A warning tone sounds if you do not fasten your seatbelt when you switch the power on. The tone switches off when you fasten your seatbelt or about one minute elapses.
When the initial warning expires for the driver, more warnings are provided for the driver and front passenger. This warning tone sounds if you or your front passenger do not fasten the seatbelt buckle and the vehicle speed exceeds 6 mph (9.7 km/h).
This tone also sounds if an occupant unfastens the rear seatbelt buckle or it becomes unfastened.
