Tire Pressure Monitoring
System (AS, S8)
(D General notes
A ppl ies to: AS, 58
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat
ed to the inflation pressure recommended by the
veh icle manufact urer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la
be l, you should determine the proper tire infla
tion pressure for those tires).
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure te ll
tale when one or more of your tires is significant
ly under-inflated . Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi
cantly under-inflated tire causes the tire to over
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop
ping ability .
Please note that the TPMS is not a substitute for
p roper tire maintenance, and it is the driver's re
sponsib ility to ma intain correc t tire p ressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres
sure telltale.
Your veh icle has also bee n eq uipp ed w ith a TPM S
mal function indicator to indicate when the sys
tem is not operat ing properly. The TPMS mal
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi
mately one mi nute and then remain cont inuously
illuminated . This sequence will continue upon
Wheels
subsequent vehicle start-ups as long as the mal
function exists .
When the malfunction indicator is illuminated ,
the sys tem may not be able to detect or signal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
i nsta llation of replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the replacement or a lternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears
Applies to: A8, 58
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 monitor
ing system compares the tire tread c ircumfer
ence and vibration characteristics of the individu
al tires.
If the press ure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
[I] and a message.
If only one tire is affected, the location of that
tire will be indicated.
T he tire press ures must be stored in the Infotain
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle

- the tire pressure in one or more tires is too low.
- the tire has structural damage .

pressure: System malfunction!.
Ifmm appears
after switching the ignition on or while driving
and the
IE indicator light in the instrument clus
ter blinks for approximately one minute and then
stays on , there is system malfunction . Try to
store the correct tire pressures¢
page 302. If
the indicator light does turn off or turns on again
after a short period of time, drive to an author
ized Audi dealer or authorized Audi Service Facili
ty immediately to have the malfunction correct
ed .
A WARNING
- If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steer ing or braking maneu
vers . Stop as soon as possible and check the
t ir es and their pressure .
- The driver is responsible for maintaining the
correct tire pressure. You must check the
t ire pressure regularly.
- Under certain conditions (such as a sporty
dr iv ing style, winter cond itions or unpaved
roads), the tire pressure monitoring system
indicator may be delayed.
- Do not use run-flat tires on your vehicle. Us
ing them when not permitted can lead to
vehicle damage or accidents .

(D Tips
-The tire pressure monitoring system can al
so stop working when there is an ESC mal
function.
- Using snow chains may result in a system
malfunction.
- The tires with the identification "AO" or
"RO" ¢
page 290 have been matched with
your Audi tire pressure monitoring system.
We recommend that you use these tires.
Storing tire pressures
App lies to: AB, 58
If the tire pressure changes or a tire is replaced ,
it must be confirmed in the Infotainment sys
tem.
... Make sure before storing that the tire pressur es
of all four tires meet the specified values and
are adapted to the load ¢
page 291.
... Switch the ignition on.
... Select: the
ICARI funct ion button> Car Systems
control button > Servicing & checks > Tire
pressure monitoring
> Store tire pressure >
Yes, store now.
(D Tips
Do not store the tire pressures if snow chains
are installed. Othe rw ise the system could
malfunction.
