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.

Adjust the m

your vehicle in the mirror.
When the inside rear view mirror darkens in ºAUTOº
mode, the outside rear view mirrors also darken to
reduce the reflection of the headlights of the following
vehicle. For details, see ºInside rear view mirrorº on
page 137.
When you push the rear window and outside rear view
mirror defogger switch, the heater panels in the outside
rear view mirrors will quickly clear the mirror surface.
CAUTION
 Do not adjust the mirror while the vehicle is moving.
It may cause the driver to mishandle the vehicle and
an accident may occur, resulting in personal injuries.
Since the mirror surfaces can get hot, keep your
hands off them when the rear window and outside
rear view mirror defogger switch is on.

COMFORT ADJUSTMENT

irror so that you can just see the rear of
your vehicle in the mirror.
Pushing the switch changes the mode between
ºAUTOº and ºDAYº.
The indicator comes on when the ºAUTOº mode is
selected.
ºDAYº mode: The mirror surface is normal.
ºAUTOº mode: If the mirror detects light from the
headlights of the vehicle behind you, the mirror
surface darkens slightly to reduce the reflected
light.
When the inside rear view mirror surface changes, the
outside rear view mirror surfaces will also become
darker.
When the ignition key is inserted and turned on, the
inside rear view mirror always turns on in the ºAUTOº
mode. When the outside air temperature is low, it may take a
little longer for the mirror to darken in response to the
detection of headlights.
CAUTION
Do not adjust the mirror while the vehicle is moving. It
may cause the driver to mishandle the vehicle and an
accident may occur resulting in personal injuries.
