Children (LATCH System) 0 74.
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 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.
To remove the child restraint, unbuckle the
vehicle seat belt and let it return to the
stowed position. If the top tether is attached
to a top tether anchor, disconnect it.
Reinstall the head restraint or headrest
before the seating position is used. See
Head Restraint or Headrest Removal and
Reinstallation under Lower Anchors and
Tethers for Children (LATCH System) 0 74 for
additional information on installing the
headrest properly.

1. Put the child restraint on the seat.
2. 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.
3. Push the latch plate into the buckle until
it clicks.
Position the release button on the
buckle, away from the child restraint, so
that the seat belt could be quickly
unbuckled if necessary.
4. 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.
