4-3. Do-it-yourself maintenance CAUTION n Replacing light bulbs l Turn off the lights. Do not attempt to replace the bulb immediately after turning off the lights. The bulbs become very hot and may cause burns. l Do not touch the glass portion of the light bulb with bare hands. Hold the bulb by the plastic or metal portion. If the bulb is scratched or dropped it may blow out or crack. l Fully install light bulbs and any parts used to secure them. Failure to do so may result in heat damage, fire, or water entering the headlight unit. This may damage the headlights or cause condensation to build up on the lens. n Discharge headlights (if equipped) l Contact your Lexus dealer before replacing discharge headlights (including light bulbs). l Do not touch the discharge headlight's high voltage socket when the headlights are turned on. An extremely high voltage of 20000 V will be discharged and could result in serious injury or death by electric shock. l Do not attempt to take apart or repair the low beam discharge headlight bulbs, connectors, power supply circuits, or related components. Doing so could result in electric shock and serious injury or death. n To prevent damage or fire Make sure bulbs are fully seated and locked. 564
