life, and may affect the veh ic le's handling and stopping abi lity.
Please note that the TPMS is not a substitute for proper tire mainte­
nance, and it is the driver's responsibi lity to maintain correct tire
pressure, even if under-inflation has not reached the leve l to tr igger
illumination of the TPMS low tire pressure tellta le.
Your veh icle has a lso been equipped with a TPMS malfu nction indi­
cator to indicate when the system is not operating properly . The
TPMS malfunction indicator is combined w ith the low tire press ure
telltale . When the system detects a ma lfunction , the telltale wi ll
fl ash for approximately one minute and then remain continuously
illum inated . This sequence will continue upon subsequent vehicle
start -ups as long as the ma lfunction exists.
When the ma lfunctio n indicator is i llum inated, the system may not
be ab le to detect or signa l low tire pressure as intended . TPMS
malfunctions may occ ur for a var iety of reasons, i nclud ing the
installation of replacement or alternate tires or wheels on the
vehic le that prevent the TPMS from f unctioning proper ly . Always
check the TPMS malfunction tellta le after replac ing one or more

Introduction
The tire pressure monit oring system m onitors air pressure
in all four road wheels and the spare tire* while the
vehicle is movin g.
As soon as the tire pressure moni toring system se nses a signi ficant
loss of air pressure in one or severa l tires, text messages and yellow
symbo ls appear in the inst rume nt cluster d isplay to aler t t he driver .
T he
(l) warning light in the instrument c luster comes on when the
t ire is sig nificant ly underinflated
=> page 20 .
Controls and equip­
ment
Driver information di splay
The warning light U) also i lluminates in the case of a system
mal fu ncti on.
The system continuous ly receives rad io signa ls from sensors
located inside each tire .
Be aware that t ire p ressu re is also dependen t on the tempera ture of
the tire . For every
18 °F (1 O °C) increase in tire temperature, tire pres­
sure increases by about 1 .5 psi (0 .1 bar). The tire warms up wh ile the
vehicle is moving and t ire pressure rises . So you should adjust tire
pressure only when the t ires are
cold, when the temperature 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 and on the spare tire* should
be checked at regular intervals, adjusted if n ecessary and saved in
the proper setti ng (recommended
pressure) => page 44.
The tire pressure is shown on the tire pressure label. On USA vehi ­
cles, the tire pressure labe l is located on the drive r's s ide B -p ill ar. On
Canada vehicles, the tire pressure labe l is located either on the
driver's side B -pillar o r inside the fuel fi ller flap. The t ire press ure
label l ists t he recommended cold tire inflat io n pressures for t he
vehic le at its maximum capacity weight and the tires that were on
your ve hicle at the time it was manufactured . For recommended tire
pressures for normal load condit ions, please see chapter
=> page 328 .
The current temperatures and pressure of your tires can be viewed
in the M MI
=> page 43 .
& WARNING
• When the tire pre ssure monitoring system warning light i s lit ,
one or more of your tires is signifi cantly under -infl ated . You should
stop and check your tires a s soon a s po ssible , and inflate them to
the proper pre ssure a s indi cated on the vehi cle' s tire pre ssure
label
=> page 328 . Driving on a significantly under -inflated tire

tion also is likely to impair the vehicle's handling and stopping
ability.
• Do not adjust tire pressure when tire temperature is excessive .
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
W For the sake of the environment
Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i) Tips
• Each tire, including the spare*, should be checked monthly when
cold and set to the recommended inflation pressure as specified on
the tire pressure label
=> page 328.
• 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 .
• 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 should not be
detached or exchanged. Only the valve core needs to be replaced
and, if necessary, the valve and the wheel electronics replaced.
• If you should put different wheels 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 malfunction and a fault
message will be displayed. For more information, contact your
authorized Audi dealer.
• Adjust the tire pressure and store the pressure in the tire pres ­
sure monitoring system to the load you are
carrying => page 328. •
Significant loss of air pressure ( )
The yellow symbol appears in the event of a significant
loss of air pressure.

message
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 sensor).
Stop driving as soon as possible without endangering
yourself or other drivers on the road.
- Inspect the tire or tires.
Change the tire if
necessary:::::, page 351.

The j warning light in the instrument cluster comes on when the
tire is significantly underinflated.
In addition, the tire symbo l

!CHECK] 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 43.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient a ir 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 tire pressures on
all 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 => page 42, fig. 25
or=>
page 42, fig. 26 will appear if the pressure is too low.•

Turning the key counter-clockwise to position @ will release the
rear lid and cause it to rise slightly. In this position the key cannot
be pulled out of the lock cylinder.
Turning the key
clockwise to the horizontal position @ and pulling
