156 Airbag sys te m
If the tota l electrical capacitance registe red
on the front passenger seat is more than that
of a typ ica l 1 year-old, but less than the
weight of a small adult, the front a irbag on
the passenger side may deploy (the
PA SSE N­
GER AIR BAG OFF
li ght does not come on).
For e xample , the airbag m ay deploy if :
-a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the chi ld seats listed
¢ page 177),
-a chi ld who has outgrown child restraints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light in the center
of the instrument panel wi ll come on and stay
on.
If the front passenger airbag deploys, the
F ederal Standard requires the airbag to meet
the " low risk" deployment criteria to help re­
d uce the risk of injury through interaction
with the airbag. "Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the electronic control un it
¢ page 161.
Alw ays rem ember : Even though your vehicle
is equipped with Advanced Airbags, the safest
place for children is properly restrained on the
back seat . Please be sure to read the impor­
tant information in the sect ions that follow
and be sure to heed a ll of the WARNINGS.
.&_ WARNING
To reduce the risk of injury when an airbag
inflates, a lways wear safety belts prope rly.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of position in any
way, your risk of injury is much higher.
- You w ill also receive serio us injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in ­
flates - even with an Advanced Airbag
¢page 149.
.&_ WARNING
A child in a rearward-fac ing ch ild 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
van ced A irbag System.
- Altho ugh the Advanced Airbag System in
your veh icle is designed to turn off the
front airbag when a rearward-facing
child restraint has been instal led on the
front passenger seat, nobody can abso ­
lutely g uarantee that dep loyment is im­
possible in all conceivable situations that
may happen dur ing the usefu l life of your
veh icle.
- The inflating airbag will h it 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 rearward-facing ch ild re­
straints on the rear seat .
- If you must install a rearward fac ing
child seat on the front passenger seat because of exceptional circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immed i­
a tely insta ll the rear-facing child seat in a
rear seat ing pos ition and have the airbag
system inspected by your Audi dealer.
.&_ WARNING ,..___
If, in except iona l circumstances, you m ust
install a forward -facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and s ide a irbag.
- Never p ut the forward-facing child re­
straint up against or very near the instru­
ment panel.
- Always move the passenger seat into its
rearmost pos ition in the seat's fore and
aft ad justment range, as far away from
the airbag as possible, before install ing
the forward-fac ing ch ild restra int. The
-

backrest must be adjusted to an upright
posit ion.
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenger detection
system in the seat to s ignal to the A irbag
System that the seat is occupied by a person when it is not, or to signa l that it
is occupied by som eone who is heavier
than t he pe rson actually s itting on t he
sea t. T he presence of addition al obje cts
cou ld cause the passenger front airbag
to be t urned on when it sho uld be off, or
cou ld cause t he airbag to work in a way
that is different from the way it wou ld
have worked without the object on the
seat.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime w henever the ignition is switc hed
on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
A irbag System in it. These parts incl ude t he
c a pac itive passenger de te ct ion sys tem, wir­
ing, b racke ts, and more . The cont ro l uni t
monitors the system o n the front passenger
seat when the ign ition is switched on and
turns the airbag indicator light on w hen a
malfunct ion in the one of the system compo­
nents is detected ¢
page 162. Because the
fro nt passenge r seat contains important parts
of the Advanced Airbag System, you must
take care to p revent it from bei ng damaged.
D amage to the seat may preven t the Ad ­
vanced A irbag System for the front passenger
seat from doing its job in a crash .
The front Advanced Airbag System
consists of the following:
-Crash sensors in the front of the veh icle tha t
measure ve hicle acceleration/dece le ration
to provide information to the Advanced Air­ bag System about the severity of the crash.
A irbag system 157
- An elect ron ic contro l unit, with integrated
crash sensors fo r front and side impacts .
T he control un it "decides" whether to f ire
the front a irbag s based on the informat ion
received from the crash sensors. The control
unit also "decides" whether the safety belt
prete nsione rs should be act iva ted .
- An Advanced A irbag w it h gas generator and
cont ro l valve for the driver ins ide the steer ­
ing wheel h ub.
- An Advanced A irbag w ith gas generator and
cont ro l valve inside the instrument pa nel for
the front passenger .
- A capacit ive passenger detection system un ­
de rneath the front passenger seat cover .
This system measu res the ele ct rical capac i­
t ance of the perso n in the seat. The informa ­
t ion regis tered is se nt cont inuo usly to the
elec tronic con trol un it to regu late dep loy­
ment of the front Advanced A irbag on the
passenger side.
-An airbag monitoring system an d ind icator

formation registered is sent cont inuo usly to
the electron ic contro l unit to regulate de­
ployment of the front Adva need A irbags .
- The
PASSENGER AIR BAG OFF li ght comes

light light will go out.
How the Advanced Airbag System
components work together
The fron t Advanced Airbag System and the
side airbags supplement the protection of­
fered by the front three -point safety be lts
with p retensioners and load limiters and the
adjustab le 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 impor­
tant information about safety and heed the
WARNINGS in this chapter .
Dep loyment of the Advanced Airbag System
and the act ivation of the safety be lt preten­
sioners depend on the dece lerat ion measured
by the crash sensors and registered by the
e lectronic control un it. The amount of infla­
tion of the front airbags can also be adapted to the front seat posi tion, depend ing on the
d istance between the respective front seat
and the steering whee l or instrument panel as
registe red by sensors in the seats. Crash se­
verity depends on speed and deceleration as
well as the mass and stiffness of the vehicle
or object involved in the crash .
On the passenger s ide, regard less of safety
be lt use, the front passenger f ronta l airbag
will be turned off if the electrical capacitance
measured by the capac itive passenger detec­
tion system on the front passenger seat is less
tha n the amount programmed in the electron­
ic control unit. The front passenger fronta l air­
bag will a lso be turned off if the capa cita nce
measured by the system for the front pa ssen­
ger seat equa ls t hat of an infant of abo ut one
yea r of age in one o f the child seats that was
used to cert ify the Advanced Airbag System
under Federal Motor Vehicle Safety Standard

- If you are unrestra ined, leaning forward,
sitt ing s ideways or o ut of pos ition in any
way, your ris k of injury is m uc h higher.
- You will a lso receive serious injuries and
co uld even be killed if yo u are up aga inst

More important things to know about
front airbags
Fi g. 16 3 In flated front a irbags
Safety belts a re important to he lp keep front
seat occupants in the proper seated position
so that ai rbags can unfold p roper ly and pro­
v ide s upplement al pro tect ion in a fron tal col­
lis ion .
T he front airbags a re des igned to provide ad­
di tional protection fo r the chest and fa ce of
the driver a nd the front seat p assenger when :
- safety belts are worn properly,
- the seats have been positioned so that the
occupant is properly seated as far as poss i­
b le from th e airbag,
- and the head restraints have been properly adjusted .
Because 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 cou ld become dan ­
gerous p ro jecti les, and be pushed in to you if
t h e a irbag inf lates.
When an airbag deploys, fine dust is re leased.
This is norma l and is not caused by a fire i n .,,.

-Never place or attach accessories or o th ­
er objects (such as cup hol ders, tele­
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 a reas and yourself. These
objects co uld cause injury in a crash, es­
pecially when the airbags inflate .
- Never recline the front passenger's seat
to transport objec ts. Items can also
move into the area o f the side airbag or
the front airbag during braking or in a
sudden maneuver . Objects near the air­
bags can become project iles and cause
injury, part icularly when the seat is re­
cl ined .
- Never place or transport ob jects on the
front passenger seat. Objects on the
front passenger seat could cause the ca­ pacitive senso r in the seat to s ignal to
airbag system that the seat is occupied
by a person when it in fa ct is not, o r that
the person on the se at is he avier than he
or she actually is. The change in electric
capacitance beca use of such objects can
cause the passenger front airbag to be
turned on when it sho uld be
off, or can
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout objects on the seat.
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenge r detection
system in the s eat to s ignal to the A irbag
System that the seat is oc cupied by a
pers on when it is not, or to sign al that it
is occupied by someone who is heavier
than the pe rson actually s itting on the
seat . The presence of an object co uld
cause the passenger front a irbag to be

A WARNING
The fine dust created when airbags deploy
can cause breathing prob lems fo r people
with a history of as thma or other breath­

- To reduce the risk of breath ing problems,
those wi th asthma o r other respiratory
conditions s hou ld get fresh air r ight

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.
Airbag system 165
- 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

168 Airbag system
How knee airbags work
Applies to vehicles: with knee airbags
The risk of injury to the leg area can be re­
duced by fully inflated knee airbags.
Fig. 166 Inflated airbags protecting in a frontal colli·
s io n
The knee airbag system has been designed so
that the a irbags for the driver and front pas­
senger deploy in certain but not all frontal
coll isions.
If the front airbags deploy, the knee airbags
a lso deploy in frontal collisions when the de­
ployment threshold stored in the control unit
is met .
When the system deploys, the airbags fill
with a propellant gas, and inflate between the
lower part of the instrument panel and the
driver and the lower part of the instrument
panel and the front passenger
Q page 159,
fig . 163.
Although they are not a soft pillow, they can
"cush ion" the impact and in this way they can
help to reduce the risk of injury to the lower
extremities.
All of this takes place in the blink of an eye, so
fast that many people don 't even realize that
the airbags have deployed . The airbags also
inflate with a great deal of force and it is im­
portant for occupant safety that noth ing
should be in their way when they deploy.
Fully inflated airbags in combination with
properly worn safety belts slow down and lim­
it the occupant's forward movement and help
to reduce the risk of injury. Important safety instructions on the
knee airbag system
Applies
to vehicles: with knee airbags
Airbags are only supplemental restraints. Al­
ways wear safety belts correctly and ride in a
proper seating position .
There is a lot that you and your passengers
must know and do to help the safety belts and
airbags to provide supplementa l protect ion.
A WARNING
-An inflating knee airbag can cause serious
i n jury. Wearing safety belts incorrectly and
improper seat ing positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you are seated too close
to any of the airbag locations. When ad­
justing their seat pos itions, it is impor­
tant that both the driver and the front passenger keep the ir upper bodies and
knees at the following m inimum safe
distances :
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru­
ment panel.
- at least 4 inches (10 cm) between the knees and the lower part of the instru­
ment panel.
- The risk of personal injury increases if
you lean forward or to the side, or if the
seat is improperly positioned and you are
not wearing your safety belt . The risk in­
creases even more should the airbag de­
p loy .
- Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of inju ry in an accident by inter­
fering w ith the way the airbag deploys or
by being pushed into you as the airbag
deploys.
- Never let anybody, espec ially children
or animals ride in the footwell in front

-Always read and heed all WARNINGS
whenever using a child restraint in ave­
hicle

¢ page 149, Airbag system and
¢ page 175, Important things to
know.
(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Ad­
vanced Airbag System" in compliance with United States Federal Motor Vehicle Safety
Standard (FMVSS) 208 as applicable at the
time your vehicle was manufactured .
T he Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re­
quirements for 3-and 6-year old children on
the passenger side and small adults on the
driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the airbag that can
occur, for example , by being too close to the
steering wheel and instrument panel when
the airbag inflates . In addition, the system
has been certified to comply with the "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front passenger seat in child restraints that are list­
ed in the Standard .
Even though your vehicle is equipped with an
Advanced Airbag system, all children, espe­
cially those 12 years and younger, should al­
ways ride in the back seat properly restrained
for their age and size. The airbag on the pas­
senger side makes the front seat a potentially
dangerous place for a child to ride. The front
seat is not the safest place fo r a child in a for­
ward-facing child safety seat. It can be a very
Child Safety 177
dangerous place for an infant or a larger child
in a rearward-facing seat.
The vehicle's Advanced Airbag System has a
capacitive passenger detection system in the
front passenger seat cushion that can detect
the presence of a baby or a child in a child re­
straint system on this seat.
The capacitive passenger detection system
registers the changes that result in an electri ­
cal field when a child, a child restraint, and a
baby blanket are on the front passenger seat .
The change in the measured capacitance due
to the presence of a child, a child restraint,
and a baby blanket on the front passenger
seat is related to the child restraint system resting on the seat . The measured capacitance
of a child restraint system varies depending
on the type of system and specific make and
model.
The electrical capacitance of the various
types, makes, and models of child restraints
specified by the U.S.National Highway Traffic
Safety Administration (NH TSA) in the relevant
safety standard are stored in the Advanced
Airbag System control unit together with the capacitances typical of infants and a 1-year
old child. When a child restraint is used on the
front passenger seat with a typical 1 year-old infant, the Advanced Airbag System compares
the capacitance measured by the capacitive passenger detection system with the data
stored in the electronic control unit.
Child restraints and Advanced front
airbag system
Regardless of the child restraint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu­
facturer for use with an airbag. Always be sure
that the child restraint is properly installed at
one of the rear seating positions. If in excep­
tional circumstances you must use it on the
front passenger seat, ca refully read all of the
information on child safety and Advanced Air-
bags and heed all of the applicable ..,.
