(b) Driver’s Seat Belt Reminder Light and Buzzer
The light and buzzer act as a reminder to buckle up the driver’s
seat belt.
Once the ignition key is turned to the “ON” position, the buzzer
sounds for about 6 seconds and the reminder light flashes if the
driver’s seat belt is not fastened. Unless the driver fastens the
belt, the light continues flashing.
If the vehicle speed rises above 15 km/h (9 mph) with the seat
belt unfastened, the buzzer will sound for about 10 seconds.
Then, if the seat belt is still unfastened, the buzzer will sound
in a different tone for 20 more seconds. Even if the vehicle
speed drops below 15 km/h (9 mph), the buzzer will continue
to sound. To stop the buzzer, fasten the seat belt.

and Buzzer
The light and buzzer act as a reminder to have the front
passenger buckle up the seat belt.

reminder light flashes if a passenger sits in the front passenger
seat and does not fasten the seat belt. Unless the front
passenger fastens the belt, the light continues flashing.

belt unfastened, the buzzer will sound for about 10 seconds.
