Maintenance and Care
• When cleaning the plastic lenses of the lights, do not use gasoline,
kerosene, rectified spirit, paint, thinner, highly acidic deter gents, or
strongly alkaline detergents. Ot herwise, these chemical agents can
discolor or damage the surfaces resulting in a significant loss in
functionality. If plastic parts become inadvertently exposed to any of
these chemical age nts, flush with water immediately.
• If plastic parts such as the bumpers become inadvertently exposed to chemical agents or fluids such as gasoline, oil, engine cool ant, or
battery fluid, it could cause di scoloration, staining, or paint peeling.
Wipe off any such chemical agents or fluids using a soft cloth imme-
diately.
• High water temperature and high water pressure car washers are available depending on the type of high pressure car washer
device. If the car washer nozzle is put too close to the vehicl e or
aimed at one area for an extended period of time, it could defo rm
plastic parts or damage the paint.
• Do not use wax containing compounds (polish). Otherwise, it co uld
result in paint damage.
• In addition, do not use an electrical or air tool to apply wax . Other-
wise, the frictional heat generat ed could result in deformation of
plastic parts o r paint damage.
NOTICE
●Do not use any detergent other than mild detergent. Before usin g any
detergent, verify the ingredients.
Otherwise, the product could discolor or stain the aluminum whe els.
● Do not use a wire brush or any abrasive cleaner, polishing comp ound, or
solvent on aluminum wheels. They may damage the coating.
● Always use a sponge or soft cloth to clean the wheels.
Rinse the wheels thoroughly with lukewarm or cold water. Also, be sure to
clean the wheels after driving on dusty or salted roads to help prevent cor-
rosion.

WARNING
■ Follow These Precautions Carefully
To ensure safe and correct handling of the battery, read the fo llowing pre-
cautions carefully before using the battery or inspecting it.
■ Keep flames and sparks away from open battery cells and do
not allow metal tools to contact the positive (+) or negative ( -) terminal
of the battery when working near a battery. Do not allow the positive (+)
terminal to contact the vehicle body
Flames and sparks near open battery cells are dangerous. Hydrog en gas,
produced during normal battery operation, could ignite and cause the bat-
tery to explode. An exploding battery can cause serious burns a nd injuries.
Keep all flames including cigarettes and sparks away from open battery
cells.
■ Keep all flames and sparks away from open battery cells
because hydrogen gas is produced from open battery cells while
charging the battery or adding battery fluid
Flames and sparks near open battery cells are dangerous. Hydrog en gas,
produced during normal battery operation, could ignite and cause the bat-
tery to explode. An exploding battery can cause serious burns a nd injuries.
Keep all flames including cigarettes and sparks away from open battery
cells.
■ Do not jump-start a frozen bat tery or one with a low fluid leve l
Jump-starting a frozen battery or one with a low fluid level is dangerous. It
may rupture or explode, causing serious injury.
■ Connect the negative cable to a good ground point away from the bat-
tery
Connecting the end of the second jumper cable to the negative ( -) terminal
of the discharged battery is dangerous.
A spark could cause the gas around the battery to explode and i njure some-
one.
■ Route the jumper cables away from parts that will be moving
