GMC Sierra 2500 HD 2024 Owner's Manual page 99

4. Push the latch plate into the buckle until
it clicks.
Position the release pushbutton on the
buckle, away from the child restraint, so
that the seat belt could be quickly
unbuckled if necessary.
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.
6. To tighten the belt, push down on the
child restraint, pull the shoulder portion
of the belt to tighten the lap portion of
the belt, and feed the shoulder belt back
into the retractor.
There must be finger clearance between
the release pushbutton and the child
restraint. If there is not clearance
between the buckle release pushbutton
and the child restraint, move the seat
upward and repeat prior installation
steps. Otherwise secure the child
restraint in a rear seat.
Seats and Restraints
When installing a forward-facing child
restraint, it may be helpful to use your
knee to push down on the child restraint
as you tighten the belt.
Try to pull the belt out of the retractor
to make sure the retractor is locked.
If the retractor is not locked, repeat
Steps 5 and 6.
7. If the vehicle does not have a rear seat
and the child restraint manufacturer
recommends using a top tether anchor,
attach the top tether to the top tether
anchor. Refer to the instructions that
came with the child restraint and to
Lower Anchors and Tethers for Children
(LATCH System) 0 81.
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.
