@ Tips
- The light sensor* for headlight control is
located in the rear view m irror mount.
You should therefore not apply any st ick­
ers to the windsh ield in this area in order
to prevent malfunctions or failures.

tion while the vehicle's lights are turned
on, a buzzer sounds as long as the driv­
er's door is open .
- In cool or damp weather, the ins ide of
the headlights, turn signals and tail lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clea r shor tly after
switching them on. This does not affect
the service life of the lighting.
- In the even t of a light sensor malfunc­
tion, the driver is no tified in the instru­
ment cluster disp lay¢

General recommen­
dations
Why is your seat adjustment so
important?
The safety belts and the airbag system can
only provide maximum protection if the front
seats are correctly adjusted.
There are various ways of adjusting the front
seats to provide safe and comfortable support
for the driver and the front passenger. Adjust
you r seat prope rly so that :
- you can easily and quickly reach all the
switches and controls in the instrument
panel
-your body is properly supported thus reduc­
ing physical stress and fatigue
- the safety be lts and airbag system can offer
maximum protection ¢
page 144.
In the following sections, you will see exactly
how you can best adjust your seats .
There are special regulations and instructions
for installing a child safety seat on the front
passenger's seat. Always follow the informa­
tion regarding child safety provided in
¢ page 165, Child Safety.
WARNING
Refer to¢ page 126, Driving Safely for
important information, tips, suggestions
and warnings that you should read and fol­
low for your own safety and the safety of
your passengers.
A WARNING
, -
Incorrect seating position of the driver and
all other passengers can result in serious
personal injury .
- Always keep your feet on the floor when
the vehicle is in motion -never put your
feet on top of the instrument panel, out of the w indow or on top of the seat cush­
ion. This applies especially to the passen- gers
. If your seating position is incorrect,
you increase the risk of injury in the case
of sudden braking or an accident. If the
airbag inflates and the seating position is incorrect, this could result in personal
injury or even death.
- It is important for both the driver and front passenger to keep a distance of at
least 10 inches (25 cm) between them­
selves and the steering wheel and/or in­
strument panel.
If you're sitting any
closer than this, the airbag system can­
not protect you properly. In addition, the
front seats and head restraints must be
adjusted to your body height so that they
can give you maximum protection.
- Always try to keep as much distance as
possible between yourself and the steer­
ing wheel or instrument panel.
- Do not adjust the driver's or front pas­
senger 's seat while the vehicle is moving.
Your seat may move unexpectedly, caus­
ing sudden loss of veh icle control and
personal injury. If you adjust your seat
while the veh icle is moving, you are out
of posit ion.
Driver's seat
The correct seat position is important for safe
and relaxed driving .
We recommend that you adjust the driver's
seat in the following manner :
.. Adjust the seat in fore and aft direction so
that you can easily push the pedals to the
floor wh ile keeping your knees slightly bent
o &. in Why is your seat adjustment so im ­
portant? on page
60 .
.,. Adjust the seatback so that when you sit
w ith your back against the seatback , you can
still grasp the top of the steering wheel.
.. Applies to vehicles with adjustable head re­
straints: Adjust the head restraint so the up­
per edge is as even as possible with the top
of your head. If that is not possible, try to
adjust the head restraint so that it is as .,.

78 Warm and cold
Warm and cold Climate controls
Description
The climate control system warms, cools and
adds humidity to the air in the vehicle interior.
It is the most effect ive when the windows and
sunroof are closed . If there is a build-up of
heat inside the vehicle, ventilation can help to
speed up the cooling process.
I n all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensat ion from the cooling system can
drip and form a puddle of water under the ve­
hicle. This is normal and does not mean there
is a leak.
Pollutant filter
The pollutant filter removes pollutants s uch
as dust and pollen from the air.
The air pollutants filter must be changed at
the intervals spec ified in you r Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work.
If you drive your vehicle in an area with h igh
a ir po llution, the fi lter may need to be
changed more frequent ly than specified in
your Aud i Wa rranty
& Ma intenance booklet. If
in doubt, ask your authorized Audi Service Ad ­
visor for advice .
Key coded settings
The climate control settings are automat ically
stored and assigned to the remote control key
that is in use.
A 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 con­
densation.
- Comp letely 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 freez ing weather unt il you
have warmed the windshield first, using
the heating and ventilation system. The
washer solution may freeze on the wind­ shie ld and reduce visib ility.
(D Note
- If you suspect that the air conditioner
has been damaged, switch the system
off to avoid further damage and have it
inspected by a qualified dealership.
- Repairs to the Audi air conditioner re­
quire special technical know ledge and
special tools. Contact an authorized Aud i
dea ler fo r assistance.
@ For the sake of the environment
By reducing the amount of fuel you use,
you also reduce the amount of pollutants
emitted into the air.
(D Tips
-Keep the air intake s lots (in fro nt of the
w indshield) free from ice, snow and de ­
bris in order to maintain the proper func­
tion of the climate control system.
- T he energy management system may
switch the seat heating* or rear window
defroster off temporarily . These systems
are available again as soon as the energy
balance has been restored.
- Air escapes through vents under the rear
window. When placing items of clothing
on the luggage compartment cover, en­
sure that the openings are not covered.
