In order for the tire pressure monitoring system to operate
accurately, 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:
Correct the tire pressure
- check the pressure in the tires (including the spare tire),
- adjust the air pressure as needed in accordance with the
information on the tire pressure label.

Following each intentional change in specified pressures , tire pres­
sures must be resaved .
Af ter the pressures are saved, the tire pressure monitoring system
measures the current tire pressures and saves them as the new
specified pressures .
[ i] Tips
• The tire pressure is shown on the tire pressure label. On USA
vehic les, the tire pressure label is located on the driver's side 8-
pillar. On Canada vehicles, the tire pressure labe l is located either on
the driver's side 8 -pillar or inside the fuel filler flap . The tire pressure
label lists the recommended cold tire 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 cond itions, please see chapter
~ page 297.
• The tire pressure monitoring system he lps the driver to keep an
eye on tire pressures. But the driver stil l has the responsibility for
mainta ining the correct tire pressure. •

additional ly the => fig. 44 symbol appears in the display, the
tire pressure monitoring system is not available . This can have
various causes.
• If the message appears at the end of the learning phase, the
system cannot recognize the wheels insta lled on the vehicle . This
can be because one or more wheels without a wheel sensor were
installed .
• A wheel sensor or other component may have failed.
• The system has detected more than 4 wheels in the vehicle, for
example while driving beneath another car with tire pressure moni ­
toring system .
• A tire was changed but
the => page 50, "Changing a wheel"
procedure was not activated
=> page 50.
• Audi replacement parts were not used .
• If snow chains are being used , system function can be compro ­
mised due to the shie lding properties of the chains .
• The tire pressure monitoring system may not be available
because of a radio malfunction .
• Transmitters with the same frequency , such as radio head ­
phones in the vehicle or radio equipment, can cause a temporary
dis ruption of the system through excessive el ectromagn etic fie lds.
• Try to find the cause of the interference, and then perform the
=> page 50, "Changing a wheel" procedure one more time . If this not
e liminate the prob lem , contact your authorized Audi dea ler for
assistance .
• Do not use commercially available tire sealants. Otherwise , the
electrica l components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni­
toring system will have to be replac ed by a qualified workshop. •
