Maintenance and care
IS300h_EE(OM53C61E)
CAUTION
■Replacing light bulbs
●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.
●Do not touch the glass portion of the light bulb with bare hands. When it is unavoid-
able to hold the glass portion, use and hold with a clean dry cloth to avoid getting
moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
●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 head-
lights or cause condensation to build up on the lens.
■Discharge headlights (if equipped)
●Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional before replacing the discharge headlights (including light
bulbs).
●Do not touch the discharge headlight’s high voltage socket when the headlights are
turned on.
An extremely high voltage of 30000 V will be discharged and could result in death
or serious injury by electric shock.
●Do not attempt to take apart or repair the headlight bulbs, connectors, power supply
circuits, or related components.
Doing so could result in electric shock and death or serious injury.
■To prevent damage or fire
●Make sure bulbs are fully seated and locked.
●Check the wattage of the bulb before installing to prevent heat damage.
●Vehicles with discharge headlights: While the
headlights are turned on, and for a short time
after they have been turned off, metal compo-
nents at the rear of the headlight assembly will
be extremely hot. To prevent burns, do not
touch these metal components until you are
certain they have cooled down.
