WARNING
Your vehicle contains a sealed Li-ion
high voltage battery. If the Li-ion bat-
tery is disposed of improperly, there is a
risk of severe burns and electrical
shock that may result in serious injury
or death and there is also a risk of
environmental damage.

illuminates, traction motor output is
limited resulting in reduced vehicle speed.
Stop the vehicle in a safe location before the
Li-ion battery becomes completely dis-
charged and there is no power available to
drive the vehicle. Contact Roadside assis-
tance service shown in your NISSAN
Warranty Information Booklet. See “If the
Li-ion battery becomes completely dis-
charged” in the “6. In case of emergency”
section.

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:

WARNING
.The EV (Electric Vehicle) system
uses high voltage up to approxi-
mately 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. Follow
the warning labels that are attached
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
electric shock that may result in
serious injury or death. High-voltage
cables are colored orange. The
vehicle high voltage system has no
user serviceable parts. Take your
vehicle to a NISSAN certified LEAF
dealer for any necessary mainte-
nance.
