A 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 authorized Audi Service Facility.
- For an explanation on conformity with the
FCC regulations in the United States and the
Industry Canada regulations, see
r=;,page 386.
Displaying tire pressures/temperatures
Applies to: vehicles with tire pressure mo nito ring system
Requirement: you must be driving the vehicle.

tire pressures.
Wheels
The current tire pressures are shown in green,
yellow or red numbers in the Infotainment sys­
tem:
- Green: the current tire pressure and the speci­
fied tire pressure are approximately the same.
- Yellow: the current tire pressure is too low
compared to the specified tire pressure.
-Red: the current tire pressure is extremely low
compared to the specified tire pressure .
The specified tire pressure is the last tire pres­
sure that was stored
r=;, page 352.
Note that the tire pressure also depends on the
temperature of the tire. The tire pressure in ­
creases as the engine becomes warmer while
driving.
A WARNING
Read and follow the important information
and notes
"*page 350.
(D Tips
The tire pressure or temperature is not dis­
played while the vehicle is stationary and in
adaptation mode. Dashes--.-- are shown in
place of the pressure and temperature.

Wheels
~ Adapt your driving style to the situation.
~ Stop as soon as possible and check the tire(s) .
~ If it is possible to continue driving, see an au-
thorized Audi dea ler or authorized Audi Service
Facility immediately and have your tire(s) re­
paired or replaced.
A WARNING
Read and follow the important information
and
notes ~ page 350.
Storing new tire pressures
App lies to: ve hicles w ith tire press ure m on itoring system
Correctly stored tire pressure specifications are
necessary for reliable tire pressure monitoring.
-
It is always necessary to store the tire pressures
when the tire pressures are modified, for exam­ ple due to a change in load. or when new sensors
are installed .
~ Before storing the tire pressures, make sure the
tire pressures of all four tires meet the speci­
fied values and are adapted to the load
~ page 341, fig . 2 78 . Only correct and store
the pressure in tires whose temperature is ap­
prox imat ely the same as the ambient tempera­
ture .
If the temperature of the tire is higher
than the ambient air temperature, the tire
pressure must be increased approximate ly
3 .0 PSI (0 .2 bar) above the va lue on the sticker .
~ Switch the ignition on.
~ Select in the Infotainment system: IMENUI but­
ton
> Vehicle > left control button > Service &
checks > Tire pressure monitoring > Store tire
pressure > Yes, store now .
After storing the
tire pressu res, the t ire pressu re monitoring sys­
tem measures the current pressures wh ile driv­
in g and stores them as the new specified pres­
sures.
~ If the changed tire pressures are not displayed
in the Infotainment system, drive the vehicle
for approximate ly 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 mon itor ing system is only partially
ava ilable. It only provides a warning if one or
352 more
tire pressures is below the minimum per­
mitted specified pressure.
If the
[I] ind icator light turns on and the mes­
sage
Tire pressure : wheel change detected .
Please check all tires and store pressures in
MMI also appears, the system has detected that
the position of the sensors has changed because
of a tire rotation, or that new sensors were in­
stalled. Store the new tire pressures.
A WARNING
Read and follow the important information
and notes
~pag e 350.
Malfunctions
Applies to: vehicles with t ire pressure mo nitori ng syste m
If the tire pressure monitoring system is not
available, t he
mm in dicator light appears in the
instr umen t cluste r display along with the mes­
sage
Tire pressure : malfun ction! See owner's
manual.
-
If the ffim ind icator light appears after switch­
in g the ignitio n on or wh ile dr iving and the
[IJ in­
dicator light also blinks for approximately one
minute and then stays on, there is a system ma l­
function . The fo llowing are examples of situa­
tions that could cause a malfunction:
- If the message appears at the end of the adap ­
tation phase, the system may not detect one or
several of the whee l sensors necessary for pres­
sure monitoring. This may res ult from one or
more whee ls being installed without wheel sen­
sors or with incompatible wheel sensors.
- A wheel sensor or another component has
fa iled.
- Using snow chains can affect the function of
the system because of the shielding effect of
the chains.
- The tire pressure monitoring system is not
avai lab le due to a ma lfunction.
- Transmitters with the same frequency, such as
headphones or remote-controlled devices, may
cause a temporary system malfunct ion due to
the strong electromagnetic field.
