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 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:
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 flam-
mable.
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
!
Be sure that the ignition is off if you
work near the electric cooling fans
or radiator grille. With the ignition
on, the electric cooling fans will au-
tomatically start to run if the engine
coolant temperature is high and/or
the air conditioning is on.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to fly-
ing or falling material, fluid spray,
etc.
Used engine oil contains potential-
ly 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 the
reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and filter
in household trash, in sewers or
onto the ground. Call your dealer
or a service station for information
concerning recycling or disposal.

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
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 the
norm due to variations in driving habits,
service practices and differences in road
characteristics and climate. Traction A, B, CÐThe 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 to degener-
ate and reduce tire life, and excessive
temperature can lead to sudden tire fail-
ure. The grade C corresponds to a level of
performance which all passenger car tires
must meet under the Federal Motor Ve-
hicle Safety Standard No. 109. Grades B
and A represent higher levels of perfor-
mance 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 tire
failure.
