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 following settings:
- Select and set a temperature between 64 °F (+22 °C) and
86 °F (+29 °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 the outside
temperature and for the intensity of the sunlight entering the
vehicle. We recommend you use the
Automatic mode=> page 112
for year -round comfort.
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This
also prevent 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.
I f 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 eliminates 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.
These settings will differ depending if the roof is opened or closed.
This way every driver will maintain his/her own personal settings
and does not have to reset them manually.
~

Warm and cold -
----------------
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.
& 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.
• Fully familiarize yourself with the proper use and function 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, switch
on ECON and contact an authorized Audi dealer to have the system
inspected.
• Repairs to the Audi air conditioner require special technical
knowledge and special tools. Contact an authorized Audi dealer for
assistance.
[ i] Tips
• Keep the air intake slots (in front of the windshield) free from ice,
snow and debris in order to maintain the proper function of the
climate control system.
• Air escapes through vents under the rear window. When placing
items of clothing on the luggage compartment cover, ensure that
the openings are not covered.
Controls and equip ­
ment
• If the inside temperature is very high (for example, if the vehicle
has been parked in sun), open the windows and allow the hot air to
escape before turning on the air conditioner. •
Controls
This overview will help you to familiarize yourself with the
air conditioning controls.

Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface
with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move. The wheel less able to transfer
power spins.
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads, the EDL cuts out temporarily. The
vehicle remains operational and behaves in the same way as a
vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto­ matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, the drive wheels can spin and reduce your ability to control your car. -Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning. This is
indicated by the ABS warning light=>
page 20. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP). When the vehicle starts up and acceler­
ates, the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface.
How the system works
ASR performs automatically, i.e. without the driver's intervention.
With the aid of the ABS sensors=>
page 276, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
power is reduced automatically until the tires find enough grip to
lock onto the road surface. The system is active across the entire
speed range.
Th e ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identical tires Any differences in rolling radius of the tires can
cause the system to reduce engine power when this is not desired.

New brake pads
Remember that new brake pads do not have a full braking
effec t during the first 250 miles (400 kilometers) after they
are installed .
New brake pads have to be "burn ished in" before they have optimal
grab =>& .
During the break -in period, you shou ld avoid putting severe loads
on the brakes . Severe loads include, for examp le, sudden hard
braking, in particular at very high speeds or, for example, on moun ­
tain passes.
& WARNING
Ne w brake p ad s don't h ave the bes t sto pp in g po we r and mu st b e

Catalytic converter
It is very important that your emission control system
(catalytic converter) is functioning properly to ensure that
y o ur vehicle is running in an environmentally sound
manner.
- Always use lead-free gasoline=> page 244, "Fuel supply".
- Never run the tank down a ll the way to empty.
- Never put too much motor o il in your engine =>
page 255,
"Adding eng ine oi l 'l:::r.11
•
- Neve r try to push -or tow -s ta rt yo ur vehic le.
The catalytic converter is an efficient "clean-up" device built into the
exhaust system of the vehicle. The catalytic converter burns many
of the po llutants in the exhaust gas before they are released into the
atmosphere.
The exc lusive use of unleaded fue l is critica lly important for the l ife
of the cata lytic converter and proper functioning of the engine.
& WARNING
• Do not p ark or op erate th e veh icle in are as w here the h ot
ex hau st sys tem m ay come in co ntac t w ith dr y gr ass, brush , fuel
s pill or other mater ial which can cau se a fire .
• Do not apply a dditi ona l u nder coating or ru stpr oofing on or
n ea r the exhau st m anifold , exhau st pipe s, ca ta lytic conv ert er or
h eat shie ld s. Dur in g d riving , the sub sta nce use d fo r und ercoa ting
coul d ove rhea t and cause a fire .
0 Note
• Be aware that just one tank filling with leaded fue l wi ll already
seriously degrade the performance of the catalytic converter.
• Do not exceed the correct engine oi l level =>
page 255.
• Do not drive until the fuel tank becomes comp letely empty . The
engine cou ld misfire. Unburned fuel could also get into the exhaust
system and this could cause the catalytic conver ter to overheat .
• Do not turn off the ignition while the vehicle is moving.
• Do not con tinue to operate your vehicle under these conditions,
as otherwise fuel can reach the cata lytic converter . This cou ld result
in overheating of the converter, requiring its rep lacement .
• To assure eff icient operation of the Em ission Control System:
- Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty
& Maintenance
booklet. •
