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 50 for additional information.

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) 079 or

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, seeLower Anchors and
Tethers for Children (LATCH
System) 063 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) 063 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 062.
