GAUGES, METERS AND SERVICE REMINDER INDICATORS (b) Driver's Seat Belt Reminder Light and Buzzer This light and buzzer remind you to buckle up the driver's seat belt. Once the ignition switch is turned to "ON" or "START", the reminder light flashes and buzzer comes on if the driver's seat belt is not fastened. Unless the driver fastens the belt, the light stays flashing and the buzzer stops after about 4 to 8 seconds. (d) SRS Warning Light This indicator comes on when the ignition switch is turned to the "ON" position. It goes off after about 6 seconds. This means the SRS airbags and seat belt pretensioners are operating properly. The SRS warning light system monitors the airbag sensor assembly, front airbag sensors, side airbag sensors, occupant detection sensor, seat belt buckle switch, 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 parts monitored by the warning light system. Contact your Lexus dealer as soon as possible to service the vehicle. D When the ignition switch is turned to the "ON" position, the light does not come on, remains on or flashes. D The light comes on or starts flashing while driving. If the light stays on, it indicates that the SRS front airbags have a problem. If the light flashes, the SRS side airbags and/or seat belt pretensioners have a problem. (c) Front Passenger's Seat Belt Reminder Light This light reminds you to buckle up the front passenger's seat belt. Once the ignition switch 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 come on. 44
