Warning (Continued)
passenger frontal airbag could
inflate even though the airbag
on-off switch is turned off.
To help avoid injury to yourself or
others, have the vehicle serviced
right away. SeeAirbag Readiness
Light on page 5-18 for more
information, including important
safety information.
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.
If a child restraint uses a top tether,
see Lower Anchors and Tethers for
Children (LATCH System) on
page 3-44 for top tether anchor
locations.
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 anchored, or if
the instructions that come with the
child restraint say that the top strap
must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached.
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. Move the seat as far back as it
will go before securing the
forward-facing child restraint.
When the airbag off switch (if
equipped) has turned off the
front outboard passenger frontal
airbag, the off indicator in the
airbag off light should light and
stay lit when you start the
vehicle. See Airbag On-Off Light
on page 5-18.
2. Put the child restraint on the seat. 3. Pick up the latch plate, and run
the lap and shoulder portions of
the vehicle's safety belt through
or around the restraint. The child
restraint instructions will show
you how.
Tilt the latch plate to adjust the
belt, if needed.

3-68 Seats and Restraints
7. If your vehicle does not have arear seat and your child restraint
has a top tether, follow the child
restraint manufacturer's
instructions regarding the use of
the top tether. See Lower
Anchors and Tethers for
Children (LATCH System) on
page 3-44.
8. Before placing a child in the child restraint, make sure it is
securely held in place. To check,
grasp the child restraint at the
safety belt path and attempt to
move it side to side and back
and forth. When the child
restraint is properly installed,
there should be no more than
2.5 cm (1 in) of movement.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it. If you turned the airbag off with the
switch (if equipped), turn on the
front outboard passenger airbag
when you remove the child restraint
from the vehicle unless the person
who will be sitting there is a member
of a passenger airbag risk group.
See
Airbag On-Off Switch on
page 3-27 for more information,
including important safety
information.
Heavy-Duty Crew Cab Only
This vehicle has airbags. A rear
seat is a safer place to secure a
forward-facing child restraint. See
Where to Put the Restraint on
page 3-43.
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.
{Warning
A child in a rear-facing child
restraint can be seriously injured
or killed if the front outboard
passenger airbag inflates. This is
because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. Always secure a
rear-facing child restraint in a
rear seat.
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.
If a child restraint uses a top tether,
see Lower Anchors and Tethers for
Children (LATCH System) on
page 3-44 for top tether anchor
locations.

Seats and Restraints 3-69
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 strap
must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether be
attached.
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. Move the seat as far back as itwill go before securing the
forward-facing child restraint.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder portions of
the vehicle's safety belt through or around the restraint. The child
restraint instructions will show
you how.
4. Push the latch plate into the
buckle until it clicks.
Make sure the release button is
positioned so you would be able
to unbuckle the safety belt
quickly if necessary.
5. Pull the shoulder belt all the wayout of the retractor to set the
lock. When the retractor lock is
set, the belt can be tightened but
not pulled out of the retractor.

6. To tighten the belt, push downon the child restraint, pull the
shoulder portion of the belt to
tighten the lap portion of the belt,
and feed the shoulder belt back
into the retractor. When installing
a forward-facing child restraint, it
may be helpful to use your knee
to push down on the child
restraint as you tighten the belt.
Try to pull the belt out of the
retractor to make sure the
retractor is locked. If the
retractor is not locked, repeat
Steps 5 and 6. 7. If your child restraint has a top
tether, follow the child restraint
manufacturer's instructions
regarding the use of the top
tether. See Lower Anchors and
Tethers for Children (LATCH
System) on page 3-44 for more
information on using the top
tether anchors.
