▼Aluminum Wheel Maintenance*
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect t
his coating.
CAUTION
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.
NOTE
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 wate r. Also, be sure to
clean the wheels after driving on dusty
or salted roads to help prevent
corrosion.
Avoid washing your vehicle in an
automatic car wash that uses high-speed
or hard brushes.
▼ Plastic Part Maintenance
When cleaning the plastic lenses of the
lights, do not use gasoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, 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 agents, flush with water
immediately.
If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents
or fluids using a
soft cloth immediately.
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. Otherwise, the
frictional heat generated could result in
deformation of plast ic parts or paint
damage.

Jump-Starting
Jump-starting is dangerous if done incorrectly. So follow the procedure carefully. If you feel
unsure about jump-starting, we strongly recommend that you have a competent service
technician do the work.
WA R N I N G
Follow These Precautions Carefully:
To ensure safe and correct handling of the ba ttery, read the following precautions carefully
before using the battery or inspecting it.
Do not allow the positive () terminal 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 caus e the battery 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 caus e the battery 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 lo w fluid level is dangerous. It may rupture or
explode, causing serious injury.
Connect the negative cable to a good ground point away from the battery:
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 someone.
Route the jumper cables away from parts that will be moving:
Connecting a jumper cable near or to moving pa rts (cooling fans, belts) is dangerous. The
cable could get caught when the engine starts and cause serious injury.

1. Remove the battery cover.
2. Make sure the booster battery is 12 Vand that its negative terminal is
grounded.
3. If the booster battery is in another vehicle, do not allow both vehicles to
touch. Turn off the engine of the
vehicle with the booster battery and all
unnecessary electrical loads in both
vehicles.
4. Connect the jumper cables in the exact
sequence as in the illustration.
Connect one end of a cable to the
positive terminal on the discharged
battery (1).
Attach the other e nd to the positive
terminal on the booster battery (2).
Connect one end of the other cable
to the negative terminal of the
booster battery (3).
Connect the other end to the ground
point indicated in the illustration
away from the discharged battery
(4).
5. Start the engine of the booster vehicle
and run it a few minutes. Then start the
engine of the other vehicle.
6. (With i-ELOOP system)
The i-ELOOP indicator light may flash
after the engine is started. The
indicator light turns off when the
engine is running and the charging is
completed. Make sure the i-ELOOP

If the vehicle is driven with the
i-ELOOP indicator light flashing, a
beep sound is heard.
If the steering wheel is operated with
the i-ELOOP indicator light
flashing, it may feel heavier than
normal, however, this does not
indicate a malfunction. The steering
operation will return to normal when
the i-ELOOP indicator light turns
off.
Do not remove the jumper cables
while the i-ELOOP indicator light is
flashing.
7. When finished, carefully disconnect the cables in the reverse order
described in the illustration.
8. If the battery cover has been removed,
install it in the reverse order of
removal.
NOTE
Verify that the covers are securely
