seasons .
Switching on AUTO
- Select temperature between 64 °F (+18 °C) and 84 °F
(+29 °C).
Press [AUTO ]
=> page 126, fig. 137.
AUTO only works when you set the inside temperature between
64 °F (18 °C) and 84 °F (29 °C). If you select a temperature below
64 °F (18 °C),
LO will appear in the display. If you select a tempera­
ture above 84 °F (29 °C),
HI will appear in the display.
The system automatically compensates for changes in outside
temperature and for the intensity of the sunlight.
[ i] Tips
By keeping the (AUTO I button on the driver's side pressed for
severa l seconds, the temperature of the passenger's side can be
synchronized to the temperature of the driver's side or vice versa.
The new temperature setting will be shown in the display .•

In the air recirculation mode , the air in the passenger compartment
is recirculated to prevent exhaust fumes and other pollution from
entering the vehicle. We recommend that you use the manual air recirculation under the following conditions:
• when driving through tunnels
• in a tra ffic jam.
& WARNING
Do not use this setting for extended periods of time . The windows
could fog up since no fresh air can enter the vehicle.
If the
windows fog up, press the air recirculation button again immedi­ ately to switch off the air recirculation function or select defrost. •
ECON [ECON]
Using ECON helps save fuel
- Press [ECON] to activate ~ page 126, fig. 137.
Press [ECON] again or press [AUTO] to switch off.
In ECON mode the air conditioner is shut off and heating and venti ­
lation are automatically controlled . "ECON" translates "Economy"
since driving with the air conditioning compressor disengaged
improves your mileage noticeably.
When operating in ECON mode make sure the temperature inside
the vehicle is not lower than the outside temperature. The air is
nei ther cooled nor dehumidified, so there is a risk that the windows
can fog up .•
Switching the air conditioning on and off [ OFF]

exhaust fumes in the outside air, the contro l unit wil l either pass the
incom ing a ir throug h the pol lution filter, or automat ical ly switch on
the air recirculation.
The air conditioning system wi ll automatically switch on the air
recirculation if it senses that the outside air is very po lluted . At the
same time, it will not allow any outside air to enter the vehic le until
the air quality has improved .

footwel ls.
[ i ] Tip s
• When defrosting/defogging the windows, air flows from outlets
G),@ and G) . To defrost or defog the windows as rapidly as
possible , air outlets
G) should be opened fully with the adjuster
whee ls .
• When the air conditioner is working, cooled air will flow primarily
from
ou tlets @, G) and @. To assure adequa te cooling, out lets G)
and © should never be completely closed .•

Technical data

Warm and cold
----------------
The rear window defogger works only when the ignition is switched
on. The light in the switch will illuminate when the defogger is on .
When the outside temperature is warmer than 32 °F (O °Cl , the rear
window defogger switches off automatically after about ten minutes.
'£> F o r the sake of the environment
Switch off the defogger when the rear window is clear . When you
save e lectricity, you save fuel. •
Using the climate controls economically
Using the climate controls prudently can help save fuel .
When you use the air conditioner, engine power is reduced
and fuel consumption increases . To save fuel, you should
use the air conditioner only when necessary . Also please
note the following points:
-If you want to save fuel, activate ECON.
-If you are goi ng to drive w ith the windows open, use
ECON.
'£> For th e sake of the environment
By reducing the amount of fue l you use , you also reduce the amount
of pollutants emitted into the air. •
Key coded settings
When the ignition is switched on, the air conditioner
settings are automatically assigned to the key being used.
The air conditioner settings selected are automatically stored and
assigned to the key being used. When the vehicle is started, the air
conditioner automatically selects the settings assigned to that key.
This way every dr iver will ma intain his/her own personal settings
and does not have to reset them manually .
[ i ] Tip s
If a different driver uses your key and changes the air conditioner
set tings, the latest adjustments will erase and replace the settings
you have stored. •

On the road
Steering
Adjusting the steering wheel column
The height and reach of the steering wheel can be
adjusted.
Fig . 142 Lever under
the steering column
First, adjust the driver's seat correctly.
- Push the
lever => fig. 142 -Arrow- =>& .
Move the steering wheel to the desired position.
- Push the lever against the steering column unt il it locks.
There must be at least 10 inches (25 cm) between your breastbone
and the center of the steering wheel. If you cannot sit more than 10
inches (25 cm) from the steering wheel,
we recommend that you
investigate whether adaptive equipment is available to help you
reach the pedals and increase your seating distance from the
steering wheel. For detailed information on how to adjust the driver's seat, see
=> page 97, "Power seat adjustment"
.
& WARNING
Improper use of steering wheel adjustment and improper seating
position can cause serious personal injury .
• Adjust the steering wheel column only when the vehicle is not
moving to prevent loss of vehicle control.
• Always make sure that the adjustment lever is securely pushed
up so that the position of the steering wheel cannot be changed
unintentionally when the vehicle is moving.
• Adjust the driver's seat or steering wheel so that there is a
minimum of 10 inches (25 cm) between your breastbone and the
steering
wheel ~ page 168, fig. 162. If you cannot maintain this
minimum distance the airbag system cannot protect you properly.
• If physical limitations prevent you from sitting 10 inches (25
cm) or more from the steering wheel, check with your authorized
Audi dealer to see if adaptive equipment is available.
• Pointing the steering wheel toward your face decreases the
ability of the supplemental driver's airbag to protect you in an
accident. Always make sure that the steering wheel is pointed
towards your chest .
• Always hold the steering wheel on the outside of the steering
wheel rim with your hands at the 9 o'clock and 3 o'clock positions
to help reduce the risk of personal injury if the driver's airbag inflates.
• Never hold the steering wheel at the 12 o'clock position or with
your hands at other positions 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
driver's airbag inflates.
