2021 NISSAN LEAF cooling

RANGE
The distance you can drive the vehicle
(range) varies considerably depending
upon available charge, weather, tempera-
ture, usage, battery age, topography, and
driving style.
Refer to the Monroney label (window
sticker) for the official EPA range. Your ac-
tual range will vary and could be signifi-
cantly less, either initially or as the battery
ages and with use over time. For additional
information, see “Improve driving range”
(P. EV-22) for information on the factors that
affect vehicle range and how to use the
vehicle to maximize vehicle range.
IMPROVE DRIVING RANGE
Vehicle range depends on a number of
factors.
Actual vehicle range will vary depending
upon:
• Speed,
• Vehicle load,
• Electrical load from vehicle accessories,
• Traffic and road conditions,
• Distance driven without stopping,
• Usage,
• Driving style,• Battery age,
• Weather or temperature,
• Topography,
• Charging habits.
NISSAN recommends the following driv-
ing habits to help maximize vehicle
range:
Before driving:
• Follow recommended periodic
maintenance.
• Keep tires inflated to correct pressure.
• Keep wheels in correct alignment.
• Pre-heat or pre-cool the interior cabin while the vehicle is charging.
• Remove unnecessary cargo from the vehicle.
While driving:
• Drive in ECO mode –– The ECO mode helps reduce power
consumption by reducing acceleration
when compared to the same accelera-
tor pedal position in the D (Drive) posi-
tion (normal mode).
• Drive at a constant speed. Maintain cruis- ing speeds with constant accelerator po-
sitions or by using cruise control when
appropriate. • Accelerate slowly and smoothly. Gently
press and release the accelerator pedal
for acceleration and deceleration.
• Drive at moderate speeds on the highway.
• Avoid extending highway driving with multiple quick charges.
• Avoid frequent stopping and braking. Maintain a safe distance behind other
vehicles.
• Turn off the air conditioner/heater when it is not necessary.
• Select a moderate temperature setting for heating or cooling to help reduce
power consumption.
• Use the air conditioner/heater and close windows to reduce drag when cruising at
highway speed.
• Vehicle range may be substantially re- duced in extremely cold conditions (for
example, -4°F (-20°C)).
• Using the climate control system to heat the cabin when the outside temperature
is below 32°F (0°C) uses more electricity
and affects vehicle range more than
when using the heater when the tem-
perature is above 32°F (0°C).
EFFICIENT USE OF YOUR VEHICLE
EV-22EV Overview

WARNING
• If you use any medical electric de-
vices, such as an implantable cardiac
pacemaker or an implantable cardio-
vascular defibrillator, check with the
electric medical device manufac-
turer concerning the effects that
charging may have on implanted de-
vices before starting the charge op-
eration. Charging may affect the
operation.
• Make sure there is no water or for-
eign 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 personal 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 connec-
tor, electrical plug or Genuine
NISSAN Adapter.
– Do not touch the vehicle and EVSE
when there is lightning.
– Do not pull, twist, bend, step on, or
drag the cable.
• Make sure the charge connector is
removed from the charge port before
starting your vehicle. If the charge
connector is only partially engaged
and the connector latch is unlocked,
it is possible to place the EV in the
READY to drive position.
• Do not touch the plug or the Genuine
NISSAN Adapter if they are wet or
with wet hands. Do not put the plug
or the Genuine NISSAN Adapter in
water, liquid or snow. This may cause
an electric shock which may result in
serious personal injury or death.
• Do not disassemble or modif y the
charge port, the EVSE or the Genuine
NISSAN Adapter. This may cause a
fire or an electric shock which may
result in serious personal injury or
death. •
If you notice an unusual odor, smoke
or abnormal noises 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.
• Do not use extension cords or adapt-
ers unless they are Genuine NISSAN
parts.
• Do not use the Genuine NISSAN
Adapter with any devices except the
Genuine NISSAN EVSE.
• Do not allow an unattended child to
handle or use this product.
• Use the EVSE with outlet and wiring
installed according to the
regulations/standards.
• Pass the lower side belt of the EVSE
case securely through the fastener
on the bottom of the luggage board.
If the case suddenly becomes loose,
it may cause serious injury or death.
PRECAUTIONS ON CHARGING
CH-2Charging

If the BRAKE warning light (red) also illumi-
nates, stop the vehicle immediately and
have the system checked. It is recom-
mended that you visit a NISSAN certified
LEAF dealer for this service. For additional
information, see “Brake system” (P. 5-156).
WARNING
• Pressing the brake pedal when the
power switch position is not in the
ON or READY to drive position and/or
low brake fluid level may increase the
stopping distance and braking will
require greater pedal effort as well as
pedal travel.
•
If the brake fluid level is below the
minimum or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked. It is
recommended that you visit a NISSAN
certified LEAF dealer for this service.
• The cooperative regenerative brake
system may not be working properly
if the brake system warning light illu-
minates when the READY to drive in-
dicator light is ON. If you judge it to be
safe, drive carefully to the nearest
service station for repairs. Otherwise,
have your vehicle towed because
driving could be dangerous.

ing light function for the electronic braking
brake system. When the power switch is
placed in the ON position, the light illumi-
nates for a few seconds. If the warning light
illuminates at any other time, it may indi-
cate that the electronic parking brake sys-
tem is not function properly. Have the sys- tem checked immediately. It is
recommended that you visit a NISSAN cer-
tified LEAF dealer for this service.
Front passenger air bag
status light
The front passenger air bag status light
(located on the center of the instrument
panel) will be lit and the passenger front air
bag and passenger knee airbag will be
turned off depending on how the front pas-
senger seat is being used.
For front passenger air bag status light op-
eration, see “NISSAN Advanced Air Bag Sys-
tem (front seats)” (P. 1-53).
Low tire pressure warning
light
Your vehicle is equipped with a Tire Pres-
sure Monitoring System (TPMS) that moni-
tors the tire pressure of all tires.
The low tire pressure warning light warns
of low tire pressure or indicates that the
TPMS is not functioning properly.
Af ter the power switch is placed in the ON
position, this light illuminates for about 1

2-20Instruments and controls

WARNING
• The air conditioning cooling function
operates only when the power
switch is in the ON position or when
the READY to drive indicator light is
ON.
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to causes severe or possibly
fatal injuries to people or animals. •
Do not use the recirculation mode for
long periods as it may cause the inte-
rior air to become stale and the win-
dows to fog up.
NOTE:
• Odors from inside and outside the ve- hicle can build up in the air conditioner
unit. Odor can enter the passenger
compartment through the vents.
• When parking, set the heater or air conditioner controls to turn off air re-
circulation to allow fresh air into the
passenger compartment. This should
help reduce odors inside the vehicle. The climate control system (air conditioner
and heater functions) can be operated
when the READY to drive indicator light is
illuminated. However, while charging, the
climate control system can be used when
the power switch is in the ON position.
The fan, heater and air conditioning can be
turned on manually, using the timer func-
tion and using the remote climate control
function.

• Drive at a constant speed. Maintain cruis-ing speeds with a constant accelerator
position or by using cruise control when
appropriate.
• Accelerate slowly and smoothly. Gently press and release the accelerator pedal
for acceleration and deceleration.
• Drive at moderate speeds on the highway.
• Avoid frequent stopping and braking. Maintain a safe distance behind other
vehicles.
• Turn off the air conditioner/heater when it is not necessary.
• Select a moderate temperature setting for heating or cooling to help reduce
power consumption.
• Use the air conditioner/heater and close windows to reduce drag when cruising at
a highway speed. • Release the accelerator pedal to slow
down and do not apply the brakes when
traffic and road conditions allow.– 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) posi-
tion, when the accelerator pedal is re-
leased, the regenerative brake system
provides some deceleration and some
power to the Li-ion battery. The ECO Drive Report appears for approxi-
mately 30 seconds af ter placing the power
switch in the OFF position, driving the ve-
hicle for more than 0.3 miles (500 m), and
pressing the
button on the steering
wheel.
ECO DRIVE REPORT
Starting and driving5-153

CAUTION
To prevent damage to the Li-ion bat-
tery: Do not store the vehicle in tem-
peratures below -13°F (-25°C) for over
seven days. If the outside temperature
is -13°F (-25°C) or less, the Li-ion battery
may freeze and it cannot be charged or
provide power to run the vehicle. Move
the vehicle to a warm location.
NOTE:
• Connect the charger to the vehicle and place the power switch in the OFF po-
sition when parking the vehicle if tem-
peratures may go below -4°F (-20°C).
For models with 40 kWh battery
model, this provides external power to
the Li-ion battery warmer (if so
equipped) when it operates and does
not discharge the Li-ion battery. Ve-
hicle driving range is reduced if the Li-
ion battery warmer (if so equipped) op-
erates (Li-ion battery temperature
approximately -4°F (-20°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 (if so equipped) operates. • The predicted charging time displayed
on the meter and navigation system (if
so equipped) increases when the Li-ion
battery warmer (if so equipped)
operates.
• Vehicle range may be substantially re- duced in extremely cold conditions (for
example under -4°F (-20°C)).
• Using the climate control system to heat the cabin when outside tempera-
ture is below 32°F (0°C) uses more elec-
tricity and affects vehicle range more
than when using the heater when the
temperature is above 32°F (0°C).
• Climate control performance is re- duced when using the Climate Ctrl.
Timer or Remote Climate Control while
the Li-ion battery warmer (if so
equipped) operates (for models with
40 kWh battery model). Set only the
charging timer [End Time] when charg-
ing in cold weather. The vehicle auto-
matically determines when to start
charging to fully charge the Li-ion bat-
tery, even if the Li-ion battery warmer
operates. Charging ends before the set
end time if the Li-ion battery is fully
charged.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock be-
comes frozen, heat the key before inserting
it into the key hole or use the remote key-
less entry key fob.
ANTIFREEZE
In the winter when it is possible that the
outside temperature will drop below 32°F
(0°C), check the antifreeze to ensure proper
winter protection. For additional informa-
tion, see “Cooling system” (P. 8-5).
12-VOLT BATTERY
If the 12-volt battery is not fully charged
during extremely cold weather conditions,
the 12-volt battery fluid may freeze and
damage the 12-volt battery. To maintain
maximum efficiency, the 12-volt battery
should be checked regularly. For additional
information, see “12-volt battery” (P. 8-9).
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system. Refill
before operating the vehicle. For additional
information, see “Cooling system” (P. 8-5).
