What you can do to avoid tire and rim
damage
L ow aspect ratio tires can be damaged more
eas ily by impact with potho les, curbs, gu llies
or ridges on the road, particularly if the tire is
underinflated.
I n order to minimize the occu rrence o f 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 a ir 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 t ires. Impact with a curb may also
cause damage to your tires.
- After any impact, immediately inspect your
tir es or have them inspected by the nearest
authorized Aud i dealer . Replace a damaged
t ir e 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 unde rinflation, wh ich could eventu­
ally cause tire failure. If yo u be lieve that a
tire may have been damaged, replace the
tire as soon as possible.
- T hese tires may wear more quickly than oth­
ers.
- Please also remember that, while these tir es
deliver responsive handling, they may ride
l ess 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
tires originally 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 condit ions . If you drive
under those circumstances, you
shou ld equip your vehicle with all-season or
winter tires , which offer better traction under
those conditions. We suggest you use the rec­ ommended snow or all-season t ires specified
for your vehicle, or their equivalent .
Refer to~
page 289 for more detailed infor­
mation regarding winter tires.
Tire pressure
monitoring system
General notes ill
Each tire, including the spare (if provided),
should be checked monthly when cold and in­
flated to the inflation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the
s iz e indicated on the vehicle placard or tire in­
flat ion press ure la bel, you should determine
the proper tire inflation pressure for those
ti res.)
As an added safety feature, your ve hicle has
been equipped with a tire pressure monitoring
system ( TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. According­
l y, when the low tire pressure te lltale illumi­
nates, you should stop and check your tires as
soon as possible, 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 efficiency and tire tread life,
and may affect the vehicle's hand ling and
stopping ability .
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the leve l to trigger illuminat ion of the
T PMS low tire pressure tellta le .
Your vehicle has also been equipped with a
T PMS ma lfunction indicator to indicate when
the system is not operating properly. The
ll>

TPMS malfunction indicator is combined with
the low tire pressure tellta le . When the sys·
tern detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This se·
quence will continue upon subsequent vehicle
start-ups as long as the malfunction ex ists .
When the malfunc tion indicator is illuminat·
ed, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunct ions may occur for a variety of rea·
sons, including the installation of replace·
mentor 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
wheels on your vehicle to ensure that the re­
p lacement 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.

or more tires, this is indicated in the instru­

display goes out after S seconds . The driver
message can be displayed again by pressing
the

ed, the disp lay wi ll indicate its posit ion.
The tire pressure monitoring must be reset via
MMI each time the pressures are adjusted (e.
g. when switching between part ial and fu ll
load pressu re) o r after changing or replacing a
tire on your vehicle
c;, page 294. You can find
the recommended tire pressures for your vehi ·
cle on the label on the driver's door pillar
c;,page 278.
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 tir e has structural damage ,
- the tir e pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset

,8. WARNING
-If the t ire pressure indicator appears in
the instrument cluster display, one or
more of your tires is s ignificantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or bra king
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
c> page 2 78. 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 ab ility.
- The driver is responsible for ma inta ining
the correct tire pressures. You must check the t ire pressures regularly.
- Under certain cond itions (such as a spor­
ty driving style, winter condit ions or un­
paved roads), the pressure mon itor ind i­
cator may be de layed.
- Ask your author ized Audi dealer if run­
flat tires may be used on your veh icle.
Your vehicle registrat ion becomes inval id
if you use these tires when not permit ­
ted. Damage to your vehicle or accidents
cou ld also resu lt.
(D 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
you r A udi was ca lib rated using tires with
the "AO" or "RO" identification. We rec­
ommend 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 .
