1. Pick up the latch plate and pull the belt
across you. Do not let it get twisted.
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.
2. Push the latch plate into the buckle until
it clicks.
Pull up on the latch plate to make sure
it is secure.
When the shoulder belt is pulled out all the
way, it will lock. If it does, let it go back all
the way and start again.
If the belt is not long enough, see Safety Belt
Extender on page 41.
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.
3. To make the lap part tight, pull up on the
shoulder part.
