Maintenance and care
■When replacing the front left headlight and parking light bulbs
■Condensation build-up on the inside of the lens
Contact your Lexus dealer for more inform ation 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 in side the headlight.
■Discharge headlights

go out temporarily. The discharge bulbs will come on when normal power is
restored.

washer fluid filler opening to allow easy
access to the light bulbs.
After replacing the bulbs, make sure to
secure the washer fluid filler opening with the
bolt.
