SEAT BELT WARNING 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, gear position*1, shift lever position*2 and parking brake state.
  - *1: for Manual Transaxle
  - *2: except Manual Transaxle
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, gear position*1, shift lever position*2 and parking brake state.
  - *1: for Manual Transaxle
  - *2: except Manual Transaxle
3. Seat belt warning buzzer:
  After turning the ignition switch to ON, if the driver seat belt is not fastened within 1.8 seconds, check that the seat belt warning buzzer in the combination meter assembly sounds at 1.2 seconds intervals for 6 seconds.
  
  When the vehicle is driven at 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 sounds once.
  
  When 30 seconds have passed after the buzzer sounded, the seat belt warning buzzer in the combination meter assembly sounds at an interval of 1.2 seconds for 9.6 seconds.
  
  After that, the seat belt warning buzzer in the combination meter assembly sounds at an interval of 0.4 seconds for 20 seconds.

FUNCTION OF MAIN COMPONENTS

Component	Function
Front seat inner belt assembly LH	Informs the airbag sensor assembly of the driver seat belt condition (fastened or unfastened).
Front seat inner belt assembly RH	Informs the occupant detection ECU of the front passenger seat belt condition (fastened or unfastened).
Occupant classification sensor LH Occupant classification sensor RH	Informs the occupant detection ECU of the front passenger seat condition (occupied or unoccupied).
Combination meter assembly	The combination meter assembly illuminates, blinks or turns off the seat belt warning light. The combination meter assembly sounds the seat belt warning buzzer.
Occupant detection ECU	Sends the front passenger seat belt buckle switch signal and occupant detection signal to the airbag sensor assembly.
Airbag sensor assembly	Sends the driver seat belt buckle switch signal to the main body ECU (multiplex network body ECU) via CAN communication. Sends the front passenger seat belt buckle switch signal to the combination meter assembly via CAN communication.
Main body ECU (Multiplex network body ECU)	Sends the driver seat belt buckle switch signal and parking brake switch signal to the combination meter assembly via CAN communication.
Skid control ECU (Brake actuator assembly)	Sends the vehicle speed signal to the combination meter assembly via CAN communication.
ECM	Sends the gear position1 or shift position2 signal to the combination meter assembly via CAN communication.

*1: for Manual Transaxle
*2: except Manual Transaxle
