When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage to the vehicle. The following
are general precautions which should be
closely observed.
WARNING
∙ Park the vehicle on a level surface, applythe parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Move the shift lever to P (Park).
∙ Be sure the ignition switch is in the OFF or LOCK position when performing any
parts replacement or repairs.
∙ If you must work with the engine running, keep your hands, clothing, hair and tools
away from moving fans, belts and any
other moving parts.
∙ It is advisable to secure or remove any loose clothing and remove any jewelry,
such as rings, watches, etc. before work-
ing on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙ Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position and
the engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
∙ If you must run the engine in an enclosed space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
∙ Never get under the vehicle while it is supported only by a jack. If it is necessary
to work under the vehicle, support it with
safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙ Because the fuel lines on gasoline engine models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel filter or fuel lines.
CAUTION
∙ Do not work under the hood while theengine is hot. Turn the engine off and
wait until it cools down. ∙ Avoid contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle flu-
ids can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid.
∙ Never leave the engine or Continuously Variable Transmission (CVT) related
component harnesses disconnected
while the ignition switch is in the ON
position.
∙ Never connect or disconnect the battery or any transistorized component while
the ignition switch is in the ON position.
This “Do-it-yourself” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine INFINITI service manual is also
available. For additional information, refer to
“Owner’s Manual/Service Manual order in-
formation” in the “Technical and consumer
information” section of this manual.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect warranty coverage. If in doubt about any
servicing, it is recommended that you have it
done by an INFINITI retailer.

Caution symbols for batteryWARNING
1No smoking, No exposed flames, NoSparks Do not expose the battery to electrical sparks, flames or smoking. Hydrogen gas generated by the
battery is explosive. Explosive gases can cause blindness or injury.
2Shield eyes
Handle the battery cautiously. Always wear eye protection glasses to protect against explosion or
battery acid.
3Keep away from children Never allow children to handle the battery. Keep the battery out of the reach of children.
4Battery acidDo not allow battery fluid to contact your skin, eyes, fabrics, or painted surfaces. Sulfuric acid can
cause blindness or severe burns. After handling the battery 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. Battery fluid is acid. If the battery fluid
gets into your eyes or onto your skin, it could cause loss of your eyesight or burns.
5Note operating instructions
Before handling the battery, read this instruction carefully to ensure correct and safe handling.
6Explosive gasHydrogen gas generated by battery fluid is explosive. Explosive gases can cause blindness or injury.
∙ If the battery is labeled "do not open" it is maintenance free and battery fluid should not be checked. It is recommended that you visit a
NISSAN dealer or a qualified specialist workshop to confirm the battery’s performance.
∙ 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 to be 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:1. Installation or extended use of elec-
tronic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. 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 blindness
or injury. Do not allow battery fluid to
contact your skin, eyes, fabrics or painted
surfaces. Sulfuric acid can cause blind-
ness or injury. After touching a battery 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 children. ∙ Do not tip the battery. Keep the vent
caps tight and the battery level.

NOTE:
Do not try to open the top of the battery.
The Type A battery is not equipped with re-
movable vent caps. If low battery fluid is sus-
pected, it is recommended you see a NISSAN
dealer for this service.1. For Type B batteries, remove the vent
caps with a screwdriver as shown. Use a
cloth to protect the battery case.
2. Check the fluid level in each cell. If it isnecessary to add fluid, add only distilled
water to bring the level up to the bottom
of the filler opening. Do not overfill.Re-
install the vent caps.

checks of the battery fluid level.
JUMP STARTING
If jump starting is necessary, refer to “Jump
starting” in the “In case of emergency” section
of this manual. If the engine does not start by
jump starting, the battery may have to be
replaced. It is recommended that you visit an
INFINITI retailer for this service.
