CHECKING AND REPLACING THE
BLADE TYPE FUSES

Engine compartment 1
Spare fuses 2
Pullout 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 pullout tool and check it.
If it has blown, push a new fuse into the clips.

Good
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
”RADIO NO.1” ”MIRHTR” or ”OBD” 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

Good 2
Melted
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 wireeven for a
temporary fix. This may cause extensive damage and possibly
a fire.
