Power easy access system (if equipped)
The driver’s seat and steering wheel move in accordance with power switch
mode and the driver’s seat belt condition. (P. 170)
When adjusting the seat
If the head restraint touches the ceiling or rear seats while the seat is being
adjusted, lower the head restraint until it no longer touches the ceiling or rear
seats.
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 seat 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 reclined, 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 made while driving as the seat may unexpectedly
move and cause the driver to lose control of the vehicle.
