Important information
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints . For
airbags to do their job, occupants must always
properly wear their safety belts and be in a prop­ er seating position.
For your safety and the safety of your passen­
gers , before driving off, always :
.,. Adjust the driver's seat and steering wheel
properly ~ page 180,
.,. Adjust the front passenge r's seat properly
~ page 181,
.,. Wear safety belts p roperly ~ page 189,
.. Always properly use the proper child restraint
to protect chi ldren
~ page 216.
In a coll is ion airbags must inflate within the blink
of an eye and with considerable force. The sup­
p lemental airbags can cause injuries if the driver
or the front seat passenger is not seated proper ·
ly. T herefore in order to help the airbag to do its
job, it is important, both as a dr iver and as a pas­
senger to sit properly at all t imes .
By keeping room between your body and the
steering whee l and the front of the passenger
compartment, the a irbag can inflate fully and
completely and provide supplemental protect ion
in certain frontal
coll isions ¢ page 180, Correct
passenger seating positions .

operation of the seat adjustment controls
¢page 46.
It's especially important that children are proper ­
ly restrained
¢page 216 .
There is a lot that the driver and the passenger
can and must do to help the ind iv idual safety fea­
tures installed in your Audi work together as a
system .
Proper seating posit ion is important so that the
front airbag on the driver side can do its job. If
you have a physical impairment or cond ition that
prevents you from s itting properly on the driver
seat with the safety be lt properly fastened and
194 reaching
the pedals, or if you have concerns with
regard to the function or operation of the Ad­
vanced Airbag System, please contact your au ­
thori zed Audi dea ler or qualified workshop, or
ca ll Audi Customer Relations at 1-800-822-2834
for poss ible modifications to your vehicle .
When the airbag system dep loys, a gas generator
will fill the airbags, break open the padded cov­ ers, and inflate between the steering wheel and
the driver and between the instrument panel and
the front passenger . Th e a irbags w ill deflate im­
med iate ly after deployment so that the front oc­
cupants can see t hrough the windsh ield aga in
without interruption.
All of th is takes place in the blink of an eye, so
fast that many people don't even realize that the
a irbags have deployed. The airbags also inflate
with a great deal of force and nothing should be
in the ir way when they deploy. Front airbags in
combination with properly worn safety belts slow
down and limit the occupant's forward move­
ment . Together they help to prevent the driver
and passenger from hitting parts of the inside
the vehicle while reducing the forces acting on
the occupant during the crash . In this way they
help to reduce the risk of injury to the head and
upper body in the crash . Airbags do not protect
the arms or the lowe r parts of the body.
Both front airbags will not inflate in all frontal
collisions . The triggering of t he a irbag system de­
pends on the vehicle deceleration rate caused by
the collis ion and regis tered by the electronic con ­
trol unit . If this rate is be low the refe rence value
programmed into the control unit, the airbags
will not be triggered, even tho ugh t he car may be
badly damaged as a resu lt of the co llision . Vehi­
cle damage, repair costs or even the lack of vehi­
cle damage is not necessarily an indication of
whether an a irbag should inflate or not.
Since the circumstances wi ll vary considerab ly
between one collision and another, it is not possi ­
ble to define a range of veh icle speeds that will
cover every poss ible kind and angle of impact
that w ill always trigger the airbags . Important
factors include, for example, the nature (hard or
soft) of the object which the car hits, the angle of
im pact , vehicle speed, etc. The front airbags will

adjustment range, as far away from the air­
bag as possib le, before insta lling the for­
ward-facing child restra int.
- Always make sure that the safety belt upper
anchorage is beh ind the child restraint and
not next to or in front of the chi ld restraint
so that the safety belt will be properly pos i­
t ioned.
- Always make sure that there is nothing on
the front passenger seat that w ill cause the
capacit ive passenger detection system in
the seat to signa l to the Airbag System that
the seat is occupied by a person w hen it is
not, or to sign al that it is occ upied by some­
one who is heavier than t he pe rson actua lly
sitting on the seat . The presence of addi­
tiona l objects could ca use the passenge r
front airbag to be turned on when it shou ld
be off, or could cause the airbag to work in a
way that is different from the way it would
have worked wi tho ut the object on t he seat .
- Make sure that the

Advanced Airbag System components
The front passenger seat in you r vehicle has a lot
of very impo rtant parts of the Advanced Airbag
Sys tem in it. These pa rts in cl ude the capaci tive
passenger detection system, w iring, brac kets,
and more. The control unit monitors the system
on the front passenger seat when the ignition is
switched on and turns the airbag indicator light
on when a malfunct ion in the one of the system
components is detected
¢ page 206. Because
the front passenger seat contains important
pa rts of the Advanced Airbag System, you must
take ca re to prevent it from be ing damaged .
D amage to the seat may p reve nt the Advanced
A irbag System fo r the fron t passenger seat from
doi ng its job in a crash.
The front Advanced Airbag System consists
of the following :
-Cr ash sensors in the front of the vehicle t hat
measure vehicle accelerat ion/dece lerat ion to
Airbag syste m
prov ide information to the Advanced A irbag
System about the severity of the cras h.
- An electronic contro l uni t, with integrated
cras h sensors for front and side impacts . The
control unit "decides" whether to fire the front
airbags based on the information rece ived from
the crash sensors . The control unit also "de­
cides" whether the safety belt pretensioners
should be activated.
- An Advanced A irbag w it h gas generator for the
driver inside the steering wheel hub .
- An Advanced A irbag w ith gas generator inside
the instrument panel for the front passenger.
- A capacit ive passenger detection system under ­
neat h the front passenger seat cover. This sys­
tem meas ures the e lectr ica l capacitance of the
person in the seat. The informat ion registered
is sent cont inuously to the elect ronic contro l
un it to reg ulate dep loymen t of the front Ad­
vance d Airbag on the p assenger side.
- An airbag monitor ing system and ind icator
ligh t
El in the inst rument cl uste r.
- A sensor in each front seat registe rs the d is­
t ance betwee n the respective seat and the
s teer ing whee l o r i nst rument p anel. The infor­
mation registered is sent con tinuous ly to the
elect ronic contro l unit to regu late dep loyment
of the front Advanced Airbags .
- The
PASSENGER AIR BAG OFF ~; lig ht comes
on and stays on in the
headliner¢ page 206,
fig. 164 and tells you when the front Advanced
Airbag on the passenger side has been turned
off.
- A sensor in the safety be lt latch for the driver
and for the front seat passenger that senses
whether that safety be lt is latched or not and
transmits this information to the e lectronic
control un it .
A WARNING
-
Damage to the front passenge r seat can pre­
vent the front airbag from wo rk ing prope rly.
- Imp roper repair or d isassembly of the front
passenger and driver seat will p reve nt the
Advanced A irbag Sys tem from f unct io ni ng
p roperly .
