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 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.

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 burning yourself, do not replace the light
bulbs while they are hot.
 Vehicles with discharge headlight—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.

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
