In the air recirculation mode, the air in the passenger compartment
is recirculated and filtered 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 traffic jam .

r e ar window defo gger
Press the (ffiJ switch to turn the rear wi ndow defogger on
and off =:> fig . 11 6.
The rear window defogger works only when the engine is running.
The light in the switch will illuminate when the defogger is on.
The rear window defogger is switched automatically after 10 to 20 minutes, depending on the outs ide temperature .
At very low outside temperatures, the rear window defogger can
switched on continuously by pushing the
Qw button for more than 2
seconds. This remains stored until the ignition is switched off . A
rear window defogger that was switched on also remains stored for
15 minutes after the ignition is switched off.
If the engine is restarted within these 15 minutes, the rear window
defogger is activated for 10 to 20 minutes, depending on outside
temperature. With a vehicle that is parked for a short time, the rear
window defogger does not need to be manually activated again.
<£> For th e sake of th e environm ent
Turn the defogger off when the rear window is clear . When you save
electricity, you save fuel. •

The basic settings for the air conditioning can only be ma de
with MM I turned on.
Press the !SETUP] button in the controls to access the
menu.
Select the desired function using the control knob (driver
or passenger) in t he air condi tioning contro ls .
The fol lowing functions can be selected:
• ECON =>

• Auto recirc . => page 120
• Synchron . => page 120
• Center air vent=> page 121
• Solar operation*=> page 121 •
ECON
The ECON mode helps to save fuel.
The air conditioning is turned off in ECON mode. "ECON" means
"Economy" . By switching off the air conditioning (compressor), you
save fuel.
Please note that vehic le interior temperature cannot be lower than
the outs ide temperature in the ECON mode . The air is not cooled or
dehumidified.
If the vehic le interior becomes too hot or if the windows fog up,
ECON mode should be turned off . As soon as the !AUTO
I button in
the air conditioning controls is p ressed, the system automatically
leaves the ECON mode, and the air conditioning compressor is
turned on again .•
Automatic recirculation mode
An air quality sensor detects incre ased concentratio ns of
pollutants in the outside air and aut omatically switches
to recirculation mode.
We recommend that you always keep automatic air recirculation ON
to prevent polluted outside air from entering the vehicle interior .
I f the
air qualit y sensor located in the air conditioning system
detects po lluted outside air, the sensor decides whether the air
pol lution can be reduced by the factory -installed po llutant filter or
whe ther it is necessary to swi tch to air recirculatio n. With heavy
concentrations of pol lutants, the air conditioning system is
sw itched automatically to rec irculation mode and the supp ly of
outside air is blocked . As soon as the concentration of pollutants in
the outside a ir drops, fresh air is supp lied to the vehic le inte rior
aga in.
I n the event that the windows fog up during automatic air recircu la ­
t ion, you must press the® button immed iately.
Under certain operating conditions , automatic air recircu lation is
sw itched off automatically. With outside temperatures be low about
+10 °C , automatic air recirculation is limited to 30 seconds. With
outside temperatures below about -1 °C and in the ECO N mode,
automatic air recirculation is limited to 15 seconds .•
Synchronization
One climate control se tting f or all seats.
With synchronization active, the driver 's or the passenger's settings
are adopted for the other seats . Al l the other settings that were
made are trans ferred to the other seats. This includes all the c limate
control settings right down to the heated seats.
I f a differen t setting is selected at a "synchronized seat", synchroni ­
z ation is cancelled .•

standards. Therefore, vehicles built for the U.S .A. and Canada differ
from vehicles sold in other countries.
If you plan to take your vehicle outside the continental limits of the
United States or Canada, there is the possibility that
• unleaded fuels for vehicles with catalytic converter may not be
available;
• fuel may have a considerably lower octane rating. Improper fuel
may cause engine damage;
• service may be inadequate due to lack of proper service facilities,
tools or testing equipment;
• replacement parts may not be readily available .
• Navigation systems for vehicles built for the U.S.A. and Canada
will not necessarily work in Europe , and may not work in other coun­
tries outside of North America.
0 Note
Audi cannot be responsible for mechanical damage that could
result from inadequate fuel , service or parts availability .•

Maintenance
General
Your vehicle has been designed to help keep maintenance require­
ments to a minimum. However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle 's safety, economy and
reliability. For detailed vehicle maintenance consult your Mainte­
nance & Warranty booklet .
Under difficult operating conditions, for example at extremely low
outside temperatures, in very dusty regions, when towing a trailer
very frequently, etc., some service work should be performed
between the intervals specified. This applies particularly to:
• oil changes , and
• cleaning or replacing the air filter.
~ For the sake of the environment
By regularly maintaining your vehicle, you help make sure that emis ­
sion standards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fuel injection and
emission control systems, and the generally increasing technical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carried out by vehicle
owners. Also, safety and environmental concerns place very strict
limits on the nature of repairs and adjustments to engine and trans­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing devices and other equipment available to specially trained .,_
