Do not apply water to the inside of the engine compartment. Doing so may cause the
electrical components, etc., to be damaged or catch fire.
■When cleaning the windshield (vehicles with rain-sensing windshield wipers)

If the paint of the rear bumper is chipped or scratched, the system may malfunction. If
this occurs, consult your Lexus dealer.
Set the wiper switch to off.
If the switch is in “AUTO”, the wipers may oper-
ate unexpectedly in the following situations,
and may result in hands being caught or other
serious injuries and cause damage to the wiper
