If the webbing locks in the latch
plate before it reaches the
buckle, tilt the latch plate flat to
unlock.
4. 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 seat belt
could be quickly unbuckled if
necessary.
5. 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.
SEATS AND RESTRAINTS
6. To make the lap part tight, pull
up on the shoulder belt.
To unlatch the belt, push the button
on the buckle. The belt should return
to its stowed position.
Always stow the seat belt slowly. If the
seat belt webbing returns quickly to
the stowed position, the retractor may
lock and cannot be pulled out. If this
happens, pull the seat belt straight out
firmly to unlock the webbing, and
then release it. If the webbing is still
locked in the retractor, see your
dealer.
