System AIR
BAG
The ind icator light for the airbag and belt
tensioner system must come on when
the ignition is switched on, and go out after
a few seconds. If the light does not go out,
or if it comes on while you are driving, this
ind icates a fault in the airbag I belt tensioner
syste m.
If the indicator light does not come on when
the ignition is switched on, this also indi­
cates a system malfunction. If any of these
conditions occur, have the air bag system in­
spected immediately by your authorized
Audi Dealer.

�W ARNING
• For clear visibility and safe driv­
ing, it is extremely important that
you follow the operating instruc­
tions on the proper use and func­
tion of the ventilation/heating, de­
fogg ing{defr osting and air condi­
tioning system in this manual. If in
doubt, consult your authorized
Audi Dealer.
• Good visibility comas with
clean windows free of fog, con­
densation and frost.
• Maximum heating output and
fast defro sting will occur only af­
ter the engine has reached operat­
ing temperature. Wait until you
have good visibility before moving
your vehicle.
16 2 The
air conditioner is fully auto­
matic, and is designed to maintain a com­
fortable and uniform climate inside the ve­
hicle .
The temperature of the air supplied to the in­
terior, the fan speed, air distribution and vol­
ume of air delivery are regulated automati­
cally.
This automatic climate control program can
also be adjusted manually by the driver and
the front passenger.
The illustration on the next page shows the
controls for the driver and front passenger
in the center console. The left display indi­
cates the temperature selected for the driv­
er's side and the right display the tempera­
ture selected for the front passenger's side.
The temperature is selected by pressing the
"+" or "-" buttons beneath the respective
displays. Recommended
standard setting for
all-year operation:
After switching on the ignition
• Select a temperature of
75 oF (23°C) and
• Press AUTO button.
With this setting, you attain maximum com­
fort in the least amount of time.
You only need to change this setting to
meet your personal needs.

CONTROLS AND
EQUIPMENT---------------------
C... -Air recirculation
In the air recirculation mode, the supply of
outside air is blocked and the air in the pas­
senger compartment is recirculated. This
helps to prevent pollutant-conta ining out­
side air from entering the passenger
compartment. It is best not to use this set­
ting for exte nded periods of time.
If the windows begin to fog or ice
up, select the ® program setting as
soon as possible.
�W ARNING
• You will not receive any fresh
outside air when air recirculation
is on. Do not use this setting over
long periods of time because stale
air contributes to fatigue and re­
duced driver alertness.
• If the windows fog up, press the
air recirculation button again im­
mediately to switch off the air re­
circulation function or select de­
frost.
16 4 ECON -
Economy
The air conditioner compressor can be
turned off to save fuel. However, the com­
fort level that the system can achieve in this
mode limited.
If the interior of the vehicle gets too hot, or
if the windows begin to fog or ice up, press
the ECON button again to tum the compres­
sor on again and switch back to AUTO .
OFF -Switching air conditioner oft
The air conditioner can be switched off by
pressing the button briefly. This cuts off the
supply of air from the outside.
To reactivate the air conditioner,
press the AUTO button or one of the blower,
temperature or air distribution selector but­
tons, or press OFF again.
It is not normally necessary to switch off the
air condition er.
- + Fan speed
The automatically selected fan speed (vol­
ume of air delivery) can be reduced or in­
creased manually by operati ng these but­
tons. The selected fan speed is shown by a
segment display above the buttons. 4iiJ

AND EQUIP MENT
Air outlets
Depending on the operating mode se­
lected, the air flow to the outlets is con­
trolled either automatically or man ually.
The illust ration shows the air outlets in and
around the dashboard.
The outlets deliver either heated or un­
heated fresh air, or cooled air. I

5 - Footw all outlets Outlets
2, 3 and 4 can be opened or
closed separately with the respective
thumbwheel next to the outlets.
The direction of air delivery from these
outlets can be adjusted horizontally and
vert ically. The upper outlets (2) are not ad­
justable.
Note
When the air conditioner is cooling the ve­
hicle interior, the cool air mainly emerges
from outlets 3 and 4. To ensure adequate
cooling, these outlets should therefore nev­
er be closed completely.
165

CONT
ROLS AND EQUIPMENT
The above illustration shows the outlets at
the rear of the center console.
Air is directed to these outlets automati­
cally.
The heater outlets for the rear footwall are
located under the front seats. They are con­
trolled together with outlet 5.
16 6 Solar
roof*
On models with a solar sliding roof, if the ve­
hicle is parked in sufficiently strong sunlight
and the ignition has been turned off, the
blower automatically switches to the solar­
powered mode. The blower motor runs on
solar energy, keeping the vehicle's interior
supplied with fresh air.
For optimum air delivery the center (4) and
the side dashboard vents (3) should be
opened.
The solar -powered fan only works when the
sliding roof is closed or raised open at the
rear.
If the ventilation system happens to be set
to the recirculate mode, the climate control
system automatically switches to the fresh
air mode. Key
coding
To achie ve maximum comfort levels, the
current manual settings for the air condi­
tioning system are automatically saved.
For example, if the air conditioning settings
were changed when someone else used
your car, the air condition system will auto­
matically be reset to the settings that match
your key when you turn on the ignition
again.
This assumes that the previous driver used
a key other than yours. If the previous driver
used your key, his or her new settings
would be assigned to your key.
If a number of persons use the vehicle, then
if possible, each should use a different key.
In this way, your personal air conditioning
set ting will be restored automatically.

General notes
• Vehicle heating is depend upon tne tem­
perature of the engine coolant -therefore,
your vehicle interior will warm uponly when
the engine has reached its operating tem­
perature.
When the ambient temperature is too low,
the fan only switches to high speed modes
when the coolant has reached a sufficiently
high temperature, or when the ® button
has been depressed.
• Keeping the air intake slots in front of the
windshield free from ice, snow and debris
helps to make sure that the climate control
system will work properly.
• When the air conditioner compressor is
on it reduces both the temperature and the
humid ity of the air inside the vehicle. This
prevents the windows from fogging up.
• The air conditioner works best with the
windows and power roof* closed. •
If the inside temperature is very high af­
ter the vehicle has been parked in the sun,
open windows and allow the hot air to es­
cape before switching on the air condi­
tioner.
• The dust and pollen filter will prevent
dust and pollen etc. in the outside air from
entering the car. Switch to air recirculation
to prevent unpleasant fumes from entering
the vehicle.
If water drips under the
vehicle ...
At high outside temperatures and humidity,
condensation may drip from the evaporator.
This is normal and does not indicate a leak.
If the airflow is not cool ...
• At low ambient temperatures the air con­
ditioner compressor switches off automati­
cally. The compressor cannot be switc hed
on again in this case, even by pressing the
AUTO button. •
The air conditioner may switch itself off
temporarily to ensure sufficient engine
cooling when the engine is running at full
load.
The air conditioner will also be switched off
temporarily in the kick-down function. See
page 109.
• Check the air conditioning fuse on the
fuse p imel -see page 27 4. Have it replaced,
if necessary.
• If you suspect that the air conditioner is
damaged, for instance after an accident,
switch to the ECON and have the system
examined immediately for leaks or other
damage.

CONTROLS AND
EQUIPMENT--------------------
Maintenance
• For maximum efficiency of the air condi­
tioner the dust and pollen filter elements
must 'be replaced at the intervals indicated
in the Maintenance Schedule.
• The condenser must be checked regu­
larly to make sure it is clean. If it becomes
obstructed by dirt or insects, spray 1t clear
with water.
• Repairs to the Audi air condition­
ing system require specialized
knowledge and special tools.
If the system is not functioning
properly, contact your Audi Dealer.
16 8 Power roof*
The roof will slide open or tilt up at the rear
as required. When the ignition is on it can be
opened and closed by turning the rota�
control next to the interior light. The roof 1s
tilted open or closed by pressing or pulling
the control -see illustration.
When turning the ignition off, however, the
sunr oof can still be operated as long as the
driver's and front passenger's door are
closed. When either door is opened, sliding
roof operation will be deactivated .
Always close the roof completely if you are
going to park your vehicle and leave. �W
ARNING
Be careful when closing the power
roof 1 tilt roof. Not paying atten­
tion could cause you or others to
be caught and injured as the roof
closes. To help avoid injuries
caused by closing the roof, always
take your key whenever you leave
your vehicle.

Emergency closing
If you cannot close the roof with the electric
switch, you can still close the roof manually
using a crank (see right illustr ation). The
crank is located behind the fuse cover (see
page 274).
In order to access the power roof motor, re­
move the interior light (lens and housing) as
follows:
• Place the flat side of the screwdriver
found in the vehicle tool kit on the rear side
of the lens as shown in the illustration and
carefu lly pry the lens downward.
17 0 •
Then insert the screwdriver into the gap
between the light housing and the frame in
the rear on the side and carefully pry out the
housing.
To close the roof, press the manual
crank (1) into the hex socket (2) until it en­
gages. Keep pressing down and turn the
crank.
Reinst all the light housing and lens in the
reverse order.
Have the problem corrected by your autho­
rized Audi dealer. Power
roof with solar panel*
The solar panel is operated in the same way
as the power roof. The roof's solar cells sup­
ply energy for the air conditioner blower.
See page 166.
The interior trim is fixed to the solar panel
cannot be opened and closed separately.

VEHICLE OPERA
TION-----------------------
Operate your vehicle safely
The condition of the vehicle is es­
sential for driving safety.
Therefore, always be sure to observe the
following points before you drive off:
• Check lights and turn signals.
• Check fuel level.
• Adjust the mirrors.
• Make sure that all lights and all
windows are clean.
• Make sure the air Intake slot be­
tween the engine hood and the
windshield is free of leaves, snow
and ice.
• Check warning and indicator
lights when starting the engine.
For driving safety, always follow the speci­
fied maintenance intervals in your Mainte­
nance booklet -especially for changing
the brake fluid, see page 242.
Yo ur personal driving style and your
attitude affect driving safety to a
very great extent.
19 4 Therefore,
for your own safety:
• Wear your safety belts and wear
them properly, even if you're just
driving in the city or to the corner
store -see page 14.
• Make sure that all passengers are
wearing their safety belts properly,
even those sitting in the rear -
see page 14.
Passengers not wearing safety belts endan­
ger not only themselves in case of an acci­
dent, but also the driver and other passen­
gers.
• Make sure that children always sit
on the rear seat properly restrained
by a res traint system appropriate
for their size and age.
• Never transport a child in a rear­
facing child or infant seat on the
front passenger seat.
• Adjust your seat so that you can
easily reach all controls as far away
from the airbag as possible but no
closer than 10 in. (25 em) -
see page 76. •
The seating position is very im­
portant for the airbag performance
- see page 29.
• Always adjust the head restra ints
to the correct height.
For maximum protection, the upper edge of
the head restraints should be at least at
eye level, or higher .
• Always make sure that the move­
ment of the pedals is not restricted
In any way-see page 102.
• Store luggage and light items
properly
in the luggage compartment ­
see page 88.
of the roof - see page 191.
• If you drink, do not drive.
The use of alcohol, drugs and certain medi­
cations will seriously impair perception,
reactions and driving ability, and substan­
tially increase the risk of an accident and
personal injury.
