SEAT BELT: SEAT BELT WARNING SYSTEM (w/ Occupant Classification System): 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 seat belt warning light:

When the driver seat belt is not fastened with the ignition switch ON, the driver seat belt warning light on the combination meter comes on to inform the driver. The main body ECU detects the driver seat belt status and sends signals to the combination meter using BEAN.

(b) Front passenger seat belt warning light:

When the passenger seat belt is not fastened with the ignition switch ON and the passenger seat occupied, the seat belt warning light of the front passenger seat belt warning light blinks. The combination meter displays the passenger seat belt status and whether the passenger seat is occupied.

(c) Seat belt warning buzzer:

When the vehicle is driven at approximately 25 km/h (16 mph) or more while the driver or front passenger seat belt is not being fastened, the seat belt warning buzzer in the combination meter sounds at an interval of 1.2 seconds for 30 seconds.
