& WARNING
• The luggage compartment cover must never be installed
without being secured -this creates an accident hazard.
• Whenever driving, never place any hard or heavy objects on the
luggage compartment or allow pets to sit on the luggage compart­
ment cover . They could become a hazard to vehicle occupants in
the event of sudden braking or in an accident.
0 Note
Make sure that the heating wires in the rear lid do not get damaged
by objects scraping against them.
[ i ] Tips
• You can use the luggage compartment cover to store light
weight clothing but do not leave any heavy or sharp objects in the
pockets of the clothing.
• Remember that placing clothing on the luggage compartment
cover can block the driver's vision in the rear view mirror. This also
applies especially when you have to transport large objects.
• So that stale air can escape from the vehicle be sure not to cover
the ventilation slot between the rear lid and the luggage compart ­
ment cover installed. •

Climate controls
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recomme nd the following s ettings:
- Select and set a temperature between 64
°F (+22 °C) and
84 °F (+28 °C).
- Press the !AUTO
I button.
With this setting, you attain maximum comfort in the least amount
of time . Change this set ting, as desired, to mee t your pe rsonal
needs.
The climate controls are a combination of heating, venti lation and
cooling systems, which automatica lly reduce humidity and coo l the
air inside your vehic le .
The air temperature, air flow and air distribution are automatically
regu lated to achieve and maintain the desired passenger compart ­
ment temperature as quick ly as possible.
The system automatically compensates for changes in the outside
temperature and for the intensity of the sun light entering the
veh ic le. We recommend you use the
Automat ic mode=> page 101
for year -round comfort.
P lease note the following :
Turn on the air conditioner to reduce humidity in the vehic le. This
a lso prevent the window s from fogging up. When the outside temperature is high and the air is very humid,
c
ondensat ion from the evaporator may drip under the vehicle . T his
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 coola nt has war med u p sufficiently .
T he air conditioner temporarily sw itches off when you drive off from
a standstill using fu ll throttle to save engine power.
The comp ressor also swi tches off if the coolant temperatu re is to o
high so that the engine can be adequate ly cooled under extreme
lo ads .
Air pollutants filt er
The air po llutants fi lter (a combined partic le filter and activated
charcoal fi lter) reduces or eliminates outside air pollution (dust, or
p ollen) from en ter ing the vehic le .
The air po llutants fi lter must be changed at the intervals specified
in your Warranty
& Maintenance bo oklet, so that the ai r conditioner
can proper ly work.
I f you drive your vehicle in an area with high air pol lution, the filter
may need to be changed m ore freque ntly tha n specified in your
Audi Warranty
& Maintenance booklet. If in doubt, ask your autho­
r iz ed Aud i Service Adviso r fo r a dvice .
& WARNING
Redu ced vi sibility i s dangerou s and can cause accidents .
• For saf e driving it is very important that all window s be free of
ice , sno w and conden sation.
• Fully familiarize yourself with the proper use and fun ction of
the heating and ventil ation sy stem and especially how to defog
and defrost the windows. ...

& WARNING (continued)
• 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
off the air conditioner 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 On 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.
• 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 .
• A sensor in the grill provides the air-conditioning system contin­
uously with readings of current outside temperature . So that the air ­
conditioning can operate at maximum efficiency, the area below the
front license plate holder must not be covered .•

How the system works
The EDL operates automatically. It monitors the rotational speed of
the drive wheels on an axle with the help of the ABS sensors
=:,
page 194. If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground
on
one side),
the spinning wheel is braked, thereby transferring power
to the other drive wheel or wheels (all-wheel drivel. This is done up
to a speed of about 60 mph (100 km/h). Noises from the brake
system signal that wheel spin is being controlled.
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 16. •
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 194, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
torque 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 .
Activating
The ESP is automatically activated when the engine is started and it
performs a self -test . You can activate a deactivated ASR if required
by pressing the =:,
page 190, fig. 163 button . When it is activated,
the message
ESP/ASR on appears briefly in the display.
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=:,
page 190, fig . 163. With the ASR deactivated, .,

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
Until they develop the maximum "bite " for best stopping power,
the surfaces on new brake pads require some "breaking -in" during
the initial 100 to 150 miles (150 to 200 kilometers) of normal city
driving. You can compensate for this by pressing the brake pedal
more firmly . This applies whenever 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 219, "Fuel supply".
- Never run the tank down all the way to empty.
- Never put too much motor oil in your engine ==>
page 230,
"Adding engine oil 't=:;rl".
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 230.
• 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 authori
zed Audi
dea ler helps to ensure that it runs properly and economica lly. The
condition of your vehicle not only affects its safety and ability to
hold its value, it a lso affects
fu el con sumpti on.
C he ck your oil each 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 .
T his 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 Emiss ion 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. _,
