problems.
Performing doityourself maintenance
during the warranty period may affect your
warranty coverage. Read the separate
Toyota Warranty statement for details and
suggestions.
This section gives instructions only for
those items that are relatively easy for an
owner to perform. As explained in Section
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
ityourself maintenance, see “Parts and
tools”.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental

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 71 for
locations of the fuses.
Turn the ignition switch and inoperative
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
Section 8 of this manual for the functions
controlled by each circuit. Type A fuses can be pulled out by the
pullout tool. The location of the pullout
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 “A.C”
fuse, which may be dispensable for nor-
mal 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
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 ve-
hicle for emergencies.
