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 whee ls on the veh i
cle that prevent the TPMS from funct io ni ng
p roperly . Always check the T PMS malfunct ion
tellta le afte r replacing one o r more t ires or
wheels on your veh icle to ensure that the re
p lacemen t 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.
Fig. 173 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 mo re tires, th is is indica ted in the instru
ment clus ter with a
RE wa rning symbol and a
message¢
fig. 173 . The driver message in the
disp lay goes out after 5 seconds . The driver
message can be displayed again by pressing
the
! SET ! button. If only one tire is affected,
the display will indicate its pos ition.
The ti re pressu re 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

tors the tire pressure that you have prev iously

stored . You can find the recommended t ire
pressures for yo ur vehicle on the label on driv

T ire tread circum ference and vibration charac
teristics can change and cause a tire pressure

- t he t ire has s tructural damage,
- the t ire pressure was changed, wheels rotat-
ed or replaced 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 significant ly under
inflated. Reduce your speed immediately
and avoid any hard steer ing or b raking
maneuvers. Stop as soon as possib le and
check the tires and their pressures. In
flate the tire pressure to the prope r pres
sure as indicated on the vehicle's tire
pressu re labe l
¢page 226. Driving on a
significantly under-inflated tire causes

24 2 T ire s and wheel s
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, winter 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.
Your vehicle registrat ion becomes invalid
if you use these tires when not permit
ted. Damage to your veh icle or acc idents
cou ld also resu lt.
@ Tips
- The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may resul t in a system
malfunction.
- The tire pressure monitoring system on
you r Audi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall¢
page 233 . 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*.
11> Before resett ing the TPMS, the cu rrent pres
sures of all fou r tires m ust correspond to
the specified val ues . Adjust the tire pressure
and reset the pressure i n the tire press ure
monitoring system according to the load
you are carry ing
