■Power easy access system (if equipped)
The driver’s seat and steering wheel move in
accordance with engine switch mode and
the driver’s seat belt condition. ( P. 1 2 6 )
■When adjusting the seat
●Take care when adjusting the seat so that the head restraint does not touch the ceiling.
●When folding down a rear seatback, if it inte rferes with a front seatback, adjust the front
seat position so that the seats no longer interfere with each other. However, if adjusting
the front seat position causes the correct driving posture to not be maintained, return
the rear seatback to its original position. ( P. 1 2 4 )

CAUTION
■When adjusting the seat position
●Take care when adjusting the seat position to ensure that other passengers are not
injured by the moving seat.
●Do not put your hands under the seat or near the moving parts to avoid injury.
Fingers or hands may become jammed in the se
at mechanism.
●Make sure to leave enough space around the feet so they do not get stuck.
■Seat adjustment
To reduce the risk of sliding under the lap belt during a collision, do not recline the seat
more than necessary.
If the seat is too rec lined, the lap belt may slide past the hips and apply restraint forces
directly to the abdomen, or your neck may contact the shoulder belt, increasing the risk
of death or serious injury in the event of an accident.
Adjustments should not be ma de while driving as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.
