If the headlights or other electrical
components do not work, check the
fuses. If any of the fuses are blown,
they must be replaced.
See Fuse locationsº in Chapter 7-1 for
locations of the fuses.
Turn the ignition switch and inopera-
tive component off. Pull a suspected
fuse straight out and check it. Determine which fuse may be causing the
problem. The lid of the fuse box shows the name of the circuit for each fuse. See Part8 of this manual for the functions con-
trolled by each circuit. Type A fuses can be pulled out by usingthe pull-out tool. The location of the pull- out tool is shown in the illustration.
If you are not sure whether the fuse has
blown, try replacing the suspected fuse with one that you know is good.
If the fuse has blown, push a new fuse
into the clip.
Only install a fuse with the amperage rat-
ing designated on the fuse box lid.
If you do not have a spare fuse, in an emergency you can pull out the DOMEº or A/Cº fuse, which may be dispensable
for normal driving, and use it if its amper- age rating is the same.
If you cannot use one of the same amper-
age, use one that is lower, but as close as
possible to the rating. If the amperage is
lower than that specified, the fuse might
blow out again but this does not indicate
anything
wrong. Be sure to get the correct
fuse as soon as possible and return the
substitute to its original clip.
It is a good idea to purchase a set of spare
fuses and keep them in your vehicle for emergencies.
Checking and replacing fuses

212If the new fuse immediately blows out, there is a problem with the electrical sys-
tem.
Have your Toyota dealer correct it as
soon as possible.
Never use a fuse with a higher
amperage rating, or any other
object, in place of a fuse. This maycause extensive damage and
possibly a fire. CAUTION
!
If any washer does not work, the wash-
er tank may be empty. Add washer fluid.
You may use plain water as washer fluid.
However, in cold areas where tempera-
tures range below freezing point, use
washer fluid containing antifreeze. This
product is available at your Toyota dealer
and most auto parts stores. Follow the
manufacturer 's directions for how much
to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute because it may
damage your vehicle's paint.
The following illustrations show how to
gain access to the bulbs. When replacing
a bulb, make sure the ignition switch and
light switch are off. Use bulbs with the wattage ratings given in the table.
NOTICE
Only use a bulb or unit of the listed type.

If the connector is tight, wiggle it.2. Release the bulb retaining spring and remove the bulb. Install a new
bulb and the bulb retaining spring.
To install a bulb, align the tabs of the bulb with the cutouts of the mounting hole.

U.S. owners
Uniform tire quality grading
If you believe that your vehicle has
a defect which could cause a crash
or could cause injury or death, you
should immediately inform the
National Highway Traffic Safety
Administration (NHTSA) in addi-
tion to notifying Toyota Motor Sales, U.S.A., Inc.
(Toll-free: 1- 800-331-4331).If NHTSA receives similar com- plaints, it may open a investiga-
tion, and if it finds that a safety
defect
exists in a group of vehicles,
it may order a recall and remedy
campaign. However, NHTSA can-
not become involved in individual
problems between you, your deal-
er, or Toyota Motor Sales, U.S.A.,Inc. To contact NHTSA, you may eithercall 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. Department
of Transportation. Washington
D.C. 20590. You can also obtain
other information about motor ve- hicle safety from the Hotline.

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.
