2606-1. Maintenance and care
WARNING
●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 sensor
●If something bumps against the wind-
shield
●If you directly touch the raindrop sen-
sor body or if something bumps into
the raindrop sensor
■Precautions regarding the exhaust
pipes and rear bumper diffusers
As exhaust gases cause the exhaust
pipes and rear bumper diffusers to
become quite hot, do not touch the
exhaust pipes and rear bumper diffusers
while the engine is running or immedi-
ately after the engine is turned off.
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
bumper with Blind Spot Monitor (if
equipped)
If the paint of the rear bumper is chipped
or scratched, the system may malfunc-
tion. If this occurs, consult your Lexus
dealer.
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, 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.
■To prevent damage or deterioration
of the soft top roof
●Immediately remove any snow that has
accumulated on the soft top roof or
luggage cover.
●If bird droppings etc. are present on
the soft top roof, immediately remove
it.
●When parking the vehicle, avoid direct
sunlight as much as possible.
●If parking the vehicle in a poorly venti-
lated area or a closed area, such as a
garage, ensure that there is adequate
ventilation.
●Do not use wax.
