tread pattern), summer tires provide less trac­
tion on ice and snow.
.,. Use w inter tires on a ll fo ur wheels.
.,. Only use win ter tires that are approved for your
vehicle.
... Please note that the maximum permitted
speed may be lower with winter tires ¢,& .An
authori zed Aud i dealer or authori zed Aud i Serv­
ice F acility can inform you about the maximum
permitted speed for your tires .
... Check the tire pressure after installing wheels
¢ page 256 .
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .1 57 in (4 mm) . The character istics of winter
tires a lso decrease great ly as t he tire ages, re­
ga rdless of the remaining tread .
_& 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 . Th is increases
the risk of an acc ident because it can cause
the tire to burst.
- Always adapt yo ur dr iv ing to the road and
traff ic conditions. Drive carefully and red uce
your speed on icy or slippery roads. Even
winter tires can lose traction on black ice.
@ For the sake of the environment
Reinstall summer ti res at the approp riate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, t ire wear and fuel
consumption .
You can also use all season tires instead of
w inter t ires . Please note that in some coun­
tries where w inter t ires are required, only
w inter t ires with the
& symbol may be per­
m itted.
Snow chains
-
Snow chains no t only imp rove the d riving in w in­
ter road conditions, but also the braking.
Wh eel s
... On ly install snow chains on the front wheels.
This applies a lso to vehicles with a ll wheel
drive* .
... Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer .
... Note the maximum speed of 30 mph (SO km/
h) . Note the local regulations .
Use of snow cha ins is only permitted with certa in
rim/tire comb inat ions due to technical reasons .
Check with an authorized Audi dealer or author­
i zed Audi Se rvice Facility to see if you may use
snow c hains.
You must remove the snow chains on roads with­ out snow . O therwise, you co uld impair driving
ability a nd damage the t ires .
_& WARNING
Using incor rect snow chains or install ing snow
ch ains incor rec tly c an resu lt in loss of veh icle
control, which increases the risk of an acci­
dent .
(D Note
-Snow chains can damage the rims/wheel
cove rs* if the chains come into direct con­
tact with them . Remove the wheel covers*
first. Use coated snow chains.
- Us ing snow chains that add more tha n O.S3
in (13,S mm) of height can severe ly damage
the whee l housings and other vehicle com­
ponents.
(D Tips
When using snow chains, it may be usefu l to
switch on sport mode ¢

Low aspect ratio tires
Your Audi is factory-equ ipped with low aspect ra­
tio t ires . These tires have been thoroughly tested
and been selected spec ifically for your model for
the ir superb performance, road feel and handl ing
under a var iety of dr iv ing condit ions. Ask your au-
thorized Audi dea le r fo r more details . .,.

Traction
The traction grades, from highest to lowest, are
AA, A, B and
C. Those grades represent the tire's
ability to stop on wet pavement as measured un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete . 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 dissipate
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 reduce tire life,
and excessive temperature can lead to sudden
tire failure
c:> .& .
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard No.
109 . Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING
The traction grade assigned to this tire is
based on straight -ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics.
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded . Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.

Tire pressure monitoring system
ill General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size ind icated on
the vehicle placard or tire inflation pressure la­ bel, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant ­
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure . Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure, even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale .
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 .,.
