A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If either of the following conditions occurs, immediately
stop your
vehicle at a safe place and contact your Lexus
dealer.
The light does not turn off even after the parking
brake is released while the engine is running.
In this case, the brakes may not work properly and
your stopping distance will become longer. Depress
the brake pedal firmly and bring the vehicle to an
immediate stop.
The brake system warning light remains on together
with the “ABS” warning light.
In this case, not only the anti lock brake system will
fail but also the vehicle will become extremely
unstable during braking.
GS430 only—Any of the following conditions may occur,
but do not indicate the malfunction:
The light may stay on for about 60 seconds after the engine
is started. It is normal if it turns off after a while.
Depressing the brake pedal repeatedly may turn on the
warning light and buzzer. It is normal if the light turns off and
the buzzer stops sounding after a few seconds.
You may hear a small sound in the engine compartment
after the engine is started or the brake pedal is depressed
repeatedly. This is a pump pulsating sound of the brake
system, and it is not a malfunction.
(b) Brake System Warning Light (yellow)
The light comes on when the engine switch is selected in
“IG−ON” mode.
GS430—If the engine is started, and the traction control
system, vehicle stability control system and hill −start assist
control system work properly, the light turns off after a few
seconds. Thereafter, if any part of the system malfunctions,
the light comes on again.
GS300—If the engine switch is selected in “IG −ON” mode, and
the traction control system, vehicle stability control system and
hill −start assist control system work properly, the light turns off
after a few seconds. Thereafter, if any part of the system
malfunctions, the light comes on again.

checked by your Lexus dealer as soon as possible.
(c) Driver’s Seat Belt Reminder Light and Buzzer
The light and buzzer act as a reminder to have the driver buckle
up the seat belt.
GAUGES, METERS AND SERVICE REMINDER INDICATORS
78Once the engine switch is selected in “IG
−ON” mode, the
reminder light flashes and buzzer sounds if the driver’s seat
belt is not fastened. Unless the driver fastens the belt, the light
continues flashing and the buzzer stops after about 4 to 8
seconds.
If the vehicle speed exceeds about 15 km/h (10 mph) with the
driver’s seat belt reminder light flashing, beeps sound
intermittently for about 20 seconds.
(d) Front Passenger’s Seat Belt Reminder Light
The light acts as a reminder to have the front passenger buckle
up the seat belt.
Once the engine switch is selected in “IG −ON” mode, the
reminder light flashes if a passenger sits in the front passenger
seat and does not fasten the seat belt. Unless the front
passenger fastens the belt, the light continues flashing.
However, if a front passenger uses an additional seat cushion,
the indicator light may not flash even when the seat belt is not
buckled up.
If luggage or other 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 flash.
(e) SRS Warning Light
The indicator comes on when the engine switch is
selected in “IG ON” mode. 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 and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,
occupant detection sensor, front passenger’s seat belt buckle
switch, seat belt pretensioner assemblies, inflators, warning
light, interconnecting wiring and power sources.
If any of the following conditions occurs, this indicates a
malfunction of the airbags or seat belt pretensioners. Contact
your Lexus dealer as soon as possible to service the vehicle.
When the engine switch is selected in “IG−ON” mode, the
light does not come on or remains on for more than 6
seconds.
The light comes on while driving.
If the light stays on, it indicates that the SRS driver and front
passenger airba gs, SRS side and curtain shield airbags and/or
seat belt pretensioners have a problem.
