In Hondas, the driver's seat belt
must be buckled for the engine to start. IIRC, the system is sophisticated enough that the belt must be re-buckled -- you can't just leave it buckled and tight to the seat back. IDK if you can just re-buckle it behind you every time?
There was an ongoing issue with CR-Vs, the seat belt return would pull the buckle up only part way. Then, when the driver shuts the driver's door, the buckle hits a sensor that gives you the "headlights are on" warning. Don't ask me how I know -- but Mr. Laughing had to come jump start the 2007 CR-V several times before we Googled the right words & replaced the sensor. This was a 5-speed, we also push-started her a couple times. A friend had a 2012 with the same sensor problem -- makes sense to me that our Kiely ended up with a dead battery at this party.
