Driver inf ormati on displ ay
[ i ] Tip s
• Each tire should be checked monthly when cold and set to the
recommended inf lation pressure as spec ified on the tire pressure
table ~
page 351 .
• The tire pressure monitoring system he lps the driver to keep an
eye on t ire pressures . But the driver stil l has the responsibility for
maintaining the correct tire pressure .
• Tire pressure must only be adjusted when the tempera ture of the
tires is about the same as ambient air temperature .
• When tires are replaced , the sensors and valves should no t be
detached or exchanged. Only the valve core needs to be rep laced
and , if necessary , the valve and the wheel electronics 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 regis ter a ma lfunction and a fault
message will be displayed . For more information, contact your
authorized Audi dea ler.
• Adjust the tire pressure and store the pressure in the tire pres ­
sure monitoring system to the load you are carrying~

Syste m malfu nc tion
If the warning light in the instrument cluster flashes for approxi­
mately one minute and then remains continuously illuminated and
additionally the
JIS => fig . 28 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 process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a whee l sensor were
insta lled .
• A wheel sensor or other component may have failed .
• During initialization the system has detected more than 4 whee ls
on the vehicle, for examp le while driving next to another car with a
tire pressure monitoring system .
• A wheel change was made but the
Initi alize wheel s function
=> page 46was not activated.
• Audi replacement parts were not used .
• If snow chains are being used , system function can be compro ­
m ised due to the shielding properties of the cha ins .
• T he 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 ic le or radio equipment, can cause a temporary
disruption of the system through excessive electromagnetic fields.
• Eliminate the interference if possib le/if you can and then re-start
the
Init ialize wh eels function . If the warning light comes on again,
you shou ld contact your authorized Audi dealer immediate ly to have
the problem corrected.
• Do not use commercially available tire sealants. Otherwise, the
e lectrical components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni ­
toring system wi ll have to be replaced by a qua lified workshop .•
