Driver Position
This part describes the driver's restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here's how to wear it
properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight. To see
how, see "Seats" in the Index.
3. Pick up the latch plate and pull the belt across you.
Don't 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.
4. Push the latch plate into the buckle until it clicks.
Pull up on the latch plate to make sure it is
secure. If the belt isn't 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.
