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 order to minimize the occurrence 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 air if neces­
sary.
- Drive carefully 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
t ires 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 you be lieve that a
tire may have been damaged, replace the
tire as soon as possible.
- These tires may wea r more quickly than oth­
ers.
- Please also remember that, while these tires
deliver responsive 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
tires originally installed on your veh icle are in ­
tended for max imum dry and wet road per­
formance and handling . They are not suitable
for cold, snowy or icy weather condit ions . If
Tires and wheels 2 91
you drive under those ci rcumstances, 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 288 for more detailed infor­
mation regarding 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 inflation pressure label. (If your
vehicle has tires of a d ifferent size than the
s iz e indicated o n the vehicle placard or tire in­
flat io n pressu re lab el, you sho uld determine
the p roper tire inflation pressure for those
tires).
As an added safe ty feature, your veh icle has
been equipped with a tire pressure monito ring
system ( TPMS) that illuminates a low ti re
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 efficien cy and tire tread life,
and may affect the vehicle's hand ling and
stopping ability .
Please note that the TPMS is not a subst itute
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 leve l to tr igger illumination of the
T PMS low tire pressure tellta le .
Your vehicle has also been eq uipped with a
T PMS ma lfunction indicator to indicate when
the system is not operating properly. The
ll-

292 Tires and wheels
TPMS malfunction indicato r is combined with
the low tire pressure telltale . When the sys­
tem detects a malfunct ion, the te lltale 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 exists.
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low t ire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, includ ing the installat ion of replace­
ment or alt ernate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunct ion
tellta le after replacing one or more tires or
wheels on your vehicle to ensure that the re­ p lacement or a lternate 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. 254 D isplay: underinflat ion wa rning
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 instr u­
ment cluster with a
[D] warning symbol and a
message ¢
fig. 254. The driver message in the
display goes out after S seconds. The driver
message can be displayed again by pressing
the
! CHECK I button . If only one tire is affect­
ed, the display will indicate its position . The tire pressure
monitoring must be reset via
MMI each time the pressures are adjusted (e.
g. when switching between partial and full
load pressure) or after changing or replacing a
tire on your vehicle¢
page 293. The TPMS in­
dicator on ly monitors the tire pressure that
you have prev iously stored . You can find the
re commended t ire pressures for your vehicle
on the label on driver's s ide B-pillar
¢page 277.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the t ire pressure in one or more tires is too
low,
- the t ire has structural damage,
- the t ire pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset

If ffiim appears afte r switching the ignition on
or whi le dr iving and the

the instrument cluster blinks for approx i­

Attempt to store the correct tire pressure
¢
page 293. If the indicator light does not
turn off or if it turns on shortly thereafter, im­
med iate ly drive your vehicle to a n author ized
Audi dealer or authorized repair facility to
have the malfunction corrected.
.&_ WARNING
- If the tire pressure indicato r appears in
th e ins trum ent 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 2 77. 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.
- 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.
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your vehicle or accidents could also result.
@ 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 284. 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 resetting the TPMS, the current pres ­
sures of all four tires must correspond to
the specified values. Adjust the tire pressure and reset the pressure in the tire pressure
