Use the “2WD/4HI” and “4LO” buttons
to select the following transfer modes.
1. “2WD” (high speed position, two wheel drive): “2WD/4HI” and “4LO”
buttons left out
Use this for normal driving on dry,
hardsurfaced roads. This position
gives greater economy, the quietest
ride and least wear.
2. “4HI” (high speed position, four wheel drive): “2WD/4HI” button pushed
in
The “4HI” (high speed fourwheel
drive) indicator light comes on when
the “4HI” mode is selected.
Use this for normal driving on wet, icy
or snowcovered roads. This position
provides greater traction than two
wheel drive.
3. “4LO” (low speed position, four wheel drive): With the “2WD/4HI”
button pressed in, push the “4LO”
button
The “4LO” (low speed fourwheel drive)
indicator light comes on when the
“4LO” mode is selected.
Use this for maximum power and trac-
tion. Use “4LO” mode for climbing or
descending steep h ills, offroad driving,
and hard pulling in s and, mud or deep
snow. See “(c) Shifting procedure (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 fourwheel drive for
at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated.

The rear step bumper is for rear end
protection and easier stepup loading.
CAUTION
Do not allow more than one person
to get on the rear step bumper at
a time. It is designed for only one
person.
Never drive the vehicle with anyone
on the rear step bumper.
Some Toyotas are equipped with a lim-
itedslip differential. If one of the rear
wheels begins to spin, the limitedslip dif-
ferential is designed to aid traction by
automatically transmitting driving force to
the other rear wheel. If you are not sure
whether your vehicle is equipped with one,
you can ask your Toyota dealer.
CAUTION
Do not start or run the engine while
your vehicle is supported by a jack.
The vehicle could be driven off the
jack and could pose a danger or re-
sult in serious injury.
NOTICE
Use only a spare tire of the same
size, construction and load capacity
as the original tires on your Toyota
because damage to the limitedslip
differential could possibly occur with
another tire type.
The vehicle identification number (VIN)
is the legal identifier for your vehicle.
This number is on the left top of the
instrument panel, and can be seen
through the windshield from outside.
This is the primary identification number
for your Toyota. It is used in registering
the ownership of your vehicle.

Land Management
CAUTION
Always observe the following precau-
tions to minimize the risk of serious
personal injury or damage to your ve-
hicle:
Drive carefully when off the road.
Do not take unnecessary risks by
driving in dangerous places.
Do not grip the steering wheel
spokes when driving offroad. A
bad bump could jerk the wheel and
injure your hands. Keep both hands
and especially your thumbs on the
outside of the rim.
Always check your brakes for effec-
tiveness immediately after driving in
sand, mud, water or snow.
After driving through tall grass,
mud, rock, sand, rivers, etc., check
that there is no grass, bush, paper,
rags, stone, sand, etc. adhering or
trapped on the underbody. Clear off
any such matter from the under-
body. If the vehicle is used with
these materials trapped or adhering
to the underbody, a breakdown or
fire could occur.
In a rollover crash, an unbelted per-
son is significantly more likely to
die than a person wearing a seat
belt. Therefore, the driver and all
passengers should fasten their seat
belts whenever the vehicle is mov-
ing.
When driving offroad or in rugged
terrain, do not drive at excessive
speeds, jump, make sharp turns,
strike objects, etc. This may cause
loss of control or vehicle rollover
causing death or serious injury. You
are also risking expensive damage
to your vehicle’s suspension and
chassis.
NOTICE
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the river bed for
firmness. Drive slowly and avoid
deep water.
 Take all necessary safety measures
to ensure that water damage to the
engine or other components does
not occur.
Water entering the engine air intake
will cause severe engine damage.
Water can wash the grease from
wheel bearings, causing rusting and
premature failure, and may also en-
ter the differentials, transmission
and transfer case, reducing the gear
oil’s lubricating qualities.
 Sand and mud that has accumulated
in brake drums and around brake
discs may affect braking efficiency
and may damage brake system com-
ponents.
