SWITCHES 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. Automatic headlight leveling system (vehicles with discharge headlight only) NOTICE To prevent the battery from being discharged, do not leave the lights on longer than necessary when the engine is not running. Vehicle position changes according to loading condition, passengers getting on and off, vehicle acceleration and deceleration, etc. However, as the headlight beam level is always maintained automatically by the system at the proper level, your headlights do not dazzle other road users. If this system fails, the warning light in the instrument cluster comes on. If this occurs, have your vehicle checked by your Lexus dealer. If you replace the rear suspension and/or the vehicle height changes, contact your Lexus dealer to check the automatic headlight leveling system and headlight beam level. 30
