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
ºACCº or ºL
OCKº position.** To turn them on again, turn
the ignition key to the ºONº 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 ºLOCKº 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.
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 ºOFFº 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 (ºAUTOº),
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 necessarywhen 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 ºHEADLIGHT LEVELINGº. If this occurs,
have your vehicle checked by Lexus dealer.

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 ºONº 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.
