Type A
Type B
"ABS" warning light
Vehicles without the vehicle stability
control system—
The light comes on when the ignition key
is turned to the "ON" position. If the anti−
lock brake system works properly, the
light turns off after a few seconds. There-
after, if either of the systems malfunc-
tions, 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 does not operate,
but the brake system still operates con-
ventionally.
When the "ABS" warning light is on (and
the brake system warning light is off), the
anti−lock brake system does not operate
but the brake assist system still operates.
In this case the wheels could lock up
during a sudden braking or braking on
slippery road surfaces.
