CHECKING AND REPLACING
THE BLADE TYPE FUSES
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.
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. Install only a fuse with the amperage rating designated on
the fuse box lid.

216If you do not have a spare fuse, in an emergency you can pull
out the “CIG”, “RADIO NO. 1”, “DOME” or “SEAT HTR” 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 another
object, in place of a fuse. This may cause extensive
damage and possibly a fire.
CHECKING THE CARTRIDGE
TYPE FUSES
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
melted, they must be replaced.

217 If there is an overload in the circuits from the battery, the fuses
are designed to melt 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.
REPLACING THE WINDSHIELD
WIPER BLADES
When the wipers no longer clean adequately, the wiper
blades may be worn or cracked, and require replacement.
Before replacement
Make sure whether the wiper blades are at the rest
position or at the retracted position.
If at the rest position---
Swing the wiper arm away from the windshield until it stands
up.
