about children and Advanced Airbags
¢page 291 .
Even though yo ur vehicle is equ ipped with an Ad­
vanced Airbag System, make certain that a ll chil­
dren, especially those 12 years and younger, al ­
ways ride in the back seat proper ly 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
safety seat. It can be a very dange rous place for
a n in fant or a child in a rearward-fac ing seat.
The Advanced Airbag System i n your veh icle has
been certified to comply with the requirements
of United States Federal Motor Vehicle Safety
Standa rd (FMVSS) 208, as well as Canada Motor
Ve hicle Safety Standa rd (CMVSS) 208 as applica ­
b le at the time your veh icle was man ufactu red.
According to requirements, the front Advanced
Airbag System on the passenger side has been
certified for "suppression" for infants of about 12 month old and younger and for "low risk de­
p loyment" for children aged 3 to 6 years o ld (as
defined in the standard).
The
PASSENGER AIR BAG O FF ~ ; light in the
headliner tells you when the front Advanced Air­
bag on the passenger side has been turned off by
the electronic control unit.
Each time yo u turn on the ignition, the
PAS SEN ­
GER AIR BAG OFF
for a few seconds and:
- PASSENGER AIR BAG OFF ~; will come on if
the front passenger seat is not occupied
- PASSENGER AIR BAG OFF the e lectrica l capacitance measured by the ca­
pacitive passenger detection system for the
front passenger seat equals the comb ined ca­
pacitance of an infant up to about one year of
age and one of the rearward-facing or forward ­
facing child restra ints listed in Federal Motor
Vehicle Safety Standard (FMVSS) 208 with
wh ich the Advanced Airbag System in your ve hi­
cle was certified. Fo r a listing of the child re ­
straints that were used to ce rtify you r vehicle 's

- PASSEN GER AIR BAG OFF ~; will come on if
there is a small chi ld or child restraint on the
front passenger seat
- PASSENGER AIR BAG ON @ will come on if the
front passenger seat is occupied by an adu lt as
registered by the capacitive passenger detec­
tion system
¢ page 281, Monitoring the Ad­
vanced Airbag System.
The PAS SEN GER AIR BAG OFF ~; light comes on
when e lectrica l capacitance registered on the
front passenger seat is equal to or less than the
combined capacitance of a typical 1 year-old in­
fant and one of the rearward-facing or forward­
facing child restra ints listed in Federal Motor Ve­
hicle Safety Standard (F MVSS) 208 with wh ich
t h e Advanced Airbag System in you r vehicle was
ce rtified.
If the total electr ical capacitance reg istered on
t h e front passenger seat is mo re than that of a
typ ica l 1 yea r-old ch ild but less than the weight
of a sm all adul t, the front airbag on the passen ­
ger side can deploy (the
PASSENGER AIR BAG
OFF
If the PASSENGER AIR BAG OFF~; light does
not come on, the fro nt airbag on the passenge r
side has not been t urned off by the e lectronic
contro l unit and can deploy if the contro l unit
senses an impact that meets the conditions stor ­
ed in its memory.
For example , th e ai rb ag ma y deplo y if:
- a small c hild that is heav ier than a typ ica l 1
year -o ld child is on the front passenger seat
(regard less of whethe r the child is in one of t he
child sa fe ty seats
listed ¢ page 293), or
- a child who has outgrown c hild rest raints is on
the front passenger seat .
If the front passenge r a irbag is tu rned off, the
PASSENGER AIR BAG OFF ~; light comes on in
t h e headliner a nd stays o n.
If the front passenger a irbag deploys, the Feder­
al Standard requ ires t he a irbag to meet the " low
r isk" deployment cr ite ria to redu ce the r isk of in­
j u ry throug h interact ion w it h t he airbag. "Low
risk" deployment occurs in t hose crashes that
take place at lower decelerations as defined in

-If you are unrestrained, leaning forward, sit­
t ing s ideways or out of pos ition in any way,
your risk of injury is much h igher.
- You will also receive serious injuries and
could even be killed if you are up aga inst the
airbag or too close to it when it inflates -
even with an Advanced
Airbag ¢ page 269.
A WARNING
A child in a rearward -facing child safety seat
installed on the front passenger seat w ill be
ser iously injured and can be killed if the front
airbag inflates - even w ith an Advanced Ai rbag
System.
- Although the Advanced A irbag System in
yo ur vehicle is designed to tu rn off the front
airbag when a rearward-facing child re­
straint has been insta lled on the front pas ­
senger seat, nobody can absolutely guaran­
tee that deployment is impossible in all con­
ceivable s ituations that may happen during
the useful life of your vehicle.
- The inflating a irbag w ill hit the child safety
seat or infant carrier with great force and
will smash the chi ld safety seat and child
against the backrest, center armrest, door,
o r roof .
- Always install rearward -facing ch ild re ­
straints on the rear seat .
- If you must install a rearward fac ing ch ild
safety seat on the front passenger seat be ­
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF ~; light does not
come on and s tay on, immed iate ly install
the rear-fac ing ch ild safety sea t in a rear
seat ing pos ition and have the airbag system
inspected by your authorized Audi dea ler.
A WARNING
If, in exceptional circumstances, you must in­
stall a forward-facing chi ld restraint on the
front passenger's seat :
- Always make sure the forward-facing seat
has been designed and cert ified by its man­
ufacturer for use on a front seat with a pas­
senger front and side a irbag.
276
- Never put the forward-facing child restraint
up against or very near the instrument pan­
el.
- Always move the front passenger seat to
the highest posit ion in the up and down ad­
justment range and move it back to the rearmost posit ion in the seat's fo re and aft
ad justment range, as far away from the a ir­
bag as poss ible, before installing the for­
ward-f acing chi ld restrain t.
- Always make sure that the safety be lt upper
anchorage is behind the ch ild rest raint and
not next to o r in fron t of the child rest raint
so that the safety be lt will be p roperly posi­
tioned.
- Always make sure that there is noth ing on
the front passenger seat tha t will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occup ied by a person when it is
not, or to signal that it is occupied by some­
one who is heavier than the person actually
sitt ing on the seat. The presence of addi­
tional objects could cause the passenger
front airbag to be turned on when it should
be off, or could cause the airbag to work in a
way that is differen t from the w ay it wou ld
have worked without the object on the seat .
- Ma ke sure that the
PASSENGER AIR BAG

time wheneve r the ignition is switched on .
Advanced Airbag System components
The front passenger seat in your vehicle has a lot
of very important parts of the Advanced Airbag
System in it. These pa rts include the capacitive
passenger detection system, wir ing, brackets,
and more . T he control unit monitors the system
o n the front passenger seat when the ignit ion is
switched on and turns the airbag indicato r light
o n when a malfunction in the one of the system
components is
detected ¢ page 281. Because
t h e fron t passenger sea t contains impo rtant
parts of the Advanced Ai rbag System , you must
take care to prevent it from being damaged .

More important things to know about front
airbags
F ig. 235 Inf lated fro nt a irbags

-.:,
~
Safety belts are important to help keep front
seat occupants in the proper seated position so
that airbags can unfold prope rly and provide sup·
p lemental pro tection in a frontal collision.
The front airbags are designed to provide add i­
tional protect ion for the chest and face of the
d river and the front seat passenger when:
- safety belts are worn properly
- the seats have been positioned so that the
oc -
cupant is properly seated as far as possible
from the airbag
- and the head restraints have been proper ly
ad-
justed
Because airbags inflate in the blink of an eye with
g reat fo rce, things you have on your lap or have
p laced on the seat cou ld become dangerous pro­
jectiles, and be pushed into you if the airbag in·
flates .
W hen an airbag deploys, fine dust is released.
This is normal and is not caused by a fire in the
veh icle. 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 while the sup ­
p lemental a irbag system is designed to reduce
the likelihood of ser ious injuries, other injuries,
for example swelling, bruising and minor abra -
Airbag system
sions, can also happen when airbags inflate . Air­
bags do not protect the arms or the lower parts
of the body. Front airbags supp lement the three ­
po int safety belts only in some frontal collisions
in which the vehicle dece leration is high enough
to dep loy the airbags .
Front airbags will not depl oy :
- if the ignition is switche d off when a crash oc-
curs
- in side co llisions
- in rear -end co llisions
- in rollovers
- when the crash decele ration measured by the
airbag system is less than the m inimum thresh­
old needed for airbag dep loyment as registe red
by the electronic con trol un it
The front passenger airbag also w ill not
deploy:
- when the fron t passenger seat is not occupied,
- when the e lectr ica l capacitance measured by
the capacit ive passenger detection system for
t he front passenge r seat ind icates that the pas­
senger side frontal airbag must be switched off
by the e lectronic control unit (the
PASSENGER
AIR BAG
OFF ~; light 9 page 281 comes on
and stays on).
A WARNING
Sitting in the wrong position can increase the
risk of ser ious injury in crashes.
- To reduce the r isk of injury when the a irbags
inflate, the driver and passengers must al·
ways sit in an upright posit ion, must not
lean aga inst or place any part of their body
too close to the area where the airbags are located.
- Occupants who are unbelted, out of posit ion
or too close to the airbag can be serio usly
inj ured by an airbag as it unfolds with g reat
for ce in the blink of an eye

Repair, care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing, remov ­
ing, servic ing or repa iring a part in an area of the
veh icle 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 w ill not be impaired and that discarded
components do not cause injury or pollute the
env ironment.
A WARNING
Improper care, serv icing and repai r proce­
dures can increase the r is k of personal injury
and death by preventing an airbag from de­
ploying when needed or dep loying an airbag
unexpectedly:
-
- Never cover, obstruct, or change the steer ­
ing wheel horn pad or airbag cover or the in­
strument pane l or modify them in any way.
284
- Never attach any objects such as cupholders
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness or strength of the material so
that the airbag cannot deploy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
- All work on the steering wheel, instrument
panel, front seats or e lectr ica l system ( in­
cluding the installation of a udio eq uipment,
cellular telephones and CB radios, etc.) m ust be performed by a qualified techn ician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we strong ly recommend that you see your au­
thorized Audi dealer or qualified workshop.
- Never modify the front b umper or parts of
the vehicle body.
- Always make sure that the side a irbag can
inflate without interference:
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
A udi.
- Never use additional seat c ushions that
cover the areas where the side airbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module mus t always be repaired immedi­
ate ly by an autho rized Aud i dealer .
- The a irbag sys tem can deploy on ly once. Af­
ter an airbag has been deployed, it m ust be
replaced with new replacement parts de­
signed and approved especia lly for your
Audi model version . Replacement of com­
plete airbag systems or airbag components
must be performed by qua lified workshops
only . Make sure that any airbag service ac­
tion is entered in your Audi Warranty

Airbag system
-the e lectronic control module and externa l side
impact sensors
- th e two side airbags located in the sides of the
front backrests
- two rear side airbags*
- the air bag wa rn in g light in the instrument clus-
te r.
The a irbag system is monitored electronically to
make certa in that it is functioning properly at all
times. Each time you turn on the ignition, the air­
bag system ind icator light will come on for a few
seconds (self diagnostics).
The s ide a irbag system supplements the safety
be lts and can help to reduce the risk of injury to
the driver's, front and rear* passenger's upper
torso on the side of the vehicle that is struck in a
side co llision . The airbag dep loys on ly in side im­
pacts and on ly when the vehicle acceleration reg ­
istered by the control unit is high enough. If this
rate is below the reference value programmed in­
to the control un it, the side airbags w ill not be
tr iggered, even though the car may be badly
damaged as a result of the collision. It is not pos­
sib le to define an ai rbag tr igger ing range that
w ill cover every possible angle of impact, s ince
t he circumstances will vary considerably between
one collision and another. Important factors in­
clude, for example, the nature (hard or soft) of
the impacting object, the angle of impact, vehicle
speed, etc.
c> page 287, Important safety in­
structions on the side airbag system.
Aside from their normal safety function, safety
be lts work to help keep the driver or front pas ­
senger in position in the event of a side collision
so that the side a irbags can provide protection.
The airbag system is
not a substitute for your
safety belt . Rather, it is part of the overa ll occu ­
pant restraint system in your vehicle. Always re­
member that the s ide airbag system can only
help to protect you if you are wearing your safety
belt and wearing it properly. This is another rea­
son why you should always wear you r safety
be lts, not just because the law requ ires you to do
soc> page 261, General information.
It is important to remember that while the sup­
plemental s ide a irbag system is designed to re-
286
duce the likelihood of serious injuries, other inju­
ries, for example, swelling, bruising, friction
burns and m inor abras ions can also be assoc iated
with deployed side airbags. Remember too, side
airbags will dep loy only once and only in certa in
kinds of accidents

your safety belts are always there to offer protec­
tion in those accidents in which airbags are not
supposed to deploy or when they have alr eady
deployed.
The side airbag system will not deploy:
-when the ignition is turned off
- in side co llisions whe n the accele ration meas-
ured by the sensor is too low
- in fro nt-end coll is ions
- in rear-end collisions
- in rollovers.
In some types of accidents t he front airbags, side
curtain airbags and side airbags may be triggered
together.
A WARNING
- Safety belts and the airbag system will only
provide protection when occupants are in
the proper seat ing position

triggering range that will cover every possible an­
g le of impact, s ince the circumstances will vary
considerably between one collision and another.
Important factors include, for example, the na­
ture (hard or soft) of the impacting object, the
angle of impact, vehicle speed, etc.

How side curtain airbags work .
Aside from their normal safety function, safety
be lts work to he lp keep the driver or front pas­
senger in pos it ion in the event of a collision so
that the side curtain airbags can p rovide protec­
tion .
The airbag system is not a substitute for your
safety belt . Rat he r, it is part of the overa ll occu­
pant restraint system in your veh icle . Always re­
member that the airbag system can only help to
p rotect yo u if you are wea ring your safety bel t
and wearing it properly . T his is another reason
why you should always wear your safety belts, not j ust because the law requires you to do so

It is important to remember that whi le the s ide
curtain ai rbag system is designed to he lp reduce
the likelihood of serious injuries, other inj uries,
for example, swelling, bruising, friction burns and minor abrasions can also be associated with
these airbags upon deployment . Remember too,
these airbags will deploy only once and only in

The side curtain airbag sy stem basically
consists of:
- The electronic contro l modu le and external s ide
impact senso rs
- The side curtain airbags above the w indows of
the outer seating positions with ejection miti­
gation feat ures
- The airbag ind icator light in the instrument
panel
The airbag system is monitored electronically to make certain it is funct ion ing properly at all
u times. Each time you turn on the ignit ion, the air-co

How side curtain airbags work
Side curtain airbags con work together with side
airbags to help reduce the risk of head and upper
torso injuries for occupants who are properly re­
strained.

Always replace ch ild restraints that were in­

a child restra int tha t is not visib le co uld cause
it to fail in another collision situation .
Advanced front airbag system and children
Your vehicle is equipped with an "Advanced Air­
bag System" in comp liance with United States
Federa l Motor Vehicle Safety Standard (FMVSS)
208, as well as Canada Motor Veh icle Safety
Standard (CMVSS) 208 as applicable at the t ime
your ve hicle was manufactured .
The Advanced Airbag system in your vehicle has
been certified to meet the "low-risk" requ ire­
ments for 3- and 6-year old children on the pas­
senger side and small adults on the driver side.
The low risk deployment crite ria are intended to
reduce t he r isk of injury thro ugh inte ract ion with
the airbag t hat can occur, for examp le, by being
too close to the steering whee l and instrument
panel when the airbag inflates . In addition, the
system has been certified to comply with the
"suppression" req uirements of the Safety Stand ­
ard, to turn off the front airbag for infants up to
~ 12 months who are restra ined on the front pas-...,
~ senger seat in child restraints that are listed i n
~ the Standard. 0 <( 0 00
Child s af ety
E ven thoug h your veh icle is equipped with an Ad ­
vanced Airbag system, all chi ldren, especially
those 12 years and younger, should a lways ride
in the back seat properly restrained for their age
and size . The airbag on the passenger side makes
the front seat a potentia lly dangerous p lace for a
ch ild to ride . Th e front seat is not the safest place
fo r a ch ild in a forward-fac ing ch ild safety seat.
It
can be a very dangerous place fo r an infant o r a
la rge r ch ild i n a rea rwa rd -facing seat.
T he veh icle 's Advanced A irbag System has a ca­
pacit ive passenger detection system in the front
passenge r seat cushion that can detect the p res ­
ence of a baby or a c hild in a child res tra int sys ­
tem on this seat .
T he capacitive passenger detection system reg is­
te rs the changes that result i n an elect rical field
whe n a child, a ch ild restraint, and a baby b la nket
are on t he fron t passenger seat. The change in
the measured capacitance due to the presence of a chi ld, a child restraint, and a baby blanket on
the front passenger seat is related to the child
restra int system resting on the seat. The meas­
ured capacitance of a child restra int system var­
ies depend ing on the type of system and specific
make and model.
The electrical capac itance of the various types,
makes, and models of child restraints specif ied
by the U .S . National Highway Traffic Safety Ad­
min istrat ion (NHTSA) in the relevant safety
standard are stored in the Advanced Airbag Sys­
tem contro l unit together with the capacitances
typ ica l of infants and a 1 -year old child. When a
c h ild restraint is used on the front passenger
seat with a typical 1 year -old infant, t he Ad ­
vanced Airbag System compares the capacitance
measured by the capacitive passenger detection
system with the data stored in the electronic con­
trol un it .
Child restraints and Advanced Airbags
Regardless of the ch ild restraint that you use,
make sure that it has been certified to meet Safe­
ty Standards and has been cert ified by its manu­
fact urer for use w ith an airbag . Always be s ure
