Child restraints on the front seat - some
important things to know
• Be sure to read the impo rtant in forma tion
and heed the WARNINGS for important de­
ta ils about ch ildren and Advanced Airbags
Q page 166.
Even though yo ur vehicle is equipped with an
Advanced Airbag System, make certain that
all children, especially those 12 years and
younger, a lways ride in the back seat properly
restra ined 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-faci ng chi ld sea t.
It can be a
ve ry dangerous p lace for an infant or a c hild in
a rearward -facing seat.
The Advanced Airbag System i n your veh icle
has been certified to comply with the require­
men ts of Uni ted States Federa l Mo to r Veh icle
Safety Standard 208 as applicable at the time
your ve hicle was manufact ured.
The Standa rd requires the fron t air bag on t he
passenger side to be turned off ("sup­
p ressed") if a c hild up to about one yea r of
age restrained in one of the rear-facing or for­
ward-facing infant restra ints listed in Federal
Motor Vehicle Safety Standard 208 with which
the Advanced A irbag System in your vehicle
was certified has been installed on the front passenger seat. For a listing of the child re­
straints that we re used to certify compliance
with the US Safety Sta ndard
Q page 168.
The PASSENGER AIR BAG OFF light in the in­
strument panel te lls you when the front Ad­
vanced A irbag on t he passenger side has been
turned off by t he e lectronic control unit.
Each t ime you sw itch on the ignit ion, the
PAS­
SENGER AIR BAG OFF
li ght w ill come on for a
few seconds a nd:
- will stay on if the front passenger seat is not
occupied,
- will stay on if there is a small child or child
rest raint on the front passenger seat, -
w ill go off i f the front passenge r seat is oc ­
cupied by an adult as registere d by the
weight -sensing mat
<:!) page 153, Monitor­
ing the Advanced Airbag System.
T he PASSENGER AIR BAG OFF light comes on
when the contro l unit detects a tota l weight
on the front passenger seat that req uires the
front a irbag to be turned off.
If the total weight on the front passenge r
seat is more than that of a typica l 1 year -old
c hi ld b ut less than the we ight of a small
adult, the front airbag on the passenger side
can deploy (the
PASSENGER AIR BAG OFF
li ght does not come on). If the PASSENGER
AIR BAG OFF
light does not come on , the
front a irbag on the passenger side has not
bee n tur ned off by the elec tronic con trol unit
and can deploy if the control uni t se nses an
impact that meets the con ditions stored i n its
memo ry .
For exampl e, the airbag may deploy if:
- a small ch ild that is heav ie r th an a typical 1
year-old ch ild is on the front passenger seat
( r egard less of whethe r the child is in one of
t he child seats listed
Q page 168), or
- a child who has outgrown ch ild restraints is
on t he front passenge r seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instr ume nt cluster and stays on.
The front airbag on the passenger side may
not deploy (the PASSENGER AIR BAG OFF
li gh t does not illum inate and stay lit) even if a
small ad ult o r teenager, or a passenger who is
not sitt ing up rig ht w ith their back against a
non- re cli ned ba ck res t w it h thei r feet on the
vehicle f loor in front of the sea t is on the front
passenge r seat
c::> page 125, Proper sea ting
position for the driver.
If t he front passenger a irbag dep loys, the
F ede ral Standard req uires the airbag to meet
t h e "low risk" dep loyment criteria to red uce
the risk of injury t hro ugh interactio n wit h the
airbag. "Low risk" dep loyment occ urs in those
crashes that take place at lower dece lerat ions ..,_

as defined in the electronic control unit
¢ page 153, PASSENGER AIR BAG OFF light .
Always remember, a chi ld seat or infant ca rri­
e r i nsta 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 red uce the ef­
fectiveness of the child restraint and even se­ riously injure the child during inflat ion.
F or this reason, and because the back seat is
the safest p lace for children -when properly
restra ined accord ing to their age and si ze -we
strongly recommend that children always sit
in the back seat
¢ page 166, 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 .
- The inflating a irbag w ill hit the child seat
or infant carrier w ith great force and w ill
smash the ch ild seat and child against
the backrest, center armrest, door or
roof .
- Always install rear -facing child seats on
the rear seat .
- If you mus t install a rearward facing
child seat on the front passenge r seat
because of exceptiona l circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the rear-facing chi ld seat in a
rear seating position and have the airbag
system inspected by your Aud i deale r.
- Forward-fac ing ch ild seats installed on
the front passenger's seat may interfere
with the deployment of the airbag and cause serious pe rsonal injury to the
child.
A WARNING
If, in exceptional c ircumstances, you mus t
install a forwa rd-facing child restra int on
the front passenger's seat:
A irbag system 145
-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 put the forward-facing child re­
straint up against or very near the instru­ ment panel.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as fa r away from
the airbag as possible before installing
the forward-fa cing ch ild restra int. The
backrest mu st be ad justed to an upright
posi tion.
- Ma ke sure that the
PASSENGER AIR BAG
OFF
li ght comes on and stays on all the
time wheneve r the ignit ion is swi tched
on.
A WARNING
To reduce the risk of serious injury, make
sure that the
PASSENGER AIR BAG OFF
light will be displayed whenever a child re­
straint is installed on the front passenger
seat and the ignition is sw itched on.
- If the
PASSENGER AIR BAG OFF light
does not stay on, perform the checks de­
scribed
¢ page 153, Monitoring the Ad­
vanced Airbag System .
-Take t he chi ld restraint off the front pas­
senger seat and install it properly at one
of the rear seat positions if the
PASSEN­
GER AIR BAG OFF
light does not stay on.
- Have the airbag system inspected by
your Aud i dea le r i mmediately.
- Always carefully follow instr uctions from
child restraint manufacture rs when in­
stalling c hild restra ints.
A WARNING
If, in e xcept io na l circumstances, you must
ins tall a forward o r rearwa rd-facing child
restra int on the front passenger's se at:
- Imp roper install ation of ch ild restrai nts
can reduce their effec tiveness o r even
preven t them from providing any protec­
tion. •
•

146 Airbag system
-An improperly installed child restraint
can interfere with the airbag as it de ­
ploys and seriously injure or even kill the
child -even with an Advanced Airbag
System .
- Always carefully follow the manufactur­
er's instructions provided with the child
seat or carrier .
- Never place additional items on the seat
that can increase the total weight regis­ tered by the weight-sensing mat and can
cause injury in a crash .
Front airbags
Description of front airbags
The airbag system con provide supplemental
protect ion to properly restrained front seat
occupants.
Fig. 145 Location of dr iver airbag: in stee ring wheel
Fig. 146 Locat ion of front passenger's airbag: in the in­
s trument panel
Your vehicle is equipped with an "Advanced
A irbag System" in compliance with United
States Federal Motor Vehicle Safety Standard
(FMVSS) 208 as applicable at the time you r
vehicle was manufactured. The system senses
the position of the front seats and controls
front airbag inflation with a valve, depending on
the distance between the respective seat
and the steering wheel or instrument panel.
The safety belts for the seats have "preten­ sioners" that help to take slack out of the belt
system. The pretensioners are also activated by the electronic control unit for the airbag
system.
The front safety belts also have load limiters
to help reduce the forces applied to the body in a crash .
The airbag for the driver is in the steering
wheel hub
c::;, fig. 145 and the airbag for the
front passenge r is in the instrument panel
c::;, fig . 146 . The general location of the airbags
is marked "AIRBAG".
There is a lot you need to know about the air­
bags in your vehicle. We urge you to read the
detailed information about airbags, safety
belts and child safety in this and the other
chapters that make up the owner's literature .
Please be sure to heed the WARNINGS -they
are extremely important for your safety and
the safety of you r passengers, especially in­
fants and small children.
A WARNING
Never rely on airbags alone for protection.
- Even when they deploy, airbags provide
only supplementa l protection .
-Airbag work most effectively when used
with properly worn safety belts.
- Therefore, always wear your safety belts
and make sure that everybody in your ve ­
hicle is properly restrained .
A WARNING
A person on the front passenger seat , es­
pecially infants and sma ll children, will re­
ceive serious injuries and can even be kil­
led by being too close to the airbag when
it inflates .
- Although the Advanced Airbag System in
your vehicle is designed to turn off the
front passenger airbag if an infant or a
small child is on the front passenger
seat, nobody can absolutely guarantee ..,.

148 Airbag sys tem
an impact that meets the conditions stored in
its memory .
I f the tota l weight on the front passenger
seat is more than that of a typical 1 year-o ld,
but less than the weight of a small adu lt, the
front airbag on the passenger side may deploy (the
PASSENGER AIR BAG OFF light does not
come on).
For e xample , 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 p assenger seat
(regardless of whe ther the child is in one of
the chi ld seats listed
¢ page 168),
- a ch ild who h as o utg rown child rest raints is
on the front passenger seat.
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF l ight in the cente r
of the inst rument panel w ill come on and stay
on.
The front a irbag on the passeng er side may
not dep loy (the PAS SENGER AIR BAG OFF
light does not ill umin ate and stay lit) if:
- a small adult or teenager is o n the front pas­
senger seat
- a passenger who is not sitt ing upright wit h
their back against a non-reclined backrest
with their feet on the veh icle floo r in front
of the seat is on the front passenge r seat.
If the front passenger airbag deploys, the Federal Standard requires the a irbag to meet
the " low risk" deployment criteria to help re­
d uce the risk of inj ury through inter action
with the airbag. " Low r isk" deployment occurs
in those crashes that take place at lower de­
celerations as defined in the e lectronic control
un it
¢ page 153.
Alwa ys remember : Even though yo ur vehicle
is equipped with Advanced Airbags, the safest
p lace for children is properly restrained on the
bac k 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.
A WARNING
To reduce the risk of injury when an a irbag
i nflates, always wear safety be lts properly.
- 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 h igher.
- You will a lso receive serious injuries and
could even be killed if you are up aga inst
the airbag or too close to it when it in­
flates -even w ith an Advanced A irbag
¢ page 142.
A WARNING
A child in a rearward-fac ing ch ild seat in­
stalled on the front pa ssenger se at will be
se riously in jured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System.
- Al tho ugh the Advan ced Airbag Sys tem in
your veh icle is designe d to turn off the
front airbag when a rearward-facing
child restraint has been installed 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 car rier with g reat force and will
smash the child seat and child against
the backrest, center armrest, door, or
roof.
- Always inst all rearward-fa cing ch ild re­
s traints on the rear seat.
- I f you must ins tall a rearwa rd fa cing
child sea t on the fron t passenger seat
because of exceptional circumstan ces
an d the
PASSENGER AIR BAG OFF light
does not come on and stay on, imme di­
ately insta ll the rear-facing 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
i nstall a forward-facing child restraint on
the front passenge r's seat:

_& WARNING
Damage to the front passenger seat can
prevent the front airbag from working
properly.
- Improper repair or disassembly of the
front passenger and driver seat wi ll pre­
vent the Advanced A irbag System from
functioning properly.
- Repairs to the front passenger seat must
be performed by q ualified and properly
trained workshop personnel.
- Never remove the front passenger or
dr iver seat from the veh icle.
- 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 place them on the seat . If the weight­
sensing mat in the passenger seat is
punctured it cannot work properly.
- Never carry things on your lap or carry
objects on the passenger seat. Such
items can increase the weight registered
by the weight-se nsing mat and send the
wrong info rmation to the airbag control
unit.
- Never store items under the front pas­ senger seat. Parts of the Advanced Ai r­
bag System under the passenge r seat
c ou ld be damaged, prevent ing them and
the a irbag sys tem from working proper ­
ly .
- N ever place sea t covers or replacement
upholstery that have not been specifical­
ly approved by A udi on the fron t seats.
- Seat covers can preven t th e Advanced
Airbag System from recognizing child re ­
st raints or occupants on the front pas­
senger seat and prevent the side airbag
in the seat backrest from deploy ing prop­
er ly.
- Never use cushions, pillows, blankets or
similar items on the front passenger seat. The add itiona l padd ing will prevent
the weight-sensing mat in the seat from
accu rately reg iste ring the c hild restra int
-
or person on the seat and prevent the
Advanced Airbag System from function­
ing p roperly.
- If you must use a child restraint on the
front passenger seat and the child re­
straint manufacturer's instructions re­
qu ire the use of a towel, foam cushion or
something e lse to prope rly pos ition the
child restraint, make certain t hat the
PASSENGER AIR BAG OFF lig ht comes
on and stays on whenever the ch ild re­
straint is installed on the front passen ­
ge r seat .
- If the PASSENGER AIR BAG OFF light
does not come on and stay on, immedi ­
ately insta ll child restraint in a rear seat­
ing position and have the ai rbag system
inspected by your Audi dea ler.
How the Advanced Airbag System
components work together
T he front Advanced Airbag System and the
s ide a irbags supp lem ent the p rotection of­
fered by the front three-po int safety belts
with pre tensione rs and load lim iters and the
adjustable head res train ts to help redu ce the
risk of in jury in a wide ra nge of accident and
crash situations . Be s ure to read the impor­
tant information about safety and heed the
WARNINGS in th is chapter.
Deployment of the Adv a need Airbag System
and t he activation of the safety belt preten ­
s ioners depend on the deceleration measured
by the crash sensors and registered by the
electron ic co ntrol unit. The amount of infla­
t ion of t he front airbags can a lso be adapted
to the front seat pos ition, depending on the
distance between the respective front seat
and t he steer ing w heel or instrument panel as
regis tered by sensors in the seats. C rash se ­
verity depends on speed and dece leration as
well as the mass and st iffness of t he vehicle
or object involved in the crash .
On t he passenger side, rega rdless of sa fe ty
belt use, the airbag w ill be turned off if the
weight on the passenger seat is less than the ..,.

amount prog rammed in the e lec tronic control
u nit. The front airbag on the passe nger side
will also be turned off if one of the ch ild seats
that has been certified u nder Fede ral Motor
Vehicle Safety Standard 208 has been recog­ n ized o n the seat. The
PASS ENGER AIR BAG
OFF li gh t comes on and stays on to tell you
when the front Advanced A irbag on the pas­
se nger side has been tu rned off
Q page 144,
Child restraints on the front seat -some im­
portant things to know.
A WARNING
To reduce the risk of injury when an airbag
inf lates, a lways wear safety belts properly.
- If you are unrestrained, lean ing fo rward,
sitting sideways or out of position in any
way , yo ur risk of inj ury is much higher.
- You wi ll 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

More important things to know about
front airbags
F ig. 14 7 Inflated front a irbags
Safety belts are important to help keep front
seat occupants in the proper seated pos ition
so that airbags can unfo ld properly and pro­
v ide supplemental protection in a fronta l co l­
lision .
The front a irbags are designed to provide ad­
d itiona l protection for the chest and face of
the dr iver and the front seat passenger when :
- safety be lts are worn properly,
A irba g sy stem 151
- the seats have been positioned so that the
occ upant is properly seated as far as possi­
ble from the airbag,
- and the head restrai nts have been properly
adjusted .
Beca use ai rb ags infl ate i n t he bli nk o f an eye
wi th great fo rce, th ings you have on your lap
or have p laced on the seat co uld become dan­
gerous p ro jecti les, and be p ushed into you if
the a irbag inflates.
When an airbag deploys, fine dust is re leased .
T his is norma l and is not ca used 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 remember that wh ile the
s u pplementa l airbag system is designed to re­
duce the like lihood of serious injur ies , other
injuries, for example swelling, bru is ing and
minor abrasions, can also happen when air­
bags i nflate . A irbags do not protect the arms
or the lower parts of the body. Front a irbags
suppleme nt the th ree-point safety be lts only
i n some fronta l colli sions in which the vehicle
deceler ation is high e nough to deploy the air­
bags .
Front airbags will not deploy :
-if the ignition is sw itched off when a c rash
o ccur s,
- in side co llisions,
- in rear-end coll is ions,
- in rollovers,
- when the crash deceleration measu red by
the airbag system is less than the minimum
threshold needed for a irbag deployment as
reg istered by the electro nic contro l unit .
The front passenger airbag also will not
deploy:
-when the front passenger seat is not occu­
pied,
- when the weight on the front passenger seat as sensed by the Advanced Airbag Sys­
tem ind icates that the front a irbag on the
passenger side has to be turned off by the
II>

152 Airbag sys te m
electronic contro l uni t (the PAS SENGER AIR
BAG OFF
light comes on and stays on) .
A WARNING
Sitting in the wrong position can increase
the risk of serious injury in crashes.
- To reduce the risk 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 the ir body too close to the area where
the a irbags are located .
- Occupants who are 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
<=?page 144.
A WARNING
-
A child in a rearward -facing child sea t in­
stalled on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates -even with an Ad­
vanced Airbag System.
-The inflating ai rbag will hit the child seat
or infant carrier with great force and will
smash the ch ild seat and child against
the backrest , center armrest, door or
roof .
- Always install rear-facing child seats on
the rear seat.
- If you must install a rearward facing child seat on the front passenger seat
because of except iona l circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately i nstall the rea r-facing chi ld seat in a
rear seating position and have the ai rbag
system inspected by your Au di dealer.
A WARNING
Objects be tween you and the a irbag will
increase the risk of in jury in a c rash by in ­
terfering with the way the airbag unfolds
or by being pushed into yo u as the a irbag
inf lates. -
Never hold things in you r hands o r on
your lap when the veh icle is in use.
- Never transpo rt items on or in t he a rea
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 dangero us projec ­
tiles that can cause ser ious personal in­
jury if the a irbags inf late .
- Never p lace or attach accesso ries o r oth ­
er objects (such as cup hold ers, te le­
phone b ra ck ets, large, heavy or bulky ob­
jects) on the doors, ove r o r ne ar the are a
marked "AIRBAG" on the s teer ing whee l,
instr ument panel, sea t bac krests o r be ­
tween those areas and yourself. These
objects could ca use in jury in a crash, es­
pecially when the airbags inflate.
- Never recline the front passenger 's seat
to transport objects. Items can a lso
move into the area of the s ide airbag or
the front a irbag during braki ng or in a
sudden maneuve r. Objects near the air­
bags can become projectiles and cause
in jur y, partic ularly when the seat is re­
clined.
A WARNING
The fine dus t create d when air bags deploy
c a n cause breathing p rob lems fo r people
wi th a history of as thma or other breath ­
i ng cond itions.
- T o reduce the risk of breath ing pro blems,
those with asthma or other respiratory
conditions s hou ld get fresh air right
away by getting o ut o f the veh icle or
open ing windows or doors .
- If you are in a collision in which airbags
deploy, wash your hands and face with
mild soap and water before eating.
- Be careful not to get the dust into your
eyes, or into any c uts or scratches.
- If the res id ue should get into your eyes,
f lush them w ith water.

Monitoring the
Advanced Airbag
System
I ( USA models) /!{ (Canada models )
Airbag monitoring indicator light
Two separate indicators monitor the function
of the Advanced Airbag System: the airbag
monitoring indicator light and the
PASSEN­
GER AIR BAG
OFF light.
The Advanced Airbag System (including the
electronic control unit, sensor circuits and sys­
tem wiring) is monitored continuously to
make sure that it is functioning properly
whenever the ignit ion is on. Each time you
switch on the ignition, the airbag monitoring
indicator light
m (USA mode ls)/ m (Canada
models) will come on for a few seconds (self
diagnostics).
The system must be inspected when the indicator light
(I (USA models);Ei
(Canada models):
-does not come on when the ignition is
switched on ,
- does not go out a few seconds after you
have switched on the ignition, or
- comes on while driving.
If an airbag system malfun ction is detected,
the indicator light will first start flashing to
catch the driver's attention and then stay on
continuously to serve as a constant reminder
to have the system inspected immediately.
If a mal function occurs that turns the front
airbag on the passenger side
off, the PASSEN­
GER AIR BAG
OFF light will come on and stay
on whenever the ignition is on.
A WARNING
An airbag system that is not funct ioning
properly cannot provide supplemental pro­
tection in a frontal crash.
- If the airbag indicator light comes on, it
means that there may be something
wrong with the Advanced Airbag System .
It is possible that the airbag will inflate
