WARNING
The engine cooling system is filled at the
factory with a high-quality, year-round,
antifreeze coolant solution. The antifreeze
solution contains rust and corrosion inhibi-
tors, therefore additional cooling system
additives are not necessary.
•Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused by
high-pressure fluid escaping from the
radiator. For additional information on
precautions, refer to "If your vehicle
overheats"
•The engine coolant reservoir tank is
equipped with a pressure type cap. To
prevent engine damage, use only a
genuine INFINITI pressure cap.
CAUTION
•Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.NIC2833

•Keep the battery surface clean and dry.
Clean the battery with a solution of baking
soda and water.
•Make certain the terminal connections are
clean and securely tightened.
•If the vehicle is not used for 30 days or
longer, disconnect the
-negative battery
terminal cable to prevent discharge.
NOTE
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
•Installation or extended use of electronic
accessories that consume battery power
when the engine is not running (Phone
chargers, GPS, DVD players, etc).
•Vehicle is not driven regularly and/or only
driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
WARNING
•Do not expose the battery to flames, an
electrical spark or a cigarette. Hydrogen
gas generated by the battery is explo-
sive. Explosive gases can cause blind-
ness or injury. Do not allow battery fluid
to contact your skin, eyes, fabrics orpainted surfaces. Sulfuric acid can cause
blindness or injury. After touching a bat-
tery or battery cap, do not touch or rub
your eyes. Thoroughly wash your hands.
If the acid contacts your eyes, skin or
clothing, immediately flush with water
for at least 15 minutes and seek medical
attention.
•Do not operate the vehicle if the fluid in
the battery is low. Low battery fluid can
cause a higher load on the battery which
can generate heat, reduce battery life,
and in some cases lead to an explosion.
•When working on or near a battery, al-
ways wear suitable eye protection and
remove all jewelry.
•Battery posts, terminals and related ac-
cessories contain lead and lead com-
pounds. Wash hands after handling.
•Keep battery out of the reach of chil-
dren.
•Do not tip the battery. Keep the vent
caps tight and the battery level.
