Front seat
If the vehicle speed exceeds about 20 km/h (12 mph) with the driver or front passenger's seat belt unfastened, a warning beep sounds continuously. If the seat belt remains unfastened, the beep sound stops once and then continues for about 90 seconds. The beep stops after the driver or front passenger's seat belt is fastened.
Placing heavy items on the front passenger seat may cause the front passenger seat belt warning function to operate depending on the weight of the item.
To allow the front passenger seat weight sensor to function properly, do not place and sit on an additional seat cushion on the front passenger seat. The sensor may not function properly because the additional seat cushion could cause sensor interference.
When a small child sits on the front passenger seat, it is possible that the warning beep will not operate.
Rear seat
The warning beep only sounds if a seat belt is unfastened after being fastened.
