Tires and wheels -
----------------
•
& WARNING (continued)
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i] Tips
• Each tire should be checked monthly when the temperature of
the tires is about the same as ambient air temperature and set to the
recommended inflation pressure as specified on the tire pressure
label =>
page 238.
• The factory supplied spare wheel is equipped with a sensor for
the tire pressure monitoring system *. As long as the spare wheel is
not mounted, the tire pressure of this tire will not be monitored.
• The tire pressure monitoring system * helps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• When tires are replaced, the sensors and valves should not be
exchanged . The valve core, nut, valve sealing and seal washer
(replacement kit) needs to be replaced. If necessary, the valve and
the wheel electronics have to be replaced.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system*.
Otherwise the system will register a malfunction and a fault
message will be displayed. For more information, contact your Audi
dealer. •
Adjust the tire pressure and store the pressure in the tire pres­
sure monitoring system* to the load you are carrying.

Significant loss of air pressure }
The yellow symbol appears in the event of a significant
loss of air pressure.
Fig. 153 Display:
yellow symbol with message
If the I warning light in the instrument cluster comes on
and then the(•' symbol appears in the display ~ fig. 153,
pressure in at least one tire is too low.
- Stop driving as soon as possible without endangering
yourself and other drivers on the road.
Inspect all tires.
- Change the tire if necessary ~
page 268.
The, warning light in the instrument cluster comes on when the
tire is significantly underinflated .
In addition, the tire symbol
J appears in the display together with
the message Please check tire pressure=> fig. 153. .._

Applies to vehicles: with tire pressure mon itorin g system
Wheel change
If a wheel is changed, the wheels that were exchanged
have to be re-programmed .
- Turn on the ignition.
- Press the button~
page 256, fig. 154 for approximately 5
seconds. You will hear a beep and the symbol in the button flas hes three times.
Programming is necessary :
• after the tires have been rotated on the vehicle, or the spare tire
is used,
• if tires with new wheel sensors are used .
A ll pressure warning indicators in the display will be canceled. The
system malfunction error message wil l not disappear until the
vehicle is underway . With pressing the button~
page 256, fig. 154,
the re -programming of the new sensors and storing of ac tua l pres ­
sures starts. This learning phase can take up to 10 minutes driving
time .
During the learning process the tire pressure monitoring system* is
not avai lable. •
Applies to veh ic les: with tir e pressure monitoring system
Malfunctions •
A malfunction can have various causes.
F ig . 155 Display:
S yst e m m alfun ctio n
If the .J., warning light in the instrument cluster flashes for approxi­
mately one minute and then remains continuously illuminated and
additional ly the T ~~ fig. 155 symbol appears in the display, the
tire pressure mon itoring system* is not available. This can have
various causes.
• If the message appears at the end of the lear ning process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a wheel sensor were
insta lled.
• A wheel sensor or other component may have failed .
• During initialization the system has detected more than 4 wheels
on the vehicle, for example whi le driving next to another car with a
tire pressure monitoring system*.
• A whee l change was made but the button
~ page 256 , fig. 154
was not pressed.
• Audi replacement parts were not used.
• I f snow chains are being used, system function can be compro ­
mised due to the shielding properties of the chains .
• The tire pressu re monitoring system* may not be available
because of a radio malfunction .
Vehicle care I t •

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
• Transmitters with the same frequency , such as radio head­
phones in the vehic le or radio equipment, can cause a temporary
disruption of the system through excessive electromagnetic fields .
• Elimina te the interference if possible/if you can and then
proceed as follows : Turn off the engine for 20 minutes . T hen drive
another
1 0 min. If the warning light comes on aga in, you should
contact your authorized Audi dealer immediately to have the problem corrected .
• Do not use commercially avai lable tire sea lants. Otherwise, the
e lectrical componen ts of the tire pressure monitoring system* wil l
no longer work properly and the sensor for the tire pressure moni­
toring system * will have to be replaced by a qualified workshop .•
Run-flat tires
Ap plies to ve hic les : w it h R un -f la t tires
Introduction
Run-flat tires help keep you moving if a tire goes flat.
Re inforced sidewalls give the tires run -flat capability if t ire pressure
is lost .
We recommend that run -flat tires only be mounted on vehicles that
were origina lly equipped with these special tires at the factory and
have a Tire Pressure Monitoring System.
Run-flat tire s can be identified by the letter s "RSC" on the tire side ­
wa ll.
If you do change the tires on you r vehicle from normal to run -flat
tires , you must buy the special rims required for run -flat tires, and
the Tire Pressure Mon itoring System must be reprogrammed by an
authorized Audi dea ler or other qual ified workshop.
What do run -fl at tires do ?
These specia l tires have run-flat capabilities that help keep you
moving if a tire loses pressure and goes flat. Under favorab le condi -tions tires can be driven
a
t lea st 30 mile s (50 km ), but you must not
drive
fa ster than 50 mph (80 km/h )=> page 259, "Driving with run ­
flat tires".
The Tire Pressure Monitoring System constant ly checks the air pres ­
sure in the tires. If the run-flat system is active (shown in the center
display), you must inspect the affected t ire or t ires and then decide
whether to cont inue dr iving. Be sure to fol low these tips
=> page 259, "Driving with run -flat tir es" .
When it is n ot po ssible to c ontinue dri ving, ev en with
run-flat tir es?
• I f the Electronic Stabi lization Program (ESP) is not work ing o r
keeps coming on.
• I f the Tire Pressure Monitoring System does not work.
• I f the tire has been severely damaged, in a crash, for example .
T he t read can separate from a damaged tire as the wheel turns , and
hit parts of the vehicle, such as the fuel tank filler neck, fuel lines or
brake lines.
• Do not con tin ue d riving if severe vibra tion occurs or if the tire
starts to smoke because the tire is running hot.
• Do not conti nue drivi ng if da mage to the tire, such as cracks in
the sidewal l, appears .
& WARNING
Improper use of run -fl at tires can cause ve hic le da mage th at can
le ad to los s of vehicle control , a crash and seriou s personal injury .
• Run-flat t ires can only be used w ith spe cial rims .
• Run -fl at tires must always be monitored with a properly
programmed Tire Pre ssure Monitoring Sy stem.
• Alway s inspect a tire that ha s lo st air to make sure it i s safe to
drive with the tire in the run -flat mode .
• Never dr ive with run -fl at tire s th at have been dam aged in a
colli sion.
