Use the front drive control switches
and center differential lock switch to
select the transfer and center differen-
tial modes.
In the ª4HIº and ª4LOº mode, you can
choose to lock or unlock the center differ-
ential.
Use the center differential lock system if
your wheels get stuck in a ditch, or when
you are driving on a slippery or bumpy
surface. When the center differential is
locked, the vehicle stability control system
is automatically turned off and the center
differential lock and ªVSC OFFº indicator
lights come on because the function that
controls engine performance interferes
with the process of freeing your wheels.
NOTICE
As soon as the center differential lock
switch is turned on, the ªVSC OFFº
indicator light comes on. After the
wheels are out of the ditch or off the
slippery or bumpy surface, turn the
center differential lock switch off.
Make sure that the center differential
lock indicator light and ªVSC OFFº
indicator light turn off.
ª2WDº mode (high speed, two±wheel
drive)
This mode is the normal driving mode. In
this mode, the ª4HIº and ª4LOº indicator
lights are turned off.
Use this for normal driving on dry hard±
surfaced roads. This position gives greater
economy, quietest ride, least wear and
better vehicle control.
ª4HIº mode (high speed, four±wheel
drive, center differential unlocked)
To select this mode, press the ª2WD/4HIº
switch only. The ª4HIº indicator light
comes on.
Use this for normal driving on all types of
roads, from dry hard±surfaced roads to
wet, icy or snow±covered roads. This
position provides greater traction than
two±wheel drive.ª4HIº mode (high speed, four±wheel
drive, center differential locked)
To select this mode, press the ª2DW/4HIº
switch, and then the center differential
lock switch. The ª4HIº and the center dif-
ferential lock indicator lights come on.
Use this for greater traction when you
experience a loss of power, such as
wheel slipping, in the center differential
unlock mode.
ª4LOº mode (low speed, four±wheel
drive, center differential unlocked)
To select this mode, press the ª4LOº
switch only. The ª4LOº indicator light
comes on.
Use this for maximum power and traction.
Use this for climbing steep hills, off±road
driving, and hard pulling in sand or mud.
In this mode, the braking feeling that oc-
curs when the wheels are negotiating a
sharp corner is further reduced than in the
ª4LOº (low speed, four±wheel drive, center
differential locked) mode.

once again.
The ªTRAC OFFº indicator light will go off.The traction control system will automati-
cally go on, and the ªTRAC OFFº indicator
light will go off when you drive over 30
km/h (19 mph) even if the ªTRAC OFFº
switch is pushed to cancel the traction
control system.
ªTRAC OFFº indicator light comes on for
a few seconds when the ignition key is
turned to ªONº. It will come on again
when you push the ªTRAC OFFº switch to
turn off the system.
In the following cases, contact your Toyota
dealer:
The indicator light does not come on
when the ignition key is turned ªONº.

The brake pad or actuator temperature
increases during continuous operation of
the traction control system or vehicle sta-
bility control system such as on slippery
roads. If the brake pad or actuator tem-
perature becomes too high while the trac-
tion control system or vehicle stability
control system is operating, a buzzer will
start to sound intermittently to indicate
that the traction 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 the time the ªVSC TRACº warning light
will come on and the traction control sys-
tem temporarily stops operating in order to
protect the brake pad. (Although the trac-
tion 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 warning
light goes out.
If the light comes on while driving, the
traction control system does not work.
However, as conventional braking operates
when applied, there is no problem to con-
tinue your driving.In the following cases, contact your Toyota
dealer:

The warning light does not come on
after the ignition key is turned to ªONº.

The warning light remains on after the
ignition key is turned to ªONº.

The warning light comes on while driv-
ing.
The ªTRAC OFFº indicator light will come
on when the ªVSC TRACº warning light
comes on even if the ªTRAC OFFº switch
is not pushed.The active traction control system auto-
matically helps prevent the spinning of
4 wheels (4WD mode) or rear wheels
(2WD mode) when the vehicle is started
or accelerated on slippery road sur-
faces.
When the ignition key is turned to ªONº,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against 4 wheels (4WD mode)
or rear wheels (2WD mode) cannot be
maintained, even though the active
traction control system is in opera-
tion. 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.

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 (4WD mode) or rear wheels
(2WD mode). 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 ªONº. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.
ªVSC TRACº warning light

The brake pad or actuator temperature
increases during continuous operation of
the active traction control system or ve-
hicle stability control system such as on
slippery roads. If the brake pad or actua-
tor temperature becomes too high while
the active traction control system or ve-
hicle stability control system is operating,
a buzzer will start to sound intermittently
to indicate that the active traction 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 the time, the ªVSC TRACº warning light
will come on and the active traction con-
trol system temporarily stops operating in
order to protect the brake pad. (Although
the active traction control system does not
operate, there is no problem to continue
your driving.) The system will be automati-
cally restored after a short time and the
warning light goes out.
If the light comes on while driving, the
active traction control system does not
work. However, as conventional braking
operates when applied, there is no prob-
lem 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 ªONº.

The warning light remains on after the
ignition key is turned to ªONº.

The warning light comes on while driv-
ing.
The ªVSC OFFº indicator light will come
on when the ªVSC TRACº warning light
comes on even if the center differential
lock switch is not pushed.The vehicle stability control system
helps provide integrated control of the
systems such as anti±lock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the brakes and engine to help prevent
the vehicle from skidding when corner-
ing on a slippery road surface or oper-
ating steering wheel abruptly.
This vehicle stability control activates
when the vehicle speed is more than the
following speed.
Two±wheel drive models:
15 km/h (9 mph)
Four±wheel drive models:
ª2WDº or ª4HIº mode
15 km/h (9 mph)
ª4LOº mode 30 km/h (18 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.
