1. Pull up on the seatback release lever while pulling
the seatback toward the rear of the vehicle.
2. After the lever has been released, push the
seatback toward the front of the vehicle until it locks
into place.

located on the right rear of
the second row seat.
To raise the seatback, do the following:
1. Unlock the seatback lever by pulling up on the
lever while pushing down on the upper edge of
the seatback.
2. Move the seatback into the upright position.
3. Make sure the seatback is locked when it is back
in the upright position.
CAUTION:
{
If the seatback is not locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
press rearward on the seatback to be sure it
is locked.
