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. •

Current tire pressures are shown in green and yellow numbers. The
meaning of the co lors is as fo llows:
• Green: If current tire pressure and the specified pressure are
approximately the same, the tire pressure is shown in green .
• Yellow : If current tire pressure is too low with respect to specified
pressure, the tire pressure is shown in yellow.
[ i ] Tips
• During the learning period, tire pressure and tire temperature
are not displayed . Horizontal lines --,-- are displayed for pressure
and temperature.
• The tire pressure is shown on the label located either on the
driver's side B-pil lar (visible when the door is open) or inside the fuel
filler flap.
• The tire pressure monitoring system helps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure. •
Applies to vehicles: with Tire pressure mon itor ing system
Storing tire pressures
Correct storage of specified pressure is the basic require­
men t for reliable tire pressure monitoring.
In order for the tire pressure mo nito ring system to ope rate
appropr iately, yo u have to re -save the specified pressures
whenever yo u adjust tire pressure, for example when the
load condition of your vehicle changes. Proceed as follows:
Corr ecting t ir e pres sure
- Check the pressure in the tires (including the spare tir e*). ~

-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
I CAR I funct ion button.
- Select
Systems in the CAR menu .
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.

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 .•

Battery operation in the master key is monitored by a check light .
The check light flashes when one of the buttons on the master key
is pressed . If the check light does not flash, the battery is dead and
has to be replaced .
In addition, when the battery is dead the symbol appears in the
instrument cluster display as well as the message :
Please ch ange key battery
We recommend having the battery changed by an Audi Dealer .•

is then closed automatically =>& .
& WARNING
• After closing the rear lid, always pull up on it to make sure that
it is properly closed. Otherwise it could open suddenly when the
vehicle is moving.
• To help prevent poisonous exhaust gas from being drawn into
the vehicle, always keep the rear lid closed while driving. Never
transport objects larger than those which fit completely into the
luggage area, because then the rear lid cannot be fully closed.
• Never leave your vehicle unattended especially with the rear lid
left open. A child could crawl into the car through the luggage
compartment and pull the lid shut, becoming trapped and unable
to get out. To reduce the risk of personal injury, never let children
play in or around your vehicle. Always keep the rear lid as well as
the vehicle doors closed when not in use.
