■After returning the rear seatbacks or installing seats
Observe the following precautions. Failure to do so may result in death or
serious injury.
● Make sure the seatback is securely locked by pushing it forward and rear-
ward on the top.
● Check that the seat belts are not twisted or caught in the seatback.
● Make sure the seat is locked in place by trying to shake the seatback and
lift up the seat cushion.
■ Removing the second seats
●Do not leave a seat in the vehicle if it has been disengaged from the floor.
● Do not sit on or place anything on a seat that has been removed from the\
vehicle.
■ Stowing the third seats
●Make sure that the seat path is clear before moving the seat. Otherwise,
injury may result from contact with, or by being pinched by parts of the
seat.
● Manual third seats: Do not sit on the third seat when it is in the stowed
position with the seatback upright.
● Power third seats: Do not continue the stowing operation when the indica-
tor above the stowing switch and returning switch comes on or flashes. An
object or a person may be caught in the seat.
● Power third seats: During the stowing operation, to prevent the vehicle
from moving, do not shift the shift lever out of P with the engine switch in

CAUTION
■When adjusting the seat position or the ottoman (vehicles with Otto-
man seats)
Make sure to leave enough space around the feet so as not to get them
caught.
■ When using the ottoman (vehicles with Ottoman seats)
●Do not sit on the ottoman. Seat belts may not be properly worn which may
result in death or serious injury.
● Stow the ottoman when you get in and out of the vehicle or when the otto-
man is not in use to avoid stumbling over it.
● Do not use the ottoman feature when the vehicle is in motion. The ottoman
feature should only be used when the vehicle is stationary. If the ottoman
feature is in use during an accident the lap belt may slide past the hips.
This could also result in restraint forces being applied to the abdomen or
your neck may contact the shoulder belt, increasing the risk of death or
serious injury.
NOTICE
■To prevent damage to the seat
●Avoid putting heavy loads on a folded seat that is being used as a tempo-
rary table.
● Do not sit on or put heavy loads on a second seat that has been removed
from the vehicle. The metal tips of the seat leg may be damaged, prevent-
ing reinstallation of the seat.
● The second seats must be reinstalled in their original positions. If they are
installed in the wrong position, the seat locks or bezels will be damaged.
● Make sure that the path the seat will move through is clear before stowing
or returning the third seat.
● 8-passenger models: Be sure to raise the stowed second center seat
above the outer trim, when removing from the storage box of the luggage
room.
