If the belt stops before it reaches
the buckle, for lap shoulder belts
with cinching latch plates, tilt
the latch plate and keep pulling
the safety belt until it can be
buckled.
3. Push the latch plate into the
buckle until it clicks. If you find
that the latch plate will not go
fully into the buckle, see if you
are using the correct buckle.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Safety
Belt Extender on page 3 28.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.

up on the shoulder belt.
It may be necessary to pull
stitching on the safety belt
through the latch plate to fully
tighten the lap belt on smaller
occupants.
