How to sound a car seat belt warning

The warning that sounded when you didn’t fasten your seat belt was when the weight of the chair was recognized.

I thought it would ring if I opened and closed the door, wore a belt, and unfastened it.

I bought a pig’s feet bossam set and put it in the passenger seat.

The car started and the alarm went off right away.go

There’s no sound when I put it under the set chair.

I’m the only one who didn’t know this.
