“VSC TRAC” warning light
This light warns that there is a problem
somewhere in the following.
Active traction control system
Vehicle stability control system
Downhill assist control system
Hill−start assist control 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 “VSC
TRAC” 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 come on while driving, the
active traction control system does not
work. However, as normal braking oper-
ates when being 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 “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
rough surface.
This system is effective in case one of
the rear wheels is spinning.

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.
This 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” on
page 427 in Section 72.)
If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
If the brake pedal is depressed while the
vehicle stability control system is active,
the brake pedal will become hard at an
earlier position than usual. However, the
brakes will respond to the pedal force if
depressed further.
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.

cator light.
The “VSC 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 center differential lock
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 to
“ON”.

The light will come on when the ignition
key is turned to “ON”, and will go off after
about a few seconds.
The light may come on for 60 seconds
after the ignition key is turned to “ON”. It
is normal if they go out after a while.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if they
go out after a few seconds.
If the “VSC TRAC” waning light and slip
indicator light come on while driving, the
vehicle stability control system does not
work. However, as normal braking oper-
ates when being 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 downhill assist control system is a
system that assists the deceleration of
the engine brake when you drive down
a steep hill. When you are driving down
a hill with the fourwheel drive control
switch knob (fulltime fourwheel drive
models) or multimode control switch
knob (multimode fourwheel drive
models) in the “L4” position, push the
“DAC” switch to limit the vehicle’s ac-
celeration. If the vehicle is traveling at
a speed of 25 km/h (15 mph) or less,
you can descend at a constant speed.
CAUTION
Do not rely excessively on the down-
hill assist control system. It may not
be able to maintain a low speed over
road surfaces or offroad surfaces on
which sliding can easily occur, such
as extremely steep slopes or icy or
muddy roads.
TO ACTIVATE THE DOWNHILL ASSIST
CONTROL SYSTEM
1. Fulltime fourwheel drive models— Turn the fourwheel drive control
switch knob to the “L4” position.
The system will not operate if the four −
wheel drive control switch knob is in the
“H4” position.
Multimode fourwheel drive mod-
els—Turn the multimode control
switch knob to the “L4” position.
The system will not operate if the multi −
mode control switch knob is in the “H4”
position.
2. In order to make full use of the en- gine brake, putting the transmission
in “L” or “2” is recommended.
The system will operate even if the trans-
mission selector lever is in “D”, “4”, “3”
or “N”. However, when it is in “L” or “2”
the engine brake can also be utilized en-
abling the system to operate more effec-
tively.

When the hill−start assist control system
is operating, the slip indicator light flashes
and an alarm sounds intermittently. At the
same time, the stop lights and high
mounted stoplight are lit.
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. Keep in mind the following when driv-
ing.
The hill−
start assist control system op-
erates for 5 seconds maximally. If both
the brake and accelerator pedals re-
main undepressed for longer than 5
seconds, the buzzer will sound at more
frequent intervals and the system will
gradually stop operating.
The hill −start assist control system is
not designed as a function for stopping
the vehicle on a uphill slope. When
stopping the vehicle, be sure to de-
press the brake pedal.
The brake actuator temperature increases
during continuous operation of the downhill
assist control system (four −wheel drive
models), the traction control system (two−
wheel drive models), the active traction
control system (four −wheel drive models),
the vehicle stability control system and
the “AUTO LSD” system (two −wheel drive
models) on such as slippery roads. If the
brake actuator temperature becomes too
high while any of the systems is operat-
ing, a buzzer will start to sound intermit-
tently to indicate that the hill −start assist
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 this time, the slip indicator light will
come on and the hill
−start assist control
system stops operating temporarily in or-
der to protect the brake actuator. (Al-
though the hill −start assist control system
does not operate, it is no problem to con-
tinue your driving.) The system will be
automatically restored after a short time
and the slip indicator light goes out.

This rear height control air suspension
controls the vehicle height depending
on the vehicle driving conditions. Select
your desired height among the “HI”
(high), “N” (normal) and “LO” (low)
modes with the height select 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.

185
“HI” (high) mode—
The vehicle height is about 40 mm (1.6
in.) higher at rear than the “N” mode
height.
This mode is suitable when driving on the
bumpy roads and through water.
However, when the vehicle speed exceeds
about 30 km/h (19 mph) or over in the
“HI” mode, the “N” mode is automatically
selected.
CAUTION
The “HI” mode should be used for
severe offroad driving condition
only. Because the vehicle’s center of
gravity is higher in this setting, the
vehicle may become unstable when
turning abruptly, resulting in accident.
“LO” (low) mode—
The vehicle height is about 20 mm (0.8
in.) lower at rear than the “N” mode
height.
This mode allows you easy access to the
vehicle (getting in and out) and easy load-
ing and unloading operation.
This mode is available when the vehicle
speed is under about 12 km/h (7 mph).
NOTICE
Use the “LO” mode when the vehicle
is stopped. Otherwise, when the ve-
hicle speed exceeds about 12 km/h (7
mph), “N” mode is selected automati-
cally. So be careful when you drive in
any place 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 height control “OFF” indicator light
should go off.
When selecting a mode, there is a ve-
hicle speed limit. Refer to the following
table.
Yes = The mode can be selected.

which mode is selected. (See “(e) Height
control indicator light” described below.)
Selecting the “HI” mode—
Push the height select switch on the “ ”
side when the vehicle speed is under
about 30 km/h (19 mph).
To change the “N” mode to “HI”, push
the switch once. To change the “LO” mode to “HI”,
push
the switch twice. It takes about 30 sec-
onds until the “LO” mode changes to the
“HI” mode.
Selecting the “N” mode—
To change the “HI” mode to “N”, push
the height select switch on the “ ” side
once.
To change the “LO” mode to “N”, push
the height select switch on the “ ” side
once.
Selecting the “LO” mode—
Push the height select switch on the “ ”
side while the vehicle is stopped.
To change the “N” mode to “LO”, push
the switch once.
To change the “HI” mode to “LO”, push
the switch twice.
Even if the engine is stopped while the
vehicle height is being lowered, the opera-
tion continues for up to 25 seconds. If,
within this 25 seconds, any of the side
doors or the back door is opened, opera-
tion will continue for a further 15 seconds.

NOTICE
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 select 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.
 Do not select the “LO” mode in the
bumpy roads. If the underbody of
the vehicle touches the rugged road
surface, the vehicle may be dam-
aged.
(d) Turning off the rear height control
air suspension
To turn off the rear height control air
suspension with the vehicle stopped,
push the “HEIGHT CONTROL OFF”
switch. The height control “OFF” indi-
cator light comes on and the vehicle
height is fixed in the same mode as the
height control switch is pushed.
This status is memorized in the system
even after the engine is stopped.
If you push the switch again, the height
control “OFF” indicator light goes out and
the rear height control air suspension is
turned on.
Even after the rear height control air sus-
pension is turned off with the “HEIGHT
CONTROL OFF” switch, if the vehicle
speed exceeds 30 km/h (19 mph), the
rear height control air suspension automat-
ically selects the “N” mode.

about 700 mm (28 in.) in depth, put
the vehicle height in the “HI” mode
with the height select switch and then
turn off the rear height control air
suspension by pushing the “HEIGHT
CONTROL OFF” switch.
NOTICE
When jacking up or insta lling tire
chains, be sure to turn off the rear
height control air suspension by
pushing the “HEIGHT CONTROL
OFF” switch and stop the engine.
Otherwise, the vehicle height may
change because of the automatic
leveling function, resulting in an un-
expected accident.
 If your vehicle must be towed, put
the vehicle height in the “N” mode
and turn off the rear height control
air suspension. Otherwise, the ve-
hicle height may change because of
the automatic leveling function, re-
sulting in an unexpected accident.
If your vehicle gets ditched, turn off
the rear height control air suspen-
sion with the “HEIGHT CONTROL
OFF” switch. Otherwise, the vehicle
height may change because of the
automatic leveling function resulting
in an unexpected accident.
