Child restraints on the front seat - some
important things to know
~ Be sure to read the impo rtant informat ion
and heed the WARNINGS for impo rtant de­
ta ils about ch ild ren and Advanced Airbags
Qpage 169.
Even though you r vehicle is equ ipped with an
Advanced Airbag Sys tem, ma ke certain that
all c hildren, especially those 12 years and
younger, a lways ride in the back sea t 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 ride.
The front seat is not the safest place for a
child in a forward-facing child seat. It can be a
ve ry dangerous 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 certified to comply with the require­
ments of United States Federa l Motor Ve hicle
Safety Standard 208 as applicable at the time
your ve hicle was manufactured.
The Standard requires the front a irbag on the
passenger side to be turned off ("sup ­
p ressed") if a c hild up to about one year of
age restra ined in one of the rear-facing o r fo r­
ward -facing infan t restra ints listed in Federal

The PASSENGER AIR BAG OFF light comes on
when e lec trica l capacitance registered on the
front passenger seat is eq ua l to or less tha n

forward-facing chi ld restraints listed in Fede r­
al Motor Vehicle Safety Standard 208 w ith
wh ich 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

Fo r exa mple, the airbag may depl 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 chi ld seats listed
page 171), or
- a ch ild who has outgrown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the
P ASS ENGER AIR B AG OFF light comes on in
the instrument cluster and stays on.
If the front passenger airbag deploys, the
Federal Standard requires the airbag to meet
the "low risk" deployment criter ia to reduce
the r isk of injury through interaction with the
airbag. "Low risk" deployment occurs in those
crashes that take place at lower decelerations
as defined in the electronic control unit
r::> page 159, PASSENGER AIR BAG OFF light.
Always remember, a chi ld seat or infant carri­
er insta lled on the front seat may be struck
and knocked out of position by the rapidly in­
flating passenger's airbag in a frontal colli­
sion. The airbag could greatly reduce the ef­
fectiveness of the child restraint and even se­
riously injure the child during inflat ion.
For this reason, and because the back seat is
the safest place for children - when properly
restrained according to their age and size - we
strongly recommend that children always sit
in the back seat
r::> page 169, Child Safety .
A 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 .
- T he inflating airbag will hit the child seat
or infant carrier with great force and wi ll
smash the child seat and child against
the backrest, center armrest, door or roof.
- Always install rear-facing child seats on
the rear seat.

- Forward-facing child seats installed on the front passenger's seat may interfere
with the dep loyment of the a irbag and
cause serious persona l injury to the
child.
A WARNING
If, in except iona l circumstances, you must
install a forward -facing child restraint on
the front passenger's seat:
- Always ma ke s ure 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 put the forward-facing child re­
straint up against or very 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 far away from
the airbag as possible before installing
the forward-fac ing ch ild restra int. The
backrest must be adjusted to an upright
position.
- Make sure that the

A WARNING ,.
If, in exceptional c ircumstances, you must
install a forward or rearward-fac ing child
restraint on the front passenge r's seat:
- Improper installation of child restraints
can reduce their effectiveness or even
prevent them from providing any protec­
t ion.
- An improperly installed child restraint
can interfere with the airbag as it de ­
ploys and serio usly injure or even kill the
child -even wi th an Advanced Airbag
System.
- Always carefully follow the manufactur­
er's instructions provided with the child
seat or car rier .
- Always m ake su re 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 Airbag
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 pe rson actually s itting on the
seat. The presence of additiona l objects
cou ld cause the passenger front airbag

Your vehicle is equipped with an "Advanced
Airbag System " in compliance with Un ited
States Federa l Motor Veh icle Safety Standard
(FMVSS) 208 as applicable at the time you r
vehicle was manufactured . The safety belts
for the seats have "pretensioners" that help to take slack out of the belt system. The pre­
ten sioners are also act ivated by the electronic
control unit for the airbag system.
T he front safety belts also have load lim iters
to help reduce the forces applied to the body
in a crash.

light does not come on).
For example, the a irbag may depl 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 chi ld seats listed

Alway s remember : Even though your 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, a lways wear safety belts prope rly.
- 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
fla tes - even with an Advanced Airbag

seriously injured and can be killed if the
front airbag inflates - even w ith an Ad­
vanced 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 installed on the
front passenge r seat, nobody can abso­
lutely guarantee that dep loyment is im­
possible in all conceivable s ituations that
may happen dur ing the usef ul life of your
veh icle.
- The infla ting airbag will h it the ch ild seat
or infant carrier with g reat 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.
- If you must insta ll a rearwa rd 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·
ately insta ll the rear-fac ing child seat in a
rea r seat ing pos ition and have the airbag
system inspected by you r Audi dealer .
A WARNING
If, in except iona l circumstances, you must
install a forward-facing child restraint on
the front passenge r's seat:
- Always ma ke sure the forward-facing
seat has been designed and cer tified by
its manufacture r for use on a front se at
with a passenger fron t and s ide a irbag .
- Never put the fo rward-facing child re­
straint up against or ve ry near the instru­
ment panel.
- Always move the passenge r seat into its
rea rmost 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 ad justed to an upright

Advanced Airbag System components
The front passenger seat in your vehicle has a
l o t of very important pa rts of the Advanced
A irbag System in it. These parts incl ude the
capacitive passenger detect ion sys tem, wir­
ing, brac kets, 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 indicator light on w hen a
malfunction i n the one of the system compo­
n ents is detected
c::;, page 159 . Because the
front passenge r seat contains important pa rts
of the Advanced Airbag System, you must
take ca re to pr even t it from be ing damaged.
Damage 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 senso rs in the front o f the veh icle that
measure ve hicle acceleration/dece leration
to provide information to the Advanced Air­ bag System abo ut the severity of the crash .
- An electronic co ntro l unit, with i ntegrated
c rash sensors for f ront and side impacts.
The cont ro l unit "decides" whether to fire t
he front a irbags based on the in format ion
received from the crash sensors. The contro l
un it also "decides" whether the sa fety belt
pretens ioners sho uld be activated.
- An Advanced Airbag with gas generator fo r
the dr iver inside the steering wheel hub.
- An Advanced Airbag with gas gene rator in­
side the inst rument panel for the front pas­
senger.
- A capacit ive passenger detection system un­
derneath the front passenger seat cover.
This system measures the electrical capac i­
tance of the person in the seat. The informa­
tion registered is se nt cont inuous ly to the
elect ronic 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 t he i nstr ument cluster

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 safety be lts
with pretensioners and load limiters and the
adjustable head restra ints* 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 abo ut safety and heed the
WARNINGS in this c hapter .
Dep loyment of the Advanced Airbag System
and the activat ion of the safety be lt preten­
sioners depend on the dece lerat ion meas ured
by the c rash senso rs and regis tered by the

The front airbags are des igned 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 posi tioned 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 ad justed .

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 ve hicle . 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

duce the like lihood of serious injur ies, other
injur ies, for examp le swelling, bruising and
minor abrasions, can also happen when air-

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

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

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

A WARNING
r---------
O b j e cts between you and the airbag will
increase the risk 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 if the a irbags inflate.
- Never p lace or attach accesso ries o r oth­
