SEAT BELT WARNING SYSTEM(w/ Occupant Classification System) SYSTEM DESCRIPTION

SEAT BELT WARNING SYSTEM (w/ Occupant Classification System) DESCRIPTION
1. Seat belt warning light operation for driver seat belt:
  
  The seat belt warning light on the combination meter assembly illuminates, blinks or turns off in accordance with the driver seat belt state, vehicle speed, shift lever position and parking brake state.
2. Seat belt warning light operation for front passenger seat belt:
  
  The seat belt warning light on the combination meter assembly illuminates, blinks or turns off in accordance with whether the front passenger seat is occupied, the front passenger seat belt state, vehicle speed, shift lever position and parking brake state.
3. Rear seat belt warning light:
  
  The rear seat belt warning light on the telltale light assembly illuminates, blinks or turns off in accordance with the rear door state, vehicle speed and rear seat belt state.
4. Front seat belt warning buzzer:
  
  When the vehicle is driven at approximately 20 km/h (12 mph) or more with the front passenger seat occupied and the driver or front passenger seat belt not fastened, the seat belt warning buzzer in the combination meter assembly will sound at an interval of 1.2 seconds for 30 seconds.
  
  After that, the seat belt warning buzzer in the combination meter assembly will sound at an interval of 0.4 seconds for 90 seconds.
5. Rear seat belt warning buzzer:
  
  When the vehicle is driven at approximately 20 km/h (12 mph) or more with a rear seat belt not fastened, the seat belt warning buzzer in the combination meter assembly will sound once, and then sound at an interval of 1.2 seconds for 6 seconds.
  
  After that, the seat belt warning buzzer in the combination meter assembly will sound at an interval of 0.4 seconds for 30 seconds.
