HEADLIGHT SWITCH
12X001a
To turn the lights on, twist the knob on the end of the lever.
FIRST CLICKSTOP: Only the parking, tail, license plate, side
marker and instrument panel lights turn on.
However, if the surroundings are bright and if the instrument
panel light control dial is not turned fully on, the instrument
panel lights do not come on.
SECOND CLICKSTOP: Headlights also turn on.
THIRD CLICKSTOP (“AUTO”): The headlights and all other
lights automatically turn on depending on the darkness of the
surroundings.*
Vehicles sold in U.S.A: When the headlights are on, the
headlight indicator lights up in the instrument cluster.
Vehicles sold in Canada: When the tail lights are on, the tail
light indicator lights up in the instrument cluster. Manually
twist the knob to the second clickstop to turn on
the headlights if they are needed immediately when
entering a dark tunnel, parking structure, etc.
When the headlight switch is turned to the first or second
clickstop, the brightness of the instrument cluster will be
reduced slightly unless the instrument panel light control dial
is turned fully on.
NOTE: *The operating condition or sensitivity can be
changed. Ask your Lexus dealer for details.
12X509
The automatic light control sensor is on top of the passenger’s
side instrument panel.
Do not place anything on the instrument panel, and/or do not
affix anything on the windshield to block this sensor.

SWITCHES
31
When you turn on the headlights, the lights automatically turn
off about 30 seconds after any of the doors is opened and
closed with the ignition switch turned to the “ACC” or “LOCK”\
position.* To
turn them on again, turn the ignition switch to the
“ON” position, or turn the headlight switch off and then twist the
knob until the first or second clickstop. If you are going to park
for over one week, make sure the headlight switch is off.
When the headlight switch is on with all the side doors and
back door locked, pushing the “LOCK” button on the wireless
remote control key turns off the headlights.
NOTE: *The time before turning off the lights can be
changed. Ask your Lexus dealer for details. Daytime Running Light System
The headlights turn on at reduced intensity when the parking
brake is released with the engine started, even with the light
switch in the “OFF” position. They will not go off until the
ignition switch is turned off.
To turn on the other exterior lights and instrument panel lights,
twist the knob to the first clickstop.
Twist
the knob to the second clickstop to turn on the headlights
to full intensity for driving at night.
When setting the knob to the third clickstop (“AUTO”), the
headlights will automatic ally adjust to full intensity and/or turn
on the other lights depending on the darkness of the
surroundings. Likewise, as the surroundings become brighter,
the headlights will turn to reduced intensity, ultimately turning
off the other lights.
NOTICE
To prevent the battery from being discharged, do not
leave the lights on longer than necessary when the
engine is not running.

SWITCHES
32
HEADLIGHT DIMMER AND TURNSIGNAL SWITCH
12X002a
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.
12X003a
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.

SWITCHES
33
FOG LIGHT SWITCH
12X014a
To turn on the fog lights, turn the switch to the “ON”
position. They will come on only when the headlights are
on low beam.
WINDSHIELD WIPER AND WASHERSWITCH
12x004g
 1Automatic control adjuster 2Washer on
To turn the wipers on, move the lever down until you reach
the desired speed setting.
The ignition switch must be in the “ON” position.
There are 3 settings:
“AUTO” position: Automatic operation
The wiper speed is determined by the amount of raindrops
detected by the windshield sensor (shown in the illustration),
and the vehicle speed.
“LO” position: Low speed operation
“HI” position: High speed operation

SWITCHES
34Twist the aut
omatic control adjuster in the “–” direction to
lower the sensitivity, and the “+” direction to boost the
sensitivity.
With the ignition switch turned off, if the windshield sensor is
touched by reason of cleaning the windshield or for any other
reason, either of the following operations may cause automatic
wiper activation.
 Turning the ignition switch on with the wiper lever in the
“AUTO” position.
 Turning the ignition switch on and move the wiper lever
down in the “AUTO” position.
Even with the wiper lever in the “AUTO” position, the system
will switch to intermittent operations if the system malfunctions.
When the system malfunctions, the time interval between
sweeps is shortened as the vehicle speed increases. When
the vehicle speed reaches more than about 20 km/h (12 mph)
with the interval adjuster in “+” position, the time interval
becomes the shortest 1.5 seconds.
The system will turn off if the windshield gets extremely hot (at
more than 90 C or 194F) or cold (at less than –30 C or
–22 F).
CAUTION
Be careful not to get your fingers caught between the
wipers and windshield.
When the wiper lever is in the “AUTO” position with the
ignition switch on, the wipers could operate
automatically in the following cases:
 If you touch the upper center of the windshield
adjacent to the sensor.
 If you wipe the upper center of the windshield
(adjacent to which the sensor is located) with a towel.
 If the windshield vibrates.
 If you touch the sensor.
If you stop the vehicle with the wiper switch in the “LO” position,
the wiper speed automatically changes from low speed to
intermittent operation speed.* This function does not work
when the interval adjuster is in the “+” position.
NOTE: *This feature can be deactivated. Ask your Lexus
dealer for details.

SWITCHES
35
To make the washer squirt, pull the lever toward you and
release it.
If the wiper lever is in the “OFF” position, the wipers will
automatically make 3 wipes and then a single wipe later to
sweep the windshield completely.* The interval between the
3 wipes and the last wipe will depend on the vehicle speed.
The last sweep does not happen if the vehicle speed exceeds
about 170 km/h (106 mph).
NOTE: *The last single wipe can be deactivated. Ask your
Lexus dealer for details.
The low washer fluid warning light in the instrument cluster
comes on when the fluid level in the tank becomes very low.
For information on adding washer fluid, see “Adding washer
fluid” on page 458.
In cold weather, warm the windshield with the defroster before
using the washer. This will help prevent icing, which could
block your vision.
The rear window and outside rear view mirror defogger
automatically turns on when you operate the wipers.
NOTICE
Do not operate the wipers if the windshield is dry. It may
scratch the glass.
When waxing your vehicle, make sure the washer nozzles do
not become blocked. If a nozzle becomes blocked, contact
your Lexus dealer to have the vehicle serviced.
NOTICE
If a nozzle becomes blocked, do not try to clear it with
a pin or other object. The nozzle will be damaged.
