SWITCHES

HEADLIGHT DIMMER AND TURNSIGNAL SWITCH
SV12010
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.
SV12011
For signaling turns, move the lever up or down in the
conventional manner.
The ignition key must be in the ºONº position.
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.

SWITCHES
29
FRONT FOG LIGHT SWITCH
SV12016
To turn on the front fog lights, turn the switch to the ºONº
position. The front fog lights come on only when the
headlights are on low beam.
When the front fog lights are on, the indicator lights up in the
instrument cluster.
REAR FOG LIGHT SWITCH
SV12017
To turn on the rear fog lights, push the switch. They will
come on when the headlights are turned on.
To turn off the lights, push the switch again. They will go out
when the headlight switch is in the ºOFFº position. After the
rear fog and all other lights are turned off, the rear fog light do
not come on even if you turn on the tail or headlight switch
again.
When the rear fog lights are on, the indicator lights on the upper
side of the rear fog light switch lights up.

REPLACING LIGHT BULBS
The illustration 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.
CAUTION
 To prevent yourself from burning, do not replace the
light bulbs while they are hot.
 Do not disassemble, repair or take apart the low beam
headlight bulbs, connector, power supply circuits
and rotated components. Or you may be injured by
electric shocks. Call your dealer when the headlights
fail to work or have to be replaced or disposed of.
 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.
NOTICE
Only use a bulb of the listed type.

ELECTRICAL COMPONENTS

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 problem because the fogging is
caused by the temperature dif ference between the outside and
inside of the lens, just like the windshield fogged 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
