When it i s not po ssibl e to co ntinu e
d riv ing, even with run-fl at ti res?
-If the E lectronic Stabilization Control (ESC)
is not working or keeps coming on.
- If the Tire P ressure 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 dr iving if severe vibration
occurs or if the tire starts to smoke because
the tire is runn ing 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
vehicle damage that can lead to loss of ve­
hicle control, a crash and serious personal
injury.
- Run-flat tires can only be used with spe­
c ial rims.
- Run-flat tires must always be mon itored
with a properly programmed Tire Pre­
ss ure Mon itor ing System.
- Always inspect a tire that has lost air to
make su re it is safe to drive w ith the t ire
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 t ire 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 author ized Audi dealer or
qualified wo rkshop must reprogram the
control module.

@ Note
Run-f lat ti res have special characteristics
and requirements, that are very different
from convent ional tires. Run-flat tires re­
quire special rims for run-flat use and can­
not be used on conventional whee l rims .
(D Tips
- If you are not able to cont inue driving
w ith run-flat tires, please seek professio­
nal ass istance.
- Please contact your authorized Audi
dealer or Aud i of America, Inc . if you
have questions about t ires and rims.
Driving with run-flat tires
Applies to veh icles: w it h Run -flat t ires
Handling characteristics change when tire
pressure is low.
Driving on tires with low tire pressure changes
the way a veh icle handles, particularly when
corner ing 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 whe n oper ­
at ing a veh icle on run-flat tires when t ire pres­
s u re is low o r the tire(s) is flat:
" The Electronic Stabilization Contro l (E SC)
must be switched on.
" Never drive fas ter than 50 mph (80 km/h)
q .&_ .
"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
braking maneuvers.
" Reduce your speed in plenty of t ime before
intersections, curves and other places where
you may have to react quickly .

204 Tires and wheels
Handling characteristics change when
dr iving 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 pulling 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 characteristics by pul ling 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.
& WARNING
Changed vehicle handling characteristics
when driving in the run -flat mode can
cause loss of vehicle contro l, a c rash and
serious personal in jury.
- Driving on special run-flat tires in the
run-flat mode will 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.
(D Note
We a lways recommend driving w ith even
more care when using these specia l tires in
the run-flat mode. Always avo id sudden
maneuvers.
Replacing run-flat tires and rims
Applies to veh icles: w it h Run -flat tires
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 whee ls will
not work and will not provide the advantages
fo the run-falt feature. Never use special run­
flat tires on standa rd whee l rims.
After dr iving w ith a t ire in the run-flat mode,
always have the veh icle and affected tire(s)
and rim(s) inspected by an author ized Audi
dealer. Tires that have been dr iven in the run­
flat mode must be rep laced .
& 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.
- Tir es that have been dr iven in the run­
flat mode must be replaced.

A WARNING
If tire pressure is less than 1.3 bar after
driving for 10 minutes, the tire is too se­
vere ly damaged . Do not continue to drive .
Seek p rofessional assistance.
@ Tips
After a tire repair, have the sealant bottle
rep laced at a dealership . This restores full
functionality to the Tire Mob ility System .

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed the
right direction.
A un idirectional tire can be identified by ar­
rows on the sid ewall ,
which point in the direc­
tion of the rota tion. Yo u m ust follow the
specified direction of rota tion. This is ne ces sa ­
r y in order fo r these tires to develop t heir op ­
timum character istics regard ing grip, road
noise, wear, and hydrop laning.
