The spark ignition system in your Toyota meets all re-
quirements of the Canadian InterferenceCausing Equip-
ment Standard.
Installation of a mobiletwoway radio system
As the installation of a mobile twoway 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, antilock brake system, traction
control system (fourwheel drive models)/active traction
control system (twowheel drive models), vehicle skid
control system, SRS airbag system and seat belt preten-
sioner system, be sure to check with your Toyota dealer
for precautionary measures or special instructions re-
garding installation.
Scrapping of your Toyota
The SRS airbag and front seat belt pretensioner devices
in your Toyota contain explosive chemicals. If the ve-
hicle 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 dispose of your vehicle.

Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to “ACC” or
“LOCK” position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
Emissions inspection and maintenance
(I/M) programs
We recommend you to contact your
Toyota dealer to check your vehicle’s
emission control system and OBD
(OnBoard Diagnostics) system before
taking your vehicle for a state emission
inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” on page 276
in Section 6.(f) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.
(g) “ABS” Warning Light
The light comes on when the ignition key
is turned to the “ON” position. If the anti
lock brake system works properly, the
light turns off after a few seconds. There-
after, if the system malfunctions, the light
comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
antilock brake system, the traction con-
trol system (twowheel drive vehicles), the
active traction control system (fourwheel
drive vehicles) and the vehicle skid con-
trol system do not operate, but the brake
system still operates conventi
onally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
antilock 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
occurs, this indicates a malfunction
somewhere in the parts 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 antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.

1292002 MY SEQUOIA_U (OM34418U)
(h) “VSC/TRAC” Warning Light
This light warns that there is a problem
somewhere in the vehicle skid control sys-
tem and traction control system (two
wheel drive models) or active traction con-
trol system (fourwheel drive models).
The light will come on when the ignition
key is turned to “ON” and will go off after
a few seconds.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.
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.(i) Open Door Warning Light
This light remains on until all the side
doors and back door are completely
closed.
(j) 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 pretensioner are
operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, front seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts 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 “ACC” or
“ON” position or remains on.
The light comes on or flashes while
driving.(k) 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.
(l) Unengaged “Park” Warning Light
This light warns that the transmission
“Park” mechanism is not engaged. If the
front drive control lever 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
front drive control lever out of “N”,
or the vehicle can move.

Use the transmission shift lever, front
drive control lever and “4WD” switch to
select the transfer and center differen-
tial modes.
The “H” and “L4” position of the front
drive control lever and the “L” position of
the transmission shift lever provide either
lock or unlock the mode of the center
differential.
“H” mode (high speed position, two
wheel drive): Front drive control lever at
“H”
Use this for normal driving on dry hard
surfaced roads. This position gives greater
economy, quietest ride and least wear and
better vehicle control.
“H” mode (high speed position, four
wheel drive, center differential un-
locked): Front drive control lever at “H”,
“4WD” switch pushed once
Use this for normal driving on all types of
roads, from dry hardsurfaced roads to
wet, icy or snowcovered roads. This
position provides greater traction than
twowheel drive.
“N” mode (neutral position): Front drive
control lever at “N”
No power is delivered to the wheels. The
vehicle must be stopped. “L4” mode (low speed position, four
wheel drive, center differential un-
locked):
Transmission shift lever except
at “L”, front drive control lever at “L4”
Use this for maximum power and traction.
Use this for climbing steep hills, offroad
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, fourwheel drive, center
differential locked) mode.
If you place the transmission shift lever at
“2” in this mode, the transmission auto-
matically shifts up from second gear. This
system is effective when starting your ve-
hicle in sand, mud, ice or snow. (Howev-
er, the transmission system may shift up
from first gear when the vehicle starts too
quickly.) “L4” mode (low speed position, four
wheel drive, center differential locked):
Transmission shift lever at “L”, front drive
control lever at “L4”
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, fourwheel drive, cen-
ter differential unlocked) mode. Also, using
this mode when driving down steep off
road inclines will help contribute to in-
creased vehicle stability.
The indicator shows which transfer and
center differential mode the vehicle is in.
When the shifting operation has not been
completed after moving the lever, the
indicator flashes. If the indicator light does
not go off when you move the transmis-
sion shift lever and/or front drive control
lever, drive straight ahead while accelerat-
ing or decelerating, or drive in reverse. If
the indicator flashes even if doing so,
contact your Toyota dealer as soon as
possible. There may be a trouble in the
four wheel drive system.
See “(c) Shifting procedure” for further in-
structions.

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.

NORMAL DRIVING MODE
Leave the system on during the ordi-
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.
To turn off: Push “TRAC OFF” switch.
The “TRAC OFF” indicator light will come
on.
To turn on: Push “TRAC OFF” switch
once again.
The “TRAC OFF” indicator light will go off.
