the passenger side may deploy (the PASS EN­
GER AIR B AG OFF
light does not come on).
For exa mple, the ai rba g may d epl oy if :
- a small child that is heavier than a typical 1
year-o ld child is on the front passenger seat
(regardless of whether the child is in one of
the ch ild seats listed
¢ page 172),
- a ch ild who has outgrown child restra ints is
on the front passenge r seat.
If the front passenger airbag is turned off, the
P A SSENGER AIR BAG OFF light in the center
of the instrument panel w ill come on and stay
on.
If the front passenger airbag deploys, the
Federal Standard requires the airbag to meet
the "low risk " deployment criteria to help re·
duce the risk of injury through interaction
with the airbag . "Low risk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the electronic control unit
r=> page 156.
Alwa ys r em emb er: E ven tho ugh you r vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
back seat . Please be sure to read the impor­
tant information in the sect ions that follow
and be sure to heed all of the WARNINGS .
A WARNING
To reduce the risk of injury when an airbag
inflates, always wear safety belts properly .
- If you are unrestrained, lean ing forward,
sitting sideways or out of position in any
way, your risk of injury 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 -even with an Advanced Airbag
r::!v page 144.
A WARNING
A child in a rearward-facing child sea t in­
stalled on the front passenger sea t will be
ser iously injured and can be killed if the
-
A irbag system 15 1
front airbag inflates - even with an Ad·
vanced Airbag System .
- Altho ugh the Advanced Airbag System in
your veh icle is designed to turn off the
front airbag when a rearward-facing
child restraint has been installed on the
front passenger seat, nobody can abso ­
lutely guarantee that deployment is im­
possible in all conceivable s ituations that
may happen dur ing the usefu l life of your
veh icle.
- The inflating airbag will h it the ch ild seat
or infant carrier with grea t force and will
smash the child seat and child against
the backrest, center armrest, door, or
roof.
- Always install rearward -facing chi ld re­
straints on the rear seat .
- I f you must install a rearward fac ing
child seat on the front passenger seat
because of exceptional circumstances
and the
PASSENG ER AIR BAG O FF light
does not come on and stay on, immed i·
ately install the rear-fac ing child seat in a
rear seat ing pos ition and have the airbag
system inspected by your Audi dealer .
A WARNING
If, in except ional circumstances, you must
install a forward-facing child restraint on
the front passenge r's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacture r fo r u se on a front seat
with a passenger front and s ide a irbag.
- Never put the fo rward-faci ng child re­
straint up against or ve ry near the instru­
ment panel.
- Always move the passenge r seat into its
rearmost pos ition in the seat's fore and
aft ad justment range, as fa r away from
the airbag as possible before installing
the forward-fac ing chi ld restraint . The
backrest must be adj usted to an upright
position.
- Always make sure that there is nothing
on the front passenger seat that will •

cause the capacitive passenger detection
system in the seat to s ignal to the A irbag
System that the seat is occupied by a person when it is not, or to signal that it
is occupied by someone who is heavier
than the person actually s itting on the
seat. The presence of additional objects
cou ld cause the passenger front airbag
to be t urned on when it sho uld be off, or
cou ld cause the airbag to work in a way
that is different from the way it wou ld

on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
lot of very important parts of the Advanced
A irbag System in it . These parts include the
capacitive passenger de tect ion system, wir­
ing, b ra ck ets, and more. The cont ro l unit
monitors the system on the front passenger
seat when the ign ition is switched on and
turns the airbag indicato r light on when a
malfunction in the one of the system compo­
nents is detected¢
page 157 . Because the
fro nt passenger seat contains important parts
of the Advanced Airbag System, you must
take care to prevent it from being damaged .
Damage to the seat may prevent the Ad­
vanced A irbag System for the front passenger
se at from doing i ts job in a c rash.
The front Advanced Airbag System
consists of the following:
- Crash sensors in the fro nt of the ve hicle that
m easure ve hicle accelera tion/de celera tion
to provide info rmation to the Advanced Air­
bag System abo ut the seve rity of the crash.
- An electronic cont ro l u nit, with integrated
c rash sensors for front and side impacts.
The cont ro l unit "decides" whether to fire
the front airbags based on the information received from the crash sensors. The contro l unit also "decides" whether the sa
fety belt
pretensioners sho uld be activated.
- An Advanced A irbag w ith gas generato r for
the driver inside the steering wheel h ub.
- An Advance d Airbag w ith g as generato r in­
side the inst rument panel for the front pas ­
senger.
- A capacit ive passenger detection system un­
de rneath the front passenger seat cover .
This system meas ures the electrical capac i­
tance of the person in the seat. The informa ­
tion registered is sent cont inuo usly to the
electronic control un it to regu late deploy­
ment of the front Advanced A irbag on the
passe nger side .
- An airbag monitor ing system and indicator
light in the instrument cluster¢
page 156 .
-A sensor in each front seat registers the dis­
tance betwee n the respective seat and the
steer ing whee l o r inst rument panel. The in­
formation registered is sent cont inuous ly to
t he ele ct ron ic contro l unit to regula te de­
p loyment of the front Adva nced A irb ags .
- The
PASSENGER AIR BAG OFF light comes
on and stays on in the center of t he instr u­
ment p anel ¢
page 217 and t ells yo u when
the fron t Advanced Airbag on the passenge r
side has been turned off.
- A sensor in the safety be lt latch for the driv ­
er and for the front seat passenger that
senses whether t hat safety belt is latched or
not and transmits this information to the
electronic control un it.
A WARNING
Damage to the front passenger seat can
prevent the front airbag from wor king
p roperly.
- Improper repair or d isassembly of the
front passenge r and dr iver sea t will pre­
vent the Advanced Airbag System from
functioning p roperly.
- Repairs to the front passenge r seat must
be pe rformed by qualified and p roperly
trained workshop personnel.
- Never remov e the front passenger o r
d river seat from the vehicle.

154 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 157.
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

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

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
Q page 157 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
Qpage 146 .
A WARNING
A child in a rearward-facing child seat in­
stalled on the front passenger seat will be

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 safety seat on the front passenger
seat because of exceptional c ircumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and s tay on, im­
mediately install the rearward-fac ing
child safety seat in a rear seating posi­
tion and have the airbag system inspect­
ed by your authorized Audi dealer.
A WARNING
Objects between you and the airbag will increase the r isk 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 i f the a irbags inflate.
- Never p lace or a ttach accesso ries o r oth­

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 161
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. 133 Driver's kn ee airbag
The dr iver knee airbag is in the instrument
panel underneath the steering wheel
¢
fig. 133, 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 154, 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¢
page 135, General notes. ..,_

162 Airbag system
Remember too, airbags will deploy only once
and on ly in certain k inds of accidents -your
safety belts are always there to offer protec­
tion in those accidents in which airbags are
not supposed to deploy or when they have al­
ready deployed, for example when your veh i­
cle strikes or is struck by another after the
first coll is ion .
This is just one of the reasons why an airbag is
not a substitute for the safety belt . The airbag
system works most effectively when used with
the safety belts . Therefore, always wear your
safety be lts correctly .
It is important to remember that while the
supplemental knee airbag system is designed
to reduce the likelihood of serious injuries,
other injuries , for example , swell ing, bruising
and minor abrasions and friction burns can al­
so occur when an airbag inflates.
The knee airbag system basically consists
of:
- The elec tronic con trol module
- T wo inflatab le airbags (airbag and gas gen-
erator), one fo r the driver and one for the
front passenger
- T he airbag indicator light in the instrument
panel
The knee airbag system will not deploy:
-when the ign ition is switched off
- in frontal collisions when the deceleration
measured by the control unit is too low
- in side collisions
- in rear-end collisions
- in rollovers
- i n the event of a system malfunction (warn-
i ng/indicator light is on)
Q page 21.
.8, WARNING
-Safety belts and the airbag system can
only provide protection when occupants
are in the proper seating posit ion
Q page 154.
-If the airbag indicator light¢ page 21
comes when the vehicle is be ing used,
have the system inspected immediately
-
by your authorized Audi dealer. It is pos­
sible that the airbag will inflate when it
is not supposed to, or will not inflate
when it should .
How knee airbags work
Applies to vehicles: wi th knee airbags
The risk of injury to the leg area can be re ­
duced by fully inflated knee airbags.
Fig . 134 Inflated a irbags protecting in a fronta l co lli­
sion
The knee airbag system has been designed so
that the airbags for the driver and front pas ­
senger deploy in certa in but not all frontal
collisions.
If the front airbags dep loy, the knee airbags
also dep loy in frontal collisions when the de­
ployment threshold stored in the control unit
is met.
When the system deploys, the airbags fill
with a compressed propellant gas, and inf late
between the lower part of the instrument
panel and the driver and the lower part of the
instrument panel and the front passenger
Qpage 154, fig. 131 .
Although they are not a soft pillow, they can
"cushion" the impact and in th is way they can
help to reduce the risk of injury to the lower
extremit ies .
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
i nflate with a great deal of force and it is im­
portant for occupant safety that nothing
shou ld be in their way when they deploy. ..,.
