2015 AUDI A8 ABS

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
¢ page 265,
-the spare tire* is mounted.
Warning symbols
[I] Loss of pressure in at least one tire¢&,. .
Check the tire or tires and replace or repa ir if
necessary . The indicator light
[I] in the instru­
ment cluster also illuminates
¢page 11.
Check/correct the pressures of all four tires
and reset TPMS via MMI.

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
