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.

period of time has elapsed, the beep
sound will not stop even if the vehicle
speed falls below 20 km/h (12 mph).

passenger's seat may cause the front
passenger's seat belt warning
function to operate depending on
the weight of the item.
