Where to Put the Restraint
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat. We,
therefore, recommend that child restraints be secured
in a rear outside seat position including an infant
riding in a rear-facing infant seat, a child riding in a
forward-facing child seat and an older child riding in a
booster seat.Neverput a rear-facing child restraint
in the front passenger seat. Here is why:
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger’s air bag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating air bag.
Always secure a rear-facing child restraint in a
rear seat outside position.
If you secure a forward-facing child restraint in
the right front seat, always move the front
passenger seat as far back as it will go. It is
better to secure the child restraint in a rear
seat outside position.Wherever you install it, be sure to secure the child
restraint properly.
Keep in mind that an unsecured child restraint can
move around in a collision or sudden stop and injure
people in the vehicle. Be sure to properly secure
any child restraint in your vehicle – even when no child
is in it.
Top Strap
Some child restraints have a top strap, or “top tether.” It
can help restrain the child restraint during a collision.
For it to work, a top strap must be properly anchored to
the vehicle. Some top strap-equipped child restraints
are designed for use with or without the top strap being
anchored. Others require the top strap always to be
anchored. Be sure to read and follow the instructions for
your child restraint. If yours requires that the top strap
be anchored, do not use the restraint unless it is
anchored properly.
If the child restraint does not have a top strap, one can
be obtained, in kit form, for many child restraints.
Ask the child restraint manufacturer whether or not a kit
is available.

In Canada, the law requires that forward-facing child
restraints have a top strap, and that the strap be
anchored. In the United States, some child restraints
also have a top strap. If your child restraint has a
top strap, it should be anchored.
{CAUTION:
Each top tether bracket is designed to anchor
only one child restraint. Attaching more than
one child restraint to a single bracket could
cause the anchor to come loose or even break
during a crash. A child or others could be
injured if this happens. To help prevent injury
to people and damage to your vehicle, attach
only one child restraint per bracket.
Anchor the top strap to one of the following anchor
points. Be sure to use an anchor point located on the
same side of the vehicle as the seating position
where the child restraint will be placed.
Raise the head restraint and route the top strap under
it. SeeHead Restraints on page 1-5.
Once you have the top strap anchored, you will be
ready to secure the child restraint itself. Tighten the top
strap when and as the child restraint manufacturer’s
instructions say.

Lower Anchorages and Top Tethers
for Children (LATCH System)
Your vehicle has the LATCH system. You’ll nd
anchors (A) in the rear outside seat positions.
This system, designed to make installation of child
restraints easier, does not use the vehicle’s safety belts.
Instead, it uses vehicle anchors (A,B) and child
restraint attachments to secure the restraints. Some
restraints also use another vehicle anchor to secure a
top tether strap (C).
1-42

In order to use the LATCH system in your vehicle, you
need a child restraint designed for that system.
To assist you in locating the
lower anchors for this child
restraint system, each
seating position with the
LATCH system has a label
on the seatback at each
lower anchor position.
The labels are located near the base of the rear outside
seat positions.
{CAUTION:
If a LATCH-type child restraint is not attached
to its anchorage points, the restraint will not
be able to protect the child correctly. In a
crash, the child could be seriously injured or
killed. Make sure that a LATCH-type child
restraint is properly installed using the
anchorage points, or use the vehicle’s safety
belts to secure the restraint, following the
instructions that came with that restraint, and
also the instructions in this manual.

Securing a Child Restraint Designed
for the LATCH System
1. Find the LATCH anchorages for the seating
position you want to use, where the bottom of the
seatback meets the back of the seat cushion.
2. Put the child restraint on the seat.
3. Attach and tighten the LATCH attachments on the
child restraint to the LATCH anchorages in the
vehicle. The child restraint instructions will show you
how.
4. If the child restraint is forward-facing, attach and
tighten the top tether to the top tether anchorage.
The child restraint instructions will show you
how. Also seeTop Strap on page 1-39.
5. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, simply unhook the top
tether from the top tether anchorage and then
disconnect the LATCH attachments from the LATCH
anchorages.

If your child restraint is equipped with the LATCH
system, seeLower Anchorages and Top Tethers for
Children (LATCH System) on page 1-42. SeeTop Strap
on page 1-39if the child restraint has one.
There are no top strap anchors at the third row seating
positions. Do not secure a child seat in these positions
if a national or local law requires that the top strap
be anchored, or if the instructions that come with the
child restraint say that the top strap must be anchored.If your child restraint does not have the LATCH system,
you will be using the lap-shoulder belt to secure the
child restraint in this position. Be sure to follow the
instructions that came with the child restraint.
Secure the child in the child restraint when and as the
instructions say.
1. Put the restraint on the seat.
2. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.
1-45

5. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the lap
portion of the belt and feed the shoulder belt back
into the retractor. If you are using a forward-facing
child restraint, you may nd it helpful to use your
knee to push down on the child restraint as you
tighten the belt.6. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, just unbuckle the vehicle’s
safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.

Securing a Child Restraint in the
Center Seat Position
Many child restraints are too wide to be correctly
secured in the center rear seat, although some of them
will t there. If the center seat position is too narrow
for your child restraint, secure it in a rear outside seat
position.
If you secure a child restraint in the center seat position,
follow the instructions inSecuring a Child Restraint in
a Rear Outside Seat Position on page 1-44.
