150 Airbag system
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 saf ety be lts
with pretensioners and load limiters and the
adjus table head restr aints* 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 about safety and heed the
WARNINGS in this chapter .
Deployment of the Advanced Airbag System
and the activat ion of the safety belt preten­
sioners depend on the decelerat ion measured
by the crash 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
in the crash.
On the passenger side, regard less of safety
be lt use, the front passenger fronta l airbag
will be turned off i f the e lectrical capac itance
measured by the capacitive passenger detec­
tion system on the front passenge r seat is less
than the amount programmed in the electron­ ic control unit. The front passenger frontal air­
bag will also 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 one
yea r of age i n one of the child sea ts that was
used to cer tify the Advanced Airbag System
under Federal Motor Vehicle Safety Standard
208 . The
PASSENGER AIR BAG OF F light
comes on and stays on to tell you when the
front Advanced A irbag System on the passen­
ger s ide has been turned off¢
page 153.
A WARNING
To reduce the risk of injury when a n 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 inj ury is much higher.
- You wi ll 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- flates
-even w ith an Advanced A irbag

More important things to know about
front airbags

q :r:
iZ
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 designed 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 positioned 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 adj usted .
Bec ause airbags inflate in the bli nk of an eye
with great force, th ings you have on your lap
or have p laced on the seat co uld become dan ­
gerous pro jecti les, and be p ushed into 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 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 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
IIJI,

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
P AS SENGER A IR BA G OFF light
c:> page 153 and how they work 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 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
with great force in the blink of an eye
c:> page
142 .
A WARNING
A child in a rearward-facing child seat in­
stalled on the front passenger seat will be
-
A irbag system 15 1
seriously injured and can be killed if the
front airbag inflates -even w ith an Ad­
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
P A SSENGER AIR BAG OFF light
does not come on and stay on, immed i­
ately insta ll the rear-fac ing child seat in a
rear seating position and have the airbag
system inspected by your A udi dealer.
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
move into the area of the s ide a irbag or
the front a irbag during braking or in a
