Child safety
_& 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 cou ld play with unused rear seat
safety belts and become entangled. 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 re­
straint is installed.
- Never activate the convertible locking re­ tractor when routing the safety belts around
the head restraints.
- Never let anyone sit at the center rear seat­
ing position if the center rear safety belt has
been routed around a rear head restraint.
Child seats
Infant seats
Babies and infants up to about one year old and
20 lbs. or 9 kg need special rearward-facing
child restraints that support the back, neck and
head in a crash.
Fig. 139 Schematic overview: rearward-facing infant seat,
properly installed on the rear seat
.. When using the vehicle safety be lt 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
c::> page 182 or install the seat using the LATCH
attachments.
.. Push the child safety seat down with your full
weight to get the safety belt really tight so that
178
the seat cannot move forward or sideways more
than one inch (2.5 cm).
.. Secure unused safety belts on the rear seat
c::>page 177.
Infants up to about one year (20 lbs. or 9 kg) are
best protected in special infant carriers and child
safety seats designed for their age group. Many
experts believe that infants and small children
should ride only in special restraints in which the
ch ild faces the back of the vehicle. These infant
seats support the baby's back, neck and head in a
crash
c::> fig. 139.
The airbag on the passenger side makes the front
seat a potent ially dangerous place for a child to
ride . The front seat is not the safest place for a
child in a forward-facing ch ild seat.
It is a very
dangerous place for an infant or a Larger child in
a rearward-facing 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 kil­ led 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
c::> page 149, Child restraints on the
front seat -some important things to
know .
-Always install rear-facing chi ld safety seats
or infant carriers on the rear seat.
- Never install a rear-fac ing ch ild restraint 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.
- If you must install a rearward facing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immediately install

Booster seats and safety belts
Properly used booster seats can help protect
children weighing be tween about 40 lbs. and 80
lbs . (18 kg and 36 kg) who are less than 4
ft. 9
in . (57 inches/1 .45 meters) tall .
Fig. 14 2 Re ar seat: child pro perl y restrain ed in a booster
seat
T he vehicle's safety belts alone will not fit most
children unti l they are at least 4
ft . 9 in . (57 in­
ches/1.45 meters) tall and we igh about 80 lbs .
(36 kg) . Booster seats raise these children up so
that the safety bel t will pass properly over the
stronger parts of their bodies and the safety belt
can help protect them in a c rash.
.,. Do not use the co nvertib le locking retractor
when using the vehicle's safety bel t to restra in
a ch ild on a boos ter sea t.
.. The shoulder be lt must lie as close to the cen­
te r of the child's co llar bone as possible and
must lie flat and snug on the upper body. It
must never lie across the throat or neck. The
lap belt must lie across the pelvis and never
ac ross the stomach or abdomen . Make sure the
belt lies flat and snug . Pull on the belt to tight­
en if necessary .
.,. If you must transpo rt an older chi ld in a boos­
ter seat on the front passenger sea t, you can
use the safety belt height adj ustmen t to help
adjust the shoulder port ion properly .
Child sa fe ty
.. Secure unused sa fety belts on the rear seat
i=> page 177.
Childre n up to at least 8 yea rs old (over 40 lbs or
18 kg) are best protected in child safety seats de ­
s igned for their age and weight . Experts say that
the skeleta l structure, particularly the pelvis, of
these chi ldren is not f ully deve loped, and they
must not use the vehicle safety belts without a
su itable child restraint .
It is usually best to put these child ren in appro­
priate booster seats . Be sure the booster seat
meets all applicab le safety standards.
Booster seats ra ise the seating position of the
child and reposit ion both the lap and shoulder
parts of the safety belt so that they pass across
the chi ld's body in the right places. The routing of
the be lt over the chi ld 's body is very important
for the ch ild's protection, whether or not a boos ­
te r 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 inches/
1.45 meters) tall can generally use the vehicle's
th ree po int lap and shoulder be lts . N ever use the
lap belt portion of the veh icle's safety belt a lone
to re strain any child , regardles s of how b ig the
c hi ld i s. A lways remember that c hildren do no t
have the pronounced pe lv ic struct ure required for
the p roper function of lap belt port ion of the ve­
hicle 's t hree point lap and shoulder be lts . The
c h ild 's safety abso lutely requires that a lap belt
portion of the safety belt be fastened snug ly and
as low as possible around the pelvis . Never let
the lap belt portion of the safety belt pass over
the ch ild's stomach or abdomen .
In a crash, a irbags 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 the re to p rotect the occ upant as th e occu­
pant moves fo rward into the airbag .
A vehicle occupant who is out of posit ion and too
close to the a irbag gets in the way of an inflating
airbag . When an occupan t is too close, he o r she
will be struck violent ly and w ill receive ser ious or
poss ibly eve n fa ta l injury. .,,.
181

Child safet y
In order for the airbag to offer protection, it is
important that all vehicle occupants, especially
any children, who must be in the front seat be­
cause of except ional circumstances, be proper ly
restrained and as far away from the airbag as
possible . By keeping room between the child's
body and the front of the passenger compart­
ment, the airbag can inflate comp letely and pro­
vide supp lemental protection in ce rtain frontal
coll is ions .
A WARNING
Not using a booster seat, using the booster
seat improperly, incorrect ly installing a boos­
ter seat or using the vehicle safety belt im­
properly increases the risk of serious personal
injury and death in a collision or other emer­
gency situat ion. To help reduce the risk of se­
r ious personal injury and/or death:
- The shoulder belt must lie as close to the
center of the child's collar bone as possible
and must lie flat and snug on the upper
body .
It must never lie across the throat or
neck. The lap belt must lie across the pelv is
and never across the stomach or abdomen.
Make sure that the be lt lies flat and snug.
Pull on the belt to tighten i f necessa ry .
- Failure to properly route safety be lts over a
child 's body will cause severe injuries in an
accident or other emergency sit uation
¢ page 140.
- The rear side of the child safety seat shou ld
be positioned as close as possible to the
backrest on the vehicle seat.
- For adjustable head restraints: adjust or re ­
move the rear seat head restraint if it is dif­
ficult to install the child seat with the head
restraint in place¢
page 56. Install the
head restraint again immediately once the
child seat is removed . Driv ing without head
restraints or with head restraints that are
not properly adjusted increases the r isk of
serious o r fatal neck injury dramatically .
- Children on the front seat of any car, even
with Advanced Airbags, can be ser iously in­
jured or even killed when an airbag inflates.
- Never let a child stand or knee l on any seat,
for example the front seat.
182
-
- Never let a child ride in the cargo area of
your veh icle.
- Always remember that a child leaning for­
ward, sitting sideways or out of position in any way during an acc ident can be struck by
a deploying airbag. This will resu lt in serious
personal injury or death.
- If you must install a booster seat on the
front passenger seat because of exceptional
circumstances the
PASSENGER AIR BAG
OFF
li ght must come on and stay on, when­
eve r the ign it ion is switched on.
- If the
PASSENGER AIR B AG OF F light does
not come on and stay on, perform the
checks described ¢
