signa l low tire pressure as intended. TPMS
malfunct ions may occur for a variety of rea­
sons, including the installat ion of replace­
ment or alternate tires or wheels on the veh i­
cle that prevent the TPMS from funct io ni ng
properly. Always check the TPMS malfunct ion
tellta le afte r replacing one or 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.

Run-flat ti res
Introduction
Applies to vehicles: with Run -f lat tires
Run-flat tires help keep you moving if a tire
goes flat.
Re inforced sidewalls give the tires run-flat ca­
pability if tire pressure is lost .
We recommend that r un-flat tires on ly be
m ounted on vehicles that were orig inally
equipped with these special tires at t he facto­
ry and have a Tire Pressure Moni toring Sys­
tem .
Run-flat tires can be identified by the letters
"RSC" on the tire sidewall.
If you do change the tires on your veh icle from
norma l to run- flat tires, you must b uy the
special rims required for run-flat tires, and the
T ire Pressure Monitor ing System must be re­
programmed by an authorized Aud i dealer o r
other qualified worksho p .
What do run-fl at tires do?
These special tires have r un-flat capabilities
that help keep you moving if a t ire loses pres­
sure and goes flat . Under favorable conditions
ti res can be dr iven
at least 30 miles (50 km) ,
but you mus t not dr ive faster than 50 mph Ill-

202 Tires and wheels
(80 km/h)
¢ page 202, Driving with run -flat
tires .
When it is not possible to continue
driving, even with run-flat tires?
- If the E lectronic Stabilization Control (ESC)
is not working or keeps coming on.
- If the Tire Pressure Monitoring System does
not work .
-If the tire has been severely damaged, in a
crash, for example. The tread can separate
from a damaged tire as the whee l turns , and
hit parts of the vehicle , such as the fuel tank
filler neck, fuel lines or brake lines.
- Do not continue driving if severe vibration
occurs or if the tire starts to smoke because
the tire is running hot.
- Do not continue driving if damage to the
tire, such as cracks in the sidewall, appears.
A WARNING
Improper use of run-flat t ires can cause
veh icle damage that can lead to loss of ve­
hicle control, a crash and serious pe rsonal
injury.
- Run-flat tires can only be used with spe­ cial rims.
- Run-flat tires must always be mon itored
with a properly programmed Tire
P re­
ssure Mon itor ing System.
- Always inspect a tire that has lost air to
make sure it is safe to drive with the tir e
in the run-flat mode.
- Never drive with run-flat tires that have
been damaged in a collision .
- Never drive with run-flat tires if heat
build-up causes the tire to give off
smoke .
- Never drive with run-flat tires if the vehi­
cle shakes or v ibrates severely.
- Never drive with a run-flat tire that de­
velops sidewall cracks or other damage
wh ile in use .
- If you switch between standard and run ­
flat tires, an authorized Audi dealer or qualified workshop must reprogram the
control module .
-
(D Note
Run-flat tires have specia l characteristics
and requirements, that are very different
from conventional tires. Run-flat tires re­
quire special rims for run-flat use and can­
not be used on conventional wheel rims.
(D Tips
- If you are not able to cont inue driving
with run-flat tires, please seek professio­
nal assistance.
- Please contact your authorized Audi
dealer or Audi of America, Inc. if you
have questions about tires and rims .
Driving with run-flat tires
Applies to vehicles: wit h Run -flat tires
Handling characteristics change when tire
pressure is low .
Driving on tires with low tire pressure changes
the way a vehicle handles, particularly when
cornering and braking. The handling charac­
teristics of run-flat tires do not seem to
change a lot even when driving on low pres­
sure or in the run-flat mode . Nevertheless you
must still take specia l precautions when ope r­
at ing a vehicle on run-flat tires when tire pres­
sure is low o r the tire(s) is flat:
.,. The Electronic Stabilization Control (ESC)
must be switched on.
.,. Never drive faster than 50 mph (80 km/h)
¢&_ .
.,. Plan ahead when driving and anticipate
what you will have to do considering traffic
and road conditions up ahead .
.,. Accelerate carefully.
.,. Avo id unnecessary and sudden steering and
brak ing maneuvers.
.,. Reduce your speed in plenty of time before
intersections, curves and other places where
you may have to react quickly.
Please see :
¢ page 202, When it is not possi­
ble to continue driving, even with run-flat
tires?

Handling characteristics change when
driving with low air pressure or with flat
tires even with special run-flat tires
A low pressure or flat front tire affects vehicle
handling characteristics by pu lling the vehicle
slightly to the side where the tire is mounted
and reduces braking performance .
A low pressure or flat
rear tire also affects
driving character istics by pulling to the side
where the tire is mounted and also reduces
brak ing performance. The effect on vehicle
handling is most not iceable when driving
around curves.
A WARNING
Changed vehicle handling character istics
when driving in the run -f lat mode can
cause loss of vehicle contro l, a crash and
serious personal injury.
- Driving on special run-flat tires in the
run-f lat mode wi ll change vehicle han­
dling characteristics during braking,
when cornering and under heavy acceler­
ation.
- Never drive faster than the maximum
rated speed of 50 mph (80 km/h) when
dr iv ing in the run -flat mode.
- Always adjust vehicle speed to traffic,
road and weather cond itions and drive
slower than the max imum rated speed if
necessary weather and road conditions
are taken into account.
- Always obey speed limits and other traf­
fic laws.
Q) Note
We always recommend driving w ith even
more care when using these special t ires in
the run-flat mode . Always avo id sudden
maneuvers.
Tires and wheels 203
Replacing run-flat tires and rims
App lies to veh icles : w it h Run -flat t ires
Your vehicle was especially designed to use
special run-flat tires.
You may use and combine only approved run­
flat tires and special matching rims that have
been designed for run-flat tires. Mounting
special run-flat tires on standard wheels will not work and w ill not prov ide the advantages
fo the ru n-falt feature . Never use spec ial run­
flat tires on standa rd wheel rims.
After dr iving with a tire i n the run-flat mode,
always have the veh icle and affected tire(s)
and rim(s) inspected by a n authorized Audi
dealer. Tires that have been driven in the run­
f lat mode must be rep laced .
A WARNING
-Use of damaged run-flat tires and rims can
cause vehicle damage that can lead to loss
of vehicle control, a crash and serious per­
sonal injury.
- Always have the vehicle and affected
tire(s) and r im(s) inspected by an author­
ized Audi dealer after driving a tire in the
run-flat mode .
- Tires that have been dr iven in the run­
f lat mode must be replaced.
