GAUGES, METERS AND SERVICE REMINDER INDICATORS
56If the brake fluid level is correct ...
Have the warning system checked by your Lexus dealer.
(b) Seat Belt Reminder Light and Buzzer
Once the ignition key is turned to ºONº or ºSTARTº, the
reminder
light flashes and buzzer comes on if the driver's seat
belt is not fastened. Unless the driver fastens the belt, the light
stays flashing and the buzzer stops after about 4 to 8 seconds.
(c) SRS Airbag Warning Light
This indicator comes on when the ignition key is turned to
the ºACCº or ºONº position. It goes off after about 6
seconds. This means the SRS airbag system is operating
properly.
The SRS airbag warning light system monitors the airbag
sensor assembly, 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.

The light does not come on as described above or remains
on.

The light comes on while driving.
(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.

If it is loose or broken, the generator will not charge the
battery properly.

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.
(e) Low Oil Pressure Warning Light
This light warns that the engine oil pressure is too low.
If it flickers or stays on while you are driving, pull off the road
to a safe place and stop the engine immediately. Call a Lexus
dealer or qualified repair shop for assistance.

Do no put anything other than a cassette tape or CD
magazine into the cassette tape slot or CD changer.

The use of cellular phone inside or near the vehicle
may cause a noise from the speakers of the audio
system which you are listening to. However, this does
