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 following settings:
- Set the temperature to 75
°F (+23 °C).
- Press the
[AUTO] button.
With this setting, you attain maximum comfort in the least amount
of time. Change this setting , as desired , to meet your personal needs.
The climate controls are a combination of heating, ventilation and cooling systems, which automatically reduce humidity and cool the
air inside your vehicle .
The air temperature, air flow and air distribution are automatically regulated to achieve and maintain the desired passenger compart­
ment temperature as quickly as possible.
The system automatically compensates for changes in outside
temperature and for the intensity of the sunlight entering the
vehicle. We recommend you use the
Automatic mode ~ page 106
for year-round comfort .
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This also
prevents the windows from fogging up.
When the outside temperature is high and the air is very humid,
condensation from the evaporator may drip under the vehicle . This is
normal and does not indicate a leak.
Controls and equip ­
ment Safety first
If the outside temperature is
low, the fan normally only switches to a
higher speed once the engine coolant has warmed up sufficiently .
The air conditioner temporarily switches off when you drive off from
a standstill using full throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high, so that the engine can be adequately cooled under extreme
loads.
Air pollutants filter
The air pollutants filter (a combined particle filter and activated char­
coal filter) reduces or prevents outside air pollution (dust, or pollen)
from entering the vehicle.
The air pollutants filter must be changed at the intervals specified in
your Warranty
& Maintenance booklet, so that the air conditioner can
properly work.
If you drive your vehicle in an area with high air pollution , the filter
may need to be changed more frequently than specified in your Audi
Warranty
& Maintenance booklet. If in doubt, ask your authorized
Audi Service Advisor for advice.
Key coded settings
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 driver will maintain his/her own personal settings and
does not have to reset them manually.
If a different driver uses your key and changes the air conditioner
settings, the latest adjustments will erase and replace the settings
you have stored.
Energy management

(I) Tips
If the climate control system is operating in cooling mode , air flows
p rima rily from th e outlets in the center console and in the door
pillars . T o ach ieve adequa te cooling, you should never close the
ou tle ts completely. •
Using climate controls economically
Using the climate controls prudently can help save fuel.
When you use the a ir conditioner, e ngine power is reduced
and fuel consumption increa ses. To save fu el, you should use
the air co nditioner o nly when necessary. Also please note the
following points :
If you want to save fuel , activate ECON .
If you are going to drive with the wi ndows open, use ECO N.
~ For the sake of the environment
By reducing t he amount of fuel you use, you also reduce the amou nt
of pollutants emitted into the air .•
A ppli es to vehicl es : w ith sola r sliding /til tin g sunroof
Solar blower fan /solar roof
With sufficient sunlight, the blower fan continues to
operate with solar energy to bring in fresh air after the
ignition has been switched off
The fan motor is operated by solar energy throug h the solar roof after
t he ignition is tur ned off . P lease make certai n that vents @ and ©
are ope n to ach ieve op timal ventilation =:,
page 111, fig. 124.
The venti lation operates on ly with the sunroof closed or in the ti lted
position. If the veh
icle was switched off in the rec irculat ion mode, the air
condi tioning au tomatically sw itches to fresh a ir operation .
Solar operation is not activated at low outside temperatures .•

and off=> fig. 125.
T he windsh ield defogger works only when the engine is runn ing . T he
ind icator light in the button illum inates when the windshield
defogger is turned on.
With a cold engine at outside temperatures below 41 °F (+5 °C) and i n
( AU TO] operation, the windshield defogger turns on automati­
cally . Depend ing o n outside temperat ure, the w indshie ld is heated
for a maximum of 4 m inutes. The temperature for the climate control
must be selected so tha t it is ope ra ting in the heat ing mode . .,_

Warm and cold -_______________ __.
When selecting the program setting®, the windshield
defogger/defroster is switched on automatically at outside tempera­
tures below 41
°F (+5 °(). Depending on outside temperature, the
windshield is heated from 2 up to a maximum of 4 minutes .
Th e windshield defogger is deactivated in ECON mode.
(I] Tips
• If a crack forms in the windshie ld due to a foreign object (e.g. a
stone chip), the defogger/defroster is not turned on. This prevents
the crack from spreading.
• We recommend that you locate an Audi dealership immediately to
have the windshie ld replaced. •

m en t Vehicle
OP-eration
The rear window defogger will switch off automatically after a short
time. The time the rear window defogger remains on will vary
depending on the outs ide temperature.
At very low outside temperatures, the rear window defogger can be
switched on continuously by push ing the
CiiiJ button for more than 2
seconds. This rema ins stored until the ignition is switched off.
A rear window defogger that was switched on also remains stored for
15 m inutes after the ignition is switched off . If the engine is
restarted within these 15 minutes, the rear window defogger is a lso
act ivated, depending on outside temperature . W ith a vehicle that is
parked for a short time, the rear window defogger does not need to
be manually activated again.
<£> For the sake of the environment
T urn the defogger off when the rear w indow is clear. When you save
electricity, you save fuel. •

a service facility . The electrolyte level should also be checked each
time the battery is charged =>
page 303.
Have the batte ry checked when you take your vehicle in for serv ice .
You are well advised to rep lace a battery that is older than 5 years.
With certa in types of a irbag deployment, the ba ttery is disconnected
from the vehicle electrical system for safety reasons=>
& in "Repair,
care and disposal of the airbags" on
page 220.
Di sconne cting th e bat tery t ermina ls
Some vehicle f unct ions (power window regulators, fo r example) are
lost if the battery termina ls are disconnected . These functions have
to be re learned after the battery termina ls are connected aga in. To
prevent this, t he battery should only be disconnected from the
vehicle e lectr ica l system when absol ute ly necessary for repairs.
Vehicles not driven for long periods
If you do no t dr ive your veh icle over a period of severa l days or weeks,
electrical components are gradually cut back or switched off. Th is
red uces e nergy consumption and main tains sta rt ing capabili ty ove r a
longer period=>
page 258.
Be aware that when you unlock your vehicle, some of the convenience
functions may not operate, such as the Convenience key*, the remote
control or the power seat adjustment. The convenience functions will
be availab le aga in whe n you tur n on th e ignition and start the eng ine.
Winter operation
Dur ing the winter months, battery capac ity tends to decrease as
temperatures drop. This is because more power is also consumed
while starting, and the headlights, rear w indow defogger, etc., a re
used more often.
Avoid unnecessa ry power consum ption, part ic ula rly i n city traffic o r
when traveling only short distances. Let your authorized Audi dealer check the capacity of the vehicle battery before w inter sets in
=>
page 303 . A well charged battery will not only prevent start ing
prob lems when the wea ther is cold, but will also las t longe r.
Vehicle OP-eration
(I) Tips
If your vehicle is left standing fo r seve ral weeks at extremely low
temperatures, the vehicle battery should be removed and stored
w here it will not free ze. This will preven t it from being damaged and
having to be replaced. •
