CHECKING AND REPLACING THEBLADE TYPE FUSES
The engine compartment fuse box is located under the left
side engine compartment cover. Before checking the
engine compartment fuses, remove the cover. (For
details, see ªRemoving the engine compartment coversº
on page 538.)

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.

Blown
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 ªCIGº, ªRADIO NO.1º or ªSEAT HEATERº 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 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 clips.

ELECTRICAL COMPONENTS
616It 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
The engine compartment fuse box is located under the left
side engine compartment cover. Before checking the
engine compartment fuses, remove the cover. (For
details, see ªRemoving the engine compartment coversº
on page 538.)

Blown
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.
CAUTION
Always use a genuine Lexus fuse or equivalent for
replacement. Never install an ordinary wire Ð even for
a temporary fix. This may cause extensive damage and
possibly a fire.
NOTICE
Before replacing the fuses, have the cause of electrical overload determined and repaired by your Lexus dealer.
