When you drive for about 8000 km (5000
miles) after the engine oil replacement,
this light illuminates for about 3 seconds
and then flashes for about 12 seconds
with the ignition key turned to “ON” posi-
tion. If you continue driving without the
engine oil replacement, and if the driving
range exceeds 12000 km (7500 miles), the
light will come on after the ignition key is
turned to “ON” position. The light will re-
main on thereafter.
If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road condition. If the light comes on, re-
place it as soon as possible.
You need to reset the light after the en-
gine oil replacement. Reset the light by
following the procedure below:
1. Turn the ignition key to the “OFF” posi- tion with the odometer reading shown.
(For details, see “Odometer and two
trip meters” on page 116 in this Sec-
tion.)
2. Turn the ignition key to the “ON” posi- tion while holding down the trip meter
reset button. Hold down the button until the light goes
off. Before the light goes off, it illuminates
for 3 seconds, flashes for 2 seconds and
illuminates for 1 sec
ond.
If the system fails to reset, the light will
remain flashing.
(i) “ABS” Warning Light
The light comes on when the ignition key
is turned to the “ON” position. If the anti
lock brake system and the brake assist
system work properly, the light turns off
after a few seconds. Thereafter, if either
of the systems malfunctions, the light
comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
following systems do not operate, but the
brake system still operates conventionally.
Anti lock brake system
Brake assist system
Traction control system
(two wheel drive models)
Active traction control system
(four wheel drive models)
Vehicle stability control system
Downhill assist control system
(four wheel drive models)
Hill start assist control system 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 will 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 dri-
ving.
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 anti lock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
Either of the following conditions may
occur, but do not indicate a malfunc-
tion:
The light may stay on for about 60
seconds after the ignition key is turned
to the “ON” position. It is normal if it
turns off after a while.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
turns off after a few seconds. (j) “VSC TRAC” Warning Light
The light warns that there is a problem
somewhere in the following.
Vehicle stability control system
Traction control system
(two wheel drive models)
Active traction control system
(four wheel drive models)
Downhill assist control system
(four wheel drive models)
Hill start assist control system
The light will come on when the ignition
key turned to “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
ignition key is turned to the “ON” position.
Depressing the brake pedal repeatedly
may turn on the lights. It is normal if they
go out after a few seconds.
There is no problem when the “VSC
TRAC” warning light comes on when the
brake actuator temperature becomes high. If the light comes on while driving, the
above mentioned systems do not work.
However, as conventional braking operates
when applied, there is no problem to con-
tinue your driving.
In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.
The “TRAC OFF” indicator light will come
on when the “VSC TRAC” warning light
comes on even if the “TRAC OFF” switch
is not pushed.
(k) Open Door Warning Light
This light remains on until all the side
doors and back door are completely
closed.

Four wheel drive control switch knob
Center differential lock switch
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 depending on the center differ-
ential lock switch position.
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 light and vehicle stabil-
ity control system off indicator light
turn off.
“H4” (high speed position, center differ-
ential unlocked): Four wheel drive control
switch knob at “H4”, center differential
lock switch 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.
“H4” (high speed position, center differ-
ential locked): Four wheel drive control
switch knob at “H4”, center differential
lock switch pushed in
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, center differ-
ential unlocked): Four wheel drive control
switch knob at “L4”, center differential lock
switch left out
The “4LO” (low speed four wheel drive)
indicator light comes on when the “L4”
mode is selected.
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
“L4” (low position, center differential
locked) mode.
“L4” (low speed position, center differ-
ential locked): Four wheel drive control
switch knob at “L4”, center differential lock
switch pushed in
The “4LO” (low speed four wheel drive)
indicator light comes on when the “L4”
mode is selected. 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, 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.
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 164 in Section 1 6.
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 “(b) Shifting procedure” for further in-
structions.Advice for driving on slippery roads in
“L4” (low speed position) mode
If the four wheel drive control switch knob
is in the “L4” and the automatic transmis-
sion selector lever is in the “2” or “3”
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 selector 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 traction control system if the engine
speed is under 3000 rpm (normally engine
speed is under 3000 rpm when the wheels
get unstuck).

Advice for driving on slippery roads in
“L4” (low speed position) mode
If the multi mode control switch knob is
in the “L4” and the automatic transmission
selector lever is in the “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 as-
sists the driver to control the driving pow-
er of 4 wheels.
Use the “L” position of the automatic
transmission selector 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 traction control system if the engine
speed is under 3000 rpm (normally engine
speed is under 3000 rpm when the wheels
get unstuck).

(As for the automatic transmission selec-
tor lever positions, see “Automatic trans-
mission (4 speed)” on page 134 in this
Section.) 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.
