3. “4LO” (low speed position, four
wheel drive): With the “2WD/4HI”
switch pressed in, push the “4LO”
switch
The “4LO” 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, off−road driving,
and hard pulling in s and, mud or deep
snow.
In this mode, the vehicle stability con-
trol system is off. (See “Vehicle stabil-
ity control system” in this Section.)
See “(c) Shifting procedure” 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 “2WD” AND “4HI”
To shift from “2WD” to “4HI”,
reduce
the vehicle speed to less than 100 km/h
(62 mph) and push in the “2WD/4HI”
switch.
If the “4HI” indicator light flashes when
you push in the “2WD/4HI” switch, this
reminds you that the transfer mode is not
securely in “4HI” mode. Drive straight
ahead while accelerating or decelerating.
If the “4HI” indicator light flashes and the
buzzer sounds when you push in the
“2WD/4HI” switch, this reminds you that
the transfer mode is not in “4HI” mode.
Reduce the vehicle speed to less than
100 km/h (62 mph). Push the switch to
turn it off, then once again to turn it back
on.
CAUTION
Never push the “2WD/4HI” switch if
the wheels are slipping. Stop the slip-
ping or spinning before shifting.

The side step is for easier stepup
loading.
CAUTION
For models equipped with a StepSide
bed:
Do not allow more than one person
to get on the side step. Do not
exceed the maximum weight limit of
136 kg (300 lb.) on the side step.
Never drive the vehicle with anyone
on the side steps.
Do not stand on the side steps
while the vehicle is moving.
Some Toyotas are equipped with a lim-
ited−slip differential. If one of the rear
wheels begins to spin, the limited −slip 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.

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.
Always perform a maintenance in-
spection after each day of offroad
driving that has taken you through
rough terrain, sand, mud, or water.
For scheduled maintenance in-
formation, refer to the “Scheduled
Maintenance Guide” or “Owner’s
Manual Supplement”.Make sure your coolant is properly pro-
tected against freezing.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non −silicate, non −amine, non− nitrite,
and non− borate coolant with long −life
hybrid organic acid technology. (Coolant
with long −life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
See “Checking the engine coolant level” in
Section 7 −2 for details of coolant type
selection.
For the U.S.A.—“Toyota Super Long Life
Coolant” is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about −35 C
( − 31 F).
For Canada—“Toyota Super Long Life
Coolant” is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about −42 C
( − 44 F).
NOTICE
Do not use plain water alone.
