CAUTION
To avoid serious personal injury, you must do the
following:
D When opening or closing the retractable hardtop,
make sure there is no person around there.
D When opening or closing the retractable hardtop,
keep hands away from the hinges of the hardtop side
rails and any part of the hardtop linkage mechanism.
D Do not stop operating the switch in the middle of
operation unless otherwise required. The roof will be
gradually lowered, resulting in personal injury and
damage to the hardtop mechanism.
D Do not open or close the retractable hardtop when
the wind is strong.
D The vehicle should never be driven with the
retractable hardtop partially opened. Make sure the
hardtop has been either fully opened or fully closed
before driving.
D While the vehicle is moving with the retractable
hardtop opened, nobody should stand up on the seat,
sit on the package tray or lean over it. Otherwise, they
could be seriously injured if the vehicle stops
suddenly or if the vehicle is involved in an accident.
