NOTE: Prior to rotating the seat cushions rearward, be
sure that the rear seat belt buckles are secured with the
straps, so that the buckles are accessible.
3. Rotate the seat cushion rearward to latch the seat.
Then lift the seatback to its upright latched position.
NOTE: Prior to lifting either seatback to the upright
position, be sure that the seat belt is brought forward to
avoid trapping it behind the seatback.
CAUTION!
Ensure that the seat back is latched with a hard push
to engage the latch, noting the presence of seat back
rubber-overslam bumpers that need to be overcome.
Check that the seat back release knobs are pushed
fully forward in order to allow the latch to engage.
WARNING!
In an accident, you or others in your vehicle could be
injured if seats are not properly latched to their
attachments. Always be sure the seats are fully
latched.
