Srs Warning Light; Discharge Warning Light - Lexus RX300 2003 Owner's Manual

(d) SRS Warning Light
The indicator comes on when the ignition key is turned to
the "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 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 parts monitored by the warning
light system. Contact your Lexus dealer as soon as possible
to service the vehicle.
D When the ignition key is turned to the "ON" position, the light
does not come on, remains 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 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.
NOTICE
Do not continue driving if the engine drive belt is broken
or loose.
