192 Airbag system
-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- 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. 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, regard less of safety
be lt use, the airbag will be turned off if the
weight on the passenger seat is less than the
amo unt programmed in the electronic control
un it. The front airbag on the passenger side
w ill 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
recog nized 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 t urned off
Q page 186, Child restraints on the front seat
- some important things to know .
_&. 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, yo ur risk of inj ury 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
flates -even with an Advanced Airbag

More important things to know about
front airbags
F ig. 2 11 Inflated front airbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can unfo ld properly and pro
vide supplemental protection in a fronta l col
l ision.
A irba g sy stem 193
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
- t he seats have bee n positioned so that the
occ upan t is properly seated as far as poss i
b le from the airbag
- and the head restraints have been properly
adj usted
Because airbags inflate in the blink of an eye
with great force, t hings you have on your lap
or have placed on the seat co uld become dan
gerous projecti les, and be p ushed in to you if
the a irbag inf lates.
When an airbag deploys, fine dust is re leased.
T his is no rma l and is not caused by a fi re in
the vehi cle. This dust is made up mos tly of a
powder used to lub ricate the airbags as they
deploy. It could irritate skin.
It is important to remembe r that wh ile the
s u pplementa l airbag system is designed to re
duce the like lihood o f serious injuries, other
injuries, for example swelling, bruising and
minor abrasions, can a lso happen when air
bags inflate . A irbags do not protect the arms
or the lower parts of the body. Front airbags
supplement the th ree-point safety belts only
i n some frontal co llisions in which the vehicle
deceleration is high enough to deploy the air
bags.
Front a irbags will not deploy :
-if the ignition is sw itched off when a crash
occurs
- in side collisions
- in rear-end co llisions
- in rollovers
- when the crash dece leration meas ured by
the air bag system is less than the minimum
threshold needed for airbag deployment as
reg istered by the electronic cont ro l unit
The front passenger airbag also will not
deploy:
- when the front passenger seat is not occu-
pied ..,.
194 Airbag sys te m
- 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
electron ic control unit (the
PA SSEN GER 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 r isk of injury when the air
bags inflate, the driver and passengers
must always sit in an upright position,
must not lean against o r place any pa rt
of the ir body too close to the area where
the airbags are located .
- Occ upants 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 186.
A WARNING -
A child in a rearward-facing child safety
seat installed on the front passenger seat
w ill be seriously injured and can be k illed if
the front a irbag inflates -even with an Ad
vanced Airbag System.
- The inflating a irbag will hit the child
safety seat or infant carrier with great
force and w ill smash the ch ild safety seat
and child against the backrest, center
armres t, door or roof.
- Always install rear-facing child safety
seats on the rear seat.
- If you must install a rearward-fac ing
child safety seat on the front passenger
seat because of excep tional circ umstan
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im
mediately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer.
A WARNING
Objects between you and the airbag will
i nc rease the r isk of injury in a crash by in
terfering with the way the airbag unfolds
or by be ing pushed into you as the airbag
i n flates.
- Never hold things in yo ur hands or on
your lap when the veh icle is in use.
- Never transpo rt items on or in the area
of the front passenger seat. Objects
could move into the a rea of the front air
b ags du ring bra king or other sudden ma
neuvers and become dangero us projec
tiles that can cause serious personal in
jury if the ai rbags inflate.
- Never p lace or attach accessories or oth
er objects (such as cupholde rs, tele
phone brackets, large, heavy or bulky ob
jects) on the doors, ove r or near the area
marked "AIRBAG" on the steer ing whee l,
instrument panel , seat backrests or be
tween those areas and yourself . These
objects could ca use in jury in a c rash, es
pecially when the airbags infla te.
- Never recline the front passenger 's seat
to transpo rt objects . Items can a lso
move into the a rea of the s ide airbag or
the front airb ag d uring bra king or in a
sudden maneuve r. Objects nea r the air
bags can become projectiles and cause
in ju ry, partic ularly when the seat is re
clined.
- Never tilt the front passenger seat back
rest forward when the vehicle is moving .
An inflating a irbag w ill force the back
rest backward and can injure rear seat oc
cupants.
A WARNING
The fine dust created when airbags deploy
can cause breathing prob lems for people
with a history of asthma or other breath i ng cond itions.

away by getting out of the vehicle or
opening 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 you r
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 p ro
tection 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 Ai rbag System .
It is possible that the airbag will inflate
when it is not s upposed 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 without
a child restraint, or in a rearward-fac ing
child safety seat, o r in a forward-facing
child restraint that has not been properly
installed will be serio usly 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
A irbag sys tem 197
back seat properly rest rained for their
age and size.
- Always install forward or rear-facing
child safety seats on the rear seat -even
with an Advanced A irbag System.
- If you must install a rearwa rd-facing
child safety seat on the front passenger
seat because of exceptional c ircumstan
ces and the
PASSENGER AIR BAG OFF
light does not appear and stay on, imme
diate ly install the rear-facing child safety
seat in a rea r seat ing pos ition and have
the air bag sys tem inspected by y our au
thori zed A udi dealer.
- A t ight tether or other strap on a rea r
ward-facing child rest raint attached to
the front passenger seat can p ut too
m uch p ressu re 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 ser ious or
even fata l injury to the ch ild.
- If, in exceptiona l circumstances, you
m ust install a forward-fac ing ch ild re
straint on the front passenger seat, al
ways move the sea t into its rearmos t po
sition in the seat's fore and aft adjust
ment range, as far away from the a irbag

acceleration in a side collision is high
enough to activate the airbag.
How supplemental side airbags work
Side airbags deploy instantly and can help re duce the risk of upper torso injuries for occu
pants who are properly restrained.
Fig. 214 Inflated side airbags on left side of veh icle,
rear side airbag optional equipment
When the system is triggered, the airbag is
filled with propellant gas and breaks through a seam in the seat surface area marked "AIR
BAG". It expands between the side trim panel
and the passenger . In order to help provide
this additional protection, the side airbag must inflate within a fraction of a second at
very high speed and with great force. The sup
plemental side airbag could injure you if your
seating position is not proper or upright or if
items are located in the area where the sup
plemental side airbag expands. This applies
especially to children
¢ page 205, Child Safe
ty.
Supplemental side airbags inflate between
the occupant and the door panel on the side
of the vehicle that is struck in certain side col
lision
~ fig . 214.
Although they are not a soft pillow, they can
"cushion" the impact and in this way they can
help to reduce the risk of injury to the upper
part of the body .
A fine dust may develop when the airbag de ploys. This is normal and does not mean there
is a fire in the vehicle.
Airbag system 201
Important safety instructions on the
side airbag system
Airbags are only supplemental restraints. Al
ways properly wear safety belts and ride in a
proper seating position.
There is a lot that you and your passengers
must know and act accordingly to help the
safety belts and airbags do their job to pro
vide supplemental protection.
A WARNING
An inflating side airbag can cause serious
or fatal injury. Improperly wearing safety
belts and improper seating positions in
crease the risk of serious personal injury
and death whenever a vehicle is being
used.
- In order to reduce the risk of injury when
the supplemental side airbag inflates:
- Always sit in an upright position and
never lean against the area where the
supplemental side airbag is located.
- Never let a child or anyone else rest
their head against the side trim panel
in the area where the supplemental
side airbag inflates.
- Always make sure that safety belts are
worn correctly,
- Do not let anyone sitting in the front
seat put their hand or any other parts
of their body out of the window.
-Always make sure that the side airbag can inflate without interference.
- Never install seat covers or replace
ment upholstery over the front seat
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags deploy.
- Damage to the original seat covers or
to the seam in the area of the side air
bag module must always be repaired
immediately by an authorized Audi
dealer.
