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 163),
-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

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

- 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 147 .
-A sensor in each front seat registers the dis
tance between the respective seat a nd the

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
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 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 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 .
-If you must use a child restra int on the
front passenger seat and the chi ld re-
A irbag system 145
straint manufacturer's instructions re
quire the use of a towel, foam cushion or
something e lse to properly position the
child restraint, make certain that the
PASSENGER AIR BAG OF F light comes
on and stays on whenever the ch ild re
straint is installed on the front passen
ger seat.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immed i
ately insta ll child rest raint 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
s ide airbags supplement 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 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 a lso be turned off if one of the child safe
ty seats that has been ce rtified under Fede ral
Motor Vehicle Safety S tanda rd 208 has been
recognized on the seat. The
PAS SEN GER 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

146 Airbag system
A WARNING
To reduce the risk of injury when an airbag
inflates, always wear safety belts properly.
- If you are unrestrained, leaning forward,
sitting sideways or out of position in any
way, your risk of injury is much higher .
- You will also receive serious injuries and
could even be killed if you are up against
the airbag or too close to it when it in
flates -even with an Advanced Airbag
~ page 137.
More important things to know about
front airbags
Fig. 134 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can unfold properly and pro
vide supplemental protection in a frontal col lision.
The 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,
- the seats have been positioned so that the
occupant is properly seated as far as possi
ble from the airbag,
- 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 airbag 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 could irritate skin.
It is important to remember that while the
supplemental airbag system is designed to re
duce the likelihood of serious injuries, other
injuries, for example swelling, bruising and
minor abrasions, can also happen when air
bags inflate. Airbags do not protect the arms
or the lower parts of the body . Front airbags
only supplement the three point safety belts
in some frontal collisions in which the vehicle
deceleration is high enough to deploy the air
bags.
Front airbags will not deploy:
- if the ignition is switched off when a crash
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
registered by the electronic control unit .
The front passenger airbag will also not
deploy:
- 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 AIR
BAG OFF
light comes on and stays on) .
A WARNING
-
Sitting in the wrong position can increase
the risk of serious injury in crashes.
- To reduce the risk of injury when the air
bags inflate, the driver and passengers
must always sit in an upr ight position,
must not lean against or place any part
of their body too close to the area where
the airbags are located.

A WARNING
Objects betwee n you and t he a irbag will
increase the risk of in jury in a crash by in
t erfering wi th the way the air bag un folds
or by being pushed into you as the a irbag
inflates.
- Never hold th ings in your hands or on
yo ur lap when the vehicle is in use.
- Never transport i tems 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
t il es that can cause serious personal in
jury if the airbags inflate .
- Never place or attach accessories or oth

-
Airbag system 147
jects) on the doors, ove r o r near the area
marked "AIRBAG" on the steering wheel,
instrument panel, seat backrests or be
tween those areas and yourself . These
objects could cause in ju ry in a c rash , es
pecia lly when the airbags infla te .
- Never recline the front passenger 's sea t
to transport objects. Items can a lso
move into the area of the s ide a irbag or
the front a irbag du ring bra king or in a
sudden maneuve r. O bje cts ne ar the air
bags can become projec tiles and cause
in jur y, partic ula rly when the seat is re
clined .
A WARNING
The fine dust create d when air bags 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 or other respiratory conditions shou ld get fresh air r ight
away by getting o ut o f the veh icle or
open ing windows or doors.
- If you are in a collision in which airbags
deploy, was h your hands and face with
mild soap and wate r before ea ting.
- Be ca reful not to get the dust into your
eyes, o r into any c uts or sc ratches .
- If the resid ue should get into your eyes,

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 ind icator light
¢ page 20
comes when the veh icle is being used,
have the system inspected immediately
by your authorized Audi dealer.
It i s

possible 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
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.
