254 Tires and wheels
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 funct ioning
properly . Always check the TPMS malfunction
telltale after replacing one or more t ires 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
Applies to vehicles: with tire p ressure mo nitoring syste 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.

Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
d ividual tires. If the pressure decreases in one
or more tires, th is is indicated in the instru­
ment cluster with a warning symbol
'9] and a
message
<=>fig . 183.
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
placing a tire on your vehicle <=>
page 255. You
can find the recommended tire pressures for
your vehicle on the label on driver' s side B-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
<=> page 255.

Check the tire or tires and replace or repa ir if
necessary. The indicator light

Check/correct the pressures of all four tires
and reset TPMS via MMI.

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 your speed immediately
and avoid any hard steer ing 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
