What you can do to avoid tire and rim
damag e
Low aspect ratio tires can be damaged more easi ­
ly by impact with potholes, curbs, gullies or
ridges on the road, part icularly if the t ire is un­
derinflated.
In order to minimize the occurrence of impact
damage to the tires of your vehicle, we recom­ mend that you observe the following precau­
tions:
- Always maintain recommended inflation pres­
su res. Check your tire pressure every 2.000
miles (3.000 km) and add air if necessary .
- Drive carefu lly on roads w ith potholes, deep
gull ies or r idges. The impact from driving
through or over such obstacles can damage
your tires . Impact with a curb may also cause
damage to you r tires .
- After any impact, immediately inspec t your
tires or have them inspected by the nearest au ­
thorized Audi dealer. Replace a damaged tire as soon as possib le.
- Inspect you r tires every 2 .000 miles (3 .000 km)
for damage and wear. Damage is not always easy to see. Damage can lead to loss of ai r and
u nderinflation , which cou ld eventua lly cause
t ir e fa ilure. If yo u be lieve that a tire may have
been damaged, rep lace the tire as soon as pos ­
sible .
- T hese tires may wear more q uick ly than others .
- Please a lso remembe r that, wh ile these ti res
deliver responsive handling, t hey may ride less
com fortab ly and make more noise than other
choices.
R educed performance in winter /cold season
condit ions
All ti res are designed for certain pu rposes . The
low aspect ratio, u ltra high performance tires
originally insta lled on your vehicle are intended
for maximum dry and wet road performance and handling. They are not suitable for cold, snowy or
icy weather cond itions . If you drive under those
circumstances, you should equip your vehicle
with all-season or winter tires, which offer better traction under those conditions. We suggest you

u se the recommended snow or all-season tires
specified for your vehicle, or their equivalent.

Tire pressure monitoring
system
General notes
E ach tire, incl uding the spare ( if prov ided),
shou ld be checked monthly when co ld and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placa rd or
tire inflation pressure labe l (If your vehicle has
tires of a different s iz e than the si ze indicated on
the ve hicle placard or tire inflation pressure la­
bel, you should determine the proper t ire infla ­
tion pressure for those tires .) .
As an added safety feature, your veh icle has been
equipped with a tire pressure mon itor ing system
(TPMS) that illuminates a low t ire pressure tell­
ta le when one or more of your t ires is sign ificant­
l y unde r-inflated. According ly, when the low tire
pressure te lltale illuminates, you shou ld stop and
chec k yo ur ti res as soon as poss ible, and infla te
them to the proper pressure . Dr iv ing on a signifi­
cant ly under-inflated tire ca uses the t ire to over ­
heat and ca n lead to tire failure . Under-inflation
also reduces fuel effic iency and tire tread life,
and may affect the vehicle 's handling and stop­
ping abili ty .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
spons ibility to maintain correct tire pressure,
even if under-infla tion 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 malfunc tion indicator to indicate when the sys­
tem is not operat ing properly . The TPMS mal ­
funct ion indicator is combined with the low t ire
pressure te lltale. When the system detects a
malfu nction, the tellta le w ill flash for approxi­
mately one m inute and then remain cont inuo usly
i ll uminated. This seq uence 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 signa l
l ow tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of rep lacement or a lternate tires or
wheels on the vehicle that prevent the TPMS from functioning properly. Always check the
T PMS 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 .
Introduction
The tire pressure monitoring system monitors air
pressure in all four road wheels while the vehicle
is moving.
As soon as the tire pressure monitoring system
senses a s ignificant loss of a ir pressure in one or
several tires, text messages and ye llow symbo ls
appear in the instrument cluster display to a le rt
the driver. The
[I] warning light in the instru ­
ment cluster comes on when the tire is signifi ­
cantly underinflated .
The warning
light [l'J also illuminates in the case
of a system malfunction.
Be aware that tire p ressure is also dependent on
the temperat ure of the t ire. For every 18 ° F
(10 °() increase in tire temperature, tire pressure
increases by about 1.5 psi (0.1 bar) . The tire
warms up while the vehicle is moving and tire
pressure rises. So you shou ld adjust tire pressure
only when they are
cold, when the temperature
of the tires is roughly the same as the ambient
air temperature.
In order to keep the tire pressure monitoring sys­
tem properly calibrated, tire pressure on all four
tires should be checked at regular intervals .
The tire pressure is shown on the label located on
~ the driver 's side B-pillar (visible when the door is r--
~ open) .

A WARNING
-
When the tire pressure monitoring system
warning light is lit, one or more of your tires is
significantly under- inflated . You should stop
and check your t ires as soon as poss ible, and
i nflate them to the proper pressure as indicat­
ed on the vehicle 's t ire pressure label
¢ page 176. Driving on a significant ly 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
stopping ability.
@ For the sake of the environment
Driving with under -inflated tires reduces fuel
efficiency and tire tread life.
(D Tips
- Each tire should be checked monthly when
the temperature of the tires is about the
same as ambient air temperature and set to
the recommended inflation pressure as
specified on the tire pressure label
¢page 176.
- The tire pressure mon itoring system helps
the driver to keep an eye on tire pressures.
But the driver still has the responsib ility for
ma inta ining the correct tire pressure.
- Tire pressure must only be adjusted when
the temperature of the tires is about the
same as amb ient air temperature.
- When tires are replaced, the sensors and
valves should not be exchanged. The valve
core, nut, valve seal ing and seal washer (re­
placement kit) needs to be replaced. If nec­
essary, the valve and the wheel electronics
have to be replaced.
- The tire pressure mon itoring system on your
Audi was calibrated using tires with "RO"
identification. We recommend using these
tires .
- If you sho uld put different wheels and tires
on your vehicle (e .g. winter whee ls and
tires), you must be certain that the wheels
197

and tires are compatible with the tire pres­
sure monitoring system. Otherwise the sys­
tem will register a malfunction and a fault message will be displayed. For more infor­
mation, contact your authorized Audi deal­
er.

the display and them indicator light
turns on. If this happens, repeat the proce­
dure.
- Do not store the tire pressure if there are
snow chains on the tire.
TPMS Tire pressure monitoring system
malfunction
A malfunction can have various causes.
If the [I] warning light in the instrument cluster
flashes for approximately one minute and then
remains continuously illuminated and additional­
ly
the m symbol appears in the display, the tire
pressure monitoring system is not available. The
198
text Tire pressure! System malfunction appears
in the display. This can have various causes.
- A wheel sensor or other component may have
fai led.
- During initialization the system has detected
more than 4 wheels on the vehicle, for example
while driving next to another car with a tire pressure monitoring system.
- Audi replacement parts were not used.
- If snow cha ins are being used, system function
can be compromised due to the shielding prop­
erties of the chains .
- The tire pressure monitoring system may not
be available because of a rad io malfunction.
- Transmitters with the same frequency, such as
radio headphones in the vehicle or radio equip­
ment, can cause a temporary disruption of the
system through excessive electromagnetic
fields .
- Eliminate the interference if you can and then
proceed as follows: Turn off the engine for 20
minutes. Then drive another 10 minutes.
If the
warning light comes on again, you should con­
tact your authorized Audi dealer immediately
to have the problem corrected.
- Do not use commercially available tire sealants.
Otherwise, the electrical components of the
tire pressure monitoring system will no longer
work properly and the sensor for the tire pres­
sure monitoring system will have to be replaced
by a qualified workshop.
