instr ument cluster disp lay, reduce your
speed immediately and avoid any hard
steer ing o r braking maneuvers . Stop as soon
as poss ible and check the tires and the ir
p ressures.

tire p ressures regularly.
- Unde r ce rtain condit ions (such as a sporty
d riving s tyle, win ter condi tions or unpaved
roads), the pressu re moni tor indicator may
be de layed.
- Do not use run -flat tires on your vehicle. Us­

Tire pressure monitoring
system
(.L) 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 t ire 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
equ ipped w ith a t ire 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
p in g ability.
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 leve l
to trigger illuminat ion of the TPMS low tire pres­
sure telltale .
Your vehicle has also been equipped with a TPMS
malfunct ion 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
350
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 tel ltale after replac ing 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 monitoring system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the tema
perature and pressure in the tires. The data is
sent from these sensors to the control module by
radio frequency .
The tire pressure monitoring system shows the
current pressures and temperatures of the tires
in the Infotainment system while driving
¢ page 351. 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 351.
The system does not detect if the stored tire
pressures match the recommended tire pres ­
sures . You must store the tire pressures again
¢ page 352:
- 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.

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.
