Wheels
The grade C corresponds to a leve l of perform ­
ance which all passenger car tires must meet un­
der the Federa l Motor Vehicle Safety Standard
No.
109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING -
The traction grade ass igned to this tire is
based on straight-ahead braking traction
tests, and does not include acce le rat ion, cor­
ne ring, hydroplaning or peak traction charac­
teristics.
A WARNING
Th e temperatu re grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separate ly or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
-
-
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Tire Pressure Monitoring System indicator
(J.) General notes
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
ve hicl e manufacturer on the vehicle placard or
tire in flat ion press ure label. ( If yo ur vehicle has
t ires of a different siz e than the size indicated on
the vehicle placard or tire inflation pressure la­
be l, you should determine the proper tire infla­
tion pressure for those t ires) .
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure te ll­
tale when one or more of your t ires is significant­
ly under-inflated. Accordingly, when the low tire
pressure tellta le illuminates, you should stop and
348
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 t ire to over­
heat and can lead to tire fa ilure . Under-inflation
also reduces fue l eff iciency and tire tread life,
and may affect the vehicle's handling and stop ­
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the dr iver's re­
spons ibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
su re te lltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating prope rly . The TPM S 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 wi ll continue upon
s ub sequent vehicle start-ups as long as the mal­
funct ion exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
l ow tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
i nstallation of replacement or alternate tires or
wheels on the veh icle that prevent the TPMS
from functioning properly. Always check the
TPMS ma lfunction telltale after replac ing one or
more tires or wheels on you r vehicle to ens ure
that the rep lacement or alternate tires and
whee ls allow the TPMS to continue to function
properly.

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

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

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

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.

u. 00 .-< N l'­ N .-< 0 N > 00
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.

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.

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
