2013 AUDI S8 ABS

268 Tires and wheels
and may affect the vehicle's handling and
stopping 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 vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction 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 ex ists.
When the malfunct ion indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­
ment or a lternate tires or whee ls 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 placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
App lies 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. 209 Display: underinflation warning
Fig. 210 Disp lay: System malfunction
Using the ABS sensors, the tire pressure moni ­
toring system compares the tire tread cir cum­
ference and vibration character istics of the in ­
dividua l tires. If the pressure decreases in one
o r more t ires, this is ind icated in the instru­
ment cluster with a warning symbol
[«E and a
message ~
fig. 209.
The tire pressure monitoring system must be
reset via MMI each t ime the press ures are ad­
justed (e.g. when switching between partial
and full load pressure) or after changing or re­
placing a tire on your vehicle
c::> page 269. 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::> page 2 53.
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
c::> page269.

Check the tire or tires and replace or repair if
necessary. The indicator light

ment cluster also illuminates

Check/correct the pressures of all four tires
and reset TPMS via MMI.

If llil~, appears after switching the ignition
on or whi le driving
¢ fig. 210 and the indica­
tor light
ltJ in the instrument cluster blinks
for approximate ly one minute and then stays
on, there is a system malfunction .
Attempt to store the correct tire pressure
¢
page 269. If the indicator light does not
turn off or if it turns on short ly thereafter, im­
mediately drive your vehicle to an authorized
Audi dealer or authorized repair facility to have the malfunction corrected .
A WARNING
-If the t ire pressure indicator appears in
the instrument cluster d isplay, one or
more of you r tires is s ignificantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures. In­
flate the tire pressure to the proper pres­
sure as indicated on the vehicle's tire pressure label ¢
page 253. 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.
- T he driver is responsible for ma inta ining
the corre ct tire pressures. You m ust
check the t ire pressures regularly .
- Under certain cond itions (such as a spor­
ty driving style, w inter condit ions or un­
paved roads) , the pressure monitor indi­
cator may be de layed .
- Ask your author ized Audi dealer if run ­
flat tires may be used on your vehicle.
Your vehicle regist rat ion becomes invalid
if you use these tires when not permit­
ted. Damage to your veh icle or acc idents
cou ld also resu lt.
(D Tips
- The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.

- T he tire pressure mon itor ing system on
your Audi was deve loped using tires with
the "AO" or "RO" identification on the
t ire s idewall

mend us ing these tires.
Reset tire pressure monitoring system
App lies to vehicles: wit h tire press ure mo nitor ing system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
MMI.

Do not store the tire pressure if there are
snow cha ins on the tire .
