& WARNING
• When the tire pressure monitoring system warning light is lit,
one or more of your tires is significantly underinflated. You should
stop and check your tires as soon as possible , and inflate them to
the proper pressure as indicated on the vehicle's tire pressure
label =>
page 246 . Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire failure. Underinfla­
tion also is likely to impair the vehicle's handling and stopping
ability.
• 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.
~ For the sake of the environment
Driving with underinflated tires reduces fuel efficiency and tire
tread life.
[ i] Tips
• Each tire, including the spare , 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 246.
• Th e 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 monitor tire
pressures, but the driver is still responsible for maintaining the
correct tire pressure.
• Tir e 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.
• Th e tire pressure monitoring system on your Audi was calibrated
using tires with the "AO" or "RO" identification. We recommend
using these tires.
• 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
authorized Audi dealer.
• Adjust the tire pressure and store the pressure in the tire pres­
sure monitoring system to the load you are carrying .
• For Declaration of Compliance to United States FCC and Industry
Canada regulations => page

page 8, fig . 2 ® ·
[ i ] Tip s
• In the case of an intentiona l loss of air pressure, such as when
readjusting tire pressure, the pressure must be stored again after ­
ward =>
page 265.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• The ye llow symbol disappears when the tire pressure is
corrected and the new pressure is stored in the system=>
page 265.
• After changing a wheel or rep lacing a wheel with the spare tire
you have to adjust the tire pressures on all wheels . In addition, you
must then initialize the new tire pressures in the tire pressure moni ­
toring system=>
page 266. •

In o rder for the tire pressure monitoring system to ope rate
appr opria tely, you have to re-save the specified pressures
whenever you adjust tire pressures, such as when the load
condition of yo ur veh ic le changes . Proceed as follows :
Corr ec ting tir e pressure
- Check the pressure in t he tires .
- Adjust air pressure as needed to comp ly with t he infor-
mation on the label located on the label located either on
the driver's side 8 -pillar or on the inside of the fuel filler
flap .
Saving tire pressur es
- Turn on the ignition .

• A wheel sensor or other component may have failed.
• During initia lization the system has detected more than 4 wheels
on the vehicle, for example while driving next to another car with a
tire pressure monitoring system.
• A wheel change was made but the button
=> page 265, fig. 179
was not pressed.
• Audi Genuine Parts were not used for parts replacement.
• If snow chains are being used, system function can be compro­
mised due to the shielding properties of the chains.
• The tire pressure monitoring system may not be available
because of a radio ma lfunction.
• Transmitters with the same frequency, such as radio head­
phones in the veh icle or radio equipment, can cause a temporary
disruption of the system through excessive electromagnetic fields.
