mil eage
The fol lowing driving information is continuously evaluated by the
t rip computer and can be displayed sequential ly in the instrument
cluster display.
Fuel r ang e
The estimated cruising range in miles (km) appears in the display.
This tells you how far your vehicle will be able to trave l on the
current tank of fuel and with the same driving sty le. The display
changes in increments of 6 miles (10 km).
The cruising range is ca lculated based on the fuel consumption for
the last 18 miles (30 km). If you drive conservatively, the cruising
range will increase .
Avera ge fu el mil eage
The average fuel economy in MPG (1/100 km) since you last cleared
the memory appears in this display. You can use this display to
adjust your driving technique to achieve a desired mileage.
C urr en t fu el mi leage
The instantaneous fuel consumption in m iles per gallon (1/ 100 km)
is shown in this disp lay. You can use this display to adjust your
driving technique to achieve a desired mileage .
Fuel consumption is recalculated at interva ls of 33 yards (30
meters) . When the vehicle is stationary, the most recent fuel
consumption is displayed .

Tire pressure monitoring system
General notes
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significantly
under-inflated . The TPMS on ly provides a low tire pressure warning
and does not reinflate your tires .
Accordingly, when the low tire pressure telltale illumin ates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under ­
inflated tire causes the tire to overheat and can lead to tire failure.
Under -inflation also reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping ability .
0 Note
• Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver's responsibility to maintain correct
tire pressure, even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure telltale. .,,_

• Each tire, including the spare, should be checked monthly when
cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pres­ sure label. (I f your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for those
tires.) •
TPMS malfunction indicator
Your vehicle has also been equipped with a TPMS malfunction indi ­
cator to indicate when the system is not operating properly . The
TPMS malfunction indicator is combined with the low t ire pressure
telltale. When the system detects a ma lfunction, the te lltale wi ll
flash for approximately one minute and then remain continuously il luminated . T his sequence will continue upon subsequent vehicle
starts up as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be ab le to detect or signa l low tire pressure as intended.
TPMS ma lfunctions may occur for a variety of reasons, including the
installation of replacement or alternate tires or wheels on the
veh ic le that prevent the TPMS from functioning proper ly . Always
check the TPMS malfunction telltale after replacing one or more
tires or whee ls on your ve hicle to ensure t hat the replacement or
a lternate tires and wheels a llow the TPMS to continue to function
proper ly .•
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving .
As soon as the tire pressure monitoring system senses a significant
loss of air pressure in one or severa l tires, text messages and yellow
symbo ls appear in the instrument cluster display to a lert the driver .
Controls and equip ­
ment
Dr ive r informat ion di spl ay
The , J warning light in the instrument cluster comes on when the
t ire is significantly underinflated
~ page 20 .
The warning light I also i lluminates in the case of a system
malfunction.
Be aware that t ire 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
vehicle is moving and tire pressure rises . So you should adjust tire
pressure on ly when they are
cold, when the tempera ture 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 should be checked at regular
intervals, adjusted if necessary and saved in the proper setting
(recommended pressure) ~
page 45.
The tire pressure is shown on the label located either on the driver's
s ide 8 -pi llar (visible when the door is open) or inside the fue l filler
flap .
& WARNING
• Wh en the tire pre ssure mon itor ing system warning light i s lit,

Driver inf ormati on displ ay
<£> For th e sak e of th e environm ent
Driving w ith under -inflated tires reduces fuel efficiency and tire
tread life.
[ i ] Tip s
• Each tire, incl udin 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 317.
• The factory supplied spare whee l is equipped with a sensor for
the tire pressure monitoring system. As long as the spare whee l it
not mounted, the tire pressure of this tire will not be monitored.
• The tire pressure monitoring system he lps the driver to keep an
eye on t ire pressures. But the driver stil l 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 rep laced
and, i f 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 p ressure monitoring system.
Otherwise the system w ill register a ma lfunction and a fault
message will be displayed . For more information, contact your Audi
dea ler.
• Adjust the tire pressure and store the pressure in the tire pres­
sure monitor ing system to the load you are carry ing. •

[ i ] Tip s
• 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 45.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• The ye llow symbol disappears, when the tire pressure is
corrected and the new pressure is stored in the system=:>
page 45.
• After changing a wheel or rep lacing a wheel with the spare tire
you have to adjust the tire pressures on all wheels . In addition, you
must then initialize the new tire pressures in the tire pressure moni ­
toring system=:>

Syste m malfu nc tion
If the warning light in the instrument cluster flashes for approxi­
mately one minute and then remains continuously il luminated and
additionally the
JIS => fig . 28 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 process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a whee l sensor were
insta lled .
• A wheel sensor or other component may have failed .
• During initialization the system has detected more than 4 whee ls
on the vehicle, for examp le while driving next to another car with a
tire pressure monitoring system .
• A wheel change was made but the Initialize wheel s function
=> page 46was not activated.
• Audi replacement parts were not used .
• I f snow chains are being used , system function can be compro ­
m ised due to the shielding properties of the cha ins .
• T he tire pressure monitoring system may not be available
because of a radio ma lfunction.

• Transmitters with the same frequency, such as radio head­
phones in the veh ic le or radio equipment, can cause a temporary
disruption of the system through excessive electromagnetic fields.
• Eliminate the interference if possib le/if you can and then re-start
the
Init ialize wh eels function . If the warning light comes on again,
you shou ld contact your authorized Audi dealer immediate ly to have
the problem corrected.
• Do not use commercially available tire sealants. Otherwise, the
e lectrical components of the tire pressure monitoring system will
no longer work properly and the sensor for the tire pressure moni ­
