302 Tire s and whee ls
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.
F ig . 255 D isp lay: underinflation warn ing
Using the ABS sensors, the tire pressure moni
toring system compares the tire tread circum
ference and vibration characteristics of the in
d iv idual tires. If the pressure decreases in one
or more tires, this is indicated in the instru ment cluster with a
RE warning symbol and a
message ¢
fig. 255 . The dr iver message in the
d isplay goes out after 5 seconds . The dr iver
message can be displayed again by pressing
the
! CHECK I button. If only one tire is affect
ed, the display will indica te its pos ition.
The tire pressure monitoring must be reset via MMI each time the pressures are adjusted (e.
g. when switch ing between partial and full
l oad pressure) or after changing or replac ing a
tire on your vehicle¢
page 303. The TPMS in
dicator only monitors the tire pressure that
you have previously stored. You can find the
recommended tire pressures for your vehicle
on the label on dr iver's side 8-pillar
¢page 278.
Tire tread circumference and vibration charac
teristics can change and cause a tire pressure
warn ing if:
- the tire pressure in one or more tires is too
l ow,
- the tire has st ructural damage,
- the tire pressure was changed, whee ls rotat-
ed o r replaced but the TPMS was not reset
¢ page 303,
-the sp are tire* is mounted.
Warn ing symbo ls
RE Loss of pressure in at least one tire¢,&..
Check the tire or tires and rep lace or repa ir if
necessary . The
RE indicator light in the instru
ment cluster also illuminates
¢ page 14.
Check/correct the pressures of all four tires
and reset TPMS via MMI.

pre ssure: System m alfunction!. If [m'El ap
pears after switching the ignition on or while
driving and the
RE i ndicator light in the in
strument cluster bli nks for approx imately one
minute and then stays on, there is a system
malfunction . Attempt to store the correct tire
pressure
¢ page 303. If the indicator light
does not tu rn off or if it t urn s on sho rtly
thereafte r, immediately d rive yo ur vehicle to
an a uthorized Audi dea ler or a uthorized repair
facility to have the malfunction corrected.
A WARNING ......_
- If the tire pressure ind icator 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 b raking
maneuvers. Stop as soon as possib le and
check the tires and their pressu res. In
flate the ti re p ressu re to the proper pres
sure as indicated on the vehicle's tire
pressure labe l
r=:>page 278. Driving on a
sign ificantly under-inflated tire causes
the t ire to overheat and can lead to tire
fa ilure. Under-inflation also is likely to
impair the vehicle's handl ing and stop
p ing ability .
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regu larly.
- Under certain conditions (such as a spor
ty driv ing style, winter conditions or un
paved roads), the pressure monitor indi
cator may be delayed .
-Ask you r aut horized Aud i dea ler if run
flat t ires may be used on you r vehicle.

@ Tips
-The tire pressure m onitoring system may
stop working when there is an ESC mal
funct ion.
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
your A udi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall
c:> page 291. We recom
mend using these t ires.
Reset tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro
tated or changed, the TPMS must be reset via
MMI.
.. Before stor ing the new tire pressures, check
t h at the current pressures on all four t ires
correspond to the specified values and
adapt the p ress ures to the current load
