3-46 Seats and Restraints
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.
If the child restraint does not have
the LATCH system, you will be
using the safety belt to secure the
child restraint in this position.
Be sure to follow the instructions
that came with the child restraint.
Secure the child in the child restraint
when and as the instructions say.
If more than one child restraint
needs to be installed in the rear
seat, be sure to read Where to Put
the Restraint on page 3 38.
1. Put the child restraint on
the seat.
2. Pick up the latch plate, and run
the lap and shoulder portions of
the vehicle safety belt through or
around the restraint. The child
restraint instructions will show
you how.
3. Push the latch plate into the
buckle until it clicks.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
