Finish GAUGES, METERS AND SERVICE REMINDER INDICATORS (c) Front Passenger's Seat Belt Reminder Light This light reminds you to buckle up the front passenger's seat belt. Once the ignition key is turned to the "ON" position, the reminder light flashes if a front passenger sits in the front passenger seat and does not fasten the seat belt. Unless the front passenger fastens the belt, the light keeps flashing. If luggage 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. If any 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 driver and front passenger airbags fail. If the light flashes, the side and curtain shield airbags and/or seat belt pretensioners fail. (e) Discharge Warning Light This light warns that the battery is being discharged. If it comes on while you are driving, stop the vehicle, turn off the engine, and check for the cause. Look first at the engine drive belt. D If it is loose or broken, the generator will not charge the battery properly. D If the belt is O.K., there is a problem somewhere in the charging system. The engine ignition will continue to operate, however, until the battery is discharged. Turn off the air conditioning, blower, radio, etc., and drive directly to the nearest Lexus dealer or repair shop. (d) SRS Warning Light This light comes on when the ignition key is turned to the "ON" position. It goes off after about 6 seconds.
