Maintenance and care
NOTICE
■To prevent paint deterioration
and corrosion on the body
and components (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 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.
■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’s side.
When returning the wipers to their
original position, do so from the
passenger’s side first.
■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 sur-
faces of the lights.
Wax may cause damage to the
lenses.
■Cleaning the radiator grille
Observe the following precautions
to avoid damage to the radiator
grille surface.
●Do not use a hard brush. Use a
soft cloth or sponge to wipe.
●Remove any dirt by using a
neutral detergent. Do not use
waxes or alcohols (e.g. glass
cleaner).
●Wash detergent off with water
after washing the vehicle.
■When using an automatic car
wash
Set the wiper switch to off posi-
tion.
If the wiper switch is in “AUTO”,
the wipers may operate and the
wiper blades may be damaged.
■When using a high pressure
car wash
●When washing the vehicle, do
not spray the camera or its sur-
rounding area directly with a
high pressure washer. Shock
applied from high pressure
water may cause the device to
not operate normally.
●Do not spray water directly on
the radar which is equipped
behind the emblem. Otherwise
it may cause the device to be
damaged.

remove the battery.
When removing the battery, use a
screwdriver of an appropriate size.
