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.

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 .•

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. •

Power steering
Power steering makes it easier to steer the vehicle when
the engine is running.
If the engine is not running the power steering does not work and
you will find it more difficult to turn the steering wheel.
Whenever the steering wheel is turned all the way to the left or right
a lo t of stress is placed on the power steering pu mp. When this
happens you will hear a noise coming from the power steering
pump .
0 Note
Never hold the steering wheel turned all the way to the left or right
longer than 15 seconds when the en gine is running -damage to
the power steering system is likely! •

dent.
0 Note
Only after the vehicle has come to complete stop, should you firmly
set the parking brake and either move the gearshift lever into 1st.
gear (manual transmission) or move the selector lever into
"P"
(Automatic transmission).•
Parking
To prevent a parked vehicle from rolling away, there are a
few things you should do.
When you park your vehicle, do the following:
-Stop the vehicle using the brake pedal.
-Set the parking brake firmly.
-Move the selector lever into the P position ~ &.
-Switch off the engine and remove the ignition key from
the ignition lock.
What else you should do when parking your vehicle on
an incline or decline
Turn the steering wheel so that if the vehicle should start to roll, it
will roll into the curb.
If you are parking on a
decline (the front of your vehicle facing
downhill), turn the front wheels to the right so that they point
toward the curb.
If you are parking on an incline (the front of your vehicle facing
uphill), turn the front wheels to the left so that they point
away from
the curb.
Move the selector lever into the P position.
& WARNING
This is how you can reduce the risk of injury when leaving your
vehicle.
• Never park the vehicle where it can come in contact with dry
grass, spilled fuel or any other flammable materials.
• Never allow anyone -especially small children -to remain in the
vehicle when it is locked. Locked doors make it more difficult for
rescuers to access the passenger compartment in the event of an
emergency. Danger to life!
• Never leave children unsupervised in the vehicle. Children
could release the parking brake or move the gearshift lever out of
gear. The vehicle could start to roll away and cause an accident.
• No matter what the season is, the temperature in a parked
vehicle can reach dangerous levels. •
