Proposal to introduce a new paragraph 0.4 clarifying that second-level warnings apply when one seat-belt is unfastened during normal driving, excluding situations of higher priority warnings such as door opening or thermal propagation, to amend the definition of “normal operation” to specify forward motion above 10 km/h without other safety warnings triggered, and modify paragraph 5.2.4.3 to allow discontinuation of second-level warnings when other audible safety warnings are triggered in circumstances of imminent danger.
