Ignition switch is ON.

The brake pedal is ON.

Vehicle speed is 4 km/h (2 MPH) or less.

Battery voltage is approximately 10 V or more.
CAUTION:
Run the engine when operating or inspecting the soft top to prevent battery dies.
CONDITIONS FOR STOPPING OPERATION
Operation of the soft top stops when the conditions below are satisfied while the soft top is operating.

Any of the above operation conditions is no longer satisfied.

The passenger side power seat is operated. (It does not move when seat cancel switch is ON.)
OUTLINE OF OPERATION
Refer to the illustrations for the positions of the soft top, and the conditions of switch and actuator operation.
OPERATION: FULL CLOSE → FULL OPEN
