(b) Seat Belt Reminder Light and Buzzer
This light and buzzer remind you to buckle up the driver's
seat belt.
Once the ignition key is turned to "ON" or "START", the
reminder light and buzzer come on if the driver's seat
belt is not fastened. Unless the driver fastens the belt,
the light stays on and the buzzer stops after about 4 to
8 seconds.
(c) SRS Warning Light
This light comes on when the ignition key is turned
to the "ACC" or "ON" position. 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 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 The light does not come on as described above.
D The light stays 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
GAUGES, METERS AND SERVICE REMINDER INDICATORS
passenger airbags fail. If the light flashes, the side
airbags and/or seat belt pretensioners fail.
(d) 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.
