securely held in place. To
check, grasp the child restraint
at the LATCH path and attempt
to move it side to side and

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

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.
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.
(Continued)
Warning (Continued)
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
0 65 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.

lower inboard side of the
cab wall directly behind
the front passenger seat.

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) 079 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) 079 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 077.

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

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
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.
A booster seat may be used in the
left rear seating position if the base
of the booster seat fits on the seat
cushion and does not extend past
the front edge of the seat cushion. If the booster seat extends past the
front of the seat cushion, it should
be used in the right rear seating
position with the seat cushion
extension.
When using the lap-shoulder belt to
secure the child restraint in this
position, follow the instructions that
came with the child restraint and the
following instructions:
1. Always install the seat cushion extension in the right rear seat
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.
