SEATS
• Belts should fit snugly across the pelvis and chest.
Make sure any slack is wound up on the retractor.
To unfasten the belt:
Push in the release button on the buckle. The belt will
spring out of the buckle.
• To release a locked belt, lean back to take the body
pressure off of the belt.
• To store a lap-shoulder belt, allow the belt to wind up
on the retractor by guiding the belt tongue until the
belt comes to a stop.
Lap Belt
Proper Safety Belt Adjustment
Your combination lap-shoulder belt may need adjustment.
Adjust safety belts properly.
• The lap belt should be worn as low and tight on the
hips as possible. Make sure any slack is taken up by
the belt mechanism.
• The shoulder belt should fit snugly across your body.
It should be positioned midway over the shoulder
(nearer to the door); it should never rest against your
neck.
