The automatic light control sensor is on top center of the
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 engine switch off.* To turn them on again, select the
engine switch in “IG− ON” mode, 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 and
the trunk closed, pushing the ”LOCK” button on the electronic
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 engine
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.

sure there is nobody around the power windows. You
must also make sure the heads, hands and other
parts of the bodies of all occupants are kept
completely inside the vehicle. If someone’s neck,
head or hands get caught in a closing window, it
could result in death or serious injury. When anyone
