"ABS" warning light
The light comes on when the ignition key
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 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
"AUTO LSD" system, the vehicle stability
control system do 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.
"VSC TRC" warning light may come on
with the "ABS" warning light (brake assist
system warning light) when there is a mal-
function somewhere in the anti−lock brake
system (brake assist system).
If either of the following conditions
occurs, this indicates
somewhere in the components moni-
tored by the warning light system. Con-
tact your Toyota dealer as soon as
possible to service the vehicle.
The light does not come on when the

ignition key is turned to the "ON" posi-
tion, or remains on.

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 warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the anti−lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
