What does a warning light with seat belt and a circle mean?

A warning light featuring a seat belt icon within a circle typically indicates that one or more seat belts in the vehicle are unfastened. This light serves as a reminder for all occupants to buckle up for safety. If the light remains illuminated while all seat belts are fastened, it may suggest a malfunction in the seat belt system, requiring further inspection. Always consult your vehicle's owner's manual for specific information related to warning lights.
