To Fold Down The Rear Seat
Locate the release lever (upper outboard side of seat), and
lift it upward until the seatback releases.
Slowly fold down the seatback.
To Raise The Rear Seat
Raise the seatback and lock it into place. If interference
from the cargo area prevents the seatback from fully
locking, you will have difficulty returning the seat to its
proper position.
NOTE: If the rear seatback is not fully latched, the center
shoulder belt will not be able to be extended for use. If
you cannot extend the center shoulder belt, make sure
your seatback is fully latched.
WARNING!
Be certain that the seatback is securely locked into
position. If the seatback in not securely locked into
position the seat will not provide the proper stability
for child seats and/or passengers. An improperly
latched seat could cause serious injury.
