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 include the
weight-sens ing mat , sensors, w iring, brack
ets, and more. The function of the sys tem in
the front passenger seat is checked by the
e lectronic control unit when the ignition is on .
T he control unit mon itors the Advanced Air
bag System and turns the airbag indicator
light on when a malfunction in the system
components is detected . The function of the
a irbag ind icator light is described in greater
deta il be low . Because the front passenge r
seat conta ins important parts of the Ad
v a nce d Airbag System, you m ust ta ke care to
prevent it from be ing dam aged. 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
consis ts o f the following :
-Crash sensors in the front of the veh icle that
measure veh icle acceleration/dece leration
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 contro l unit "decides" whether to fire
the front airbags based on the information
received from the crash senso rs. The co ntro l
u nit a lso "dec ides " whet he r the safety be lt
pre tensione rs should be a ctivated.
- An Advanced Airbag with gas generator and
control valve for the d river inside the s teer
i ng w hee l hub . -
An Advanced A irbag w ith gas generator and
cont ro l valve inside the instrument pane l for
the front passenger .
- A we ight -sensing mat under t he up ho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat.
The informat io n 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 instr ument cluster
q page 141.
- A sensor in each front seat registers the dis
tance betwee n the respective seat a nd the
s teer ing whee l o r i nstrument panel. The in
formation registered is sent cont inuous ly to

-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 re
straints 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 additional padding will prevent
the weight-sensing mat in the seat from
accurately registering the child restraint
or person on the seat and prevent the
Advanced Airbag System from function
ing properly.
- If you must use a child restraint on the
front passenger seat and the child re
straint manufacturer's instructions re
quire the use of a towel, foam cushion or
something else to properly position the
child restraint, make certain that the
Airbag system 139
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re
straint is installed on the front passen
ger seat.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi
ately install child restraint in a rear seat
ing position and have the airbag system
inspected by your authorized Audi dealer.
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 safety belts
with pretensioners and load limiters and the
adjustable head restraints to help reduce the
risk of injury in a wide range of accident and
crash situations. Be sure to read the impor
tant information about safety and heed the
WARNINGS in this chapter.
Deployment of the Adva need Airbag 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 well as the mass
and stiffness of the vehicle or object involved
in the crash.
On the passenger side, regardless of safety
belt use, the airbag will be turned off if the
weight on the passenger seat is less than the
amount programmed in the electronic control
un it. The front airbag 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
recogni zed on the seat . The
PASSENGER AIR
BAG OFF
light comes on and stays on to tell
you when the front Advanced Airbag on the passenger side has been turned off

A WARNING
If t he front airbag inflates, a ch ild without
a child restra int, in a rearward-facing child
safety seat or in a forward-facing child re
straint that has not been properly insta lled
w ill be seriously injured and can be k illed.
- Even though your veh icle is equipped
with an Advanced Airbag System, make c ertain that a ll children, especially 12
years and younger, a lways ride on the
back seat properly restrained for their
age and size.
- Always instal l forwa rd or rear-facing
child safety seats on the rear seat -even
with an Advanced Airbag System.
- If you must install a rearward -fac ing
child safety seat on the front passenger
seat because of exceptional circ umstan
ces and the
PASS ENG ER AIR BAG OFF
light does not appear and stay on, imme
diately install the rear-fac ing ch ild safety
seat in a rear seating position and have
the a irbag system inspected by you r au
tho riz ed Aud i deale r.
- A tight tether or other strap on a rear
wa rd-facing child restra int attached to
the front passenger seat can put too much pressure on the weight-sens ing
mat in the seat and register mo re weight
than is ac tually on the seat. The heavier
weight registe red can make the system
work as though an adu lt were on the seat
and dep loy the Advanced Airbag when it
must be suppressed caus ing serious or
even fatal injury to the child.
- If, in exceptional circumstances, you
must install a forward-facing child re
st raint on the front passe nger seat, a l
ways move the seat into its rearmost po
sit io n in the seat's fo re and aft adjust
me nt range, as f ar away from the airbag

Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places o n your Aud i. Insta lling,
removing, servicing or repa iring a part in an
area of the veh icle can damage a part of an
airbag system and p revent that system from
working p roperly in a coll is io n.
There are some important t hings you have to
know to make sure that the effectiveness of
the system w ill not be impaired and that dis
ca rded components do not cause inju ry or pol
lute the environmen t.
A WARNING
Imprope r care, serv ic ing and repair p roce
dur es can increase the risk of personal in
ju ry and death by prevent ing an a irbag
from deploying when needed or dep loying
an a irbag unexpectedly:
- Never cover, obstruct , or change the
steer ing whee l horn pad or airbag cover
or the instrument panel or mod ify them
in any way .
"' N

Remember too, airbags will deploy only once
and only in certain kinds of accidents -your
safety belts are a lways there to offer protec
tion in those acc idents in which airbags are
not supposed to deploy or when they have al
ready deployed, for example when your vehi
cle str ikes or is struck by another afte r the
fi rst coll is ion.
This is just one of the reasons why an a irbag is
not a substitute for the safety belt . The airbag
system works most effectively when used with
the safety belts . Therefore, always wear your
safety bel ts correctly .
It is important to remember that while the
supplemental knee a irbag system is des igned
to reduce the like lihood of serious injur ies,
o ther in juries , fo r example, swel ling , bruising,
and minor abras io ns and frict ion bu rns ca n al
so occur when an airbag inflates.
The knee airbag system basically consists
of :
-The elec tronic control mod ule
- T wo inf latab le airbags (airbag and gas gen-
erato r), one for the driver and one for the
front passenger
- T he airbag ind icator light in the instrument
pane l
The knee airbag system will not deploy:
-when the ign ition is turned off
- in frontal collisions w hen the decelerat ion
measured by the control unit is too low
- in s ide collisions
- in rear-end collisions
- in ro llovers
- in the event of a system malfunct io n (wa rn -

r::!> page 19.
& WARNING
- Safety belts and the airbag system can

are in the proper seating posit ion
c::>page 140.
-If the airbag indicator light c::> page 19
comes when the vehicle is be ing used,
have the system inspected immediately
A irba g sy stem 14 7
by your authorized A udi dealer. It is pos
sib le that the airbag will inflate when it
is not supposed to , or will not inflate
when it should .
How knee airbags work
Applies to vehicles: wit h knee airbags
The risk of injury to the leg area can be re
duced by fully deployed knee airbags.
Fi g. 154 In flated a irbags protect ing in a fronta l co lli·
s ion
The knee airbag system has been designed so
that the airbags for the driver and front pas
senger deploy in certain but not all frontal
collisions.
If the front airbags dep loy, the knee airbags
also dep loy in frontal co llisions when the de
ployment threshold stored in the control unit
is met.
When the system deploys, the ai rbags fill
with a propellant gas, and inflate between the l ower part of the instrument pane l and the
driver and t he lower part of the instrument
panel and the front passenger
c::> page 140,
fig . 151 .
Although they are not a soft pi llow, they can
cush io n the impact and in this way they can
help to reduce the risk of injury to the lower
extremit ies .
All of th is takes place in the blin k of an eye, so
fast that many people don't even realize that
the a irbags have deployed. The airbags a lso
i nfla te with a g reat dea l of fo rce and it is im
po rtant for occupant safety that no thing
sho uld be in their way when they deploy.
