204 Tire s and wheel s
This also improves the vehicle's braking
performance and reduces stopping distances .
Summer tires provide less g rip on ice and
snow.
W inter t ires (snow t ires) must always be fitted
on all four wheels.
Compat ible tire pressure mon itoring sensors
must be installed on all four winter tires for
the tire pressure monitor ing system to func­
tion properly ~
page 201 .
Ask your authorized Aud i dea le r or qualified
workshop for permitted
wint er tire sizes. Use
on ly radia l wi nte r tires .
W inter t ires lose the ir effectiveness when the
tread is worn down to a depth of 0 .157 inch
(4 mm).
Only drive with winter tires under winter con­
d itions. Summer tires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C).
Please always remember that w inter t ires may
have a lower speed rating than the t ires origi­
na lly installed on your vehicle at the t ime it
was manufactured. Please see~
page 200,
Speed rating (letter code)
for a List ing of the
speed rat ing letter codes and the maximum
speed at wh ic h t he t ires ca n be dr iven .
The speed rating letter code
( ~ page 192) is
on the s ide wall of the tire~
page 199 .
A WARNING
Winter tires have maximum s peed limits
th at may be lowe r than you r vehi cle's m ax­
im um speed. Always know the maxim um
speed befo re d riving off . Never d rive faster
than the speed permitted for your specific
w inte r tires. This will cause damage to the
tires leading to an accident and serious
personal in jury to you and yo ur passen­
gers.
A WARNING
Dr iv ing faster than the maximum speed
for which the w inter t ires on your vehicle
-
were designed can cause t ire fail ure in­
cluding a blowout and sudden deflation,
l oss of contro l, crashes and ser ious per­
sona l injuries. Have worn o r damaged tires
r eplaced immediately .
- W inter tires have maximum speed rating
that may be lower than yo ur vehicle 's
maximum speed.
- Never d rive faster than the speed for
which the w in ter or othe r tires installed
on yo ur vehicle a re rated .
A WARNING
-Always ad just your dr iv ing to the road and
traffic condit ions . Never let the good ac­
ce ler ation o f the w in ter t ires and a ll-wheel
d rive tempt yo u into t aking extra risks. Al­
ways remember:
- W hen braking, an all-wheel drive veh icle
handles in the same way as a front drive
vehicle .
- D rive c arefully and redu ce your spee d on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions .
@ For the sake of the environment
Use summer tires when weather condi­
tions permi t. T hey are qu iete r, do no t wear
as quickly and reduce fuel consumpt ion .
Snow chains
Snow chains may be fitted only to the rear
whee ls, and on ly to certain tire sizes . Ask your
authori zed Aud i dea ler on which tire si zes
snow chains ca n be used .
The snow chains must have low -profi le links
and must not be th icker than 0.53 inch
(13 .5 mm), includ ing the lock.
Remove whee l center covers before putt ing
snow c hains on your vehicle
~ CD . For safety
reasons cover caps must then be f itted over
the wheel bolts. These are available from au­
thorized Audi dea le rs.

illuminates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significantly under- inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation a l­
so reduces fuel efficiency and tire tread life,
and may affect the ve hicle's handling and
stopping ab ility .
Please note that the TPMS is not a substitute
for proper t ire maintenance, and it is the dr iv ­
e r' s responsib ility to ma inta in correct t ire
p ressure, even if under- inflation has not
reac hed the level to t rigge r illumination of the
TPMS low tire pressure telltale .
Your veh icle has also been equ ipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indi cato r i s combined wi th
the low ti re pressure tell ta le . When the sys­
tem detec ts a malf unction, the te lltale will
flash for approximately one minute and t hen
remain cont inuo usly illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction ex ists.
When the malfunctio n indicator is ill uminat­
ed, the system may not be able to detect or
signal low t ire pressure as intended . TPMS
malfunct ions may occur for a variety of rea­
sons, includi ng the installat io n of rep lace­
ment or alternate tires o r wheels on the veh i­
cle that prevent the TPMS from funct ion ing
p roperly . Always chec k the TPMS malfunct ion
t ellt ale after replacing one o r more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly .
Introduction
T he tire pressure monitoring system monitors
oir pressure in all four road wheels while the
vehicle is moving .
As soon as the tire pressure monitoring sys­
tem senses a significant loss of air pressure in
one or several ti res, text messages and yellow
symbo ls appear in the instr ument cluster d is­
p lay to alert the driver. T he
RE warning light
Tire s an d wheel s 207
in the instrument cluster comes on when the
tire is significant ly underinflated .
T he wa rni ng lig ht
RE also ill umi nates in the
case of a system malfun ct ion.
Be awa re that t ire pr essure is a lso dependent
o n the tempe ratu re of the t ire. For eve ry 18 ° F
(10 °C) incre ase in tire temper ature, tire pres­
s ur e increases by about 1.5 psi (0 .1 bar). The
ti re warms up while the vehicle is moving and
tire press ure rises . So you sho uld ad just tire
pressure only when they a re
cold, when the
temperature of the tires is ro ughly the same
as the ambient a ir temperature.
In order to keep the tire p ress ure monitoring
system p roperly ca librated, t ire pressu re on
a ll four tires sho uld be checked at regu lar in­
terva ls.
The tire pressure is shown on the label located
on the dr iver's side B-pillar (v is ible when the
door is open).
A WARNING
When t he tire pressure mo nitoring system
war ning light is lit, one o r more of your
tires is s ignificantly under-infla ted . You
should stop and check you r tires as soon as
possib le, and in flate t hem to the proper
p re ssur e a s in di cate d on the ve hicle's tir e
press ure label
¢page 19 3. D riving on a
significantly under -inflated ti re causes the
tire to over heat and can lead to tire failure.
Under-inflat ion also is like ly to impair the
vehicle's handling and stopping ab ility.
@ For the sake of the environment
D riving wit h un der -inflated tires red uces
fuel efficiency an d tire t read life.
(D Tips
- Ea ch tire should be chec ked monthly
w hen the temperature of the tires is
about the same as ambient a ir tempera­
t u re and set to the recommended infla­
tion press ure as specified on the tire
pressure label
