SEATS AND RESTRAINTS 75
{Warning
A child in a rear-facing child
restraint can be seriously injured or
killed if the front outboard
passenger frontal 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 front outboard
passenger frontal airbag inflates
and the passenger seat is in a
forward position.
Even if the passenger sensing
system has turned off the front
outboard passenger airbag(s), no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though the
airbag(s) are off.
Secure rear-facing child restraints
in a rear seat, even if the airbag(s)
are off. If you secure a
forward-facing child restraint in the(Continued)
Warning (Continued)
front outboard passenger seat,
always move the seat as far back as
it will go. It is better to secure the
child restraint in a rear seat.
SeePassenger Sensing System 053
for additional information.
If the child restraint uses a top tether,
see Lower Anchors and Tethers for
Children (LATCH System) 065 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. 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. Move
the seat upward or the seatback to
an upright position, if needed, to
get a tight installation of the child
restraint.
When the passenger sensing
system has turned off the front
outboard passenger frontal airbag
and knee airbag, the OFF indicator
on the passenger airbag status
indicator should light and stay lit
when you start the vehicle. See
Passenger Airbag Status Indicator
096.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder portions of the
vehicle seat belt through or around
the child restraint. The child
restraint instructions will show
you how.

7. Before placing a child in the childrestraint, make sure it is securely
held in place. To check, grasp the
child restraint at the seat 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.
If the airbags are off, the OFF
indicator in the passenger airbag
status indicator will come on and stay
on when the vehicle is started.
If a child restraint has been installed
and the ON indicator is lit, see “If the
On Indicator Is Lit for a Child
Restraint ”under Passenger Sensing
System 053.
To remove the child restraint,
unbuckle the vehicle seat belt and let
it return to the stowed position.
