■When adjusting the seat position
● Take care when adjusting the seat position to ensure that other passen-
gers are not injured by the moving seat.
● Do not put your hands under the seat or near the moving parts t o 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 colli sion, do not
recline the seat more than necessary.
If the seat is too reclined, the lap belt may slide past the hi ps and apply
restraint forces directly to the abdomen, or your neck may cont act the
shoulder belt, increasing the risk of death or serious injury i n the event of
an accident.
Adjustments should not be made while driving as the seat may un expect-
edly move and cause the driver to lose control of the vehicle.
● After adjusting the seat, make sure that the seat is locked in position.
