154 Airbag system
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side airbags supplement the protection of
fered by the front three-point saf ety be lts
with pretensioners and load limiters and the
adjus table head restr aints* to help reduce the
risk of injury in a wide range of acc ident and
crash situat ions. Be sure to read the impor
tant information about safety and heed the
WARNINGS in this chapter .
Deployment of the Advanced Airbag System
and the activat ion of the safety belt preten
sioners depend on the decelerat ion measured
by the crash senso rs and regis tered by the
e lectronic control u nit. Crash sever ity depends
on speed and deceleration as well as the mass
and stiffness of the vehicle or object involved
in the crash.
On the passenger side, regard less of safety
be lt use, the front passenger fronta l airbag
will be turned off i f the e lectrical capac itance
measured by the capacitive passenger detec
tion system on the front passenge r seat is less
than the amount programmed in the electron ic control unit. The front passenger frontal air
bag will also be turned off if the capacitance
measured by the system for the front passen
ge r seat equa ls that of an infant of abo ut one
yea r of age i n one of the child sea ts that was
used to cer tify the Advanced Airbag System
under Federal Motor Vehicle Safety Standard
208 . The
PASSENGER AIR BAG OF F light
comes on and stays on to tell you when the
front Advanced A irbag System on the passen
ger s ide has been turned off¢

A WARNING
To reduce the risk of injury when a n airbag
inflates, a lways wear safety belts properly .
- If you are unrestrained, leaning forward,
sitting sideways or out of position in any
way, your risk of inj ury is much higher.
- You wi ll also receive serious injuries and
could even be killed if you are up against
the a irbag or too close to it when it in- flates
-even w ith an Advanced A irbag

Safety be lts are important to he lp keep front
seat occupants in the proper seated position
so that a irbags can unfold proper ly and pro
vide supplemental protect ion in a frontal col
lis ion .
The front airbags are designed to provide ad ditional protection for the chest and face of
the driver and the front seat passenger when :
- safety belts are worn proper ly,
- the seats have been positioned so that the
occupant is properly seated as far as poss i
b le from the airbag ,
- and for ad justab le head restraints : the head
restraints have been properly adj usted .
Bec ause airbags inflate in the bli nk of an eye
with great force, th ings you have on your lap
or have p laced on the seat co uld become dan
gerous pro jecti les, and be p ushed into you if
the a irbag inf lates .
When an airbag deploys, fine dust is re leased.
T his is no rma l and is not caused by a fi re in
the vehicle . This dust is made up mostly of a
powder used to lubricate the airbags as they
deploy . It could irr itate skin .
It is important to remembe r that while the
supplementa l airbag system is designed to re
duce the like lihood of serious injur ies, other
injur ies, for examp le swelling, bruising and
minor abrasions, can also happen when air-
bags inflate . A irbags do not protect the arms

or the lower parts of the body. Front airbags
supp lement the three-point safety belts only
in some frontal collisions in which the vehicle
dece leration is high enough to deploy the air
bags.
F ront airbag s will no t deplo y:
- if the ignition is switched off when a crash
occurs,
- in side collisions,
- in rear-end collisions,
- in rollovers,
- when the crash deceleration measured by
the a irbag system is less than the m inimum
threshold needed for airbag deployment as
registered by the electronic control unit.
The f ront pas seng er airbag al so will n ot
deploy:
- when the front passenger seat is not occu
pied,
- when the electrical capac itance measured by
the capacitive passenger detect io n system
for the front passenger seat indicates that
the passenger side frontal airbag must be
switched off by the electronic control unit
(the
P AS SENGER A IR BA G OFF light
Q page 157 and how they work comes on
and stays on).
A WARNING
Sitting in the wrong position can increase
the risk of serious injury in crashes.
- To reduce the r isk of injury when the air
bags inflate, the driver and passengers
must always sit in an upright posit ion,
must not lean against or place any part
of the ir body too close to the area where
the a irbags are located.
- Occupants who a re unbelted, out of posi
t ion or too close to the airbag can be se
riously injured by an airbag as it unfolds
with great force in the blink of an eye
Qpage 146 .
A WARNING
A child in a rearward-facing child seat in
stalled on the front passenger seat will be

seriously injured and can be killed if the
front airbag inflates -even w ith an Ad
vanced A irbag System.
- The inflating airbag will hit the ch ild seat
or infant carrier with great force and will
smash the child seat and child against
the backrest, center armrest, door or roof.
- Always install rear-fac ing ch ild seats on
the rear seat.
- If you must install a rearward fac ing
child safety seat on the front passenger
seat because of exceptional c ircumstan
ces and the
PASSENGER AIR BAG OFF
light does not come on and s tay on, im
mediately install the rearward-fac ing
child safety seat in a rear seating posi
tion and have the airbag system inspect
ed by your authorized Audi dealer.
A WARNING
Objects between you and the airbag will increase the r isk of injury in a crash by in
terfering with the way the airbag unfolds
or by be ing pushed into you as the airbag
inflates.
- Never hold things in your hands or on
your lap when the veh icle is in use.
- Never transport items on or in the area
of the front passenger seat. Objects
could move into the area of the front air
bags during braking or other sudden ma
neuvers and become dangerous projec
tiles that can cause ser ious personal in
jury i f the a irbags inflate.
- Never p lace or a ttach accesso ries o r oth
er objects (such as cup holders, te le
phone brackets, large, heavy or bulky ob
jects) on the doors, over or near the area marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be
tween those areas and yourself. These objects could cause injury in a crash, es pecially when the airbags inflate.
- Never recline the front passenger 's seat

Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and that dis
carded components do not cause injury or pol lute the environment.
A WARNING
Improper care, servicing and repair proce
dures can increase the risk of personal in
jury and death by preventing an airbag from deploying when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the material so that the airbag cannot de
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru
ment panel, front seats or electrical sys
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc .) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work
shop. -
Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace
ment upholstery over the front seat
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can deploy only once.
After an airbag has been deployed, it must be replaced with new replacement
parts designed and approved especially
for your Audi model version. Replace
ment of complete airbag systems or air
bag components must be performed by
qualified workshops only . Make sure that
any airbag service action is entered in
your Audi Warranty
& Maintenance book
let under
AIRBAG REPLACEMENT RE
CORD.
- For safety reasons in severe accidents,
the alternator and starter are separated
from the vehicle battery with a pyrotech nic circuit interrupter.
- Work on the pyrotechnic circuit inter
rupter must only be performed by a
qualified technicians who have the ex perience, information and special tools
necessary to perform the work safely.
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre
cautions must be followed.

The inflatable side curtain airbags are located
on both sides of the interior above th e front
and rear side windows . T hey are identified by
the word "AIRBAG" on the windsh ield frame
and the center roof pillar.
The side curtain airbags contain features that prov ide ejection m itigation to he lp prevent ve
h icle oc cupant s or parts of their bodies from
being comple tely or partially ejected from the
vehicle interior in certain side impacts and ve
h icle rollovers .
The s ide curtain airbag system supp lements
the safety belts and can help to reduce the risk of injury for occupa nts ' heads and upper
torso on the side of the veh icle that is struck
i n a side collision . T he side curta in a irbag in
flates in s ide impacts and on ly w hen the veh i
cle acce le rat ion reg iste red by the cont ro l u nit
is high enough . If this rate is below the refer
ence value programmed into t he control unit,
the side c urtain airbag will not be t riggered,
even though the car may be badly damaged as
a result of the collision. It is not possible to
define an airbag triggering range tha t will
cover every possible angle of impact, since the
circumstances will vary considerably between
one co llision and another. Important factors
i nclude, for examp le, the natu re (hard o r soft)
of the impacting object, the ang le o f impact ,
ve hicl e speed, et c.
q page 168, How sid e cur
tain airbags work .
Besides their normal safety f unction, safety
be lts work to help keep the dr iver or front
passenger in position in the event of a frontal
collision so that the side curtain airbags can provide protection.
The airbag system is not a s ubst itute for yo ur
safety be lt . Rathe r, it is pa rt of the overall oc
cupant restraint system in your vehicle . Al
ways rememb er that the airbag system can
only help to protect you if you are wearing
your safety belt and wear ing it properly. Th is
is another reason why you shou ld always wear
your safety belts, not just because the law re
q uir es you to do so

Airbag system 167
It is important to remembe r that wh ile the
side curtain airbag system is designed to help
reduce the likelihood of ser ious injuries, other
injur ies, for example, swelling, bru is ing, fric
tion burns and minor abras ions can also be as
sociated w ith these airbags upon deployment .
Remember too , these airbags will deploy only
once a nd only in ce rtain kinds of accide nts -
you r safety be lts a re a lways the re to offer p ro

The side curtain airbag system basically
consists of:
-The e lectronic control module and external
side impact sensors
- The side curta in a irbags above the front and
rear s ide windows w it h ejection mitigation
featu res
- The a irbag indicator light in the instr ument
p ane l
The airbag system is mon itored e lectronically
to make ce rtain it is func tioning prope rly at all
times. Each time you sw itch on the ig nition,
the air bag system indicator light will come on
f o r a few se conds (sel f diagnos tic s) .
The side curtain airbag is not activat ed:
- if the ignition is sw itched off,
- in side collisions whe n the acceleration
measured by the sensor is too low,
- in rear-end collisions.
A WARNING
-Safety belts and the airbag system will
only provide pro tection when occupa nts
are in the proper seating position
q page 57, Front seats .
-If the ai rbag ind icator light q page 21
comes when the veh icle is being used,
have the system inspected imme diately

Child Safety
Important things to
know
Introduction
The rear seat is generally the safest place in a
collision.
The physical principles of what happens when
your veh icle is in a crash app ly also to chi ldren
¢ page 136, What happens to occupants not
wearing safety belts?.
But unlike adults and
teenagers, their muscles and bones are not
fu lly developed. In many respects children are
at greater risk of serious injury in crashes than
adults.
Because children's bodies are not fully deve l
oped, they require restraint systems especial
ly designed for their size, weight, and body
structure. Many countries and all states of the
United States and provinces of Canada have
laws requiring the use of approved child re
straint systems for infants and small ch ildren.
In a fronta l crash at a speed of 20 -35 mph
(30-56 km/h) the forces acting on a 13-pound
(6 kg) infant w ill be more than 20 t imes the
weight of the child. This means the weight of
the child would suddenly be more than 260 pounds (120 kg). Under these conditions,
only an appropriate ch ild restraint properly
used can reduce the risk of ser ious injury.
Child restraints, like adult safety belts, must
be used properly to be effective. Used improp
erly, they can increase the risk of serious in
jury in an accident.
Consult the child safety seat manufacturer's instructions to be sure the seat is right for
your child's size¢
page 174, Important safe
ty instructions for using child safety seats.
Please be sure to read and heed all of the im
portant information and WARNINGS about
ch ild safety, Advanced Airbags, and the instal
l ation of chi ld restraints in this chapter.
There is a lot you need to know about the Ad
vanced Airbags in your vehicle and how they
work when infants and children in child re- straints are on the front passenger seat
. Be
cause of the large amount of important infor
mation, we cannot repeat it all here . We urge
you to read the detailed information in this
owner's manual about airbags and the Ad
vanced Airbag System in your vehicle and the
very important information about transport
ing children on the front passenger seat.
Please be sure to heed the WARNINGS - they
are extremely important for your safety and
the safety of your passengers, especially in
fants and small children.
A WARNING
-Accident statistics have shown that chil
dren are generally safer in the rear seat
area than in the front seating position.
Always restrain any child age 12 and un
der in the rear.
- All vehicle occupants and especially chil
dren must be restrained properly when
ever riding in a vehicle. An unrestrained
or improperly restrained chi ld could be
injured by str iking the i nterior or by be
ing ejected from the vehicle during a
sudden maneuver or impact. An unre
strained or improperly restrained chi ld is
also at greater risk of injury or death
through contact with an inflating airbag.
- A suitable chi ld restraint properly instal
led and used at one of the rear seating positions provides the highest degree of
protection for infants and small children
in most accident situations.
A WARNING ,_
Children on the front seat of any car even
with Advanced Airbags can be ser iously in
jured or even killed when an airbag in
flates. A child in a rearward-facing child
safety seat installed on the front passen
ger seat will be seriously injured and can
be killed if the front airbag inflates.
- 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, or door.

-Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat in exceptional circumstances and
the
PASSENGER AIR BAG OFF light does
not come on and stay on, immediately
install the rear-facing child safety seat in
a rear seating position and have the air
bag system inspected immediately by
your Audi dealer.
_& WARNING
- Forward-facing child safety seats instal
led on the front passenger's seat may in
terfere with the deployment of the air
bag and cause serious 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 follow ing special precautions to be taken:
- Always make sure that the forward-fac
ing seat has been designed and certi
fied by its manufacturer for use on a
front passenger seat with a front and
side airbag.
- Always carefully follow the manufac
turer'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 in
structions require the top tether strap
to be used.
- Never put the forward-facing child re
straint up against or very near the in
strument panel.
- Always set the safety belt upper an
chorage to the adjustment position
that permits proper installation in ac
cordance with the child restraint manu
facturer's instructions.
- Always move the passenger seat into its rearmost position in the seat's fore
and aft adjustment range, as far away
from the airbag as possible before in-
Child Safety 1 71
stalling the child restraint. The back
rest must be adjusted to an upright po
sition.
- Always make sure that nothing pre
vents 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 device, power inverter or seat
heater for child seats) . These may in
fluence the electrical capacitance
measured by the capacitive passenger
detection system and can also fly
around in an accident and cause serious personal injury.
- Never place or use any electrical device
(such as a laptop, CO player, electronic
games device, power inverter or seat
heater for child seats) on the front pas
senger 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 passen ger seat, never install any child re
straint system on this seat.
- 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 .
- Always make sure that the
PASSENGER
AIR BAG OFF
light comes on and stays
on all the time whenever the ignition is
switched on.
- If the PASSENGER AIR BAG OFF light
does not come on and stay on, immedi
ately install the rearward-facing child
safety seat in a rear seating position
and have the airbag system inspected by your authorized Audi dealer.
- Always buckle the child seat firmly in
place even if a child is not sitting in it.
A loose child seat can fly around during
a sudden stop or in a collision.
- Always read and heed all WARNINGS
whenever using a child restraint in ave-
