66 SEATS AND RESTRAINTS
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.
If the shoulder portion of a
passenger belt is pulled out all
the way, the child restraint
locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.
If the webbing locks in the latch
plate before it reaches the
buckle, tilt the latch plate flat to
unlock.
3. Push the latch plate into the
buckle until it clicks.
Pull up on the latch plate to
make sure it is secure.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
4. If equipped with a shoulder belt
height adjuster, move it to the
height that is right for you. See
Shoulder Belt Height Adjuster
later in this section for use and
important safety information.
5. To make the lap part tight, pull
up on the shoulder belt.
