2017 NISSAN LEAF 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 that should be closely observed.
WARNING
• The EV system uses high voltage up to approximately DC 400 volt. The system
can be hot during and after starting
and when the vehicle is shut off. Be
careful of both the high voltage and
the high temperature. Obey the labels
that are attached to the vehicle.
• Never disassemble, remove or replace high-voltage parts and cables as well
as their connectors. High-voltage
cables are colored orange.
• Disassembling, removing or replacing those parts or cables can cause severe
burns or electric shock that may result
in serious injury or death. The vehicle
high-voltage system has no user ser-
viceable parts. Take your vehicle to the
NISSAN certified LEAF dealer for any
necessary maintenance. • Park the vehicle on a level surface,
apply the parking brake securely and
chock the wheels to prevent the ve-
hicle from moving. Push the P (Park)
position switch on the shift lever or
place the vehicle into the N (Neutral)
position.
• If you must work with the EV (Electric vehicle) system is turned on, keep
hands, clothing, hair and tools away
from moving fans and any other mov-
ing parts.
• Make sure that the power switch is in the OFF or LOCK position when per-
forming any part replacement or re-
pairs.
• 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.
• 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, flames and sparks away from the 12-volt battery.
CAUTION
• Do not work under the hood while the motor compartment is hot. Push the
power switch in the OFF position and
wait until it cools down.
• Avoid direct contact with used coolant. Improperly disposed coolant and/or
other vehicle fluids can damage the
environment. Always conform to local
regulations for the disposal of vehicle
fluids.
• Never connect or disconnect the bat- tery or any transistorized component
while the power switch is in the ON
position.
• Your vehicle is equipped with an auto- matic cooling fan. It may come on at
any time without warning, even if the
power switch is not in the ACC, ON or
READY to drive position. To avoid in-
jury, always disconnect the negative
12-volt battery cable before working
near the fan.
• Before performing any electrical main- tenance work on the vehicle such as
the battery, fuses or bulb replacement,
confirm the following:
– The charge connector is removedfrom the vehicle.

section and “Charging status indica-
tor lights” in the “Charging” section
of this manual.
• The power switch is in the OFF posi- tion. Place the power switch in the ON
position and then in the OFF position
to prevent the 12-volt battery auto-
matically being charged by the Li-ion
battery. For additional information, re-
fer to “Charging the 12-volt battery” in
the “EV overview” section of this
manual.
The “Maintenance and do-it-yourself” section
gives instructions regarding only those items that
are relatively easy for an owner to perform. A Genuine NISSAN Service Manual is also avail-
able. For additional information, refer to “Owner’s

Maintenance and do-it yourself8-7

• Keep the 12-volt battery surface clean and dry.Clean the 12-volt battery with a solution of
baking soda and water.
• Make certain the terminal connections are clean and securely tightened.
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 motor 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 12-volt battery to flames or electrical sparks. Hydrogen
gas generated by the 12-volt battery is
explosive. Do not allow 12-volt battery
fluid to contact your skin, eyes, fabrics
or painted surfaces. After touching a
12-volt battery or 12-volt battery cap,
do not touch or rub your eyes. Thor-
oughly wash your hands. If the acid
contacts your eyes, skin or clothing,
immediately flush with water for at
least 15 minutes and seek medical at-
tention.
• Do not operate the vehicle if the fluid in the 12-volt battery is low. Low 12-
volt battery fluid can cause a higher
load on the 12-volt battery which can
generate heat, reduce battery life, and
in some cases lead to an explosion.
• When working on or near a 12-volt battery, always wear suitable eye pro-
tection and remove all jewelry.
• 12-volt battery posts, terminals and re- lated accessories contain lead and
lead compounds. Wash hands after
handling.
• Keep the 12-volt battery out of the reach of children. 1. 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 is nec-essary 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
12-volt battery fluid level.
JUMP STARTING
Jump starting provides power to the 12 volt sys-
tem to allow the electrical systems to operate.
The electrical systems must be operating to allow
the Li-ion battery to be charged. Jump starting
does not charge the Li-ion battery. The Li-ion
battery must be charged before the vehicle can
be driven.
For additional information, refer to “Jump start-
ing” in the “In case of emergency” section of this
manual. If the power switch does not switch to
the READY to drive position by jump starting, the
12-volt battery may have to be replaced. It is
recommended that you visit a NISSAN certified
LEAF dealer for this service.
CLEANING
If your windshield is not clear after using the
windshield washer or if a wiper blade chatters
when running, wax or other material may be on
the blade or windshield.
Clean the outside of the windshield with a washer
solution or a mild detergent. Your windshield is
clean if beads do not form when rinsing with clear
water.
Clean each blade by wiping it with a cloth soaked
in a washer solution or a mild detergent. Then
rinse the blade with clear water. If your windshield
is still not clear after cleaning the blades and
using the wiper, replace the blades.
CAUTION
Worn windshield wiper blades can dam-
age the windshield and impair driver
vision.

CAUTION
• Do not leave the bulb out of the head- light reflector for a long period of time.
Dust, moisture, smoke, etc. entering
the headlight body may affect bulb
performance.
• High-pressure halogen gas is sealed inside the halogen bulb. The bulb may
break if the glass envelope is
scratched or the bulb is dropped.
• Only touch the base when handling the bulb. Never touch the glass envelope.
Touching the glass envelope could sig-
nificantly affect bulb life and/or head-
light performance.
• Aiming is not necessary after replacing the bulb. When aiming adjustment is
necessary, it is recommended that you
visit a NISSAN certified LEAF dealer
for this service.
• Fog may temporarily form inside the lens of the exterior lights in the rain or
in a car wash. A temperature differ-
ence between the inside and the out-
side of the lens causes the fog. This is
not a malfunction. If large drops of
water collect inside the lens, it is rec-
ommended that you visit a NISSAN
certified LEAF dealer for this service. Use the same number and wattage as originally
installed as shown in the chart.
