Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
A irbag System in it. These parts incl ude t he
c a pac itive passenger de te ct ion sys tem, wir
ing, b racke ts, and more . The cont ro l uni t
monitors the system o n the front passenger
seat when the ign ition is switched on and
turns the airbag indicator light on w hen a
malfunct ion in the one of the system compo
nents is detected ¢
page 162. Beca use the
fro nt passenge r seat contains important parts
of the Advanced Airbag System, you must
take care to p revent it from bei ng damaged.
D amage to the seat may preven t the Ad
vanced A irbag System for the front passenger
seat from doing its job in a crash .
The front Advanced Airbag System
consists of the following:
-Crash sensors in the front of the veh icle tha t
measure ve hicle acceleration/dece le ration
to provide information to the Advanced Air bag System about the severity of the crash.
A irbag system 157
- An elect ron ic contro l unit, with integrated
crash sensors fo r front and side impacts .
T he control un it "decides" whether to f ire
the front a irbag s based on the informat ion
received from the crash sensors. The control
unit also "decides" whether the safety belt
prete nsione rs should be act iva ted .
- An Advanced A irbag w it h gas generator and
cont ro l valve for the driver ins ide the steer
ing wheel h ub.
- An Advanced A irbag w ith gas generator and
cont ro l valve inside the instrument pa nel for
the front passenger .
- A capacit ive passenger detection system un
de rneath the front passenger seat cover .
This system measu res the ele ct rical capac i
t ance of the perso n in the seat. The informa
t ion regis tered is se nt cont inuo usly to the
elec tronic con trol un it to regu late dep loy
ment of the front Advanced A irbag on the
passenger side.
-An airbag monitoring system an d ind icator

-A senso r in each front seat registers the dis
tance between the respective seat a nd the
steering whee l or instrument panel. The in
formation registered is sent cont inuo usly to
the electron ic contro l unit to regulate de
ployment of the front Adva need A irbags .
- The

-Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
driver seat from the vehicle.
- Never remove the upholstery from the
front passenger seat.
- Never disassemble or remove parts from
the seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or put them on the seat. The capacitive
passenger detection mat in the front
passenger seat will not function properly
if it is punctured .
- Never carry things on your lap or carry
objects on the front passenger seat.
Such objects can influence the capaci
tance registered by the capacitive pas senger detection system, so that incor
rect information is provided to the airbag
control unit.
- Never store items under the front pas
senger seat. Parts of the Advanced Air
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper
ly.
- Never place seat covers or replacement upholstery that have not been specifical
ly approved by Audi on the front seats.
- Seat covers can prevent the Advanced
Airbag System from recognizing child re
straints or occupants on the front pas
senger seat and prevent the side airbag
in the seat backrest from deploying prop
erly .
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys
tem on this seat.
- Never use cushions, pillows, blankets, or
similar items on the front passenger
seat. The additional layers prevent the
capacitive passenger detection system
from accurately measuring the capaci
tance of the child safety seat and/or the
person on the seat and thus keep the Ad- vanced Airbag System from working
properly.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device or power inverter) on the
front passenger seat if the device is con nected to the 12-volt socket or the ciga
rette lighter socket. Such devices can in
fluence the capacitance registered by the
capacitive passenger detection system,
so that incorrect information is provided
to the airbag control unit.
- If you must use a child restraint on the
front passenger seat and the child re
straint manufacturer's instructions re
quire the use of a towel, foam cushion or
something else to properly position the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re
straint is installed on the front passen
ger seat.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi
ately install child restraint in a rear seat
ing position and have the airbag system
inspected by your Audi dealer.
_& WARNING
If the front passenger seat gets wet, dry it
immediately.
- If liquid soaks into the front passenger
seat, this can keep the airbag system
from working properly and may, for in stance, deactivate the passenger frontal
airbag. If this happens, the
PASSENGER
AIR BAG OFF
light will come on and stay
on together with the airbag indicator light
fl in the instrument cluster .
- If liquid is pooled on the seat, but has
not soaked in, this may also keep the air
bag system from working properly and
cause the passenger frontal airbag to be
enabled (turned on), even though there
is a properly installed child restraint sys
tem on the seat. Wet towels or other wet
things on the seat cushion can have the
same effect. If the front passenger
frontal a irbag is turned on, the
PASSEN
GER AIR BAG OFF
light light will go out.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side ai rbags supplement the pro tection of
fe red by the fro nt three -point safety be lts
with pretensioners and load limiters and the
adj ustab le head restra ints to he lp reduce the
risk of injury in a wide range of accident and
crash situations. 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 act ivation of the safety be lt preten
sioners depend on the decelerat ion measured
by the crash sensors and registered by the
electronic control un it. The amount of infla
tion of the front airbags can also be adapted
to the front seat position, depending on the d istance between the respe ctive front seat
and the steering whee l or inst rument panel as
registered by sensors in the seats. Crash se
verity depends on speed and deceleration as
well as the mass and stiffness of the vehicle
or object invo lved in the crash .
On the passenger s ide, regard less of safety
be lt use, the front passenger fronta l airbag
will be t urned off if the electrical capacitance
measured by the capacitive passenger detec
tion system on the front passenger seat is less
than the amount programmed in the electron
ic control unit . The front passenger fronta l air
bag will a lso be turned off if the capac itance
measured by the system for the front passen
ger seat eq ua ls tha t of an infant o f abo ut one
year of age in one o f the child seats that was
used to cert ify the Advanced Airbag System
under Fede ral Motor Vehicle Safety Standard
208 . The

A WARNING
To reduce the risk of injury w hen an airbag
in flates, always wear safety be lts p roperly.
- If you are unrestra ined, leaning forward,
sitt ing s ideways or out of pos ition in any
way, your risk of injury is much higher.
- You will a lso receive serious injuries and
could even be killed if you are up aga inst
the airbag o r too close to it when it in
flates -even w it h an Advanced A irbag

More important things to know about
front airbags
F ig. 162 In flated front a irbags
Safety belts are important to help keep front
seat occupants in the proper seated position
so that ai rbags can unfold p roper ly and pro
vide s upplementa l pro tect ion in a fron tal col
lis ion .
T he front airbags are des igned to provide ad
di tional protection fo r the chest and face of
the d river a nd the front seat passenger when :
- safety belts are worn properly,
- the seats have been positioned so that the
occupant is properly seated as far as poss i
b le from the airbag,
- and the head restraints have been properly adjusted .
Because airbags inflate in the blink of an eye
with great force, things you have on your lap
or have placed on the seat could become dan
gerous p rojecti les, and be pushed into you if
the a irbag inf lates.
When an airbag deploys, fine dust is re leased.
This is norma l and is not caused by a fire in .,,.
160 Airbag sys te m
the vehicle. This dust is made up most ly of a
powder used to lubricate the airbags as they
deploy . It cou ld irritate sk in .
I t is important to remember that whi le the
supp lemental airbag system is designed to re
duce the likelihood of serious injuries, other
in ju ries, for example swelling, bruising and
minor abrasions, can also happen when air
bags inflate. Airbags do not protect the arms
or the lower parts of the body . Front airbags
supplement the three-poi nt safety belts only
in some frontal co llisions in which the vehicle
dece lera tion is high enough to deploy the air
bags.
Front airbags will not d eploy:
- if the ignit ion is switched off when a crash
occurs,
- in s ide collisions,
- in rear-end collisions,
- in ro llovers,
- when the crash deceleration measured by
the airbag system is less than the minimum
threshold needed for airbag deployment as
registered by the electronic control unit.
Th e front pa ssenger airbag al so will not
d epl oy :
-when the front passenger seat is not occu
pied,
- when the electrical capacitance measured by
the capacitive passenger detection system
for the front passenger seat indicates that
the passenger side frontal airbag must be
switched off by the electronic control unit (the
PASSENGER A IR B AG OFF light
c::> page 162 and how they wo rk comes on
and stays on).
.&_ WARNING
Sitting in the wrong position can inc rease
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 position,
must not lean against or place any part of their body too close to the area where
the airbags are
located .
- Occupants who are unbelted, out of posi
tion or too close to the airbag can be se
rious ly injured by an airbag as it unfolds
with great force in the blink of an eye
c::> page 151 .
.&_ WARNING
--A child in a rearward-fac ing ch ild seat in -
stalled on the front passenger seat will be
se riously inju red and can be killed if t he
front ai rbag inflates - even w ith an Ad
vanced A irbag System.
- The inflating airbag will h it the c hild seat
or infant car rier with great force and will
smash the child sea t and chi ld against
the backrest, center armrest, door or
roof.
- Always install rear -fac ing chi ld seats on
the rear seat.
- If you m ust insta ll a rearward fac ing
chi ld seat on the front passenger seat
because of exceptional circumstances
and the PAS SENGER AIR BAG O FF light
does not come on and stay on, immed i
ately install the rear-facing child seat in a rear seat ing pos ition and have the airbag
system inspected by you r Audi dealer .
.&_ WARNING
= -
Objects between you and the airbag will
i ncrease the r is k of injury in a crash by in
terfering with the way the a irbag unfolds
or by be ing p ushed in to you as the airbag
i nflates.
- Neve r hold things in yo ur hands or on
your lap when the veh icle is in use.
- Never transpo rt items on o r in the a rea
of the front p assenger sea t. Objects
could move into the a rea of the front air
bags during braking or other sudden ma
neuvers and become dangero us projec
tiles that can cause ser ious personal in-
jury if the a irbags inf late. ..,.
-Never place or attach accessories or o th
er objects (such as cup hol ders, tele
phone brackets, large, heavy or bulky ob
jects) on the doors, over or near the area
marked ''AIRBAG" on the steering wheel,
instrument panel, seat backrests or be
tween those a reas and yourself. These
objects co uld cause injury in a crash, es
pecially when the airbags inflate .
- Never recline the front passenger's seat
to transport objec ts. Items can also
move into the area o f the side airbag or
the front airbag during braking or in a
sudden maneuver . Objects near the air
bags can become project iles and cause
injury, part icularly when the seat is re
cl ined .
- Never place or transport ob jects on the
front passenger seat. Objects on the
front passenger seat could cause the ca pacitive senso r in the seat to s ignal to
airbag system that the seat is occupied
by a person when it in fa ct is not, o r that
the person on the se at is he avier than he
or she actually is. The change in electric
capacitance beca use of such objects can
cause the passenger front airbag to be
turned on when it sho uld be
off, or can
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout objects on the seat.
- Always make sure that there is nothing
on the front passenger seat that will
cause the capacitive passenge r detection
system in the s eat to s ignal to the A irbag
System that the seat is oc cupied by a
pers on when it is not, or to sign al that it
is occupied by someone who is heavier

Repair, care and disposal of the airbags
Parts of the airbag system are installed at
many different places on your Audi. Installing,
removing, servicing or repairing a part in an
area of the vehicle can damage a part of an
airbag system and prevent that system from
working properly in a collision.
There are some important things you have to know to make sure that the effectiveness of
the system will not be impaired and that dis
carded components do not cause injury or pol
lute the environment.
A WARNING
Improper care, servicing and repair proce
dures can increase the risk of personal in
jury and death by preventing an airbag from deploying when needed or deploying
an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way .
- Never attach any objects such as cup
holders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de
ploy and protect properly.
Airbag system 165
- Never repair, adjust, or change any parts
of the airbag system.
- All work on the steering wheel, instru
ment panel, front seats or electrical sys
tem (including the installation of audio
equipment, cellular telephones and CB radios, etc .) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work
shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace
ment upholstery over the front seat
backs that have not been specifically
approved by Audi.
- Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can deploy only once .
After an airbag has been deployed, it
must be replaced with new replacement
parts designed and approved especially
for your Audi model version. Replace ment of complete airbag systems or air
bag components must be performed by
qualified workshops only. Make sure that
any airbag service action is entered in
your Audi Warranty
