●Wash the vehicle immediatel y 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 you see dead insects, insect drop pings or bird droppings on the paint
• After driving in an area contaminated wi th soot, oily smoke, mine dust, iron pow-
der or chemical substances
• If the vehicle becomes heavily soiled in dust or mud
• If liquids such as benzene and gasoli ne 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 wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic subs tances or scrub with a hard brush.
This may damage the surfaces of the lights.
●Do not apply wax on the surfaces of the lights.
Wax may cause damage to the lenses.
■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 side. When returning the wipers to their
original position, do so from the passenger side first.
■When using an automatic car wash (vehic les with rain-sensing windshield wiper)
Set the wiper switch to the off position.
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
●Do not bring the nozzle tip close to boots (rubber or resin manufactured cover), con-
nectors or the following parts. The parts may be damages if they come into contact
with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
•Brake parts
●Keep the cleaning nozzle at least 11.9 in. (30 cm) away from the vehicle body. Other-
wise resin section, such as moldings and bumpers, may be deformed and damaged.
Also, do not continuously hold the nozzle in the same place.
●Do not spray the lower part of the windshield continuously. If water enters the air con-
ditioning system intake located near the lo wer part of the windshield, the air condi-
tioning system may not operate correctly.
