D Brake system failure warning
The light may stay on for about 60 seconds after the engine
is started. It is normal if it goes out after a while.
If the brake system warning light stays on even with the
parking brake being released, the brake system may fail.
Contact your Lexus dealer.
If the hydraulic boost pressure is lowered, the warning light
comes on and buzzer sounds continuously. Immediately stop
your vehicle at a safe place and contact your Lexus dealer. If
this is a case the brakes may not work properly. If they do not
work well, depress the brake pedal firmly.
Depressing the brake pedal repeatedly may turn on the
warning light and buzzer. It is normal if the light goes out and
the buzzer stops sounding after a few seconds.

(b) Driver's Seat Belt Reminder Light and
Buzzer
Once the ignition key is turned to "ON" or "START", the
reminder light flashes and buzzer sounds 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) Front Passenger's Seat Belt Reminder
Light
Once the ignition key is turned to "ON" or "START", 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 stays flashing.
If luggage 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 come on.
