7. For forward-facing child
restraints, attach and tighten
the top tether to the top tether
anchor (loop). Refer to the child
restraint instructions, the
vehicle LATCH anchor weight
limits and instructions listed in
Lower Anchors and Tethers for
Children (LATCH System) 0 94.
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 safety 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 safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it.
Reinstall the headrest before the
seating position is used. See
Headrest Removal and
Reinstallation under Lower Anchors
and Tethers for Children (LATCH
System) 0 94 for additional
information on installing the
headrest properly.

lock is set, the belt can be
tightened but not pulled out of
