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
To reduce the risk of sliding under the lap be lt 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 shou lder belt, increasing the risk
of death or serious injury in the event of an accident.
Adjustments should not be made while drivin g as the seat may unexpectedly move and
cause the driver to lose control of the vehicle.
