70 Warm and cold
Warm and cold Climate control system
Description
Different systems could be installed.
- manual climate control system* or
- automatic climate control system*
The
climate control system* cools and re­
moves humidity from the air in the vehicle in­
terior. It is the most effective when the win­
dows and power top are closed. If there is a
build-up of heat inside the vehicle, ventila tion
can help to speed up the cooling process. Be­
cause of this, the windows can be opened
from outside .
~ page 39, Convenience open­
ing/closing
Pollutant filter
The pollutant filter removes pollutants such
as dust and pollen from the air .
Key recognition
You can store various settings for the manual
and automatic
climate control system* and
assign them to the key being used .
A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep a ll windows free
of ice, snow and fog.
- Become familiar as quickly as possible
with the correct use and function of the
climate control system, especially with
the defrosting and defogging function .
- When the temperature is below freezing,
only use the windsh ield washer system
after the w indshield has been warmed by the cl
imate control system . The washer
fluid could freeze on the windshield and
impair visibility.
(D Note
- If you suspect that the climate control
system is damaged, switch the system
off to prevent further damage and have
it checked by an authorized Audi dealer
or authorized Audi Service Facility.
- Repairs to the Audi climate control sys­
tem require special technical knowledge
and special tools. See an authorized Audi
dealer or authorized Audi Serv ice Facility .
® For the sake of the environment
Reducing the amount of fuel used also re­
duces the amount of pollutants that enter
the air.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the
w indows from fogging over, the air in­
take in front of the windshield must be
free of ice, snow or leaves.
- Condensation from the cooling system*
can drip and form a puddle of water un­
der the vehicle. This is normal and does
not mean there is a leak.
- T he energy management system may
switch the seat heating* or rear window
defroster off temporari Ly. These systems
are available again as soon as the energy
balance has been restored.
- The flows through the vents under the
rear window. Make sure the openings are
not covered when placing clothing on the
luggage compartment cover.

turned on, it will not turn on again auto­
ma tically if more than

Adjusting the steering wheel position
The steering wheel position is fully adjustable
up and down and forward and bock .

.. Tilt the lever ¢ fig. 78 downward ¢ &_.
.. Bring the steering wheel into the desired
position .
.. Push the lever against the steering column
until it latches .
_& WARNING
Incorrect use of the steer ing whee l adjust­
ment and an incorrect seating position can
cause serious injuries.
- Only adjust the steering column when
the vehicle is stationary so that you do
not Lose control of the vehicle.
- Adjust the driver's seat or steering wheel
so that there is at least 10 inches
(25 cm) distance between your chest and
the steering wheel
r=.> page 12 7,
fig. 123. If you do not maintain this dis­
tance, the airbag system will not be able
to provide its full protection
<=> page 127, fig. 123.
- If your physical characteristics prevent
you from sitting at least 10 inches
(25 cm) or more away from the steering
wheel, see if your authorized Audi dealer or authorized Audi Service Fac ility can
provide adapters that will help.
- If your face is level with the steering
wheel, the airbag does not provide as much protection during a collision. Al­
ways make sure that the steering wheel
is level with your chest .
- Always hold the steering wheel with your
hands in the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of injury if the
airbag deploys.
- Never hold the steering wheel in the 12
o'clock position or with both hands on
the rim or the center of the steering
wheel. Holding the steering wheel incor­
rectly significantly increases the r isk of
injury to the hands, arms and head if the
airbag deploys.
