04 06.30 GAUGES, METERS AND SERVICE REMINDER INDICATORS (b) Driver's Seat Belt Reminder Light and Buzzer The light and buzzer acts as a reminder to buckle up the driver's seat belt. Once the ignition key is turned to "ON" or "START", the reminder light flashes and buzzer sounds if the driver's seat belt is not fastened. Unless the driver fastens the belt, the light continues flashing and the buzzer stops after about 4 to 8 seconds. (d) SRS Warning Light The indicator comes on when the ignition key is turned to the "ACC" or "ON" position. It goes off after about 6 seconds. This means the SRS airbags and front seat belt pretensioners are operating properly. The SRS warning light system monitors the airbag sensor assembly, front airbag sensors, side and curtain shield airbag sensors, front seat belt pretensioner assemblies, inflators, warning light, interconnecting wiring and power sources. If either of the following conditions occurs, this indicates a malfunction somewhere in the components monitored by the warning light system. Contact your Lexus dealer as soon as possible to service the vehicle. D The light does not come on when the ignition key is turned to the "ACC" or "ON" position or remains on for more than 6 seconds or flashes. D The light comes on or flashes while driving. If the light stays on, it indicates that the driver and front passenger airbags fail. If the light flashes, the side and curtain shield airbags and/or seat belt pretensioners fail. (c) Front Passenger's Seat Belt Reminder Light The light acts as a reminder to have the front passenger buckle up the seat belt. Once the ignition key is turned to "ON" or "START", 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 stays flashing. However, if a front passenger uses an additional seat cushion, the light may not flash even when the seat belt is not buckled up. 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. 51
