Tires and wheels Ill
----------------
sure label lists the recommended cold tire inflation pressures for the
vehicle at its maximum capacity weight and tires that were on your
vehicle at the time it was manufactured.
If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupants), you can adjust tire pressures to
those specified for normal vehicle load. Before operating the
vehicle at maximum load, you must increase the tire pressures to
those specified for maximum vehicle load~& .
Bear in mind that the tire pressure monitoring system* can only
mon itor the tire pressures you have stored . The system does not
recognize the load condition of your vehicle.
Th e effectiveness of the tire pressure monitoring system* will be
impaired if you store normal load pressures but then operate the
vehicle at its maximum load~.&, . See the
illustration
~ page 310, fig. 2 52 for the locat ion of the label
either on dr iver's side B-pillar or inside the fuel filler flap (color of the
actual label and exact location on the vehicle will vary slightly) .
Note that the following tab le is accurate at the time of going to press
and is subject to change. In the event of discrepancies , the tire pres­
sure label (On USA vehicles, the tire pressure label is located on the
dr ive r's side B -pillar . On Canada veh icles, the tire pressure label is
located either on the dr iver's s ide B-pillar or inside the fue l f ill er flap)
always takes precedence.
The table below lists the recommended cold t ire inflation pressures
for the Audi model covered by your Owner's Literature at the vehicle's
capacity weight and the tire sizes insta lled on the respective models
as original equipment, or as a factory option .

• The tire pressure monitoring system helps the driver to keep an
eye on tire pressures. B ut the driver still has the responsibility for
maintaining the correct tire pressure .•
A pplie s to v ehi cle s: w ith Tire pre ssure moni toring syst em
Storing tire pressures
Correct storage of specified pressure is the basic require­
ment for reliable tire pressure monitoring.
In order for the tire pressure monitoring system to operate
appropriately, you have to re-save the specified pressures
whenever you adjust tire pressure, for example when the load
condition of your vehicle changes . Proceed as follows:
Corr ecting tir e pr essure
- Check the pressure in the tires (including the spare t ire*) .
- Adjust air pressure as needed in accordance with t he infor -
mation on the label located e ither on the driver's side B ­
pillar (visible when the door is open), inside the fuel filler
flap and additionally in the manual.
Saving tire p ressures
- Turn on the ignition.
- Press the [
CAR] function button .
- Select
Systems in the CAR menu .
- Select
Tire pressure mon itoring .
-Select Sto re curr. tire pressure s~ page 329, fig . 259 .
All pressure warning indicators in the display will be canceled.
Following each intentional change in specified pressures, tire pres­
sures must be resaved . After the
pressures are saved, the tire pressure monitoring system
measures the c urrent tire pressures and saves them as the new spec­
ified pressures .
(I] Tips
• The tire pressure is shown on the tire pressure label. On USA vehi­
cles, the tire pressure label is located on the driver's side B-pillar. On
Canada veh icles, the tire pressure label is located either on the
driver's side B-pillar or inside the fuel filler flap . The tire pressure
label lists the recommended cold t ire inflation pressures for the
vehicle at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured. For recommended tire
pressures for normal load conditions, please see chapter
=> page 310.
• The tire pressure monitoring system helps the driver to keep an
eye on tire p ressures. But the driver still has the responsib ility for
maintaining the correct tire pressure .
• If your veh icle is eq uipped w ith a standard spare ti re*, it must be
inflated to the maximum pressure specified for the vehicle .•
A pp lies to vehicles: with T ire pressu re monitor ing system
Changing a wheel
When you change a wheel, the new tire must be initial ­
ized.
Turn on the ignit ion .
- Press the
I CAR I function but ton .
- Select
Systems in the CAR menu.
- Select
Tire pre ssure mon itoring .
-Select Initialize wheels~ page 329, fig. 259 .
Programming is necessary:

Tires and wheels Ill _______________ _____.
• Afte r the t ires have been rotated on the vehicle (includi ng use o f
the sp a re t i re*),
• If tires with new wheel sensors are used .
All pressure wa rning and system malfunction indicators in the display
will be canceled .
I f a wheel change has been made , it is necessary to complete the
Initializ e wheel s function .
The tire pressure monitor ing system is not available during the
prog ramming process and no p ressure and temperat ure val ues are
displayed on the MM I display .
After you have selected the function, th e new whe els are
programmed and the act ua l pressures are stored . Th is learn ing phase
can take up to 20 minutes d riving time .•

Malfunctions
A malfunction can have various causes.

S ys tem malf uncti on
If the warning ligh t in the inst rument cl uste r flashes fo r approxi -
mately one minu te and then remain continuously illuminated and
additionally the => fig . 261 symbol appears in the d is p lay , the
tire pressure monito ring system is not available . This can have various
causes.
Vehicle OP-eration
• If the message appears at the end of the learning process, the
system c annot recognize the whee ls ins talled o n the veh icle . T his can
be because one or more wheels without a wheel sensor were
installed .
• A wheel sensor or other component may have failed .
• T he sy stem has detected more than S whee ls wi th whee l sensors
i n the ve hicle, for example when carry ing snow tires.
• A tire was changed but the
Init ialize wheel s function was not acti­
vated =>
page 330.
• Audi rep lacemen t pa rts were no t used .
• If snow chai ns are be ing used, system function can be compro ­
mised due to the shielding properties of the chains .
• Th e tire press ure monitor in g sys tem may not be ava ilable because
of a radio malfunction.
• Transmitters wi th the same freq uen cy, s uch as radio headphones
in the vehicle or radio equipment, can cause a temporary disrupt io n
of the sys tem throug h ex cessive elect romag net ic fie lds.
• Eliminate the interference if possible/if you can and then re-start
t he
Initialize wheels f unc tion. If the wa rning light comes on again,
you should contact your authori zed Audi dealer immediately to have
the problem corrected .
• Do not use commercially ava ilab le tire sealants . Otherw ise, the
elect rical components of the tire pressure mon itor ing system w ill no
longer work proper ly and the sensor for the t ire pressure monitoring
system will have to be replaced by a qualified workshop. •
