3. Insert the belt tongue into the buckle on the inboard side
of the seat.
4. Push down until the tongue locks securely (with an audible
click). Pull on the belt to check for proper fastening.
• Pull the shoulder section to make sure the belt fits
snugly across the chest.
• The shoulder belt must be positioned over the shoulder—it
must never rest against the neck.
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.
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.
