"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 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 (two–
wheel drive vehicles), the active traction
control system (four–wheel drive vehicles)
and the vehicle skid control system do not
operate, but the brake system still oper-
ates 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 TRAC" 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).
'02 4Runner_U (L/O 0108)
If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the parts monitored by the
warning light system. Contact your To-
yota dealer as soon as possible to ser-
vice the vehicle.
D
The light does not come on when the
ignition key is turned to the "ON" posi-
tion, or remains on.
D
The light comes on while you are dri-
ving.
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.
2002 MY 4RUNNER_U (OM35787U)
Either of the following conditions do
not indicate the malfunction.
D
The light may stay on for about 60
seconds after the ignition key is turned
to the "ON" position. It is normal if it
turns off after a while.
D
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
turns off after a few seconds.
BRAKE ASSIST SYSTEM
When you slam the brakes on, the
brake assist system judges as an emer-
gency stop and provides more powerful
braking for a driver who cannot hold
down the brake pedal firmly.
When you slam the brakes on, more pow-
erful braking will be applied. At this time,
you may hear a sound in the engine
compartment and feel the vibrations of the
brake pedal. This does not indicate a mal-
function.
The brake assist system becomes opera-
tive after the vehicle has accelerated to
a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
