Adjusting The Rear Center Facing Jump Seat Lap Belt - Mazda B4000 Owner's Manual

WARNING: The lap belts should fit snugly and as low as
possible around the hips, not around the waist. Failure to
position the lap belt correctly may cause serious injury in an
accident.
Insert the tongue into the correct
buckle (the buckle closest to the
direction the tongue is coming
from). To lengthen the belt, turn the
tongue at a right angle to the belt
and pull across your lap until it
reaches the buckle.
To tighten the belt, pull the loose
end of the belt through the tongue
until it fits snugly across the hips.
Shorten and fasten the belt when not in use to keep the belt
away from door openings and available after unfolding the seats.
Adjusting the rear center facing jump seat lap belt (if equipped)
The center facing rear jump seat lap belt will adjust automatically. To
fasten, grasp the tongue, and with a continuous motion, pull out enough
webbing to buckle the tongue into the correct buckle. If you did not pull
out enough webbing to reach the buckle, allow the tongue to retract fully
before trying to pull it out again.
WARNING: The lap belts should fit snugly and as low as
possible around the hips, not around the waist. Failure to
position the lap belt correctly may cause serious injury in an
accident.
