should de termine the proper tire inflation pressure for those
tires.) •

Your vehic le has also been equipped with a TPMS ma lfunction indi ­
cator to indicate when the system is not operating properly. The
TPMS ma lfunct ion indicator is combined with the low tire pressure
telltale . When the system detects a ma lfunction, t he tellta le wi ll

il lum inated. T his sequence wil l continue upo n subsequent veh icle
star ts up as long as the malfunction exists.
When the ma lfunc tion ind icator is ill uminated, the system may not
be able to detect or signal low tire pressure as intended .
TPMS malfunctions may occur for a variety of reasons, including the
installation o f rep lacement or a lternate tires or wheels on the
vehic le that prevent the TPMS from functioning properly . A lways
check t he TPMS malfunction tellta le after replac ing one or more
tires or whee ls on your v ehicle to ensur e that the replacement or
a lternate t ires and wheels al low the TP MS to continue to function

Introduction
T he tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving.
As soon as the tire pressure monito ring system se nses a significant
loss of air pressure in one or several tires, text messages and yel low
symbo ls appear in the instrument clus ter disp lay to a lert the driver.
The
(l) warning light in the instrument cluster comes on when the
t ire is significa ntly under inflated.
The warning light
(l) also lights up during a system failure .
When the whee l is turning, the system receives radio signals from
sensors located inside each tire.
A factory spare wheel is delivered with sensor . However, the spare
whee l is not checked by the ti re pressure monitoring sys tem. Such
monitoring can on ly occur after the spare wheel has been insta lled
and
initia lized => page 50.
Be aware that t ire pressure is a lso dependent o n the temperature of
the tire . For every 18 °F (1
O °C) increase in tire temperature, tire pres ­
su re increases by about 1.5 psi (0 .1 barl. The tire warms up wh ile the
vehic le is moving and t ire pressure rises. So you should adjust tire
pressure only when they are
cold, when tire temperature is roughly
the same as ambient air temperature .
I n order to keep the tire pressure moni toring system prope rly ca li­
brated, tire pressure on all four tires shou ld be checked at regular
intervals, adjusted if necessary and saved in the proper sett ing
(reco mmended
pressure) => page 48.
The tire pressure is shown on the tire pressure label. On USA vehi ­
cles, the tire pressure label is located on the dr iver's side B -pillar. On
Canada vehicles, the tire pressure labe l is located either on the
driver's side B -p illar o r inside the fue l fi ller flap. The tire pressure
label l ists the recommended cold tire inflation pressures for the
vehic le at its maximum capacity weight and the tires that were on
your vehicle at the t ime it was manu factured . For recommended tire
~

pressures for normal load conditions, p lease see chapter
~ p ag e 297 .
& WARNING
• When the tire pre ssure monitoring sy stem warning light i s lit ,
one or more of your tires is sign ifi cantly under-inflated . You should
s top and check your tire s as soon as possible , and inflate them to
the p rope r pres sure a s indicated on the vehicle's tire pre ssure
label
~ page 297 . Driving on a significantly under -inflated tire
c ause s the t ire to overheat and can lead to tire failure . Under -infla ­
tion also is likely to impair the vehicle's handling and stopping
ability .
• Do not adjust tire pre ssure when tire temperature is excessive.
Thi s could lead to serious tire damage and even cause the tire to
burst , with the additional danger of an ac cident .
<£' For the sake of the environment
Driving wi th under -inflated tires reduces fuel efficiency and tire
tread life.
[ i ] Tips
• Each tire should be checked mon th ly when cold and set to the
recommended inf lat ion pressure as specified on the tire pressure
table~ page 297 .
• The tire pre ssur e monito ring system he lp s the drive r to kee p
t rack of the tire pressures. But the d river s til l has the responsibi lity
for maintaining the correct tire p ressure .
• Tire pressure must only be adjusted when th e temperature of the
t ires is about the same as am bien t air temperatu re .
• When tires are replaced , the sensors and va lves must not be
detached or exchanged. Only the valve co re needs t o be rep laced
and, if necessary, the valve and the wheel e lectronics replaced.
Controls and equip ­
ment
Driver information display
• If you should put different whee ls and tires on your vehic le (e .g.
win ter wheels a nd ti res), you must be certa in that the wheels a nd
tires are compatible with the t ire pressure monitoring system .
O therwise the system will register a ma lfunction and a fau lt
message will be displayed. For more information, contact your Audi
dea ler .•

If the ~ warning light in the instrument cluster comes on
and then the

[ i ] Tips
• In the case of an intentional loss of air pressure, for examp le,
when re -adjusting tire pressure, this has to be stored again after ­
wards~ page 48.
• Tire pressure must only be adjusted when the temperature of the
t ires is about the same as ambient air temperature.
• The yellow symbol disappears, when the tire pressure is
corrected and the new pressure is s tored in the system
~ page 48 .
• After changing a wheel you have to adjust the tire pressures on
all wheels. In addition, you must then initia lize the new tire pres­
sures in the tire pressure monitoring
system ~ page 50. •

additional ly the => fig. 44 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 phase, the
system cannot recognize the wheels insta lled on the vehicle . This
can be because one or more wheels without a wheel sensor were
installed .
• A wheel sensor or other component may have failed.
• The system has detected more than 4 wheels in the vehicle, for
example while driving beneath another car with tire pressure moni ­
toring system .
• A tire was changed but
the => page 50, "Changing a wheel"
procedure was not activated
=> page 50.
• Audi replacement parts were not used .
• If snow chains are being used , system function can be compro ­
mised due to the shie lding properties of the chains .
• The tire pressure monitoring system may not be available
because of a radio malfunction .
• Transmitters with the same frequency , such as radio head ­
phones in the vehicle or radio equipment, can cause a temporary
dis ruption of the system through excessive el ectromagn etic fie lds.
• Try to find the cause of the interference, and then perform the
=> page 50, "Changing a wheel" procedure one more time . If this not
e liminate the prob lem , contact your authorized Audi dea ler for
assistance .
• Do not use commercially available tire sealants. Otherwise , the
electrica l components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni­
toring system will have to be replac ed by a qualified workshop. •

_& WARNING
• Do not leave children unattended in the vehicle, especially with
access to vehicle keys. Unsupervised use of the keys can result in
starting of the engine and use of vehicle systems such as power
windows, etc. which could result in serious injury.
• Remember -you can still open or close the power windows for
about ten minutes after the ignition is switched off. Only when
either of the front doors are opened are the power windows
switched off.
• Be careful when closing the windows. Check to see that no one
is in the way, or serious injury could result!
• Always remove the ignition key whenever you leave your
vehicle.
• If you lock your vehicle from the outside, no one, especially chil­
dren, should remain in the vehicle.
• Do not stick anything on the windows or the windshield that
may interfere with the driver's field of vision. •
Switches in the driver's door
The driver can operate all windows.
If the respective switch is pushed or pulled the window will
