Climate controls
Controls
The air conditioning automatically maintains the selected
temperature in the vehicleinterior throughout each
se ason.
F ig. 76 C limate contro ls
We recommend the following setting:
- Rotate the knob~ fig. 76@ to the right to switch on the
ai r conditioning.
- Set the temperature to 72 °F (22 °C).
- Press the !AUTO
j ~ fig. 76 button.
Con tro ls and eq uip­
ment
W arm and cold
Using the previously recommended setting is the quickest way to
achieve a comfortable climate in the vehicle. This setting should
therefore only be changed when personal comfort levels or certa in
circumstances require it.
The climate controls are a combination of automatic heating and
ventilation systems and a cooling system which dehumidifies and cools the air inside the vehic le .
The climate controls automatically maintain a temperature once it has been set. The temperature of the air from the vents, fan speed
(air volume) and air dist ribu tion are a lso automatically adjus ted . The
system also takes into account strong sunshine so that manual
adjus tment is not necessary. So in almost all cases,
a ut omatic mode
offers the best conditions for the comfort of the occupants at all
times of the year~
page 88.
Ple ase not e:
In cooling mode, relative humidity in the interior is reduced. This
prevents the windows from fogging up .
When relative humidity and temperatures outside are high,
conden ­
s ate
can drip from the air conditioning evaporator and form a pool
of water under the vehicle . This is normal and not an indication of a
leak!
When outside temperatures are low, the fan does no t switch to a
higher speed until the coolant has reached an adequate tempera­
ture, with the exception of t he defrost setting .
When accelerating at wide-open throttle, the air conditioning compressor is temporarily switched off to maintain fu ll engine
power.
In order to ensure engine cooling under extreme engine loads, the
compressor is switched off if coolant temperatures climb too high ...

The pollutant filter (particle filter) ensures that contaminants in the
outside air (such as dus t or p ollen) are greatly reduced or stopped.
The air is also filtered in recirculation mode.
T he pollutan t fil te r element must be changed accord ing to the inter ­
vals specified in the maintenance schedule so that the air condi­
tioning system's performance is not adversely affected.
If the filter's effectiveness is weakened by driv ing t he vehic le in
areas with heavi ly polluted outside air, the filter element should also
be changed in between the listed services .
& WARNING
For safety re ason s, it is impo rtant that all window s are free of i ce ,
snow, and condensat ion . Onl y then is good visibility ensured .
Plea se familiari ze your self with the correct operation of the air
conditioning and how to dehumidify /defrost the windows .
0 Note
• If you suspect that the climate controls have been damaged,
switch the system off to avoid damag ing it, and have it inspected by
an author ized Audi dealer.
• Audi climate control system repairs require special expertise and
t he proper tools. You shou ld contact an authorized Audi dealer in
the event o f malfunctions.
[ i ] Tips
• To avo id adverse ly affecting heating and cooling performance
and to prevent condensation on the windows, the air intake in front
of the windsh ield must be free of ice, snow, and leaves.
• The air coming from the vents and circulating through the entire
inter ior is extracted through the outlet slots in the side panels in the
luggage compartment. Make sure that the outlet slots are not
covered by clo th ing, etc.
• Climate control works most effectively if the windows are closed .
H owever, if the interior of a parked vehicle is extremely hot from the
sun's rays, briefly opening the windows can speed up the cooling
process. •
Setting temperature
Tur n th e rota ry kno b G) ~ page 85, fig. 7 6 to t he des ired
t e mperature sett ing .
~

To set a lower temperature, turn the rotary knob to the left. To set a
higher temperature, turn the rotary knob to the right. There are addi ­
tional intermediate settings available to adjust the temperature as
needed. •
Switching climate control on and off
Switching the climate control system on and off
- Turn the knob@==> page 85, fig. 76 to the right to switch
climate control on. The LED next to the word OFF goes
out.
Turn the knob@==>
page 85, fig. 76 to the left to switch
the climate control system off. The LED next to the word
OFF comes on.
Setting fan speed ~
- Turn the knob @==> page 85, fig. 76 to the setting you
want to adjust fan speed (air quantity).
In automatic mode the climate control system automatically regu­
lates fan speed depending on interior temperature. You can adjust
the volume of air produced by the fan to meet your own require­ ments .
[ i] Tips
If the difference between the desired temperature set by you and
the vehicle's interior temperature is too great, the fan speed will change automatically. This is done so that the desired temperature
setting is reached as quickly as possible. •

Using the climate controls economically
E conomical use of the climate c ontrols helps to save fuel.
When climate control is working in cooling mode, engine
performance is reduced and fuel consumption is affected.
To keep the t ime the air cond itioning is on as s hort as
poss ible, you s hould do the following:
Controls and equip ­
ment
W arm and cold
- If you would like to save fuel, swit ch the air conditioning
off .
- If you open the windows while driving, switch the air
conditioning off .
- If the veh icle is extremely hot due to the heat of the sun,
briefly open doors and windows.
'£> For th e sake of th e environm ent
When you save fuel, you reduce emissions from the vehicle. •
Rear window defogger [ffiJ
The rear window defogger clears the rear window of
condensati on.
- Press the QuJ bu tton~ page 85, fig. 76 to turn the rear
window defogger on and off.
The rear window defogger works on ly when the engine is running.
The indicator light in the button illuminates when the rear window defogger is turned on.
The rear window defogger is switched off automatica lly after 10 to
20 minutes, depending on the outside temperature .
At very low outside temperatures, the rear window defogger can be switched on continuously by pushing the
Qiil button for more than 2
seconds. This remains stored until the ignition is switched off. A
rear window defogger that was switched on also remains stored for
15 minutes after the ignition is switched off.
If the engine is restarted within these 15 minutes, the rear window
defogger is activated for 10 to 20 minutes, depending on outside
temperature . With a vehicle that is parked for a short time, the rear
window defogger does not need to be manually activated again. .,,_

Quality grades can be found where applicable on the tire side wall
between tread shoulder and maximum section width
=> page 246,
fig. 152.
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. •
Winter tires
Winter tires can improve vehicle handling on snow and
ice. At temperatures below 45 °F (7 °C) we recommend
changing to winter tires.
In some heavy snow areas, local governments may require true
winter or "snow" tires, those with very deeply cut tread. These tires
should only be used in pairs and be installed on all four wheels.
Make sure you purchase snow tires that are the same size and
construction type as the other tires on your vehicle.
I f your vehicle is equipped with all-wheel drive *, this will improv e
traction during winter driving, even with the standard tires.
However, we strongly recommend that you always equip all four
wheels on your vehicle with correctly fitted winter tires or all-season
tires, when winter road conditions are expected. This also improves
the vehicle's braking performance and reduces stopping distances.
Summer tires provide less grip on ice and snow.
