Installation of a mobiletwoway radio system
As the installation of a mobile two −way radio system in
your vehicle could affect electronic systems such as
multiport fuel injection system/sequential multiport fuel
injection system, electronic throttle control system,
cruise control system, anti −lock brake system, active
traction control system, vehicle stability control system,
SRS airbag system and seat belt pretensioner system,
be sure to check with your Toyota dealer for precaution-
ary measures or special instructions regarding installa-
tion.
Tires and loading on your Toyota
Underinflated or overinflated tire inflation pressure
and the excess load may result in the deterioration
of steering ability and braking ability, leading to
an accident. Check the tire inflation pressure peri-
odically and be sure to keep the load limits given
in this Owner ’s Manual. For details about tire infla-
tion pressure and load limits, see pages 299 and
229.
Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in
your Toyota contain explosive chemicals. If the vehicle
is scrapped with the airbags and pretensioners left as
they are, this may cause an accident such as fire. Be
sure to have the systems of the SRS airbag and seat
belt pretensioner removed and disposed of by a qualified
service shop or by your Toyota dealer before you dis-
pose of your vehicle.

(h) SRS Warning Light
This light will come on when the igni-
tion key is turned to the “ON” position.
After about 6 seconds, the light will go
off. This means the system of the air-
bag and front seat belt pretensioners
are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors,
driver ’s seat position sensor, driver ’s seat
belt buckle switch, front seat belt preten-
sioner assemblies, inflators, warning light,
roll sensing of curtain shield airbags off
indicator light, interconnecting wiring and
power sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the components monitored by the warning
light system. Contact your Toyota dealer
as soon as possible to service the ve-
hicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on.
The light comes on or flashes while
driving.If the light stays on, it indicates that the
driver and passenger airbags have a prob-
lem. If the light flashes, the side and cur-
tain shield airbags and/or the seat belt
pretensioners have a problem.
(i) “ABS” Warning Light
The light comes on when the ignition
key is turned to the “ON” position. If
the antilock brake system and the
brake assist system work properly, the
light turns off after a few seconds.
Thereafter, if either of the systems mal-
functions, the light comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti
−lock brake system, the brake assist
system, the vehicle stability control sys-
tem and/or active traction control system
do/does not operate, but the brake system
still operates conventionally.
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 could 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 driv-
ing.
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 antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.

2004 L/C100 from Aug ’03 Prod. (OM60A04U)
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 “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) Open Door Warning Light
This light remains on until all the side
doors and back door are completely
closed.
(k) Unengaged “Park” Warning Light
This light warns that the transmission
“Park” mechanism is not engaged. If the
four −wheel drive control is in the “N” posi-
tion while the selector lever is in the “P”
position, the transmission will disengage
and the wheels will not lock.
CAUTION
To restore the park function, shift the
fourwheel drive control out of “N”,
or the vehicle can move.
(l) Automatic Transmission Fluid Tem- perature Warning Light
This light warns that the automatic trans-
mission fluid temperature is too high.
If this light comes on while you are driv-
ing, slow down and pull off the road. Stop
the vehicle at a safe place and put the
selector lever in “P” and leave the engine
idling until the light goes off. If the light
goes off, you can start the vehicle again.
If the light does not go off, call a Toyota
dealer or qualified repair shop for assis-
tance.
NOTICE
Continued driving with the warning
light on may damage the automatic
transmission.
(m) Vehicle Stability Control System and Active Traction Control System
Warning Light
This light warns that there is a problem
somewhere in the vehicle stability control
system and/or active traction control sys-
tem.
If the “VSC/TRAC” warning light and “VSC
OFF” indicator light come on, have your
vehicle checked by Toyota dealer as soon
as possible. However, it is no problem
that the “VSC/TRAC” warning light comes
on when the brake actuator temperature
becomes high. (For details, see “Active
traction control system” on page 149.)
The lights will come on with the ignition
key turned to “ON”, and will go off after
a few seconds.
The lights may come on for 60 seconds
after the ignition key is turned to “ON”
position. It is normal if they go out after
a whi l e.
Depressing the brake pedal repeatedly
may turn on the lights. it is normal if they
go out after a few seconds.

2004 L/C100 from Aug ’03 Prod. (OM60A04U)
When the “VSC/TRAC” warning light and
“VSC OFF” indicator light come on, the
vehicle stability control system and/or ac-
tive traction control system are not operat-
ing, but there is no problem if you contin-
ue to drive.
(n) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver ’s door with
the ignition key in the “ACC” or “LOCK”
position.
CHECKING SERVICE REMINDER INDICA-
TORS (except the low fuel level warning
light)1. Apply the parking brake.

light go off after a few seconds. The
SRS warning light goes off after about
6 seconds.
There may be the case that the “ABS”,
“VSC/TRAC” and “VSC OFF” stay on
for about 60 seconds after the ignition
key is turned to “ON” position. It is
normal if they go out after a while.

“H” (high speed position, center differ-
ential unlocked): Lever at “H”, center dif-
ferential lock button 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.
“H” (high speed position, center differ-
ential locked): Lever at “H”, center differ-
ential lock button pushed in
Use this for greater traction when you
experience a loss of power, such as
wheel slipping, in the center differential
unlock mode.
“N” (neutral position): Lever at “N”
No power is delivered to the wheels. The
vehicle must be stopped.
“L” (low speed position, center differen-
tial unlocked): Lever at “L”, center differ-
ential lock button left out
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
“L” (low position, center differential locked)
mode.
“L” (low speed position, center differen-
tial locked):
Lever at “L”, center differen-
tial lock button pushed in.
Use this for maximum power and traction.
Use this for hard pulling in situations the
vehicle cannot negotiate even in the “L”
(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.
If the indicator light does not go off when
you push out the center differential lock
button, drive straight ahead while acceler-
ating or decelerating, or drive in reverse.
See “(b) Shifting procedure” for further in-
structions. Advice for driving on slippery roads in
“L” (low speed position) mode
If you shift the four
−wheel drive control
lever to “L” and the automatic transmis-
sion 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 3,000 rpm (normally engine speed
is under 3,000 rpm when the wheels get
unstuck).
The four −wheel drive control lever in
the “L” position and the automatic
transmission lever in the “L” position or
the automatic transmission lever in the
“D”, “4”, “3” or “2” with the transmis-
sion downshifting to the first gear

Active traction control system indicator
light
The active traction control system auto-
matically helps control the spinning of
4 wheels which may occur when accel-
erating on slippery road surfaces, by
controlling the output of the brake and
engine. Thus, the system assists driver
to control the driving power of 4
wheels. When you turn the ignition
switch on, the active traction control
system always turns on automatically,
and the active traction control indicator
light will come on. The indicator light
will go off after a few seconds.When active traction control is applied,
the active traction control system indi-
cator 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
begins to move. This means that the ac-
tive traction control system is in the self
−
check mode, and does not indicate mal-
function. When the active traction control
system is operating, you may feel vibra-
tion or hear noise of your vehicle, caused
by operation of the brakes. This indicates
the system is functioning properly.
When getting the vehicle out of mud or
new snow, etc. the active traction control
system will help operate to prevent the
wheels from spinning.Active traction control system failure
warning
This light warns when there is a problem
somewhere in the active traction control
system.
If the “VSC/TRAC” warning light comes
on, have your vehicle checked by your
Toyota dealer as soon as possible.
