out of the retractor to set the lock.
5. 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. If you are
using a forward-facing child restraint, you may
find it helpful to use your knee to push down on
the child restraint as you tighten the belt.
6. If your child restraint manufacturer
recommends using a top tether, attach and
tighten the top tether to the top tether anchor.
Refer to the instructions that came with the
child restraint and see Lower Anchors
and Tethers for Children (LATCH) on page 53.
