CAUTION!
The SRS airbag system is designed
only as a supplement to the primary
protection of the driver side seat belt
systems. The driver is particularly
susceptible to death or serious inju-
ry if he/she does not wear his/her
seat belt; when sudden braking or a
collision occurs, he/she may be
thrown forward into the deploying
SRS aribag. To obtain a maximum
protection in an accident, the driver
and all passengers in the vehicle
should always wear their seat belts when driving because serious inju-
ries can result to unrestrained occu-
pants. For instructions and precau-
tions concerning the seat belt sys-
tem, see Seat beltsº in this chapter.
CAUTION!
Do not put objects on the steering
wheel pad. They might restrict
inflation or cause serious injury as
they are projected rearward by the force of a deploying airbag.
Do not modify or remove any wir-
ing. Do not modify, remove or open any components such as the steer-
ing wheel column cover, airbag
sensor assembly. Doing any of
these may cause sudden SRS air-
bag inflation or disable the system,
which could result in death or seri-
ous injury.
Failure to follow these instructions can result in death or serious inju- ries.
NOTICE
Do not perform any of the following changes without consulting your
Toyota dealer. Such changes caninterfere with proper operation of the SRS airbag system in somecases.
Installation of electronic itemssuch as a mobile two-way radio,
cassette tape player or compactdisc player
Modification of the suspension
system
Modification of the front endstructure
Attachment of a grille guard (bullbar, kangaroo bar, etc.), snow-
plow winches or any other equip-
ment to the front end
Repairs made on or near the front end structure, console, steeringcolumn or steering wheel

Types of tires
This vehicle is one of the class of ve-
hicles which have higher ground
clearance and narrower tread in rela-
tion to the height of their center of
gravity to make them capable of per- forming in a wide variety of off-road applications. Specific design charac-
teristics give it a hi
gher center or grav-
ity than ordinary cars. An advantage ofthe higher ground clearance is a better view of the road allowing you to antici-
pate problems. It is not designed for
cornering at the same speeds as con-
ventional two-wheel drive vehicles
any more than low-slung sports cars
are designed to perform satisfactorily under off-road conditions.
CAUTION!
Always obeserve the following pre-
cautions to minimize the risk of seri-
ous personal injury or damage to
your vehicle: Avoid sharp turns or abrupt maneu-
vers, if at all possible. As with other
vehicles of this type, failure to oper-
ate this vehicle correctly may result
in loss of control or vehicle rol-
lover.
Avoid l oading any items on the roof
that will make the center of gravity
even higher.
Always slow down in gusty cross-
winds. Because of its high center of
gravity, your vehicle is more sensi-
tive to side winds than an ordinary
passenger car. Slowing down will
allow you to have much better con- trol.
Do not drive horizontally across
steep slopes. Driving straight up or
straight down is preferred. Your ve-
hicle (or any similar off-road ve-
hicle) can tip over sideways much
more easily than forward or back- ward.

CAUTION!
When driving off-road or in rugged
terrain, do not drive at excessive
speeds, jump the vehicle, or strike
objects, etc. This may cause loss of
control or vehicle rollover. You are
also risking expensive damage to
your vehicle's suspension and chassis. Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
break-in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of your vehicle:
Do not drive over 88 km/h (55 mph).
Run the engine at moderate speed be- tween 2000 and 4000 rpm.
Avoid full-throttle starts.
Try to avoid hard stops during the first
300 km (200 miles).
Do not drive slowly with the manual
transmission in a high gear.
Do not drive for a long time at any
single speed, either fast or slow.
Do not tow a trailer during the first 800
km (500 miles)
Four-wheel drive models with free-
wheeling hubs onlyÐ For the first 500 km (300 miles):
We recommend that you use high range,
two-wheel drive, with both free-wheeling
hubs engaged. For information on the four-wheel drive system and the front hubs, see Four-wheel drive system in Chapter 1-6. FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mixups, your
Toyota has a new smaller fuel tank opening.
The special nozzle on pumps with unleaded
fuel will fit it, but the larger standard nozzle
on pumps with leaded gas will not.
Do not use leaded gasoline. Use of
leaded gasoline will cause the
three-way catalytic converter to lose its effectiveness and theemission control system to function improperly. Also, thiscan increase maintenance costs.
NOTICE
OCTANE NUMBER
Select Research Octane Number 91 (Oc-
tane Rating 87) or higer.
Use of unleaded fuel with an octane num- ber or rating lower than stated above will
cause persistant heavy knocking. If se-
vere, this will lead to engine damage.Fuel

engine block as shown.
CAUTION!
Do not modify the suspension/
chassis with lift kits, spacers,
springs, etc. It can cause danger-
ous handling characteristics, re-
sulting in loss of control. Determine what kind of tires your ve-
hicle is originally equipped with 1.
Summer tires
Summer tires are high-speed capability
tires best suited to highway driving underdry conditions. Since summer tires do not have the same
traction performance as snow tires, sum-
mer tires are inadequate for driving on
snow-covered or icy roads. For driving on
snow-covered or icy roads, we recom-
mend using snow tires. If installing snow tires, be sure to replace all four tires. 2. All season tires
All season tires are designed to provide
better traction in snow and to be adequate
for driving in most winter conditions, as
well as for use all year round.
All season tires, however, do not have ad-
equate traction performance compared
with snow tires in heavy or loose snow.
Also, all season tires fall short in accelera-
tion and handling performance compared with summer tires in highway driving.

6. After making sure that no one is in the vehicle, raise it high enough so
that the spare tire can be installed.
Remember you will need more ground
clearance when putting in the spare tire than when removing the flat tire.
Normal cab modelsÐTo raise the vehicle,
insert the jack handle into the jack (it is a
loose fit) and turn it clockwise. As the jack
touches the vehicle and begins to lift,
double-check that it is properly posi- tioned.

mech-
anism
Check the lock release button of the se-
lector lever for proper and smooth opera-
tion. On a safe incline, check that your ve-
hicle is held securely with the selector lever in ºPº position and all brakes re- leased.
IN THE ENGINE COMPARTMENT Items listed below should be checked
from time to time , e.g. each time when
refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See Chapter 7-3 for additional infor-
mation.
Engine coolant level Make sure the coolant level is between
the FULLº and LOWº lines on the see-
through reservoir when the engine is cold.
See Chapter 7-2 for additional informa-tion.
Battery electrolyte level Make sure the electrolyte level of all bat-
tery cells is between upper and lower level
lines on the case. Add only distilled water
when replenishing. See Chapter 7-3 for
additional information. Brake fluid level
Make sure the brake fluid level is correct. See Chapter 7-2 for additional informa- tion.
Engine oil level
Check the l
evel on the dipstick with the en-
gine turned off and the vehicle parked on
a level spot. See Chapter 7-2 for addition-
al information. Power steering fluid level Check the level on the dipstick. The level
should be in the HOTº or COLDº range
depending on the fluid temperature. SeeChapter 7-2 for additional information. Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have the cause located and corrected immedi-
ately. (See engine exhaust cautions in
Part 2.) Be on the alert for changes in perfor-
mance, sounds, and visual tip-offs
that in-
dicate service is needed. Some important
clues are as follows: Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)
Flat-looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when drivingstraight on a level road
Strange noises related to suspensionmovement
Loss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking
Engine coolant temperature continual-
ly higher than normal
