If power operation is not available, the back door can be operated manually. Power operation may not be available if the 12-volt battery voltage is low or if the back door is open approximately 150 mm (5.9 in) or less from the fully closed position. When the power back door is turned off, the back door can be opened manually by pushing the back door opener switch. If the power back door opener switch is pushed during power open or close, the power operation will be cancelled and the back door can be operated manually. This will allow normal power operation functions to resume.
