Lexus SC 430 2002 Manual page 41

When you turn on the headlights, the lights automatically turn
off about 30 seconds after either door is opened and closed
with the ignition switch turned to the "ACC" or "LOCK"
position.* To turn them on again, turn the ignition switch 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.
NOTE: *The time before turning off the lights can be
changed. Ask your Lexus dealer for details.
When the headlight switch is on with both side doors locked
and the trunk closed, pushing the "LOCK" button on the
wireless remote control key turns off the headlights.
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.
