If the ' ' warning light in the instrument cluster=:> page 20
illuminates and then the symbol appears in the display
=:> fig. 25 or=:> fig. 26, this means the tire pressure is too low
in one or several tires (including spare tire* with se nsor).
- Stop driving as soon as possible without endangering
yourself or other drivers on the road.
- Inspect the t ire or tires .

The warning light in the instrument cluster comes on when the
tire is significantly underinflated.
In addition, the tire symbol appears in the display together with
the message
Please check tire pressure=> fig. 25.
After a few seconds, the message disappears again=> fig. 26 . If you
would like to show the message again, press the [ CH ECK] button.
[ i ] Tips
• In the case of an intentional loss of air pressure, for example,
when re -adjusting tire pressure, this has to be stored again after ­
wards =>
page 44.
• Current information about tire pressures and temperatures can
be scanned in MMI
~ page 44.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• The yellow symbol disappears, when the tire pressure is
corrected and the new pressure is stored in the system~
page 44.
• After changing a wheel you have to adjust the t ire pressures on
al l whee ls. In addition, you must then initialize the new tire pres­
sures in the tire pressure monitoring system~
page 45.
• If your vehicle is equipped with a spare tire* with a wheel sensor,
the tire will be monitored and the display symbols~ fig. 25 or
~ fig. 26 will appear if the pressure is too low. •
Vehicle care I I irechnical data

-Adjust air pressure as needed in acco rdance with the
informat io n on the label located either on the driver's
side B -pillar (visible w hen the door is open), inside the
fuel filler flap and addi tionally in t he manua l.
Saving tir e pres sur es
- Tur n on the ignition.
- Press the

Selec t
Tire p ressure monitoring.
-Select Store curr. tire pres sures :::} page 44, fig. 27 .
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 current tire pressures and saves them as the new
specified pressures.
[ i ] Tip s
• T he t ire 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 e ither 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 conditions, please see chapter
=> page 330 .
• The tire pressure mon itoring system he lps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure.

Dr ive r informat ion di spl ay
• I f your vehic le is equipped with a standard spare tire *, it must be
inflated to the maximum pressure specified for the veh icle. •

the spare tire*),
• I f tires with new wheel sensors are used.
A ll pressure warning and system ma lfunction indicators in the
display will be canceled.
I f a wheel change has been made, it is necessary to complete the
Initi aliz e w heel s function.
The tire pressure monitoring system is not available during the programming process and no pressure and temperature values are
displayed on the MMI display.
After you have selected the function, the new whee ls are
programmed and the actual pressures are stored. This learning
phase can take up to 20 minutes driving time. •

Malfunctions
A malfunction can have various causes.

S ystem m alfun ction
If the l · warning light in the instrument cluster flashes for approxi ­
mately one minute and then remain continuously il luminated and
additional ly the
-r J ~ fig . 29 symbo l appears in the display, the
tire pressure monitoring system is not ava ilable . Th is 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 wheel sensor were
installed.
• A wheel sensor or other componen t may have failed.
• The system has detected more than 5 whe els with wheel sensors
in the vehicle, for example when carrying snow tires.
• A tire was changed but the
Initiali ze wheels function was not
activated
=:> page 45.
• Audi replacemen t parts were not used .
• 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 malfunction . • T
ransmitters with the same frequency, such as radio head­
phones in the vehicle or radio equipment, can cause a temporary
disruption of the system through excessive electromagnetic fields .
• Eliminate the interference i f possible/if you can and then re-start
the
I n itia lize w heel s function . If the warning light comes on again,
you shou ld contact your authorized Audi dealer immediately to have
the problem corrected .
• Do not use commercial ly availab le tire sealants . Otherwise, the
electrical components of the tire pressure monitoring system will
n o l onger work properly and the sensor for the tire p ressure moni ­
toring system wi ll have to be replaced by a qua lified workshop .•
