SWITCHES 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. 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. 32
