but less than the weight of a small adult, the
front airbag on the passenger side may deploy (the
PASSENG ER AIR BAG OF F light does not
come on).
For example, the a irb ag 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 132),
-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 seat 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 inju ry through interaction
with the airbag . "Low risk" deployment occurs
in those crashes that take place at lower de
celerations as defined in the electronic control unit
¢ page 120.
Please be sure to read the important informa
tion in the sections that follow and be sure to
heed a ll of the WARNINGS.
_& WARNING
To reduce the risk of injury when an airbag
inflates, a lways 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 w ill also receive serio us injuries and
cou ld 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 passenger seat, nobody can abso lutely guarantee that dep loyment is im
possible in all conceivable situations that
may happen during the usefu l life of your
vehicle.
- 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, door, or roof.
- Never install a rearward facing child
safety seat on the front passenger seat
unless the
PA SSENGER AIR BAG OFF
light comes on and stays on . If the PAS
SENGER AIR BAG OFF
light does not
come on and stay on the inflating a irbag
will hit the child safety seat or infant car rier with great force and wi ll smash the
child safety seat and child against the
backrest, door or roof. Have the a irbag
system inspected immediately by your
author ized Audi dealer.
_& WARNING
If, 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 fo r 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.

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 un it when the ignit ion is on.
The control unit mon itors 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

- Repairs to the front passenge r seat m ust
be pe rformed by qualifie d and p roperly
trained workshop personnel.
- Never remove the front passenger o r
d river seat from t he 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
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re
straint is installed on the front passen
ger seat .
Airbag system 117
-If the PASSENGER AIR BAG OFF light
does not come on and stay on, the inflat
ing 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, door or roof. Have
the airbag system inspected immediately 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. Crash severity depends
on speed and deceleration as well as the mass
and stiffness of the vehicle or object involved
in the crash.
When the electronic 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 time in the crash sequence.
If the electronic 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 being
used or not . In higher severity crashes as reg
istered by the electronic control unit, both the
first and second stages deploy almost at the
same time .
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
IJII,-

amount programmed in the e lectronic 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 Federa l
Motor Vehicle Safety Standard 208 has been
recogn ized 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

8_ WARNING
To reduce the risk of injury when an airbag
inf lates, 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 serio us injuries and
cou ld even be killed if you are up against
the airbag or too close to it when it in

More important things to know about
front airbags
Fig . 122 Inflated front a irbags
Safety belts are important to help keep front
seat occupants in the proper seated position
so that airbags can deploy properly and pro
vide supplemental protection in a frontal col
lision .
The front airbags are designed to provide ad d itional protect ion for the chest and 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 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 inf lates.
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 irr itate skin.
It is important to remember that whi le the
supplementa l airbag system is designed to re
duce the like lihood of serious injuries, other
injur ies, 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
supplement the three point safety belts only
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 sw itched off when a crash
o ccurs ,
- in side co llisions,
- in rear-end collisions,
- in rollovers,
- when the crash deceleration measured by
the airbag system is less than the min imum
threshold needed for a irbag deployment as
registered by the electronic control unit.
The front passenger airbag also will 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 ind icates that the front a irbag on the
passenger side has to be turned off by the ..,.
electronic control unit (the PA SS ENGE R 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 upright posit ion,
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 blin k of an eye
¢page 111.
A WARNING
A child in a rearward-facing child sa fety
sea t insta lled on the front passenger seat
wi ll be seriously injured and can be k illed if
the front ai rbag inflates -even with an Ad
vanced Airbag System.
-
-The inflating airbag will hit the child
safety seat or infant carrier w ith great
force and w ill smash the ch ild safety seat
and child against the backrest, center
armrest , door or roof.
- Never install a rearward facing child
safety seat on the front passenger seat
unless the
PASSENGER A IR BAG OFF
light comes on and stays on . If the PAS
SENGER AIR BAG OFF
light does not
c ome o n and stay on, the inflating airbag
will hit the child safety seat o r infant car
rier wi th 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 in jury in a c rash by in
terfering with the way the airbag unfolds
A irbag system 119
or by be ing p ushed into you as the airbag
inflates.
- Never hold things in you r hands o r on
your lap when the veh icle is in use.
- Never transport items on or in the area
of the front passenger seat . Objects
could move into the a rea of the front air
bags during braking or other sudden ma
neuvers and become dangerous projec
tiles that can cause ser ious personal in
jury if t he a irbags inflate .
- Never p lace or attach accessories or oth
er objects (such as cup holders, te le
phone b rac kets, large, heavy or bulky ob
jects) on the doors, ove r o r near the area
marked "AIRBAG " on the s teering wheel,
instrument panel, seat bac krests or be
tween those areas and yo urself. These
objects could cause inju ry in a c rash, es
pecially when the airbags inflate.
- Never recline the front passenger's seat
to transport objects . Items can a lso
move into the area of the s ide a irbag or
the front a irbag during braking or in a
sudden maneuver. Objects near the air bags can become projec tiles a nd cause
in ju ry, partic ula rly when the seat is re
clined.
A WARNING
T he fine dus t created when airbags deploy
can cause breathing prob lems fo r people
wi th a history of as thma or other breath
ing cond itions.
- T o reduce t he risk of bre ath ing problems,
those wi th asthma o r other respiratory
conditions s hou 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, wash your hands and face with
mild soap and water before eating .
- Be ca reful not to get the dust into your
eyes, or into any c uts or scratches.
- If the resi due should get into your eyes,
f lush them w ith wate r.

Important safety instructions on
monitoring the Advanced Airbag System
A WARNING
An airbag system that is not functioning
properly cannot provide supplemental pro
tect ion in a frontal crash.
- If the airbag indicator light comes on, it
means that there 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 i nspected imme
diately by your author ized Audi dealer.
A WARNING
If the front air bag inflates, a ch ild witho ut
a child restra int, or in a rearwa rd-fac ing
child safety seat, or in a forward- facing
child restraint that has not been prope rly
installed will be serious ly injured and can
be killed.
- Even though your ve hicle is equipped
with an Advanced Airbag System, make certain that all children, especially 12
years and younger, a lways ride proper ly
restrained for their age and s ize.
- Never install a rearward facing child
safety seat on the front passenge r seat
unless the
PASSENGER AIR BAG OFF
light comes on and stays on. If the PAS ·
S ENGER AIR BAG OFF
light does not
come on and stay, on the inflating airbag
wi ll hit the child safety seat or infant car
rier with great fo rce 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 tight tether or other strap on a rear ward-facing child restra int attached to
the front passenger seat can put too much pressure on t he weight-sens ing
mat in the seat and register mo re weight
than is actually on the seat. The heavier
we ight registe red can make the system
-
wo rk as though an adult we re on the seat
and deploy the Advanced Airbag when it
must be suppressed, causing serious or
even fata l injury to the ch ild.
- If, i n exceptiona l circumstances, you
must install a forward-fac ing c hild re·
straint on the front passenger seat, al
ways move the seat i nto its rearmost po
sition in the seat's fore and aft adjust
ment range, as fa r away from the a irbag
a s poss ible. The b ackrest mus t be ad just
ed to an upright pos ition . Make s ure that
the
PASSENGER AIR BAG OFF light
comes on and stays on all the time when
ever the ignit ion is switched on.
A WARNING
=
- If the PASSENGER AIR BAG OFF light
does not go out when an adult is sitt ing
on the front passenger seat after taking
the steps described above, have the ai r
bag system inspected by yo ur autho rized
Aud i deale r before t ransporti ng anyone
on the front passenger se at.
