(h) SRS Warning Light
This indicator comes on when the igni-
tion key is turned to the “ON” position.
It goes off after about 6 seconds. This
means the SRS airbags and seat belt
pretensioners are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sensor
assemblies, curtain shield airbag sensor
assemblies, driver ’s seat position sensor,
driver’s seat belt buckle switch, front pas-
senger occupant classification system and
indicator light, front passenger ’s seat belt
buckle switch, seat belt pretensioner as-
semblies, inflators, roll sensing of curtain
shield airbags off indicator light, intercon-
necting wiring and power sources.
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on for more than 6
seconds or flashes.
The light comes on or flashes while
driving.The SRS warning light will come on and
front passenger occupant classification in-
dicator light will indicate “OFF” if there is
a malfunction in the front passenger occu-
pant classification system.
(i) “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
anti
−lock brake system, the brake assist
system, the vehicle stability control sys-
tem 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
anti −lock 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 components 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.

139
(n) Vehicle Stability Control System andActive Traction Control System
Warning Light
This light warns that there is a problem
somewhere in the vehicle stability control
system and/or active traction control sys-
tem.
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” on page 152.)
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 whi l e.
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 stability control system and/or ac-
tive traction control system are not operat-
ing, but there is no problem if you contin-
ue to drive.
(o) Key Reminder Buzzer
This buzzer acts as a reminder to remove
the key when you open the driver’s door
with the ignition key in the “ACC” or
“LOCK” position.
CHECKING SERVICE REMINDER INDICA-
TORS (except the low fuel level warning
light)
1. Apply the parking brake.
2. Open one of the side doors or back door.
The open door warning light should
come on.
3. Close the door. The open door warning light should go
off. 4. Place the four
−wheel drive control lever
in “N” position and the selector lever
in “P” position and turn the ignition key
to “ACC”.
The “A/T P” should come on. It goes
off when you place the four −wheel
drive control lever in “H” or “L” posi-
tion.
5. Turn the ignition key to “ON”, but do not start the engine.
All the service reminder indicators ex-
cept the open door warning light should
come on. The “ABS”, “VSC/TRAC”,
“VSC OFF”, “TRAC”, front passenger
occupant classification indicator light
and slip indicator light go off after a
few seconds. The SRS warning light
goes off after about 6 seconds.
There may be the case that the “ABS”,
“VSC/TRAC” and “VSC OFF” stay on
for about 60 seconds after the ignition
key is turned to “ON” position. It is
normal if they go out after a while.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, have it checked by your Toyota
dealer as soon as possible.

“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 hard −surfaced roads to
wet, icy or snow −covered 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, off −road 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 off −road 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.
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. The center differential lock system opera-
tion 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 164.
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 four
−wheel drive control
lever to “L” and the automatic transmis-
sion 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.

151
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 145.)
(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.

152
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.
