116 Airbag sys te m
States Federal Motor Vehicle Safety Standard
208 as applicable at the time your vehicle was manufactured .
The front Advanced Airbag Sys tem supp le
ments the safety belts to provide additional
protection for the driver's and front passeng
er 's heads and upper bodies in fronta l crashes.
The airbags inflate only in fronta l impacts
when the vehicle dece lerat ion 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 veh icle.
A lways remember that the airbag system ca n
only help to protect you, if you are s itting up
right, wearing yo ur safety belt and wea ring it
p roperly. This is why you and you r passenge rs
must always be properly restr ained , not just
beca use the law requires you to be.
The Advanced Airbag System i n your veh icle
has been cer tified to meet the " low r is k " re
qu iremen ts for
3 an d 6 year-o ld childre n on
the passenger side and very small adu lts on
the driver side. The low risk deploymen t crite
ria are intended to he lp red uce the risk of in
jury through interaction with the front airbag that can occur, for example, by be ing too
close to the steer ing whee l and instrument
panel when the airbag i nflates .
In addition, the system has been certif ied to
comp ly w ith the "suppression" requ irements
of the Safety Standard, to tur n off the front
a irbag for infants
12 months old and younger
who a re restra ined on the front passenger
seat in c hild restra ints that a re listed in the
St anda rd ¢
page 134, Child restraints and
Advanced Airbags.
"Suppression" requires the front airbag on the passenger side to be turned off if :
- a ch ild up to about one year of age is re
stra ined on the front passenger seat in one
of the rear-facing or forwa rd-fac ing infa nt
rest raints listed in Federa l Motor Veh icle
Safety Standard 208 wit h whi ch the Ad
vanced Airbag System in your vehicle w as
certified . For a list ing of the child rest rain ts t
ha t were used to certify your vehicle 's com
pliance with the US Safety Standa rd
¢ page 134,
- weight less than a thres ho ld level stored in
the control unit is detected on the front pas
senger seat.
When a person is dete cted on the front pas
senger seat, weighing more than the tota l
weight of a chi ld that is about
1 year old re
stra ined in one of the rear-facing or forward
facing infant restraints ( listed in Federal Mo
tor Vehicle Safety Standard 208 w it h which
the Advanced Airbag System in your vehicle
was ce rtified), the front airbag on the passen
ger side may or may not deploy.
The
PASSENGER AIR BAG OFF light comes on
whe n the electro nic con trol unit detects a to
ta l we ight on the front passenger seat that re
quires t he front airbag to be tu rned off. If t he
PASSENGER AIR BAG OFF ligh t does no t
come o n, the fron t airbag on the passenger
s ide has not been turne d off by the cont ro l
u nit and can dep loy if the control unit senses
an impact that meets the conditions stored in
its memory.
If the total weight on the front passenge r
seat is more than that of a typica l
1 year-old,
but less than the we ight of a small ad ult, the
front a irbag on the passenger side may dep loy
(the
PASSENGER AIR BAG OFF light does not
come on).
For example , the airbag may deploy if:
- a small ch ild that is heav ier t han a typic al 1
yea r-old ch ild is on the front passenger seat
(regard less of whethe r the child is in one of
the child safety seats listed
¢ page 134),
-a child who has outgrown ch ild restraints is
on the front passenge r seat .
If the fron t passenger a irbag is turned off, the
PASSENGER AIR BAG OFF ligh t in the cen ter
of the ins trument panel will come on and stay
o n.
T he front airbag on the passenge r sid e may
not dep loy (the PASSENGER AIR BAG OFF
li ght does not illuminate a nd stay lit) i f:
-a small adu lt or teenager is on the front pas
senger seat
- a passenger who is not sitting upright w ith
their back against a non-reclined backrest
with their feet on the vehicle floor in front
of the seat is on the front passenger seat.
I f the front passenger airbag deploys, the
Federal Standard requires the airbag to meet
the " low risk" deployment criteria to help re
duce 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 electron ic control
un it

Always rem emb er: Please be sure to read the
important information in the sections that
follow and be sure to heed all of the WARN
INGS.
A WARNING
T o reduce the risk of injury when an ai rbag
inflates, a lways wear safety belts prope rly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of inj ury is much higher.
- You w ill also receive serious inju ries and
cou ld even be killed if you are up against
the a irb ag or too close to it whe n it in
flates - even with an Advanced Airbag
¢page 111 .
.&_ WARNING
-
A child in a rearward-facing child safety
seat installed on the front passenger seat
w ill be seriously injured and can be k illed if
the front a irbag inf lates - even with an Ad
vanced Airbag System.
- Although the Advanced Airbag System in
your vehicle is designed to turn off the
front a irbag when a rearward-fac ing
child restraint has been installed on the
front passenger seat, nobody can abso l u te ly guarantee that deployment is im
poss ible in al l conceivable situations th at
may happen d uring the useful life of your
vehicle.

.&_ WARNING
I f, in except iona l circumstances, you must
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 put the forward-facing child re
straint up against or very near the instru
ment panel.
- Always move the passenger seat into its
rea rmost pos ition in the seat's fore and
aft ad justment range, as far away from
the airbag as possible, before installing
the forward-fac ing ch ild restra int. The
backrest must be ad justed to an upright
position.
- Ma ke sure that the

Advanced Airbag System components
T he front passenge r seat in yo ur vehicle has a
lot of very important parts of the Advanced
Airbag System in it . These parts include the
weight-sensing mat, sensors, wiring, brack ets, and more. The funct ion of the system in
the front passenger seat is checked by the
electronic control unit when the ignition is on .
The cont rol unit monito rs the Advanced A ir
bag System and turns the airbag indicator
l igh t on when a malfunct ion in the system

118 Airbag system
components is detected. The function of the
airbag indicator light is described in greater
detail below. Because the front passenger
seat contains important parts of the Ad
vanced Airbag System, you must take care to prevent it from being damaged . Damage to
the seat may prevent the Advanced Airbag 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 vehicle that
measure vehicle acceleration/deceleration
to provide information to the Advanced Air bag System about the severity of the crash.
- An electronic control unit, with integrated
crash sensors for front and side impacts .
The control unit "decides " whether to fire
the front airbags based on the information received from the crash sensors. The control
unit also "decides" whether the safety belt
pre tensioners should be activated.
- An Advanced Ai rbag with gas generator for
the driver inside the steering wheel hub.
- An Advanced Airbag with gas generator in
side the inst rument panel for the front pas
senger.
- A weight-sensing mat under the upholstery
padding of the front passenger seat cushion
that measures the total weight on the seat.
The information registered is sent continu
ously to the electronic control unit to regu
late deployment of the front Advanced Air
bag on the passenger side.
- An airbag monitoring system and indicator
light in the instrument cluster
¢page 121.
- The PASSENGER AIR BAG OFF light comes
on and stays on in the center of the instru
ment panel ¢
page 122, fig. 120 and tells
you when the front Advanced Airbag on the passenger side has been turned off.
- A sensor below the safety belt latch for the
front seat passenger to measure the tension
on the safety belt. The tension on the safety
belt and the weight registered by the
weight-sensing mat help the control unit "decide" whether the front airbag for the front passenger seat should be turned off or
not
¢ page 112, Child restraints on the
front seat -some important things to
know.
- A sensor in the safety belt latch for the driv
er and for the front seat passenger that
senses whether that safety belt is latched or not and transmits this informa tion to the
electronic control unit .
.&_ WARNING
Damage to the front passenger seat can
prevent the front airbag from working
properly.
- Improper repair or disassembly of the
front passenger and driver seat will pre
vent the Advanced Airbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
driver seat from the vehicle.
-Never remove the upholstery from the
front passenger seat.
- Never disassemble or remove parts from
the seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or place them on the seat. If the weight
sensing mat in the passenger seat is
punctured it cannot work properly.
- Never carry things on your lap or carry
objects on the passenger seat. Such
items can increase the weight registered
by the weight-sensing mat and send the
wrong information to the airbag control
unit.
- Never store items under the front pas
senger seat. Parts of the Advanced Air
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper ly.
- Never place seat covers or replacement
upholstery that have not been specifical ly approved by Audi on the front seats .
- Seat covers can prevent the Advanced
-
Airbag System from recognizing child .,..
restraints or occupants on the front pas
senger seat and prevent the side airbag
in the seat backrest from deploying prop
erly.
- Never use cushions, pillows, blankets or
similar items on the front passenger
seat. The add itional padd ing will prevent
the weight-sens ing mat in the seat from
accurately reg istering the ch ild restra int
or person on the seat and preve nt the
Advanced Airbag System from func tion
ing properly .
- If you must use a child restra int on the
front passenger seat and the ch ild re
straint manufacturer's instructions re
quire the use of a towel, foam cush ion or
something else to properly position the
child restraint, make certa in that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re
st ra int is installed on the front passen
ger seat .
- If the
PA SSE NGER AIR BAG OFF light
does not come on and stay on, have the
airbag system inspected by your Audi dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the side airbags s upplement the protection of
fered by the front three-point safety be lts
with pretensioners and load limiters and the
adjustab le head restra ints to he lp 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 act ivat ion of the safety be lt preten
sioners depend on the dece le rat ion measured
by the c rash sensors and registered by the
e lectronic control un it . Crash severity depends
on speed and dece leration as well as the mass
and stiffness of the vehicle or object involved in the crash .
Airbag system 119
When the electronic control unit registers a
low severity cras h and the safety belt is being
used, the airbag will not dep loy. If the safety
belt is not being used, the first stage deploys,
followed by the second stage after a much lat er t ime in the crash sequence.
If the electron ic control unit registers a crash
of medium severity, the first stage of the air bag deploys followed by the second stage at a
much later time in the crash sequence -re
gardless of whether the safety belt is be ing
used or not . In higher sever ity crashes as reg
iste red by the elect roni c cont rol unit, bot h the
first and se cond s tages deploy almost at the
same t ime.
On the passenger side, regardless of safety
belt use, the airbag w ill be tu rned off if the
weight on the passenger sea t is less than the
amount programmed in the electronic control
u nit . The front airbag on the passenger side
will a lso be turned off if one of the child safe
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recognized on the seat. The
PASS ENGER A IR
BAG OFF light comes on and stays on to tell
you when the front Adva nced A irbag on the
passenger side has been turned off
¢ page 112, Child restraints on the front seat
- some important things to know .
_&. WARNING ~
To reduce the risk of inj ury when an a irbag
inflates, always wear safety be lts properly.
- If you are unrestrained, leaning forward,
sitting sideways or o ut o f position in any
way, your risk of injury is m uch higher.
- You will a lso receive serious injuries and
could even be killed if yo u are up against
the airbag or too close to it when it in

More important things to know about
front airbags
F ig. 1 19 Inflated fro nt airbags
Safety belts are impo rtant to help keep fro nt
seat occupants in the p roper seated pos it io n
so that airbags can unfo ld prope rly and pro
vide supplemental protection in a fronta l co l
lision .
The front a irbags are designed to provide ad
d itiona l protect ion for the chest a nd face of
the dr iver and the front seat passenger when:
- safety belts are worn properly,
- the seats have been positioned so that the
occupant is properly seated as far as possi
ble from the a irbag,
- and the head restraints have been properly
adjusted .
Because airbags inflate in the blink of an eye
with great force, things you have on your lap or have placed on the seat could become dan
gerous projectiles, and be pushed into you if
the airbag inflates .
When an a irbag deploys, fine dust is released.
This is normal and is not caused by a fire in
the vehicle . This dust is made up mostly of a
powder used to lubricate the airbags as they
deploy. It cou ld irritate ski n.
It is important to remember that while the
supp lemental airbag system is designed to re
duce the l ikelihood of serious inj uries, other
i n juries, fo r example swelling, bruisi ng and
m inor abrasions, ca n also happe n when air
bags in flate. Airbags do not protect the a rms
or the lower pa rts of the body. Front airbags
only supplement the t hree point safety belts
in some frontal collisions in which the vehicle deceleration
is high eno ugh to deploy the air
bags .
Front airbags will not deploy:
- if the ignition is sw itched off when a c rash
occu rs,
- in side co llisions,
- in rear-end co llisions,
- in rollovers,
-when the crash deceleration measured by the airbag system is less than the min imum
threshold needed for a irbag deployment as
reg istered by the electronic control unit .
The front pass enge r airbag will al so not
deploy:
- when the front passenger seat is not occu
p ied,
- when the weight on the front passenger
seat as sensed by the Advanced Airbag Sys
tem indicates that the front ai rbag on the
passenger side has to be turned off by the
elec troni c control un it (the
PASSENGER AIR
BAG OFF
li ght comes on and stays o n).
_&. WARNING ~
Si tting in the wrong position can increase
the r isk o f se rious injury i n crashes.
- To reduce the risk of inju ry w he n t he air
bags inflate, the drive r and passengers
m ust always sit in an upr ight position,
m ust not lean aga inst or place any part
of their b ody too close to the area where
the airbags a re located .
- Occupants who are unbelted, out of posi
tion or too close to the a irbag can be se
rio usly injured by a n airbag as it unfolds
wit h great force in the blink of an eye
<=:>page 112 .
_&. WARNING ~ -
A child in a rearward-fac ing c hild safety
seat installed on the front passenger seat
will be serio usly injured a nd ca n be killed if
the front air bag in fla tes -even with an Ad
vanced A irbag Sys tem.
-The inflating airba g will hit the child
safety seat or infant carrier wit h great
f o rce and w ill smash t he ch ild safety seat
and child aga inst the backrest, cente r
arm rest, d oor or roof.
- Never install a r earward facing child
sa fety seat on the front pass eng er s eat
unless the
PASSENGER AIR BAG OFF
light c omes on and stays on. If the PAS
S ENGER AIR BAG OFF
ligh t does no t
c o m e on and stay on, the inflating airbag
will hit the child safety seat or infant car
rier with great force and will smash the
child safety seat and child against the
backrest, door or roof. Have the airbag
system inspected immediately by your
authorized Audi dealer .
A WARNING
Objects between you and the a irbag will
increase the risk of injury in a crash by in
terfering with the way the airbag unfolds
or by being pushed into you as the a irbag
inflates.
- Never hold th ings in your hands or on
your lap when the vehicle is in use .
- Never transport items on or in the area
of the front passenge r seat. Objects
cou ld move into the area of the front air
bags dur ing braking or other s udden ma
neuver and become dangerous projec
ti les that can cause serious personal in
jury if the airbags inflate.
- Never place o r attach accessories or oth
er objects (such as cup ho lders, tele
phone brackets, large, heavy or b ulky 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 could cause injury in a crash, es
pecially when the airbags inflate.
- Never recline the front passenger's seat
to transport objects. Items can also
move in to the area of the side airbag or
the front airbag dur ing braking or in a
sudden maneuver . Objects near the air -
-
Airbag system 12 1
bags can become projectiles and cause
inju ry, partic ularly when the seat is re
clined.
A WARNING
The fine dust created when airbags deploy
can cause breathing prob lems for people
with a history of asthma or other breath
ing cond itions.
- To reduce the risk of breath ing problems,
those with asthma o r other respiratory
conditions shou ld get fresh air r ight
away by getting o ut of the veh icle or
open ing windows or doors.
- If you are in a collision in which airbags
deploy, was h your hands and fa ce with
mild soap and wate r before ea ting.
- Be ca reful not to get the dust into your
eyes, o r into any cuts or sc ratches .
- If the resid ue should get into your eyes,
