1. Turn the ignition switch off and remove the auxiliary box.
Determine which fuse may be causing the problem. The auxiliary 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.
64L014
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 suspe\
cted 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 ºRAD
NO.1º, ºRAD NO.2º or ºPWR OUTLETº 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 clo\
se
as possible to, the amperage. If the amperage is lower than that specifie\
d, 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 elect\
rical
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.

If the headlights or other electrical components do not work and the blade\

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.
ADDING WASHER FLUID
64E017±1
If the washer tank becomes nearly empty, add washer fluid.
You may use plain water as washer fluid. However, in cold areas where
temperatures range below the freezing point, use washer fluid containing
antifreeze. This product is available at your Lexus dealer and most auto parts
stores. Follow the manufacturer's directions for how much to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute because it may
damage your vehicle's paint.
