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
installation 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 tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels 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 malfunction.
Using the ABS sensors, the tire pressure monitor-
ing system compares the tire tread circumfer-
ence and vibration characteristics of the individu-
al tires. If the pressure changes in one or more
tires, this is indicated in the Infotainment system
display with an indicator light
rD] and a message.
If only one tire is affected, the location of that
tire will be indicated.
The 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 replacing a tire on
your vehicle¢
page 271 . The tire pressure moni-
toring system only monitors the tire pressure you
have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢ page 262, fig.198.
Tire tread circumference and vibration character-
istics can change and cause a tire pressure warn-

- the tire pressure in one or more tires is too low.
- the tire has structural damage .
- the tire was replaced or the tire pressure was
changed and it was not stored ¢

- the spare tire* is installed.

ffim (Tire Pressure Monitoring System) Tire
pressure: malfunction! See owner's manual -
There is a system malfunction ifffimturns on af-
ter switching on the ignition or while driving and
the rD] indicator light flashes in the instrument
cluster for approximately one minute first and
then stays turned on . Try to store the correct tire
pressures
¢ page 271 . If the indicator light does
turn off or turns on again after a short period of
time, drive to an authorized Audi dealer or au-
thorized Audi Service Facility immediately to have
the malfunction corrected.
.&_ 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
tires and their pressure.
- The driver is responsible for maintaining the
correct tire pressures. You must check the
tire pressures regularly.
- Under certain conditions (such as a sporty
driving style, winter conditions or unpaved
roads), the pressure monitor 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 259 have been matched with
your Audi tire pressure monitoring system.
We recommend that you use these tires.
