A WARNING
Not using a booster seat, us ing the booster
seat improperly, incorrectly installing a boos­
ter seat or using the vehicle safety belt im­
properly increases the risk of ser ious personal
injury and death in a collision or other eme r­
gency sit uat ion. To help red uce the risk of se­
rious persona l injury and/or death:
- The shoulder be lt mus t lie as close to the
center of the child's collar bone as possib le
and must lie flat and snug on the upper
body. It must never lie across the throat or
neck . The lap be lt must lie across the pelvis
and never across the stomach or abdomen.
Make sure the belt lies flat and snug. Pull on
the belt to tighten if necessary.
- Failure to proper ly route safety belts over a
child's body will cause severe injuries in an
acc ident or other emergency situation
¢ page 261.
-The rear side of the child safety seat should
be pos itioned as close as possible to the
backrest on the vehicle seat. Adjust or re­
move the rear seat head restraint if it is d if­
ficult to install the child seat with the he ad
restra int in place¢
page 58. Ins tall the
head restraint again immediately once the
child seat is removed . Driving without head
restra ints or w ith head rest raints that are
not properly adjusted increases the risk of
serious or fatal neck injury dramatically.
- Never let a child put the sho ulder belt under
the arm or beh ind the back, because it cou ld
cause severe injur ies in a crash.
- Children on the front seat of any car, even with Advanced Airbags, can be seriously 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.
- Never let a child ride in the ca rgo area o f
you r vehicle.
- Always remember that a child leaning for­
ward, s itting sideways or out of position in

Securing child safety
seats
Securing a child safety seat using a safety
belt
Safety belts for the rear seats and the front pas ­
senger can be locked with the convertible locking
retractor to properly secure child safety seats .
The safety belts for the rea r seats and for the
front passenge r's seat have a conve rtible locking
r etractor for child safety seats. The safety belt
must be locked so that be lt webb ing cannot un ­
r eel. The retractor can be act ivated to lock the
safety belt and prevent the safety belt webbing
from loosening up dur ing norma l dr iving . A ch ild
safety seat can o nly be prope rly installed when
t h e safety be lt is locked so that the c hild and
c hi ld s afety seat will stay in place.
Always remember : Even though your veh icle is
equipped with an Advanced Airbag system, all
c hi ld re n, especially those 12 yea rs and you nger,
sho uld always ride in t he b ack seat p roperly re-
strained for their age and s ize.

::r ' 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 retrac­
tor 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 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 back­
rest to wh ich the center rear safety belt* is
attached is secure ly latched whenever the
rea r cente r safety belt is being used to se­
cur e a ch ild rest raint.
- If the backrest is not securely latched, the
child and the child restraint will be thrown
forwar d toge ther w it h the backrest and will
st rike parts of the vehicle interior. The ch ild
can be se riously in jured or killed .
- Never ins tall rear-f acing chi ld safety sea ts
or infant carriers on the front passen ger
seat . A child will be serious ly inju red and
can be killed when the passenger airbag in­
flates.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the ch ild safety seat and chi ld
against the backrest, center armrest, door
or roof .
- Always install rear-facing child safety seats
o r infant carriers on the rear seat.
- Forward-fac ing ch ild safety seats or infant
carriers installed on the front passenger's
seat may interfere with the deployment of
the a irbag and cause serious injury to the
child .
- It is safe r to install a forward-fac ing ch ild
safety seat on the rear seat .

ge r seat and inst all it prope rly at one of the
rear sea t positions i f the
PASSENGER AIR
BAG OFF~;
light does not stay on whenever
the ignition is switched on .
- Imp roper installat ion of child restra ints can
reduce the ir effectiveness or even prevent
them from providing any protect ion .
- An imprope rly installed child restra int can
interfere with the airbag as it deploys and
serio usly injure or even kill the chi ld.
- Always carefully follow the manufacturer's
instr uctions provided with the child sa fety

LATCH system (lower
anchorages and tethers
for children)
Child Restraint System anchors and how
are they related to child safety
T o p rovide a simp ler and more practicab le way to
attach the ch ild rest raint on the vehicle seat,
Federal regulations require spec ia l lower ancho­
rages in vehicles and devices o n new c hild re­
straints to attach to the vehicle anc horages .
In the United States, the combination of the
tethe r anchorages and the lower anchorages is
now generally called t he LATCH system for
" Lower Anchorages and Tethers for Childre n". In
Canada, the terms "top tether" with "lower un i­
versa l anchorages" (o r "lowe r universa l anchor­
age bars") a re used to descr ibe the system .
In other co untries the term "ISOFIX" is used to
desc ribe the lower anchorages .
Forward-facing chi ld restraints manufactured af­
ter September 1, 1999, are requ ired by U.S . fed­
era l regulations to comply with new child head
movement pe rformance requ iremen ts. These
new pe rformance req uir ements make a tether
necessary on most new ch ild seats.
Installing a c hild restraint t hat requires a top
tethe r withou t one can se riously impa ir the per­
fo rmance of the ch ild rest rai nt and its ab ility to
pro tect the ch ild in a co llision. I nstalling a ch ild

In addition to the LATCH lower anchorages , these
child restraint systems usually require the use of
tether straps to help keep the child restraint
firmly in place.
A WARNING
Improper installation of child restraints will
increase the risk of injury and death in a
crash.
- Always follow the instructions provided by
the manufacturer of the child restraint you intend to install in your vehicle.
- Never install a child restraint without a
properly attached top tether strap if the
child restraint manufacturer's instructions
require the top tether strap to be used.
- Improper use of child restraint LATCH lower
anchorage points can lead to injury in a colli ­
sion . The LATCH lower anchorage points are
designed to withstand only those loads im­
posed by correctly fitted child restraints.
- Never mount two child restraint systems on
one LATCH lower anchorage point.
- Never secure or attach any luggage or other
item to the LATCH lower anchorages.

The tether anchors for the rear seating positions
are located on the backside of the rear seatbacks .
A tether is a straight or V-shaped strap that at­
t aches the top part of a child restraint to special
anchorage points in the vehicle .
The purpose of the tether is to reduce the for­
ward movement of the child restraint in a crash, in order to help reduce the risk of head injury
t ha t could be caused by striking the vehicle inte­
rior .
Forward facing child restraints manufactured af­
ter September 1, 1999, are required by U .S. fed­

new performance requirements make a tether
necessary on most new child safety seats .
