Condensation build-up on the inside of the lens
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional, for more information in the following situations.
Temporary condensation build-up on the inside of the headlight lens does
not indicate a malfunction.
Large drops of water are built up on the inside of the lens.
Water has built up inside the headlight.
Discharge headlights (if equipped)
If voltage to the discharge bulbs is insufficient, the bulbs may not come on,
or may go out temporarily. The discharge bulbs will come on when normal
power is restored.
LED side turn signal lights, tail lights, stop/tail lights, high mounted stop-
light, license plate lights and front position lights (vehicles with discharge
headlights)
The side turn signal lights, tail lights, stop/tail lights, high mounted stop-
light, license plate lights and front position lights (vehicles with discharge
headlights) consist of a number of LEDs. If any of the LEDs burn out, take
your vehicle to any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional to have the light replaced.
Remove the securing bolt and move the
washer fluid filler opening to allow easy
access to the light bulbs.

Maintenance and care
IS250/220d/200d_EE
CAUTION
Replacing light bulbs
Turn off the headlights. Do not attempt to replace the bulb immediately
after turning off the headlights.
The bulbs become very hot and may cause burns.
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.
Fully install light bulbs and any parts used to secure them. Failing 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.
Discharge headlights (if equipped)
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional, before replacing discharge headlights (includ-
ing light bulbs).
Do not touch the high-intensity 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.
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.
To prevent damage or fire
Make sure bulbs are fully seated and locked.

Avoiding a discharged battery
Turn off the headlights and the audio system while the engine is off.
Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
Charging the battery
The electricity stored in the battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects
of certain electrical appliances. If the vehicle is left for a long time, the
battery may discharge, and the engine may be unable to start. (The bat-
tery recharges automatically during driving.)
CAUTION
Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable gas that may be emitted from the battery.
Make sure the jumper cable is connected to the correct terminal and that it
is not unintentionally in contact with any part other than the intended ter-
minal.
Do not allow the jumper cables to come into contact with the “+” and “-”
terminals.
Do not allow open flame or use matches, cigarette lighters or smoke near
the battery.
