Automatic car washes
● Fold the mirrors before washing the vehicle. Start washing from the front
of the vehicle. Make sure to and extend the mirrors before driving.
● When having your vehicle washed in an automatic car wash, make sure
beforehand that the car wash is of suitable type to avoid scratches to the
vehicle surface and harm to 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 vehi-
cle from being cleaned properly or result in damage to the rear spoiler.
● Vehicles with CFRP (Carbon Fiber Reinforced Plastic) parts: Do not use
automatic car washes as they may damage the rear wing or its finish.
■ High pressure car washes
● Do not allow the nozzles of the car wash to come within close proximity
of the windows and door frames as water may enter the cabin.
● Before using the car wash, check that the fuel filler lid on your vehicle is
closed properly.
■ Alloy wheels
● Remove any dirt immediately by using a neutral detergent.
● Wash detergent off with water immediately after use.
● To protect the paint from damage, make sure to observe the following
precautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after
driving or parking in hot weather
■ Parts containing resin such as the bumper
Do not scrub with abrasive cleaners.

CAUTION
■To prevent paint deterioration and corrosion on the body and compo-
nents (alloy wheels etc.)
●Wash the vehicle immediately in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If you see coal tar or tree sap on the paint surface
• If you see dead insects, insect droppings or bird droppings on the paint
• After driving in an area contaminated with soot, oily smoke, mine dust,
iron powder or chemical substances
• If the vehicle becomes heavily soiled in 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.
■ Protective film for side sill plates
Make sure to remove the protective film. Failure to do so may cause rust,
depending on conditions.
■ 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 on 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 passenger side. When returning
the wipers to their original position, do so from the passenger side first.

CAUTION
■
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
■ Cleaning the rear bumper cherry red stripe (tS models)
● When using a high pressure car wash (pressure washer) to wash your
vehicle, keep the nozzle a safe distance (11.9 in. [30 cm] or more) from the
stripe. Do not use the high pressure car wash on the same area continu-
ously.
● When using a heated or steam high pressure car wash or extra high-pres-
sure pressure washer, do not point the nozzle directly at the stripe, other-
wise the stripe may come off or be damaged.
● Carefully read the label of a car wash soap before using it, as some car
wash soaps may adversely affect the adhesion strength of the stripe.
● If dirt cannot be removed from the stripe, clean it off using a soft cloth
dampened with a neutral detergent diluted with water.
■ Avoiding damage to the under spoilers (tS models)
● When cleaning the under spoilers, do not use organic substances such as
gasoline, paint thinner, acidic or alkaline solutions, or other detergent.
● The under spoilers may deform if exposed to high temperatures or
extreme heat.

CAUTION
■Cleaning detergents
●Do not use organic substances such as benzene or gasoline, acidic or
alkaline solutions, dye, bleach or other detergent. Doing so may discolor
the vehicle interior or cause streaks or damage to painted surfaces.
● Do not use polish wax or polish cleaner. The instrument panel's or other
interior part’s painted surface may be damaged.
● Do not use a chemical agent containing silicone (highly-polymerized sili-
con compound) when cleaning any of the electrical appliances such as the
air conditioning, all switches and their surrounding areas.
If silicon (highly-polymerized silicon compound) contacts these compo-
nents, it may cause the electrical appliances to malfunction.
■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces.
●Remove any dust, dirt, sand, oil spots etc. on leather surfaces immedi-
ately.
● Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl, plastic, or that contain wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.
■ Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components under the floor of the vehicle, and
may also cause the body to rust.

When removing dirt or dust from the Alcantara® areas
Remove dirt or dust from the Alcantara
® areas by lighting brushing with a
soft brush. If this does not remove the dirt or dust, remove it using adhesive
tape.
CAUTION
■ When soaking up spilled liquids
Do not press down too firmly with the cloth, tissue paper etc., as doing so
may cause the liquid to further penetrate the material, making soaking up
the liquid more difficult.
If the Alcantara® upholstery surface becomes uneven,
lightly brush it with a soft brush.
Allow the surface to dry completely.
■ Oil stains
You will need the following items:
●A cloth that has been dampened with benzene
● A dry cloth
Using a dry cloth or tissue paper, wipe away as much of the
oil as possible to prevent the stained area from expanding.
After patting the area from the outside to the inside from
multiple angles using the cloth dampened with benzene,
soak up the oil and benzene that floats up by patting the
area with a dry cloth.
If the Alcantara
® upholstery surface becomes uneven,
lightly brush it with a soft brush.

WARNING
The engine compartment contains many mechanisms and fluids that may
move suddenly, become hot, or become electrically energized. To avoid death
or serious injury, observe the following precautions.
■
When working in the engine compartment
● Keep hands, clothing, and tools away from the moving fan and engine
drive belt.
● Be careful not to touch the engine, radiator, exhaust manifold, etc. right
after driving as they may be hot. Oil and other fluids may also be hot.
● Do not leave anything that may burn easily, such as paper or rags, in the
engine compartment.
● Do not smoke, cause sparks or expose an open flame to fuel or the bat-
tery. Fuel and battery fumes are flammable.
● Be extremely cautious when working on the battery. It contains poisonous
and corrosive sulfuric acid.
■ When working near the electric cooling fans or radiator grille
Vehicles without a keyless access with push button start system: Be sure the
engine switch is off. With the engine switch in the “ON” position, the electric
cooling fans may automatically start to run if the air conditioning is on and/or
the coolant temperature is high. ( →P. 366)
Vehicles with a keyless access with push button start system: Be sure the
push-button ignition switch is off. With the push-button ignition switch in
“ON” mode, the electric cooling fans may automatically start to run if the air
conditioning is on and/or the coolant temperature is high. ( →P. 366)
■ Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from
getting in the eyes.
CAUTION
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air. Also a backfire could cause a fire in the engine compart-
ment.
