If you perform maintenance by your-
self, be sure to follow the correct pro- cedure given in this part.
You should be aware that improper or in- complete servicing may result in operat-
ing problems.
Performing do-it-yourself maintenance
during the warranty period may affect
your warranty coverage. Read the sepa-
rate 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 Parts andtoolsº.
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

195
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, radia-
tor, exhaust manifold, power
steering fluid reservoir and spark
plug boots, etc.Ðwill be hot. So
be careful 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 flamable.
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.
Always use automotive jack
stands or other solid supports. CAUTION
!
Use eye protection whenever you
work on or under you vehicle
where you may be exposed to fly-
ing or falling material, fluid spray, etc.
Used engine oil contains poten-
tially harmful contaminants which
may cause skin disorders such as
inflammation or skin cancer, so
care should be taken to avoid pro-
longed and repeated contact with
it. To remove used engine oil from
your skin, wash thoroughly with
soap and water.
Do not leave used oil within thereach 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 deal- er or a service station for informa-
tion concerning recycling or dis- posal. Remember that battery and igni-
tion cable carry high currents or
voltages. Be careful of accidental-
ly causing a short circuit.
Add only demineralized or dis- tilled water to fill the radiator. And
if you spill some of the coolant, be sure to wash it off with water to
prevent it from damaging theparts or paint.
Do not allow dirt or anything else
to 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 will
cause engine damage, loss of per-
formance or radio noise.
Do not overfill automatic trans-
mission fluid, or the transmission
could be damaged.
NOTICE

200ENGINE OIL SELECTION Use API SH, Energy-Conserving IIº mul- tigrade engine oil or ILSAC multigrade en-
gine 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 en-
gine may become difficult to start, so
SAE 5W-30 engine oil is recom-mended.
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 SH. The cen-
ter portion of the label shows the SAE vis-
cosity grade such as SAE 5W-30.
Energy-Conserving IIº shown in the low-
er portion, indicates that the oil has fuel-
saving capabilities. Oils marked Ener-
gy-Conserving IIº will have higher
fuel-saving capabilities than oil marked Energy-Conservingº.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee)Certification Mark is displayed on the front
of the container.

226This
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
vehicle tires must conform to Federal
Safety Requirements in addition to these grades. These quality grades are
molded on the sidewall.
Treadwear ÐThe treadwear grade is a
comparative rating based on the wear
rate of the tire when tested under con-
trolled conditions on a specified govern-
ment 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 conditions of their use, however,
and may depart significantly from thenorm due to variations in driving habits,
service practices and differences in road characteristics and climate. Traction A, B, C
ÐThe traction grades,
from highest to lowest, are A, B, and C,
and they represent the tire's ability to stop
on wet pavement as measured under
controlled conditions on specified govern-
ment test surfaces of asphalt and con-
crete. A tire marked C may have poor trac-
tion performance.
Warning: The traction grade assigned to this tire is based on braking (straight
ahead) traction tests and does not include
cornering (turning) traction.
Temperature A, B, C ÐThe temperature
grades are A (the highest), B, and C, rep-
resenting the tire's resistance to the gen-
eration of heat and its ability to dissipate heat when tested under controlled condi- tions on a specific indoor laboratory test
wheel. Sustained high temperature can cause the material of the tire life, and ex- cessive temperature can lead to sudden
tire failure. The grade C corresponds to a level of performance which all passenger
car tires must meet under the Federal Mo-
tor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law. Warning: The temperature grades for this tire
are established for a tire that is proper-
ly inflated and not overloaded. Excessive speed, underinflation, or excessive load- ing, wither separately or in combination, can cause heat buildup and possible tirefailure.
