raise the seatback to the
upright position using the strap
on the back of the third row
seat, or lift the seatback and
push it into place from inside
the vehicle.

If either seatback is not locked, it
could move forward in a sudden
stop or crash. That could cause
injury to the person sitting there.

Seats and Restraints
Warning
A seat belt that is improperly
routed, not properly attached,
or twisted will not provide the
protection needed in a crash. The
person wearing the belt could be
seriously injured. After raising the
rear seatback, always check to be
sure that the seat belts are
properly routed and attached, and
are not twisted.
