Maintenance and Care
• When cleaning the plastic lenses of the lights, do not use gasoline,
kerosene, rectified spirit , paint, thinner, highly acidic detergents, or
strongly alkaline detergents. Other wise, these chemical agents can
discolor or damage the surfaces resulting in a significant loss in
functionality. If plastic parts beco me inadvertently exposed to any of
these chemical age nts, flush with water immediately.
• If plastic parts such as the bu mpers become inadvertently exposed
to chemical agents or fluids such as gasoline, oil, engine coolant, or
battery fluid, it could cause discoloration, stai ning, 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 vehicle or
aimed at one area for an extended period of time, it could deform
plastic parts or damage the paint.
• Do not use wax containing compounds (polish). Otherwise, it could
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 or paint damage.
NOTICE
● Do not use any detergent other than mild detergent. Before using any
detergent, verify the ingredients.
Otherwise, the product could discolor or stain the aluminum wheels.
● Do not use a wire brush or any abrasive cleaner, polishing compound, 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.
● Avoid washing your vehicle in an automatic car wash that uses high-speed
or hard brushes.

Jump-Starting
Jump-starting is dangerous if done incorrectly. So follow the proce-
dure carefully. If you feel unsure about jump-starting, we strongly rec-
ommend that you have a competent service technician do the work.Remove the battery cover.
Make sure the booster battery is 12 V and that its negative terminal
is grounded.
If the booster battery is in another vehicle, do not allow both vehi-
cles to touch. Turn off the engine of the vehicle with the booster bat-
tery and all unnecessary electrical loads in both vehicles.

WARNING
■ Follow These Precautions Carefully
To ensure safe and correct handling of the battery, read the following pre-
cautions carefully before using the battery or inspecting it.
■ Do not allow the positive (+) term inal to contact any other metal
object that could cause sparks
Flames and sparks near open battery cells are dangerous. Hydrogen gas,
produced during normal battery operation, could ignite and cause the bat-
tery to explode. An exploding battery can cause serious burns and injuries.
When working near a battery, do not allow metal tools to contact the positive
(+) or negative (-) terminal of the battery.
■ Keep all flames, including cigarettes, and sparks away from
open battery cells
Flames and sparks near open battery cells are dangerous. Hydrogen gas,
produced during normal battery operation, could ignite and cause the bat-
tery to explode. An exploding battery can cause serious burns and injuries.
■ Do not jump-start a frozen battery or one with a low fluid level
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 injure some-
one.
■ Route the jumper cables away fr om parts that will be moving
Connecting a jumper cable near or to moving parts (cooling fans, belts) is
dangerous. The cable could get caught when the engine starts and cause
serious injury.
NOTICE
Use only a 12 V booster system. You can damage a 12 V starter, ignition
system, and other electrical parts beyond repair with a 24 V power supply
(two 12 V batteries in series or a 24 V motor generator set).
