through or over such obstacles can damage
your tires. Impact with a curb may also
cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Audi dealer. Rep lace 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 t ire failu re. If you bel ieve that a
t ire may have been damaged, replace the
t ire as soon as possible.
- These tires may wear more quickly than oth­
ers.
- Please also remember that, while these t ires
deliver respons ive handling, they may ride
less comfortably and make mo re no ise than
othe r cho ices .
Reduced performance in winter /co ld
season condition s
All tires are des igned for certain pu rposes.
The low aspect ratio, ultra high pe rformance
tires orig inally 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 conditions. If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, which offer better traction under
those cond it ions. We suggest you use the rec­
ommended snow or a ll-season tires specified
for your vehi cle, or their equ ivalent.
Refer to¢
page 267 for more deta iled infor­
mat ion regarding winter tires.
Tire pressure
monitoring system
U) General notes
Each t ire, includ ing the spare (if provided),
should be checked monthly when cold and in­
flated to the inflation pressure recommended by the vehicle manufacture r on the vehicle
p lacard or tire inflation pressure label. (If your vehicle has tires of a diffe
rent size than the
size indicated on the vehicle placard or tire in­
flat ion pressure labe l, you shou ld determ ine
the proper t ire inflation pressure for those
t ires).
As an added safety feature, your ve hicle has
been equipped with a tire pressure monitoring
system (TPMS) that illum inates a low tire
pressure telltale when one or more of your
t ires is significantly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you shou ld stop and check you r tires as
soon as possib le, and inflate them to the
proper p ressu re. Driving on a sig nifican tly u n­
der- inflated t ire causes the tire to overheat
and can lead to tire fai lure . Under-inflation al­
so reduces fuel efficiency 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 maintenance, and it is the driv­ er's respons ibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale .
Your vehicle has also been equipped with a
TPMS malfunction indicator to ind icate when
the system is not operating properly. The
TPMS ma lfunction indicator is combined w ith
the low tire pressure telltale . When the sys­
tem detects a malfunction, the telltale will
flash fo r approxima te ly one m inute and then
rema in continuously illum ina ted. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indica to r is illum inat­
ed, the system m ay not be ab le to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a var iety of rea­
sons, incl uding the insta llation of replace­
ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
whee ls on you r vehicle to ensu re that the re­
placement o r alternate ti res and wheels a llow
the TPM S to cont inue to func tion p roperly.

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. 205 Display: underinflation warning
Fig. 206 Display: System malfunction
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, this is indicated in the instru­
ment cluster with a warning symbol
rD] and a
message
c:> fig . 205.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad­
justed (e.g. when switching between partial
and fu ll load pressure) or after changing or re­
placing a tire on your vehicle
c:> page272 . 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 driver's side 8-pillar
c:>page247.
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

¢
fig. 206 and the indicator light rD] 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
pressure
c:> page 272. If the indicator light
does not turn off or if it turns on shortly
thereafter, immediately drive your vehicle to
an authorized Audi dealer or authorized repair
facility to have the malfunction corrected.
_& 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 247 . 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 maintaining
the correct tire pressures. You must check the tire pressures regularly.

272 Tires and wheels -Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor
indicator may be delayed.
- Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle.
- 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
c:> page 260. 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
adapt the pressures to the current load <=>page 247.
• Switch on the ignition.
• Select in the MMI: !CAR !function button>
(Car)* systems control button > Servicing &
checks > Tire pressure monitoring > Store
tire pressures> Yes, store now.
Do not store the tire pressure if there are
snow chains on the tire. Otherwise, a sys­
tem malfunction may occur.
