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.

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. •

A cold engine may at first be loud after it has been started. This is
due to the hydraulic valves building up the oil pressure . This is
normal and no need for concern.
If the engine does not start immediately, stop trying after 10
seconds and then try to restart the engine about 30 seconds later.
What to do if the engine does not start
• ~ page 330
• ~ page 332, "Emergency towing with commercial tow truck"
_& WARNING
Never start or let the engine run in a confined or enclosed area.
Exhaust fumes from the engine contain carbon monoxide, a color­
less and odorless gas. Carbon monoxide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft.
