Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing mat, sensors, wiring, brack
ets, and more . The fu nction of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on.
The control unit mo nitors the Advanced Air
bag Sys tem and turns the airbag indicator
light on when a ma lfunction in the system
components is detected . The function of the
ai rbag ind icator light is described in greater
detai l below. Because the front passenger
seat contains important parts of the Ad
vanced A irbag System, you must take care to
prevent it from be ing damaged . Damage to
the seat may prevent the Advanced A irbag for
the front passenger seat from doing its job in
a cra sh .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front of the veh icle that
measu re ve hicle ac celera tion/de ce le ra ti on
to provide info rm ation to the Advanced Air
bag System abo ut the severity of the crash . -
An elect ronic contro l unit, with integrated
crash sensors for front and side impacts .
The control un it "decides" whether to fi re
the front a irbags based on the informat ion
received from the crash sensors. The contro l
un it also "decides" whether the safety belt
prete nsioners shou ld be act ivated .
- An Advanced A irbag w ith gas generator for
the dr iver inside the stee ring wheel hub .
- An Advanced A irbag w ith gas generator in
side the instrument panel for the front pas
senge r.
- A we ight-sensing mat under the up ho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat .
The informat io n registe red is sent continu
ou sly to the elec troni c con tro l unit to regu
la te deployment of the front Advanced Air
bag on the passenger side .

A WARNING
Damage to the fr ont passenger seat can
p revent the front airbag from work ing
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
dr iver seat from the veh icle .
- 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-sens ing mat and send the
wrong info rmation to the airbag control
unit.
- Never store items under the front pas
senger seat. Parts of the Advanced Ai r
bag System under the passenger seat
cou ld 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 A udi on the front seats.
- Seat covers can prevent the Advanced
Airbag System from recognizing child re
straints or occupants on the front pas
senger seat and prevent the side airbag in the seat backrest from deploy ing prop
erly.
- Never use cush ions, 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
accu rately reg iste ring the ch ild restra int
or person on the seat and prevent the
Advanced Airbag System from function ing properly .

How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
s ide airbags supp lement the protection of
fered by the front three-point safety belts
with pretensioners and load limiters and the
adjustable head rest raints to help reduce the
risk of inj ury in a wide range of accident and
c rash situations. Be s ure to read the impor
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adv a need A irbag System
and the activation of the safety belt preten
sioners depend on the deceleration measured
by the crash sensors and registered by the
electronic control unit. Crash severity depends
on speed and deceleration as we ll as the mass
and stiffness of the veh icle or object involved
in the crash .
When the e lectronic control unit registers a
low severity crash and the safety belt is being
used, the airbag will not deploy. 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
u sed or not . In higher sever ity crashes as reg
iste red by the electronic control unit, both the

O n the passenger side, regard less of safety
be lt use, the airbag will be turned off if the
weight on the passenger seat is less than the
amount prog rammed in the electronic control
un it. The front a irbag on the passenger side
will also be turned off if one of the child safe
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recogn ized on the seat. The

~ WARNING
To reduce the risk of injury when an airbag
inf lates, a lways wear safety belts properly.
- 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 wi ll also receive serio us inju ries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in

More important things to know about
front airbags
F ig. 198 Inflated front a irbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can u nfo ld properly and pro
vide supplemental protection in a frontal col lision. T
he 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 properly
- t he seats have bee n positioned so that the
occ upan t is prope rly seated as far as poss i
b le from the airbag
- and the head restraints have been properly
ad justed
Because airbags inflate in the bli nk of an eye
with great force, th ings you have on your lap
o r have p laced on the seat co uld become dan
gerous p ro jecti les, and be p ushed in to you if
the a irbag inflates.
When an airbag deploys, fine dust is re leased.
T h is is no rma l and is not caused by a fire i n
the ve hicle. This dust is made up mos tly of a
powde r used to lubricate the ai rbags as they
deploy.
It could irr itate skin.
It i s impo rtant to remember that wh ile the
s u pplementa l airbag system is designed to re
duce the like lihood o f se rious injur ies, other
injuries , for examp le swelling, bruising and
minor ab rasions, can also happen when air
bags inflate . A irbags do not protect the arms
or the lower parts of the body. Front a irbags
supplement the three-point safety belts only i n some fronta l col lisions in wh ich the vehicle
deceleration is h igh eno ugh to deploy the air
bags.
Front airbags will not deploy:
- if the ignition is sw itched off when a crash
occurs
- in side co llisions
- in rear-end co llisions
- in rollove rs
- when the crash dece lerat ion meas ured by
the air bag system is less than the min imum
threshold needed for airbag deployment as
reg istered by the elect ronic contro l unit
The front pass enger airbag also w ill not
deploy:
- when the front passenger seat is not occu-
pied .,.

aw ay by getting out of the vehicle or
opening windows or doors.
- If you are in a collision in which airbags
dep loy, wash your hands and face w ith
mild soap and water before eating.
- Be careful not to get the dust into yo ur
eyes, or into any cuts or scratches.
- If the residue should get into your eyes,
flush them with water.

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not funct ioning
prope rly cannot provide supplemental pro
tect ion in a frontal crash.
- If the airbag indicato r light comes on, it
means that the re may be someth ing
wrong with the Advanced A irbag System.
It is possible that the airbag will inflate
when it is not supposed to, or w ill not in
flate when it should.
- Have the airbag system inspected imme
diately by your author ized Audi dealer .
A WARNING
If the front airbag inflates, a ch ild witho ut
a child restra int, or in a rearward-facing
child safety seat, or in a forward -facing
child restraint that has not been properly
installed will be seriously injured and can
be killed.
- Even though your veh icle is equipped
with an Advanced Airbag System, make
certain that a ll children , especially 12
years and younge r, a lways ride on the back seat properly
restrained for their
age and size.
- Always install forward o r rear-facing
child safety seats on the rear seat -even
with an Advanced A irbag System.
- If you must install a rearward-facing
child safety seat on the front passenger
seat because of exceptiona l circumstan
ces and the
PASS ENG ER AIR BAG OFF
light does not appea r and stay on, imme
diate ly install the rear-facing child safety
seat in a rear seat ing pos ition and have
the airbag system inspe cted by your au
thori zed A udi dealer.
- A tight tether or other s trap on a rea r
ward-facing child restraint att ached to
the front passenger seat can p ut too
m uch p ressure on the weight-sensing
mat in the seat and registe r more weight
than is actually on the seat. The heavier
weight registered can make the system
work as though an adult were on the seat
and deploy the Advanced Airbag when it
must be suppressed causing ser ious or
even fata l injury to t he ch ild.
- If, i n exceptiona l circumstances, you
m ust ins tall a forward-fac ing ch ild re
straint o n the front passenger seat, al
ways move the sea t in to its rearmos t po
sition in the seat's fore and aft adjust
