168 Airbag system
How knee airbags work
Applies to vehicles: with knee a irbags
The risk of injury to the leg area can be re­
duced by fully inflated knee airbags.
Fig. 165 Inflated airbags protecting in a frontal colli·
s io n
The knee airbag system has been designed so
that the a irbags for the driver and front pas­
senger deploy in certain but not all frontal
collisions.
If the front airbags deploy, the knee airbags
a lso deploy in frontal collisions when the de­
ployment threshold stored in the control unit
is met .
When the system deploys, the airbags fill
with a propellant gas, and inflate between the
lower part of the instrument panel and the
driver and the lower part of the instrument
panel and the front passenger~
fig. 162.
Although they are not a soft pillow, they can
"cush ion" the impact and in this way they can
help to reduce the risk of injury to the lower
extremities .
All of this takes place in the blink of an eye, so
fast that many people don't even realize that
the airbags have deployed . The airbags also
inflate with a great deal of force and it is im­
portant for occupant safety that nothing
should be in their way when they deploy.
Fully inflated airbags in combination with
properly worn safety belts slow down and lim­
it the occupant's forward movement and help
to reduce the risk of injury. Important safety instructions on the
knee airbag system
App
lies to vehicles : wi th knee airbags
Airbags are only supplemental restraints. Al­
ways wear safety belts correctly and ride in a
proper seating position.
There is a lot that you and your passengers
must know and do to help the safety belts and
airbags to provide supplemental protection.
A WARNING
-An inflating knee airbag can cause serious
injury. Wearing safety belts incorrectly and
improper seating positions increase the
risk of serious personal injury and death
whenever a vehicle is being used.
- The knee airbag system cannot protect
you properly if you are seated too close
to any of the airbag locations. When ad­
justing their seat positions, it is impor­
tant that both the driver and the front passenger keep their upper bodies and
knees at the following minimum safe
distances :
- at least 10 inches (25 cm) between the
chest and the steering wheel/instru­
ment panel.
- at least 4 inches (10 cm) between the knees and the lower part of the instru­
ment panel.
- The risk of personal injury increases if
you lean forward or to the side, or if the
seat is improperly positioned and you are
not wearing your safety belt . The risk in­
creases even more should the airbag de­
ploy.
- Always make sure that the knee airbag
can inflate without interference. Objects
between you and the airbag can increase
the risk of injury in an accident by inter­
fering with the way the airbag deploys or
by being pushed into you as the airbag
deploys.
- Never let anybody, especially children
or animals ride in the footwell in front

1 7 0 Airbag system
Always remember that the side airbag system
can only help to protect you if you are wearing
your safety belt and wear ing it properly. Th is
is another reason why you should a lways wear
your safety belts, not just because the law re­ qu ires you to do so
Q page 140, General
notes.
It is important to remember that while the
supplemental side a irbag system is designed
to reduce the like lihood of serious injur ies,
other inju ries, for example, swell ing, b ruising,
friction burns and minor abrasions can also be
associa ted with deployed side airbags. Re ­
member too, side airbags will deploy only
once and only in certain k inds of accidents -
your safety be lts are always there to offer pro­
tection .
Vehicle damage, repa ir costs or even the lack
of vehicle damage are not necessar ily an indi­
cation of over-sensitive or failed airbag activa­
tion. In some co llis ions, both front and side
a irbags may inflate. Remember too, that air­
bags will dep loy only once and only in certain
kinds of collisions -your safety belts are al­
ways there to offer protection in those acci ­
dents in wh ic h air bags are not supposed to
deploy or when they have already deployed .
The side airbag system will not deploy:
- when the ign ition is switched off
- in s id e collisions when the acce leration
measured by the sensor is too low
- in front-end col lisions
- in rear -end collisions
- in ro llovers.
In some types of acc idents the front airbags,
side curta in a irbags and side airbags may be
tr iggered together.
.&_ WARNING

- If the airbag indicator light Q page 19
comes when the vehicle is being used,
-
have the system inspected immediately
by your authorized A udi dealer. It is pos­
sible that the airbag will inflate when it
is not supposed to, or will not inflate
when it should .
How supplemental side airbags work
Side airbags deploy instantly and can help re­
duce the risk of upper torso injuries for occu­
pants who are properly restrained .
Fig. 167 In flated s ide a ir b ags o n left s ide of ve hicle ,

When the system is triggered, the a irbag is
filled with propellant gas and breaks through a seam in the seat su rface area marked "AIR ­
BAG ".
It expands between the side trim panel
and the passenger. In order to help provide

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

Child Safety
Important things to know
Introduction
The rear seat is generally the safest place in a
collision.
The physical principles of what happens when
your veh icle is in a crash app ly also to chi ldren
~ page 141, What happens to occupants not
wearing safety belts?.
But unlike adu lts and
teenagers, their muscles and bones are not
fu lly developed . In many respects children are
at greater risk of serious injury in crashes than
ad ults.
Because children's bod ies a re not fu lly deve l­
oped, they require restraint systems especial­ l y designed for their size, weight, and body
structure. Many co untries and all states of the
United States and provinces of Canada have
laws requ iring the use of approved ch ild re­
straint systems for infants and small children.
In a fronta l crash at a speed of 20 -35 mph
(30-56 km/h) the forces acting on a 13-pound
(6 kg) infa nt w ill be more than 20 t imes the
weight of the child . T his means the weight of
the child would suddenly be more than
260 pounds ( 120 kg). Under these conditions,
on ly an appropr ia t e chi ld restraint properly
used can reduce the risk of ser ious injury.
Ch ild restra ints, like adult safety belts, must
be used properly to be effective. Used improp ­
erly, they can increase the risk of ser ious in ­
jury in an accident.
Consult the ch ild safety seat manufacture r's
instr uctions in order to be sure the seat is
right fo r you r ch ild's size ~
page 179, Impor­
tant safety instructions for using child safety
seats.
Please be sure to read and heed all of
the impo rtant informat ion and WARNINGS
about ch ild safety, Advanced A irbags, and the
i nstallation of child rest raints in this chapter .
There is a lot you need to know about the Ad­
vanced A irbags in your vehicle and how they
wo rk when infants and children in child re-
Child Sa fet y 175
stra ints are on the front passenge r seat . Be­
ca use of the large amount of important infor­
mation, we cannot repeat it a ll here . We urge
you to read the detailed information in th is
owner's manua l about airbags and the Ad­
vanced Airbag System in your vehicle and the
very important information about transport­
ing children on the front passenge r seat .
Please be sure to heed the WARN INGS -they
are ex tremely importa nt for yo ur safety and
the safety o f you r passengers, especially in ­
f ants and small chi ldren .
.A, WARNING
-Accident statistics have shown that c hil­
dren a re generally safer in the rear seat
area than in the front seating position.
Always restrain any child age 12 and un­ der in the rea r.
- All vehicle occupants and especially chil­
dren must be restrai ned p roperly when­
eve r riding in a vehicle . An unr est rained
or improperly restrained chi ld could be
in ju red by str iking the interio r or by be­
ing ejected from the vehicle during a
sudden maneuve r or impac t. An un re ­
strained or improper ly restrai ned ch ild is
also at greater risk of injury o r death
through contact with an inflating airbag.
- A suitable chi ld restraint properly instal ­
led and used at one of the rear seat ing
positions p rov ides the highest degree of
protection for infants and small children
in most accident situations.
A WARNING
Ch ildren on the front seat of any car even
with Advanced Airbags ca n be ser iously in­
ju red or even kil led when an a irbag in­
fla tes. A child in a rearwar d-fac ing ch ild
safety seat installed on t he front passen ­
ger seat will be ser iously injure d and ca n
be killed i f the front airbag inflates .
- T he infla ting air bag will h it the ch ild
safety sea t or i nfan t carrie r wi th great
force and will smash the child safe ty seat
an d child against the bac krest , center
armrest, or door .

(D Tips
Always replace child restraints that were
installed in a vehicle during a crash. Dam­
age to a child restraint that is not visible
could cause it to fail in another collision
situation.
Advanced front airbag system and children
Your vehicle is equipped with a front "Ad­
vanced Airbag System" in compliance with United States Federal Motor Vehicle Safety
Standard (FMVSS) 208 as applicable at the
time your vehicle was manufactured.
The Advanced Airbag system in your vehicle
has been certified to meet the "low-risk" re­
quirements for 3- and 6-year old children on
the passenger side and small adults on the
driver side. The low risk deployment criteria
are intended to reduce the risk of injury
through interaction with the airbag that can
occur, for example, by being too close to the
steering wheel and instrument panel when
the airbag inflates. In addition, the system
has been certified to comply with the "sup­
pression" requirements of the Safety Stand­
ard, to turn off the front airbag for infants up
to 12 months who are restrained on the front passenger seat in child restraints that are list­
ed in the Standard.
Even though your vehicle is equipped with an
Advanced Airbag system, all children, espe­
cially those 12 years and younger, should al­
ways ride in the back seat properly restrained
for their age and size. The airbag on the pas­
senger 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 for­
ward-facing child safety seat. It can be a very
dangerous place for an infant or a larger child
in a rearward-facing seat.
The vehicle 's Advanced Airbag System has a
capacitive passenger detection system in the
Child Safety 177
front passenger seat cushion that can detect
the presence of a baby or a child in a child re­
straint system on this seat.
The capacitive passenger detection system
registers the changes that result in an electri­
cal field when a child, a child restraint, and a
baby blanket are on the front passenger seat .
The change in the measured capacitance due
to the presence of a child, a child restraint,
and a baby blanket on the front passenger
seat is related to the child restraint system resting on the seat . The measured capacitance
of a child restraint system varies depending
on the type of system and specific make and
model.
The electrical capacitance of the various
types, makes, and models of child restraints
specified by the U.S.National Highway Traffic
Safety Administration (NH TSA) in the relevant
safety standard are stored in the Advanced
Airbag System control unit together with the
capacitances typical of infants and a 1-year
old child. When a child restraint is used on the
front passenger seat with a typical
1 year-old
infant, the Advanced Airbag System compares
the capacitance measured by the capacitive passenger detection system with the data
stored in the electronic control unit.
Child restraints and Advanced front
airbag system
Regardless of the child restraint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu­
facturer for use with an airbag. Always be sure
that the child restraint is properly installed at
one of the rear seating positions. If in excep­
tional circumstances you must use it on the
front passenger seat, ca refully read all of the
information on child safety and Advanced Air­
bags and heed all of the applicable WARN­
INGS. Make certain that the chi ld and child re­
straint are correctly recognized by the capaci­
tive passenger detection system in the front passenger seat, that the front passenger air­
bag is turned off, and that the airbag status is ..,.

@ Tips
The child seats listed in categories A to C have been statically tested by Audi only for
the Advanced Airbag function.
Important safety instructions for using
child safety seats
Correct use of child safety sea ts substantially
reduces the risk of injury in an accident!
As the driver, you are responsible for the safe­
ty of everybody in the vehicle, especially chil­
dren:
~ Always use the right child safety seat for
each child and always use it properly
q page 181.
~ Always carefully follow the child safety seat
manufacturer's instructions on how to route
the safety belt properly through the child
safety seat.
~ When using the vehicle safety belt to install
a child safety seat, you must first activate
the convertible locking retractor on the
safety belt to prevent the child safety seat
from moving
r::!) page 186.
~ Push the child safety seat down with your
full weight to get the safety belt really tight
so that the seat cannot move forward or
sideways more than one inch (2.5 cm).
~ Secure unused safety belts on the rear seat
9page 181.
Always remember: Even though your vehicle is
equipped with an Advanced Airbag system, all
children , especially those 12 years and young­
er, should always ride in the back seat proper­
ly restrained for their age and size.
.&, WARNING ,~
Not using a child safety seat, using the
wrong child safety seat or improperly in­
stalling a child restraint increases the risk
of serious personal injury and death .
- All vehicle occupants and especially chil­
dren must always be restrained properly
whenever riding in a vehicle.
Child Safety 1 79
- An unrestrained or improperly restrain­
ed child can be injured or killed by be­
ing thrown against the inside of the ve­
hicle or by being ejected from it during
a sudden maneuver or impact.
- An unrestrained or improperly restrain­
ed child is at much greater risk of injury
or death by being struck by an inflating
airbag.
- Commercially available child safety seats are required to comply with U.S. Federal Motor Vehicle Safety Standard (FMVSS)
213 (in Canada CMVSS 213).
- When buying a child restraint, select
one that fits your child and the vehicle.
- Only use child restraint systems that
fully contact the flat portion of the
seat cushion . The child restraint must
not tip or lean to either side . Audi does
not recommend using child safety
seats that rest on legs or tube-like
frames. They do not provide adequate
contact with the seat.
-Always heed all legal requirements per­
taining to the installation and use of
child safety seats and carefully follow
the instructions provided by the manu­
facturer of the seat you are using.
- Never allow children under 57 inches
(1.45 meters) to wear a normal safety
belt. They must always be restrained by a
proper child restraint system. Otherwise,
they could sustain injuries to the abdo­
men and neck areas during sudden brak­
ing maneuvers or accidents.
- Never let more than one child occupy a
child safety seat.
- Never let babies or older children ride in a vehicle while sitting on the lap of an­
other passenger .
- Holding a child in your arms is never a
substitute for a child restraint system.
- The strongest person could not hold
the child with the forces that exist in
an accident. The child will strike the in­
terior of the vehicle and can also be
struck by the passenger. •

- Let the belt retractor wind up the safety be lt
webbing.
A WARNING
A child in a child safety seat installed with
the LATCH lower anchorages or w ith the
standard safety belt or a child in a booster
seat on the rear seat could play with un­
used rear seat safety belts and become en­
tangled. This could ca use the child serious
personal i nju ry and even death.
- Always secure un used rear seat safety
belts out of r each of chi ld ren in ch ild
sea ts su ch as by p rope rly routing them
around the head res traint of the seat
whe re the child restraint is installed.
- Never act ivate the sw itchab le locking re­

Child safety seats
Infant seats
Babies and infants up to about one year old
and 20 lbs. or
9 kg need special rearward-fac­
ing child restraints that support the back,
neck and head in a crash .
Fig. 171 Schemat ic overv iew: rearward -facing infant
seat, properly installed on the rear seat
~ When using the vehicle safety belt to install
a child safety seat, you must first activate
the convertible locki ng retractor on the
safety belt to preven t the child safe ty seat
from mov ing
Qpage 186 or install the seat
using the LATCH attachments .
~ Push the child safety seat down with you r
full weight to get the safety be lt really tight
so that the seat cannot move forward or
sideways more than one inch (2.5 cm).
~ Secure unused safety belts on the rear seat
Qpage 181.
Infants up to about one year (20 lbs. or 9 kg)
are best protected in special infant car riers
and child safety seats designed for their age
group. Many experts be lieve that infants and
small chi ld ren shou ld r ide o nly in special re­
str aints in wh ic h t he child faces the back of
the ve hicle. These infant sea ts suppo rt the ba­
by's back, neck and head in a crash ¢
fig. 171.
The airbag on the passenger side makes the
fron t seat a pote ntia lly dange ro us place for a
c hi ld to ride. The fron t se at is not t he safest
place for a child in a fo rward -facing child seat . ..,_

particularly the pelvis, of these children is not
fully developed, and they must not use the ve­ hicle safety belts without a suitable child re­
straint .
It is usually best to put these children in ap­ propriate booster seats. Be sure the booster
seat meets all applicable safety standards.
Booster seats raise the seating position of the
child and reposition both the lap and shoulder
parts of the safety belt so that they pass
across the child 's body in the right places. The
routing of the belt over the child's body is very
important for the child's protection, whether
or not a booster seat is used . Children age 12
and under must always ride in the rear seat.
Children who are at least 4
ft. 9 in. (57 in­
ches/1.45 meters) tall can generally use the
vehicle 's three point lap and shoulder belts .
Never use the lap belt portion of the vehicle's
safety belt alone to restrain any child, regard­ less of how big the child is. Always remember
that children do not have the pronounced pel­
vic structure required for the proper function
of lap belt portion of the vehicle's three point lap and shoulder belts. The child's safety ab­
solutely requires that a lap belt portion of the
safety belt be fastened snugly and as low as
possible around the pelvis. Never let the lap
belt portion of the safety belt pass over the
child's stomach or abdomen.
In a c rash, airbags must inflate within a blink
of an eye and with considerable force. In order
to do its job, the airbag needs room to inflate
so that it will be there to protect the occupant
as the occupant moves forward into the air­ bag.
A vehicle occupant who is out of position and
too close to the airbag gets in the way of an
inflating airbag. When an occupant is too
close, he or she will be struck violently and
will receive serious or possibly even fatal in­
jury.
In order for the airbag to offer protection, it is
important that all vehicle occupants, especial­
ly any children, who must be in the front seat
because of exceptional circumstances, be
Child Safety 185
properly restrained and as far away from the
airbag as possible. By keeping room between
the child 's body and the front of the passen­
ger compartment, the airbag can inflate com­
pletely and provide supplemental protection
in certain frontal collisions .
A WARNING
Not using a booster seat, using the boos­
ter seat improperly, incorrectly installing a
booster seat or using the vehicle safety
belt improperly increases the risk of seri­
ous personal injury and death in a collision
or other emergency situation. To help re­
duce the risk of serious personal injury
and/or death:
- The shoulder belt must lie as close to the
center of the child's collar bone as possi­
ble and must lie flat and snug on the up­
per body. It must never lie across the
throat or neck . The lap belt must lie
across the pelvis and never across the
stomach or abdomen . Make sure that the
belt lies flat and snug. Pull on the belt to
tighten if necessary .
- Failure to properly route safety belts
over a child's body will cause severe inju­
ries in an accident or other emergency
situation
¢ page 140.
- The rear side of the child safety seat
should be positioned as close as possible
to the backrest on the vehicle seat. Ad­
just or remove the rear seat head re­
straint if it is difficult to install the child
seat with the head restraint in place
¢ page 55. Install the head restraint
again immediately once the child seat is
removed . Driving without head restraints
or with head restraints that are not prop­
erly adjusted increases the risk of serious
or fatal neck injury dramatically.
- Children on the front seat of any car,
even with Advanced Airbags, can be seri­
ously injured or even killed when an air­ bag inflates.
- Never let a child stand or kneel on any
seat, for example the front seat.
