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.
