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 be lts
with pretensioners and load limiters and the
adjustable head restra ints* to help reduce the
risk of injury in a wide range of acc ident and
crash situat ions. Be sure to read the impor­
tant information abo ut safety and heed the
WARNINGS in this c hapter .
Dep loyment of the Advanced Airbag System
and the activat ion of the safety be lt preten­
sioners depend on the dece lerat ion meas ured
by the c rash senso rs and regis tered by the
e lectronic control u nit. Crash sever ity depends
on speed and deceleration as well as the mass
and stiffness of the vehicle or object involved
i n the c rash.
On the passenger side, regard less of safety
be lt use, the front passenger front al airbag
will be turned off i f the e lectrical capacitance
measured by the capac itive passenger detec­
tion system on the front passenger seat is less
than the amount programmed in the electron­ ic control unit. The front passenger frontal air­
bag will a lso be turned off if the capacitance
measured by the system for the front passen­
ge r seat equa ls that of an infant of abo ut on e

A WARNING
To reduce the risk of injury when a n airbag
inflates, a lways 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 w ill also receive serious injuries and
cou ld even be killed if you are up against
the a irbag or too close to it when it in- flates

Safety be lts are important to he lp keep front
seat occupants in the proper seated position
so that a irbags can unfold proper ly and pro­
vide supplemental protect ion in a frontal col­
lis ion .
The front airbags are des igned to provide ad­
ditional protection for the chest and face of
the driver and the front seat passenger when:
- safety belts are worn proper ly,
- the seats have been posi tioned so that the
occupant is properly seated as far as poss i­
b le from the airbag ,
- and for ad justab le head restraints: the head
restraints have been properly ad justed .

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 ve hicle . 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 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 examp le swelling, bruising and
minor abrasions, can also happen when air-
bags inflate . A irbags do not protect the arms

or the lower parts of the body. Front airbags
supp lement the three-point safety belts only
in some frontal collisions in which the vehicle
dece leration is high enough to deploy the air­
bags.
F ront airbag s will no t deplo y:
- 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 a irbag system is less than the m inimum
threshold needed for airbag deployment as
registered by the electronic control unit.
The f ront pas seng er airbag al so will n ot
deploy:
- when the front passenger seat is not occu­
pied,
- when the electrical capac itance measured by
the capacitive passenger detect io n system
for the front passenger seat indicates that
the passenger side frontal airbag must be switched off by the electronic control unit
(the

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 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 a re unbelted, out of posi­
t ion or too close to the airbag can be se­
riously injured by an airbag as it unfolds

vanced A irbag System.
- The inflating airbag will hit the ch ild seat
or infant carrier with great force and will
smash the child seat and child against
the backrest, center armrest, door or
roof.
- Always install rear-fac ing ch ild seats on
the rear seat.
- If you must install a rearward fac ing
child seat on the front passenger seat because of exceptional circumstances
and the

A WARNING
r---------
O b j e cts 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 be ing pushed into you as the airbag
inflates.
- Never hold things in your hands or 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 area 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 the a irbags inflate.
- Never p lace or attach accesso ries o r oth­
er objects (such as cup holders, te le­
phone b rac kets, large, heavy or bulky ob ­
jects) on the doors, over 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 injury in a crash, es­ pecially when the airbags inflate.
- Never recline the front passenger's seat
to transport objects. Items can also

cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout ob jects on the seat .
- Always make sure that there is nothing
on the front passenge r seat that will

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 Audi,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag sensors and sent to the electron ic control
unit. Some suspension changes can, for exam­
ple, increase the force levels measured by the
sensors and make the airbag system deploy in
crashes in which it would not deploy if the
changes had not been made. Other kinds of
changes may reduce the force levels meas­
ured by the sensors and prevent the airbag
from deploying when it should .
A 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 insta lled on your vehicle.
- Never use tire-rim combinations that
have not been approved by Audi.
Airbag system 163
Knee airbags
Description of knee airbags
Applies to vehicles: wi th knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
Fig. 144 Driver 's kn ee airbag
The dr iver knee airbag is in the instrument
panel underneath the steering wheel
¢
fig. 144, the airbag for the passenger is at
about the same height in the instrument pan­
el underneath the glove compartment.
The knee airbag offers additional protection
to the driver's and passenger's knees and up ­
per and lower thigh areas and supplements
the protection provided by the safety belts.
If the front airbags deploy, the knee airbags
also dep loy in frontal collisions when the de­
ployment threshold stored in the control unit
is met¢
page 156, More important things to
know about front airbags.
In addition to their normal safety function,
safety belts help keep the driver or front pas­
senger in position in a frontal collision so that
the airbags can provide supplemental protec­
tion.
The airbag system is not a substitute for your
safety belt. Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the airbag system can
only help to protect you if you are wearing
your safety be lt and wearing it properly. This
is why you should always wear your safety
belt, not just because the law requires you to
do so
