{CAUTION:
A safety belt that is not properly routed
through the seat cushion or is twisted will
not provide the protection needed in a
crash. If the safety belt has not been
routed through the seat cushion at all, it
will not be there to work for the next

position could be badly injured. After
reinstalling the seat cushion, always
check to be sure that the safety belts are
properly routed and are not twisted.

route the safety belts through the proper
slots in the seat cushion.
2. Slide the rear of the cushion up and under the
seatback so the rear-locating guides hook into
the wire loops on the back frame.
