“4LO” mode (low speed, fourwheel
drive, center differential locked)
To select this mode, press the “4LO”
switch, and then press the center differen-
tial lock switch. The “4LO” and the center
differential lock indicator lights come on.
Use this for maximum power and traction.
Use this for hard pulling in situations the
vehicle cannot negotiate even in “4LO”
(low speed, four−wheel drive, center differ-
ential unlocked) mode. Also, using this
mode when driving down steep off −road
inclines will help contribute to increased
vehicle stability.
The indicator light tells when the differen-
tial lock is engaged. Note that the differ-
ential is not still locked as long as the
indicator light remains off.
When the operation is not completed, the
indicator blinks. If the indicator light does
not go off when you push out the center
differential lock switch, drive straight
ahead while accelerating or decelerating,
or drive in reverse.
If the center differential lock system op-
eration is not completed within 5 seconds
while the cruise control system is set,
cancel the cruise control system. To can-
cel the cruise control system, see “Cruise
control” on page 208 in Section 1 −7. If the indicator blinks even if doing so,
contact your Toyota dealer as soon as
possible. There may be a trouble in the
center differential lock system.
See “(c) Shifting procedure” for further in-
structions.
Advice for driving on slippery roads in
“4LO” (low speed, fourwheel drive)
mode
If you press the “4LO” switch and shift
the automatic transmission lever to “2”
when you drive in steep off
−road areas,
the output of the brake can be controlled
effectively by the active traction control
system, which assists the driver to control
the driving power of 4 wheels.
Use the “L” position of the automatic
transmission for maximum power and trac-
tion when your wheels get stuck or when
you drive down a steep incline. The output
of the brake can be controlled by the
active traction control system if the engine
speed is under 3000 rpm (normally engine
speed is under 3000 rpm when the wheels
get unstuck), in the following cases:
The front drive control in “4LO” mode
and the automatic transmission in “L”
or the automatic transmission in “D”,
“3” or “2” with the transmission down-
shifting to the first gear
The front drive control in “4LO” mode
and the automatic transmission in “R”
(As for the automatic transmission shift
positions, see “Automatic transmission” on
page 175 in this Section.)

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 against 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 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. 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 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 “VSC TRAC” 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 “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.
The “TRAC OFF” indicator light will come
on when the “VSC TRAC” warning light
comes on even if the “TRAC OFF” 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 “ON”,
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.

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,

ing.
The “VSC OFF” indicator light will come
on when the “VSC TRAC” 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 antilock 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.
The vehicle stability control system is acti-
vated when the vehicle speed is more
than the following speed.
Tw o
−wheel drive models:
15 km/h (9 mph)

1: Height control mode select switch
2: Height control switch
This rear height control air suspension
controls the vehicle height depending
on vehicle driving conditions.
You can choose automatic control mode
or manual control mode. In automatic
control mode, you can select the ve-
hicle height between “HI” (high), “N”
(normal) and “LO” (low) modes with the
height control switch. In manual control
mode, you can adjust the vehicle height
seamlessly with the height control
switch.
To change the mode between automatic
control mode and manual control mode,
use the height control mode select switch.The vehicle height is automatically ad-
justed to a selected height mode. Howev-
er, when the front drive control is in “4LO”
mode, the vehicle height cannot be ad-
justed automatically even if the vehicle
condition changes, but height mode can
be changed manually with the height con-
trol switch.
(a) Vehicle height modes
“N” (normal) mode—
The vehicle height in this mode is stan-
dard. Regardless of the number of occu-
pants or the luggage loading condition, the
vehicle height is always automatically ad-
justed to a fixed height in this mode while
the engine is running.
This mode is suitable for ordinary driving.
“HI” (high) mode—
The vehicle height is about 40 mm (1.6
in.) higher at rear than “N” mode height.
This mode is suitable when driving on
bumpy roads and through water.
However, when the vehicle speed exceeds
30 km/h (18 mph) in “HI” mode, “N” mode
is automatically selected.
CAUTION
“HI” mode should be only used for
severe offroad driving conditions.
Because the vehicle’s center of gravi-
ty is higher in this setting, the ve-
hicle may become unstable when
turning abruptly, resulting in an acci-
dent.

tion continues for up to 35 seconds. If,
within this 35 seconds, any of the side
doors or the back door is opened, opera-
tion will continue for a further 15 seconds.
When adjusting the vehicle height with
one or more doors open, make sure that
there is nothing that might come into con-
tact with the vehicle body or around the
doors.
