Drum-In-Disc Type Parking Brake System - Lexus 2004 LS430 Owner's Manual

STARTING AND DRIVING
"ABS" warning light
31L350
" 1 U.S.A. 2 Canada
The light comes on when the ignition switch is turned to the
"ON" position. If the anti-lock brake system and the brake
assist system work properly, the light turns off after a few
seconds. Thereafter, if either of the systems malfunctions, the
light comes on again.
When the "ABS" warning light is on (and the brake system
warning light is off), the anti-lock brake system, the brake
assist system, the traction control system and/or the vehicle
stability control system do/does not operate, but the brake
system still operates conventionally.
When the "ABS" warning light is on (and the brake system
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.
366
If any of the following conditions occurs, this indicates a
malfunction somewhere in the components monitored by
the warning light system. Contact your Lexus dealer as
soon as possible to service the vehicle.
D The light does not come on when the ignition switch is
turned to the "ON" position, or remains on.
D The light comes on while you are driving.
A warning light turning on briefly during operation does not
indicate a problem.
CAUTION
If the "ABS" warning light remains on together with the
brake system warning light, immediately stop your
vehicle at a safe place and contact your Lexus dealer.
In this case, not only the anti-lock brake system will fail
but also the vehicle will become extremely unstable
during braking.
