\.J ' 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
sunroof* are closed. If there is a build-up of heat
inside the vehicle, ventilation 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 reached a sufficient tem­
perature .
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.

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 climate
contro l system, especially with the defrost­
ing and defogging function.
- When the temperature is below freezing,
only use the windshield washer system after
Warm and cold
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshield and impair visibili­ ty .
(D Note
-If you suspect that the climate control sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Audi dealer or authorized
Aud i Service Facility.
- Repairs to the Audi climate control system
require special technical knowledge and
special tools . See an authorized Aud i dealer
or authorized Audi Service Facility.
@ For the sake of the environment
-To save fuel, turn off cooling mode by press­
ing the
IAJCI button . This will also reduce
em iss ions.
- In vehicles w ith a diesel engine, you can
switch the auto supplementary heater off in
the Infotai nment system.
(D Tips
- To prevent interference with the heat ing
and cooling output and to prevent the win­
dows from fogging over, the air intake in
front of the windshie ld must be free of ice,
snow or leaves.
- Condensation from the cooling system can
dr ip 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 avai lable aga in as soon
as the energy supply has been restored.

\.J ' -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 ca pacita nee of the child safe­
ty seat and/or the person on the seat and
thus 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 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 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 child restraint, make
certain that the
PASSENGER AIR BAG OFF
light comes on and stays on whenever the
child restraint is installed 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.
.&_ WARNING
If the front passenger seat gets wet, dry it im­
mediately.
- If liquid soaks into the front passenger seat,
this can keep the airbag system from work­
ing properly and may, for instance, deacti­
vate the passenger frontal airbag.
If this
happens, the
PASSENGER AIR BAG OFF
light will come on and stay on together with
the airbag indicator light
fl (USA models) I
Airbag system
E,I (Canada models) in the instrument clus­
ter.
- If liquid is pooled on the seat, but has not
soaked in, this may also keep the airbag sys­
tem from working properly and cause the
passenger frontal airbag to be enabled
(turned on), even though there is a properly
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 passenger frontal airbag is turned on,
the
PASSENGER AIR BAG OFF light light
will go out.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side
airbags supplement the protection offered by the
front three-point safety belts with pretensioners
and load limiters and the adjustable head re­
straints* to help reduce the risk of injury in a
wide range of accident and crash situations. Be
sure to read the important information about
safety and heed the WARNINGS in this chapter.
Deployment of the Adv a need Airbag System and
the activation of the safety belt pretensioners de­
pend on the deceleration measured by the crash
sensors and registered by the electronic control
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, regardless of safety belt
use, the front passenger frontal airbag will be
turned off if the electrical capacitance measured by the capacitive passenger detection system on
the front passenger seat is less than the amount
programmed in the electronic control unit . The
front passenger frontal airbag will 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 when the front Ad­
vanced Airbag System on the passenger side has been turned

\.J ' 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
PA SSEN ­
GER AIR BAG OFF
light does not come on
and stay on, immediately insta ll 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 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 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 side airbag.
- 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.
Ch ild safety
-Never put the forward-facing 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
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, befo re 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 wi ll 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.
- Never place objects on the seat (such as a
laptop, CD player, electronic games de­
vice, power inverter or seat heater for
ch ild seats) . These may influence the elec­
trical capacitance measured by the capac i­
tive passenger detection system and can
also fly around in an acc ident 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 insta ll any child restraint sys­
tem on this seat.
- Make sure that there are no wet objects
(such as a wet towe l) and no water or oth­
