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.

The speed warning 2 symbol, 8, (USA models)/ 8, (Canada models)
appears in the disp lay when you exceed the stored speed limit.
Unlike warning 1, it wil l not go out until the vehicle speed drops
below the s tored speed limit .

you should sti ll watch the speedometer to make sure you are not

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 .•

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.

To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts of
