Child restraints on the front seat - some
important things to know
.. Be sure to read the important information
and heed the WARNINGS for important de­
tails about chi ldren and Advanced Airbags
~ page 171.
Even though your vehicle is equipped with an
Advanced Airbag System, make certain that
a ll chi ldren, especially those 12 years and
younger, always ride in the back seat properly restrained for their age and size. The airbag
on the passenger side makes the front seat a potentially dangerous place for a child to r ide .
The front seat is not the safest place fo r a
chi ld in a fo rward-facing chi ld seat. It can be a
very dange ro us p lace for an infant or a ch ild in
a rearward -facing seat.
The Advanced Airbag System i n your veh icle
has been cert ified to comp ly with the require­
men ts of United States Federa l Mo to r Veh icle
Safety Standard 208 as applicable at the time
your vehicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be t urned off ("sup­
p ressed") if a chi ld up to about one year of
age restrained in one of the rear -facing or for­
ward -facing infant restraints listed i n Federal
Motor Vehicle Safety Standard 208 with wh ich
the Advanced Airbag System in your vehicle
was certified has been installed o n the front
passenger seat. For a listing of the child re­
straints that were used to certify compliance
with the US Safety Standard ~
page 173.
The PASS ENG ER AIR BAG OFF light in the in­
strument panel te lls you when the front Ad­
vanced A irbag on the passenger side has been
turned off by the e lectronic control u nit.
Each t ime you sw itch on the ignit ion, the
PAS­
SENGER AIR BAG OFF
light w ill come on for a
few seconds and:
- will stay on if the front passenger seat is not
occupied,
- will stay on if the electrical capacitance
measured by the capacitive passenger de­
tection system for the front passenge r seat
A irbag sys tem 147
equa ls the combined capacitance of an in­
fant up to about one year of age and one of the rearwa rd-facing or forward-facing ch ild
restraints listed in Federal Motor Vehicle
Safety Standard 208 with which the Ad­
vanced Airbag System in your ve hicle was
cert ified. For a listing of the child restraints
that were used to certify your vehicle's com­ p lia nce w ith the U.S. Safety Standard
~page 173.
-w ill stay on if t he re is a small ch ild or child
restrai nt on the front passenge r seat,
- w ill go off if the front passenger seat is oc­
cupied by an adult as registered by the ca­
pacitive passenger det ection sys tem
~ page 15 7, Monitoring the Advanced Air­
bag System.
T he PASSENGER AIR BAG OFF lig ht comes on
when e lec trica l capacitan ce registe red on the
front passenger seat is eq ua l to or less than
the combined capacitance of a typical 1 year ­
o ld infant and one of the rearward-facing or
forward -facing chi ld restraints listed in Feder­
al Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your ve­
hicle was certified.
If the total e lectr ica l capacitance registered
on the front passenger seat is more than that
of a typical 1 year-o ld child but less than the
weight of a small adu lt, the front airbag on
the passenger side can deploy (the
PASSEN­
GER AIR BAG OFF
light does not come on).
If the
PASSENGER AIR BAG OFF light does
not come on, the front airbag on the passen­
ger side has not been turned off by the e lec­
tron ic contro l unit and ca n deploy if the con­
t rol unit senses an impact that mee ts the co n­
di tions s to red in its memo ry.
For example, th e airbag may deploy if:
-a small ch ild that is heav ier than a typical 1
year-old chi ld is on the front passenger seat
(regard less of whether the child is i n one of
the ch ild seats listed~
page 173), or
- a child who has outgrown child restraints is
on the front passenge r seat. .,,. •

148 Airbag sys tem
If the front passenger airbag is turned off , the
PASSENGER AIR BAG OFF light comes on in
the instrument cluster and stays on .
I f the front passenger airbag deploys, the
F ederal Standard requires the airbag to meet
the " low risk" deployment criteria to reduce
the r isk of in jury through interaction with the
a irbag. "Low ris k" deployment oc curs in tho se
c rashe s that take pl ace a t lower decele ra tions
as defined in the electronic control un it
c::> page 158, PASSENGER AIR BAG OFF light.
A lw ays r emember, a chi ld seat or infant carri­
er installed on the front seat may be s truck
and knocked out of position by the rap idly in ­
flati ng passenger's a irbag i n a frontal colli­
sion . The airbag could greatly reduce the ef­
fectiveness of t he ch ild restrai nt and even se­
r io usly in ju re the child during infla tion.
For this reason, and because the back seat is
the safest place for chi ldren - when p roperly
r estra ined a ccord ing to the ir age and size - we
strongly recommend t hat childre n always si t
in the back seat
c::> page 171, Child Safety .
& WARNING
-
A child in a rearward -facing child seat in ­
stalled on the front passenger seat will be
ser iously injured and can be killed if the
front airbag inflates - even with an Ad­
vanced Airbag System.
- The inflating a irbag will hit the child seat
or infant carrier w ith great force and w ill
smash the ch ild seat and child against
the bac krest , cen ter armres t, door or
roof.
- Always install rear-facing child seats on
the rear seat.
- If you must i nstall a rearward facing
child seat on the front passenge r seat
because of except iona l circumstances
and the
PASSENGER AIR BAG OFF ligh t
does not come on an d stay on, immedi­
a tely install the re ar-facin g chi ld seat in a
rear seating position and have the ai rbag
system inspected by your Aud i dealer. -
Forwa rd- facing child seats installed on
the front passenger 's seat may interfere
wit h the dep loyment of the a irbag and
cause serious persona l injury to the
child .
& WARNING
-If, in except ional circumstances, you m ust
i nstall a forward-facing child restraint on
the front passenge r's seat:
- Always make sur e the forward-facing
seat has been designe d and certified by
its m anufacture r for u se on a fron t se at
wit h a passenger fron t and s ide airba g.
- Never p ut t he fo rward -facing child re­
s tra int up agains t or ve ry near the instru­
men t pa nel.
- Always move the passenge r seat into it s
rearmost pos ition in the seat' s fore and
aft a djustmen t range, as fa r away from
the air bag as possible before installing
the forwar d-facing ch ild restra int . The
backrest must be ad justed to an upright
position.
- Make sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the
time whenever the ignit ion is switched
on .
& WARNING
-To reduce the risk of serious injury, make
sure that the
PASSENGER AIR BAG OFF
light w ill be display ed whe nev er a child re­
straint is insta lled on the front pa ssenger
se at and the ignition is sw itche d on .
- If the
PASSENGER AIR BAG OFF light
does no t stay on, per form the che cks de­
scribed
c::> page 15 7, Monitoring the Ad­
vanced Airbag System.
- Ta ke t he chi ld restraint off the fron t pas­
senger sea t and inst all it prope rly at one
of the rear seat positions i f the
PASSEN­
GER AIR BAG OFF
li ght does not stay on.
- Have the airbag system inspected by
your Aud i dea le r i mmediately.

152 Airbag sys te m
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
GER AIR BAG OFF
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 173),
-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 157.
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 145.
.&_ WARNING
A child in a rearward-fac ing ch ild 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
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
-

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 158. 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 153
- An elect ron ic contro l unit, with integrated
crash sensors fo r front and side impacts .
The control un it "decides" whether to f ire
the front a irbags 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 157.
-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¢

elec tro nic con trol un it.
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.

154 Airbag system
-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
PASSENGER AIR BAG OF F light
comes on and stays on to tell you when the
front Advanced Airbag System on the passen­ ger s ide has been turned off

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. 158 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 .,,.

156 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 while the
supp lemental airbag system is designed to re­
duce the likelihood of serious injuries, other
in juries, 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 lerat ion is high enough to deploy the air­
bags.
Front airbag s 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 158 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 147 .
.&_ 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 carrier 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 passe nger'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 th at it
is occupied by someone who is heavier
than the pe rson actually s itting on the
seat . The presence of an object co uld
cause the passenger front a irbag to be
turned on when it sho uld be
off, or co uld
cause the airbag to work in a way that is
different from the way it wou ld have
worked w ithout the object on the seat. A

A WARNING
The fine dust created when airbags deploy
can cause breathing prob lems fo r people
with a history of as thma or other breath­
ing cond itions.
- To reduce the risk of breath ing problems,
those wi th asthma o r other respiratory
conditions s hou ld get fresh air r ight
away by get ting o ut o f the veh icle or
open ing win dows or do ors.
- If you are in a collision in which airbags
deploy, was h your ha nds and fa ce with
mild soap and wate r be fore eating.
- Be ca reful not to get the dust in to your
eyes, o r into any c uts or sc ratches.
- If the resid ue should get into your eyes,
