lified service station can inter­
pret the code and perform the necessary repair. •
Electronic speed limiter
Your vehicle may be factory equipped with tires t hat are rated for a
maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your vehicle. To reduce the risk of sudden t ire
failure and loss of control if the vehicle is operated at excessive
speeds, your vehicle also has an electronic speed limiter. The e lec­
tronic speed limiter prevents your vehic le from going faster than the
tire speed rating . For more
information => page 336.
lf the veh ic le approaches the tire speed rating, the engine control
unit wi ll turn off the fue l injectors. You will notice an immediate loss
of engine power and a drop in road speed.
If the engine contro l unit receives faulty vehic le road speed signals,
the Ma lfunction Indicator Lamp (MIU

Auto Check Control
Introduction
T he Auto -Check contro l monitors the function of certain vehic le
features and components. I t simply makes sure these features and
components are working properly. The Auto -Check control works as
l ong as t he igni tion is on, as wel l as whenever the vehicle is
driven. ~

Driver inf ormation displ ay
• Green: If current tire pressure and the spec ified pressure are
approximate ly the same, t he tire pressure is shown in green.
• 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
filler flap .
• 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. •

• The driver can lower or raise the power side blinds * in the side
windows by using switches

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 following 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

Warm and cold -
----------------
energy are temporarily cut back or switched off~ page 274 .
Heating sys tems in par ticular require a great dea l of energy. If yo u
not ice, for example, that the seat *, w indshield * or rear w indow
hea ting is no t heat ing, they have bee n t em por arily c ut b ack or
switched off by
energy management . These systems are availabl e
aga in as soon as the ene rgy ba lance has bee n restor ed.
& WARNING
Reduced visibility is dangerous and can cause accidents .
• For safe driving it is very important that all windows be free of
ice , snow and condensation.
• Completely familiarize yourself with the proper use and func­
tion of the heating and ventilation system and especially how to defog and defrost the windows .
• Never use the windshield wiper /washer system in freezing
weather until you have warmed the windshield first , using the
heating and ventilation system. The washer solution may freeze
on the windshield and reduce visibility .
0 Note
• If you suspect that the air conditioner has been damaged, turn
