258 Tires and wheels
It is important that the inflation pressu re is
regularly checked and maintained at recom­
mended levels .
Fo r more informat ion please ask your A udi
dealer for more details .
What you can do to avoid tire and rim
damage
L ow aspect ratio tires can be damaged more
easi ly by impact with potho les, curbs, gu llies
or ridges on the road, particularly if the tire is
underinflated.
I n o rder to minim ize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always maintain recommended inflation
pressures. Check 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 also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Audi dealer . Replace a damaged
t ir e as soon as possible.
- Inspect your tires 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 failure.
If you believe that a
t ir e may have been damaged, replace the
tire as soon as possible.
- T hese tires may wea r more quickly than oth­
ers.
- Please a lso remember that, while these tires
deliver respons ive handling, they may ride
less comfortably and make more noise than
other choices.
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance ti
res or iginally installed on your vehicle 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 drive under those circumstances, you
should equ ip your vehicle with all-season or
winter tires, which offer better traction unde r
those conditions. We suggest you use the rec­
ommended snow o r all-season tires specified
for your vehicle, or thei r equivalent.
Refer to~ page
255 for more detailed infor­
mation regarding winter tires.
Tire pressure
monitoring system
ill General notes
Each tire, including the spare (if provided),
shou ld be checked monthly when co ld and in­
flated to the inflat ion pressure recommended
by the vehicle man ufactur er on the veh icle
placard or tire inflation pressure labe l. (If your
vehicle has tires of a different size than the
size indicated on the vehicle placard or tire in ­
flation pressure label, you should determine
the proper t ire inflation pressure for those
t i res).
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
t ir es is signif icantly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you shou ld stop and check you r tires as
soon as possible, and inflate them to the
proper p ressure. 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 iciency and tire tread life,
and may affect the vehicle's handling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv­
er's responsibility 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 veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not operating properly . The
TPMS malfunction indicator is combined with
the low tire pressure tellta le . When the sys­
tem detects a malfunct ion, the telltale will
flash for approximately one minute and then
remain cont inuous ly illuminated. This se ­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is illuminat­
ed, the system may not be able to detect or
sig nal low t ire pressure as intended . TPMS
malfunct ions may occur for a variety of rea­
sons, including the installa tio n of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ion ing
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.
If the Tire Pressure Monitoring System
indicator appears
Applies to vehicles: with tire pressure monito ring system
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 . 177 In strum ent clus te r: indica tor l igh t w ith mes ­
sage
Using the ABS sensors, the tire pressure moni­
toring system compares the t ire tread circum­
ference and vibration characteristics of the in­
d iv idual tires . If the pressure changes in one

or more tires, this is indicated in the instru­
ment cluster disp lay with an indicator light
ti] and a message c:::> fig . 177. If only one tire
is affected, the locat ion of that tire will be in­
dicated. The message turns off after a few mi­
nutes . You can d isplay the message aga in
c:::> page 2 8 .
The tire pressures must be stored in the menu
display again each time the pressures change
(sw itching between partial and full load pres ­
sure) or after chang ing or replacing a t ire on
your vehicle
c:::> page 260 . The t ire press ure
monitori ng system only monito rs the tire
pressure yo u have stored . Yo u can find the rec ­
ommended t ire press ures for your vehicle on
the labe l on the driver 's doo r pillar

Tire t read circumference and vib rat ion charac­
teristics can change and cause a tire pressu re
warning if :
- I f the tire pressure in one or mo re tires is
t oo low,
- the t ire has structural damage,
-The tire was replaced or the t ire p ressure
changed and it was not stored again

-The spare tire is installed .
