Maintenance and care
wheels when they are hot, such
as after driving or parking in hot
weather
■Bumpers
Do not scrub with abrasive cleaners.
■Plated portions
If dirt cannot be removed, clean the
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
■When washing the vehicle
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-
edly in the following situations,
and may result in hands being
caught or other serious injuries
and cause damage to the wiper
blades.
Off
AUTO
●When the upper part of the
windshield where the raindrop
sensor is located is touched by
hand
●When a wet rag or similar is
held close to the raindrop sen-
sor
●If something bumps against the
windshield
●If you directly touch the raindrop
sensor body or if something
bumps into the ra indrop sensor
■Precautions regarding the
exhaust pipes
Exhaust gasses cause the
exhaust pipes to become quite
hot.
When washing the vehicle, be
careful not to touch the pipes until
they have cooled sufficiently, as
touching hot exhaust pipes can
cause burns.

WARNING
■Precaution regarding the rear
bumper with Blind Spot Moni-
tor (if equipped)

NOTICE
■To prevent paint deterioration
and corrosion on the body
and components (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 tre e 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 contami- nated with soot, oily smoke,
mine dust, iron powder or chem-
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
●If the paint is chipped or
scratched, have it repaired
immediately.
●To prevent the wheels from cor-
roding, remove any dirt and
store in a place with low humid-
ity 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 sur-
faces of the lights.
Wax may cause damage to the
lenses.
■When using an automatic car
wash (vehicles with rain-
sensing windshield wipers)
Set the wiper switch to off posi-
tion.
If the wiper switch is in “AUTO”,
the wipers may operate and the
wiper blades may be damaged.
■When using a high pressure
car wash
●When washing the vehicle, do
not let water from the high-pres-
sure washer directly hit the
camera or the area around the
camera. Due to the shock from
the high pressure water, it is
possible that the device may not
operate normally.
●Do not bring the nozzle tip close
to boots (rubber or resin manu-
factured cover), or connectors
or the following parts.
The parts may be damaged if
they come into contact with
high-pressure water.
