3-46 Seats and Restraints
When installing a child restraint with
a top tether, you must also use
either the lower anchors or the
safety belts to properly secure the
child restraint. A child restraint must
never be installed using only the top
tether and anchor.
The LATCH anchorage system can
be used until the combined weight
of the child plus the child restraint is
29.5 kg (65 lbs). Use the safety belt
alone instead of the LATCH
anchorage system once the
combined weight is more than
29.5 kg (65 lbs).
The following explains how to attach
a child restraint with these
attachments in the vehicle.
Not all vehicle seating positions or
child restraints have lower anchors
and attachments or top tether
anchors and attachments.Lower Anchors
Lower anchors (1) are metal bars
built into the vehicle. There are two
lower anchors for each LATCH
seating position that will
accommodate a child restraint with
lower attachments (2).
Top Tether Anchor
A top tether (3, 4) anchors the top of
the child restraint to the vehicle.
A top tether anchor is built into the
vehicle. The top tether
attachment (2) on the child restraint
connects to the top tether anchor in
the vehicle in order to reduce the
forward movement and rotation of
the child restraint during driving or in
a crash.

Seats and Restraints 3-47
The child restraint may have a
single tether (3) or a dual tether (4).
Either will have a single
attachment (2) to secure the top
tether to the anchor.
Some child restraints that have a
top tether are designed for use with
or without the top tether being
attached. Others require the top
tether always to be attached. In
Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached. Be sure to read and follow
the instructions for your child
restraint.Lower Anchor and Top Tether

To assist in locating the lower
anchors on crew cab models, each
seating position with lower anchors has two labels near the crease
between the seatback and the seat
cushion.
For double cab models, the rear
outboard seating positions have
exposed metal lower anchors in the
crease between the seatback and
the seat cushion.
For regular cab models, there is an
anchor symbol on the cover to
assist you in locating the top tether
anchors.
Do not install a child restraint in the

to use an anchor on the same side
of the vehicle as the seating
position where the child restraint will
be placed.
Crew Cab Shown, Double CabSimilar
For crew and double cab models,
the top tether anchors are the loops
near the top of the seatback for
each rear seating position. These
loops will be used to route the top
tether through, as well as to secure
the top tether to the vehicle. Be sure
to use the anchor (loop) on the same side of the vehicle as the
seating position where the child
restraint will be placed.
Be sure to read the following
instructions to properly install a child
restraint using these loops.
Do not secure a child restraint in a
position without a top tether anchor
if a national or local law requires
that the top tether be attached, or if
the instructions that come with the
child restraint say that the top tether
must be attached.
According to accident statistics,
children and infants are safer when
properly restrained in a child
restraint system or infant restraint
system secured in a rear seating
position. See
Where to Put the
Restraint on page 3-43 for
additional information.
Securing a Child Restraint
Designed for the LATCH
System
{Warning
If a LATCH-type child restraint is
not attached to anchors or with
the safety belt, the child restraint
will not be able to protect the child
correctly. In a crash, the child
could be seriously injured or
killed. Install a LATCH-type child
restraint properly using the
anchors, or use the vehicle safety
belts to secure the restraint,
following the instructions that
came with the child restraint and
the instructions in this manual.

3-50 Seats and Restraints
{Warning
Do not attach more than one child
restraint to a single anchor,
except for the center top tether
anchors in the crew and double
cabs. Attaching more than one
child restraint to a single anchor
could cause the anchor or
attachment to come loose or even
break during a crash. A child or
others could be injured. To reduce
the risk of serious or fatal injuries
during a crash, attach only one
child restraint per anchor.
{Warning
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck. The
shoulder belt can tighten but
cannot be loosened if it is locked.
The shoulder belt locks when it is(Continued)
Warning (Continued)
pulled all the way out of the
retractor. It unlocks when the
shoulder belt is allowed to go all
the way back into the retractor,
but it cannot do this if it is
wrapped around a child’s neck.
If the shoulder belt is locked and
tightened around a child’s neck,
the only way to loosen the belt is
to cut it.
Buckle any unused safety belts
behind the child restraint so
children cannot reach them. Pull
the shoulder belt all the way out
of the retractor to set the lock,
and tighten the belt behind the
child restraint after the child
restraint has been installed.
{Caution
Do not let the LATCH
attachments rub against the
vehicle’s safety belts. This may
damage these parts. If necessary,
move buckled safety belts to
avoid rubbing the LATCH
attachments.
Do not fold the empty rear seat
with a safety belt buckled. This
could damage the safety belt or
the seat. Unbuckle and return the
safety belt to its stowed position,
before folding the seat.
If you need to secure more than one
child restraint in the rear seat, see
Where to Put the Restraint on
page 3-43.

This system is designed to make
installation of child restraints easier.
When using lower anchors, do not
use the vehicle's safety belts.
Instead use the vehicle's anchors
and child restraint attachments to
secure the restraints. Some
restraints also use another vehicle
anchor to secure a top tether.
Regular Cab Models

recommends that the top tether
be attached, attach and tighten
the top tether to the top tether
anchor, if your vehicle has one.

If the position you are using
has an adjustable head
restraint and you are using
a dual tether, route the

securely held in place. To check,
grasp the child restraint at the
safety belt path and attempt to
move it side to side and back
and forth. There should be no
more than 2.5 cm (1 in) of
movement for proper installation. Crew Cab Models
