Use this for maximum power and traction.
Use this for hard pulling in situations the
vehicle cannot negotiate even in the L4"
(low speed position, four−wheel drive) and
center differential unlocked mode. Also,
using this mode when driving down steep
off−road inclines will help contribute to in-
creased vehicle stability.
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 the center
differential lock switch to unlock the cen-
ter differential, drive straight ahead while
accelerating or decelerating, or drive in
reverse.
If the center differential lock system op-
eration 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 203 in Section 1−7.
If the indicator blinks even if doing so,
contact your Toyota dealer as soon as
possible. There may be a trouble in the
center differential lock system.See (c) Shifting procedure" for further in-
structions.
The A.D.D. can be engaged or disen-
gaged by the shifting operations de-
scribed in (c) Shifting procedure".
You should drive in four−wheel drive for
at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated.

reduce the vehicle speed to less than 100
km/h (62 mph) and turn the multi−mode
control switch knob fully clockwise.
If the four−wheel drive indicator light con-
tinues to blink when you operate the mul-
ti−mode control switch knob from the H2"
to the H4" position, this reminds you that
the transfer mode is not securely in H4"
mode. Drive straight ahead while acceler-
ating or decelerating.
If the four−wheel drive indicator and the
center differential lock indicator lights con-
tinue to blink and the buzzer sounds when
you operate the multi−mode control switch
knob from the H2" to the H4" position,
this reminds you that the vehicle speed is
above 100 km/h (62 mph). Reduce the
vehicle speed to less than 100 km/h (62
mph). Operate the switch knob again.To shift from H4" (unlocked) to H2",
turn the multi−mode control switch knob
fully counterclockwise.
This can be done at any speed.
If the four−wheel drive indicator light con-
tinues to blink when you operate the mul-
ti−mode control switch knob from the H4"
to the H2" position, this reminds you that
the transfer mode is not securely in H2"
mode. Drive straight ahead while acceler-
ating or decelerating, or drive forward or
backward in a short distance.
If the indicator light continues to blink
even if doing so, contact your Toyota
dealer as soon as possible. There may be
a trouble in the four−wheel drive system.

If the 4LO" (low speed four−wheel drive)
indicator light continues to blink and the
buzzer sounds when you operate the mul-
ti−mode control switch knob to the H4" or
L4" position, drive forward or backward in
a short distance, then stop the vehicle
completely, shift the automatic transmis-
sion selector lever securely into N" and

doing so, contact your Toyota dealer as
soon as possible. There may be a trouble
in the four−wheel drive system.
CAUTION
Never operate the multi−mode control
switch knob if the wheels are slip-
ping. Stop the slipping or spinning
before operating.
The traction control system automatical-
ly helps prevent the spinning of rear
wheels when the vehicle is started or
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 rear 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,
your vehicle should be fitted with
snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.

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.

(two−wheel drive models)

176
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
The slip indicator light comes on for a few
seconds when the engine switch is turned
to ON". If the indicator light does not
come on when the engine switch is turned
on, contact your Toyota dealer.
The brake actuator temperature increases
during continuous operation of the traction
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.
CY16075
TRACTION CONTROL OFF MODE

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,

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.
NOTICE
Do not use the AUTO LSD" system
in conditions other than the above. A
much greater steering effort and more
careful cornering control will be re-
quired.
