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 ABSº warning light.
In this case, not only the anti-lock brake system will
fail but also the vehicle will become extremely
unstable during braking.

fastened. Unless the driver fastens the belt, the light stays on
and the buzzer stops after about 4 to 8 seconds.
(c) Front Passenger's Seat Belt Reminder Light

belt.
Once the ignition key is turned to the ONº position, the
reminder light flashes if a front passenger sits in the front
passenger seat and does not fasten the seat belt.
If luggage or other load is placed on the front passenger seat,
depending on its weight, the reminder light may come on.
(d) SRS Warning Light
This light comes on when the ignition key is turned to the
ONº position. It goes off after about 6 seconds. This
means the SRS airbags and front seat belt pretensioners

STARTING AND DRIVING
289 You may hear a click or motor sound in the engine
compartment for a few seconds when the engine is started or
just after the vehicle begins to move. This means that the
anti-lock brake system is in the self-check mode, and does not
indicate a malfunction.
When the anti-lock brake system is activated, the
following conditions may occur. They do not indicate a
malfunction of the system:
You may hear the anti-lock brake system operating and feel
the brake pedal pulsating and the vibrations of the vehicle
body and steering wheel. You may also hear the motor
sound in the engine compartment even after the vehicle is
stopped.
At the end of the anti-lock brake system activation, the
brake pedal may move a little forward.
CAUTION
Do not overestimate the anti-lock brake system:
Although the anti-lock brake system assists in
providing vehicle control, it is still important to drive
with all due care and maintain a moderate speed and
safe distance from the vehicle in front of you, because
there are limits to the vehicle stability and effectiveness
of steering wheel operation even with the anti-lock
brake system on.
If tire grip performance exceeds its capability, or if
hydroplaning occurs during high speed driving in the
rain, the anti-lock brake system does not provide
vehicle control.
Anti-lock brake system is not designed to shorten the
stopping distance: Always drive at a moderate speed
and maintain a safe distance from the vehicle in front of
you. Compared with vehicles without an anti-lock
brake system, your vehicle may require a longer
stopping distance in the following cases:
Driving on rough, gravel or snow-covered roads.
Driving with tire chains installed.
Driving over the steps such as the joints on the road.
Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at appropriate inflation
pressure: The anti-lock brake system detects vehicle
speeds using the speed sensors for respective wheels'
turning speeds. The use of tires other than specified
may fail to detect the accurate turning speed resulting
in a longer stopping distance.
