.The A/C-Heater Timer (Climate Ctrl. Timer)
settings cannot be modified while it is
operating. If timer settings are modified
while the A/C-Heater Timer (Climate Ctrl.
Timer) is operating, these changes will be
reflected the next time the A/C-Heater Timer
(Climate Ctrl. Timer) operates.
. When charging is set as the first priority, the
A/C-Heater Timer (Climate Ctrl. Timer) does
not start until 10 segments of the LI-ION
BATTERY AVAILABLE CHARGE GAUGE
are illuminated.
. When the climate control is set as the first
priority, the climate control system will be
turned on as scheduled by the A/C-Heater
Timer (Climate Ctrl. Timer) regardless of the
remaining battery energy.
. Even when the climate control is set as the
first priority, the climate control system will
be turned off when the climate control
spends more electric than the charging Li-
ion battery.
. The Li-ion battery may not charge or may
even become discharged if the A/C-Heater
Timer (Climate Ctrl. Timer) or remote climate
control is used in low ambient temperatures.REMOTE CLIMATE CONTROL
This vehicle incorporates a communication
device that is called a TCU (Telematics Com-
munication Unit). The communication connec-
tion between this unit and NISSAN CARWINGS
Data Center allows for various remote function
services.
Even when away from the vehicle, climate
control can be started by accessing the
NISSAN CARWINGS Data Center website
using a cellular phone or a personal computer.
When operation is started, or at the set start
time, the NISSAN CARWINGS Data Center
accesses the vehicle. When the vehicle receives
a command for remote operation, the climate
control immediately turns ON and operates for
the specified period of time. Confirmation of the
ON/OFF of the climate control operation can be
checked by accessing the website or by e-mail.
Establishing the CARWINGS
TMservice is ne-
cessary before using the service. See LEAF
Navigation System Owner’s Manual.

control system.
SERVICING CLIMATE CONTROL
The climate control system in your NISSAN is
charged with a refrigerant designed with the
environment in mind.This refrigerant will not
harm the earth’s ozone layer. Special char-
ging equipment and lubricant are required when
servicing your NISSAN climate control. Using
improper refrigerants or lubricants will cause
severe damage to your climate control system.
(See “Capacities and recommended lubricants”
in the “9. Technical and consumer information”
section for climate control system refrigerant
and lubricant recommendations.)
A NISSAN certified LEAF dealer will be able to
service your environmentally friendly climate
control system.

Push the switch again to turn the heated
steering wheel system off manually. The indica-
tor light turn off.
NOTE:
.If the surface temperature of the steer-
ing wheel is above 688F (208C) when
the switch is turned on, the system will
not heat the steering wheel. This is not
a malfunction.
. If the outside temperature is low (ap-
proximately 508F (108C) or less) and the
A/C-Heater Timer (Climate Ctrl. Timer)
or Remote Climate Control are used,
the steering wheel heater will automa-
tically operate in the following condi-
tions.
— When using the A/C-Heater Timer
(Climate Ctrl. Timer): Operates from
approximately 15 minutes before
the set departure time until the set
departure time.
— When using Remote Climate Con-
trol: Operates 15 minutes after Re-
mote Climate Control starts.
. The heated steering wheel consumes
less power than the heater and can be
used to either help extend vehicle
range by reducing heater use or to maximize comfort by supplementing
the heater.

CHARGING THE 12-VOLT BATTERY
While vehicle is driven
The Li-ion battery charges the 12-volt battery as
necessary when the power switch is in the
READY to drive position.
While the vehicle is not in use
When the EV (Electric Vehicle) system is off, the
12-volt battery charges automatically for 5
minutes every 5 days.
The charge timing resets to 5 days without
charging the 12-volt battery if:
.The vehicle is placed in the READY to drive
position for more than 5 minutes.
. The Li-ion battery is charged for more than 5
minutes.
When charging the 12-volt battery, the charge
status indicator light on the instrument panel
illuminates. See “Charging status indicator
lights” in the “CH. Charging” section.
LI-ION BATTERY HEATER (if so
equipped)
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, A/C-Heater Timer (Climate
Ctrl. Timer) operation or Remote Cli-
mate 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 indicator lights”
in the “CH. Charging” section.
. The Li-ion battery heater uses Li-ion
battery power to operate, even if the
vehicle is connected to a charger when:

ion battery is fully charged. Regenera-
tive brake is automatically reduced
when the Li-ion battery is fully charged
to prevent the Li-ion battery from
becoming overcharged. Regenerating
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 da-
mage.
. 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 regenerative
brake system operation.
NOISE AND VIBRATION
You might experience the following noise or
vibration as a normal characteristic of this
vehicle.
.Traction motor noise from motor compart-
ment.
. Noise and vibration when releasing and
applying the electric parking brake.
. Water pump and radiator fan noise while
charging. .
Compressor and radiator fan noise when the
A/C-Heater Timer (Climate Ctrl. Timer) or
remote climate control is used.
. Relay operation noise and vibration at start-
up and shut-down of the EV (Electric
Vehicle) system (power switch placed in
the ON and OFF position) .
. Approaching Vehicle Sound for Pedestrians
(VSP) .
WARNING
The EV (Electric Vehicle) system uses a
high voltage current. Failure to follow
the proper handling instructions may
cause serious injury or death. Be sure
to read the “CH. Charging” section and
follow the procedures and guidelines
described.
