●Working from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any dirt
and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
●For hard-to-remove marks, use car wash soap and rinse thoroughly
with water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
■Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the front of
the vehicle. Make sure to extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle surface,
parts (wheel, etc.) and harm your vehicle's paint.
●Vehicles with a rear spoiler: In certain automatic car washes, the rear spoiler
may interfere with machine operation. This may prevent the vehicle from
being cleaned properly or result in damage to the rear spoiler.
■High pressure car washes
As water may enter the cabin, do not bring the nozzle tip near the gaps
around the doors or perimeter of the windows, or spray these areas continu-
ously.

WARNING
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may
cause the electrical components, etc. to catch fire.

When washing the vehicle, be careful not to touch the pipes until it has
cooled sufficiently, as touching a hot exhaust pipes can cause burns.

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, insect 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 chipped 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.
■When using a high pressure car wash
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-pressure 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.
