2006 Lexus RX 400h Owners Manual - Page 100

SWITCHES 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 auxiliary battery from being discharged, do not leave the lights on longer than necessary when the hybrid system is off. Vehicle position changes according to loading condition, passengers getting on and off, vehicle acceleration and deceleration, etc. However, the headlight beam level is always maintained automatically by the system at the proper level so that your headlights do not dazzle other road users. If the system fails, a warning message "HEAD LIGHT LEVELING" appears on the multi−information display, the master warning light comes on and a warning tone sounds. If this occurs, have your vehicle checked by your Lexus dealer. If you replace the rear suspension, contact your Lexus dealer to check the automatic headlight leveling system and headlight beam level. 64
