2021 NISSAN LEAF battery replacement

NOTE:
• If the outside temperature is −13°F(−25°C) or less, the Li-ion battery may
freeze and it cannot be charged or pro-
vide power to run the vehicle. Move the
vehicle to a warm location.
• The capacity of the Li-ion battery in your vehicle to hold a charge will, like
all such batteries, decrease with time
and usage. As the battery ages and ca-
pacity decreases, this will result in a
decrease from the vehicle’s initial mile-
age range. This is normal, expected,
and not indicative of any defect in your
Li-ion battery.
• The Li-ion battery has limited service life, and when its charging capacity
falls below a specific level, the EV sys-
tem warning light will illuminate. Own-
ers should bring their vehicle in for in-
spection and possible battery
replacement.
• It is recommended that you visit a NISSAN certified LEAF dealer for infor-
mation about recycling or disposal of
the Li-ion battery. Do not attempt to
recycle or dispose of the Li-ion battery
yourself.
DRIVING WITH A DISCHARGED
LI-ION BATTERY
When a destination is set in the navigation
system (if so equipped) that exceeds the
available vehicle range, the navigation sys-
tem automatically searches the location of
nearby charging stations. When the nearby
charging station locations are displayed,
charge the Li-ion battery as soon as
possible.
Warning lights illuminate on the instru-
ment panel and messages are displayed
on the vehicle information display to in-
form you that the Li-ion battery charge is
low. Instructions are also displayed on the
navigation system screen (if so equipped)
to direct you to nearby charging stations.
The vehicle's range is very limited when
these warning lights illuminate and mes-
sages are displayed. Follow the instruc-
tions on the navigation system screen (if so
equipped) and immediately charge the ve-
hicle at the nearest charging station.
There are three levels of information that
will be displayed as the Li-ion battery be-
comes discharged: 1. The following warning lights illuminate
on the instrument panel and messages
are displayed on the vehicle information
display at the same time to indicate low
Li-ion battery charge:
• The low battery charge indicator
• The master warning light

box, plug, the EVSE or charge con-
nector is broken, cracked, open,
corroded or shows any other indi-
cations of damage.
– Do not use the EVSE if the plug has
a loose connection with the outlet
or if the outlet is damaged or rusted.
– Before you connect the EVSE, be
sure to check the rated current
shown on the EVSE to ensure that
the outlet and circuit have enough
current capacity to charge your
vehicle safely. If the capacity of
the outlet and circuit is not
enough, wiring may cause over-
heating or a fire.
– If in any doubt about the outlet
and circuit, consult a qualified
electrician.
– The EVSE has parts that may
spark inside. Do not use it where
gasoline, paint, or flammable liq-
uids are used or stored.

it may cause serious injury or death.
CAUTION
• Only charge using a standard AC 220
- 240 volt, 50A dedicated electrical
outlet (for example, do not use an
electric generator). Failure to do so
may cause charging to fail and could
cause damage to the vehicle or the
EVSE due to power surges.
• NISSAN recommends using Genuine
NISSAN charging equipment to
charge the vehicle. Using non-
NISSAN equipment could cause the
Li-ion battery to not charge correctly
and may damage the vehicle or the
EVSE.
Precautions on storage
• Do not store the EVSE in a place exposed to direct sunlight.
• Do not store the EVSE in a place exposed to wind or rain.
• Be sure to store the EVSE with the protec- tive cap on to keep the terminal of the

WARNING
• Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
• The Intelligent Key transmits radio
waves when the buttons are pressed.
The FAA advises the radio waves may
affect aircraf t navigation and com-
munication systems. Do not operate
the Intelligent Key while on an air-
plane. Make sure the buttons are not
operated unintentionally when the
unit is stored for a flight.
• Never leave the Intelligent Key in the
vehicle when you leave the vehicle.
The Intelligent Key system can operate all
the door locks using the remote control
function or pushing the request switch on
the vehicle without taking the key out from
a pocket or purse. The operating environ-
ment and/or conditions may affect the In-
telligent Key system operation.
Be sure to read the following before using
the Intelligent Key system.CAUTION
Be sure to carry the Intelligent Key with
you when operating the vehicle.
The Intelligent Key is capable of receiving
and transmitting radio waves. The Intelli-
gent Key system transmits weak radio
waves from various distances. Environ-
mental conditions may interfere with the
operation of the Intelligent Key system un-
der the following operating conditions:
• When operating near a location where strong radio waves are transmitted, such
as a TV tower, power station and broad-
casting station.
• When in possession of wireless equip- ment, such as a cellular telephone, trans-
ceiver or a CB radio.
• When the Intelligent Key is in contact with or covered by metallic materials.
• When any type of radio wave remote con- trol is used nearby.
• When the Intelligent Key is placed near an electric appliance such as a personal
computer.
• When the vehicle is parked near a parking meter. In such cases, correct the operating condi-
tions before using the Intelligent Key func-
tion or use the mechanical key.
Although the life of the battery varies de-
pending on the operating conditions, the
battery’s life is approximately two years. If
the battery is discharged, replace it with a
new one.
When the Intelligent Key battery is low, the
“Key Battery Low” indicator illuminates in
the vehicle information display. For addi-
tional information, see “Key Battery Low”
(P. 2-34).
Since the Intelligent Key is capable of re-
ceiving radio waves, if the key is lef t near
equipment which transmits strong radio
waves, such as signals from a TV and per-
sonal computer, the battery life may be-
come shorter.
For additional information, see “NISSAN In-
telligent Key® battery replacement” (P. 8-19).
Pay special attention that the vehicle bat-
tery is not completely discharged.

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the power switch to be placed
in the READY to drive position without the
use of the registered key.
If the power switch fails to place the vehicle
into the READY to drive position using the
registered key, it may be due to interfer-
ence caused by another registered key, an
automated toll road device or automated
payment device on the key ring. Restart the
EV system using the following procedure:
1. Leave the power switch in the ON posi- tion for approximately 5 seconds.
2. Place the power switch in the OFF posi- tion and wait approximately 10 seconds.
3. Repeat steps 1 and 2 again.
4. Place the power switch in the READY to drive position while holding the device
(which may have caused the interfer-
ence) separate from the registered key.
If this procedure allows the power
switch to be placed in the READY to drive
mode, NISSAN recommends placing the
registered key on a separate key ring to
avoid interference from other devices. • Make sure that the area around the ve-
hicle is clear.
• Check fluid levels such as coolant, brake fluid, and windshield-washer fluid as fre-
quently as possible.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Check that all doors are closed.
• Position the seat and adjust the head restraints/headrests.
• Adjust the inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of the warning lights when the power switch is pushed to the
ON position. For additional information,
see “Warning lights, indicator lights and
audible reminders” (P. 2-14).
