Active Traction Control System - Toyota 2001 Sequoia Owner's Manual

The brake actuator temperature increases
during continuous operation of the traction
control system or vehicle skid control sys-
tem such as on slippery roads. If the
brake actuator temperature becomes too
high while the traction control system or
vehicle skid control system is operating,
a buzzer will start to sound intermittently
to indicate that the traction control system
can no longer operate. In this case, imme-
diately 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 traction control system tempo-
rarily stops operating in order to protect
the brake actuator. (Although the 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.
When the "VSC/TRAC" warning light and
"TRAC OFF" indicator light come on the
traction control system does not operate,
but there is no problem to continue your
driving.

CAUTION
Under certain slippery road condi-
tions, full traction of the vehicles and
power to rear wheels cannot be main-
tained, even though the traction con-
trol system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which
cause the vehicle to lose traction. In
situations where the road surface is
covered with ice or snow, your ve-
hicle should be fitted with snow tires
or tire chains. Always drive at an ap-
propriate and cautious speed for the
road conditions present.

The active traction control system auto-
matically helps control the spinning of
4 wheels (4WD mode) or rear wheels
(2WD mode) which may occur when ac-
will
celerating on slippery road surfaces, by
controlling the output of the brake and
engine. Thus, the system assists driver
to control the driving power
wheels (4WD mode) or
(2WD mode).
When you turn the ignition switch on, the
active traction control system always turns
on automatically, and the slip indicator
light will come on. The indicator lights will
go off after about a few seconds.
