parts as follows:
●Use a soft cloth dampened with
an approximately 5% solution of
neutral detergent and water to
clean the dirt off.
●Wipe the surface with a dry, soft
cloth to remove any remaining
moisture.
●To remove oily deposits, use alco-
hol wet wipes or a similar product.
WARNING

Do not apply water to the inside of
the engine compartment. Doing
so may cause the electrical com-
ponents, etc. to catch fire.
■When cleaning the windshield
(vehicles with rain-sensing
windshield wipers)
Set the wiper switch to off.
If the wiper switch is in “AUTO”,
the wipers may operate unexpect-

ical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gasoline are spilled on the paint
surface
