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 “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.
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 3000 rpm (normally engine speed is
under 3000 rpm when the wheels get un-
stuck).
The front drive control lever in the “L4”
position and the automatic transmission
lever in the “L” position or the automat-
ic transmission lever in the “D” or “2”
with the transmission downshifting to
the first gear
The front drive control lever in the “L4”
position and the automatic transmission
lever in the “R” position(As for the automatic transmission lever
positions, see “Automatic transmission” in
this section.)The A.D.D. can be engaged or disen-
gaged by the shifting operations des-
cribed 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.

disconnecting differential)

To shift from “H” (4WD LOCKED) to
“H” (4WD UNLOCKED), left out the cen-
ter differential lock switch.
This can be done at any vehicle speed.
If the indicator light flashes when you left
out the center differential lock switch,
drive straight ahead while accelerating or
decelerating, or drive in reverse.
SHIFTING BETWEEN “H” AND “L4”
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, drive
straight ahead while accelerating or decel-
erating.
CAUTION

AND “L4” (LOCKED)
To shift between unlock and lock
modes in “L”, push the center differential
lock switch.
This can be done at any vehicle speed.
If the indicator light flashes when you
push the center differential lock switch,
drive straight ahead while accelerating or
decelerating.
CAUTION

lock switch 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 control the spinning of rear
wheels which may occur when acceler-
ating on slippery road surfaces, by con-
trolling the output of the brake and en-
gine. Thus, the system assists driver to
control the driving power of rear
wheels.
When you turn the ignition switch on, the
traction control system always turns on
automatically, and the slip indicator light
will come on. The indicator lights will go
off after about a few seconds.
If the slip indicator lights is left on after
the ignition is turned on, have your ve-
hicle checked by your Toyota dealer as
soon as possible.

Leave the system on during ordinary driv-
ing so that it can operate when needed.
When traction control is applied, the slip
indicator 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 traction
control system is in the self check mode,
and does not indicate malfunction. When
the traction control system is operating,
you may feel vibration or noise of your
vehicle, caused by operation of the
brakes. This indicates the system is func-
tioning properly.
When getting the vehicle out of mud or
new snow, etc. the traction control system
will help operate to prevent the wheels
from spinning.
You can turn off the traction control
system by pushing the “TRAC OFF”
switch. The “TRAC OFF” indicator light
will come on. Pushing the “TRAC OFF”
switch a second time turns on the trac-
tion control system again and the
“TRAC OFF” indicator light will go off.
The traction control system will automati-
cally go on, and the “TRAC OFF” indicator
light will go off when you drive over 30
km/h (19 mph) even if the “TRAC OFF”
switch is pushed to cancel the traction
control system.If your wheels get stuck in a ditch or
when you are driving on a slippery or
bumpy surface, turn off the traction control
system because its function that controls
engine performance interferes with the
process of freeing your wheels.

Traction control system failure warning
These lights warn that when there is a
problem somewhere in the traction control
system.
If the “TRAC OFF” indicator light and
“VSC/TRAC” warning light come on, have
your vehicle checked by Toyota dealer as
soon as possible.
The lights will come on when the ignition
key is turned to “ON”, and will go off after
about a few seconds.
The lights may come on for 60 seconds
after the ignition key is turned to the “ON”
position. It is normal if they go out after
a while.Depressing the brake pedal repeatedly
may turn on the “TRAC OFF” indicator
light and “VSC/TRAC” warning light. It is
normal if it goes out 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 system tempo-
rarily stops operating in order to protect
the brake actuator. (Although the 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 the “VSC/TRAC” warning
light goes out.When the “VSC/TRAC” warning light and
“TRAC OFF” indicator light come on the
traction control system does not operate,
but there is no problem to continue your
driving.
In the following cases, contact your Toyota
dealer:
The “VSC/TRAC” warning light and
“TRAC OFF” indicator light do not
come on after the ignition is turned to
on.
The “VSC/TRAC” warning light “TRAC
OFF” indicator light are left on after the
ignition is turned to on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power to the rear wheels can not be
maintained, even though the traction
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 ve-
hicle should be fitted with snow tires
or tire chains. Always drive at ap-
propriate and cautious pace.
