Fo r exa mple, the airbag may depl oy 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 safety seats listed
¢ page 160),
-a ch ild who has outgrown child rest raints is
on the front passenger seat.
I f the front passenger airbag is turned off , the
PA SSENGER AIR B AG OFF light in the center
of the inst rument panel w il l come on and stay
on.
The front a irbag on the passenger side may
not deploy (the PASSENGER AIR BAG OFF
light does not illuminate and stay lit) if:
- a small adult or teenager is on the front pas
senger seat
- a passenger who is not sitt ing upr ight w ith
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the sea t is on the front passenge r seat.
If 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 inj ury through in teraction
with the airbag . "Low risk" deployment occurs
in those crashes that take place at lower de
celerations as defined in the electronic control unit.

Alway s remember : Even though you r vehicle
is equipped with Advanced Airbags, the safest
p lace 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 all of the WARNINGS.
_&. WARNING
To reduce the risk of injury when an airbag
inflates, always wear safety belts properly .
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of injury is much highe r.
- You w ill also receive serious injuries and
could even be killed if you are up against
the a irbag or too close to it when it in-

_&. WARNING
A child in a rearward-fac ing ch ild safety
seat installed on the front passenger seat
will be ser ious ly injured and can be killed if
the front airbag inflates - even with an Ad
vanced A irbag System .
-Although 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 passenge r seat, nobody can abso
lutely guaran tee that dep loymen t is im
possible in all conceivable situations that
may happen during the usefu l life of your
veh icle.
- The inflating airbag will hit the child
safety seat or infant carrier with great
force and will smash the child safety seat
and child against the backrest, center
armrest, door, or roof .
-Always install rearward -facing chi ld re
straints in the back seat.
- If you must install a rearward fac ing
child safety seat on the front passenger
seat because of exceptional c ircumstan
ces and the

Advanced Airbag System components
The fron t passenger sea t in your vehicle h as a
lot of very important par ts of the Advanced
Airbag System in it. These parts include t he
weight -sensing mat, sensors, wiring, brack
ets, and more. The function 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 System and turns the airbag indicator
l ight on when a ma lfunction in t he system
components is detected. The func tion of the
a ir bag ind icator light is described in greater
detai l be low . Because the front passenger
seat contains important parts of the Ad
vanced A irbag System, you m ust take care to
prevent it from be ing 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 Airb ag Sy stem
consists of the following:
- Crash sensors in the front of the veh icle that
measure veh icle acceleration/deceleration
to provide information to the Advanced Air
bag System abou t the seve rity of the crash.
- An electron ic co ntrol unit, with integ rated
crash sensors for front and side impacts .
T he cont ro l unit "dec ides " w het her to fire
the front airbags based on the information
received from the crash senso rs . The contro l
unit a lso "decides" whethe r the safety be lt
pretensioners should be activated . -
An Advanced A irbag w ith gas generator and
cont ro l valve for the d river inside the steer
ing wheel h ub.
- An Advanced A irbag with gas ge nerator and
contro l valve inside the instrument pane l for
the front passenger.
- A weight-sensing mat under the up ho lstery
pad ding of the front passenger seat cushion
that measures the total weight on the seat.
The informat ion registered is sent continu
ously to the electronic contro l unit to regu
late deployment of the front Advanced Air bag on the passenger side .
- An airbag monitor ing system and i ndicator
light in the i nstr ument cluster ~
page 148 .
-A sensor in each front seat registers the dis
tance between the respective seat a nd the
steer ing whee l o r i ns trument panel. The i n
formation registered is sent cont inuo usly to
t he ele ctr onic cont ro l uni t to regula te de

A WARNING
Damage to the front passenger seat can
p revent the front airbag from work ing
properly.
-
Page 147 of 286

-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 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-
Airbag system 145
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
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 Adv a 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. The amount of infla
tion of the front airbags can also be adapted
to the front sea t position, depending on the
distance between the respective front seat
and the steering wheel or instrument panel as registered 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 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
unit. 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

More important things to know about
front airbags
F ig. 15 4 Inflated front airbags
-,.._
::: :i:.
"' a)
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 supp lemental protection in a frontal co l
lision.
The front a irbags are designed to provide ad
d itiona l protect ion for the chest and face of
the driver and the front seat passenger when :
- safety belts are worn properly,
- the seats have been posit ioned so that the
occupant is proper ly 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 p
laced on the seat cou ld become dan
gerous projecti les, and be p ushed into you if
the a irbag inf lates.
When an airbag deploys, fine dust is re leased.
T his is norma l and is not caused by a fi re in
the vehicle . This dust is made up mostly of a
powder used to lubricate the airbags as they
deploy. It could irritate skin .
It is important to remembe r that while the
supplementa l airbag system is designed to re
duce the like lihood of serious injur ies, other
injur ies, for example swelling, bruising and
minor abrasions, can also happen when air
bags inflate . A irbags do not protect the arms
o r the lower parts of the body. Front a irbags
only supp lement the three point safety belts
in some fronta l co llisions in wh ich the vehicle
deceleration is high enough to deploy the air
bags .
Front a irbags will not deploy:
- if the ignition is switched off when a c rash
occurs,
- in side collisions,
- in rear-end collisions,
- in rollovers,
- when the crash deceleration measured by
the airbag system is less than the minimum
threshold needed for airbag deployment as
reg istered by the electronic control unit.
The front pa ssenger airbag will al so not
deplo y:
- when the front passenger seat is not occu
pied,
- when the weight on the front passenger
seat as sensed by the Advanced Airbag Sys
tem indicates that the front airbag on the
passenger side has to be turned off by the
electronic control un it (the
PASSENGER A IR
BAG OFF
l ight comes on and stays on).
A WARNING
Sitting in the wrong pos ition can increase
the r is k of serious injury in crashes.
- To reduce the risk of injury when the air
bags i nflate, the driver and passengers
Page 149 of 286

must always sit in an upright position,
must not lean against or place any part
of the ir body too close to the area where
the a irbags are located .
- Occupants who are unbelted, out of posi
t ion or too close to the airbag can be se
riously injured by an airbag as it unfolds
with great force in the blink of an eye
~ page 138.
A WARNING
A child in a rearward-facing child safety
seat insta lled on the front passenger seat
wi ll be seriously injured and can be k illed if
the front airbag inflates -even with an Ad
vanced Airbag System.
- T he inflating airbag will hit the child
safety seat or infant carrier with great
force and wi ll smash the ch ild safety seat
and child against the backrest, center
armrest, door or roof.
- Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im
med iately install the rear-facing child
safety seat in a rear seating position and
have the a irbag system inspected by your
authorized Audi dealer .
A WARNING
Objects between you and the airbag 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 airbag
inf lates.
- Never hold things in your hands or on
your lap when the vehicle is in use.
- Never transport items on or in the area
of the front passenger seat. Objects
cou ld move into the area of the front air
bags during braking or other sudden ma
neuver and become dangerous projec-
A irbag system 147
tiles that can cause serious personal in
jury if the a irbags inflate.
- Never place or attach accessories or oth
er objects (such as cupholders, 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 areas and yourself. These
objects could cause injury in a crash, es
pecia lly when the airbags inflate.
- Never recline the front passenger's seat
to transport objects. Items can also
move into the area of the side a irbag or
the front airbag during braking or in a
sudden maneuver . Objects near the air
bags can become projectiles and cause
injury, particularly when the seat is re
clined.
A WARNING
The fine dust created when airbags deploy
can cause breathing problems for people
with a history of asthma or other breath ing cond itions.
- To reduce the risk of breath ing problems,
those with asthma or other respiratory
conditions shou ld get fresh air right
away by getting out of the veh icle or
open ing windows or doors.
- If you are in a collision in which airbags
deploy, wash your hands and face with mild soap and water before eating.
- Be careful not to get the dust into your
eyes, o r into any cuts or scratches .
- If the residue should get into your eyes,
f lush them with water. •

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not functioning properly cannot provide supplemental pro
tection in a frontal crash.
- If the airbag indicator light¢
page 20
comes when the vehicle is being used,
have the system inspected immediately
by your authori zed Audi dealer. It is pos
sible that the airbag will inflate when it
is not supposed to, or will not inflate
when it should .
A WARNING
If the front airbag inflates, a child without
a child restraint, in a rearward-facing child
safety seat or in a forward-facing child re
straint that has not been properly installed
will be seriously injured and can be killed.
- Even though your vehicle is equipped
with an Advanced Airbag System, make certain that all children, especially 12
years and younger, always ride on the back seat properly restrained for their
age and size.
- Always install forward or rear-facing
child safety seats on the rear seat -even
with an Advanced Airbag System.
- If you must install a rearward-facing
child safety seat on the front passenger
seat because of exceptional circumstan
ces and the
PASSENGER AIR BAG OFF
light does not appear and stay on, imme
diately install the rear-facing child safety
seat in a rear seating position and have
the airbag system inspected by your au
thorized Audi dealer.
- A tight tether or other strap on a rear
ward-facing child restraint attached to
the front passenger seat can put too
much pressure on the weight-sensing
-
mat in the seat and register 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 serious or
even fatal injury to the child.
- If, in exceptional circumstances, you
must install a forward-facing child re
straint on the front passenger seat, al
ways move the seat into its rearmost po
sition in the seat's fore and aft adjust
ment range, as far away from the airbag
as possible. The backrest must be adjust
ed to an upright position. Make sure that
the
PASSENGER AIR BAG OFF light
comes on and stays on all the time when
ever the ignition is switched on .
A WARNING
-
-
-If the PASSENGER AIR BAG OFF light
does not go out when an adult is sitting
on the front passenger seat after taking
the steps described above, make sure the
adult is properly seated and restrained at
one of the rear seating positions.
- Have the airbag system inspected by
your authorized Audi dealer before trans
porting anyone on the front passenger
seat.
(D Tips
If the weight-sensing mat in the front pas
senger seat detects an empty seat, the
front airbag on the passenger side will be
turned off, and
PASSENGER AIR BAG OFF
will stay on.
Repair , care and disposal of the airbags
Par ts of the airb ag system are ins talled 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. .,..
