■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.
CAUTION
■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 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 unexpect-
edly 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.
