Contamination of either the windscreen
or the wiper blades with foreign matter
can reduce the effectiveness of the
windscreen 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:

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.
%DWWHULHVFRQWDLQVXOIXULFDFLG
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.

[Do not allow the (+) and (-) jumper
cables to touch. It may cause sparks.

[The battery may rupture or explode
when you jump start with a low or
frozen battery.

[Leaked battery electrolyte due to
repeated driving on sharp curves
(e.g. on circuits) may cause safety
problem. Avoid repeated driving on
sharp curves.
NOTICE
If you connect unauthorised electronic
devices to the battery, the battery may
be discharged. Never use unauthorised
devices.
