-Always carefully follow instru ctions from
c hild restraint manufacturers when in
sta lling child restraints.
A WARNING
If, in exceptional circumstances, you must
install a forward or rearward-facing child
restraint on the front passenger's seat:
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec
tion.
- An improperly installed child restraint
can interfere with the airbag as it de
ploys and seriously injure or even kill the
child - even with an Advanced Airbag
System.
- Always carefully follow the manufactur
er's instructions provided with the child
seat or carrier .
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenger detection
system in the seat to signal to the Airbag
System that the seat is occupied by a
person when it is not, or to signal that it
is occupied by someone who is heavier
than the person actually sitting on the
seat. The presence of additional objects
could cause the passenger front airbag
to be turned on when it should be off, or
could cause the airbag to work in a way
that is different from the way it would
have worked without the object on the
seat .

Front airbags
Description of front airbags
The airbag system can provide supplemental
protection to properly restrained front seat occupants.
Fig. 157 Loc ation of driver airbag: in steering w heel
Fig. 158 Loc ation of front passenger's a irbag: in the in·
strument panel
Your vehicle is equipped with an "Advanced
Airbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicable at the time your
vehicle was manufactured. The system senses
the position of the front seats and controls
front airbag inflation with a valve, depending
on the distance between the respective seat
and the steering wheel or instrument panel.
The safety belts for the seats have "preten
sioners" that help to take slack out of the belt
system. The pretens ioners are also activated
by the electronic control unit for the airbag
system .
The front safety belts also have load limiters
to help reduce the forces applied to the body
in a crash.
The airbag for the driver is in the steering
wheel hub
q fig. 157 and the airbag for the
front passenger is in the instrument panel
-The Advanced Airbag System can deploy
in accordance with the .,low risk" option
for 3- and 6-year-old children under the U.S. Federal Standard if a child with elec
trical capacitance greater than the com bined capacitance of a typical one-year
old infant restrained in one of the for
ward facing or rearward-facing child seats with which your vehicle was certi
fied is on the front passenger seat and
the other conditions for airbag deploy ment are met.
- Accident statistics have shown that chil
dren are generally safer in the rear seat
area than in the front seating position.
- For their own safety, all children, espe
cially 12 years and younger, should al
ways ride in the back properly restrained
for their age and size.
Advanced front airbag system
Your vehicle is equipped with a front Advanced
Airbag System in compliance with United
States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was manufactured.
The front Advanced Airbag System supple ments the safety belts to provide additional
protection for the driver's and front passeng
er's heads and upper bodies in frontal crashes.
The airbags inflate only in frontal impacts
when the vehicle deceleration is high enough.
The front Advanced Airbag System for the
front seat occupants is not a substitute for
your safety belts. Rather, it is part of the over all occupant restraint system in your vehicle.
Always remember that the airbag system can
only help to protect you, if you are sitting up right, wearing your safety belt and wearing it
properly . This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be .
The 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 very small adults on
Airbag system 153
the driver side. The low risk deployment crite
ria are intended to help reduce the risk of in
jury through interaction with the front 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 "suppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are restrained on the front passenger
seat in child restraints that are listed in the
Standard
¢ page 175, Child restraints and
Advanced front airbag system.
"Suppression " requires the front airbag on the
passenger side to be turned off if:
- a child up to about one year of age is re
strained on the front passenger seat in one
of the rear-facing or forward-facing infant
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad
vanced Airbag System in your vehicle was
certified. For a listing of the child restraints
that were used to certify your vehicle's com
pliance with the US Safety Standard
¢page 175,
-When a person is detected on the front pas
senger seat that has an electrical capaci
tance that is more than the total electrical
capacitance of a child that is about 1 year
old restrained in one of the rear-facing or
forward -facing infant restraints (listed in
Federal Motor Vehicle Safety Standard 208
with which the Advanced Airbag System in
your vehicle was certified), the front airbag on the passenger side may or may not de
ploy.
The
PASSENGER AIR BAG OFF light comes on
when the electronic control unit detects a to
tal electrical capacitance on the front passen
ger seat that requires the front airbag to be
turned off. If the
PASSENGER AIR BAG OFF
light does not come on, the front airbag on
the passenger side has not been turned off by
the control unit and can deploy if the control unit senses an impact that meets the condi -
tions stored in its memory .

154 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 175),
-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 159.
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 147.
.&_ 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 upri ght
posit ion.
- Always make sure that t here 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 signal that it
is occupied by som eone who is heavier
than t he pe rson actually s itting on the
seat. The presence of additiona l 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 whenever 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 the
capac 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 when a
malfunct ion in the one of the system compo
nents is detected ¢
page 160. 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 that
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 15 5
- An electron 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
pretens ione rs should be act iva ted .
- An Advanced A irbag w it h gas genera tor 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 panel for
the front passenger .
- A capacit ive passenger detection system un
derneath 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 registered is se nt cont inuo usly to the
elec tronic con trol un it to regu late dep loy
ment of the front Advanced Ai rbag on the
passenger side.
-An airbag monitoring system and ind icator
light in the instr ument cluster ¢

-A senso r in each front seat registers the dis
tance between the respective seat a nd the
steering whee l or instrument panel. The in
formation reg istered 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
on and stays on in the center of the instr u

things on the seat cushion can have the
same effect. If the front passenger fron
tal airbag is turned on, the
PASSENGER

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
208. The

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

- 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 passe nger'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

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 163
- 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
