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” in Section 7 −1 for
locations of the fuses.
Turn the ignition 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
Section 8 for the functions controlled by
each circuit.
Type D—When any of the fuses are
blown, contact your Toyota dealer.
Type A fuses can be pulled out by 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 “DOME”
or “A/C” 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
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.
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.
If any washer does not work or the 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.

on the bulb base and the mounting body.
Aiming is not necessary after replacing
the bulb. When aiming adjustment is nec-
essary, contact your Toyota dealer. If either the left or right front fog lights
burns out, contact your Toyota dealer.
NOTICE
Do not try to replace the front fog
light bulbs by yourself. You may dam-
age the vehicle.
