-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

- 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

How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
s ide airbags supp lement the protection of
fered by the front three-poi nt safety belts
with pretensioners and load limiters and the
adjustable head res traints to help reduce the
r isk of inj ury in a wide range of ac ciden t 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 t he activation of the safe ty belt preten
sioners depend on the deceleration measured
by the crash sensors and registered by the
electronic contro l unit. Crash severity depends
on speed and dece leration as we ll as the mass
and stiffness of the veh icle or object involved
in the crash .
When the e lectronic control unit registers a
l ow 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 t ime in the crash sequence.
If the electron ic 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
gard less of whether the safety belt is be ing
u sed or not . In highe r sever ity crashes as reg
iste red by the electronic con trol unit, both the

weight on the passenger seat is less than the
amount programmed in the electronic control
un it. The front a irbag 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
recogn ized on the seat. The

BAG OFF
light comes on and stays on to te ll
you when the front Advanced Airbag on the passenger side has been t urned off
c::> page 185, Child restraints on the front seat
- some important things to know .
~ WARNING
To reduce the risk of injury when an airbag
inf lates, always wear safety belts properly.
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of inj ury is much higher.
- You wi ll also receive serious inju ries and
cou ld even be killed if you are up against
the airbag or too close to it when it in
flates - even with an Advanced Airbag
o page 183.
More important things to know about
front airbags
Fig. 2 09 Inflated front a irbags
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 frontal col lision. T
he 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 prope rly seated as far as poss i
b le from the airbag
- and the head restraints have been properly
ad justed
Because airbags inflate in the bli nk of an eye
with great force, th ings you have on your lap
o r have placed on the seat co uld become dan
gerous p ro jecti les, and be p ushed in to you if
the a irbag inflates.
When an airbag deploys, fine dust is re leased.
T h is is no rma l and is not caused by a fire i n
the ve hicle. This dust is made up mos tly of a
powde r used to lubricate the airbags as they
deploy.
It could irr itate skin.
It i s impo rtant to remember that wh ile the
s u pplementa l airbag system is designed to re
duce the like lihood o f serious injur ies, other
injuries , for examp le swelling, bruising and
minor ab rasions, can also happen when air
bags inflate . A irbags do not protect the arms
or the lower parts of the body. Front a irbags
supplement the three-point safety belts only i n some fronta l col lisions in wh ich the vehicle
deceleration is h igh eno ugh to deploy the air
bags.
Front airbags will not deploy:
- if the ignition is sw itched off when a crash
occurs
- in side co llisions
- in rear-end co llisions
- in rollove rs
- when the crash dece lerat ion meas ured by
the air bag system is less than the min imum
threshold needed for airbag deployment as
reg istered by the elect ronic contro l unit
The front pass enger airbag also w ill not
deploy:
- when the front passenger seat is not occu-
pied .,.
Page 195 of 340

-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 unit (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 upright position,
must not lean against or place any part
of their body too close to the area where
the airbags are located.
- Occupants who are unbelted, out of posi
tion 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
c> page 185.
A WARNING -
A child in a rearward-facing child safety
seat installed on the front passenger seat
will be seriously injured and can be killed if
the front airbag inflates -even with an Ad
vanced Airbag System.
- 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 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
mediately install the rear-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer .
Airbag system 193
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 inflates .
- 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
could move into the area of the front air
bags during braking or other sudden ma
neuvers and become dangerous projec
tiles that can cause serious personal in
jury if the airbags 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
pecially when the airbags inflate.
- Never recline the front passenger's seat
to transport objects. Items can also
move into the area of the side airbag 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.
- Never tilt the front passenger seat back
rest forward when the vehicle is moving.
An inflating airbag will force the back
rest backward and can injure rear seat oc
cupants.
A WARNING
The fine dust created when airbags deploy
can cause breathing problems for people
with a history of asthma or other breath ing conditions.

Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servici ng 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 co llision.
There are some important th ings you have to
know to make sure that the effect iveness of
the system will not be impa ired and that dis
carded components do not cause injury or po l
lute the env ironment.
_& WARNING
Improper ca re, servicing and repair proce
dures can increase the risk of personal in
jury and death by preventing an airbag from deploy ing when needed or deploying
an airbag unexpected ly:
- Never cover, obstr uct, o r change the
steering wheel horn pad or airbag cover
or the instrument pane l or modify them
in any way.
- Never attach any objects such as cu
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
pane l, use only a soft, dry cloth or one
moistened w ith plain water. Solvents or
cleaners co uld damage the airbag cover
o r change the stiffness or strength of the
material so tha t the airbag cannot de

- Never modify the front bumper or parts
of the vehicle body.
-Always make sure that the s ide a irbag
can inflate without interference:
- Never install seat covers or rep lace

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys
tem performs in a crash. For example, using
tire-r im combinations not approved by Aud i,
l owering the vehicle, changing the stiffness o f
the suspension, including the springs, s uspen
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control
un it. Some suspension changes can, for exam
ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in wh ich it would not deploy if the
changes had not been made. Other kinds of
changes may reduce the force levels meas
u red by the sensors and prevent the airbag
from deploying when it should .
The sensors in the safety belt buckle for the
driver and front passenger sea t tell the elec
tronic control module if the safety belt is
latched or not. If the safety belt is being used,
the front airbag will deploy at a slightly high
er rate of vehicle deceleration than if the safe
ty belt is not being used. Therefore, in a par
ticular collision, it is possible that an airbag
will not deploy at a seating position where the safety belt is being used but will inflate at the
position where the safety belt is not being
used.
It is important that nothing interfere
with the safety belt buckles so that the sen- sors can send the correct info
rmation about
safety belt use to the electronic control unit.
.&_ WARNING
-
Changing the vehicle's suspension includ- ing use of unapproved tire-rim combina
tions can change Advanced Airbag per
formance and increase the risk of serious
personal injury in a crash.
- Never install suspension components
that do not have the same performance
characteristics as the components origi
nally installed on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
&_ WARNING
--
Items stored between the safety be lt
buckle and the center console can cause
the sensors in the buckle to send the
wrong information to the e lectronic con
trol module and prevent the Advanced Air
bag System from working properly.
- Always make sure that nothing can inter
fere with the safety belt buckles and that
they are not obstructed.
