HEADLIGHT SWITCH
12L001
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.
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.
12L002
The automatic light control sensor is on top of the driver’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.
When the headlights come on, the lights automatically turn off about
30 seconds after any of the doors is opened and closed with the
ignition key turned to the ”ACC” or ”LOCK” position.** To turn
them on 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.
When the headlight switch is on with all the doors locked, pushing
the ”LOCK” button on the wireless remote control key turns off the
headlights.
NOTE: *The operating condition or sensitivity can be changed.
**The time before turning off the lights can be changed. Ask your
Lexus dealer for details.

SWITCHES
23 Daytime Running Light System (Canada only)
The headlights turn on 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.
Under the daytime running light system, the headlights turn on at
reduced intensity. Twist the knob to the second clickstop to turn 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)
As the headlight beam level is always maintained automatically at
the proper level in all loading conditions, your headlights do not
dazzle other road users.
If this system fails, the multi information display shows a message
”HEADLIGHT LEVELING”. If this occurs, have your vehicle
checked by Lexus dealer.

HEADLIGHT DIMMER AND TURN
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.
