Blade inspection
Contamination of either the windshield
or the wiper blades with foreign matter
can reduce the effectiveness of the
windshield wipers.
Common sources of contamination are
insects, tree sap, and hot wax treatments
used by some commercial car washes. If
the blades are not wiping properly, clean
both the window and the blades with a
good cleaner or mild detergent, and rinse
thoroughly with clean water.
NOTICE
To prevent damage to the wiper blades,
arms or other components, do not:
• Use gasoline, kerosene, paint
thinner, or other solvents on or near
them.
• Attempt to move the wipers
• manually.
• Use non-specified wiper blades.
Information
Commercial hot waxes applied by
automatic car washes have been known to
make the windshield difficult to clean.
Blade replacement
When the wipers no longer clean
adequately, the blades may be worn or
cracked, and require replacement.
NOTICE
To prevent damage to the wiper arms
or other components, do not attempt to
move the wipers manually.
NOTICE
The use of a non-specified wiper blade
could result in wiper malfunction and
failure.
NOTICE
• In order to prevent damage to the
hood and the wiper arms, the wiper
arms should only be lifted when in
the top wiping position.
• Always return the wiper arms to the
windshield before driving.

BATTERY
WARNING
To prevent SERIOUS INJURY or DEATH
to you or bystanders, always follow
these precautions when working near
or handling the battery:
Always read and follow instructions carefully when
handling a battery.
Wear eye protection designed to protect the eyes from acid
splashes.
Keep all flames, sparks, or smoking materials away from
the battery.
Hydrogen is always present in battery cells, is highly
combustible, and may explode
if ignited.
Keep batteries out of reach of children.
Batteries contain sulfuric acid which is highly corrosive. Do
not allow acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush your
eyes with clean water for at least 15
minutes and get immediate medical
attention. If acid gets on your skin,
thoroughly wash the area. If you feel
pain or a burning sensation, get medical
attention immediately.
• When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak. Lift with a
battery carrier or with your hands on
opposite corners.
• Do not attempt to jump start your
vehicle if your battery is frozen.
• NEVER attempt to recharge the
battery when the vehicle’s battery
cables are connected to the battery.
• The electrical ignition system works
with high voltage. NEVER touch
these components with the engine
running or when the Engine Start/
Stop button is in the ON position.
WARNING
CALIFORNIA PROPOSITION 65

to cause cancer. Wash hands after
handling.
NOTICE
• When you do not use the vehicle for a
long time in a low temperature area,
disconnect the battery and keep it
indoors.
• Always charge the battery fully to
prevent battery case damage in low
temperature areas.

Information - For batteries
marked with UPPER and
LOWER
OHI078084L
If your vehicle is equipped with a battery
marked with LOWER (MIN) and UPPER
(MAX) on the side, you should check the
electrolyte level.
The electrolyte level should be between
LOWER (MIN) and UPPER (MAX).
When the electrolyte level is low, add
distilled (or de-mineralized) water. (Never
add sulfuric acids or other electrolyte).
Be careful not to spill distilled (or
demineralized) water over the battery
surface or other adjacent components.

Battery recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
over a short time (because, for
example, the headlamps or interior
lights were left on while the vehicle
was not in use), recharge it by slow
charging (trickle) for 10 hours.
• If the battery gradually discharges
because of high electrical load while
the vehicle is being used, recharge it
at 20-30A for two hours.
WARNING
Always follow these instructions when
recharging your vehicle’s battery to
avoid the risk of SERIOUS INJURY or
DEATH from explosions or acid burns:
• Before performing maintenance or
recharging the battery, turn off all
accessories and stop the engine.
• Keep all flames, sparks, or smoking
materials away from the battery.
• Always work outdoors or in an area
with plenty of ventilation.
• Wear eye protection when checking
the battery during charging.
• The battery must be removed from
the vehicle and placed in a well
ventilated area.
• Watch the battery during charging,
and stop or reduce the charging
rate if the battery cells begin boiling
violently.
