or ridges on the road, particularly if the tire is underinflated .
I n o rder to m inim ize the occu rrence of impact
damage to the t ires of your vehicle, we recom ­
mend that you observe the following precau­
tions :
- Always maintain recommended inflat ion
pressures. Chec k your tire pressure every
2,000 miles (3 ,000
km) and add air if neces­
sary.
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may a lso
cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer. Replace a damaged
t ire as soon as possible .
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of
air and underinflation, wh ich could eventu­
ally cause tire failure . If you be lieve that a
t ire may have been damaged , replace the
t ire as soon as possible.
- T hese tires may wea r mo re qui ckly than ot h­
ers.
- Please a lso remember that, whi le these tires
deliver respons ive handling, they may ride
l ess comfortably and make mo re noise than
othe r choices.
Reduced perf ormance in winter /cold
s eason condition s
All tires are des igned for certa in pu rposes.
The low aspect ratio, ultra high performance
tires originally installed on your veh icle are in­
tended for maximum dry and wet road per­
formance and handling . They are not suitable
for cold , snowy or icy weather condit ions .
If
you dr ive under those circums tances, you
should equip your vehicle with all -season or
winter tires, which offer better traction under
those cond itions . We suggest you use the rec­
ommended snow or all-season tires specified
for your ve hicle, or their equ ivalent.

mation regarding winter tires.
Tire pressure monitoring system
General notes
Applies to veh icles: w ith t ire pressure monitoring system
Each tire, incl uding the spare (i f provided),
shou ld be checked monthly when co ld and in­
flated to the inf lation pressure recommended
by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle ha s tires of a different size than the
s ize indicated on the vehicle placard or tire i n­
flat ion pressu re labe l, you shou ld dete rm ine
the p roper t ire inflation p ress ure fo r those
t i r es.)
As an added safety feature , your ve hicle has
been equipped with a tire pressure mon ito ring
system ( TPMS) that illum inates a low ti re
pressure te lltale when one or more of your
tires is significant ly under -inflated . Acco rding­
ly, when the low tire pressure te lltale i llumi­
nates, you should stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly un­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under -inflation al ­
so reduces fuel effic iency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's respons ibility to maintain co rrect tire
pressure, even if under-inflation has not
rea ched the level to tr igger illum inat ion of the
T PMS low tire pressure tellta le .
Your vehicle has also been equipped with a
T PMS ma lfunction indicator to ind icate when
the system is not operating prope rly . T he
T PMS ma lfunction indicator is combined with
the low tire pressure te lltale. When the sys­
tem detects a malfunction , the telltale wi ll
flash for approximate ly one minute and then ..,_
•
•

Inflate the tire pressure to the proper
pressure as indicated on the vehicle's tire
pressure label¢
page 185. Driving on a
significantly 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 stop­
ping ability.
- The driver is responsible for mainta ining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, wint er conditions or un­
paved roads), the pressure monitor indi­
cator may be delayed .
- Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle.
Your vehicle registration becomes invalid if you use these tires when not permit ­
ted. Damage to your vehicle or accidents
could also result.
- If you switch between standard and run­
flat tires, an authorized Audi dealer or
qualified workshop must reprogram the
control module .
@ Tips
-The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
your Audi was developed using tires with the "AO" or "RO" identification on the
tire sidewall¢
page 192. We recom­
mend using these tires.

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.
Tire s an d wheel s 203
@ 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.

Maintenance
General
Your vehicle has been designed to help keep
maintenance requirements to a minimum.
However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle's
s afety, economy and rel iability. For detailed
vehicle maintenance consult your Warranty &
Maintenance booklet.
Under difficult operating conditions, for ex­
ample at extremely low outside temperatures,
i n very dusty regions , etc., some service work
should be performed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air filter.
@ For the sake of the environment
By regu larly maintaining your vehicle, you
help make sure that emission standards
are maintained, thus minimizing adverse
effects on the environment .
' Important considerations for you and
your vehicle
T he increasing use of electron ics , soph isticat­
ed fuel injection and emission control sys­
tems, and the generally increasing technica l
complexity of today's automobiles, have
liJJ,

steadily reduced the scope of maintenance
and repairs which can be carried o ut by vehicle
owners.
Also, safe ty and en vironment al con­
cerns p lace very strict limits on the nature of
repairs and adjustments to engine and trans­
miss io n parts which an owner can perform .
Maintenance, adjustments and repa irs usua lly
require special tools, testing dev ices and oth­
er equipment availab le to specially trained
workshop personne l in order to assure proper
pe rformance, reliab ility and safety of the vehi­
cle and its many systems .
Improper ma intenance, adjustments and re­
pa irs can impair the operation and reliability
of your vehicle and even void your vehicle war­
ranty. Therefore, p roof of servic ing in accord­
ance w ith the maintenance schedule may be a
condition for upholding a poss ible war ran ty
claim made within the warranty period .
Above all, operational safety can be adversely
affected, creating unnecessary risks for you
and your passengers .
If in doubt about any serv icing, have it done
by your authorized Audi dealer or any othe r
p roperly equipped and q ualified works hop .
We strong ly urge you to give yo ur auth o rized
Aud i dea ler the opportuni ty to perform all
schedu led maintenance and necessary repairs .
Your dea ler has the facilities, original parts
and tra ined spec ialists to keep your vehicle
running properly.
