door is about to open or close.

door is operating automatically, the automatic operation is stopped. The back
door then has to be operated manually. Take extra care when on an incline, as the
back door may open or close unexpectedly.

may sound and the back door may stop opening or closing. The back door then
has to be operated manually. Take extra care when on an incline, as the back door
may open or close abruptly.
