Toyota Sienna. Active head restraints

When the occupant’s lower back presses against the seatback during a rear-end collision, the head restraint moves slightly forward and upward to help reduce the risk of whiplash on the seat occupant

Active head restraints

Even small forces applied to the seatback may cause the head restraint to move. When a locked head restraint is pushed up forcibly, the head restraint inner structure may appear. This does not indicate a problem.

WARNING

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

Be careful that the seat does not hit passengers or luggage.
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 reclined too far, 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.
Manual seat: After adjusting the seat, make sure that the seat is locked in position.
