"VSC TRAC" warning light
This light warns that there is a problem
somewhere in the following.
"AUTO LSD" system
D
Traction control system
D
Vehicle stability control system
D
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".
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
"AUTO LSD" system can no longer oper-
ate. 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 "AUTO LSD" system
temporarily stops operating in order to
protect the brake actuator. (Although the
"AUTO LSD" system does not operate, it
is no problem to continue driving.) The
system will be automatically restored after
a short time and the "VSC TRAC" warning
light goes off.
If the light comes on while driving, the
"AUTO LSD" system does not work. How-
ever, as the brakes operate normally when
applied, it is no problem to continue your
driving.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
D
after the ignition key is turned to "ON".
The warning light remains on after the
D
ignition key is turned to "ON".
The warning light comes on while driv-
