SYSTEM DESCRIPTION
1. SEAT BELT WARNING SYSTEM DESCRIPTION
If a seat belt is not fastened, this system flashes the seat belt warning light or sounds the seat belt warning buzzer as a reminder.
(a) Driver side seat belt warning light:
When the driver side seat belt is not fastened with the ignition switch ON, the driver side seat belt warning light on the combination meter assembly blinks to inform the driver. The center airbag sensor assembly detects the driver side seat belt status and sends signals to the combination meter assembly via CAN communication.
(b) Front passenger side seat belt warning light:
When the front passenger side seat belt is not fastened with the ignition switch ON and the front passenger seat occupied, check that the front passenger side seat belt warning light on the accessory meter assembly blinks. The accessory meter assembly displays the front passenger side seat belt status and whether the front passenger side seat is occupied.
(c) Seat belt warning buzzer:
When the vehicle is driven at approximately 20 km/h (13 mph) or more while the driver or front passenger side seat belt is not fastened, 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 buzzer sounds at an interval of 0.4 seconds for 20 seconds.
