2021 NISSAN LEAF battery

• The charging status indicator lights il-luminate in a specific pattern when the
Li-ion battery warmer operates. The
charging status indicator lights use the
same pattern to indicate 12-volt bat-
tery charging, Climate Ctrl. Timer op-
eration or Remote Climate Control op-
eration (models with Navigation
System). The charging status indicator
lights do not change if the Li-ion bat-
tery warmer operates at the same time
as the above features. For additional
information, see “Charging status indi-
cator lights” (P. CH-49).
• The Li-ion battery warmer uses Li-ion battery power to operate, even if the
vehicle is connected to a charger when:– The vehicle's power switch is in the ON position.
– There is no electrical power being supplied to the charging equipment.
• When the Li-ion battery warmer is al- ready in operation using an external
power source, it will continue to use the
external power even if the power
switch is placed in the ON position. • Vehicle driving range is reduced if the
Li-ion battery warmer operates (Li-ion
battery temperature approximately
-1°F (-17°C) or colder) while driving the
vehicle. You may need to charge the
Li-ion battery sooner than in warmer
temperatures.
• The Li-ion battery requires more time to charge when the Li-ion battery
warmer operates.
• The predicted charging time displayed on the meter and navigation system (if
so equipped) increases when the Li-ion
battery warmer operates.
• Climate control performance is re- duced when using the Climate Ctrl.
Timer or Remote Climate Control
(models with Navigation System) while
the Li-ion battery warmer operates.
• The Li-ion battery may not charge to the expected level using the charging
timer while the Li-ion battery warmer
operates. For models with 62 kWh battery
CAUTION
The Li-ion battery warmer does not op-
erate if the normal charger is not con-
nected to the vehicle. To help prevent
the Li-ion battery from freezing, do not
leave the vehicle in an environment if
temperatures may go below -4°F
(-20°C) unless the vehicle is connected
to a charger.
The Li-ion battery warmer helps to prevent
the Li-ion battery from freezing when the
temperature is cold. The Li-ion battery
warmer automatically turns on when the
Li-ion battery temperature is approxi-
mately -4°F (-20°C) or colder and outside
temperature is approximately -11°F (-24°C)
or colder. The Li-ion battery warmer auto-
matically turns off when the Li-ion battery
temperature is approximately 0°F (-18°C) or
higher, or outside temperature is approxi-
mately -8°F (-22°C) or higher.
The Li-ion battery warmer operates when
the normal charger is connected to the
vehicle, and it automatically uses electrical
power from either the external source or
from the Li-ion battery.
EV-6EV Overview

NOTE:
• Connect the charger to the vehicle andplace the power switch in the OFF po-
sition when parking the vehicle if tem-
peratures may go below -4°F (-20°C).
The Li-ion battery warmer automati-
cally uses electrical power from either
the external source or from the Li-ion
battery, based on the amount of re-
maining Li-ion battery.
• The charging status indicator lights il- luminate in a specific pattern when the
Li-ion battery warmer operates. The
charging status indicator lights use the
same pattern to indicate 12–volt bat-
tery charging, Climate Ctrl. Timer op-
eration or Remote Climate Control op-
eration (models with Navigation
System). The charging status indicator
lights do not change if the Li-ion bat-
tery warmer operates at the same time
as the above features. For additional
information, see “Charging status indi-
cator lights” (P. CH-49). • The automatic climate control auto-
matically turns on when the Li-ion bat-
tery warmer uses electrical power
from the Li-ion battery. This is not a
malfunction. When the Li-ion battery
warmer operates, the temperature in-
side the vehicle may be warmed up.
• The Li-ion battery will be automatically charged when the Li-ion battery
warmer uses electrical power from an
extended source. When outside tem-
perature goes below -4°F (-20°C) for
many days, frequent Li-ion battery
warmer operation may occur, and
more electric power will be charged
from an external source. Do not con-
nect the normal charger to the vehicle
if you do not want to turn on the Li-ion
battery warmer. In this case, do not
leave the vehicle in an environment if
temperatures may go below -4°F
(-20°C).
• When the Li-ion battery warmer is al- ready in operation using an external
source, it will continue to use the exter-
nal power even if the power switch is
placed in the ON position. • The Li-ion battery warmer will stop if
the power switch is placed in the ON
position while the Li-ion battery
warmer is using electrical power from
the Li-ion battery. To turn on the Li-ion
battery warmer again, place the power
switch in the OFF position.
• The Li-ion battery warmer will stop if the charging connector is removed
from the normal charger while the Li-
ion battery warmer is operating. To
turn on the Li-ion battery warmer
again, connect the charging connector
to the vehicle. The Li-ion battery
warmer will operate again af ter about
1 hour.
• The Li-ion battery warmer will stop if the charging connector of the quick
charger is connected to the vehicle
while the Li-ion battery warmer is op-
erating. To turn on the Li-ion battery
warmer again, remove the charging
connector of the quick charger from
the vehicle.
• The Li-ion battery requires more time to charge to the expected level when
the Li-ion battery warmer operates.
EV OverviewEV-7

• The predicted charging time displayedon the meter increases when the Li-ion
battery warmer uses electrical power
from the Li-ion battery.
• The Climate Ctrl. Timer or Remote Cli- mate Control (models with Navigation
System) does not turn on while the Li-
ion battery warmer operates. This is
not a malfunction.
• The charging timer or remote charge (models with Navigation System) does
not turn on while the Li-ion battery
warmer operates. This is not a
malfunction.
• The Li-ion battery may not be charged to the expected level using the charg-
ing timer while the Li-ion battery
warmer operates.
• If the Li-ion battery warmer automati- cally stops because of the Li-ion bat-
tery temperature or outside tempera-
ture change, charging will continue
until the Li-ion battery is fully charged.HIGH-VOLTAGE COMPONENTS
WARNING
• The EV system uses high voltage up
to approximately DC 400 volt. The
system can be hot during and af ter
starting and when the vehicle is shut
off. Be careful of both the high volt-
age and the high temperature. Fol-
low the warning labels that are at-
tached to the vehicle.
• Never disassemble, remove or re-
place high-voltage parts and cables
as well as their connectors because
they can cause severe burns or elec-
tric shock that may result in serious
injury or death. High-voltage cables
are colored orange. The vehicle high
voltage system has no user service-
able parts. It is recommended that
you take your vehicle to a NISSAN
certified LEAF dealer for any neces-
sary maintenance.
HIGH VOLTAGE PRECAUTIONS
EV-8EV Overview

1. Traction motor and reduction gear
2. Traction motor inverter
3. Power delivery module (PDM) (Charger,DC/DC converter, junction box)
4. High-voltage wire harnesses (colored orange) 5. Li-ion battery
6. Service plug
WARNING
In case of a collision:
• If your vehicle is drivable, pull your
vehicle off the road, push the P (Park)
position switch on the shif t lever, ap-
ply the parking brake and turn the EV
system off.
• Check your vehicle to see if there are
exposed high-voltage parts or
cables. For their locations, see “High
voltage components” (P. EV-8). To
avoid personal injury, never touch
high-voltage wiring, connectors, and
other high-voltage parts, such as in-
verter unit and Li-ion battery. An
electric shock may occur if exposed
electric wires are visible when viewed
from inside or outside of your ve-
hicle. Therefore, never touch ex-
posed electric wires.
• If the vehicle receives a strong im-
pact to the floor while driving, stop
the vehicle in a safe location and
check the floor.

ROAD ACCIDENT PRECAUTIONS
EV OverviewEV-9

•Leaks or damage to the Li-ion bat-
tery may result in a fire. If you dis-
cover them, contact emergency ser-
vices immediately. Since the fluid
leak may be lithium manganate from
the Li-ion battery, never touch the
fluid leak inside or outside the ve-
hicle. If the fluid contacts your skin or
eyes, wash it off immediately with a
large amount of water and receive
immediate medical attention to help
avoid serious injury.
• If a fire occurs in the EV, leave the
vehicle as soon as possible. Only use
a type ABC, BC or C fire extinguisher
that is meant for use on electrical
fires. Using a small amount of water
or the incorrect fire extinguisher can
result in serious injury or death from
electrical shock.
• If your vehicle needs to be towed, do
it with the front wheels raised. If the
front wheels are on the ground when
towing, the traction motor may gen-
erate electricity. This may damage
the components of the EV system
and cause a fire. •
If you are not able to safely assess
the vehicle due to vehicle damage, do
not touch the vehicle. Leave the ve-
hicle and contact emergency ser-
vices. Advise first responders that
this is an electric vehicle.
• In the event of an accident that re-
quires body repair and painting, the
Li-ion battery pack and high voltage
parts such as the inverter, including
the wire harness, should be removed
prior to painting. It is recommended
that you visit a NISSAN certified LEAF
dealer for this service. Li-ion battery
packs exposed to heat in the paint
booth will experience capacity loss.
Damaged Li-ion battery packs may
also pose safety risks to untrained
mechanics and repair personnel.
EMERGENCY SHUT-OFF SYSTEM
The emergency shut-off system is acti-
vated and the high-voltage system auto-
matically turns off in the following
conditions:
- Front and side collisions in which the air
bags are deployed.
- Certain rear collisions.
- Certain EV system malfunctions. For the above collisions and certain other
EV system malfunctions, the READY to drive
indicator light will turn off. For additional
information, see “Warning lights, indicator
lights and audible reminders” (P. 2-14).
The emergency shut-off activates for the
above collisions to minimize risk of an
event that could cause injury or an acci-
dent. If the emergency shut-off system ac-
tivates, the EV system may not be switched
to the READY to drive position; it is recom-
mended that you visit a NISSAN certified
LEAF dealer. Even if the power switch is
switched to the READY to drive position, the
system may shut-off suddenly. Therefore,
drive cautiously to the nearest certified re-
pair facility; it is recommended that you
visit a NISSAN certified LEAF dealer for
service.
EV-10EV Overview

WARNING
• Pay special attention to pedestrians.
Because there is no engine noise, pe-
destrians may not know the vehicle
is approaching, moving or about to
move, and may step into the path of
vehicle travel.
• When leaving the vehicle, be sure to
turn off the EV system.
• Be sure to push the P (Park) position
switch on the shif t lever and apply
the parking brake when parking be-
cause the vehicle can move when the
READY to drive indicator light is ON.
When the READY to drive indicator
light is ON, do not leave your vehicle
in a shif t position other than the P
(Park) position.
• Keep the brake pedal depressed until
you are ready to drive. When the ve-
hicle is in the D (Drive) position, B or R
(Reverse) position, if you release the
brake pedal and do not depress the
accelerator, the vehicle will creep and
may start abruptly. This may cause
serious injury or death.NOTE:
• The vehicle cannot run with a dis- charged Li-ion battery. Repeated ac-
celeration consumes more power from
the Li-ion battery than driving at a
steady speed.
• This vehicle is equipped with a regen- erative brake system. The primary pur-
pose of the regenerative brake system
is to provide some power to recharge
the Li-ion battery and extend driving
range. A secondary benefit is “engine
braking” that operates based on Li-ion
battery conditions.
• In the D (Drive) position, when the ac- celerator pedal is released, the regen-
erative brake system provides some
deceleration.
• When you put the shif t lever in the B mode and take your foot off the accel-
erator pedal, more regenerative brake
is applied than in the D (Drive) position. • Less deceleration is provided by the re-
generative brake system when the Li-
ion battery is fully charged. The regen-
erative brake is automatically reduced
when the Li-ion battery is fully charged
to prevent the Li-ion battery from be-
coming overcharged. The regenerative
brake is also automatically reduced
when the battery temperature is high/
low (indicated by the red/blue zones
on the Li-ion battery temperature
gauge) to prevent Li-ion battery
damage.
• The brake pedal should be used to slow or stop the vehicle depending on traffic
or road conditions. The vehicle brakes
are not affected by the regenerative
brake system operation.
