Trip computer
Introduction
The trip computer gives you information on current and
average fuel mileage, average speed, fuel range and
driving time.
Fig. 21 Trip comput er
di sp lay : Average fuel
mil eage
The following driving information is continuously evaluated by the
trip computer and can be displayed sequential ly in the instrument
cluster display.
Fuel range
The estimated cruising range in miles (km) appears in the display.
This tells you how far your vehicle will be able to travel on the current tank of fuel and with the same driving style. The display
changes in increments of 6 miles (10 kml.
The cruising range is calculated based on the fuel consumption for
the last 18 miles (30 km). If you drive conservative ly, the cruising
range will increase.
Average fuel mileage
The average fuel economy in MPG (1/100 km) since you last cleared
the memory appears in this display . You can use this disp lay to
adjust your driving technique to achieve a desired mileage .
Current fuel mileage
The instantaneous fuel consumption in miles per gallon (1/100 km)
is shown in this display. 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
metres). When the vehic le is stationary, the most recent fuel
consumption is displayed.
Average speed
The average speed in mph (km/h) since the last time the display was
reset appears in the display.
Elapsed time
The length of time that you have been driving since you last reset
the memory appears in this display .
[ i] Tips
• Fuel consumptions (average and current), range and speed are
displayed in metr ic units on Canadian models.
• All stored values will be lost if the vehicle battery is
disconnected .•

Memories
The trip computer is equipped with two fully automatic
memories.
Fig . 22 Trip computer
display: memory level 1
You can switch between the trip computer 1 and 2 by pressing the
Reset button
@ =>fig. 23.
You can tell which memory level is currently active by the number in
the
display => fig. 22. The data from the single -trip memory
(memory level 1) is being displayed if a
1 appears. If a 2 is shown,
then the data from the total -trip memory is being displayed
(memory level 2).
Single-trip memory (Trip computer 1)
The single-trip memory stores the trip information from the time the
ignition is turned on until it is turned off. If the trip is continued
within 2 hours from the time the ignition was turned off, the new
data will be included in the calculation of the current trip informa ­
tion. If the trip is interrupted for
more than 2 hours the memory is
reset automatically .
Total-trip memory (Trip computer 2)
Unlike the single-trip memory, the total -trip memory is not reset
automatically . This permits you to evaluate your driving data for the
entire period between manual resets .•

Tire pressure monitoring system
General notes (l)
Each tire, including the spare {if provided), should be checked
monthly when co ld and in flated to the inflation pressure recom ­
mended by the vehicle manufacturer on the vehicle p lacard or tire
inf lation pressure labe l. (If your vehicle has tires of a different size
than the size indicated on the vehicle placard or tire inflation pres­
sure labe l, you should determine the proper tire inf lation pressure
for those
tires.!
As an added safety feature , your vehicle has been equipped with a
t ire pressure monitoring system {TPMS) that illuminates a low t ire
pressure telltale when one or more of your tires is significantly
under -inf lated. Accordingly, when the low t ire pressure te lltale i llu­
minates , you should stop and check your tires as soon as possible,
and inf late them to the proper pressure . Driving on a significantly
under-inf lated tire causes the tire to overheat and can lead to tire
~

Driver information display
& WARNING (continued)
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.

symbol without
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
) appears in the display together with
the message
Please check tire pressure => page 42, fig. 25.
Af ter a few seconds, the message disappears again:::>
page 42,
fig. 26. If you would like to show the message again, press the
!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.•

• Yellow : If current tire pressure is too low with respect to specified
pressure, the tire pressure is shown in yellow.
[ i ] Tips
• During the learn ing period, t ire pressure and t ire 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-pi llar (visible when the door is open) or ins ide the fuel

• The tire pressure monitor ing system he lps the driver to keep an
eye on tire pressures . But the driver stil l has the responsibility for
maintaining the correct t ire pressu re .•
Storing tire pressures
Correct storage of specified pressure is the basic require­
ment for reli able tire pressure moni toring .
In order for the tire pressure monitor ing system to o perate
appropr iately, you have to re-save the specified p ressures
whenever you adjust tire pressure, for example when the load condition of your vehicle changes . Proceed as fo llows :
Correcting tire pressure
-Check t he pressure in the tires ( includin g the spare tire*).
-Ad just air pressure as needed in accordance with the
informat io n on the label loca ted either on the d river 's
side B- pillar (visible whe n the do or is ope n), ins ide the
f u el fill er flap a nd a ddit ionally in the manua l.
Saving tire pressur es
-Tur n on the ignition .
-Press the I CAR] fu nct ion button .
-Select Systems in the CAR me nu.
-Selec t Tire pressure monitoring .
-Select Store curr. tire pressures=> page 43, fig. 27.
A ll pressure warning indicators in the display wi ll be cance led .
Following each intentional cha nge in speci fied pressures, tire pres ­
sures must be resaved.
Afte r the pressures are saved, the tire pressure monitoring system
measures the current t ire pressures and saves them as the new
specified pressures .
[ i] Tip s
• T he tire pressure is shown on the tire pressure label. On USA
veh ic les, the tire pressure label is loca ted on the driver's side B­
pillar . On Canada vehicles, the tire pressure labe l is located either on
t he dr iver's side B -p illar or i nside the fuel filler flap . The t ire pressure
label lists the recommended cold tire inflation pressures for the
vehic le at its maximum capacity weight and the tires tha t were on
your vehicle at the time it was manufactured . For recommended tire
pressures for normal load conditions, please see chapter
=> page 328.
• The tire pressure monitoring 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.
• If your vehic le is equipped with a standard spare tire *, it must be
inflated to the maximum pressure spec ified for the vehicle. •

Changing a wheel When you change a wheel, the new tire must be initial­
ized.
Turn on the ignition.
Press the
I CAR I function button.
- Select
Systems in the CAR menu .
- Selec t
Tire pressure monitoring .
-Select Initialize wheels ~ page 43, fig. 27.
Programming is necessary:
• After the tires have been rotated on the vehicle (including use of
the spare tire*),
• If tires with new wheel sensors are used.
All pressure warning and system malfunction indicators in the
display will be canceled.
If a wheel change has been made, it is necessary to complete the
Initialize wheels function.
Th e tire pressure monitoring system is not available dur ing the
programming process and no pressure and temperature values are
displayed on the MMI display.
After you have selected the funct ion, the new wheels are
programmed and the actual pressures are stored. This learning
phase can take up to 20 minutes driving time.•

additional ly the
=> fig. 29 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 wheel sensor were
insta lled .
• A wheel sensor or other component may have failed.
• The system has detected more than 5 wheels with wheel sensors
in the vehicle, for example when carrying snow tires.
• A tire was changed but the
Initialize wheels function was not
