l= I Switching recirculation mode on and
off
I n recirculation mode, the air inside the vehi­
cle is circu lated and filtered. This prevents the
unfiltered air outside the vehicle from enter­
ing the vehicle interior. We recommend
switching recirculation mode on when driving
through a tunnel or when sitt ing in traffic

Automatic climate control system
We recommend pressing the IAU TO I button

The automatic climate control system auto­
matically maintains a temperature once it has
been set. The temperature of the air from the
vents, the blower speed, and air distr ibution
are also automatically adjusted . In all heat ing
mode funct ions except
defrost, the blower
only switches to a higher speed once the en- Recirculation
mode is switched off in the de­
frost setting ~-
.&_ WARNING

You shou ld not use the recirculation mode
for an extended period s ince no fresh air is
drawn in. With the air-conditioning*
switched off, the w indows can fog up,
which increases the risk of an acc ident.

IA/CI Switching the cooling mode on and
off
T he cooling system is turned on and off with
the
IA/Cl button . The air is not coo led and hu­
midity is not removed when cooling mode is
switched off . This can cause fog on the win­
dows. Cooling mode switches off automatical­
ly when the outside temperature is below
zero .

The seat heating switches automatically from
setting 3 to setting 2 after 10 minutes.
When seat heat ing should not be
sw it ch ed on
Do not turn the seat heating on under the fol­
l owing circumstances:
- T he seat is unocc upied.
- The seat is covered w ith a seat cover .
- The seat is covered w ith a child seat.
- The seat is damp or wet.
A WARNING
Individua ls with reduced sensitivity to pain
or temperature could develop burns when
using the seat heating function. To reduce
the risk of injury, these individuals should
no t use sea t heat ing.
{[) Note
To avo id damage to the heating elements
in the seats, do not kneel on the seats o r
place heavy loads on a small area of the
seat.
{D) Tips
- The setting for the seat heating on the
drive r's side is assigned to the key that is

Steering
Adjusting the steering wheel position
The steering wheel position is fully adjustable
up and down and forward and bock .
Fig. 64 Steering column: steering column adjustment
lever
.. Tilt the lever¢ fig. 64 downward ¢ &_.
.. Bring the steering wheel into the desired
position .
.. Push the lever against the steering column
until it latches .
_& WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury.
- Adjust the steering wheel column only
when the veh icle is not moving to pre­
vent loss of vehicle control.
- Adjust the driver's seat or steering wheel
so that there is a min imum of 10 inches
(25 cm) between your chest and the
steering wheel¢
page 122, fig. 109 . If
you cannot maintain this minimum dis­
tance, the airbag system cannot protect
you properly.
- If phys ica l limitations prevent you from
sitting 10 inches (25 cm) or more from
the steering wheel, check w ith your au­
thorized Aud i dealer to see if adaptive
equipment is availab le .
- If the steering wheel is alig ned with your
face, the supplemental driver's airbag cannot p rovid e as much protectio n in an
accident. Always make sure that the steer
ing whee l is aligned with your
chest.
- Always hold the steering wheel with your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of personal injury
if the driver's airbag deploys.
- Never hold the steering wheel at the 12
o'clock position or with your hands inside
the steering wheel rim or on the steering
wheel hub. Holding the steering wheel
the wrong way can cause serious injuries
to the hands, arms and head if the driv­
er's airbag deploys.

D rive to an autho rized Audi dea ler or qualified
repair facility immediately to have the ma l­
function corrected.
A WARNING
- Never allow the engine to run in confined
spaces -there is a r isk of asphyxiation.
Driving 71
- Never remove the ignition key from the
ignit ion lock while the vehicle is mov ing.
Otherwise the steering lock will engage
and you will not be able to steer the vehi­
cle.
- The brake booster and power steering
only work when the eng ine is running. If
the engine is off, you have to use more
force when stee ring or braking. Because
you cannot steer and bra ke as you usual­
ly would, this could lead to crashes and
serious inju ries .
- Always take the vehicle key with you
when leaving the vehicle, even for a
short period of time . This applies partic­
ular ly when c hildren remain in the vehi­
cle. Otherwise the children could start
the engine or operate electrical equip­
ment such as power windows.
(D Note
- Avoid high engine speed, full th rottle,
and heavy engine load as long as the en­
gine has not reached operating tempera­
ture yet. You could damage the engine.
- The engine cannot be started by pushing or towing the vehicle.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
reduces unnecessary emissions.
(D Tips
-If it is difficult to turn the key to position
(D, turn the steering wheel back and
forth slightly to release the steer ing
wheel lock.
-After starting a cold engine, there may be a brief period of increased no ise be­
cause the oil pressure must first build up
in the hydraulic valve adjusters. This is
normal and not a cause for concern.
- If the battery is disconnected and recon­
nected, you have to hold t he ignition key
in posit ion
(D for five seconds fo r the en-
gine to start.

park your vehicle with the selector lever
in P. Otherwise, the vehicle could inad­
vertently roll away.
- After the engine has been switched off,
the radiator fan can continue to run for
up to 10 minutes -even with the ignition
switched off.
It can also switch on again
after some time if the coolant tempera­
ture rises as the result of a heat buildup
or if the engine is hot and the engine
compartment is additionally heated by
the sun's rays .
(D Note
-If the engine has been under heavy load
for an extended period of time, heat builds up in the engine compartment af­
ter the engine is switched off -there is a
risk of damaging the @ngin@ . For this
reason, let the engine run for at idle for
approximately two minutes before shut ­
ting it off.
