Child Safety
Important things to know
Introduction
The rear seat is generally the safest place in a collision.
The physical pr in ci ples o f wha t happens w hen yo ur vehicl e is in a crash
app ly a lso to children=>
page 199, "What happens to occupants not
wearing safety be lts?". But unlik e adu lts and teenagers, the ir
muscles and bones are not fully developed. In many respects c hildren
are at greate r risk of ser io us injury in cras hes than adults .
Because children 's bodies a re not f ully deve loped, they require
restraint systems especially designed fo r their size, weight, and body
st ruct ure. Many cou ntries and all states of t he Unite d States and
prov inces of Canada have laws req uiring the use of approved ch ild
restrain t sys tems for infan ts an d sm all ch ild ren .
I n a fronta l crash at a speed of 20 -35 mph (30-56 km/h) the forces
act ing o n a 13- pound (6 kg) infant w ill be more than 20 times the
we ight of the ch ild . This means the we ight of the child wo uld
suddenly be more than 260 po unds (120 kg). Unde r these conditions,
only a n app ropr iat e child restra int proper ly used can red uce the risk
of serious injury. Child restraints, like adult sa fety be lts, must be used
pro perl y to be effective. Use d imprope rly, they can i ncrease t he ris k
of serious injury in an accident.
C onsult the ch ild safety seat manufacturer's i nstr uctions to be s ure
t he seat is right for your child's size
=> page 234, "Importa nt safety
instructions for using ch ild safety seats" . P lease be sure to read and
heed all of the impo rtant informat io n and WAR NIN GS about child
safety, Advanced Airbags, and the insta llation of ch ild rest raints in
t his chapte r.
There is a lot you need to know about the Advanced Airbags in your
vehicle and how t hey wo rk when inf ants and childre n in child
restra ints are on the front passenger seat. Beca use of t he large

urge you to read the detailed information in th is owne r's man ua l
abou t airbags and t he Advanced A irbag System in your vehicle and the
very important information abo ut transporting c hildren on the front
p assenger se at. P lea se be sure to heed the WARNIN GS - they a re
extremely important for your safety and the safety of your passe n­
gers, especially infan ts and small ch il dre n.
& WARNING
• Accid ent statisti cs have shown that children are generally safer
in the rear seat area than in the front seating position. Always
re strain any child age 12 and under in the rear.
• All vehicle occupants and especially children must be
restrained properly when ever riding in a vehicle. An unre strained
or improperly restrained child could be injured by striking the
interior or by being ejected from the vehicle during a sudden
maneuver or impact. An unrestrained or improperly rest rained
child is also at greater risk of injury or death through contact with
an inflat ing airbag .
• A suitable child restraint properly installed and used at one of
the rear seating posi tions provides the highest degree of protec­
tion for infants and small children in most accident situations.
& WARNING
Children on the front seat of any car even with Advanced Airbags
can be seriously injured or even killed when an airbag inflates. A
c hild in a rearward -facing child safety seat ins talled on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflate s.
• The inflating airbag will hit the child safety seat or infant
c arrier with great force and will sma sh the child safety seat and
child against the backrest, center armrest, or door . •

and for the different models of the same kind of child restraint
offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of ch ild
restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typical infants and typical 1 year­
old child have been stored in the control unit of the Advanced Airbag
System. When a child restraint is being used on the front passenger
seat with a typical 1 year-old chi ld, the Advanced Airbag System
compares the weight meas ured by the weight sensing mat with the
information stored in the electronic control unit .
The electronic contro l unit a lso registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using the
safety belt as compared to the tension on the belt when it is used to
attach a child restraint to the seat . The sensor below the latch for the
safety belt for the front seat passenger measures the tension on the
belt. The input from this sensor is then used with the weight to
"decide", whether there is a child restraint with a typical 1 year-old
child on the front passenger seat and whether or not the airbag must
be turned off .•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, ma ke sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been ce rtified by its manufacturer for use with an
airbag . Always be sure that the child restraint is properly installed at
one of the rear seating positions. If in exceptional circumstances you
must use it on the front passenger seat, carefully read all of the infor­
mation on ch ild safety and Advanced Airbags and heed all of the
app licab le WARNINGS. Make certain that the child restra int is
correctly recognized by the weight-sensing mat inside the front
passenger seat, that the front passenger airbag is turned off and that
the airbag status is always correctly signaled by the

Controls and equip­ ment Safety first Vehicle operation
Many types and models of child restra
ints have been available over
t he years, new models are introduced reg ularly incorpo rating new
and improved designs and older models are taken out of product ion.
Chi ld restraints are not standardized. Child restraints of the same
type typ ically have d ifferent weights and sizes and differe nt 'foot­
prints,' the size and shape of the bottom of the child restraint that
sits on the seat, when they are installed on a vehicle seat . These
differences make it virtually impossib le to certify compliance with
t he requirements for advanced airbags with each and every chil d
restra int that has ever been sold in the past or will be sold over the
course of the useful life of your vehicle.
For this reason, the United States Nationa l Highway Traffic Safety
Administration has published a list of specific type, makes and
mode ls of child restra ints that must be used to cert ify compliance of
the Advanced Airbag System in yo ur vehicle with the suppression
requirements of Federal Motor Veh icle Safety Standard 208. These
child restraints are:

& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death.
• All vehicle occupants and especially children must always be
restrained properly whenever riding in a vehicle.
- An unrestrained or improperly restrained child can be injured or killed by being thrown against the inside of the
vehicle or by being ejected from it during a sudden maneuver or impact.
- An unrestrained or improperly restrained 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 pertaining to the instal­
lation and use of child safety seats and carefully follow the
instructions provided by the manufacturer of the seat you are
using.
• Never allow children under S7 inches (1.5 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 abdomen and neck areas during sudden braking maneuvers or
accidents.
• Never let more than one child occupy a child safety seat.
Controls and equip­ ment Safety first Vehicle operation
& WARNING
(continued)
• Never let babies or older children ride in a vehicle while sitting
on the lap of another 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 interior of the
vehicle and can also be struck by the passenger.
- The child and the passenger can also injure each another in
an accident.
• Never install rear-facing child safety seats or infant carriers on
the front passenger seat . A child will be seriously injured and can
be killed when the passenger airbag inflates - even with an
Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center armrest, door or roof.
• Always install rear-facing child safety seats or infant carriers
on the rear seat.
• Forward-facing child safety seats installed on the front
passenger's seat can interfere with the airbag when it inflates and
cause serious injury to the child. Always install forward-facing
child safety seats on the rear seat.
• If exceptional circumstances require the use of a forward­
facing child restraint on the front passenger's seat, the child's
safety and well -being require that the following special precau­
tions be taken:
- 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 side airbag.
- Always carefully follow the manufacturer's instructions
provided with the child safety seat or carrier.
Vehicle care Do-it-yourself service Technical data

-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).
Infants up to about one year (20 lbs. or 9 kg) are best protected in
special infant carriers and chi ld safety seats designed for t heir age
group. Many experts believe that infants and small childr en should
r ide only in spec ia l restra ints in w hich the child faces the back of the
vehicle. These infant seats support the baby's back, neck and head in
a crash=> fig. 222.
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 ch ild in a forward-facing child seat.
It is a very dangerous
place for an infant or a large r child in a rear ward-fac ing seat.
& WARNING
Not using a child safety seat, using the wrong child safety seat or
improperly installing a child restraint increases the risk of serious
personal injury and death in a crash.
• Never install rear-facing child safety seats or infant carriers on
the front passenger seat· even with an Advanced Airbag System.
A child will be seriously injured and can be killed when the
inflating airbag hits the child safety seat or infant carrier with
great force and smashes the child safety seat and child against the
backrest, center armrest, door or roof=>
page 208, "Child
restraints on the front seat -some important things to know".
• Always install rear-facing child safety seats or infant carriers
on the rear seat.
• Never install a rear-facing child rest raint in the forward-facing
direction. Such restraints are designed for the special needs of
infants and very small children and cannot protect them properly
if the seat is forward-facing.

The vehicle's safety belts alone will not fit most children until
they are at least 4 ft. 9 in. (57 inches/1.45 meters) tall and
weigh about 80 lbs. (36 kg). Booster seats raise these chil­
dren up so that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt can help
protect them in a crash.
- Do not use the convertible locking retractor when using
the vehicle's safety belt to restrain a child on a booster
seat.
- Always position the shoulder portion of the safety belt
midway over the child's shoulder. If you must transport an
older child in a booster seat on the front passenger seat,
you can use the safety belt height adjustment to help
adjust the shoulder portion prop erly.
- Always make sure that the shoulder portion of the safety
belt never rests against or across the child's neck.
