Checking The Cartridge Type Fuses - Lexus RX300 Manual

ELECTRICAL COMPONENTS
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
"RAD NO.1", "RAD NO.2" or "PWR OUTLET" 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.
