Airbag syste m
The additio na l l ayers prevent the capacitive
passenger detection system from accurately
measuring the capac itance of the ch ild safe
ty seat and/or the person on the seat and
thus keep the Advanced Airbag System from
working p roperly.
- Never place or use any electrical device (such as a laptop, CD player, elect ronic
games dev ice, power inverte r or seat heater
for child seats) on the front passenger seat
if the device is connected to the 12-vol t
socket or the cigarette lighter socket . S uch
devices can infl uence the capacitance regis
tered by the capacitive passenger detection
system, so that incorrect information is pro
vided to the airbag control unit.
- If you must use a c hild restraint on the front
passenger seat and the child restraint man
ufacturer's instructions require the use of a
towel, foam cushion or something else to prope rly position the ch ild restraint, make
certain that the
PASSENGER AIR BAG OFF

the chi ld restraint is installed on the front
passenge r seat .
-If the PASSENGER AIR BAG OFF~; light
does not come on and s tay on , immediate ly
ins tall child restra int in a rea r seating posi
tion and have the airbag system inspected
by you r A udi dealer.
_& WARNING
If the front passenger seat gets wet, dry it im
mediately.
- If liquid soaks into the front passenger seat,
this can keep the a irbag system from work
ing prope rly and may, for instance, deact i
vate the passenger frontal airbag. If this happens, the
PASSENGER AIR BAG OFF~;
light will come on and stay on togethe r with
the a irbag ind icator

How the Advanced Airbag System
components work together
The front Advanced A irbag System and the side
airbags supp lement the p rotection offered by the
front three-point safety be lts and the adjustable
head restraints to he lp reduce the risk of injury in
a wide range of accident and crash situat ions. Be
sure to read the important i nformat ion about
safety and heed the WARNINGS in this chapter .
Deployment of the Advanced A irbag System and
the activation of the safety belt pretensioners de pend on the dece leration measured by the crash
sensors and registered by the elec tronic contro l
u nit . Crash severity depends on speed and decel
e ration as well as the mass and stiffness of the
vehicle or object invo lved in the cras h.
On the passenger side, regard less of safety be lt
u se, the front passenge r frontal airbag will be
turned off if t he e lectr ica l capaci tance m easured
by the capaci tive p assenge r detection system o n
t h e fron t passenger sea t is less th an the amou nt
programmed in t he e lec tronic cont ro l unit. The
front passenger frontal airbag wi ll also be turned
off if the capacitance measured by the system for
the front passenger seat equals that of an infant
of about one year of age in one of the child seats
that was used to certify the Advanced Airbag Sys
tem under Federal Motor Vehicle Safety Standard 208. The

_& WARNING
To reduce the ris k of injury when an airbag in
f lates, always wea r safety belts prope rly.

airbags
F ig. 2 40 Inflated front airbags
0 0 M
-.a ;z
Safety belts are impo rtant to help keep front
seat occupants in the proper seated position so
that airbags can unfold properly and provide sup p lemental protection in a frontal collision.
The front airbags are designed to provide addi
tional protect ion for the chest and face of the
driver and the front seat passenger when:
- safety belts are worn properly
- the seats have been positioned so that the oc-
cupant is properly seated as far as possible
from the airbag
- and the head restraints have been properly ad-
justed
Because airbags inflate in the blink of an eye w ith
great force, things you have on your lap or have p laced on the seat could become dangerous pro
jectiles, and be pushed into you if the airbag in flates .
When an airbag deploys, fine dust is released.
This is normal and is not caused by a fire in the
veh icle. 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 remember that while the sup
plemental airbag system is designed to reduce
the likelihood of ser ious injuries, other injuries,
for example swelling, bruising and minor abra -
Airbag sys tem
sions, can also happen when airbags inflate. Air
bags 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 airbags .
Front airbags will not depl oy :
- if the ign ition is switched off when a crash oc-
curs
- in side co llisions
- in rear-end coll isions
- in rollovers
- when the crash deceleration measured by the
ai rbag system is less than the m inimum thresh
old needed for airbag dep loyment as registe red
by the electronic control un it
The front pass enge r airbag also w ill not
deploy:
- when the fron t passenger seat is not occupied,
- when the e lectr ical capacitance measured by
t he capacit ive passenger detection system for
the front passenge r seat ind icates that the pas
senger side frontal airbag m ust be switched off
by the electronic control unit (the

_& WARNING
Sitting in the wrong position can increase the
risk of ser ious injury in crashes.
- To reduce the risk of injury when the a irbags
inflate, the driver and passengers must al
ways sit in an upright posit ion, must not
lean aga inst or place any part of their body
too close to the area where the airbags are lo cated.
- Occupants who are unbelted, out of posit ion
or too close to the airbag can be serio usly
inj ured by an airbag as it unfolds wi th g reat

Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash . For example, using tire-r im
comb inat ions not approved by Audi, lowering the
ve hicl e, chang ing the s tiffness of the suspens io n,
in clud ing the spr ings, suspens ion str uts, shock
absor bers et c. can change the forces that are
measured by the airbag sensors and sent to the
e lectronic contro l unit. Some suspension changes
can, for example, increase the force levels meas
ured 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 ki nds of
changes may reduce the fo rce levels meas ured by
the sensors and prevent the airbag from deploy in g when i t should .

A WARNING ,-
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in

The airbag system is monitored electronically to make certa in that it is functioning properly at all
times. Each time you turn on the ignit ion, the air
bag system ind icator light will come on for a few
seconds (self diagnostics).
The s ide a irbag system supplements the safety
be lts and can help to reduce the risk of injury to
the dr iver's, front and rear* passenger 's upper
torso on the side of the vehicle that is struck in a
s ide collision . The airbag dep loys only in side im
pacts and on ly wh en the vehicle acceleration reg
iste red by the control unit is high enough . If this
rate is below the reference value programmed in
t o the control unit, the side airbags w ill not be
tr iggered , even though the car may be badly
damaged as a result of the collision .
It is not pos
sib le to define an airbag tr igger ing range that
w ill cover every possib le ang le of impact , since
the c ircumstances wi ll vary cons iderably between
one co llision and another . Important factors in

Side airbags deploy instantly and can help reduce the risk of upper torso injuries for occu
pants who are properly restrained.
Fig. 243 Inflated side airbags on left side of vehicle , rear
side airbag optiona l equipment
When the system is triggered, the airbag is filled
with propellant gas and breaks through a seam in
the seat surface area.
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
p leme ntal side airbag could injure you if your
seating position is not proper or upright or if
items are located in the area where the supple
mental side airbag expands. This applies espe
cially to children~
page 295, Child safety. Sup
plemental side airbags inflate between the occu
pant and the door panel on the side of the vehicle
that is struck in certain side collision
~fig. 243.
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 deploys.
This is normal and does not mean there is a fire
in the vehicle .
Airbag system
Important safety instructions on the side
airbag system
Airbags are only supplemental restraints. Always
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 provide supplemental
protection.
A WARNING
An inflating side airbag can cause serious or
fatal injury. Improperly wearing safety belts
and improper seating positions increase 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 supple
mental 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 replacement
upholstery over the front seatbacks that
have not been specifically approved by
Audi.
- Never use additional seat cushions that
cover the areas where the side airbags de ploy.
- Damage to the original seat covers or to
the seam in the area of the side airbag
module must always be repaired immedi
ately by an authorized Audi dealer.
-
- Objects between you and the airbag can in
crease the risk of injury in an accident by in
terfering with the way the airbag unfolds or _,.
291
Airbag syste m
by being pushed into you as the airbag in
flates.
- Never p lace or attach accessories or other
objects (such as cupho lders, te lephone
brackets, or even large, bulky objects) on
the doors, over or near the area marked
"AIRBAG" on the seat backrests.
- Such objects and accessories can become
dangerous projectiles and cause in ju ry
when the supplemental side airbag de ploys.
- Never carry any objects or pets in the de ployment space between them and the
airbags or allow children or other passen
gers to travel in this posit ion.
- Always use the built-in coat hooks* only for
lightweight clothing. Never leave any heavy
or sharp-edged objects in the pockets that
may interfere w it h side airbag deployment
and can cause personal i njury in an accident.
- Always prevent the side airbags from being
damaged by heavy objects knocking against
or hitting the sides of the seatbacks.
- The airbag system can only be triggered
once. If the airbag has been triggered, the
system must be replaced by an author ized
Audi dealership.
- Damage (cracks, deep scratches etc.) to the
orig inal seat covers or to the seam in the
area of the side a irbag mod ule m ust always
be repa ired immed iate ly by an authorized
Audi dealer .
-If children are sea ted improperly, their r is k
of injury increases in the ca se of an ac ciden t
