• Each tire, including the spare, should be checked monthly when
cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pres­ sure label. (I f your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for those
tires.) •
TPMS malfunction indicator
Your vehicle has also been equipped with a TPMS malfunction indi ­
cator to indicate when the system is not operating properly . The
TPMS malfunction indicator is combined with the low t ire pressure
telltale. When the system detects a ma lfunction, the te lltale wi ll
flash for approximately one minute and then remain continuously il luminated . T his sequence will continue upon subsequent vehicle
starts up as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be ab le to detect or signa l low tire pressure as intended.
TPMS ma lfunctions may occur for a variety of reasons, including the
installation of replacement or alternate tires or wheels on the
veh ic le that prevent the TPMS from functioning proper ly . Always
check the TPMS malfunction telltale after replacing one or more
tires or whee ls on your ve hicle to ensure t hat the replacement or
a lternate tires and wheels a llow the TPMS to continue to function
proper ly .•
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving .
As soon as the tire pressure monitoring system senses a significant
loss of air pressure in one or severa l tires, text messages and yellow
symbo ls appear in the instrument cluster display to a lert the driver .
Controls and equip ­
ment
Dr ive r informat ion di spl ay
The , J warning light in the instrument cluster comes on when the
t ire is significantly underinflated
~ page 20 .
The warning light I also i lluminates in the case of a system
malfunction.
Be aware that t ire pressure is also dependent on the temperature of
the tire . For every 18 °F (10 °C) increase in tire temperature, tire pres ­
sure increases by about 1 .5 psi (0 .1 bar). The tire warms up while the
vehicle is moving and tire pressure rises . So you should adjust tire
pressure on ly when they are
cold, when the tempera ture of the tires
is roughly the same as the ambient air temperature.
I n order to keep the tire pressure monitoring system properly cali ­
brated, tire pressure on all four tires should be checked at regular
intervals, adjusted if necessary and saved in the proper setting
(recommended pressure) ~
page 45.
The tire pressure is shown on the label located either on the driver's
s ide 8 -pi llar (visible when the door is open) or inside the fue l filler
flap .

Syste m malfu nc tion
If the warning light in the instrument cluster flashes for approxi­
mately one minute and then remains continuously il luminated 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 Initialize wheel s function
=> page 46was not activated.
• Audi replacement parts were not used .
• I f 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 .•
