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 veh icle, 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 ir e may have been damaged, replace the
t ire as soon as possible.
- T hese tires may wea r mo re qui ck ly 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 performance in winter /cold
season 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 circumstances, you
should equip your veh icle with all-season or
winter t ires, which offer better traction under
those cond itions. We suggest you use the rec­
ommended snow or all-season tires specified
for your ve hicl e, or their equ iva lent.

mation regard ing winter tires.
Tire pressure
monitoring system
ill General notes
Each tire, incl uding the spare ( if provided),
shou ld be checked monthly when co ld and in­
flated to the inflation pressure recommended by the veh icle manufacturer on the veh icle
placard or tire inf lation pressure label. (If your
vehicle has tires of a different size than the s ize indicated on the vehicle placard or tire in­
flat io n pressure labe l, you shou ld determ ine
t h e p rope r tir e inflation p ressu re fo r those
ti res).
As an added safety feature, your veh icle has
been equipped with a tire pressure mon itoring
system ( TPMS) that illum inates a low t ire
pressure te lltale whe n one or more o f you r
tires is significant ly under-inflated . According­
ly, when the low tire pressure te lltale illumi­
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 tire causes the tire to overheat
and can lead to tire fa ilure. Under-inflation al ­
so reduces fuel eff ic 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
reached the leve l to tr igger illuminat ion of the
T PMS low tire pressu re tellta le .
Your vehicle has also been equipped with a
T PMS ma lfu nction ind icator to ind icate when
the sys tem is not operating properly. The
T PMS ma lfunction indicator is combined with
the low tire pressure te lltale. When the sys ­
tem detects a malfunction, the telltale will
flash for approximate ly one minute and then ..,.

remain continuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a variety of rea­
sons , including the installation of replace­
ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly . Always check the TPMS malfunction
tellta le after replacing one or more tires or
wheels on your veh icle to ensure that the re­
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig. 213 Display : underi nflatio n warning
Fig. 214 Display: System mal functio n
Using the ABS sensors , the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
dividual tires . If the pressure decreases in one
or more tires, th is is indicated in the i nstru- ment
cluster with a warning symbol
[I] and a
message
r=> fig. 213 .
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad­
justed (e.g. when switching between partial
and full load pressure) or after changing or re­
plac ing a tire on your vehicle
r=> page 265. The
TPMS indicator only monitors the tire pres­
sure that you have previously stored. You can
find the recommended tire pressures for your
vehicle on the Label on dr iver's side B-pillar
r=> page 249.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the tire pressure in one or more tires is too
low,
- the tire has structural damage,
- the tire pressure was changed, wheels rotat -
ed or replaced but the TPMS was not reset

after switching the ignition on or while driving
¢fig . 214 and the indicator light [I] in the in­
strument cluster blinks for approximately one minute and then stays on, there is a system
malfunction . Attempt to store the correct tire

does not turn off or if it turns on shortly
thereafter , immediately drive your vehicle to
an a utho rized Aud i dealer or authorized repair
facility to have the malfunction corrected.

A WARNING ,~
- If the tire pressure indicator appears in
the instrument cluster display, one or
more of your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire
pressure label¢
page 249. Driving on a
signif icantly 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 maintaining the correct tire pressures. You must check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter 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.
.
(0 Tips
- The tire pressure monitoring system may
stop working when there is an ESC mal­
function.
- 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 256. We recom­
mend using these tires.
Reset tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
MMI.
.,. Before storing the new tire pressures, check
that the current pressures on all four tires
correspond to the specified values and
Tires and wheels 265
adapt the pressures to the current load
¢page 249 .
.,. Switch on the ignition.
.,. Select in the MMI:
ICARI function button >
Car systems control button > Servicing &
checks > Tire pressure monitoring > Store
tire pressures > Yes, store now.
(D Tips
Do not store the tire pressure if there are
snow chains on the tire. Otherwise, a sys ­
tem malfunction may occur .
