Safety belts must always be correctly posi­
tioned across the strongest bones of your
body.
~ Always wear safety belts as illustrated and
described in this chapter.
~ Make sure that your safety belts are always
ready for use and are not damaged.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of serious
personal injury and death. Safety belts can
work only when used correctly.
- Always fasten your safety be lts correctly

- Always keep feet in the footwell in front
of the seat while the vehicle is being d riv­
en .
- Never let any person ride with their feet
on the instrument panel or sticking out
the window or on the seat.
- Never remove a safety belt while the ve­
hicle is moving. Doing so will increase
your risk of be ing injured or killed.
- Never wear belts twisted.
- Never wear belts over rigid or breakable
objects in or on your clothing, such as
eye glasses, pens, keys, etc., as these may cause injury.
- Never allow safety belts to become dam­
aged by being caught in door or seat

- Do not wear the shoulder part of the belt
under your arm or otherwise out of posi­
tion .
Safety belts 141
-Several layers of heavy clothing may in­
terfere with correct positioning of belts and reduce the overall effectiveness of
the system .
- Always keep belt buckles free of anything
that may prevent the buckle from latch­
ing securely.
- Never use comfort clips or devices that
create slack in the shoulder belt . Howev­
er, special clips may be requ ired for the
proper use of some child restraint sys­
tems .
- Torn or frayed safety belts can tear, and
damaged belt hardware can break in an
accident. Inspect belts regularly.
If web­
bing, bindings, buckles, or retractors are
damaged, have belts replaced by an au­
thorized Audi dealer.
- Safety belts that have been worn and
loaded in an accident must be replaced
with the correct replacement safety belt
by an authorized Audi dealer. Replace­
ment may be necessary even if damage
cannot be clearly seen. Anchorages that
were loaded must also be inspected.
- Never remove, modify, disassemble, or
try to repair the safety belts you rs elf .
-Always keep the belts clean. Dirty belts may not work properly and can impair
the function of the inertia reel¢

belt.
- Le t the belt retractor wind up the safety belt
webbing.
.,&. WARNING
-A child in a child safety seat installed with
the LATCH lower anchorages or with 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 cause the child serious personal injury and even death.
- Always secure unused rear seat safety
belts out of reach of children in child
seats such as by properly routing them
around the head restraint of the seat
where the child restraint is installed.
- Never activate the switchable locking re­
tractor when routing the safety belts around the head restraints.
- Never let anyone sit at the center rear
seating position if the center rear safety
belt has been routed around a rear head
restra int.

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 . 162 Sche matic overv iew: rearward-fac ing infant
seat, properly installed o n the rear seat
.,. When using the vehicle safety belt to install
a ch ild safety seat, you must first activate
the convertible locking retracto r on the
safety be lt to prevent the child safety seat
from moving
¢ page 177 or install the seat
using the LA T CH attachments.
.,. Push the child safety seat down with your
full weight to get the safety belt rea lly 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
¢page 172.
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
¢ fig . 162.
The airbag on the passenger side makes the
front seat a po tentially dangerous place for a
child to r ide . The front seat is not the safest
p lace for a child in a forward -facing child seat.
It is a very dangerous p lace for an infant or a
l arger ch ild in a rearward-facing seat.
Child Safety 173
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 ¢

174 Child Safety
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 ..,.

176 Child Saf ety
• Secure unused safety belts on the rear seat
9 page 172 .
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 structur e, 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 138.
-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 61 . 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
erly a djusted increases the risk of serious
.
or fatal neck in jury drama tically . ""

-Children on the front seat of any car,
even with Advanced A irbags, can be seri­
ous ly injured or even killed when an a ir­
bag inflates.
- Never let a child stand or kneel on any
seat.
- Never let a child ride in the cargo area of
your vehicle.
- Always remember that a ch ild lean ing
forward, sitt ing sideways or out of posi­
t ion in any way during an acc ident can be
struck by a deploying airbag . This will re­
sult in se rious personal injury or death.
- If you must install a rearward facing
child safety seat o n the front passenger

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 Safet y 177
front passenger's seat safety be lt have a con ­
vertib le locking retractor for child restraints .
The safety belt must be locked so that be lt
webb ing cannot unreel. The retractor can be
activated to lock the safety belt and prevent
the safety belt webbing from loosening up
dur ing normal driv ing . A child safety seat can
on ly be properly insta lled when the safety belt
is locked so that the chi ld and child safety
seat w ill 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, shou ld always ride in the back seat prope r­
ly restrained for the ir age and we ight .
A WARNING
=
Improperly installed chi ld safety seats in-
crease the risk of serious personal injury
and death in a co llision.
- Always make s ure 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 dur ing normal driving or in a
crash .
- Always buckle the child safety seat firmly
in place even if a ch ild is not sitt ing 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
be lt is attached is securely latched when­
ever the rear center safety belt is being
used to secure a ch ild restra int.
- 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 insta ll rearward-facing child safety
seats or infant carriers on the front pas­
senger seat. A child will be serious ly 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:

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

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 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 .
