Warm and cold
Climate control system
Description
The climate control system warms, cools and re­ moves humidity from the air in the vehicle interi­
or. It is the most effective when the windows and
sunroof * are closed. If there is a bui ld-up of heat
insid e the vehicle, ventilation can he lp to speed
up the cooling process.
I n all heating mode f unctions, except for defrost,
the blower only switches to a higher speed once
the engine coolant has reach ed a suffici ent tem­
perature .
Pollutant filt er
The po llutant filter removes poll utants such as
dust and pollen from the a ir .

A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free of
ice, snow and fog .
- Become familiar as quickly as possible with the correct use and function of the cl imate
contro l system, especially with the defrost­
ing and defogg ing function.
- When the temperat ure is below freezing,
only use the windsh ield washer system after
60
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshie ld and impair visibi li­
ty .

Airbag syste m
-If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child restraint system on
this seat .
- Never use cushions, pillows, blankets, or
similar items on the front passenger seat.
The additional layers prevent the capacitive
passenger detection system from accurately
measuring the capac itance of the ch ild safe­
ty seat and/or the person on the seat and
th us keep the Advanced Airbag System from
working properly .
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heater
for child seats) on the front passenger seat if the device is connected to the 12-volt
socket or the cigarette lighter socket. Such devices can influence the capacitance reg is­
tered by the capac itive passenger detection
system, so that incorrect information is pro­
vided to the airbag control unit.
- If you must use a child restraint on the front passenger seat and the child restraint man­
ufacturer's instructions require the use of a
towel, foam cushion or something else to properly position the ch ild rest raint, make
certain that the
PASSENGER AIR BAG OFF
light comes on and stays on whenever the
child restraint is insta lled on the front pas­
senger seat.
- If the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in­
stall child restraint in a rear seating position
and have the airbag system inspected by
your Audi dealer.
A WARNING
If the front passenger seat gets wet, dry it im­
mediately.
- If liquid soaks into the front passenger seat,
this can keep the a irbag system from work­
ing properly and may, for instance, deact i­
vate the passenger frontal airbag. If this
happens, the
PASSENGER AIR BAG OFF
ligh t will come on and stay on togethe r with
the airbag indicator light
II (USA models) I
156
E,I (Canada mode ls) in the instr ument clus­
ter.
- If liq uid is pooled on the seat, but has not
soaked in, th is may also keep the airbag sys­
tem from working proper ly and cause the
passenger frontal airbag to be enabled
(turned on), even though there is a p roperly
installed child restraint system on the seat.
Wet towels or other wet things on the seat
cushion can have the same effect. If the
front p assenger front al airbag is turned on,
the
PASSENGER AIR BAG OFF light ligh t
wi ll go out.
How the Advanced Airbag System
components work together
The front Advanced A irbag System and the side
airbags supp lement the protection offered by the
front th ree-point safety belts with pretens ioners
and load lim ite rs and the adj ustab le head re­
straints* to help reduce the risk of i njury in a
wide range of accident and cras h situations. Be
s ur e to read the impo rtant informat ion about
sa fety and heed the WARNINGS in this chapter.
Deployment of the Advanced A irbag System and
the activa tion of the safety belt pretens ioners de­
pend on the dece lera tion measured by the crash
senso rs and registered by the electronic contro l
unit . Crash severity depends on speed and decel­
eration as well as the mass and stiffness of the
vehicle or object involved in the crash.
On the passenger side, regard less o f safety be lt
use, the front passenger frontal airbag will be
turned off if the e lectrica l capacitance measured
by the capacitive passenger detection system on
the front passenger seat is less than the amount
programmed in t he e lectronic contro l unit . The
front passenger frontal a irbag w ill also be tur ned
off if the capacitance measured by the system for
t h e front passenger seat equals that of an infant
of about o ne yea r of age in one o f the ch ild sea ts
that was used to certify the Advanced Airbag Sys­
tem under Federa l Motor Vehicle Safety Standard
208. The
PASSENGER AIR BAG OFF light comes
on and stays on to tell you when the front Ad­
vanced Airbag System on the passenger side has been turned off¢

The PASSENGER AIR BAG OFF light will show
the status of the front seat passenger's frontal
Advanced Airbag a few seconds after the igni­
tion is switched on and the airbag indicator
light goes off . The PASSENGER AIR BAG OFF
light:
- will stay on if the front passenger seat is not
occupied;
- will stay on if the electrical capacitance meas­
ured by the capacitive passenger detection sys­
tem for the front passenger seat equals the
combined capacitance of an infant up to about
one year of age and one of the rearward-facing
or forward-facing child restraints listed in Fed­
eral Motor Vehicle Safety Standard 208 w ith
which the Advanced Airbag System in your veh i­
cle was certified; For a list ing of the child re­

- The
PASSENGER AIR BAG OFF light must come
on and stay on if the ignition is on and . ..
- a car bed has been insta lled on the front pas­
senger seat, o r
- a rearward-facing child res traint has been in ­
stalled on the front passenger seat, or
- a fo rw ar d-fa cing child restraint has bee n ins tal­
led on the front passenge r seat,
- and if the electrica l capacitance registered on
the front passenger seat is equa l to or less than
the combined capacitance of a typica l 1 year­
o ld infant and one of the rearward-facing or
forward-facing child restraints listed in Federal
Motor Vehicle Safety Standard 208 with which
the Advanced Airbag System in your vehicle was certified.
If the front passenger seat is not occupied, the
front airbag will not deploy, and the
PASSENGER
AIR BAG OFF
light will stay on. Never install a
rearward-fac ing ch ild restraint on the front pas­
senger seat, the safest place for a child in any
160
kind of child restraint is at one o f th e seating po ­
sitions on the rear seat¢

If the PASSENGER AIR BAG light comes
on ...
If the PASSENGER AIR BAG OFF light comes on
when one of the conditions listed above is met,
be sure to check the light regularly to make cer­
ta in that the
PASSENGER AIR BAG OFF light
stays on continuously whenever the ignition is
on. If the
PASSENGER AIR BAG OFF light does
not appear on and does not stay on a ll the time,
stop as soon as it is safe to do so and
- reactivate the system by tur ning the ignition
off for more than 4 seconds and then turning it
on again;
- remove and re install the child restraint. Make
sure that the child restraint is properly insta l­
led and that the safety belt for the front pas­
senge r seat has been corre ctly routed through
the child restraint as described in the child re­
straint manufacturer's instructions;
- make sure that the convertible lock ing retrac­
tor on the safety belt for the front passenger
seat has been activated and that the safety belt
has been pulled tight.
- make sure that no e lectrica l device (suc h as a
laptop, CD player, e lectronic games device,
power inverter or seat heater for child seats) is
placed or used on the front passenger seat if
the device is connected to the 12-volt socket or
the cigarette lighter socket;
- make sure that no seat heater has been retro­
fitted or otherw ise added to the front passen­
ger seat;
- make sure that noth ing can interfere with the
safety belt buckles and that they are not ob­
structed;
- make sure that there are no wet objects (such
as a wet towel) and no water or other liquids on
the front passenger seat cushion. .,.

Child safety
A WARNING
Children on the front seat of any car even with
Advanced Airbags can be seriously injured or even killed when an airbag inflates. A child in
a rearward-facing child safety seat installed
on the front passenger seat will be serious ly
injured and can be killed if the front a irbag in ­
flates .
- The inflating a irbag w ill hit the child safety
seat or infant carrier with great force and
will smash the chi ld safety seat and child
against the backrest, center armrest, or
doo r.
- Always install rear-facing child safety seats
on the rear seat.
-If you must install a rearward fac ing ch ild
safety seat on the front passenger seat in
exceptional circumstances and the
PASSEN­
GER AIR BAG OFF
light does not come on
and stay on, immediately install the rear ­
facing child safety seat in a rear seating po­
sition and have the airbag system inspected
immediately by your Audi dealer.
A WARNING
- Forward-facing child seats installed on the
front passenger seat may interfere with the deployment of the a irbag and cause serious
personal injury to the child .
- If except ional circumstances require the use
of a forward -facing child restraint on the
front passenger's seat , the child's safety
and well-being require the following special
precautions to be taken:
- Always make sure that the forward-facing
seat has been designed and certified by its
manufacturer for use on a front passenger
seat with a front and s ide a irbag.
-Always carefully follow the manufacturer's instructions provided with the child seat
or infant carrier.
- Never install a child restraint without a
properly attached top tether strap if the
child restraint manufacturer's instructions
require the top tether strap to be used.
172
-Never put the forward-fac ing child re­
straint up against or very near the instru­
ment panel.
- Always set the safety belt upper anchor­
age to the adjustment position that per­
mits proper installation in accordance
with the child restraint manufacturer's in ­
structions .
- Always move the front passenger seat to
the h ighest position in the up and down
adjustment range and move it back to the
r earmos t position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible, before installing
the forward-facing child restraint.
- Always make s ure that the safety belt up­
per anchorage is behind the child restraint
and not next to or in front of the child re­
straint so that the safety belt wi ll be prop­
erly pos itioned.
- Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its fore
and aft adjustment range.
- Never place objects on the seat (such as a
laptop, CD player, electronic games de­
v ice, power inverter or seat heater for
ch ild seats). These may influence the elec­
trical capacitance measured by the capaci­
tive passenger detection system and can
also fly a round in an accident and cause
serious personal injury.
- Never place or use any elect rical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heat­
er for child seats) on the front passenger
seat if the device is connected to the 12-
vo lt socket or the cigarette lighter socket.
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys­
tem on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or oth­
er liquids on the front passenger seat
cush ion .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays on

Child safety
-The child and the passenger can also in­
jure each other in an accident.
- Never install rear-facing child safety seats
or infant carriers on the front passenger
seat. A child will be seriously injured and
can be killed when the passenger airbag in­
flates - even with an Advanced Airbag Sys­
tem.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, door
or roof.
- Always install rear-facing child safety seats
or infant carriers on the rear seat.
- Make sure there is enough space in front of
the child in the child seat. If necessary, ad­
just the angle and position of the seat in
front of the child seat.
- Forward-facing child safety seats installed
on the front passenger's seat can interfere
with the airbag when it inflates and cause
serious injury to the child. Always install for­
ward-facing child safety seats on the rear
seat.
- If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety
and well-being require that the following
special precautions be taken:
- Make sure the forward-facing seat has
been designed and certified by its manu­
facturer for use on a front seat with a pas­
senger front and side airbag.
- Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.
- Always move the front passenger seat to the highest position in the up and down
adjustment range and move it back to the
rearmost position in the seat's fore and
aft adjustment range, as far away from
the airbag as possible, before installing
the forward-facing child restraint.
- Always make sure that the safety belt up­
per anchorage is behind the child restraint
and not next to or in front of the child re-
176
straint so that the safety belt will be prop­
erly positioned.
- Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its fore
and aft adjustment range.
-Always make sure that the backrest is in the upright position.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heat­
er for child seats) on the front passenger seat if the device is connected to the 12-
volt socket or the cigarette lighter socket.
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys­
tem on this seat.
- Make sure that there are no wet objects
(such as a wet towel) and no water or oth­
er liquids on the front passenger seat
cushion.
- Never place objects on the seat (such as a
laptop, CD player, electronic games de­
vice, power inverter or seat heater for
child seats). These may influence the elec­
trical capacitance measured by the capaci­
tive passenger detection system and can
also fly around in an accident and cause
serious personal injury.
- Always buckle the child safety seat firmly in
place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a collision .
