Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to “ACC” or
“LOCK” position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state emis-
sion inspection if the malfunction indicator
lamp remains on. Contact your Toyota
dealer to check your vehicle’s emission
control system and OBD (OnBoard Diag-
nostics) system before taking your vehicle
for the inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” in Section 6.
(f) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.(g) SRS Warning Light
This light will come on when the igni-
tion key is turned to the ”ACC” or
”ON” position. After about 6 seconds,
the light will go off. This means the
system of the airbag and front seat belt
pretensioners are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, front seat belt pretensioner assem-
blies, inflators, warning light,
interconnecting wiring and power sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.
The light does not come on when the
ignition key is turned to the ”ACC” or
”ON” position or remains on.
The light comes on or flashes while
driving.
(h) ”ABS” Warning Light
The light comes on when the ignition
key is turned to the “ON” position. If
the antilock brake system and the
brake assist system work properly, the
light turns off after a few seconds.
Thereafter, if either of the systems mal-
functions, the light comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
antilock brake system, the brake assist
system, the vehicle skid control system
and/or active traction control system do/
does not operate, but the brake system
still operates conventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
antilock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces.
If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the parts monitored by the
warning light system. Contact your
Toyota dealer as soon as possible to
service the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or remains on.

The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
Either of the following conditions may
occur, but do not indicate the malfunc-
tion.
The light may stay on for about 60
seconds after the ignition key is turned
to “ON” position. It is normal if it turns
off after a while.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
turns off after a few seconds. (i) Open Door Warning Light
This light remains on until all the side
doors and back door are completely
closed.
(j) Unengaged ”Park” Warning Light
This light warns that the transmission
”Park” mechanism is not engaged. If the
fourwheel drive control is in the ”N” posi-
tion while the selector lever is in the ”P”
position, the transmission will disengage
and the wheels will not lock.
CAUTION
To restore the park function, shift the
fourwheel drive control out of ”N”,
or the vehicle can move.
(k) Automatic Transmission Fluid Tem-
perature Warning Light
This light warns that the automatic trans-
mission fluid temperature is too high. If this light comes on while you are driv-
ing, slow down and pull off the road. Stop
the vehicle at a safe place and put the
selector lever in ”P” and leave the engine
idling until the light goes off. If the light
goes off, you can start the vehicle again.
If the light does not go off, call a Toyota
dealer or qualified repair shop for assis-
tance.
NOTICE
Continued driving with the warning
light on may damage the automatic
transmission.
(l) Vehicle Skid Control System and
Active Traction Control System
Warning Light
This light warns that there is a problem
somewhere in the vehicle skid control sys-
tem and/or active traction control system.
If the “VSC/TRAC” warning light and “VSC
OFF” indicator light come on, have your
vehicle checked by Toyota dealer as soon
as possible. However, it is no problem
that the “VSC/TRAC” warning light comes
on when the brake actuator temperature
becomes high. (For details, see “Active
traction control system” in Section 16.)

The lights will come on with the ignition
key turned to “ON”, and will go off after
a few seconds.
The lights may come on for 60 seconds
after the ignition key is turned to “ON”
position. It is normal if they go out after
a while.
Depressing the brake pedal repeatedly
may turn on the lights. it is normal if they
go out after a few seconds.
When the “VSC/TRAC” warning light and
“VSC OFF” indicator light come on, the
vehicle skid control system and/or active
traction control system are not operating,
but there is no problem if you continue to
drive.
(m) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver ’s door with
the ignition key in the ”ACC” or ”LOCK”
position.

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 skid control system is
automatically turned off and the center dif-
ferential lock and “VSC OFF” 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 “VSC OFF”
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 the center differential lock
indicator light and vehicle skid con-
trol system off indicator light turn off.
“H” (high speed position, center differ-
ential unlocked): Lever at “H”, center dif-
ferential lock button left out
Use this for normal driving on all types of
roads, from dry hardsurfaced roads to
wet, icy or snowcovered roads. This
position gives greater economy, quietest
ride, least wear and better vehicle control. “H” (high speed position, center differ-
ential locked):
Lever at “H”, center differ-
ential lock button pushed in
Use this for greater traction when you
experience a loss of power, such as
wheel slipping, in the center differential
unlock mode.
“N” (neutral position): Lever at “N”
No power is delivered to the wheels. The
vehicle must be stopped.
“L” (low speed position, center differen-
tial unlocked): Lever at “L”, center differ-
ential lock button left out
Use this for maximum power and traction.
Use this for climbing or descending steep
hills, offroad 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
“L” (low position, center differential locked)
mode. “L” (low speed position, center differen-
tial locked):
Lever at “L”, center differen-
tial lock button pushed in.
Use this for maximum power and traction.
Use this for hard pulling in situations the
vehicle cannot negotiate even in the “L”
(low speed position, center differential un
locked) mode. Also, using this mode when
driving down steep offroad inclines will
help contribute to increased vehicle stabil-
ity.
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.
If the indicator light does not go off when
you push out the center differential lock
button, drive straight ahead while acceler-
ating or decelerating, or drive in reverse.
See “(b) Shifting procedure” for further in-
structions.

Advice for driving on slippery roads in
“L” (low speed position) mode
If you shift the fourwheel drive control
lever to “L” and the automatic transmis-
sion lever to “2” when you drive in steep
offroad 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 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 fourwheel drive control lever in
the “L” position and the automatic
transmission lever in the “L” position or
the automatic transmission lever in the
“D” or “2” with the transmission down-
shifting to the first gear
The fourwheel 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” in
this section.)
(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 fourwheel 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.

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
is started. This means that the active
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 noise of your vehicle, caused by
operation of the brakes. This indicates the
system is functioning pr
operly.
When getting the vehicle out of mud or
new 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.

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 traction
control system temporarily stops operating
in order to protect the brake actuator. (Al-
though the active traction control 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.

The vehicle skid control system helps
provide comprehensive control of sys-
tems such as antilock brake, traction
control, engine control, etc. This sys-
tem automatically controls the output of
the brakes or engine to help prevent
the vehicle from skidding under adverse
conditions.
The vehicle skid control system activates
when the vehicle speed is more than the
following speed.

. . . . . . . . . . . . . . . . . . . . . . .
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
is started. This means that the vehicle
skid control is in the selfcheck mode and
does not indicate a malfunciton.CAUTION
Active traction control system, ve-
hicle skid control system and anti-
lock brake system are electronic
systems designed to help the driver
maintain control under adverse con-
ditions. They are not a substitute
for safe driving practices. Factors
including speed, road conditions
and driver steering input can all af-
fect whether active traction control
system, vehicle skid control system
and antilock brake system will be
effective in preventing 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 skid control sys-
tem may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” in
Section 72.)
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.
