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 w indows and
sliding sun roof* or power top* are closed . If
there is a build-up of heat inside the vehicle, ven­
tilation can help to speed up the cooling process.
I n all heating mode functions except for
defrost ,
the blower on ly switches to a higher speed once
the engine coolant has re ached a sufficient tem­
perature .
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
Key recognition
The climate control settings are automatically
stored and assigned to the remote control key
that is in use .
T hese settings are different when the power top*
is open or closed .
Warm and cold
{® For the sake of the environment
-If you would like to reduce fuel consump­
tion, switch the air conditioning off . This
will also reduce emissions.
- In vehicles with a diesel engine, you can
switch the auxiliary heater off in the Info­
tainment system.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the win­
dows from fogging over, the air intake 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 under the
vehicle . This is normal and does not mean
there is a leak .
- The energy management system may tem ­
porarily switch off certain functions, such as
the seat heating* or rear window defogger.
These systems are available again as soon
as the energy supply has been restored.

Airbag System for the front passenger seat from
doing its job in a crash.
The f ront Ad vanced Airb ag S ystem con sists
of t he follo wing :
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System about the severity of the crash.
-An electronic control un it, with integrated
crash sensors for front and side impacts. The
control unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors. The control unit also
"de­
c ides" whether the safety belt pretens ioners
shou ld be activated .
-An Advanced Airbag with gas generator and
contro l valve for the driver ins ide the steer ing
wheel hub.
-An Advanced Airbag with gas generator and contro l valve inside the instrument pane l for
the front passenger.
-A capac itive passenger detect io n system unde r­
neath the front passenger seat cover. This sys­
tem measures the elect rical capac ita nce of the
person in the seat. The i nformation registe red
is sent continuously to the electron ic control
unit to regulate deployment of the front Ad­
vanced Airbag on the passenger side.
-An airbag monitoring system and indicator
light
m in the instrument cluster .
-A sensor in each front seat reg isters the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation reg istered is sent continuously to the
electronic control unit to regulate deployment
of the front Advanced A irbags.
-The PA SS EN GER AIR BAG OFF ~; ON@ light
comes on in the
headliner ¢ page 289,
fig. 248 and tells you the status of the Ad­
vanced Airbag on the passenge r side .
-A sensor in the safety belt latch for the dr iver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transm its this info rmat ion to the elect ronic
contro l unit.
Airb ag sys tem
_& WARNING
Damage to the front passenger seat can pre­
vent the front airbag from working properly.
- Improper repair or disassembly of the front
passenger and driver seat will prevent the
Advanced Airbag System from funct ion ing
properly.
- Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personnel.
- Never remove the front passenger or driver seat from the vehicle.
- Never remove the upholstery from the front
passenger seat.
- Never disassemble or remove parts from the
seat or disconnect w ires from it.
- Never carry sharp objects in your pockets or
put them on the seat. The capacit ive pas­
senger detect ion mat in the front passenger
seat will not function p roperly if it is punc­
tured.
- Never carry things on your lap or carry ob­
jects on the front passenger seat. S uch ob­
jects can influence the capacitance reg is­
tered by the capacitive passenger detection
system, so that incorrect informa tion is pro­
vided to the airbag control unit.
- Never store i tems unde r the front passenger
seat . Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, p reventing them and the airbag sys­
tem from working proper ly.
- Never p lace seat covers or replacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats.
- Seat covers can prevent the Advanced A ir­
bag System from recognizing chi ld re­
stra ints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly.
- If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child restra int system on
this seat.
- Never use cushions, p illows, blankets, or
similar items on the front passenge r seat .

Airbag syste m
The additio na l l ayers 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
thus keep the Advanced Airbag System from
working p roperly.
- Never place or use any electrical device (such as a laptop, CD player, elect ronic
games dev ice, power inverte r or seat heater
for child seats) on the front passenger seat
if the device is connected to the 12-vol t
socket or the cigarette lighter socket . S uch
devices can infl uence the capacitance regis­
tered by the capacitive passenger detection
system, so that incorrect information is pro­
vided to the airbag control unit.
- If you must use a c hild 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 prope rly position the ch ild restraint, make
certain that the
PASSENGER AIR BAG OFF
~; light comes on and stays on whenever
the chi ld restraint is installed on the front
passenge r seat .
-If the PASSENGER AIR BAG OFF ~; light
does not come on and s tay on , immediate ly
ins tall child restra int in a rea r seating posi­
tion and have the airbag system inspected
by you r A udi dealer.
_& 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 prope rly and may, for instance, deact i­
vate the passenger frontal airbag. If this happens, the
PASSENGER AIR BAG OFF ~;
light will come on and stay on togethe r with
the a irbag ind icator
light E,I in the inst ru­
men t cluster.
- If liquid is poo led on the seat, bu t has not
soa ked i n, this may also keep the airbag sys­
tem from wo rking properly and ca use the
passenge r frontal a irbag to be enabled
(tu rned on), even though there is a properly
286
installed child rest raint system on the seat .
Wet towels or other wet things on the seat
cushion can have the same effect.
If the
front passenger fronta l airbag is turned on,
t he
PASSENGER AIR BAG OFF ~; light light
w ill go out.
How the Advanced Airbag System
components work together
The front Advanced A irbag System and the side
airbags supp lement the p rotection offered by the
front three-point safety be lts and the adjustable
head restraints to he lp reduce the risk of injury in
a wide range of accident and crash situat ions. Be
sure to read the important i nformat ion about
safety and heed the WARNINGS in this chapter .
Deployment of the Advanced A irbag System and
the activation of the safety belt pretensioners de­ pend on the dece leration measured by the crash
sensors and registered by the elec tronic contro l
u nit . Crash severity depends on speed and decel­
e ration as well as the mass and stiffness of the
vehicle or object invo lved in the cras h.
On the passenger side, regard less of safety be lt
u se, the front passenge r frontal airbag will be
turned off if t he e lectr ica l capaci tance m easured
by the capaci tive p assenge r detection system o n
t h e fron t passenger sea t is less th an the amou nt
programmed in t he e lec tronic cont ro l unit. The
front passenger frontal airbag wi ll also be turned
off if the capacitance measured by the system for
the front passenger seat equals that of an infant
of about one year of age in one of the child seats
that was used to certify the Advanced Airbag Sys­
tem under Federal Motor Vehicle Safety Standard 208. The
PASSENGER AIR BAG OFF ~; light
comes on and stays on to tell you whe n the front
Advanced Airbag System on the passenge r side
has been tu rned
off~ page 289.
_& WARNING
T o reduce the ris k of injury when an airbag in ­
f lates, always wea r safety belts prope rly.
- If you are un res trained, leaning forward, sit­
ting sideways or out of position in any way,
your r isk of injury is much higher.

A WARNING
Child ren on the front seat of any car even w ith
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 seriously
injured and can be killed if the front airbag in­
flates.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the ch ild safety seat and child
against the backrest, center armrest, or
door.
- 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
exceptiona l circumstances and the

GE R 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 chi ld 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 fo rward-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 chi ld restraint without a
properly attached top tether strap if the
child restraint manufacturer's instructions require the top tether strap to be used.
Ch ild safety
-Never put the forward-facing child re­
straint up against or very near the instru­
ment panel.
- Applies to: vehicles with safety be lt height
adjustment: Always set the safety belt up­
per anchorage to the adjustment pos ition
that permits proper installation in accord­
ance with the child restraint manufactur­
er's instructions.
- Always move the front passenger seat to the h ighest position in the up and down
adjustment range and move it back to the
rearmos t position in the seat's fore and
a ft ad justment range, as far away from
the a irbag as poss ible, before installing
the forward-facing child restraint .
- Always make sure that the safety belt up­
per anchorage is behind the chi ld restraint
and not next to or in front of the child re­
straint so that the safety belt will be prop­
erly pos it ioned.
- 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, CO player, electronic games de­
vice, power inverter or seat heater fo r
ch ild seats) . These may influence the elec­
trical capacitance measu red by the capac i­
tive passenger detec tion system and can
also fly around in an acc iden t and c ause
