Chevrolet Silverado 2015 Owner's Manual page 132

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 it
will 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.
Seats and Restraints
5. Pull the shoulder belt all the way
out 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.
