SIGNAL SWITCH
12L003
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.
12L004
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.

FOG LIGHT SWITCH
12L005
To turn on the fog lights, turn the switch to the ”ON” position.
The fog lights come on only when the headlights are on low beam.

To turn the wipers on, move the lever down until you reach the
desired speed setting.
The ignition key must be in the ”ON” position.
There are 3 settings:
”INT” position: Intermittent operation
”LO” position: Low speed operation
”HI” position: High speed operation
Twist the interval adjuster upward to increase the wiping time
interval between sweeps, and downward to decrease it.
The wiper lever must be in the ”INT” position.

ADDING WASHER FLUID
64L017
If the washer tank becomes nearly empty, add washer fluid.
You may use plain water as washer fluid. However, in cold areas
where temperatures range below the freezing point, use washer fluid
containing antifreeze. This product is available at your Lexus dealer
and most auto parts stores. Follow the manufacturer’s directions for
how much to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute because it
may damage your vehicle’s paint.

readying for a driving (with a full tank).
4. Bounce the vehicle several times.

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
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.
