if
mm appears after switching on the ignition or
while driving and then the
[DJ indicator light in
the instrument cluster also starts to blink for
about one minute and then stays on permanen t­
ly, there is a system malfunction. Try to store the
correct tire pressures

tor light does turn off or turns on again after a
short period of time, drive to an authorized Audi
dealer or authorized Aud i Serv ice Facility immedi­
ately 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"
¢page 251 have been matched with your
Audi tire pressure monitoring system . Using
these tires is recommended.

it must be confirmed in the Infotainment sys­

Tire pressure monitoring
system
ill General notes
Each tire, including 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 vehicle has
tires of a different size than the size indicated on
the vehicle placard or tir e inflation pr essure la­
bel, you should 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
( T PMS) that illuminates a low tire pressure tell­
tale when one or more of you r 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
cant ly under-inflated t ire causes the tire to over­
heat and can lead to tire failur e. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping ability.
..,.

Cl 00 .-< N r-­N .-< 0 r-­Vl 00
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale .
Your vehicle has also been equipped 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 continue upon
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.
Description
Applies to: vehicles with tire pressure monitor ing system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
T he system uses sensors that measure the tem ­
perature and pressure in the tires . The data is
sent from these sensors to the control module by radio frequency.
T he tire pressure monitoring system shows the
current pressures and temperatures of the tires
in the Infotainment system while driving
¢ page 264. It also compares the current tire
pressures with the stored tire pressures and
gives a warning if the tire pressure is different
from what is stored
¢ page 264 .
Wheels
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must store the tire pressures again
¢ page 264:
- every time the tire pressures change, for exam­
ple when the load in the vehicle changes,
- after replacing a tire, or
- if wheels with new wheel sensors are used.
_& WARNING
- The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is extremely high.
This could result in serious damage to the
tire and even cause the tire to burst, in­
creasing the risk of an accident.
- A tire with low pressure flexes more. This heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci­
dent.
- The tire pressure monitoring system does not warn about damage or defects in the
tire construction that could cause the tire to
burst, for example. Inspect your tires regu­
larly.
(D Tips
- If tires are replaced, the sensors/valves do
not need to be removed or replaced . Just re­
placed the valve stem and, if necessary, the
valve and the wheel electronics. If you have questions, see an authorized Audi dealer or
authorized Audi Service Facility.
- An incorrect display or a malfunction in the
tire pressure monitoring system can occur
after using the tire mobility kit. Have the
sensors replaced by an authorized Audi
dealer or authori zed Audi Service Facility.
- For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see

Storing new tire pressures
Applies to: vehicles with tire pressure monitoring system
Correctly stored tire pressure specifications are
necessary for reliable tire pressure monitoring.
-
It is always necessary to store the t ire pressures
whe n the t ire pressu res a re modified, fo r exam­
ple d ue to a change in load . o r when new senso rs
a re installed.
"' Before storing the t ire pressures, make su re the
tire pressures of all four t ires meet the spec i­
fied va lues and are adapted to t he load
c::> page 254, fig. 190 . Only correct and store
the pressure in tires whose temperature is ap ­
proximate ly the same as the ambient tempera ­
t u re . If the temperature of the tire is higher
than the ambient air temperature, the tire pressure must be increased approximately
3.0 PSI (0.2 bar) above the value on the st icker.
