SWITCHES
xxxvii
To turn on the lights again, turn the ignition key 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.
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 automatically 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.
Automatic headlight leveling system (vehicles
with discharge headlight only)
Vehicle position changes according to loading condition,
passengers getting on and off, vehicle acceleration and
deceleration, etc. However, the headlight beam level is always
maintained automatically by the system at the proper level so
that your headlights do not dazzle other road users.
If this system fails, the warning light in the instrument cluster
comes on. If this occurs, have your vehicle checked by your
Lexus dealer.
If you replace the rear suspension and/or the vehicle height
changes, contact your Lexus dealer to check the automatic
headlight leveling system and headlight beam level.

SWITCHES

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.

SWITCHES
xxxix
FOG LIGHT SWITCH
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.
Fog light indicator light in the instrument cluster will tell you that
the fog lights are on.
WINDSHIELD WIPER AND WASHERSWITCH
Variable intermittent windshield wipers
1Interval adjuster2Washer on
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: Variable intermittent operation
“LO” position: Low speed operation
“HI” position: High speed operation

SWITCHES
xlTwist 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.
To make the washer squirt, pull the lever toward you and
release it.
Also, the wipers will automatically operate a couple of times
after the washer squirts even with the lever in the “OFF”

The low washer fluid warning light in the instrument cluster
comes on when the fluid level in the tank becomes nearly
empty. For information on adding washer fluid, see “Adding
washer fluid” on page cdvi.
In cold weather, warm the windshield with the defroster before
using the washer. This will help prevent icing, which could
block your vision.
NOTICE
Do not operate the wipers if the windshield is dry. It may
scratch the glass.
When waxing your vehicle, make sure that the washer nozzles
do not become blocked. If a nozzle becomes blocked, contact
your Lexus dealer to have the vehicle serviced.

Rainsensing windshield wipers
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
“LO” position: Low speed operation
“HI” position: High speed operation
Automatic operation
The wiper speed is determined by the amount of raindrops
and sunlight detected by the automatic wiper control
sensor. You may adjust the automatic wiper control sensitivity by
twisting the automatic control adjuster in the “”
direction, which requires more raindrop volume to start
the wiper, or in the “+” direction, which requires less
raindrop volume to start the wiper.
The sensor is on the inside of the windshield as shown above.
Even if the wiper lever is in the
“AUTO” position, the system will
switch to intermittent operations in the following conditions:
 When the windshield gets extremely cold (at less than
–10 C [14 F])
 When the system malfunctions
However, when the windshield gets extremely hot (at more
than 90 C [194F]), the wipers do not operate even if the wiper
lever is in the “AUTO” position.

SWITCHES
xliiWhen
the ignition switch is turned off with the wiper lever in the
“AUTO” position, and then the ignition switch is turned on
again, the automatic operation may not work even if raindrops
are on the windshield.
In this case, move the lever to another position and return it to
the “AUTO” position again.
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.
