2020 NISSAN LEAF battery

4. Regenerated energy (mileage)Displays the amount of regenerated en-
ergy stored in the Li-ion battery in one
trip in terms of distance
If the vehicle has been driven mostly on
downhill roads, more energy is regener-
ated. This may cause the regenerated en-
ergy (mileage) (4) to show a longer distance
than the vehicle was driven or the current
energy economy (2) to show “99.9 miles/
kWh.”
When the
button is pressed while the
ECO Drive Report is shown, the display
switches to the timer display. Either display
will continue to show for another 30 sec-
onds af ter the button is pressed. If the
doors are locked af ter placing the power
switch in the OFF position, the display turns
off before the preset time.
In the “Settings” menu, you can program
the ECO Drive Report to not appear when
the power switch is placed in the OFF posi-
tion. For additional information, refer to “Ve-
hicle information display” in the “Instru-
ments and controls” section of this manual.
WARNING
• Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
• Never leave the vehicle in the READY
to drive mode while the vehicle is
unattended.
• Safe parking procedures require that
both the parking brake be applied
and the vehicle placed in the park po-
sition. Failure to do so could cause
the vehicle to move unexpectedly or
roll away and result in an accident.
• Do not leave children unattended in-
side the vehicle. They could unknow-
ingly activate switches or controls or
make the vehicle move. Unattended
children could become involved in
serious accidents. •
To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require
the assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.
PARKING/PARKING ON HILLS
Starting and driving5-155

You may hear a noise when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the power steering warning light
illuminates while the READY to drive indica-
tor light is on, it may indicate the power
steering system is not functioning properly
and may need servicing. Have the power
steering system checked. It is recom-
mended that you visit a NISSAN certified
LEAF dealer for this service. For additional
information, refer to “Power steering warn-
ing light” in the “Instruments and controls”
section of this manual.
The power assist for steering stops operat-
ing when both the power steering warning
light and READY to drive indicator light are
illuminated. You will still have control of the
vehicle. However, greater steering effort is
needed, especially in sharp turns and at
low speeds.
BRAKE PRECAUTIONS
This vehicle is equipped with two braking
systems:
1. Hydraulic brake system
2. Regenerative brake system
Hydraulic brake system
The hydraulic brake system is similar to the
brakes used on conventional vehicles.
The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
Regenerative brake system
The primary purpose of the regenerative
brake system is to provide some power to
help recharge the Li-ion battery and ex-
tend driving range. A secondary benefit is
“engine braking” that operates based on
battery conditions.
In the D (Drive) range, when the accelerator
is released, the regenerative brake system
provides some deceleration and gener-
ates power for the Li-ion battery. Power is
also generated when the brake pedal is
applied.When you put the shif t lever in the B mode
and take your foot off the accelerator
pedal, more regenerative brake is applied
than in the D (Drive) position. However, dur-
ing high-speed driving you may feel that
regenerative brake provides less decelera-
tion than the engine braking in an ordinary
vehicle. This is normal.
Less deceleration is provided by the regen-
erative brake system when the Li-ion bat-
tery is fully charged. Regenerative brake is
automatically reduced when the Li-ion
battery is fully charged to prevent the Li-ion
battery from becoming overcharged. Re-
generative brake is also automatically re-
duced when the battery temperature is
high/low (indicated by the red/blue zones
on the battery temperature gauge) to pre-
vent 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 regenerative brake system op-
eration.
BRAKE SYSTEM
Starting and driving5-157

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) oper-
ates.
• 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, refer to “Cooling system” in the “Main-
tenance and do-it-yourself ” section of this
manual.
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, refer to “12-volt battery” in the
“Maintenance and do-it-yourself ” section
of this manual.

•NISSAN recommends using only
Genuine NISSAN Emergency Tire
Sealant provided with your vehicle.
Other tire sealants may damage the
valve stem seal which can cause the
tire to lose air pressure. To start your EV system with a booster bat-
tery, the instructions and precautions be-
low must be followed.
Jump starting provides power to the 12-
volt system to allow the electrical systems
to operate. The electrical systems must be
operating to allow the Li-ion battery to be
charged. Jump starting does not charge
the Li-ion battery. The Li-ion battery must
be charged before the vehicle can be
driven.
WARNING
• If done incorrectly, jump starting can
lead to a 12-volt battery explosion,
resulting in severe injury or death. It
could also damage your vehicle.
• Explosive hydrogen gas is always
present in the vicinity of the 12-volt
battery. Keep all sparks and flames
away from the 12-volt battery.
• Do not allow battery fluid to come
into contact with eyes, skin, clothing
or painted surfaces. Battery fluid is a
corrosive sulfuric acid solution that
can cause severe burns. If the fluid
comes into contact with anything,
immediately flush the contacted
area with water. •
Keep the 12-volt battery out of the
reach of children.
• The booster battery must be rated at
12 volt. Use of an improperly rated
battery can damage your vehicle.
• Whenever working on or near a 12-
volt battery, always wear suitable
eye protectors (for example, goggles
or industrial safety spectacles) and
remove rings, metal bands, or any
other jewelry. Do not lean over the
12-volt battery when jump starting.
• Do not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
• Your vehicle has an automatic cool-
ing fan. It could come on at any time.
Keep hands and other objects away
from it.
• Always follow the instructions below.
Failure to do so could result in dam-
age to the DC/DC converter and
cause personal injury.
• Do not attempt to perform a jump
start on the 12-volt battery at the
same time that the Li-ion battery is
being charged. Doing so may dam-
age the vehicle or charging equip-
ment and could cause an injury.
JUMP STARTING
6-10In case of emergency

CAUTION
LEAF cannot be used as a booster ve-
hicle because it cannot supply enough
power to start a gasoline engine. How-
ever, a gasoline engine vehicle can be
used to jump start LEAF's 12-volt bat-
tery.
1. If the booster battery is in another ve-hicle
OB, position the two vehicles (OA)
and
OB) to bring their 12-volt batteries
into close proximity to each other.
Do not allow the two vehicles to touch.
2. Apply the parking brake. If the 12-volt battery is discharged, the
power switch cannot be moved from
the OFF position. Connect the jumper
cables to the booster vehicle
OBbe-
fore pushing the power switch. 3. Push the P (Park) position switch to
place the vehicle in the P (Park) position.
4. Switch off all unnecessary electrical sys- tems (headlights, heater, air conditioner,
etc.).
5. Place the power switch in the OFF position.
6. Ensure vent caps are level and tight.
7. Connect jumper cables in the sequence as illustrated (O1→O2→O3→O4).
LCE2388
In case of emergency6-11

CAUTION
• Always connect positive (+) to posi-
tive (+) and negative (−) to body
ground (for example, as illustrated),
not to the 12-volt battery.
• Make sure the jumper cables do not
touch moving parts in the motor
compartment and that the cable
clamps do not contact any other
metal.
8. Start the engine of the booster vehicle
OB.
9. While the booster vehicle
OBengine is
running, place the EV system in the
READY to drive position.
CAUTION
If the system does not start right away,
push the power switch to the OFF posi-
tion and wait 10 seconds before trying
again.
10. Af ter starting your EV system, carefully disconnect the negative cable and
then the positive cable (
O4→O3→O2
→O1) and keep in the READY to drive
position over 20 minutes to charge the
12-volt battery. 11. If necessary, connect the vehicle to a
charging station or EVSE (Electric Ve-
hicle Supply Equipment) to charge the
Li-ion battery. For additional informa-
tion, refer to the “Charging” section. The
vehicle cannot be driven until the Li-ion
battery is charged.
12. Af ter jump starting your vehicle it is rec- ommended you visit a NISSAN certified
LEAF dealer to have the 12V battery
tested.
NOTE:
If it is not possible to turn the system ON
by following this procedure, it is recom-
mended that you visit a NISSAN certified
LEAF dealer immediately. If the power limitation indicator light
illuminates, the 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 no power is available to drive
the vehicle. Contact Roadside assistance;
refer to a NISSAN Warranty Information
Booklet.
If possible, place the power switch in the
OFF position while waiting for assistance to
prevent discharging the 12-volt battery.
NOTE:
If the Li-ion battery becomes completely
discharged:
• The vehicle is automatically placed in
the ON position and it will not be pos-
sible to switch to the READY to drive
position.
• The vehicle is automatically switched to the N (Neutral) position and it will not
be possible to drive the vehicle.
IF THE LI-ION BATTERY BECOMES
COMPLETELY DISCHARGED
6-12In case of emergency

WARNING
If the vehicle is in the N (Neutral) posi-
tion and the Li-ion battery and the 12-
volt battery become completely dis-
charged, the vehicle cannot be placed
in the P (Park) position. If this occurs,
place suitable blocks at both the front
and back of a wheel to prevent the ve-
hicle from moving. Failure to block a
wheel may allow the vehicle to move
unexpectedly which may result in seri-
ous personal injury or death.
To place the vehicle in the READY to drive
position so the vehicle can be driven,
charge the Li-ion battery until the driving
range on the instrument panel changes
from “---” to a numeric distance.
NOTE:
• Some vibration may occur when the vehicle is stopped in case the Li-ion
battery becomes completely dis-
charged. This is not the malfunction of
the system.
• If the Li-ion battery is completely dis- charged, it is required to charge until
the low battery charge warning light
turns off (white) from on (yellow). Do not attempt to start the system by
pushing the vehicle.
CAUTION
An EV cannot be push-started or tow-
started. Attempting to do so may cause
traction motor damage. When towing your vehicle, all State (Provin-
cial in Canada) and local regulations for
towing must be followed.
Incorrect towing equipment could dam-
age your vehicle. Towing instructions are
available from a NISSAN certified LEAF
dealer. Local service operators are familiar
with the applicable laws and procedures
for towing. To assure proper towing and to
prevent accidental damage to your vehicle,
NISSAN recommends that you have a ser-
vice operator tow your vehicle. It is advis-
able to have the service operator carefully
read the following precautions.
WARNING
• Never ride in a vehicle that is being
towed.
• Never get under your vehicle af ter it
has been lif ted by a tow truck.
CAUTION
• When towing, make sure that the ax-
les, steering system and power train
are in working condition. If any unit is
damaged, dollies must be used.
• Always attach safety chains before
towing.
