3. Pick up the latch plate and pull the belt across you.
Don't let it get twisted.
On convertible models, the 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.
4. Push the latch plate into the buckle until it clicks.
If the belt stops before it reaches the buckle, tilt the
latch plate and keep pulling until you can buckle
the belt.
Pull up on the latch plate to make sure it is secure.
If the belt isn't long enough, see "Safety Belt
Extender" at the end of this section.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if you ever had to.
