GAUGES, METERS AND SERVICE REMINDER INDICATORS (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. If luggage or other load is placed on the front passenger seat, depending on its weight and how it is placed on the seat, built−in sensors in the seat cushion may detect the pressure, causing the reminder light to flash and buzzer to sound. (d) SRS Warning Light The indicator comes on when the ignition key is turned to the "ON" position. It goes off after about 6 seconds. This means the SRS airbags and front seat belt pretensioners are operating properly. This warning light system monitors the airbag sensor assembly, front airbag sensors, side and curtain shield airbag sensor assemblies, curtain shield airbag sensor assemblies, driver's seat position sensor, driver's seat belt buckle switch, front passenger occupant classification system, "AIRBAG ON" indicator light, "AIRBAG OFF" indicator light, front passenger's seat belt buckle switch, front seat belt pretensioner assemblies, inflators, warning light, interconnecting wiring and power sources. (c) Front Passenger's Seat Belt Reminder Light and Buzzer The light and buzzer act as a reminder to have the front passenger buckle up the seat belt. Once the ignition key is turned to the "ON" position, the 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. 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. 90
