Advanced front airbag system
Your veh icle is equipped w it h a front Advanced
A irbag System in compliance with U nited
States Federal Motor Vehicle Safety Standard
208 as applicab le at the time your vehicle was
manufactured.
The front Advanced Airbag System supple ments the safety belts to provide add it ional
p rotection fo r th e driver's and front passeng
e r' s heads and upper bodies in fronta l crashes.
The airbags in flate only in frontal impacts
when the vehicle dece le rat ion is high enough .
The front Advanced A irbag System for the
fro nt sea t occ upants is no t a subs titu te for
your safety bel ts. Ra ther, it is p art of t he over
all occupant restraint system in your veh icle.
A lways remember that the airbag system can
only help to protect yo u, if you are s itting up
right, wearing yo ur safety belt and wearing it
properly . This is why you and your passengers
must always be properly restrained, not just
because the law requires you to be .
The Advanced Airbag System in your veh icle
has been certified to meet the " low r isk" re
qu irements for 3 and 6 year-o ld childre n on
the passenge r side and very small adu lts on
A irbag system 143
the d river side . The low risk deployment c rit e
ria are intended to help reduce the risk of in
ju ry through interaction with the front airbag
that can occur, for example, by being too close to the steering wheel and instrument
panel when the airbag inflates.
In add ition, the system has been certified to
comply with the "s uppression" requirements
of the Safety Standard, to turn off the front
airbag for infants 12 months old and younger
who are res trained on the fro nt passenger
seat in child rest raints that ar e listed in the
Standard
¢ page 165, Child restraints and
Advanced front airbag system.
"Suppress ion " requires the front a irbag on the
passenger side to be turned off if:
- a child up to abo ut one year of age is re
strained on the front passenger seat i n one
of the rear-fac ing o r forward-facing infant
restrai nts listed in Federal Motor Vehicle
Safety Standa rd 208 wi th wh ich the Ad

If the tota l electrical capacitance registe red
on the front passenger seat is more than that
of a typ ica l 1 year-old, but less than the
weight of a small adult, the front a irbag on
the passenger side may deploy (the
PA SSE N

li ght does not come on).
For e xample , the airbag m ay deploy 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 chi ld seats listed
¢ page 165),
-a chi ld who has outgrown child restraints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light in the center
of the instrument panel wi ll come on and stay
on.
If the front passenger airbag deploys, the
F ederal Standard requires the airbag to meet
the " low risk" deployment criteria to help re
d uce 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 un it
¢ page 149 .
Alw ays rem ember : Even though your vehicle
is equipped with Advanced Airbags, the safest
place 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 a ll of the WARNINGS.
.&_ WARNING
To reduce the risk of injury when an airbag
inflates, a lways wear safety belts prope rly.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of position in any
way, your risk of injury is much higher.
- You w ill also receive serio us 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
¢page 137.
.&_ WARNING
A child in a rearward-fac ing ch ild seat in
stalled on the front passenger seat will be
seriously inju red and can be killed if the
front airbag inflates - even w ith an Ad
van ced A irbag 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 instal led on the
front passenger seat, nobody can abso
lutely g uarantee that dep loyment is im
possible in all conceivable situations 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 great force and will
smash the child seat and child against
the backrest, center armrest, door, or roof.
- Always install rearward-facing ch ild re
straints 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
PASSENGER AIR BAG OFF light
does not come on and stay on, immed i
a tely insta ll the rear-facing child seat in a
rear seat ing pos ition and have the airbag
system inspected by your Audi dealer.
.&_ WARNING ,..___
If, in except iona l circumstances, you m ust
install a forward -facing child restraint on
the front passenger's seat:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacturer for use on a front seat
with a passenger front and s ide a irbag.
- Never p ut the forward-facing child re
straint up against or very near the instru
ment panel.
- Always move the passenger seat into its
rearmost pos ition in the seat's fore and
aft ad justment range, as far away from
the airbag as possible, before install ing
the forward-fac ing ch ild restra int. The
-
Page 147 of 294

backrest must be adjusted to an upright
posit ion.
- 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 signa l that it
is occupied by som eone who is heavier
than t he pe rson actually s itting on t he
sea t. T he presence of addition al obje cts
cou ld cause the passenger front airbag
to be t urned on when it sho uld be off, or
cou ld cause t he airbag to work in a way
that is different from the way it wou ld
have worked without the object on the
seat.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime w henever the ignition is switc hed
on.
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 150. Because 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 145
- 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
light in the instr ument cluster ¢
page 149.
-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
PASSENGER AIR BAG OFF li ght comes
on and stays on in the center of the instr u
ment panel ¢
page 150, fig. 144 and tells
you whe n the front Advanced Airbag on the

A WARNING
D amage to the fron t passenger se at can
p revent the front air bag from work ing
p roperly.
- Imp roper repai r or disassembly of the
front passenge r and dr iver seat will pre
vent the Advanced Airbag System from
functioning properly.

-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 min 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
Page 149 of 294

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 airbags 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
tan t information about safety and heed the
WARNINGS in this chapter .
Deployment of the Advanced A irbag 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 passenge r 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

A WARNING
To reduce the risk of injury w hen an airbag
in flates, always wear safety be lts p ro perly.
- If you are unrestra ined, leaning forward,
sitt ing s ideways or out of pos ition in any
way, your ris k of injury is m uch 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

More important things to know about
front airbags
Fi g. 14 3 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
v ide s upplementa l pro tect ion in a fron tal col
lis ion .
T he front airbags a re des igned to provide ad
di tional protection fo r the chest and fa ce 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 bli nk of an eye
wi th great force, things you have on your lap
or have placed on the seat cou ld become dan
gerous p rojecti les, and be pushed in to you if
t h e 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 .,,.

the vehicle. This dust is made up most ly o f 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 le ra ti on is high enough to deploy the air
bags.
Front airbags will not deploy:
- if the ignit io n 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 e lectronic 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 electron ic control unit
(the
PASSENGER AIR BAG OFF light
<> page 150 and how they wo rk comes on
and stays on).
.&_ WARNING
Sitting in the wrong posi tion can inc rease
the risk of serious injury in crashes .
- To reduce the r is k of i njury 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 whe
re
the airbags a re located .
- Occupants who are unbelted, out of posi
tion or too close to the airbag can be se
rio us ly injured by an airbag as it unfolds
with great force in the blink of an eye
