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 active trac-
tion control system if the engine speed is
under 3,000 rpm (normally engine speed
is under 3,000 rpm when the wheels get
unstuck).
The four−wheel drive control lever in
the “L” position and the automatic
transmission lever in the “L” position or
the automatic transmission lever in the
“D”, “4”, “3” or “2” with the transmis-
sion downshifting to the first gear
The four −wheel drive control lever in
the “L” position and the automatic
transmission lever in the “R” position
(As for the automatic transmission lever
positions, see “Automatic transmission” on
page 137.)
(b) Shifting procedure
SHIFTING BETWEEN “H” (UNLOCKED)
AND “H” (LOCKED)
To shift between unlock and lock
modes in “H”, push the center differential
lock button.
SHIFTING BETWEEN “L” (UNLOCKED)
AND “L” (LOCKED)
To shift between unlock and lock
modes in “L”, push the center differential
lock button.
SHIFTING BETWEEN “H” AND “L”
Stop the vehicle, put the transmission into
“N” and move the four −wheel drive control
lever.
CAUTION
Never move the four–wheel drive con-
trol lever if wheels are slipping. Wait
until the wheels have stopped slip-
ping or spinning before shifting.
NOTICE
For normal driving on dry and hard
surface roads, unlock the center dif-
ferential. To prevent damage to the
center differential lock system, do not
push the center differential lock but-
ton when the vehicle is cornering or
when its wheels are spinning freely
off the ground. If the indicator light
does not go off when unlocking the
center differential, drive straight
ahead while accelerating or decelerat-
ing, or drive in reverse.

Active traction control system indicator
light
The active traction control system auto-
matically helps control the spinning of
4 wheels which may occur when accel-
erating on slippery road surfaces, by
controlling the output of the brake and
engine. Thus, the system assists driver
to control the driving power of 4
wheels. When you turn the ignition
switch on, the active traction control
system always turns on automatically,
and the active traction control indicator
light will come on. The indicator light
will go off after a few seconds.When active traction control is applied,
the active traction control system indi-
cator light blinks.
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, and does not indicate mal-
function. When the active traction control
system is operating, you may feel vibra-
tion or hear noise of your vehicle, caused
by operation of the brakes. This indicates
the system is functioning properly.
When getting the vehicle out of mud or
newly fallen snow, etc., the active traction
control system will help operate to prevent
the wheels from spinning.Active traction control system failure
warning
This light warns when there is a problem
somewhere in the active traction control
system.
If the “VSC/TRAC” warning light comes
on, have your vehicle checked by your
Toyota dealer as soon as possible.
Active traction control system

145
The brake actuator temperature increases
during the active traction control system
or vehicle stability control system operat-
ing. If the brake actuator temperature be-
comes too high while the active traction
control system or vehicle stability control
system is operating, a buzzer will start to
sound intermittently to indicate that the
active traction control system can no lon-
ger operate. 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 active
traction control system temporarily stops
operating in order to protect the brake
actuator. (Although the active traction con-
trol system does not operate, there is no
problem to continue your driving.) The
system will be automatically restored after
a short time and “VSC/TRAC” warning
light goes off if the accelerator pedal is
released.
When the “ABS” warning light come on,
the active traction control system is not
operating.
The “VSC/TRAC” warning light will come
on when the ignition key is turned “ON”,
and will go off after a few seconds.The “VSC/TRAC” warning light may stay
on for 60 seconds after the ignition key
is turned to “ON” position. It is normal if
it goes off after a few seconds.
Depressing the brake pedal repeatedly
may turn on the “VSC/TRAC” warning
light. It is normal if it goes off after a few
seconds.
When the “VSC/TRAC” warning light
comes on the active traction control sys-
tem is not operating, but there is no prob-
lem if you continue to drive.
In the following cases, contact your Toyota
dealer:
The “VSC/TRAC” warning light does not
come on after the ignition key is turned
“ON”.
The “VSC/TRAC” remains on after the
ignition key is turned “ON”.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicles and
power to 4 wheels may not be main-
tained, even though the active trac-
tion control system is in operation.
Do not drive the vehicle under any
speed or maneuvering conditions
which will cause the vehicle to lose
traction. 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 road conditions pres-
ent.

146
The vehicle stability control system
helps provide integrated control of the
systems such as antilock brake, trac-
tion control, engine control, etc. This
system automatically controls the out-
put of the brakes or engine to help
prevent the vehicle from skidding under
adverse conditions.
The system activates when the vehicle
speed is about 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 ve-
hicle stability control system is in the
self−check mode and does not indicate a
malfunction.CAUTION
Active traction control system, ve-
hicle stability control system and
antilock brake system are electron-
ic systems designed to help the
driver maintain control under ad-
verse conditions. They are not a
substitute for safe driving practices.
Factors including speed, road con-
ditions and driver steering input
can all affect whether active trac-
tion control system, vehicle stability
control system and antilock brake
system will be effective in prevent-
ing a loss of control. Always keep
safety driving in mind. If the slip
indicator light flashes, sounding an
alarm, 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 323.)

If the vehicle is going to skid during driv-
ing, the slip indicator light flashes and an
alarm sounds intermittently.
When you turn the ignition switch on, the
slip indicator light will come on. The slip
indicator light will go off after a few sec-
onds.Pushing the center differential lock button
automatically turns the vehicle stability
control system off. At this time, the “VSC
OFF” indicator comes on with the center
differential lock indicator light. (For details,
see “Four−wheel drive system—(a)Four −
wheel drive control” on page 141.)Vehicle stability control system failure
warning
These lights warn when there is a prob-
lem somewhere in the vehicle stability
control system or active traction control
system.
If the “VSC/TRAC” warning light and “VSC
OFF” indicator light come on, have your
vehicle checked by your Toyota dealer as
soon as possible. However, there is no
problem if the “VSC/TRAC” warning light
comes on when the brake actuator tem-
perature becomes high. (For details, see
“Active traction control system” on page
144.)

148
When the “ABS” warning light comes on,
the vehicle stability control system is not
operating.
The “VSC/TRAC” warning light and “VSC
OFF” indicator light will come on when the
ignition key is turned “ON”, and will go off
after a few seconds.
The “VSC/TRAC” warning light and “VSC
OFF” indicator light may stay on for 60
seconds after the ignition key is turned to
“ON” position. It is normal if they go off
after a few seconds.
Depressing the brake pedal repeatedly
may turn on the lights. It is normal if they
go off after a few seconds.
When the “VSC/TRAC” warning light and
“VSC OFF” indicator light come on, the
vehicle stability control system is not op-
erating, but there is no problem if you
continue to drive.
In the following cases, contact your Toyota
dealer:
The “VSC/TRAC” warning light, “VSC
OFF” indicator light and slip indicator
light do not come on after the ignition
key is turned “ON”.
The “VSC/TRAC” warning light and
“VSC OFF” indicator light remain on af-
ter the ignition key is turned “ON”.
The “VSC OFF” indicator light comes
on while driving without pushing the
center differential lock switch.
16C521a
Low tire pressure warning light
The light warns you that the tire infla-
tion pressure is low.
The low tire pressure warning light comes
on when the ignition key is turned to the
“ON” position and goes off after a few
seconds. This means the low tire pres-
sure warning light is operating properly.
If the tire inflation pressure becomes low,
the light comes on again.If the low tire pressure warning light does
not go off or comes on during driving, it
indicates that tire inflation pressure is low.
Make sure there is no flat tire. If the
light comes on again even after tire infla-
tion pressure adjustment, you may have a
flat tire. If there is not adequate air
pressure in the tires, the light will not go
off.
The light may turn on due to natural
causes such as natural air leaks or tire
inflation pressure changes caused by tem-
perature. In this case, adjusting the tire
inflation pressure will turn off the light.
The tire pressure warning system is not
a substitute for checking tire inflation
pressure.
For details about adjusting the tire
inflation pressure, see “Checking tire
inflation pressure” on page 320.
If the low tire pressure warning light
comes on, the action you must take is
different depending on the type of tires
used.
Tire pressure warning system—

149
Stop your vehicle at a safe place as soon
as possible and check that the tire infla-
tion pressure is as specified on the tire
and loading information label. If the low
tire pressure warning light comes on even
after tire inflation pressure adjustment, it
is probable that you have a flat tire. If
the tire goes flat, change to the spare
tire. (See page 275.)
The spare tire is not equipped with the
tire pressure sensor. So, the low tire
pressure warning light remains on even if
the spare tire is mounted.
The light goes off a few minutes after air
is put into the deflated tire.CAUTION
If the low tire pressure warning light
comes on, observe the following in-
structions:
Decelerate as soon as possible to
the most appropriate speed that
conditions permit.
Avoid abrupt steering wheel maneu-
vering and braking. If the vehicle
tires deteriorate, you could lose
control of the steering wheel or the
brakes, causing death or serious in-
jury.
The warning system may not acti-
vate immediately if bursts or sud-
den air leakage should occur.
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacture on the vehicle placard or
tire inflation pressure label. (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure la-
bel, you should consult the appropri-
ate section of the owner ’s manual to
determine the proper tire inflation
pressure.) When the low tire pressure
telltale is illuminated, one or more of
your tires is significantly underin-
flated. You should stop and check
your tires as soon as possible, and
inflate them to the proper pressure as
indicated on the vehicle’s tire infor-
mation placard. Driving on a signifi-
cantly underinflated tire causes the
tire to overheat and can lead to tire
failure. Underinflation also reduces
fuel efficiency and tire tread life, and
may affect the vehicle’s handling and
stopping ability.

150
Your vehicle has also been equipped
with a TPMS malfunction telltale to
indicate when the system is not oper-
ating properly. When the malfunction
telltale is illuminated, the system may
not be able to detect or signal low
tire pressure as intended. TPMS mal-
function may occur for a variety of
reasons, including the installation of
incompatible replacement tires on the
vehicle. Always check the TPMS mal-
function telltale after replacing one or
more tires on your vehicle to ensure
that the replacement tires are compat-
ible with the TPMS.NOTICE
Do not use liquid sealants for a flat
tire as tire pressure sensors will be
damaged.
 When the tires must be repaired or
replaced, have them repaired or re-
placed by the nearest Toyota dealer
or authorized tire dealer. The tire
pressure sensors will be affected
by the installation or removal of
tires.
 The tire pressure warning system is
not to be used as a substitute for
regular inspections. Be sure to
check the air pressure in the tires
on a regular basis.
 When the tires must be replaced,
replace the grommets for tire pres-
sure sensors as well.
 Tire inflation pressure should be
adjusted for all 5 tires (including a
spare tire).
Warning tends to turn on when
driving at lower outside tempera-
ture, such as in winter, because tire
inflation pressure will be decreased
due to the low temperature. In this
case, after adjustment and initializa-
tion, leave the ignition on for about
20 minutes and increase the tire
inflation pressure by 20 to 30 kPa.
