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 function ing
properly . Always check the TPMS malfunction
tellta le after replacing one or more tires or
wheels on your vehicle to ensure that the re
placement or alternate 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.

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 , th is is indicated in the instru
ment cluster with a warning symbol

find the recommended tire pressures for your
vehicle on the label on dr iver's side B-pillar

A WARNING
-If the tire pressure ind icator appears in
the instrument cluster display, one or
more of your tires is significantly under
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possib le and .,.
26 6 T ire s and whee ls
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
c> page 250. 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.
- T he driver is responsible for ma inta ining
the correct tire pressures. You must check the t ire pressures regular ly .
- Under certain cond itions (such as a spor
ty driving style, winter condit ions or un
paved roads), the pressure monitor indi
cator may be de layed .
- Ask your author ized Audi dealer if r un
flat tires may be used on your vehicle .
Your vehicle regist ration becomes invalid
if yo u use these tires when not permit
ted. Damage to your veh icle or accidents
cou ld also result.
- The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction .
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
your Audi was developed using tires with
the "AO" or "RO" identif ication on the
tire sidewall
c> page 257. We recom
mend using these t ires.
Reset tire pressure monitoring system
App lies to vehicles: with tire pressure monito ring system
If the tire pressure is adjusted, wheels are ro
tated or changed, the TPMS must be reset via
