Advice for driving on slippery roads in
“L4” (low speed position) mode
If you shift the front drive control lever to
“L4” and the automatic transmission lever
to “D” or “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.
To control the output of the brake effec-
tively, observe the following directions;
In the case of uphill driving with the
front drive control lever positioned in
“L4” and the transmission shift lever
positioned in “L”, make sure the center
differential lock indicator comes on with
your vehicle placed at the level.
When the center differential lock indica-
tor flashes after operating the front
drive control lever, “4WD” switch or the
transmission shift lever, drive straight
ahead while accelerating or decelerat-
ing, or drive in reverse.The A.D.D. can be engaged or disen-
gaged by the shifting operations des-
cribed in “(c) Shifting procedure”.
You should drive in fourwheel drive for
at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated.
SHIFTING BETWEEN “H” (2WD) MODE
AND “H” (4WD) MODE
To shift from “H” (2WD) mode to “H”
(4WD) mode,
reduce your speed to less
than 100 km/h (62 mph) and push in the
“4WD” switch.
If the indicator light flashes when you
push in the “4WD” switch, drive straight
ahead while accelerating or decelerating.
If the indicator light flashes and the buzz-
er sounds when you push in the “4WD”
switch, reduce your speed or stop the
vehicle.
CAUTION
Never push the “4WD” switch if
wheels are slipping. Stop the slipping
or spinning before shifting.
To shift from “H” (4WD) mode to “H”
(2WD) mode, push the “4WD” switch
again to turn it off.
This can be done at any vehicle speed.
If the indicator light flashes when you
push in the “4WD” switch, drive straight
ahead while accelerating or decelerating,
or drive in reverse.

SHIFTING BETWEEN “L4” (UNLOCKED)
AND “L4” (LOCKED)
To shift between unlock and lock
modes in “L4”, move the transmission
shift lever and front drive control lever.
This can be done at any vehicle speed.
If the indicator light flashes when you
move the front drive control lever, drive
straight ahead while accelerating or decel-
erating.
CAUTION
Never move the front drive control
lever if wheels are slipping. Stop the
slipping or spinning before shifting.
NOTICE
Do not drive on a dry paved surface
in “L4” (LOCKED) mode. This may
damage the locking mechanism and
the drive system.
SHIFTING BETWEEN “H” AND “L4”
If the front drive control lever is shifted
from “L4” to “H”, the mode will be “H”
(4WD).
Stop the vehicle and put the transmission
in “N”. With your foot holding down the
brake pedal, move the front drive control
lever.
If the indicator light flashes when you
move the front drive control lever or auto-
matic transmission lever, drive straight
ahead while accelerating or decelerating.
CAUTION
Never move the front drive control
lever if wheels are slipping. Stop the
slipping or spinning before shifting.
NOTICE
Do not drive on a dry paved surface
in “L4” (LOCKED) mode. This may
damage the locking mechanism and
the drive system.
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 ignition key is turned to “ON”,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against 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.

nary 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
is started. This means that the traction
control system is in the selfcheck 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.
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 ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.
TRACTION CONTROL OFF MODE
If your wheels get stuck in a ditch
when you are driving on a severe off
road and sand, turn off the traction
control system. This system that con-
trols engine performance interferes with
the process of freeing your wheels.

This light warns that there is a problem
somewhere in the traction control system
or the vehicle skid control system.
The light will come on when the ignition
key is turned to “ON” and will go off after
a few seconds.The brake actuator temperature increases
during continuous operation of the traction
control system or vehicle skid control sys-
tem such as on slippery roads. If the
brake actuator temperature becomes too
high while the traction control system or
vehicle skid control system is operating,
a buzzer will start to sound intermittently
to indicate that the traction control system
can no longer operate. In this case, imme-
diately 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 sys-
tem 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 warning
light goes out.
If the light comes on while driving, the
traction control system does not work.
However, as conventional braking operates
when applied, there is no problem to con-
tinue your driving.

Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.
The cruise control allows you to cruise
the vehicle at a desired speed over 40
km/h (25 mph) even with your foot off
the accelerator pedal.
Your cruising speed can be maintained up
or down grades within the limits of engine
performance, although a slight speed
change may occur when driving up or
down the grades. On steeper hills, a
greater speed change will occur so it is
better to drive without the cruise control.
CAUTION
To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snowcovered) or
winding roads.
Avoid vehicle speed increases when
driving downhill. If the vehicle
speed is too fast in relation to the
cruise control set speed, cancel the
cruise control then downshift the
transmission to use engine braking
to slow down.
TURNING ON THE SYSTEM
To operate the cruise control, press the
“CRUISE ONOFF” button. This turns the
system on. The indicator light in the
instrument panel shows that you can now
set the vehicle at a desired cruising
speed. Another press will turn the system
