2012 AUDI A8 control arm

Warm and cold Climate controls
Description
The climate control system warms, cools and
adds humidity to the a ir in the veh icle inter io r.
It is the most effect ive when the windows and
sunroof* are closed. If the temperature inside
the parked vehicle becomes very warm, open­
ing the window briefly will speed up the cool­
ing process.
I n all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has r eached a certain
temperature.
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.
Pollut ant filter
The po llutant filte r removes pollutants s uch
as dust and pollen from the air.
The air pollutants filte r must be changed at
the intervals spec ified in you r Wa rra nty
&
Maintenance book let, so that the air condi­
tioner can properly work.
I f you drive you r vehicle in an area with h igh
ai r po llution , the fi lter may need to be
changed more freq uent ly than specified in
your Aud i Warranty
& Ma intenance booklet. If
i n doubt, ask your authorized Audi Service Ad­
visor for advice .
K ey coded settings
The climate con trol settings are a utomat ica lly
stored and assigned to the remote contro l key
that is in use .
& WARNING
Reduced visibility is dangero us and can
cause accidents . -
Warm and cold 75
- For safe driving it is very important that
all windows be free of ice, snow and con­
densat ion.
- Comp letely fam iliarize yourse lf with the
proper use and funct ion of the heat ing
and ve nti lation system and especially
how to defog and defrost the w indows.
- Never use the windshield wiper/washer
system in freez ing weather unt il you
have warmed the w indshield first, using
the heating and ventilation system . The
washer solution may free ze o n the wind­
shie ld and red uce visib ility.
(D Note
- If you suspect that the air conditioner has been damaged, switch the system
off to avoid furt her damage and have it
i n spected by a q ua lified dea lership.
- Repairs to the Audi air conditioner re­
quire specia l techni cal know ledge and
special tools. Contact an autho rized Aud i
dealer fo r ass istance.
@ For the sake of the environment
By reduci ng the amou nt of f uel you use,
you also red uce the amount of pollutan ts
emitted into the air .
(D Tips
- Keep the air intake s lots ( in fro nt of the
w indshield) free from ice, snow and de­
br is in order to maintain the proper f unc ­
tion of the climate control system.
- T he energy management system may
switch the seat heating* or rear window
defroster off temporar i Ly . These systems
are available again as soon as the energy
balance has been restored .
- Air escapes through vents under the rear
window. When placing items of clothing
on the luggage compartment cover, en­
sure that the openings are not covered.

On the road 79
-Adjust the steering wheel column only
when the vehicle is not moving to pre­
vent loss of vehicle control.
- Adjust the driver 's seat or steering wheel
so that there is a minimum of 10 inches (25 cm) between your chest and the
steering wheel
~ page 125, fig . 133 . If
you cannot maintain th is m inimum dis­
tance, the airbag system cannot protect
you properly.
- If physical limitations prevent you from
sitt ing 10 inches (25 cm) or more from
the steering wheel, check with your au­
thorized Audi dealer to see if adaptive
equipment is available .
- If the steering wheel is al igned with yo ur
face, the supplementa l driver's airbag
cannot provide as much protection in an
accident. Always make sure that the
steering whee l is aligned with your
chest.
- Always hold the steering whee l with your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of personal injury
if the driver's airbag deploys.
- Never hold the steering wheel at the 12
o'clock position or with your hands inside

126 Driving Safely
• Always keep both feet in the footwell so
that you are in control of the vehicle at all
times.
For detailed information on how to adjust the
driver's seat, see
r:::> page 55.
A WARNING
Drivers who are unbelted, out of position
or too close to the airbag can be seriously
injured by an airbag as it unfolds. To help
reduce the risk of serious personal injury:
- Always adjust the driver's seat and the
steering wheel so that there are at least
10 inches (25 cm) between your breast­
bone and the steering wheel.
- Always adjust the driver's seat and the
steering wheel so that there are at least
4 inches (10 cm) between the knees and
the lower part of the instrument panel.
- Always hold the steering wheel on the
outside of the steering wheel rim with
your hands at the 9 o'clock and 3 o'clock positions to help reduce the risk of per­
sonal injury if the driver's airbag inflates.
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steering wheel
rim or on the steering wheel hub. Hold­
ing the steering wheel the wrong way
can cause serious injuries to the hands,
arms and head if the driver's airbag in­
flates.
- Pointing the steering wheel toward your
face decreases the ability of the supple­
mental driver's airbag to protect you in a
collision.
- Always sit in an upright position and nev­
er lean against or place any part of your
body too close to the area where the air­
bags are located.
- Before driving, always adjust the front
seats and head restraints properly and
make sure that all passengers are prop­
erly restrained.
- Never adjust the seats while the vehicle
is moving. Your seat may move unexpect- edly and you could lose control of the ve­
hicle .
- Never drive with the backrest reclined or
tilted far back! The farther the backrests
are tilted back, the greater the risk of in­
jury due to incorrect positioning of the safety belt and improper seating posi ­
tion .
- Children must always ride in child seats
r:::> page 166. Special precautions apply
when installing a child seat on the front passenger seat¢
page 142.
Proper seating position for the front
passenger
The proper front passenger seating position
is important for safe, relaxed driving .
For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the seat for the front
passenger to the following position :
• Adjust the angle of the seatback so that it is
in an upright position and your back comes in full contact with it whenever the vehicle is
moving.
• Adjust the head restraint so the upper edge
is as even as possible with the top of your
head. If that is not possibl e, try to adjust
the head restraint so that it is as close to
this position as possible¢
page 128.
• Keep both feet flat on the floor in front of
the front passenger seat .
• Fasten and wear safety belts correctly
r:::> page 13 7.
For detailed information on how to adjust the
front passenger's seat, see
r:::> page 54 .
A WARNING
-
Front seat passengers who are unbelted,
out of position or too close to the airbag
can be seriously injured or killed by the air­
bag as it unfolds. To help reduce the risk of
serious personal injury:

Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job , occupants must al­
ways properly wear their safety belts and be
in a proper seating position.
F or your safety and the safety of your passen­
gers, before driving off, always:
• Adjust the dr iver's seat and steering wheel
properly ¢
page 125,
• Adjust the front passenger's seat properly
r=;page 55,
• Wear safety be lts properly r=; page 13 7,
• Always properly use the proper child re-
stra int to protect children¢
page 166.
In a collision, airbags must inflate within the
blink of an eye and with considerable force .
The supplementa l airbags can cause injuries if
the dr iver or the front seat passenger is not
seated properly . Therefore in order to he lp the
a irbag to do its job, it is important, both as a
d river and as a passenger to sit properly at all
times.
By keeping room between your body and the
steering wheel and the front of the passenger
compartment, the airbag ca n inflate fully and
comp letely and provide supp lemental protec­
tion in certain frontal collisions¢
page 125,
Proper occupant seating positions .
For detai ls
on the operat ion of the seat adjustment con­
trols ¢
page 55.
It's especially important that children a re
properly restrained ¢
page 166.
There is a lot that the driver and the passen­
gers can and must do to help the individua l
safety features ins talled in your A udi work to­
gether as a system.
Prope r seat ing pos ition is important so that
the front airbag on the driver s ide can do i ts
job. If yo u have a physical impa irment or con- dition that prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reaching the peda ls , or if you
have concerns with regard to the function or
operation of the Advanced Airbag System,
please contact your author ized Audi dealer or
qualified workshop, or call Audi Customer Re­
lations at 1-800-822-2834 for poss ible modi­
ficat ions to your ve hicle.
When the airbag system deploys, a gas gener ­
ator will f il l the a irbags, break open t he pad­
ded cove rs, and i nflate between the steer ing
whee l and the dr iver and between the instru­
ment pane l and the front passenger. The a ir­
bags will deflate immediately after dep loy­
ment so that the front occupants can see
t h rough the windshie ld again witho ut inter­
ruption .
All of th is takes p lace in the b link of an eye, so
fast that many peop le don't even realize tha t
the airbags have deployed. The airbags a lso
inflate with a great dea l of force and nothing
shou ld be in their way when they deploy.
Front airbags in combination with properly
wor n safety belts slow down and lim it the oc ­
cupant's forward movement . T ogether they
help to prevent the drive r and front seat pas­
senger from hitting pa rts of the inside of the
vehicle while reducing the forces acting on the
occupant dur ing the crash . In this way they
help to reduce the risk of injury to the head
and upper body in the crash. A irbags do not
protect the arms or the lower parts of the
body.
Both front airbags wi ll not inflate in all fronta l
collisions . The t riggering of the airbag system
depends on the vehicle dece lerat ion rate
caused by the co llision and registered by the
electron ic control unit. If th is rate is below
the reference value programmed into the con ­
t rol unit , the airbags will not be trigge red,
even though the car may be badly damaged as
a res ult of the co llision . Ve hicl e damage, re­
pair costs or even the lack of ve hicle damage
is not necessari ly an indication of whether an
airbag shou ld inflate or not .
