250 Tire s and wheel s
When the malfunction indicator is illuminat
ed, the system may not be able to detect or
signal low t ire pressure as intended. TPMS
malfunctions may occur for a variety of rea
sons, including the installation of replace
ment or a lternate tires or wheels on the vehi
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunct ion
tellta le afte r replacing one or more t ires or
wheels on your veh icle to ensure that the re
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies 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.

F ig. 181 Display : underinflatio n warning
Using the ABS sensors, the tire pressure moni
toring system compares the t ire tread circum
ference and vibration characteristics of the in
d iv idual tires . If the pressure decreases in one
or more tires, th is is indicated in the instru
ment cluster w ith a
IE warning symbol and a
message¢
fig. 181 . The driver message in the
display goes out after 5 seconds. The driver
message can be displayed again by pressing
the
! SE T! button. If on ly one tire is affected,
the display will indicate its pos it ion.
The tire pressure monitoring system must be reset via radio or MMI * each time the pres
sures are adjusted (e. g . when switching be
tween partia l and full load pressure) or after
changing or replacing a t ire on your vehicle
¢
page 251 . The TPMS indicator only moni
tors the tire pressure that you have prev iously stored
. You can find the recommended tire
pressures for yo ur vehicle on the label on driv
er's side B-pillar ¢
page 235.
Tire tread circumference and vibration charac
teristics can change and cause a tire pressure
warning if:
- the t ire p ress ure in one or more tires is too
low,
- the t ire has structural damage ,
- the t ire pressure was changed, wheels rotat-
ed or rep laced but the TPMS was not reset

A WARNING
=
-If the tire pressure indicator appears in
the instrument cluster display, one or
more of your t ires is sign ificant ly under
inflated. Reduce your speed immediately
and avoid any hard steer ing or braking
maneuvers. Stop as soon as possib le and
check the tires and their pressures. In
flate the tire pressu re to the prope r pres
sure as indicated on the vehicle's tire
pressu re labe l¢
page 235. D riving 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 ma inta ining
the correct tire pressures. You must
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 ind i
cator may be de layed .
-Ask your author ized Audi dealer if run
flat tires may be used on your veh icle .
You r vehicle registrat ion becomes invalid
if you use these tires when not permit
ted. Dam age to your veh icle or a cc iden ts
cou ld also resu lt.
@ Tips
- The t ire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- The t ire pressure monitoring system on
you r Audi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall¢
page 242. We recom
mend using these t ires .
Reset tire pressure monitoring system
Applies to vehicles: with tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro
tated or changed, the TPMS must be reset via
radio or MMI* .
.,. Before resetting the TPMS, the current p res
s u res of all four tires must correspond to
the specified val ues . Adjust the tire pressure
and reset the pressure in the tire press ure
monitoring system according to the load
you are carry ing
