●If something bumps against the wind-
shield
●If you directly touch the raindrop sen-
sor body or if something bumps into

become quite hot, do not touch the 
exhaust pipes and rear bumper diffusers 
while the engine is running 
the engine 
When washing the vehicle, be careful not 
to touch the exhaust pipes and rear 
bumper diffusers until they have cooled 
sufficiently, as touching hot exhaust pipes 
and rear bumper diffusers can cause 
burns.
■Precaution regarding the rear

NOTICE
■Application of coatings to the vehicle 
body (vehicles wi th CFRP parts)
Do not apply any kind of coating to the

■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, pollen 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.
