Driver inf ormati on displ ay
The warning light n also illuminates in the case of a system
mal fu n ction.
The system continuously receives radio signals from sensors located inside each tire .
Be aware that tire 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
vehic le is moving and tire pressure rises. So you should adjust tire
pressure only when the tires are
cold, when the temperature of the
tires is roughly the same as the ambient air temperature .
In order to keep the tire pressure monitoring system properly cali ­
brated, tire pressure on al l four tires and on the spare tire * should
be checked at regular intervals, adjusted if necessary and sav ed in
the proper setting (recommended pressure) =>
page 44.
The tire pressure is shown on the tire pressure label. On USA vehi­
cles, the tire pressure label is located on the driver's side B -pi llar. On
Canada vehicles, the tire pressure labe l is located either on the
driver's side B -pil lar or inside the fuel filler flap . The tire pressu re
label lists the recommended cold t ire inflat ion pressures for the
vehic le 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 current temperatures and pressure of your tires can be viewed
i n the MMI =>
page 44.
& WARNING
• When the t ire pre ssure moni toring sy st em warning light i s lit ,
one or more of your tir es is s ignifi cantly under -infl ate d . Y ou s hould
s to p and che ck your tir es as soon as poss ible, and infl ate th em to
th e p rop er p ress ure as i ndicated on the vehicle's tire press ure
lab el
=> page 3 30 . Driving on a s ig n ific antly und er-inflated tir e
ca uses the t ire to overheat an d ca n le a d t o tir e fai lur e. U nde r- infl a-
& W ARN IN G (c ontinued )
tion a lso is likel y to imp air t he veh icle 's handling and sto pping
ability .
• Do not adju st t ire press ure when t ire temper atu re i s excessiv e.
T hi s c ould le ad to seriou s tire dam age and even cause the ti re to
bur st, w ith the additional d ange r of an accident .
Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i ] Tips
• Each tire, includin g the sp are*, should be checked monthly when
cold and set to the recommended inflation pressure as specified on
the tire pressure label=>
page 330.
• T he tire pressure monitoring system he lps the d river to keep an
eye on tire pressures . But the dr iver st ill has the responsibility for
maintaining the correct tire pressure .
• Tire 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 shou ld not be
detached or exchanged . Only the valve core needs to be replaced
and, if necessary, the va lve and the wheel electronics replaced .
• If you should put different whee ls 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 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 mon itor ing system to the load you are carrying=>

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. •

Malfunctions
A malfunction can have various causes.
Fi g. 2 9 Dis p lay :
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 .•
Electronic immobilizer
T he immob ili z er helps to prevent unauthorized use of
y o ur vehicle.
A computer chip inside your key automatically deactivates the e lec­
tr onic im mob ilizer when you insert the key in the ign iti on lock, or on
vehic les with Convenience key*, when the key is inside the vehicle .
When you remove the key from the ignition lock, or on vehicles with
Convenience key, when you remove the key from the vehicle, the
e lectronic immobilizer is automatica lly activated once again.
If an unauthor ized key was used,
SAFE is disp layed continuously in
the odometer disp lay field.
& WARNING
Always take the key w ith you when you leave the vehicle. The key
c an disarm the electronic engine immob ilizer and permit an unau ­
thori zed person to start the engine and enable oper atio n of the
vehicle sy stem s such a s power window or power sunroof leading
