Climate controls
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the fo llowing settings:
- Select and set a temperature between 71 °F (+22 °C) and
84 °F (+29 °C).
- Press the [AUTO
I button.
With this setting, you attain maximum comfort in the least amount
of time . C hange this sett ing, as des ired, to meet your personal
needs .
The climate contro ls are a combination of heating, ventilation and
cool ing systems, which automatica lly reduce humidity and coo l the
air inside your vehicle .
The air temperature, air flow and air distribution are automatically
regu lated to achieve and maintain the desired passenger compart ­
ment temperatu re as quickly as possible.
The system automatically compensates for changes in the outside
temperature and for the intensity of the sunlight entering the
veh ic le. We recommend you use the
Automati c mode=> page 127
for year-round comfort.
Please note the follow ing :
Turn on the air conditioner to reduce hum idity in the veh ic le. This
a lso prevent the windows from fogging up.
Controls and equip ­
ment
When the outside temperature is high and the air is very humid,
c o ndensat ion from the evaporator may drip under the vehicle. This
is normal and does not ind icate a leak.
If the outside temperature is low, the fan norma lly on ly switches to
a higher speed once the engine coolant has warmed up suff iciently .
The air conditioner temporarily switches off when you drive off from a standstill using ful l throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high so that the engine can be adequate ly cooled under extreme
loads .
Air p ollut ants filt er
The air po llutants fi lter (a combined part ic le filter and activated
charcoal filter) reduces or e liminates outside air pol lution (dust, or
pollen) from enter ing the vehic le .
The air po llutants filter must be changed at the intervals specified
in you r Maintenance
& Wa rranty booklet, so that the air cond itioner
can proper ly work.
If you drive your vehic le in an area with high air pol lution, the filter
may need to be changed more frequently than speci fied in your
Audi Maintenance
& Warranty book let. If in doubt, ask your autho­
ri zed Aud i Service Adv isor fo r advice .
& WARNING
Reduced vi sibility i s da ng erou s and can cause accident s.
• For safe driving it is very important that all windows be free of
ice , snow and cond ensa tion .
• Fully familiarize yourself with the proper us e and function of
the heating and ventilation sy stem and e speci ally how to defog
and defrost the window s.

Air recircul ation [~]
The air recirculation prevents exhaust fumes or other
pollution from entering the vehicle.

-Press[ ~]~ page 126, fig. 137 ~ &
Switching off the air recirculation
-Press~ again, or
- press [AUTO], or
press[ ®].
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]
Switching the air conditioning off
-Press [ OFF] to turn the air conditioner off and block
outside air from entering the vehicle.
Switching the air conditioning on
-Press [ OFF] again (indicator light comes on again), or

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. •

& WARNING (continued)
-The brake fluid must be new. Heavy use of the brakes can
cause a vapor lock if the brake fluid is left in the system too
long. This can seriously affect the efficiency of the brakes as
well as your safety. This could result in an accident.
0 Note
Brake fluid will damage the paint of your vehicle.
W For the sake of the environment
Because of the problem of proper disposal of brake fluid as well as
the special tools required and the necessary expertise, we recom­
mend that you have the brake fluid changed by your authorized Audi
dealer. •
Battery
General information
Under normal operating conditions, the battery in your Audi does
not need any maintenance. With
high outside temperatures it is
advisable however to check the fluid level at regular intervals
through the transparent battery housing. Also check the fluid level
each time you charge the battery. After charging the battery
~ page 289, you should likewise check the battery acid level.
Have the battery checked when you take your vehicle in for service.
You are well advised to replace a battery that is older than 5 years.
Preserving battery charge on a vehicle not operated
for a long time
Some components of the electrical equipment (for example, the
electronic immobilizer) will keep drawing a low current even when the car is
not running
. This will eventually drain the battery
completely if your vehicle is left sitting for a long period of time
without being driven . To prevent this, either charge the battery
occasionally or disconnect the battery negative (ground) cable.
Winter operation
During the winter months, battery capacity tends to decrease as
temperatures drop . This is because more power is also consumed
while starting, and the headlights, rear window defogger, etc., are
used more often.
Avoid unnecessary power consumpt ion, particularly in city traff ic or
when traveling only short distances. Let your authorized Audi dealer
check the capacity of the vehicle battery before winter sets in
~ page 289. A well charged battery will not only prevent starting
problems when the weather is cold, but will also last longer.
[ i] Tips
If your vehicle is left standing for several weeks at extremely low
temperatures, the vehicle battery should be removed and stored
where it will not freeze. This will prevent it from being damaged and
having to be replaced. •
Location of the vehicle battery
The vehicle battery is located in the plenum chamber at the back of
the engine
compartment~ page 275.
The positive(+) battery terminal is protected by a plastic cover. This cover must be removed to access to the positive(+) terminal when
connecting jumper cables to start the engine .
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS
~ & in "Working in the engine
compartment" on
page 273. •
