wheel drive): With the “2WD/4HI”
switch pressed in, push the “4LO”
switch
The “4LO” indicator light comes on
when the “4LO” mode is selected.
Use this for maximum power and trac-
tion. Use “4LO” mode for climbing or
descending steep h ills, off−road driving,
and hard pulling in s and, mud or deep
snow.
In this mode, the vehicle stability con-
trol system is off. (See “Vehicle stabil-
ity control system” in this Section.)
See “(c) Shifting procedure” for further
instructions. The A.D.D. can be engaged or disen-
gaged by the shifting operations de-
scribed in “(c) Shifting procedure”.
You should drive in four
−wheel drive for
at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated. SHIFTING BETWEEN “2WD” AND “4HI”
To shift from “2WD” to “4HI”,
reduce
the vehicle speed to less than 100 km/h
(62 mph) and push in the “2WD/4HI”
switch.
If the “4HI” indicator light flashes when
you push in the “2WD/4HI” switch, this
reminds you that the transfer mode is not
securely in “4HI” mode. Drive straight
ahead while accelerating or decelerating.
If the “4HI” indicator light flashes and the
buzzer sounds when you push in the
“2WD/4HI” switch, this reminds you that
the transfer mode is not in “4HI” mode.
Reduce the vehicle speed to less than
100 km/h (62 mph). Push the switch to

The traction control system automatical-
ly helps prevent the spinning of rear
wheels (twowheel drive models) or 4
wheels (fourwheel drive models) 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 (twowheel
drive models) or 4 wheels (fourwheel
drive models) cannot be maintained,
even though the traction control sys-
tem is in operation. Do not drive the
vehicle under any speed or maneuver-
ing conditions which may cause the
vehicle to lose traction control. In si-
tuations 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
present road conditions.

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 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 (two −wheel drive models)
or 4 wheels (four −wheel drive models).
At this time, the slip indicator 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 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 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,
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.
Traction control system
Vehicle stability control system
“AUTO LSD” 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
traction control system does not work.
However, 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.
The “AUTO LSD” system aids traction
by using the traction control system to
control engine performance and braking
when one of the rear wheels begins to
spin.
This system is used only when wheel
spinning occurs in a ditch or rough
surface.
This system is effective in case one of
the rear wheels is spinning.
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.

The driving mode is set in the two −
wheel drive mode (in the four −wheel
drive mode, the system does not
work.)
Driving at a speed under 100 km/h (62
mph)
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 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 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.

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 vehicle stability control system
helps provide integrated control of the
systems such as antilock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the output of the brakes or engine to
help prevent the vehicle from skidding
when cornering on a slippery road sur-
face or operating steering wheel abrupt-
ly.
The vehicle stability control activates
when the vehicle speed is more than 15
km/h (9 mph).
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 sys-
tem is in the self
−check mode, but does
not indicate a malfunction.
