veh
icle's brak ing per ­
formance and reduces stopping distances.
Summe r tires p rovide less gr ip on ice and
snow.
Winter tires (snow tires) must always be fitted on all fou r wheels .
Ask your authorized Audi dealer or qualified
workshop for perm itted
winter tire siz es. Use
o n ly rad ial winter t ires .
Winter tires lose their effectiveness when the
tread is worn down to a depth of
0 .157 inch
(4 mm).
Only drive w ith w inter t ires under winter con ­
ditions. Summer t ires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °() .
If you have a flat tire, see notes on spare
wheel
<=>page 257.
Please a lways remember that winter tires may
have a lower speed rating than the tires origi ­
nally installed on your vehicle at the time it
was manufactured. P lease see<=>
page 260,
Speed rating (letter code)
fo r a listing of the
speed rating lette r codes and the max imum
speed at which the tires can be d riven .
The speed rating letter code (<=>

c> page 257.
A WARNING ,.___
W inter t ires have maximum speed lim its
that may be lower than yo ur vehicle's max­
i mum speed. Always know the max imum
speed before dr iv ing off. Never dr ive faster
than the speed permitted for yo ur specific
winter tires . This wi ll ca use damage to the
tires leading to an accident and ser ious
personal injury to you and your passen­
gers.
A WARNING
'----
Driving faster than the maximum speed
for which the winter tires on your vehicle were designed can cause t ire failure in­
cluding a blowout and sudden deflation,

thro ugh or over such obstacles can damage
your tires. Impact with a curb may a lso
cause damage to your tires .
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Audi dea ler. Replace a damaged
t ire as soon as possible.
- Inspect yo ur 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 tire fa ilure . If you be lieve that a
t ire may have been damaged, replace the
t ir e as soo n as possible.
- T hese tires may wear more quickly than oth­
ers .
- Please also remember that, while these tires deliver respons ive handling, they may ride
less comfortably and make more no ise than
othe r cho ices .
Reduced perf ormance in winter /cold
season condition s
All t ires are des igned for certain pu rposes.
The low aspect ratio, ultra hig h pe rformance
tires orig inally installed on your veh icle are in ­
tended for maximum dry and wet road per ­
formance and handling . They are not s uitable
for cold, snowy or icy weather conditions. If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, which offer better traction under
those cond itions . We suggest you use the rec­
ommended snow or all-season tires specified
fo r your ve hicle, or their equ ivalent.

Tire pressure
monitoring system
U) General notes
Each t ire, includ ing the spare (if provided),
should be checked month ly when cold and in­
flated to the inflation pressure recommended by the vehicle manufacture r o n the vehicle
p lacard or tire inflation pressure label. (If yo ur
Tire s an d wheel s 267
vehicle has tires of a different size than the
size indicated on the vehicle placard or tire in­
flat ion pressure labe l, you sho uld determine
the proper t ire inflation press ure for those
tires).
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
ti res is significant ly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you shou ld stop and check you r tires as
soon as possib le, and inflate them to the
proper pressu re. Driving on a sign ifican tly un­
der -infla ted ti re causes the tire to overhea t
and can lead to tire fai lure . Under-inflation al ­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv­ er's respons ibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to tr igger illuminat ion of t he
TPMS low tire pressu re tellta le.
Your vehicle has also been equipped with a
TPMS malfunction indicator to ind icate when
the system is not operating properly. The
TPMS ma lfunction indicator is combined with
the low t ire pressure telltale . Whe n the sys­
tem detects a malfunction, the telltale will
flash fo r approximate ly one m inute and then
r em ain continuously illum ina ted . Thi s se­
quence will continue upon s ubsequent vehicle
start-ups as long as the malfunction exists .
When the malfunction indicato r is illum inat­
ed, the sys tem may no t be ab le to detec t or
s ignal low tire pressure as in tended . TPMS
malfu nctions may occur for a var iety of rea ­
sons, incl uding the insta llation of rep lace­
ment or a lternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning properly. Always check the TPMS malfunction
telltale after rep laci ng one or more tires or
whee ls on your vehicle to ensu re that the re­
placement o r alternate tires and wheels a llow
the TPMS to con tinue to funct ion p ro perly .

Tire pressure 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.
Fig. 200 Display : und erinflatio n warn ing
Fig. 201 Display: Syste m malfunction
Using the ABS sensors , the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
dividual tires.
If the pressure decreases in one
or more tires, this is indicated in the instru­
ment cluster with a warning symbol
[9] and a
message ¢
fig. 200.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad­
justed (e. g. when switching between partial
and full load pressure) or after changing or re­
placing a tire on your vehicle¢
page 269 . The
TPMS indicator only monitors the tire pres­
sure that you have previously stored. You can
find the recommended tire pressures for your vehicle on the label on driver's side 8-pillar

page 269. If the indicator light
does not turn off or if it turns on shortly
thereafter, immediately drive your vehicle to
an authorized Audi dealer or authorized repair
facility to have the malfunction corrected.
A WARNING
- If the tire pressure indicator appears in
the instrument cluster display, one or
more of your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
flate the tire pressure to the proper pres ­
sure as indicated on the vehicle's tire
pressure label¢
page 244 . Driving 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 maintaining the correct tire pressures. You must
check the tire pressures regularly. ..,
