Folding the rear seat
The rear seatbacks can be folded to facilitate carrying long items or to increase
the luggage capacity of the vehicle.
WARNING
Never allow passengers to sit on top of the folded down seatback while
the vehicle is moving. This is not a proper seating position and no seat belts
are available for use. This could result in serious injury or death in case
of an accident or sudden stop.
Objects carried on the folded down seatback should not extend higher
than the top of the front seatbacks. This could allow cargo to slide forward
and cause injury or damage during sudden stops.
