The brake pad or actuator temperature
increases during continuous operation of
the active traction control system or ve-
hicle stability control system such as on
slippery roads. If the brake pad or actua-
tor temperature becomes too high while
the active traction control system or ve-
hicle stability control system is operating,
a buzzer will start to sound intermittently
to indicate that the active traction control
system can no longer operate. In this
case, stop your vehicle immediately at a
safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
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 pad. (Although
the active traction control system does not
operate, there is no problem to continue
your driving.) The system will be automati-
cally restored after a short time and the
warning light goes out.
If the light comes on while driving, the
active traction control system does not
work. However, as conventional braking
operates when applied, there is no prob-
lem to continue your driving.
In the following cases, contact your Toyota
dealer:
! The warning light does not come on
after the ignition key is turned to “ON”.
! The warning light remains on after the
ignition key is turned to “ON”.
! The warning light comes on while driv-
ing.
The “VSC OFF” indicator light will come
on when the “VSC TRAC” warning light
comes on even if the center differential
lock switch is not pushed.
The vehicle stability control system
helps provide integrated control of the
systems such as anti−lock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the brakes and engine to help prevent
the vehicle from skidding when corner-
ing on a slippery road surface or oper-
ating steering wheel abruptly.
This vehicle stability control activates
when the vehicle speed is more than the
following speed.
Two−wheel drive models:
15 km/h (9 mph)
Four−wheel drive models:
“2WD” or “4HI” mode
15 km/h (9 mph)
“4LO” mode 30 km/h (18 mph)
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the sys-
tem is in the self−check mode but does
not indicate a malfunction.
