Use the four−wheel drive control switch
knob and center differential lock switch
to select the transfer and center differ-
ential modes.
The H4" and L4" positions of the four−
wheel drive control switch knob provide
either lock or unlock mode of the center
differential. The center differential can be
locked or unlocked by pushing the center
differential lock switch.
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 stability control system
is automatically turned off and the center
differential 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 that the center differential
lock indicator and VSC OFF" indica-
tor lights turn off.

differential unlocked: Four−wheel drive
control switch knob at H4", center differ-
ential unlocked
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.
H4" (high speed position) and center
differential locked: Four−wheel drive con-
trol switch knob at H4", center differential
locked
Use this for greater traction when you
experience a loss of power, such as
wheel slipping, in the center differential
unlock mode. L4" (low speed position) and center
differential unlocked:

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
L4" (low speed position) and center differ-
ential locked mode.
L4" (low speed position) and center
differential locked: Four−wheel drive con-
trol switch knob at L4", center differential
locked

NORMAL DRIVING MODE
Leave the system on during ordinary
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.

control system, the AUTO LSD" system,
the vehicle stability control system and
the hill−start assist control system such
as on slippery roads.
If the brake actuator temperature becomes
too high while any of the systems is oper-
ating, a buzzer will start to sound intermit-
tently to indicate that the traction control
system can no l onger 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 slip indicator light will
come on and the traction control system
temporarily stops operating in order to
protect the brake actuator. (Although the
traction 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 slip indi-
cator light goes out.

AUTO LSD" system
Vehicle stability control system
Hill−start assist control system
When the system is normal and the en-
gine switch 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 warning
light may stay on for 60 seconds after the
engine switch 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 OFF" warning light flashes
while driving, the traction control system
does not work. However, as normal brak-
ing operates when being applied, there is
no problem to continue your driving.
In the following cases, contact your Toyota
dealer:

accelerated on slippery road surfaces.
When the engine switch is turned to ON",
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power to the 4 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,
