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 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.
Do not apply wax to the surfaces of the lights.
Wax may cause damage to the lenses.
Antenna installation and removal precautions
Before driving, ensure that the antenna is installed.
When the antenna is removed, such as before entering an automatic car
wash, make sure to store it in a suitable place so as not to lose it. Also,
before driving, make sure to reinstall the antenna in its original position.
When using an automatic car wash (vehicles with a rain-sensing wind-
shield wiper)
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wiper may operate and the wiper blade
may be damaged.

CAUTION
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 on the engine compartment:
On hybrid vehicles, make sure that the engine switch is in the “LOCK”
position (vehicles without an electronic key) or the “POWER” switch off
(vehicles with an electronic key) and the “READY” indicator are both off.
Keep hands, clothing and tools away from the moving fan and engine
drive belt.
Be careful not to touch the engine, power control unit (hybrid vehicle), radi-
ator, 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 and 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.
Take care because brake fluid can harm your hands or eyes and damage
painted surfaces. If fluid gets on your hands or in your eyes, flush the
affected area with clean water immediately.
If you still experience discomfort, consult a doctor.
