SWITCHES
50
G12005
For signaling turns, move the lever up or down in the
conventional manner.
The engine switch must be selected in “IG−ON” mode.
The turn signal is self −cancelling 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.
FOG LIGHT SWITCH
G12006
To turn on the fog lights, twist the band of the headlight
lever to the fog light mark. They will come on only when
the headlights are on low beam.
When the fog lights are on, the indicator lights up in the
instrument cluster.

Turn the bolt B in either direction using a Phillips−head
screwdriver.
If you do not know or cannot find the original position, or if you
feel that there is a large deviation, take the vehicle to your
Lexus dealer to adjust the headlight aim.
REPLACING LIGHT BULBS
The illustrations on the following pages show the locations of
light bulbs. If it is necessary to replace a bulb, take your vehicle
to your Lexus dealer as soon as possible. Use bulbs with the
bulb numbers and wattage ratings given in the table.
The tail lights, stop lights, high mounted stoplight and rear side
marker light consist of a number of LEDs. If any of the LEDs
burn out, take your vehicle to your Lexus dealer to have the
light replaced.
If two or more LEDs in a stoplight burn out, your vehicle may
not conform to local laws (SAE).
CAUTION
 To prevent burning yourself, do not replace the light
bulbs while they are hot.
 Halogen bulbs have pressurized gas inside and
require special handling. They can burst or shatter if
scratched or dropped. Hold a bulb only by its plastic
or metal case. Do not touch the glass part of a bulb
with bare hands.
 Do not touch the (Highintensity discharge
headlight’s) high voltage socket when the headlights
are turned on. An extremely high voltage of 20,000 V
will be discharged and could result in serious injury
or death by electric shock.

ELECTRICAL COMPONENTS
595
Do not attempt to take apart or repair the low beam
headlight bulbs, connectors, power supply circuits,
or related components. Doing so could result in elec-
tric shock and serious injury or death. Call your Lex-
us dealer for headlights repair or servicing, including
replacement of bulbs and bulb disposal.
NOTICE
Only use a bulb of the listed type.
The inside of the lens of exterior lights such as headlights may
temporarily fog up when the lens becomes wet in the rain or in
a car wash. This is not a pr oblem because the fogging is
caused by the temperature dif ference between the outside and
inside of the lens, just like the windshield fogs up in the rain.
However, if there is a large drop of water on the inside of the
lens, or if there is water pooled inside the light, contact your
Lexus dealer. LIGHT LOCATION
