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.
...

___ w_ a_ rm __ a_ n_ d_ c_o_ ld __________________________________________________ _
& WARNING (continued )
• Never use the wind shield wiper /washer system in freezing
weather until you have warmed the windshield fir st, using the
heat ing and ventil ation sy stem . The washer solution may freeze
on the wind shield and reduce visibility .
0 Note
• If yo u suspect that the air conditioner has been damage d, swi tch
on ECO N and contact an au thorized Audi deale r to have the system
inspecte d.
• Repairs to the Audi air conditioner require specia l techn ical
k nowledge and special tools . Contact an authorized Audi dea ler for
assistance.
[ i ] Tips
• K eep the air intake slots (in front of the windshie ld) free from ice,
snow and debris in order to mai ntain the proper function o f the
climate control system .
• Air escapes through ven ts u nder the rear window . When plac ing
items of c lothing on the luggage compartment cover , ensure that
t he openings are no t covered .
• I f the inside temperatu re is very high (for example, if the vehicle
h as been parked in sun), open t he wi ndows an d allow the hot air to
escape before turning on the ai r conditioner .•

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. •
App lies to ve hicles: w ith e lec tric ally heat ed front seats
Electrically heated front seats
With the ignition on, the seat cushion and backrest of the
front seats can be heated.

• Never drive without the valve stem cap. The valves could get
damaged.
• If the sensors must be replaced, then the valve must also be
replaced at the same time.
For the sake of the environment
Dispose of old tires in accordance with the local requirements.•
Uniform tire quality grading
• Tread wear
• Traction AA A B C
• Temperature A B C
Quality grades can be found where applicable on the tire side wall
between tread shoulder and maximum section width
=> page 305,
fig. 221.
For example: Tread wear 200, Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Require­
ments in addition to these grades .
Tread wear
The tread wear grade is a comparative rating based on the wear rate
of the tire when tested under controlled conditions on a specified
government test course .
For example, a tire graded 150 would wear one and one half (1 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual condi­
tions of their use, however , and may depart significantly from the
norm due to variations in driving habits, service practices and differ ­
ences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, Band C.
Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government
test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance
=> & .
Temperature
The temperature grades are A (the highest), B, and C, representing
the tire's resistance to the generation of heat and its ability to dissi­
pate heat when tested under controlled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire
failure =>& .
The grade C corresponds to a level of performance which all
passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades Band A represent higher levels of
performance on the laboratory test wheel than the minimum
required by law .
& WARNING
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established for a tire that is
properly inflated and not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or in combination, can
cause heat buildup and possible tire failure.
