Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state
emission inspection if the malfunction
indicator lamp remains on. Contact your
Toyota dealer to check your vehicle’s
emission control system and OBD
(OnBoard Diagnostics) system before
taking your vehicle for the inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” in Section 6.
(g) 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. (h) “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
antilock brake system, the brake assist
system, the traction control system (two
wheel drive vehicles), the active traction
control system (fourwheel drive vehicles)
and the vehicle skid control system do not
operate, but the brake system still oper-
ates conventionally.
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 oc-
curs, this indicates a malfunction some-
where in the parts monitored by the
warning light system. Contact your To-
yota dealer as soon as possible to ser-
vice 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.

Either of the following conditions may
occur, but do not indicate the 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.
(i) “VSC TRAC” Warning Light
The 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 turned to “ON”, and will go off after
a few seconds.
The light 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 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.
(For details, see “Traction control system”
and “Active traction control” in Section
16.)
If the light comes on while driving, the
vehicle skid system and/or traction control
system (twow
heel drive models) or active
traction control system (fourwheel drive
models) do not work. However, as conven-
tional 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.
(j) Open Door Warning Light
This light remains on until all the doors
and back door are completely closed. (k) 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, front seat belt pretensioner assem-
blies, inflators, warning light,
interconnecting 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 “ON” posi-
tion or remains on.
The light comes on or flashes while
driving.
(l) 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.

“H” mode (high speed position, two
wheel drive): Front drive control lever at
“H”, “4WD” button left out
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” button push in, center differential
lock switch left out
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.
“H” mode (high speed position, four
wheel drive, center differential locked):
Lever at “H”, “4WD” button pushed in cen-
ter 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. “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): Front drive control lever at “L4”,
center differential lock switch left out
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.
The transmission automatically shifts up
from second gear in this mode. This sys-
tem is effective when starting your vehicle
in sand, mud, ice or snow. (However, 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):
Front drive control lever at “L4”, center
differential lock switch push in
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.
Fourwheel drive and center differential
lock indicator lights show which transfer
and center differential mode the vehicle is
in. Note that the differential is not still
locked as long as the indicator light re-
mains off.
When the shifting has not been completed
within 3 seconds after the shifting opera-
tion, the indicator flashes. If the indicator
light does not go off when you push out
the center differential lock button, drive
straight ahead while accelerating or decel-
erating, 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 center differential
lock 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 “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.
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 fourwheel drive for
at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated.

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 “L4” (UNLOCKED)
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
Never push the center differential
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 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 to the 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.
