56 Seats and Restraints
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.
SeeWhere to Put the Restraint 049 for
additional information.
Securing a Child Restraint with the
LATCH System
{Warning
A child could be seriously injured or killed
in a crash if the child restraint is not
properly attached to the vehicle using
either the LATCH anchors or the vehicle
seat belt. Follow the instructions that
came with the child restraint and the
instructions in this manual.
{Warning
To reduce the risk of serious or fatal
injuries during a crash, do not attach
more than one child restraint to a single
anchor. Attaching more than one child
restraint to a single anchor could cause
(Continued)
Warning (Continued)
the anchor or attachment to come loose
or even break during a crash. A child or
others could be injured.
{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
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 seat 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
(Continued)
Warning (Continued)
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 seat belts. This may
damage these parts. If necessary, move
buckled seat 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 seat belt buckled. This
could damage the seat belt or the seat.
Unbuckle and return the seat 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 049.

58 Seats and Restraints
If the position you are using has a
fixed head restraint and you are
using a dual tether, route the
tether around the sides of the head
restraint.
If the child restraint is installed next
to a center seat, make sure the top
tether does not interfere with the
center seating position shoulder
belt/retractor. If it does, find
another suitable seating position to
install the child restraint.
3.4. Adjust the top tether to its fulllength and attach the top tether
hook to the anchor. Make sure that you secure the top tether to the
top tether anchor and not to the
seatback latch.
3.5. Push rearward on the seatback until it locks into its upright position.
Push and pull on the seatback to
make sure it is secured properly.
4. 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 seat
belt and the top tether. Refer to your
child restraint manufacturer instructions
and Securing Child Restraints (With the
Seat Belt in the Rear Seat) 064 or
Securing Child Restraints (With the Seat
Belt in the Front Seat) 069.
5. Tighten the top tether.
6. 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.
Extended Cab with Rear Seats
{Warning
Never secure a rear-facing or
forward-facing child restraint in the left
rear seating position in an extended cab
model. This seating position is not
suitable for child restraint installation.
The seat cushion is too short to properly
support a rear-facing or forward-facing
child restraint. A child could be seriously
injured or killed in a sudden stop or
crash.
A booster seat can be used in the left or
right rear seating position if the base of
the booster seat fits on the seat cushion
and does not extend past the front edge.
If it does, it should be installed in the
right rear seating position using the seat
cushion extension. Only install a booster
seat in either rear seating position if it
can be properly installed according to the
child restraint manufacturer’s instructions.
A rear-facing or forward-facing child
restraint can be installed in the right rear
seating position using the seat cushion

child restraint does not have lower
attachments, secure the child restraint
with the seat belt and the top tether (if
appropriate). See Securing Child
Restraints (With the Seat Belt in the Rear
Seat) 064 or
Securing Child Restraints (With the Seat
Belt in the Front Seat) 069. 6. Tighten the top tether. The child
restraint instructions will show you how.
7. Before placing a child in the child restraint, make sure it is securely held in
place. To check, grasp the child restraint

Removal and Reinstallation” at the end
of this section.
Extended Cab without Rear Seats
{Warning
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger 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 right
front passenger airbag inflates and the
passenger seat is in a forward position.

Warning (Continued)
Even if the passenger sensing system has
turned off the right front 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.
Since this 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 your vehicle,
even if the airbag is off.
SeePassenger Sensing System 039 for
additional information.
The vehicle has a front outboard passenger
frontal airbag and a passenger sensing
system. The passenger sensing system is
designed to turn off the front passenger
frontal airbag when an infant in a
rear-facing infant seat or a small child in a
forward-facing child restraint or booster seat
is detected. See Securing Child Restraints
(With the Seat Belt in the Rear Seat) 064 or
Securing Child Restraints (With the Seat Belt
in the Front Seat) 069 and
Passenger Sensing System 039 for important seat information and additional
information on installing a child restraint in
the front passenger position.
1. Put the child restraint on the right front passenger seat.
2. If the child restraint manufacturer's instructions recommend that the top
tether be attached, attach and tighten
the top tether hook to the top tether
anchor.
2.1. Route the top tether according to your child restraint instructions and
the following instructions:
If you are using a single tether,
raise the headrest or head restraint
and route the tether under the
headrest or head restraint and in
between the headrest or head
restraint posts.
If you are using a dual tether, route
the tether around the headrest or
head restraint.
If the child restraint is installed next
to a center seat, make sure the top
tether does not interfere with the
center seating position shoulder
belt/retractor. If it does, find
another suitable seating position to
install the child restraint.

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 (With
the Seat Belt in the Rear Seat)
When securing a child restraint with the
seat belts in a rear seat 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) 051 for how and where to
install the child restraint using LATCH. If a
child restraint is secured in the vehicle using
a seat belt and it uses a top tether, see
Lower Anchors and Tethers for Children
(LATCH System) 051 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
tether must be anchored.
In Canada, the law requires that
forward-facing child restraints have a top
tether, and that the tether be attached.
If the child restraint or vehicle seat position
does not have the LATCH system, you will
be using the seat belt to secure the child
restraint. Be sure to follow the instructions
that came with the child restraint.
If more than one child restraint needs to be
installed in the rear seat, be sure to read
Where to Put the Restraint 049.
