2002 Lexus ES300 Headlight fuse

SWITCHES
31
HEADLIGHT DIMMER AND TURNSIGNAL SWITCH
For high beam, push the lever forward. Pull it back for low
beam. For the headlight flasher, pull it further back.
A blue light in the instrument cluster indicates high beam or
headlight flasher is on.
The headlight flasher works even when the headlight switch is
off.
For signaling turns, move the lever up or down in the
conventional manner.
The ignition key must be in the “ON” position.
The turn signal is selfcancelling after a turn, but after a lane
change, you may have to cancel it by hand. You can also signal
a lane change by moving the turn signal lever partway and
holding it there.
If the green light in the instrument cluster flashes faster than
normal, it indicates that the front or rear turn signal bulb has
burned out. If this indicator light does not come on, the fuse
or the indicator light itself has probably failed.

CHECKING THE CARTRIDGE TYPEFUSES
Engine compartment
Driver’s side instrument panel 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.
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.
NOTICE
Before replacing the fuses, have the cause of electrical
overload determined and repaired by your Lexus dealer.
