2015 AUDI S8 tire pressure reset

264 Tires and wheels
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
malfunctions 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 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.
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. 213 Display : underi nflatio n warning
Fig. 214 Display: System mal functio 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, th is is indicated in the i nstru- ment
cluster with a warning symbol
[I] and a
message
r=> fig. 213 .
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad­
justed (e.g. when switching between partial
and full load pressure) or after changing or re­
plac ing a tire on your vehicle
r=> page 265. 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 dr iver's side B-pillar
r=> page 249.
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

-the spare tire* is mounted.
Warning symbols

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

ment cluster also illuminates

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

pressure! System malfunction.
Iflll appears
after switching the ignition on or while driving
¢fig . 214 and the indicator light [I] in the in­
strument cluster blinks for approximately one minute and then stays on, there is a system
malfunction . Attempt to store the correct tire
pressure ¢
page 265. If the indicator light
does not turn off or if it turns on shortly
thereafter , immediately drive your vehicle to

A WARNING ,~
- If the tire pressure indicator appears in
the instrument 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 249. Driving on a
signif icantly 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.
.
(0 Tips
- The tire pressure monitoring system may
stop working when there is an ESC mal­
function.
- 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 256. 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 storing the new tire pressures, check
that the current pressures on all four tires
correspond to the specified values and
Tires and wheels 265
adapt the pressures to the current load
¢page 249 .
.,. Switch on the ignition.
.,. Select in the MMI:
ICARI function button >
Car systems control button > Servicing &
checks > Tire pressure monitoring > Store
tire pressures > Yes, store now.
(D Tips
Do not store the tire pressure if there are
snow chains on the tire. Otherwise, a sys ­
tem malfunction may occur .
