NOTICE
■To prevent paint deterioration and
corrosion on the body and compo-
nents (aluminum wheels etc.)
●Wash the vehicle immediately in the
following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the paint surface
• If dead insects, in sect droppings or
bird droppings are present on the
paint surface
• After driving in an area contaminated with soot, oily smoke, mine dust, iron
powder or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
●If the paint is chip ped or scratched,
have it repaired immediately.
●To prevent the wheels from corroding,
remove any dirt and store in a place
with low humidity when storing the
wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic
substances or scrub with a hard brush.
This may damage the surfaces of the
lights.
●Do not apply wax to the surfaces of the
lights.
Wax may cause damage to the lenses.
■To prevent damage to the windshield
wiper arms
When lifting the wiper arms away from
the windshield, pull the driver side wiper
arm upward first, and repeat for the pas-
senger side. When returning the wipers
to their original position, do so from the
passenger side first.
■When using an automatic car wash
(vehicles with rain-sensing windshield
wipers)
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wip-
ers may operate and the wiper blades
may be damaged.
■When using a high pressure car wash
●When washing the vehicle, do not let
water of the high pressure washer hit
directly or the vicinity of the camera.
Due to the shock from the high pres-
sure water, it is possible the device may
not operate as normal.
●Do not bring the nozzle tip close to
boots (rubber or resin manufactured
cover), connectors or the following
parts. The parts may be damaged if
they come into contact with high-pres-
sure water.
• Traction related parts
•Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at least 11.9
in. (30 cm) away from the vehicle
body. Otherwise resin section, such as
moldings and bumpers, may be
deformed and damaged. Also, do not
continuously hold the nozzle in the
same place.
●Do not spray the lower part of the
windshield continuously. If water
enters the air conditioning system
intake located near the lower part of
the windshield, the air conditioning
system may not operate correctly.
●Do not wash the underside of the vehi-
cle using a high pressure car washer.
