Note: The automatic locking mode is available on the front passenger
and rear seats. This vehicle does not require the use of a locking clip.
6. Allow the belt to retract to remove slack. The belt will click as it
retracts to indicate it is in the automatic locking mode.
7. Try to pull the belt out of the retractor to make sure the retractor is
in the automatic locking mode. You should not be able to pull more belt
out. If the retractor is not locked, unbuckle the belt and repeat Steps 5
and 6.
This is necessary to remove the remaining slack that will exist once the
additional weight of the child is added to the child restraint. It also helps
to achieve the proper snugness of the child seat to the vehicle.
Sometimes, a slight lean towards the buckle will additionally help to
remove remaining slack from the belt.
9. Attach the tether strap (if the child seat is equipped). Refer to Using
tether straps later in this chapter.

automatic locking mode, grasp the
shoulder portion of the belt and pull
downward until all of the belt is
pulled out.
8. Remove remaining slack from the
belt. Force the seat down with extra
weight, e.g., by pressing down or
kneeling on the child restraint while
pulling up on the shoulder belt in
order to force slack from the belt.
