3-58 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.
In order to use the LATCH system
in your vehicle, you need a
child restraint that has LATCH
attachments. The child restraint
manufacturer will provide you
with instructions on how to use the
child restraint and its attachments.
The following explains how to
attach a child restraint with these
attachments in your vehicle.
Not all vehicle seating positions or
child restraints have lower anchors
and attachments or top tether
anchors and attachments.Lower Anchors
Lower anchors (A) 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 (B).
Top Tether Anchor
A top tether (A, C) anchors the
top of the child restraint to the
vehicle. A top tether anchor is built
into the vehicle. The top tether
attachment (B) 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 3-59
Your child restraint may have
a single tether (A) or a dual
tether (C). Either will have a
single attachment (B) 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

For regular cab models, the top
tether anchors are located under
covers on the back panel behind
the passenger seat. Remove the
trim plug to access the anchor.
Be sure to use an anchor located
on the same side of the vehicle as
the seating position where the child
restraint will be placed.
Crew Cab Shown, Extended CabSimilar For crew and extended cab models,
the top tether anchors are the loops
located 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 in the vehicle.
Be sure to use an anchor (loop)
located on the same side of the
vehicle as the seating position
where the child restraint will be
placed.
Be sure to read the instructions
following 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 3‑56 for
additional information.

Securing a Child Restraint
Designed for the LATCH
System
{WARNING
If a LATCH-type child restraint is
not attached to anchors, 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.
{WARNING
Do not attach more than one
child restraint to a single anchor,
except for the center top tether
anchors in the crew and extended
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
and the safety belt continues to
tighten. 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,
if the vehicle has one, after the
child restraint has been installed.
Notice: 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.

it is securely held in place.
To check, grasp the child
restraint at the LATCH 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 and Extended Cab Models
1. Attach and tighten the
lower attachments to the
lower anchors. If the child
restraint does not have lower
attachments or the desired
seating position does not have
lower anchors, secure the child
restraint with the top tether and
the safety belts. Refer to your
child restraint manufacturer
instructions and the instructions
in this manual.
1.1. Find the lower anchors for the desired seating
position.
1.2. Put the child restraint on the seat.
1.3. Attach and tighten the lower attachments on the child
restraint to the lower
anchors. 2. If the child restraint manufacturer
recommends that the top tether
be attached, attach and tighten
the top tether to the top tether
anchor (loop), if your vehicle has
one. Refer to the child restraint
instructions and the following
steps:

2.4. Tighten the top tetherwhen and as the child
restraint manufacturer's
instructions say.
When the top tether is
tightened, the anchor (loop)
may bend. This is normal
and will not damage the
vehicle.
3. Before placing a child in the child restraint, make sure
it is securely held in place.
To check, grasp the child
restraint at the LATCH 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.Replacing LATCH System
Parts After a Crash
{WARNING
A crash can damage the
LATCH system in the vehicle.
A damaged LATCH system may
not properly secure the child
restraint, resulting in serious
injury or even death in a crash.
To help make sure the LATCH
system is working properly after
a crash, see your dealer to have
the system inspected and any
necessary replacements made
as soon as possible.
If the vehicle has the LATCH system
and it was being used during a
crash, new LATCH system parts
may be needed.
New parts and repairs may be
necessary even if the LATCH
system was not being used at
the time of the crash.
Securing Child Restraints
(Rear Seat Position)
When securing a child restraint in
a rear seating position, study the
instructions that came with the
child restraint to make sure it is
compatible with this vehicle.
If the child restraint has the
LATCH system, see Lower Anchors
and Tethers for Children (LATCH
System) on page 3‑57 for how and
where to install the child restraint
using LATCH. If a child restraint
is secured in the vehicle using a
safety belt and it uses a top tether,
see Lower Anchors and Tethers
for Children (LATCH System) on
page 3‑57 for top tether anchor
locations.
Do not secure a child seat in a
position without a top tether anchor
if a national or local law requires
that the top tether be anchored, or if
the instructions that come with the
child restraint say that the top strap
must be anchored.

In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be

the LATCH system, you will be
using the safety 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.
If more than one child restraint
needs to be installed in the rear
seat, be sure to readWhere to
Put the Restraint on page 3‑56.
1. Put the child 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.
For crew cab second row
seatings positions, tilt the latch
plate to adjust the belt if needed.3. Push the latch plate into the
buckle until it clicks.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
