Toyota 2001 HIGHLANDER Owner's Manual page 116

While the "VSC" warning light and "TRAC
OFF" indicator/warning light come on, the
traction control system cannot be oper-
ated.
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 traction
control system is in the self–check mode,
and does not indicate malfunction.
When the traction control system is oper-
ating, you may feel vibration or noise of
your vehicle, caused by operation of the
brakes. This indicates the system is func-
tioning properly.
When getting the vehicle out of mud or
new snow, etc. the traction control system
will help operate to prevent the wheels
from spinning.

You can turn off the traction control
system by pushing the "TRAC OFF"
switch. The "TRAC OFF" indicator/warn-
ing light will come on. Pushing the
"TRAC OFF" switch a second
turns on the traction control system
again and the "TRAC OFF" indicator/
warning light will go off. At this time,
the vehicle skid control also turns off
and on simultaneously.

TRACTION CONTROL SYSTEM FAILURE
WARNING
These lights warn that there is a problem
somewhere in the vehicle skid control sys-
time
tem or traction control system.
The lights will come on when the ignition
key is turned to "ON", and will go off after
about a few seconds.
If the "VSC" warning light and "TRAC
OFF" indicator/warning light come on, the
vehicle skid control system and traction
control system do not work. However, as
conventional braking operates when ap-
plied, there is no problem to continue your
driving.
