Make sure the "AUTO LSD" indicator light
comes on under the above condition when
you use the "AUTO LSD" system.
The slip indicator light blinks when the
system is controlling the spinning of the
rear wheels.
The "AUTO LSD" and slip indicator lights
come on for a few seconds when the
ignition key is turned to "ON". If the indi-
cator lights does not come on when the
ignition key is turned to "ON", contact
your Toyota dealer.

The brake actuator temperature increases
during the traction control system, vehicle
stability control system or "AUTO LSD"
system operating. If the brake actuator
temperature becomes too high while any
of the systems is operating, a buzzer will
start to sound intermittently to indicate
that the "AUTO LSD" system can no lon-
ger operate. 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 slip indicator 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 slip indicator light
goes off.
