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, th is is ind icated in the instrument cluster
display with an indicato r light

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 224. 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 215, fig . 190.
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if :
- 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

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 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 pressure. You must check the
tire pressure regularly.
- Under certain conditions (such as a sporty
driving style, winter conditions or unpaved
roads), the tire pressure monitoring system
indicator may be delayed.
(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 tire pressure monitoring system in your
Audi was calibrated with "Audi Original
Tires"
¢ page 212. Using these tires is rec­
ommended .

of all four tires meet the specified values and
are adapted to the load

are installed.
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 tire inflation pressure 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
(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 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.

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
¢page 226. It also
compares the current tire pressures with the
stored tire pressures and gives a warning in the
driver information system if the tire pressure is
different from what is
stored ¢ page 226 .
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 226:
- 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

tem measures the current tire pressures and stores them as the new specified pressures.
~ If the changed tire pressures are not displayed
in the Infotainment system, drive the vehicle
for approximately 10 minutes so that the sen­
sor signal from the wheels is received again.
During this adaptation phase, --.·· is displayed
for the pressure and temperature and the tire
pressure monitoring system is only partially
available. It only provides a warning if one or
more tir e pressures is below the minimum per­
mitted specified pressure. If this is the case, the

Malfunctions
Applies to: vehicles with tire pressure monitoring syste m
-
If the Tire Pressure Monitoring System is not
avai lable, the
mm indicator light appears in the
driver information system. The
IE indicator light
also blinks for approximately one minutes each
time the ignition is switched on . The tire pressure
monitoring system cannot be selected in the In­
fotainment system. The fol lowing are examples
of situat ions that could cause a malfunction:
-If the message appears at the end of the adap­
tation phase, the system cannot detect the
wheels installed on the vehicle. This may resu lt
from one or more wheels being installed with­
out wheel sensors or with incompatible wheel
sensors.
-A wheel sensor or another component has
failed.
-Using snow cha ins can affect the function of
the system because of the shield ing effect of
the chains .
-The tire pressure monitoring system is not
available due to a malfunction.
-T ransmitters with the same frequency, such as
headphones or remote-control led dev ices, may
cause a temporary system malfunction due to
the strong electromagnetic field.
Wheels
T he m;i indicator light turns off once the Tire
Pressure Monitoring System is available again. If
you cannot correct the ma lfunction and the
m;i
indicator light stays on, drive immediately to an
authorized Audi dealer or authorized Audi Service
Facility to have the malfunction repaired.
