Warm and cold Climate control system
Description
Different systems could be installed.
- manual climate control system* or
- automatic climate control system*
The
climate control system* cools and re­
moves humidity from the air in the vehicle in­
terior. It is the most effective when the win­
dows and power top are closed. If there is a
build-up of heat inside the vehicle, ventila tion
can help to speed up the cooling process. Be­
cause of this, the windows can be opened
from outside .
~ page 39, Convenience open­
ing/closing
Pollutant filter
The pollutant filter removes pollutants such
as dust and pollen from the air .
Key recognition
You can store various settings for the manual
and automatic
climate control system* and
assign them to the key being used .
A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep a ll windows free
of ice, snow and fog.
- Become familiar as quickly as possible
with the correct use and function of the
climate control system, especially with
the defrosting and defogging function .
- When the temperature is below freezing,
only use the windsh ield washer system
after the w indshield has been warmed by the cl
imate control system . The washer
fluid could freeze on the windshield and
impair visibility.
(D Note
- If you suspect that the climate control
system is damaged, switch the system
off to prevent further damage and have
it checked by an authorized Audi dealer
or authorized Audi Service Facility.
- Repairs to the Audi climate control sys­
tem require special technical knowledge
and special tools. See an authorized Audi
dealer or authorized Audi Serv ice Facility .
® For the sake of the environment
Reducing the amount of fuel used also re­
duces the amount of pollutants that enter
the air.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the
w indows from fogging over, the air in­
take in front of the windshield must be
free of ice, snow or leaves.
- Condensation from the cooling system*
can drip and form a puddle of water un­
der the vehicle. This is normal and does
not mean there is a leak.
- T he energy management system may
switch the seat heating* or rear window
defroster off temporari Ly. These systems
are available again as soon as the energy
balance has been restored.
- The flows through the vents under the
rear window. Make sure the openings are
not covered when placing clothing on the
luggage compartment cover.

Manual climat e control system*
For a comfortable temperature, we recom­
mend :
- in warmer times of the yea r, set the temper­
atu re so that it is only a few degrees be low
the outside tempe ratu re.
- set the blower at a moderate speed
- don't direct the air flow d irectly on the pas-
sengers
IA/C l Switching the cooling mode* on and
off
The cooling mode only f unct ions w ith the

h umidity is not removed when cooling mode
i s swit ched off. This c an cause fog o n the w in­
dows. The cooling mode sw itches off auto­
matica lly in co ld outside temperatures (below
32 °F/0°C) .
~ Adjusting the blower
To prevent the windows from fogging over,
the blower sh ou ld always ru n at a low speed.

1- 1 Sw itching r ecircul ation mode on and
off
In recirculation mode, the air inside the vehi ­
cle is circu lated and filtered. This prevents the
unfiltered air outside the vehicle from enter­ ing the vehicle inter ior. We recommend
switch ing recirculation mode on when driving
through a tunnel or when sitt ing in traffic

Automatic climate control syst em
We re commend pressing the IAU TO I button
and setting the temperature to 72
°F (22 °() .
The automatic climate control system auto­
matica lly ma inta ins a temperature once it has
been set. The temperature of the air from the
vents, the b lower speed, and air distribution
are also automat ically adju sted . In all heat ing
mode funct ions except
defrost, the blower
only switches to a h igher speed once the en­
g ine coolant has reached a certa in tempera­
ture . Recirculation mode is switched off in the de­
frost setting ~-
.&_ WARNING
-You shou ld not use the recirculation mode
for an extended period s ince no fresh air is
drawn in. With the air-conditioning*
switched off, the w indows can fog up,
which increases the risk of an acc ident .
IA/ Cl Switching th e cooling mode on and
off
T he cooling system is turned on and off with
the
IA/C l button. The air is not coo led and hu­
mid ity is not removed when cooling mode is
switched off . This can cause fog on the win­
dows . The cooli ng mode switches off auto ­
matically i n cold outside temperatu res (be low

I• I • I S etting the temperatu re
The temperature can be adjusted individually
for the driver and front passenger using the
dials . Temperatu res between 60 °F (+16 °C)
and 84 °F (+28 °C) can be set . Outs ide of this
range,

ture is not regu lated.
Syn chroni zation: By pressing the !AU TO I but ­
ton for two seconds , the temperat ure setting
for the driver is transferred to the front pas­
senger's side. This applies a temperature
change to the front passenger's side.

254 Tires and wheels
run flat tires. If run flat tires
are used, they must be in­
stalled on all four wheels. Mixing tire types is not per­
mitted.
@) Note
-For technical reasons, it is not generally possible to
use the wheel rims from
other vehicles. This can hold
true for wheels of the same
vehicle type.
- If the spare tire is different
from the tires that you have mounted on your vehicle
(for example winter tires or
wide prof ile tires), then use
the spare tire for a short pe­
riod of time only and drive
with extra care. Replace the
flat tire with the tire match­ ing the others on your vehi­
cle as soon as possible.
- Never drive without the
valve stem cap . The valves
could get damaged.
@) For the sake of the environment
Dispose of old tires in accord­
ance w ith the local require­
ments.

Quality g rades can be foun d where applicab le
on the t ire s ide wall between t read sho ulder

All passenge r ca r tir es must con fo rm to Feder ­

grades.
Tread wear
T he tread we ar g rade is a c omparative r ati ng
b as ed on the wea r ra te of the tire when tes ted
u nder con tro lled cond itions o n a specifie d
government test course .
F o r ex am ple, a tire gr aded 1 S0 would wear
o n e and one h alf ( 11/ 2) times as well on the
government course as a tire gr aded 10 0 .
T he re lative per forman ce of tires depen ds
up on the actu al cond itions of the ir use, h ow­
ever, and m ay dep art s ignific antly from the
no rm due to va ria tions i n driving ha bits, se rv ­
ice p ractices and differe nces in road c haracter­
ist ics and climate.
Traction
The tr actio n gr ad es, fro m hig hest to lowest,
are AA, A, Ban d
C. Those grades represent t he

Temperature
The temperature g rades are A (the highest),
