CHARGING THE 12-VOLT BATTERY
The 12-volt battery is charged automatically
using electricity stored in the Li-ion battery.
When the 12-volt battery is being charged, the
charge status indicator light on the instrument
panel flashes. (except when charging the Li-ion
battery or the power switch is in the READY to
drive position.) See “Charging status indicator
lights” in the “CH. Charging” section.
While vehicle is in use
The Li-ion battery charges the 12-volt battery as
necessary when the power switch is in the
READY to drive position or ON position.
The 12-volt battery is not charged in the
following conditions.
.When the power switch is in ACC position.
. When the power switch is in ON position
and shift position is in the N (Neutal)
position.
While the vehicle is not in use
When the EV (Electric Vehicle) system is off for
an extended time, the 12-volt battery may be
automatically charged for a short period of time
on a regular basis.
LI-ION BATTERY HEATER
CAUTION
The Li-ion battery heater does not
operate if the available Li-ion battery
charge is less than approximately 30%
and the charger is not connected to the
vehicle. To help prevent the Li-ion
battery from freezing, do not leave the
vehicle in an environment if tempera-
tures may go below -48F (-208C) unless
the vehicle is connected to a charger.
The Li-ion battery heater helps to prevent the Li-
ion battery from freezing and helps to prevent
significant reductions in the Li-ion battery output
when the temperature is cold. The Li-ion battery
heater automatically turns on when the Li-ion
battery temperature is approximately -48 F
(-208C) or colder. The Li-ion battery heater
automatically turns off when the Li-ion battery
temperture is approximately 148F (-108C) or
higher.
The Li-ion battery heater uses electrical power
from an external source when a charger is
connected to the vehicle. The Li-ion battery
heater uses electrical power from the Li-ion
battery when the charger is not connected to the vehicle.
NOTE:
.
Connect the charger to the vehicle and
place the power switch in the OFF
position when parking the vehicle if
temperatures may go below -48 F
(-208C) . This provides external power
to the Li-ion battery heater when it
operates and does not discharge the
Li-ion battery.
. The charging status indicator lights
illuminate in a specific pattern when
the Li-ion battery heater operates. The
charging status indicator lights use the
same pattern to indicate 12-volt battery
charging, Climate Ctrl. Timer operation
or Remote Climate Control operation.
The charging status indicator lights do
not change if the Li-ion battery heater
operates at the same time as the above
features. See “Charging status indica-
tor lights” in the “CH. Charging” sec-
tion.
. The Li-ion battery heater uses Li-ion
battery power to operate, even if the
vehicle is connected to a charger when:
EV OverviewEV-5

EMERGENCY SHUT-OFF SYSTEM
The emergency shut-off system is activated and
the high-voltage system automatically turns off in
the following conditions:
- Front and side collisions in which the air bags
are deployed.
- Certain rear collisions.
- Certain EV (Electric Vehicle) system malfunc-
tions
For the above collisions and certain other EV
(Electric Vehicle) system malfunctions, the
READY to drive indicator light will turn off. See
“Warning/indicator lights and audible remin-
ders” in the “2. Instruments and controls”
section.
The emergency shut-off activates for the above
collisions to minimize risk of an event that could
cause injury or an accident. If the emergency
shut-off system activates, the EV system may
not be switched to READY to drive position,
contact a NISSAN certified LEAF dealer. Even if
the power switch is switched to READY to drive
position, the system may shut-off suddenly.
Therefore, drive cautiously to the nearest
NISSAN certified LEAF dealer or contact a
NISSAN certified LEAF dealer as soon as
possible.WARNING
.Pay special attention to pedes-
trians. Because there is no engine
noise, pedestrians 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 (Electric Vehicle)
system.
. Be sure to push the P (Park) posi-
tion switch on the selector lever and
apply the parking brake when park-
ing because 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 shift position
other than the P (Park) position.
. Keep the brake pedal depressed
until you are ready to drive. When
the vehicle is in the D (drive) posi-
tion or ECO or R (reverse) position,
if you release the brake pedal and
do not depress 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 accel-
eration 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 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
accelerator pedal is released, the re-
generative brake system provides
some deceleration.
. When you put the shift selector in the
ECO position and take your foot off the
accelerator pedal, more regenerative
brake is applied than in the D (Drive)
position.
. Less deceleration is provided by the
regenerative brake system when the Li-

illuminates, the Li-ion battery charge is too low
for travel. See “Low battery charge warning
light” in the “2. Instruments and controls”
section. Charge the Li-ion battery as soon as
possible.
EV OverviewEV-19

The sound stops when the vehicle stops.
The sound does not stop with the vehicle in the
R (Reverse) position even if the vehicle stops.
WARNING
.If the sound cannot be heard, pe-
destrians may not notice the on-
coming vehicle, which may cause an
accident resulting in serious injury
or death. Immediately contact a
NISSAN certified LEAF for VSP
system inspection.
. If the VSP system warning light
illuminates while the power switch
is in the ON position, or in the
READY to drive position, it may
indicate the VSP system is not
functioning properly. Have the sys-
tem checked by a NISSAN certified
LEAF dealer. See “Approaching Ve-
hicle Sound for Pedestrians (VSP)
system warning light” in the “2.
Instruments and controls” section.

of electric medical device and result
in serious personal injury or death. .
Make sure there is no water or
foreign materials in the charge port,
charge connector or electrical plug,
and that they are not damaged or
affected by rust or corrosion. If any
of these conditions are noticeable,
do not charge the Li-ion battery.
This may result in a short circuit or
electric shock and could cause a fire
which may result in serious perso-
nal injury or death.
. To avoid serious personal injury or
death when the Li-ion battery is
charging, be aware of the following
precautions.
— Do not touch the metal contacts
of the charge port, charge con-
nector or electrical plug.

A lightning strike may back feed
into the charger causing da-
mage and possible personal in-
jury or death.
. Make sure the charge connector is
removed from the charge port be-
fore starting your vehicle. If the
charge connector is only partially engaged and the connector latch is
unlocked, it is possible to place the
EV (Electric Vehicle) in the READY
to drive position.
. Do not plug in or unplug the plug
with wet hands and do not stand in
water, liquid or snow. This may
cause an electric shock which may
result in serious personal injury or
death.
. Do not disassemble or modify the
charge port or the EVSE (Electric
Vehicle Supply Equipment) . This
may cause a fire.
. If you notice an unusual odor or
smoke coming from the vehicle,
stop charging immediately.
. Be careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or get caught in, the
traction motor cooling fan. The cool-
ing fan can start at any time during
charging.
PRECAUTIONS ON CHARGING

.Check by using a cellular phone, smart
phone or personal computer. See LEAF
Navigation System Owner’s Manual.
. Check by using the charging status indicator
light. See “Charging status indicator lights”
later in this section.
NOTE:
. During the charge operation, charge
continues when the power switch is
placed in the ON position.
. The Li-ion battery cannot be charged if
the quick charge connector and the
normal charge connector are con-
nected at the same time. If another
charge connector is connected mid-
charge, charging will stop.
. For safety reasons, it is not possible to
switch to the READY to drive position
while a charge connector is connected.
. During charging, it is possible that the
radio may be inaudible due to noise by
the electromagnetic wave.HOW TO NORMAL CHARGE

WARNING
.Every person who drives or rides in
this vehicle should use a seat belt at
all times. Children should be prop-
erly restrained in the rear seat and,
if appropriate, in a child restraint.
. The seat belt should be properly
adjusted to a snug fit. Failure to do
so may reduce the effectiveness of
the entire restraint system and in-
crease the chance or severity of
injury in an accident. Serious injury
or death can occur if the seat belt is
not worn properly.
. Always route the shoulder belt over
your shoulder and across your
chest. Never put the belt behind
your back, under your arm or across
your neck. The belt should be away
from your face and neck, but not
falling off your shoulder.
. Position the lap belt as low and
snug as possible AROUND THE
HIPS, NOT THE WAIST. A lap belt
worn too high could increase the
risk of internal injuries in an acci-
dent. .
Be sure the seat belt tongue is
securely fastened to the proper
buckle.
. Do not wear the seat belt inside out
or twisted. Doing so may reduce its
effectiveness.
. Do not allow more than one person
to use the same seat belt.
. Never carry more people in the
vehicle than there are seat belts.
. If the seat belt warning light glows
continuously while the power switch
is turned ON with all doors closed
and all seat belts fastened, it may
indicate a malfunction in the sys-
tem. Have the system checked by a
NISSAN certified LEAF dealer.
. No changes should be made to the
seat belt system. For example, do
not modify the seat belt, add mate-
rial, or install devices that may
change the seat belt routing or
tension. Doing so may affect the
operation of the seat belt system.
Modifying or tampering with the
seat belt system may result in
serious personal injury.
