General
The basic settings for the climate control are performed in
the(SETUP] menu.
Fig. 141 MMI display:
Setup climate control
The basic settings for the air conditioning can only be made
with MMI turned on.
- Press the !SETUP] button in the controls to access the
menu.
- Select the desired function using the control knob (driver
or passenger) in the air conditioning controls.
The following functions can be selected:
• ECON
~ page 126
• Automatic recirculation ~ page 126
• Synchronization ~ page 127
• Center air vent~ page 127
• Rear seat operation* ~ page 127
• Solar operation* ~ page 127•
ECON
The ECON mode helps to save fuel.
The air conditioning is turned off in ECON mode. "ECON" means
"Economy". By switching off the air conditioning (compressor), you
save fuel.
Please note that vehicle interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is not cooled or
dehumidified.
If the vehicle interior becomes too hot or if the windows fog up,
ECON mode should be turned off. As soon as the
( AUTO ] button in
the air conditioning controls is pressed, the system automatically leaves the ECON mode, and the air conditioning compressor is
turned on again .•
Automatic recirculation mode
An air quality sensor detects increased concentrations of
pollutants in the outside air and automatically switches
to recirculation mode.
We recommend that you always keep automatic air recirculation ON
to prevent polluted outside air from entering the vehicle interior.
If the
air quality sensor located in the air conditioning system
detects polluted outside air, the sensor decides whether the air
pollution can be reduced by the factory-installed pollutant filter or
whether it is necessary to switch to air recirculation . With heavy
concentrations of pollutants, the air conditioning system is
switched automatically to recirculation mode and the supply of
outside air is blocked. As soon as the concentration of pollutants in ..

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 21. •
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 274, 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.
The 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.

Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending largely on operating conditions and driving habits=>& .
On vehicles that are either driven mostly in stop-and-go city traffic
or are driven hard, the brake pads should be checked by your autho
rized Audi dealer more often than specified in the
Warranty & Main- ~
vidual components. It regulates consumption, so that more elec
trical energy is not being used than is being genera ted and ensures
an optimal state of charge for the battery.
[ i ] Tips
• But even energy management cannot negate the limits of
physics. Consider that the power and life of a battery are limited.
• If starting ability is threatened, you are informed by a warning
~ page 277, "Driver notification in the instrument cluster
display". •
What you should know
The highest priority is given to maintaining starting capa
bility.
The battery is severely taxed in short -distance driving, in city traffic
and during the cold time of year . Abundant electrical energy is
required, but only a little is generated . It is also critical if the engine
is not running and e lectrical components are turned on. In this
instance energy is being consumed but none is being generated .
It is in precisely these situations that you wi ll notice energy manage
ment actively regulating the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of several days or
weeks, electrical components are gradually cut back or switched off.
This reduces energy consumption and maintains starting capability
over a longer period.
Be aware that when you unlock your vehicle, some of the conve
nience functions may not operate, such as the Convenience key, the
remote control or the power seat adjustment. The convenience
functions will be available again when you turn on the ignition and start the engine.
Controls and equip ment Safety first Vehicle operation
Intelligent technology
With the
engine turned off
If you listen to the radio, for examp le, with the engine turned off or
use other MMI functions, the battery is being discharged.
If starting capability is jeopardized due to energy consumption, the
following warning appears in the MMI display:
Please start engine, otherwise system will switch off in 3
minutes .
The warning indicates that the system wi ll be turned off automati
cal ly after 3 minutes. If you wish to continue using the functions,
you have to start the engine .
With the engine running
Although e lectrica l energy is generated when the vehicle is being
driven, the battery can become discharged. This happens mostly
when little energy is being generated and a great deal consumed
and the battery's state of charge is not optimal.
To bring the energy balance back into equi librium , consumers
which require especia lly large amounts of energy are temporarily
cut back or switched off. Heating systems in particular require a
great deal of energy. If you notice, for example, that the heated
seats* or the heated rear window are not heating, they have been
temporarily cut back or switched off. These systems will be available
again as soon as the energy balance has been restored.
You wil l also notice that engine idle speed has been increased
s lightly . This is norma l and not a cause for concern . By increasing
engine idle speed the additiona l energy required is generated and
the battery is charged. •
Driver notification in the instrument cluster
display
If the battery's state of charge is not in the optimal range, this driver
notification appears in the instrument cluster display:

New brake pads
--
Remember that new brake pads do not have a full braking
effect during the first 250 miles (400 kilometers) after they
are installed .
New brake pads have to be "burnished in" before they have optimal
grab =>& .
During the break -in period, you should 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
New brake pads don't have the best stopping power and must be
"broken-in" during the initial 100 to 150 miles (150 to 200 kilome
ters) of normal city driving. You can compensate for this by
pressing the brake pedal more firmly . This also applies later when
new pads are installed.

Catalytic converter
It is very important that your emission control system
(catalytic converter) is functioning properly to ensure that
your vehicle is running in an environmentally sound
manner.
- Always use lead-free gasoline:=> page 303, "Fuel supply".
- Never run the tank down all the way to empty.
- Never put too much motor oil in your engine ==>
page 314,
"Adding engine oil 't=:;r\11
•
Never try to push- or tow-start your vehicle.
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 exclusive use of unleaded fuel is critically important for the life
of the catalytic converter and proper functioning of the engine.
& WARNING
• Do not park or operate the vehicle in areas where the hot
exhaust system may come in contact with dry grass, brush, fuel
spill or other material which can cause a fire .
• Do not apply additional undercoating or rustproofing on or
near the exhaust manifold, exhaust pipes, catalytic converter or
heat shields. During driving, the substance used for undercoating
could overheat and cause a fire .
0 Note
• Be aware that just one tank filling with leaded fuel will alr eady
seriously degrade the performance of the catalytic converter.
• Do not exceed the correct engine oil level=>
page 314.
• Do not drive until the fuel tank becomes completely empty. The
engine could misfire. Unburned fuel could also get into the exhaust
system and this could cause the catalytic converter to overheat.
• Do not turn off the ignition while the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fuel can reach the catalytic converter. This could result
in overheating of the converter, requiring its replacement .
• To assure efficient operation of the Emission Control System:
- Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty
& Maintenance
booklet. •

one half. Never drive faster than the posted speed limit and weather
conditions permit. •
Reducing unnecessary =citing
Even when your car is just idling it burns up fuel.
- Shut the eng ine off when you are not driving the vehicle .
- Do not warm up the vehicle by letting the engine run at
idle.
It makes sense to shut off the engine in traffic jams, when waiting
for trains to pass at rai lroad crossings , or at traffic lights that have
long waits on red. Turning the engine off for just 30 -40 seconds
saves more fuel than is burned starting the engine again .
It takes a long time for the engine to warm up fu lly when it is
running at idle. However, wear and noxious emissions are especially
high when the engine is warming up. So you should drive away as
soon as you start the engine and avoid running at high rpms while
the engine is still warming up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would
go unheeded. Extended idling also produces heat, which could result in overheating or other damage to the vehicle or other
property .•
Regu1ar ma1--.tenance
A badly tuned engine unnecessarily wastes a lot of fuel.
-Have your vehic le serviced at regular intervals .
By having your vehicle regularly serviced by an Audi dealer helps to
ensure that it runs properly and economically. The condition of your
vehic le not only affects its safety and abi lity to hold its value, it also
affects
fuel con sumpt ion.
C hec k your o il e ach time you fill your t ank.
The amount of oil used is related to engine load and speed.
It is norma l for the oil consumption of a new engine to reach its
lowest va lue after a certain mileage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly assess oil consumption .
This also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty
& Maintenance
booklet. Lack of proper ma intenance as well as improper use of the
vehic le wi ll impair the function of the emission control system and
cou ld lead to damage.
• Do not alter or remove any component of the Emission Control
System unless approved by the manufacturer.
• Do not alter or remove any device, such as heat shields,
switches, ignition wires, valves, which are designed to protect your
vehicle's Em ission Control System and other important vehicle
components .•
Fewer short tr ips
Fuel consumption will always be relatively high on short
trips.
- Try to avoid driving short dista nces wi th a cold engine. _,

use and are not an indication of material deterioration.
0 Note
• Never use chemical solvents (e.g. lighter fluid, turpentine),
waxes, shoe polish or similar products on Alcantara ® surfaces.
• To avoid damage, have stubborn stains removed by a commer
cial cleaning specialist.
• Do not use brushes, stiff sponges or similarly abrasive cleaning
aids .•
Safety belts
Only well-maintained safety belts work reliably when
needed.
- Keep belts clean.
- For cleaning, use a mild soap and water solution . Let
belts dry thoroughly and away from direct sunlight .
- Do not allow inertia reel safety belts to retract before
they are completely dry.
- Check the condition of your safety belts
regularly.
Heavily soiled safety belts may not retract properly.
& WARNING
Damaged safety belts can break in a crash.
• Anything that might damage your safety belts could mean that
you and your passengers would not be adequately protected in an
accident.
• Safety belt performance depends on correct installation. Never
remove belts from the vehicle to clean them.
& WARNING (continued)
• Do not use chemical cleaning agents, bleach or dyes. They have
corrosive properties which weaken the webbing.
• When cleaning your safety belts, inspect them for damage. If
you discover damage, see your Audi dealer.
• Always read and heed all WARNINGS and other information

Always switch off the ignition before cleaning the engine ~ &.
Plenum panel
Remove leaves from the plenum panel in front of the windshield
under the engine hood. This prevents the water drain holes from
becoming blocked, and it prevents debris from entering the vehicle
interior through the heating and ventilation ducts.
Corrosion protection
The engine compartment and transmission have been corrosion
protected at the factory.
Good anti -corrosion treatment is very important, particularly in the
winter. If the vehicle is frequently driven on salt treated roads, the
entire engine compartment and plenum panel should be thor

Engine cooling system
Coolant
The engine coolan t perf orms two func tions: it keeps t he
engine from overheating an d it protects the engine from
freezing in the winter.
The cooling system is sealed and general ly requires litt le attention.
The coo ling system has been fi lled at the factory with a permanent
coo lant which does not need to be changed. The coolant consists of
a mixture of water and the manufacturer's glycol -basedcoolant
additive G12+ + antifreeze with anti corrosion additives (50% for USA
models; 60% for Canadian mode ls) . This mixture both assures the
necessary frost protection and protects metal components in the
engine's cooling system from corrosion and scaling. It also raises
the boil ing point o f the coolant.
D o not reduce the concentration of the coo lant in the summer by
adding pla in water.
Th e proporti on of coolant additive must b e at
l e as t 50 % but not more than 60 %
to maintain antifreeze protection
and cooling efficiency . If the coolant frost protect ion is too low, the
coo lant could freeze and damage the vehicle heating and engine
coo ling system.
For year-round driving, antifreeze is added at the factory for temper
atures down to :
• -31 °F ( -35 °C) USA
• - 40 °F ( - 40 °C) Canada .
You can mix the G 12 + + coolant additive wit h other additives (G12 +
or G12). A lways check with your authorized Audi dealer .
