92 Seats and Restraints
Forward-Facing Child Seat
A forward-facing child restraint
provides restraint for the child's
body with the harness. Booster Seats
A belt-positioning booster seat is
used for children who have
outgrown their forward-facing child
restraint. Boosters are designed to
improve the fit of the vehicle's safety
belt system until the child is large
enough for the vehicle safety belts
to fit properly without a booster seat.
See the safety belt fit test in Older
Children 0 87 . Securing an Add-On Child
Restraint in the Vehicle
{ WarningA child can be seriously injured or
killed in a crash if the child
restraint is not properly secured in
the vehicle. Secure the child
restraint properly in the vehicle
using the vehicle ’ s safety belt or
LATCH system, following the
instructions that came with that
child restraint and the instructions
in this manual.
To help reduce the chance of injury,
the child restraint must be secured
in the vehicle. Child restraint
systems must be secured in vehicle
seats by lap belts or the lap belt
portion of a lap-shoulder belt, or by
the LATCH system. See Lower
Anchors and Tethers for Children
(LATCH System) 0 95 for more
information. Children can be
endangered in a crash if the child
restraint is not properly secured in
the vehicle.

Seats and Restraints 93When securing an add-on child
restraint, refer to the instructions
that come with the restraint which
may be on the restraint itself or in a
booklet, or both, and to this manual.
The child restraint instructions are
important, so if they are not
available, obtain a replacement
copy from the manufacturer.
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
the vehicle — even when no child is
in it.
In some areas of the United States
and Canada, Certified Child
Passenger Safety Technicians
(CPSTs) are available to inspect
and demonstrate how to correctly
use and install child restraints. In
the U.S., refer to the National
Highway Traffic Safety
Administration (NHTSA) website to
locate the nearest child safety seat
inspection station. For CPST
availability in Canada, check with
Transport Canada or the Provincial
Ministry of Transportation office. Securing the Child Within the
Child Restraint
{ WarningA child can be seriously injured or
killed in a crash if the child is not
properly secured in the child
restraint. Secure the child
properly following the instructions
that came with that child restraint.
Where to Put the
Restraint According to accident statistics,
children and infants are safer when
properly restrained in an appropriate
child restraint secured in a rear
seating position.
Whenever possible, children aged
12 and under should be secured in
a rear seating position.
If a child restraint is secured in the
front outboard passenger seat, and
the vehicle has a switch on the
passenger side instrument panel
endcap to manually turn off the front outboard passenger airbag, see
Airbag On-Off Switch 0 79 and
Securing Child Restraints (With the
Safety Belt in the Center Front Seat)
0 110 or Securing Child Restraints
(With the Safety Belt in the Rear
Seat) 0 106 or Securing Child
Restraints (With the Safety Belt in
the Front Passenger Seat) 0 110 for
more information, including
important safety information.
Never put a rear-facing child seat in
the front. This is because the risk to
the rear-facing child is so great,
if the airbag deploys.
{ WarningA child in a rear-facing child
restraint can be seriously injured
or killed if the front outboard
passenger frontal airbag inflates.
This is because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the front

94 Seats and Restraints Warning (Continued)outboard passenger frontal airbag
inflates and the passenger seat is
in a forward position.
Even if the passenger sensing
system or airbag switch has
turned off the front outboard
passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though it is
turned off.
Secure rear-facing child restraints
in a rear seat, even if the airbag
is off. If you secure a
forward-facing child restraint in
the front outboard passenger
seat, always move the seat as far
back as it will go. It is better to
secure the child restraint in a
rear seat. { WarningA child in a child restraint in the
center front seat can be badly
injured or killed by the frontal
airbags if they inflate. Never
secure a child restraint in the
center front seat. It is always
better to secure a child restraint in
a rear seat.
Do not use child restraints in the
center front seat position.
When securing a child restraint in a
rear seating position, study the
instructions that came with your
child restraint to make sure it is
compatible with this vehicle.
Child restraints and booster seats
vary considerably in size, and some
may fit in certain seating positions
better than others.
Depending on where you place the
child restraint and the size of the
child restraint, you may not be able
to access adjacent safety belts or
LATCH anchors for additional
passengers or child restraints. Adjacent seating positions should
not be used if the child restraint
prevents access to or interferes with
the routing of the safety belt.
If the vehicle does not have a rear
seat that will accommodate a
rear-facing child restraint, a
rear-facing child restraint should not
be installed in the vehicle, even if
the airbag is off.
Wherever a child restraint is
installed, be sure to follow the
instructions that came with the child
restraint system and secure the
child restraint system 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.

Lower Anchors and
Tethers for Children
(LATCH System) The LATCH system secures a child
restraint during driving or in a crash.
LATCH attachments on the child
restraint are used to attach the child
restraint to the anchors in the
vehicle. This system is designed to
make installation of a child restraint
easier.
In order to use the LATCH system in
your vehicle, you need a child
restraint that has LATCH
attachments. LATCH-compatible
rear-facing and forward-facing child
seats can be properly installed
using either the LATCH anchors or
the vehicle ’ s safety belts. Do not
use both the safety belts and the
LATCH anchorage system to secure
a rear-facing or forward-facing
child seat.
Booster seats use the vehicle ’ s
safety belts to secure the child in
the booster seat. If the manufacturer
recommends that the booster seat
be secured with the LATCH system, this can be done as long as the
booster seat can be positioned
properly and there is no interference
with the proper positioning of the
lap-shoulder belt on the child.
Make sure to follow the instructions
that came with the child restraint,
and also the instructions in this
manual.
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 attached using only the top
tether.
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).
See Securing Child Restraints (With
the Safety Belt in the Center Front
Seat) 0 110 or Securing Child
Restraints (With the Safety Belt in
the Rear Seat) 0 106 or Securing Child Restraints (With the Safety
Belt in the Front Passenger Seat)
0 110 .
Child restraints built after March
2014 will be labeled with the
specific child weight up to which the
LATCH system can be used to
install the restraint.
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. In this
case, the safety belt must be used
(with top tether where available) to
secure the child restraint.

96 Seats and Restraints 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.
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.

Regular Cab
For regular cab models, the top
tether anchors are under covers on
the back panel behind the
passenger seat. Remove the trim
plug to access the anchor. Be sure
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 Cab
Similar
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 0 93 for additional
information.

Seats and Restraints 99Warning (Continued)restraint properly using the
anchors, or use the vehicle's
safety belts to secure the
restraint, following the instructions
that came with the child restraint
and the instructions in this
manual.
{ WarningDo 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. { WarningChildren 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
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. CautionDo 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 rear seatback
when the seat is occupied. 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 0 93 .
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
