If the slip indicator light does not come on
when the ignition is turned on, contact
your Toyota dealer.
When the active traction control is ap-
plied, the slip indicator light blinks.
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
is started. This means that the active
traction control system is in the self−
check mode, and does not indicate mal-
function. When the traction control system
is operating, you may feel vibration or
noise of your vehicle, caused by operation
of the brakes. This indicates the system
is functioning properly.
When getting the vehicle out of mud or
new snow, etc. the active traction control
system will help operate to prevent the
wheels from spinning.

Active traction control system failure
warning
These lights warn that when there is a
problem somewhere in the active traction
control system.
If the "VSC/TRAC" warning light and "VSC
OFF" indicator light come on, have your
vehicle checked by Toyota dealer as soon
as possible.
The lights will come on when the ignition
key is turned on, and will go off after a
few seconds.
2001 SEQUOIA (OM34414U)
The brake actuator temperature increases
during continuous operation of the active
traction control system or vehicle skid
control system such as on slippery roads.
If the brake actuator temperature becomes
too high while the active traction control
system or vehicle skid control system is
operating, a buzzer will start to sound
intermittently to indicate that the active
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 buzzer sounds for about
3 seconds.) At the time, the "VSC/TRAC"
warning light will come on and the active
traction control system temporarily stops
operating in order to protect the brake
actuator. (Although the active traction con-
trol 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.
When the "VSC/TRAC" warning light and
"VSC OFF" indicator light come on the
active traction control system does not
operate, but there is no problem to contin-
ue your driving.
