2003 SC430 from May ’03 Prod. (OM24449U)
Have your vehicle checked at your Lexus dealer in the
following cases:
The light does not come on even if the parking brake is
applied when the ignition switch is turned to the “ON”
position.
The light does not come on even if the ignition switch is
turned on with the parking brake released.
A warning light turned 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.
The warning buzzer comes on together with the
warning light.
In either case, this can indicate that 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.
Any of the following conditions may occur, but do not
indicate the malfunction:
The light may stay on for about 60 seconds after the ignition
switch is turned to the “ON” position. 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.
