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.
Until a seat belt is fastened or a given
period of time has elapsed, the beep
sound will not stop even if the vehicle
speed falls below 20 km/h (12 mph).
NOTE
Placing heavy items on the front
passenger's seat may cause the front
passenger's 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's
seat. The sensor may not function
properly because the additional seat
cushion could cause sensor

If a small child is seated on the front
passenger's seat, the warning beep
may not operate.

The warning beep only sounds if a seat
belt is unfastened after being fastened.
