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 locations" on page 430 in Sec-
tion 7−1 for locations of the fuses.
Turn the engine switch and inoperative
component off. Pull the 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
page 468 in Section 8 for the functions
controlled by each circuit. Type A fuses can be pulled out by using
the 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 PWR
OUTLET" or HEATER NO.2" fuse, which
may be dispensable for normal driving,
and use it if its amperage rating is the
same.
If you cannot use one of the same amper-
age, use one that is lower, but as close
to the rating as possible. 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 ve-
hicle for emergencies.
Checking and replacing fuses

453
If 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.
CAUTION
Never use a fuse with a higher am-
perage rating, or any other object, in
place of a fuse. This may cause ex-
tensive damage and possibly a fire.CY73025
If any washer does not work, the wash-
er tank may be empty. Check the wash-
er fluid level on the level gauge. If the
washer fluid level is below LOW" or
only slightly above the LOW" level,
add washer fluid.
For vehicles sold in Canada
If any washer does not work or low
windshield washer fluid level warning
light comes on, the washer tank may be
empty. Add washer fluid.You may use plain water as washer fluid.
However, in cold areas where tempera-
tures range below the 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 dam-
age your vehicle’s paint.

The following illustrations show how to
gain access to the bulbs. When replacing
a bulb, make sure the engine switch and
light switch are off. Use bulbs with the
wattage ratings given in the table.
The stop/tail and rear side marker lights
consist of a number of LEDs. If any of
the LEDs burn out, take your vehicle to
your Toyota dealer to have the light re-
placed.
CAUTION
To prevent burning yourself, do not
replace the light bulbs while they
are hot.
Halogen bulbs have pressurized gas
inside and require special handling.
They can burst or shatter if
scratched or dropped. Hold a bulb
only by its plastic or metal case.
Do not touch the glass part of a
bulb with bare hands.
NOTICE
Only use a bulb of the listed type.
The inside of the lens of exterior lights
such as headlights may temporarily fog up
when the lens becomes wet in the rain or
in a car wash. This is not a problem
because the fogging is caused by the
temperature difference between the outside
and inside of the lens, just like the
windshield fogs up in the rain. However, if
there is a large drop of water on the
inside of the lens, or if there is water
pooled inside the light, contact your
Toyota dealer.
