The sound comes from the seatbelt reminder system used in Mazda vehicles, where an electronic chime warns the driver and passengers to fasten their belts. This v2 recording is noted as higher pitched than the standard version, which helped it stand out when shared on soundboards. Car enthusiasts and editors began using short dashboard tones like this outside the car as instant alert signals, and the Mazda chime remains popular because it is recognisable, brief, and easy to drop into videos, streams, and group chats.
