(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 (without ve-hicle stability control system)
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
anti −lock brake system does not operate,
but the brake system still operates con-
ventionally.
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
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 the light remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
With rear differential lock: However, it is
a normal operation for the light to be on
with rear differential locked. At this time,
the anti −lock brake system does not oper-
ate.
“ABS” Warning Light (with vehicle
stability control system)
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
“AUTO LSD” system
Vehicle stability 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.

“N” (neutral position): Lever at “N”
No power is delivered to the wheels. The
vehicle must be stopped.
“L4” (low speed position, fourwheel
drive): Lever at “L4”
Use this for maximum power and traction.
Use “L4” for climbing or descending steep
hills, off −road driving, and hard pulling in
sand, mud or deep snow.
The four −wheel drive indicator light comes
on when the “H4”, “N” or “L4” mode is
selected.
See “(c) Shifting procedure (lever/button
type)” for further instructions. 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. SHIFTING BETWEEN “H2” AND “H4”
To shift from “H2” to “H4”,
reduce your
speed to less than 80 km/h (50 mph) and
move the front drive control lever. You
need not depress the clutch pedal.
If you have trouble shifting in cold weath-
er, reduce your speed or stop the vehicle
and reshift.
CAUTION
Never move the front drive control
lever if wheels are slipping. Stop the
slipping or spinning before shifting.
To shift from “H4” to “H2”, simply move
the front drive control lever.
This can be done at any vehicle speed.
You need not depress the clutch pedal.
If the indicator light does not go off when
you shift the transfer into “H2”, drive
straight ahead while accelerating or decel-
erating, or drive in reverse.

disconnecting differential) (c) Shifting procedure (lever

“VSC TRAC” warning light
This light warns that when there is a
problem somewhere in the following.
Vehicle stability control system
Traction control system
“AUTO LSD” system
The light will come on when the ignition
key is turned to “ON”, and will go off after
about a few seconds.
The light may come on for 60 seconds
after the ignition key is turned to “ON”. It
is normal if they go out after a while. Depressing the brake pedal repeatedly
may turn on the light. It is normal if they
go out after a few seconds.
If the light comes on while driving, the
vehicle stability control system does not
work. However, as the brakes operate nor-
mally when applied, it is no problem to
continue 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 rear differential lock system is pro-
vided for use only when wheel spinning
occurs in a ditch or on a slippery or
ragged surface.
This differential lock system is effective in
case one of the rear wheels is spinning.
Except for Pre Runner models—
Before using the rear differential lock sys-
tem, first shift the front drive control into
“L4” to see if it works. If this has no
effect, additionally use the rear differential
lock system.

CAUTION
Do not use the rear differential lock
in the conditions other than above.
Large steering effort and careful cor-
nering control will be required.
To lock the rear differential, push the
switch.
Be sure to stop the wheels before locking
the differential.
For easy locking, depress the clutch ped-
al, push the lock switch and slowly re-
lease the clutch pedal.
The indicator light will blink when the
switch is turned on. Wait a few seconds
for the system to complete operation. Af-
ter the differential is locked, the light will
stop blinking and remain on.
The anti−lock brake system does not oper-
ate when the rear differential is locked. It
is normal operation for the “ABS” warning
light to be on at this time.
CAUTION
Do not lock the differential until the
wheels have stopped spinning.
Otherwise, the vehicle may move in
an unexpected direction when the
differential lock is engaged, result-
ing in an accident. This may also
lead to possible damage to differen-
tial lock component parts.
Do not drive over 8 km/h (5 mph)
when the differential is locked.
To unlock the differential, push the
switch once again.
Unlock the differential as soon as the ve-
hicle moves out.
For easy unlocking, slightly turn the steer-
ing wheel in either direction while the ve-
hicle is in motion.
When the differential lock is disengaged,
the indicator light will go out.
Except for Pre Runner models—
The differential will also unlock if you shift
the front drive control lever out of “L4”.
Never forget to turn off the switch after
using this feature.
