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.

Infants up to about one year (20 lbs . or 9 kg)
are best protected in special infan t carriers
and child safety seats designed for their age
group . Many experts believe that infants and
small children should ride only in spec ial re­
straints in which the ch ild faces the back of
the vehicle. These infant seats support the ba­
by's back, neck and head in a crash

A WARNING
Not using a child safety seat, using t he
wrong child safety seat or improperly in ­
stall ing a ch ild restraint increases the risk
of ser ious personal injury and death in a
crash.
- Never install rearwa rd-facing child safety
seats or infant ca rr ie rs on the front pas­
senger seat -even with an Advanced Air ­
bag Sys tem. A ch ild will be ser iously in­
jured and ca n be killed when the inflat ­
ing airbag hits the child safety seat or in­
fant carrier with great force and smashes the child safety seat and child against
the backrest, center armrest, door or
roof ¢

Convertible child safety seats
Properly used convertible child safety seats
can help protect toddlers and children over
age one who weigh between
20 and 40 lbs. (9
and 18 kg) in a crash.

A toddler or child is usually too large for an in­
fant restraint if it is more than one year old
and weighs more than 20 lbs. (9 kg) . Toddlers
and children who are older than one
year up to about 4 years old and weigh more
than 20 lbs. (9 kg) up to 40 lbs. (18 kg) must
always be properly restrained in a child safety
seat certified for their size and weight
c:> fig . 163 and c:> fig . 164 .
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 safe­
ty seat . It is a very dangerous place for an in­
fant or a larger child in a rearward-facing seat.
_&. 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 in a
collision or other emergency situation.
- 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 . A child in a rearward-facing
child safety seat installed on the front passenger seat will be seriously injured
and can be killed if the front airbag in­
flates -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 rearward-facing child safe­
ty seats on the rear seat.
- If you must install a rearward facing
child safety seat on the front passenger
seat because of exceptional circumstan­
ces and the
PASSENGER AIR BAG OFF
light does not come on and stay on, im­
mediately install the rearward-facing
child safety seat in a rear seating posi­
tion and have the airbag system inspect­
ed by your authorized Audi dealer .
- The rear side of the child safety seat
should be positioned as close as possible ..,.

174 Child Saf ety
• Secure unused safety belts on the rear seat
9 page 170 .
Children up to about 40 lbs. (18 kg) are best
p rotected in child safety seats designed for
their age and weight . Experts say that the
skeleta l structure, particular ly the pelvis, of
these children is not fully developed, and they must not use the vehicle safety belts without
a suitable ch ild restra int.
It is us ually best to put these children in ap­
propriate booster seats. Be sure the booster
seat meets all applicab le safety standards.
Booster seats raise the seating position of the
child and reposition bot h the lap and sho ulder
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 chi ld's body is very
important for the ch ild's protection, whether
or not a booster seat is used . Children age 12
and under must always ride in the rear seat.
Ch ildren who are at least 4
ft . 9 in. (S7 in­
ches/1.4S meters) tall can generally use the
vehicle's three po int lap and shoulder be lts .
Neve r use the lap belt portion of the veh icle's
safety be lt alone to restrain any child, regard­
l ess of how b ig the child is. Always remembe r
that c hildren do not have the pronounced pe l­
vic structure required for the proper function
of lap belt portion of the vehicle's three point
lap and shoulder be lts. The child's safety ab ­
solutely requires that a lap be lt portion of the
safety belt be fastened snugly and as low as
possib le around the pelvis . Never let the lap
be lt po rtion of the safety belt pass over the
chi ld's stomach or abdomen.
In a crash, airbags must inflate within a blink
of an eye and with cons iderable force . In order
to do its job, the airbag needs room to inflate
so t hat it will be there to p rotect the occupant
as the occupant moves forw ard into the air­
bag.
A vehicle occupant who is out of position and
too close to the airbag gets in the way of an
i n flat ing airb ag. When an occupant is too
close, he or she wi ll be str uck violen tly and will
receive se rious or possib ly even fatal in ­
jury .
In orde r fo r the ai rb ag to offer protect ion, i t is
i mpor tan t t hat a ll vehicle occupants, espe cial­
ly any children, who m ust be in the front seat
because of exceptiona l circumstances , be
proper ly restrained and as fa r 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 prov ide supplemental protection
in ce rtain frontal collisions .
.&, WARNING
Not using a booste r seat, using the boos ­
ter seat imp roperly, in co rrectly installing a
boos ter seat or using the vehicle sa fety
belt imp roperly increases the risk of seri­
ous persona l injury and death in a collision
or other emergency situat ion. To he lp re­
d uce the risk of serio us personal injury
and/or death:
- The shou lder belt must lie as close to the
center of the ch ild's collar bone as possi­
b le and must lie flat and snug on the up­
per body . It must neve r lie across the
throat or neck . The lap belt must lie
across the pe lvis and neve r ac ross t he
s tomach o r abdomen. Make sure t he belt
liesflat and snug.Pullon thebelt to
tighten if necessary.
- Failure to p roperly ro ute s afe ty belts
over a child's body wi ll ca use seve re inj u­
ries in an accident o r other emergency
situation ¢
page 136.
-The rear side o f the child sa fety seat
should be pos itioned as close as possib le
to the backrest on the vehicle seat. Ad­
just or remove the rear seat head re­ straint if it is diffic ult to install the ch ild
seat with the head restraint in p lace
c::;, page 63 . Install t he head rest raint
aga in immediately once the ch ild seat is
removed . D riving without head restraints
or w ith head restra ints th at ar e not prop­

Installing a child safety
seat
Securing a child safety seat using a
safety belt
Safety belts for the rear seats and the front
passenger's seat can be locked with the con­ vertible locking retractor to properly secure
child safety seats.
The safety belts emergency locking retractors
for the rear seats safety belts and for the
Child Safety 175
front passenger's seat safety belt have a con­
vertible locking retractor for child restraints.
The safety belt must be locked so that belt
webbing cannot unreel. The retractor can be
activated to lock the safety belt and prevent
the safety belt webbing from loosening up
during normal driving. A child safety seat can
only be properly installed when the safety belt
is locked so that the child and child safety
seat will stay in place .
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 weight.
A WARNING
=
Improperly installed child safety seats in-
crease the risk of serious personal injury
and death in a collision.
- Always make sure that the safety belt re­
tractor is locked when installing a child
safety seat. An unlocked safety belt re­
tractor cannot hold the child safety seat in place during normal driving or in a
crash .
- Always buckle the child safety seat firmly
in place even if a child is not sitting in it.
A loose child safety seat can fly around
during a sudden stop or in a collision.
- Always make sure that the rear seat
backrest to which the center rear safety
belt is attached is securely latched when­
ever the rear center safety belt is being
used to secure a child restraint.
-If the backrest is not securely latched,
the child and the child restraint will be
thrown forward together with the back­
rest and will strike parts of the vehicle
interior. The child can be seriously in­
jured or killed.
- Never install rearward-facing child safety
seats or infant carriers on the front pas­
senger seat. A child will be seriously in­
jured and can be killed when the passen- ger airbag inflates. .,_ •

-Always be especially careful if you must
install a rearward facing child safety seat
on the front passenger seat in exception­
al circumstances.
- A tight tether strap on a rearward-facing
child restraint attached to the front pas­
senger seat can put too much pressure
on the weight-mat in the seat and regis­
ter a heavier weight in the Advanced Air­
bag System. The heavier weight regis­
tered can make the system work as
though an adult were on the seat and de­ ploy the Advanced Airbag when it must
be suppressed causing serious or even
fatal injury to the child.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
time whenever the ignition is switched
on.
- If the PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the rearward-facing child
safety seat in a rear seating position and
have the airbag system inspected by your
authorized Audi dealer.
Activating the convertible lock ing
retractor
Use the convertible locking retractor to se­
cure a child restraint.
Always heed the child safety seat manufactur­
er's instructions when installing a child re­
straint in your vehicle. To activate the conver­
tible locking retractor:
.. Place the child restraint on a seat, prefera­
bly on the rear seat.
.. Slowly pull the belt
all the way out.
.. Route it around or through the child re­
straint belt path¢.&,_.
.. Push the child safety seat down with your
full weight to get the safety belt really tight.
.. Insert the belt tongue into the buckle for
that seating position.
.. Guide the safety belt back into the retractor
until the belt lies flat and snug on the child
safety seat .
Child Safety 177
.. You should hear a "clicking" noise as the
belt winds back into the inertia reel. Test the
convertible locking retractor by pulling on
the belt. You should no longer be able to
pull the belt out of the retractor. The con­
vertible locking retractor is now activated .
.. Make sure that the red release button is fac­
ing away from the child restraint so that it
can be unbuckled quickly.
.. Pull on the belt to make sure the safety belt
is properly tight and fastened so that the
seat cannot move forward or sideways more
than one inch (2.5 cm).
A WARNING
Using the wrong child restraint or an im­
properly installed child restraint can cause
serious personal injury or death in a crash.
- Always make sure that the safety belt re-
tractor is locked when installing a child
safety seat. An unlocked safety belt re­
tractor cannot hold the child safety seat in place during normal driving or in a
crash.
- Always buckle the child safety seat firmly
in place even if a child is not sitting in it.
A loose child safety seat can fly around
during a sudden stop or in a crash.
- Always make sure the seat backrest to
which the child restraint is installed is in
an upright position and securely latched
into place and cannot fold forward. Oth­
erwise, the seatback with the child safety
seat attached to it could fly forward in
the event of an accident or other emer­
gency situation .

LATCH Lower
anchorages and tether
for children
Child Restraint System anchors and how
are they related to child safety
To provide a s impler and more pract icable way
to attach the child restraint on the vehicle
seat, Federal regu lations require special lower
anchorages in vehicles and dev ices on new
child restraints to attach to the vehicle ancho­
rages.
The combination of the tether anchorages and
the lower anchorages is now generally called
the
LA TCH system for "Lower Anchorages and
Tethers for Children ."
F orward-facing child restraints manufactured
after September 1, 1999, are required by U.S.
federal regulations to comply with new ch ild
head movement performance requirements .
T hese new performance requirements make a
tether necessary on most new child seats.
I nstalling a chi ld restraint that requires a top
tether without one can seriously impair the
performance of the chi ld restraint and its ab il­
ity to protect the child in a co llision . Installing
a child restraint that requires a top tether
without the top tether may be a v iolation of
state law.
Ch ild restraint manufacturers offer LATCH
lower anchorages on their ch ild seats with
hook -on or push-on connectors attached to
adj ustable straps.
In addition to the LATCH lower anchorages,
these child restraint systems usually require
the use of tether straps to help keep the child
restra int firmly in place .
A WARNING
Improper insta llation of chi ld restraints
w ill increase the risk of inju ry and death in
a crash.
- Always follow the instructions p rov ided
by the manufacturer of the ch ild re-
Child S afety 1 79
straint you intend to install in your vehi­
cle.
- Never install a chi ld restraint without a
properly attached top tether strap if the
child restraint manufacturer's instruc­
tions require the top tether strap to be
used.
- Improper use of child restraint LATC H
lower anchorage points can lead to injury
in a collision . The LATC H lowe r anchorage
points ar e designed to withstand on ly
those loads imposed by correctly fitted
child restraints.
- Never mo unt two ch ild restra int systems
on one LATC H lower anchorage point.
- Never secure or a ttach any luggage or
o ther item to the LATCH lower anchorag­
es.
a) Tips
In Canada, the terms "top tether" with
"lower u niversal anchorages" (or "lower
universa l anchorage ba rs") are used to de­
scribe the sys tem.
- In other countries, the t erm " ISOFIX" is
used to describe the lower a nch o rages.

Lower anchorages secure the child restraint in
the seat without using the vehicle 's safety
belts. Anchorages provide a secure and easy­
to-use attachment and m inim ize the possibili­
ty of improper child restraint installation .
All chi ld restraints manufactured after Sep­
tember 1 , 2002, must have lower anchorage
attachments for the
LATCH system .
Remember that the lower anchorage points
are only intended for installation and attach­ ment of child restraints specifically certified
for use w ith
LATCH lower anchorages. Child
restra ints that are not equipped with the low­
e r ancho rage attachments can still be instal- led in compliance with the child restraint
manufacturer's instructions on using vehicle
safety belts
.
A WARNING
-Improper use of LATCH lower anchorages
can cause serious personal injury in an ac­
cident.
- Always carefully follow the child re­
straints manufacturer's instructions for
proper installation of the child restraint
