To shift from “L4” to “H4”, bring the
vehicle to a complete stop with the brake
pedal held down with your foot, shift the
automatic transmission selector lever into
“N” and turn the multi −mode control switch
knob counterclockwise. If the “4LO” (low speed four
−wheel drive)
indicator light continues to blink when you
operate the multi −mode control switch
knob to the “H4” or “L4” position, drive
forward or backward in a short distance,
then stop the vehicle completely, shift the
automatic transmission selector lever se-
curely into “N” and operate the switch
knob again.
If the indicator continues to blink even if
doing so, contact your Toyota dealer as
soon as possible. There may be a trouble
in the four −wheel drive system.
CAUTION
Never operate the multi mode control
switch knob if the wheels are slip-
ping. Stop the slipping or spinning
before operating.
The traction control system automatical-
ly helps prevent the spinning of rear
wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the ignition key is turned to “ON”,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power to the rear wheels cannot be
maintained, even though the traction
control system is in operation. Do not
drive the vehicle under any speed or
maneuvering conditions which may
cause the vehicle to lose traction
control. In situations where the road
surface is covered with ice or snow,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.

NORMAL DRIVING MODE
Leave the system on during ordinary
driving so that it can operate when
needed.
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 trac-
tion control system is in the self −check
mode, but does not indicate a malfunction.
When the traction control system is oper-
ating, the following conditions occur:
The system controls the spinning of the
rear wheels. At this time, the slip indi-
cator light blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
The slip indicator light comes on for a few
seconds when the ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.
The brake actuator temperature increases
during continuous operation of the traction
control system, the “AUTO LSD” system,
the vehicle stability control system and
the hill −start assist control system such
as on slippery roads. 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 traction control system can no
longer 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 buzzer
sounds for about 3 seconds.) At the time the slip indicator light will
come on and the traction control system
temporarily stops operating in order to
protect the brake actuator. (Although the
traction control system does not operate,
there is no problem to continue your driv-
ing.) The system will be automatically re-
stored after a short time and the slip indi-
cator light goes out.

Leave the system on during the ordi-
nary driving so that it can operate
when needed.
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 ac-
tive traction control system is in the self −
check mode, but does not indicate a mal-
function.
When the active traction control system is
operating, the following conditions occur:
The system controls the spinning of the
4 wheels. At this time, the slip indica-
tor light blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
The slip indicator light comes on for a few
seconds when the ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.
The brake actuator temperature increases
during continuous operation of the active
traction control system, the vehicle stabil-
ity control system, the downhill assist con-
trol system and the hill −start assist control
system such as on sli ppery roads. If the
brake actuator temperature becomes too
high while any of the systems is operat-
ing, a buzzer will start to sound intermit-
tently to indicate that the active traction
control system can no longer 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 buzzer
sounds for about 3 seconds.) At the time, the slip indicator light will
come on and the active traction control
system temporarily stops operating in or-
der to protect the brake actuator. (Al-
though the active 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 slip indicator light goes out.

NOTICE
Do not use the “AUTO LSD” system
in conditions other than the above. A
much greater steering effort and more
careful cornering control will be re-
quired.
To activate the system, push the “AUTO
LSD” switch with the vehicle stopped.
The “AUTO LSD” is activated when
driving at a speed under 100 km/h (62
mph). At this time, the “AUTO LSD”
indicator light will come on.
To cancel the system, push the “AUTO
LSD” switch once again.
If the engine is turned off while the
“AUTO LSD” indicator light is on and then
restarted, the indicator light will turn off
automatically.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 continuous operation of the “AUTO
LSD” system, the traction control system
and the vehicle stability control system
such as on slippery roads. 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 longer operate. In this case, immedi-
ately 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 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.
“VSC TRAC” warning light
This light warns that there is a problem
somewhere in the following.
“AUTO LSD” system
Traction control system
Vehicle stability control system
When the system is normal and the igni-
tion key is turned to “ON”, the light will
come on and will go off after a few sec-
onds.
It is not a malfunction that the warning
light may stay on for 60 seconds after the
ignition key is turned to “ON”. Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
goes out after a few seconds.
If the “VSC TRAC” warning light and slip
indicator light comes on while driving, the
“AUTO LSD” system does not work. How-
ever, as the brakes operate normally when
applied, it is no problem 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.
NOTICE
Do not drive with the “AUTO LSD”
switch continuously turned on.

The slip indicator light and downhill assist
control system indicator light come on for
a few seconds when the ignition key is
turned to “ON”. If any of the indicator
lights does not come on when the ignition
is turned on, contact your Toyota dealer.
The brake actuator temperature increases
during continuous operation of the hill −
start assist control system, the active
traction control system and the vehicle
stability control system. If the brake ac-
tuator temperature becomes too high while
any of the systems is operating, a buzzer
will start to sound intermittently to indicate
that the downhill assist 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 this time, the slip indicator light will
come on, the downhill assist control sys-
tem indicator light flash and the downhill
assist control system stops operating tem-
porarily in order to protect the brake ac-
tuator. (Although the downhill assist con-
trol system does not operate, it is no
problem to continue your driving.) The
system will be automatically restored after
a short time and the slip indicator light
and the downhill assist control system in-
dicator light go out.
If there is any abnormality in the sys-
tem, the “VSC TRAC” warning light will
come on. When the “DAC” switch is
pushed, the downhill assist control sys-
tem indicator light also flash.
If the “VSC TRAC” warning light comes
on, there may be an abnormality in any
of the following systems in addition to the
downhill assist control system.

“VSC TRAC” warning light
When the system is normal and the igni-
tion key is turned to “ON”, the warning
light will come on and will go off after a
few seconds.
It is not a malfunction that the warning
light may stay on for 60 seconds after the
ignition key is turned to the “ON” position.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
goes out after a few seconds.
If the warning light comes on while driv-
ing, the system does not work. However,
as normal braking operates when being
applied, it is no problem 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 hill start assist control system as-
sists you in starting to move up a
steep or slippery hill. When you start
to move up the hill slope, the system
helps to prevent the vehicle from roll-
ing backward in the interval while you
move your foot from the brake pedal to
the accelerator pedal.
CAUTION
Do not rely excessively on the h
ill
start assist control system. The ve-
hicle may not be able to start
smoothly on road surfaces or off
road surfaces such as extremely
steep slopes or icy roads, on which
sliding can occur very easily.
Do not use the hill start assist con-
trol system to stop the vehicle. This
system is not designed as a func-
tion for stopping the vehicle on a
uphill slope.
The hill start assist control system will
operate for 5 seconds maximally when
all of the following conditions apply.
When the transmission is in any of
positions “D”, “4”, “3”, “2” or “L”
When the brake pedal is not de-
pressed
The system is designed to operate when
the vehicle is starting on an uphill slope;
therefore, if the transmission is in “P” or
“N” it will not operate. It will not operate
either if the vehicle starts to move in
reverse on a slope with the transmission
in the “R”.

When the hill−start assist control system
is operating, the slip indicator light flashes
and an alarm sounds intermittently. At the
same time, the stop lamps and high
mounted stoplight are lit.
The slip indicator light comes on for a few
seconds when the ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer. Keep in mind the following when driv-
ing.
The hill−
start assist control system op-
erates for 5 seconds maximally. If both
the brake and accelerator pedals re-
main undepressed for longer than 5
seconds, the buzzer will sound at more
frequent intervals and the system will
gradually stop operating.
The hill −start assist control system is
not designed as a function for stopping
the vehicle on a uphill slope. When
stopping the vehicle, be sure to de-
press the brake pedal.
The brake actuator temperature increases
during continuous operation of the downhill
assist control system (four −wheel drive
models), the traction control system (two−
wheel drive models), the active traction
control system (four −wheel drive models),
the vehicle stability control system and
the “AUTO LSD” system (two −wheel drive
models) on such as slippery roads. If the
brake actuator temperature becomes too
high while any of the systems is operat-
ing, a buzzer will start to sound intermit-
tently to indicate that the hill −start assist
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 this time, the slip indicator light will
come on and the hill
−start assist control
system stops operating temporarily in or-
der to protect the brake actuator. (Al-
though the hill −start assist control system
does not operate, it is no problem to con-
tinue your driving.) The system will be
automatically restored after a short time
and the slip indicator light goes out.
