Lap-Shoulder Belt
All rear seating positions have lap-shoulder belts.
Here is how to wear one properly.
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.
If the belt stops before it reaches the buckle,
tilt the latch plate and keep pulling until you can
buckle it.
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.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, see Safety Belt
Extender on page 1-30.
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.
