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.
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
key is turned to the ªONº 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.
(b) Driver's 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 ºONº or ºSTARTº, 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
This light reminds you to buckle up the front passenger's seat
belt.
Once the ignition key is turned to ºONº or ºSTARTº, 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. However,
if a front passenger uses an additional seat cushion, the 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 come on.

warning light is off), the anti±lock brake system does not
operate so that the wheels could lock up during a sudden
braking or braking on slippery road surfaces.
