Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
The speed warning system warns the driver if he exceeds a previ ­
ously stored maximum speed . A warning tone wi ll sound as soon as
the vehicle speed exceeds the set speed by about 3 mph (3 km/h) . At
the same time, a warning symbol appears in the display.
The speed warning system has
t wo w arning th reshold s that func­
tion independently of each other and that have somewhat different
purposes:
S p ee d wa rning 1 B (U SA mod els)/ 8 (Ca na d a mo dels)
You can use speed warning 1 to set the maximum speed while you
are driving. This setting will remain in effect until you turn off the
ignition, assuming that you have not changed or reset the setting.
The speed warning symbol
8 (USA models)/ 8 (Canada models) in
the warning 1 disp lay appears when you exceed the maximum
speed. It goes out when the speed falls be low the stored maximum
speed.
The speed warning symbol will also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. However, this does no t reset the stored maximum
speed .

S pee d war ning 2
8. (U SA models)/ 8. (C an ad a m od els)
Storing warning 2 is recommended if you always want to be
reminded of a certain speed, for example when you are traveling in
a country that has a general maximum speed limit, or if you do not
want to exceed a specified speed for winter tires.

Trip computer
Introduction
The trip computer gives you information on current and
average fuel mileage, average speed, fuel range and
driving time.
F ig . 2 1 Trip co m pute r
d is pl ay : Ave ra ge fuel
mil eag e
The fol lowing driving information is continuously evaluated by the
trip computer and can be displayed sequentially in the instrument
cluster display .
Fuel range
The estimated cruising range in miles (km) appears in the display .
T his tells you how far your vehic le will be ab le to travel on the _.,

current tank of fuel and with the same driving style. The display
changes in increments of 6 miles (10 km).
The cruising range is calculated based on the fuel consumption for
the last 18 miles (30 kml. If you drive conservatively, the cruising
range will increase.
Average fuel mileage
The average fuel economy in MPG (1/100 km) since you last c leared
the memory appears in this display . You can use this display 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 intervals of 33 yards (30
metres). When the vehic le is sta tionary, 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 metric units on Canad ian models .
• All stored values wil l be lost if the vehicle battery is
disconnected .•

Memori es
The trip computer is equipped with two fully automatic
memones.
Fig . 22 Trip computer
display: memory level 1
You can switch between the trip computer 1 and 2 by pressing the
Reset button
@ ~ page 40, 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 disp layed
(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 .•
Vehicle care I I irechnical data

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.

• 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=>

Warm and cold
Climate controls
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the follow ing settings:
- Set the temperature to 75 °F (+23 °C).
- Press the !AUTO
I button.
With this setting, you attain maximum comfort in the least amount
of time. Change this setting, as desired, to meet your personal needs.
The climate controls are a combination of heating, ventilation and cooling systems, which automatically reduce humidity and cool the
air inside your vehicle.
The air temperature, air flow and air distribution are automatically
regulated to achieve and maintain the desired passenger compart­
ment temperature as quickly as possible.
The system automatically compensates for changes in outside
temperature and for the intensity of the sunlight entering the
vehicle. We recommend you use the
Automatic mode=> page 117
for year-round comfort.
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This also prevents the windows from fogging up.
When the outside temperature is high and the air is very humid,
condensation from the evaporator may drip under the vehicle. This
is normal and does not indicate a leak. If the outside temperature is low,
the fan normally only switches to
a higher speed once the engine coolant has warmed up sufficiently.
The air conditioner temporarily switches off when you drive off from
a standstill using full throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high, so that the engine can be adequately cooled under extreme
loads.
Air pollutants filter
The air pollutants filter (a combined particle filter and activated
charcoal filter) reduces or prevents outside air pollution (dust, or
pollen) from entering the vehicle.
The air pollutants filter must be changed at the intervals specified
in your Warranty
& Maintenance booklet, so that the air conditioner
can properly work.
If you drive your vehicle in an area with high air pollution, the filter
may need to be changed more frequently than specified in your
Audi Warranty
& Maintenance booklet. If in doubt, ask your autho­
rized Audi Service Advisor for advice.
Key coded settings
The air conditioner settings selected are automatically stored and
assigned to the key being used. When the vehicle is started, the air
conditioner automatically selects the settings assigned to that key.
This way every driver will maintain his/her own personal settings
and does not have to reset them manually.
If a different driver uses your key and changes the air conditioner
settings, the latest adjustments will erase and replace the settings
you have stored.
Energy management
To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts of

the outside air drops, fresh air is supp lied to the veh icle interior
again .
In the event that the windows fog up during automatic air recircula­
tion, you must press the@ button immediately.
Under certa in operating cond itions, automatic air recirculation is
switched off automatically. With outside temperatures below about
-8 °C and in the ECON mode, automatic air recirculation is limited to
15 seconds. •
Synchronization
One climate control setting for all seats .
With synchronization active, the driver's or the passenger's settings
are adopted for the other seats . All the other settings that were
made are transferred to the other seats. This includes all the climate
control settings right down to the heated seats .
If a different setting is selected at a "synchron ized seat", synchroni ­
zation is cancelled. •

The temperature of the air leaving the center vents can be
changed to differ from the temperature setting .
