Child Restraint
3. To get the retractor into the automatic
locking mode, pull the shoulder belt
portion of the seat belt until the entire
length of the belt is out of the retractor.
4. Push the child-restraint system firmly
into the vehicle seat. Be sure the belt
retracts as snugly as possible. A
clicking noise from the retractor will be
heard during retraction if the system is
in the automatic locking mode. If the
belt does not lock the seat down tight,
repeat this step.

NOTE
Inspect this function before each use of the
child-restraint system. You should not be able
to pull the shoulder belt out of the retractor
while the system is in the automatic locking
mode. When you remove the child-restraint
system, be sure the belt fully retracts to return
the system to emergency locking mode before
occupants use the seat belts.
5. If your child-restraint system requires
the use of a tether strap, refer to the
manufacturer's instructions to hook and
tighten the tether strap (except center
position).
