Climate controls
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recomme nd the following s ettings:
- Select and set a temperature between 64
°F (+22 °C) and
84 °F (+28 °C).
- Press the !AUTO
I button.
With this setting, you attain maximum comfort in the least amount
of time . Change this set ting, as desired, to mee t your pe rsonal
needs.
The climate controls are a combination of heating, venti lation and
cooling systems, which automatica lly reduce humidity and coo l the
air inside your vehic le .
The air temperature, air flow and air distribution are automatically
regu lated to achieve and maintain the desired passenger compart ­
ment temperature as quick ly as possible.
The system automatically compensates for changes in the outside
temperature and for the intensity of the sun light entering the
vehic le. We recomme nd you use the
Automati c mode~ page 99for
year -round comfort.
P lease note the following :
Turn on the air conditioner to reduce humidity in the vehic le. This
a lso prevent the window s from fogging up. When the outside temperature is high and the air is very humid,
c
ondensat ion from the evaporator may drip under the vehicle . T his
is normal and does not indicate a leak.
I f the outside temperature is low, the fan normally only switches to
a higher speed once the engine coola nt has war med u p sufficiently .
T he air conditioner temporarily sw itches off when you drive off from
a standstill using fu ll throttle to save engine power.
The comp ressor also swi tches off if the coolant temperatu re is to o
high so that the engine can be adequate ly cooled under extreme
lo ads .
Air pollutants filt er
The air po llutants fi lter (a combined partic le filter and activated
charcoal fi lter) reduces or eliminates outside air pollution (dust, or
p ollen) from en ter ing the vehic le .
The air po llutants fi lter must be changed at the intervals specified
in your Warranty
& Maintenance bo oklet, so that the ai r conditioner
can proper ly work.
I f you drive your vehicle in an area with high air pol lution, the filter
may need to be changed m ore freque ntly tha n specified in your
Audi Warranty
& Maintenance booklet. If in doubt, ask your autho­
r iz ed Aud i Service Adviso r fo r a dvice .
& WARNING
Redu ced vi sibility i s dangerou s and can cause accidents .
• For saf e driving it is very important that all window s be free of
ice , sno w and conden sation.
• Fully familiarize yourself with the proper use and fun ction of
the heating and ventil ation sy stem and especially how to defog
and defrost the windows. ...

What impa
irs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also
become a hazard to everyone else on the road =>& .There ­
fore:
Do not let yourself be distracted by passengers or by
using a cellular telephone .
NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense .
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed .
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •
