Warning (Continued)
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
extension in an extended cab model.
Never install a rear-facing or
forward-facing child restraint in the right
rear seating position without the seat
cushion extension.
{Warning
Do not let anyone ride in the front
passenger seat when a rear-facing child
restraint is installed in the right rear
seating position. To properly fit the(Continued)
Warning (Continued)
rear-facing child restraint, the front
seatback will need to be tilted forward
which will not allow a passenger to sit
properly in the front outboard passenger
seat. The passenger could be seriously
injured or killed in a sudden stop or
crash.
{Warning
Do not attach a top tether to the loop
near the top of the seatback and directly
behind the seating position in which the
child restraint is installed in an extended
cab with rear seats. The top tether will
not be able to be properly tightened. See
instructions below for how to properly
attach a top tether.
Extended Cab Rear Seat Cushion Extension
The vehicle is equipped with a headrest that
is used as a seat cushion extension for
installation of child restraints in the right
rear seat.
{Warning
The right rear seat cushion extension is
designed to support the weight of a child
in a child restraint or booster seat. It is
neither designed nor intended to support
the weight of an adult. Use the seat
cushion extension only when a child
restraint or booster seat is installed in
the right rear seating position.
When installing a rear-facing child restraint
in the right rear seating position, move the
front seat all the way forward and tilt the
seatback forward to properly install the child
restraint. See Power Seat Adjustment 023,
Seat Adjustment 023, and Reclining
Seatbacks 024. When a rear-facing child
restraint is installed properly, the front
passenger seat cannot be used.
1. Always install the seat cushion extension in the right rear seating position when
installing a forward-facing or rear-facing
child restraint. Also use the seat cushion
extension for booster seats that extend
past the front edge of the seat cushion.

{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.
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.

Replacing LATCH System Parts
After a Crash
{Warning
A crash can damage the LATCH system in

Warning (Continued)
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) 050 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)
050 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.
