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

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 .,..
pressure label¢ page 239. 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 conditions (such as a spor ty driving style, winter conditions or unpaved roads), the pressure monitor indi
cator may be delayed.
-Ask your authorized Audi dealer if run
flat tires may be used on your vehicle.
Your vehicle registration becomes invalid if you use these tires when not permit
ted. Damage to your vehicle or accidents
could also result.
@ Tips
- The tire pressure monitoring system
stops working when there is an ESC/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.
¢page 246.
- 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 syste m
If the tire pressure is adjusted , wheels are ro
tated or changed, the TPMS must be reset via
MMI.
~ Switch on the ignition.
~ Select in the MMI: !CAR !function button>
Car systems control 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 specified values. Adjust the tire
pressure and reset the pressure in the tire
pressure monitoring system according to
the load you are carrying ¢
page 239.
-Do not store the tire pressures if you are
driving with snow chains. Otherwise, a
system malfunction may occur .
