the light stays on and the buzzer stops after about 4 to
8 seconds.

This light comes on when the ignition key is turned
to the ªACCº or ªONº position. It goes off after

sensor assemblies, front airbag sensors, inflators, seat
belt pretensioners, warning light, interconnecting wiring

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

the battery properly.
 If the belt is O.K., there is a problem somewhere in the
charging system.

until the battery is discharged. Turn off the air
conditioning, blower, radio, etc., and drive directly to the
nearest Lexus dealer or repair shop.
