"VSC TRAC" warning light
This light warns that there is a problem
somewhere in the following.
D
Traction control system
D
Vehicle skid control system
D
Hill–start assist control system
When the system is normal and the igni-
tion key is turned to "ON", the warning
light will come on and will go off after a
few seconds.
It is not a malfunction that the warning
light may stay on for 60 seconds after the
ignition key is turned to "ON".
'03 4Runner_U (L/O 0211)
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
goes out after a few seconds.
The brake actuator temperature increases
during continuous operation of the above
mentioned systems such as on slippery
roads. If the brake actuator temperature
becomes too high while any of the sys-
tems is operating, a buzzer will start to
sound intermittently to indicate that the
traction control system can no longer op-
erate. In this case, immediately stop your
vehicle at a safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous
sounds for about 3 seconds.)
At the time the "VSC TRAC" warning light
will come on and the traction control sys-
tem temporarily stops operating in order to
protect the brake actuator. (Although the
traction control system does not operate,
there is no problem to continue your driv-
ing.) The system will be automatically re-
stored after a short time and the "VSC
TRAC" warning light goes out.
If the light comes on while driving, the
traction control system does not work.
However, as normal
when being applied, there is no problem
to continue your driving.
In the following cases, contact your Toyota
dealer:
D
The warning light does not come on
after the ignition key is turned to "ON".
D
The warning light remains on after the
ignition key is turned to "ON".
D
The warning light comes on while driv-
ing.
