Maintenance and care
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.
■Precautions regarding the
exhaust pipe
Exhaust gasses cause the
exhaust pipe to become quite hot.
When washing the vehicle, be
careful not to touch the pipe until it
has cooled sufficiently, as touch-
ing a hot exhaust pipe can cause
burns.
■Precaution regarding the rear
bumper with Blind Spot Moni-
tor (if equipped)
If the paint of the rear bumper is
chipped or scratched, the system
may malfunction. If this occurs,
consult your Toyota dealer.
NOTICE
■To prevent paint deteriora-
tion and corrosion on the
body and components (alumi-
num 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 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.
