CHECKING AND REPLACING THE

details, see Removing the engine compartment coversº
on page 526.)

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.

ELECTRICAL COMPONENTS
597 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
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 Removing the engine compartment coversº
on page 526.)

Good
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.
NOTICE
Before replacing the fuses, have the cause of electrical
overload determined and repaired by your Lexus dealer.
