If you perform maintenance by yourself,
be sure to follow the correct procedure
given in this part.
You should be aware that improper or in-
complete servicing may result in operating
problems.
Performing do-it-yourself maintenance dur-
ing the warranty period may affect your
warranty coverage. Read the separate
Toyota Warranty statement for details and
suggestions.
This part gives instructions only for those
items that are relatively easy for an owner
to perform. As explained in Part 6, there
are still a number of items that must be
done by a qualified technician with special
tools.
For information on tools and parts for do-
it-yourself maintenance, see ºParts and
toolsº.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few precautions that
you should be especially careful to ob-
serve:
Do-it-yourself service
precautions

'98 Tacoma (U)
202
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.

'98 Tacoma (U)207
NOTICE
Avoid overfilling, or the enginecould be damaged.
Check the oil level on the dipstickonce again after adding the oil.
Engine oil selection
Use API grade SH, ºEnergy-Conserving IIº
or SJ, Energy- Conservingº multigrade en-
gine oil or ILSAC multigrade engine oil.
Recommended viscosity (SAE):
SAE 5W- 30 is the best choice for your
vehicle, for good fuel economy, and
good starting in cold weather.
If you use SAE 10W- 30 engine oil in
extremely low temperatures, the engine
may become difficult to start, so SAE
5W- 30 engine oil is recommended.
API service symbol
ILSAC certification mark Oil identification marks
Either or both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any-
where on the outside of the container.
The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SJ. The center
portion of the label shows the SAE viscos-
ity grade such as SAE 5W- 30. ºEnergy-
Conservingº shown in the lower portion,
indicates that the oil has fuel-saving capa-
bilities.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is displayed on the front of
the container.

AND CAMPER
INFORMATION

Uniform tire quality grading
Camper information
If you believe that your vehicle
has a defect which could cause a
crash or could cause injury or
death, you should immediately in-
form the National Highway Traffic
Safety Administration (NHTSA) in
addition to notifying Toyota Motor
Sales, U.S.A., Inc. (Toll- free:
1- 800- 331- 4331).
If NHTSA receives similar com-
plaints, it may open an investiga-
tion, and if it finds that a safety
defect exists in a group of ve-
hicles, it may order a recall and
remedy campaign. However,
NHTSA cannot become involved
in individual problems between
you, your dealer, or Toyota Motor
Sales, U.S.A., Inc.
To contact NHTSA, you may ei-
ther call the Auto Safety Hotline
toll- free at 1- 800- 424- 9393 (or
366- 0123 in Washington.D.C.
area) or write to: NHTSA. U.S.De-
partment of Transportation. Wa-
shington.D.C. 20590. You can also
obtain other information about mo-
tor vehicle safety from the Hotline.
This information has been prepared in ac-
cordance with regulations issued by the
National Highway Traffic Safety Adminis-
tration of the U.S. Department of Trans-
portation. It provides the purchasers and/
or prospective purchasers of Toyota
vehicles with information on uniform tire
quality grading.
Your Toyota dealer will help answer any
questions you may have as you read this
information.
DOT quality gradesÐAll passenger ve-
hicle tires must conform to Federal
Safety Requirements in addition to
these grades. These quality grades are
molded on the sidewall.
TreadwearÐ
The treadwear grade is a
comparative rating based on the wear rate
of the tire when tested under controlled
conditions on a specified government test
course. For example, a tire graded 150
would wear one and a half (1- 1/2) times
as well on the government course as a
tire graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may de-
part significantly from the norm due to
variations in driving habits, service prac-
tices and differences in road characteris-
tics and climate.

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.
