GAUGES, METERS AND SERVICE REMINDER INDICATORS Once the engine switch is selected in "IG−ON" mode, 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. If the vehicle speed exceeds about 15 km/h (10 mph) with the driver's seat belt reminder light flashing, beeps sound intermittently for about 20 seconds. (e) SRS Warning Light The indicator comes on when the engine switch is selected in "IG−ON" mode. It goes off after about 6 seconds. This means the SRS airbags and 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, occupant detection sensor, front passenger's seat belt buckle switch, 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 engine switch is selected in "IG−ON" mode, the light does not come on or remains on for more than 6 seconds. D The light comes on while driving. If the light stays on, it indicates that the SRS driver and front passenger airbags, SRS side and curtain shield airbags and/or seat belt pretensioners have a problem. (d) 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 engine switch is selected in "IG−ON" mode, 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. However, if a front passenger uses an additional seat cushion, the indicator 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. 76
