CHECKING AND REPLACING THE
BLADE TYPE FUSES
Driver's side instrument panel
Engine compartment
Spare fuses
Pull±out tool
1. Turn the ignition switch off and open the fuse box
lid.Determine which fuse may be causing the problem. The lid
of the fuse box shows the name of the circuit for each fuse.
2. Make sure the inoperative component is turned off.
Pull the suspected fuse straight out with the pull±out
tool and check it. If it has blown, push a new fuse into
the clips.

GoodBlown
a. Look carefully at the fuse. If the thin wire is broken, the
fuse has blown. If you are not sure or if it is too dark to see,
try replacing the suspected fuse with one of the same value
that you know is good.
b. Only install a fuse with the amperage rating designated
on the fuse box lid.
If you do not have a spare fuse, in an emergency you can pull
out the ªRADIO NO.1º, ªMIR±HTRº or ªDOME RRº 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 amperage, use one lower
than, but as close as possible to, the amperage. 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 clips.It is a good Idea to purchase a set of spare fuses and keep
them in your vehicle for emergencies.
If the new fuse immediately blows out, there is a problem
with the electrical system. Have your Lexus dealer correct
it as soon as possible.
CAUTION!
Never use a fuse with a higher amperage rating, or
any other object, in place of a fuse. This may cause
extensive damage and possibly a fire.

CHECKING THE CARTRIDGE
TYPE FUSES

GoodMelted
If the headlights or other electrical components do not
work and the blade type fuses are O.K., check the
cartridge type fuses. If any of the cartridge type fuses
are blown, they must be replaced.
If there is an overload in the circuits from the battery, the
fuses are designed to blow before the entire wiring harness
is damaged.
NOTICE
Before replacing the fuses, have the cause of
electrical overload determined and repaired by your
Lexus dealer.
CAUTION!
Always use a genuine Lexus fuse or equivalent for
replacement. Never install an ordinary wire±even for
a temporary fix. This may cause extensive damage
and possibly a fire.
