Tire pressure monitoring
system
CD General notes
Each tire, includ ing the spare (if provided),
should be checked monthly when cold and inflat
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your veh icle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la
be l, you shou ld determine the proper tire infla
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell
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 poss ible, 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 t ire 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
proper tire maintenance, and it is the driver's re
sponsib ility to ma inta in correct tire pressure,
even if under-inflation has not reached the level
to trigger illuminat ion of the TPMS low t ire pres
sure telltale.
Your vehicle has also been equ ipped with a TPMS
malfunction indicator to indicate when the sys
tem is not operating 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 minute and then remain continuously
illuminated . This sequence will cont inue upon
Wheels
subsequent vehicle start -ups as long as the mal
function exists.
When the malfunction indicator is illuminated ,
the system 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
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more t ires or wheels on your veh icle to ensure
that the replacement or alternate t ires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
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 mo/function .
Fig. 199 Instrument cluster: indicator light with message
Using the ABS sensors, the tire pressure monitor
ing system compares the tire tread circumference
and vibration characteristics of the individual
tires . If the pressure changes in one or more
t ir es, this is indicated in the instrument cluster
display with an indicator light
HE and a message.
If only one tire is affected, the location of that
tire will be indicated.
T he tire pressures 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 rep lacing a tire on
your vehicle

toring system only monitors the tire pressure you have stored. Refer to the tire pressure label for ..,.

the indicator light does turn off or turns on again
after a short period of time, drive to your 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 steering 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
tire pressure regularly.
- Under certain conditions (such as a sporty
dr iving style, winter cond itions or unpaved
roads), the tire pressure monitoring system
indicator may be delayed.
- Do not use run-flat tires on your veh icle. 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 240 have been matched with
your Audi tire pressure monitoring system.
We recommend that you use these tires.
Storing tire pressures
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 pressures
of all four tires meet the specified values and
are adapted to the load¢

(D Tips
Do not store the tire pressures if snow chains
are instal led.
