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.

TRACTION CONTROL OFF MODE
If your wheels get stuck in a ditch
when you are driving on a severe off
road and sand, turn off the traction
control system. This system that con-
trols engine performance interferes with
the process of freeing your wheels.
To turn off: Push “TRAC OFF” switch.
The “TRAC OFF” indicator light will come
on.
The vehicle stability control system is al-
ways activated, even if the traction control
system is turned off.
To turn on: Push “TRAC OFF” switch
once again.
The “TRAC OFF” indicator light will go off.The traction control system will automati-
cally go on, and the “TRAC OFF” indicator
light will go off when you drive over 30
km/h (19 mph) even if the “TRAC OFF”
switch is pushed to cancel the traction
control system.
“TRAC OFF” indicator light comes on for
a few seconds when the ignition key is
turned to “ON”. It will come on again
when you push the “TRAC OFF” 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 “ON”.
The indicator light remains on after the
ignition is turned on.
The indicator light comes on with the
normal driving mode while driving.
“VSC TRAC” warning light

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,
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 “VSC TRAC” 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 “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
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.
This vehicle stability control activates
when the vehicle speed is more than the
following speed.
Tw o
−wheel drive models:
15 km/h (9 mph)
Four −wheel drive models:
“2WD” or “4HI” mode 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.

“LO” (low) mode—
Tw o−wheel drive models—The vehicle
height is about 15 mm (0.6 in.) lower at
rear than “N” mode height.
Four −wheel drive models—The vehicle
height is about 30 mm (1.2 in.) lower at
rear than “N” mode height.
This mode allows for easy access to the
vehicle (getting in and out) and easy load-
ing and unloading.
This mode is available when the vehicle
speed is 12 km/h (7 mph) or less.
NOTICE
Use “LO” mode when the vehicle is
stopped. Otherwise, when the vehicle
speed exceeds 12 km/h (7 mph), “N”
mode is selected automatically. Prop-
er caution should be taken in places
where the overhead height is limited.
(b) Vehicle height mode changing con- dition
To change the vehicle height, it is neces-
sary to meet the following conditions.
The engine should be running.
The manual control mode indicator light
should go off.

However, when you are driving on bumpy
roads, which may cause the suspension to
fully elongate, the rear height control air
suspension may not operate.
If the vehicle height is adjusted on the
slope, or with the selector lever in a posi-
tion other than “P” or “N” while the vehicle
is stopped, you may hear a sound caused
by the expansion and contraction of the
propeller shaft. This does not indicate a
malfunction.

To raise the vehicle height—
Push the “” side of the switch for two
seconds or more. Each time you push the
switch, the vehicle height increases. When
the vehicle height is about 20 mm (0.8
in.) higher than the standard height, the
“HI” indicator light comes on.
The maximum selectable height is about
40 mm (1.6 in.) higher than the standard
height.
To lower the vehicle height—
Push the “ ” side of the switch. Each
time you push the switch, the vehicle
height decreases.
Tw o −wheel drive models—
When the vehicle height is about 7.5 mm
(0.3 in.) lower than the standard height,
the “LO” indicator light comes on.
The minimum selectable height is about
15 mm (0.6 in.) lower than the standard
height.
Four −wheel drive models—
When the vehicle height is about 15 mm
(0.6 in.) lower than the standard height,
the “LO” indicator light comes on.
The minimum selectable height is about
30 mm (1.2 in.) lower than the standard
height. If the underbody of the vehicle has
touched the surface on bumpy roads, the
vehicle height cannot be lowered with the
height control switch.
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.
If the vehicle height is adjusted on the
slope, or with the selector lever in a posi-
tion other than “P” or “N” while the vehicle
is stopped, you may hear a sound caused
by the expansion and contraction of the
propeller shaft. This does not indicate a
malfunction.
CAUTION
The higher vehicle height should be
only set for severe offroad driving
conditions. Because the vehicle’s cen-
ter of gravity is higher in this setting,
the vehicle may become unstable
when turning abruptly, resulting in an
accident.
NOTICE

When lowering the vehicle, the ve-
hicle must be stopped. Otherwise,
when the vehicle speed exceeds 30
km/h (18 mph), automatic control
mode is activated and “N” is se-
lected automatically. Proper caution
should be taken in places where the
overhead height is limited.
 If the vehicle height is changed fre-
quently when the vehicle is heavily
loaded, the compressor may over-
heat, causing the vehicle height ad-
justment operation to stop.
 Before you lower the vehicle height
with the height control switch,
check under the vehicle to make
sure nothing to damage the vehicle
or no one to be injured is there and
that the underbody of the vehicle
does not touch the ground.
 After unloading, the height of a ve-
hicle equipped with the rear height
control air suspension becomes
slightly higher than the normal ve-
hicle height. Take sufficient care
where the overhead height is re-
stricted.
