112 Seats and Restraints
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) 0 93 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 0 137.
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.
I n f o r ma t i o n P r o v i d e d b y :
Tilt the latch plate to adjust the
belt, if needed.
4. Push the latch plate into the
buckle until it clicks.
