"VSC TRAC" warning light
This light warns that there is a problem
somewhere in the following.
D
Active traction control system
D
Vehicle skid control system
D
Downhill assist 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
active traction control system can no lon-
ger operate. 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 active traction con-
trol system temporarily stops operating in
order to protect the brake actuator. (Al-
though the active traction control system
does not operate, there is no problem to
continue your driving.) The system will be
automatically restored after a short time
and the "VSC TRAC" warning light goes
out.
If the light comes on while driving, the
active traction control system does not
work. However, as normal braking oper-
ates when being applied, there is no prob-
lem 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.
