Toyota RUMION

The Toyota Rumion is a twin to the Maruti Suzuki Ertiga. From the Ertiga (July 2024—) owner's manual:
"2nd row passengers’ seat belt reminder (If equipped)
If the engine switch is pressed to change the ignition mode to “ON”, the seat belt reminder light comes on unless all 2nd row passengers’ seat belts are fastened, irre- spective of the presence or absence of passenger. The 2nd row passengers’ seat belt reminder works in the same manner as the driver’s seat belt reminder.
3rd row passengers’ seat belt reminder (If equipped)
If the engine switch is pressed to change the ignition mode to “ON”, the seat belt reminder light comes on unless all 3rd row passengers’ seat belts are fastened, irre- spective of the presence or absence of passenger. The 3rd row passengers’ seat belt reminder works in the same manner as the driver’s seat belt reminder."
