CAUTION
■While driving
●Do not adjust the position of the driver’s seat.
Doing so could cause the driver to lose control of the vehicle.
●Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the
effectiveness of the seat belt and head restraint, increasing the risk of death or
serious injury to the driver or passenger.
●Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the seat tracks and
stop the seat from locking in place. This may lead to an accident. The adjustment
mechanism may also be damaged.
■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.

CAUTION
■Child restraint precautions
●Do not use the seat belt extender when installing a child restraint system on the
front or rear passenger seat. If installing a child restraint system with the seat belt
extender connected to the seat belt, the seat belt will not securely hold the child
restraint system, which could cause death or serious injury to the child or other
passengers in the event of a sudden stop, sudden swerve or accident.
●Do not allow the child to lean his/her head or any part of his/her body against the
door or the area of the seat, front pillar or roof side rail from which the side air-
bags or curtain shield airbags deploy even if the child is seated in the child
restraint system. It is dangerous if the side airbags and curtain shield airbags
inflate, and the impact could cause death or serious injury to the child.
●Make sure you have complied with all installation instructions provided by the
child restraint manufacturer and that the system is properly secured. If it is not
secured properly, it may cause death or serious injury to the child in the event of a
sudden stop, sudden swerve or an accident.
■Child restraint lock function belt precaution
Do not allow children to play with the child restraint lock function belt. If the belt
becomes twisted around a child’s neck, it will not be possible to pull the belt out
leading to choking or other serious injuries that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used to cut
the belt.
■When the child restraint system is not in use
●Keep the child restraint system properly secured on the seat even if it is not in use.
Do not store the restraint unsecured in the passenger compartment.
●If it is necessary to detach the child restraint system, remove it from the vehicle or
store it securely in the trunk. This will prevent it from injuring passengers in the
event of a sudden stop, sudden swerve or accident.
