2011 AUDI S8 TPMS

256 Tires and wheels
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 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
tires or have them inspected by the nearest
authorized Audi dealer. Replace a damaged
tire 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 tire failure . If you be lieve that a
t ir e may have been damaged, replace the
t ir e as soon as possible.
- T hese tires may wear mo re quick ly than oth­
ers.
- Please also remember that, while these t ires
deliver respons ive handling, they may ride
less comfortably and make more no ise 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 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 all-season tires specified
for your vehicle, or their equivalent. Refer
to
q page 253 for more detailed infor­
mation regarding winter tires.
Tire pressure monitoring system
(D General notes
Applies to veh icles: w ith tire pressure monitoring system
Each tire, including 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 vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the
s ize indicated on the vehicle placard or tire in­
flation pressure label, you should dete rmine
the proper tire inflation p ressure fo r those
t i res).
As an added safety feature, your veh icle has
been equipped with a tire pressure mon itoring
system (TPMS) that illuminates a low tire
pressure tel ltale when one or more of your
tires is significant ly under-inflated. According­
ly, when the low tire pressure telltale 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 failure . Under-inflation al ­
so reduces fuel efficiency 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 ma intenance, 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 illuminat ion of the
TPMS low tire pressu re tellta le .
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
T PMS ma lfunction indicator is combined with
the low tire pressure telltale. When the sys­
tem 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 exists.
When the malfunction 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 ment or alternate 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 t ires or
wheels on your vehicle to ensure that the re­
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring 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. 189 Display : underinflatio n warning
Fig. 190 Display: System malfu nctio 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, this is indicated in the instru-
Tires and wheels 257
ment cluster with a warning symbol [I) and a
message
r::!) fig. 189.
The tire pressure monitoring system must be
reset via MMI each t ime the pressures are ad ­
justed (e.g. when switching between partial
and full load pressure) or after changing or re­
placing a tire on your vehicle
r::!) page 258. You
can find the recommended tire pressures for
your vehicle on the label on driver's side 8-pil­
lar
r::!) page 242 .
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 tir e pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset

ment cluster also illuminates

on or while driving co
fig. 190 and the indica­
tor light
[I) in the instrument cluster blinks
for approximately one minute and then stays
on, there is a system malfunction . See your
authorized Audi dea ler as soon as possible .
A WARNING
-If the tire pressure indicator appears in
the instrument cluster display , one or
more of your tires is significant ly 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 .,.

258 Tires and wheels
pressure label~ page 242 . 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 cond itions (such as a spor­
ty driving style, winter condit ions or un­
paved roads), the pressure monitor indi­
cator may be delayed.
- Ask your author ized Audi dealer if run­
flat tires may be used on your veh icle.
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your vehicle or accidents
cou ld also result.
(D Tips
- The tire pressure monitoring system
stops working when there is an ESP/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- To ensure a proper TPMS function use
AUDI Original Tires which are marked
with "AO" or "RO" on the tire sidewall.
~p age 249.
- The tire pressure monitoring system on
your Audi was syntonized using tires with
the "AO" or "RO" identification. We rec­
ommend using these tires.
Reset tire pressure monitoring system
App lies to vehicles: with tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
MMI .
.. Switch on the ignition .
.. Se lect in the MMI: !CAR !function button>
Car systems contro l button > Servicing &
checks > Tire pressure monitoring > Store
tire pressures > Yes, store now.
(D Tips
Before resetting the TPMS, the current
pressures of all four tires must correspond
to the specif ied values. Adjust the tire
pressure and reset the pressure in the tire
pressure monitoring system according to
the load you are carrying~ page 242.
- Do not store the tire pressures if you are
dr iving with snow chains. Otherwise, a
system malfunction may occur.
