4-Door Utility
1. Pick up the latch plate and pull the belt across you.
2. Push the latch plate into the buckle until it clicks.
Don't let it get twisted.
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" 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.
