2016 NISSAN SENTRA battery

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
●Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. For manual transmission
models, move the shift lever to N (Neu-
tral) . For Continuously Variable Trans-
mission (CVT) models, 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 run-
ning, 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
working on your vehicle.
● Always wear eye protection whenever
you work on your vehicle. ●
If you must run the engine in an en-
closed 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 neces-
sary 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 en-
gine models are under high pressure
even when the engine is off, it is recom-
mended that you visit a NISSAN dealer
for service of the fuel filter or fuel lines.
●
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key 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.
CAUTION
● Do not work under the hood while the
engine 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
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
● Never leave the engine or the transmis-
sion related component harness con-
nector 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 “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
A Genuine NISSAN service manual is also avail-
able. For additional information, refer to “Owner’s
Manual/Service Manual order information” in the
“Technical and consumer information” section of
this manual.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage. If in doubt about any servicing, it
is recommended that you have it done by a
NISSAN dealer.

●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 electronic accessories that consume battery power
when the engine is not running (Phone char-
gers, 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 blind-
ness or injury. Do not allow battery fluid
to contact your skin, eyes, fabrics or
painted surfaces. Sulfuric acid can
cause blindness or injury. After touch-
ing 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.

1. Remove the vent caps with a screwdriver asshown. 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.Reinstall
the vent caps. Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
JUMP STARTING
If jump starting is necessary, refer to “Jump start-
ing” 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 a NISSAN dealer for
this service.

CAUTION
●Do not ground accessories directly to
the battery terminal. Doing so will by-
pass the variable voltage control sys-
tem and the vehicle battery may not
charge completely.
● Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
Your vehicle is equipped with a variable voltage
control system. This system measures the
amount of electrical discharge from the battery
and controls voltage generated by the generator. The current sensor
Ais located near the battery
along the negative battery cable. If you add elec-
trical accessories to your vehicle, be sure to
ground them to a suitable body ground such as
the frame or engine block area.
1. Automatic tensioner pulley
2. Generator pulley
3. Water pump pulley
4. Air conditioner compressor pulley (if so
equipped/Idler pulley (if so equipped)
5. Crankshaft pulley
WARNING
Be sure the ignition switch is in the OFF or
LOCK position before servicing drive belt.
The engine could rotate unexpectedly.
