4-3. Do-it-yourself maintenance
■ Condensation build-up on the inside of the lens
Contact your Lexus dealer for more information in the following situations. Tempo-
rary 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 light bulbs
The parking lights (vehicles with discharge headlights), front side marker lights, side
turn signal lights, tail lights, stop/tail lights, high mounted stoplight, rear side marker
lights and license plate lights consist of a number of LEDs. If any of the LEDs burn
out, take your vehicle to your Lexus dealer to have the light replaced.
■ 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. 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.
● Do not attempt to take apart or repair the low beam headlight bulbs, connectors,
power supply circuits, or related components.
Doing so could result in electric shock and serious injury or death.
