Use the “2WD/4HI” and “4LO” buttons
to select the following transfer modes.
1. “2WD” (high speed position, two wheel drive): “2WD/4HI” and “4LO”
buttons left out
Use this for normal driving on dry,
hard− surfaced roads. This position
gives greater economy, the quietest
ride and least wear.
2. “4HI” (high speed position, four wheel drive): “2WD/4HI” button pushed
in
The “4HI” (high speed four −wheel
drive) indicator light comes on when
the “4HI” mode is selected.
Use this for normal driving on wet, icy
or snow −covered roads. This position
provides greater traction than two −
wheel drive.
In this mode, the vehicle stability con-
trol system is off. (See “Vehicle stabil-
ity control system” in this Section.) 3. “4LO” (low speed position, four
wheel drive): With the “2WD/4HI”
button pressed in, push the “4LO”
button
The “4LO” (low speed four −wheel drive)
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 hills, 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 (button type)”
for further instructions.
Advice for driving on slippery roads in
“4LO” (low speed position, four wheel
drive) mode
If you push the “4LO” button with the
“2WD/4HI” button pressed in and shift the
automatic transmission lever to “2” when
you drive in steep off −road areas, the out-
put of the brake can be controlled effec-
tively by the traction control system,
which assists the driver to control the
driving power of 4 wheels.

Use the “L” position of the automatic
transmission lever for maximum power
and traction when your wheels get stuck
or when you drive down a steep incline.
In the following cases, the output of the
brake can be controlled by the traction
control system if the engine speed is un-
der 3000 rpm (normally engine speed is
under 3000 rpm when the wheels get un-
stuck).
The transfer mode in the “4LO” mode
and the automatic transmission lever in
the “L” position or the automatic trans-
mission lever in the “D” or “2” with the
transmission downshifting to the first
gear
The transfer mode in the “4LO” mode
and the automatic transmission lever in
the “R” position
(As for the automatic transmission lever
positions, see “Automatic transmission” in
this Section.) 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 “H2” AND “H4”
To shift from “H2” to “H4”,
reduce the
vehicle speed to less than 80 km/h (50
mph) and move the front drive control
lever. If the indicator light does not come
on when you shift the transfer into “H4”,
drive straight ahead while accelerating or
decelerating, or drive forward or backward
in a short distance. You need not depress
the clutch pedal.
If you have trouble shifting in cold weath-
er, reduce the vehicle speed or stop the
vehicle and reshift.
CAUTION
Never move the front drive control
lever if wheels are slipping. Stop the
slipping or spinning before shifting.
To shift from “H4” to “H2”, simply move
the front drive control lever.
This can be done at any speed. You need
not depress the clutch pedal.
If the indicator light does not go off when
you shift the transfer into “H2”, drive
straight ahead while accelerating or decel-
erating, or drive forward or backward in a
short distance.

Drive straight ahead while accelerating or
decelerating, or drive forward or backward
in a short distance. 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.

“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 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 “ON”.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
goes out after a few seconds.
The brake actuator temperature increases
during continuous operation of the above
mentioned systems such as on slippery
roads. If the brake actuator temperature
becomes too high while any of the sys-
tems is operating, a buzzer will start to
sound intermittently to indicate that the
traction control system can no longer op-
erate. 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 “VSC TRAC” warning light
will come on and the traction control sys-
tem 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 “VSC TRAC” warning
light goes off.
If the 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 on a slip-
pery 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.

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.CAUTION
Do not rely excessively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively to
avoid serious injury. Reckless driv-
ing will result in an unexpected ac-
cident. If the slip indicator light
blinks and an alarm sounds, special
care should be taken while driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” in
Section 72.)
