Odometer and two trip meters
Service reminder indicators and
warning buzzers
Fuel gauge
With tachometer
Without tachometer
The gauge works when the ignition
switch is on and indicates the approxi-
mate quantity of fuel remaining in the
tank.
Nearly fullÐNeedle at ºFº
Nearly emptyÐNeedle at ºEº
It is a good idea to keep the tank over
1/4 full.
This fuel gauge has a non-return type
needle which remains at the last indicated
position when the ignition switch is turned
off.
If the fuel level approaches ºEº or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the fuel gauge
needle may fluctuate or the low fuel level
warning light may come on earlier than
usual.
If the fuel tank is completely empty, the
malfunction indicator lamp comes on. Fill
the fuel tank immediately.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.

Types of tires
This vehicle is one of the class of ve-
hicles which have higher ground clear-
ance and narrower tread in relation to
the height of their center of gravity to
make them capable of performing in a
wide variety of off-road applications.
Specific design characteristics give it a
higher center of gravity than ordinary
cars. An advantage of the higher
ground clearance is a better view of the
road allowing you to anticipate prob-
lems. It is not designed for cornering
at the same speeds as conventional
two-wheel drive vehicles any more than
low-slung sports cars are designed to
perform satisfactorily under off-road
conditions.
CAUTION
Always observe the following precau-
tions to minimize the risk of serious
personal injury or damage to your ve-
hicle:
Avoid sharp turns or abrupt maneu-
vers, if at all possible. As with oth-
er vehicles of this type, failure to
operate this vehicle correctly may
result in loss of control or vehicle
rollover.
Avoid loading 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.
Off-road vehicle pr ecautions
(four-wheel drive models only)

'98 Tacoma (U)
138
When driving off-road or in r ugged
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 chas-
sis.
Break-in period
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 ºFour-wheel drive systemº in
Chapter 1- 6. Fuel
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 open-
ing. The special nozzle on pumps with
unleaded fuel will fit it, but the larger
standard nozzle on pumps with leaded gas
will not.
At a minimum, the gasoline you use
should meet specifications of ASTM
D4814 in the U.S.A. and CGSB 3.5- M93
in Canada.
NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three-way catalytic converter to lose its ef-
fectiveness and the emission control
system to function improperly. Also,this can increase maintenance costs.

Automatic transmission ºPark'' mecha-
nism
Check the lock release button of the se-
lector lever (floor shift type) for proper
and smooth operation. On a safe incline,
check that your vehicle is held securely
with the selector lever in ºP'' position and
all brakes released.
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 in-
formation.
Engine coolant level
Make sure the coolant level is between
the ºFULL'' and ºLOW'' lines on the see-
through reservoir when the engine is cold.
See Chapter 7- 2 for additional information.
Battery electrolyte level
Make sure the electrolyte level of all bat-
tery cells is between upper and lower lev-
el 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 information.
Engine oil level
Check the level on the dipstick with the
engine turned off and the vehicle parked
on a level spot. See Chapter 7- 2 for addi-
tional information.
Power steering fluid level
Check the level on the dipstick. The level
should be in the ºHOT'' or ºCOLD'' range
depending on the fluid temperature. See
Chapter 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
indicate service is needed. Some impor-
tant 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 monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)
Flat-looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when driving
straight on a level road
Strange noises related to suspension
movement
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 continually
higher than normal
Does your vehicle need
repairing?

CAUTION
When the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
Right after driving, the engine
compartmentÐthe engine, radiator,
exhaust manifold, power steering
fluid reservoir and spark plug
boots, etc.Ðwill be hot. So be care-
ful not to touch them. Oil, fluids
and spark plugs may also be hot.
If the engine is hot, do not remove
the radiator cap or loosen the drain
plugs to prevent burning yourself.
Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flammable.
Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
Do not leave used oil within the
reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.NOTICE
Remember that battery and ignition
cables carry high currents or volt-ages. Be careful of accidentallycausing a short circuit.
Add only demineralized or distilled water to fill the radiator. And if youspill some of the coolant, be sure
to wash it off with water to preventit from damaging the parts or paint.
Do not allow dirt or anything elseto fall through the spark plug holes.
Do not pry the outer electrode of a
spark plug against the center elec-trode.
Use only spark plugs of the speci-fied type. Using other types willcause engine damage, loss of per-
formance or radio noise.
Do not overfill automatic transmis-sion fluid, or the transmissioncould be damaged.
Do not drive with the air cleaner
filter removed, or excessive enginewear could result. Also backfiringcould cause a fire in the engine
compartment.

Spark ignition system of your
To y o t a
The spark ignition system in your Toyota meets all re-
quirements of the Canadian Interference- Causing Equip-
ment Standard.
Installation of a mobiletwo- way radio system
As the installation of a mobile two- way radio system in
your vehicle could affect electronic systems such as
multiport fuel injection system/sequential multiport fuel
injection system, cruise control system, anti- lock brake
system and SRS airbag system, be sure to check with
your Toyota dealer for precautionary measures or special
instructions regarding installation.
Scrapping of your Toyota
The SRS airbag devices in your Toyota contains explo-
sive chemicals. If the vehicle is scrapped with the air-
bags left as they are, it may cause an accident such as
a fire. Be sure to have the SRS airbag system removed
and disposed of by a qualified service shop or by your
Toyota dealer before you dispose of your vehicle.
On- pavement and off- road driving tips
(four-wheel drive models only)
This vehicle will handle and maneuver differently from an
ordinary passenger car because it is also designed for
off- road use. As with other vehicles of this type, failure
to operate this vehicle correctly may result in loss of
control or an accident. Be sure to read ºOff- road vehicle
precautionsº in Part 2 and ºOff- road driving precautionsº
in Part 3.
