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
Appl ies to vehicles: with tire pressure monitoring sys te m
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. 188 Display: underinflation warning
Fig. 189 Display: System malfu nction
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- ment
cluster with a warning symbol
[I] and a
message
r=> fig. 188.
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 255. You
can find the recommended tire pressures for
your vehicle on the Label on driver's side 8-pil­ lar
¢ page 239.
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
r=> page 255.
Warning symbols
[I] Loss of pressu re in at least one tir e ¢ ,&. .
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.

If IIQIS, appears after switching the ignition
on or while driving¢
fig. 189 and the indica­
tor light
[I] in the instrument cluster blinks
f or approximately one minute and then stays
on, there is a system malfunction . See your
authorized Audi dealer 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 you r 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 .,..
