The sensor works based on pressure, but it is an electronic device.

Now that I think about it, I'll test this hypothesis on the way home, see if airplane mode still triggers it.

Electrical signals from a phone or other electronic device give a false positive on the capacitive load sensor in the seats of the Toyobaru.
