CHECKING THE CIRCUIT
BREAKERS
Driver’s side

Circuit breakers
In the event the defogger, air conditioning, power
windows, power door locks, or moon roof does not
operate, check its circuit breaker (C
.B).
To reset the circuit breaker, first turn the ignition switch off and
carefully insert a thin object, such as a toothpick, needle or
safety pin, into the hole in the circuit breaker and push until you
hear a click. The component should now operate. This may be
done without removing the circuit breaker.
If the circuit breaker immediately goes off again or the
component does not operate, turn off the component switch
and have the electrical system checked by your Lexus dealer
as soon as possible.
CHECKING THE CARTRIDGE TYPE
FUSES
GoodMelted
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.
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.
