Split-Folding Rear Seat
452
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
passenger. The person sitting in that
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.
To reinstall the rear seat cushion, do the following:
1. Position the seat cushion so that you can
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.
