2013 NISSAN LEAF engine

The LEAF is an electric vehicle. Some of the
vehicle’s systems operate differently and have
different operating characteristics than vehicles
equipped with an internal combustion engine. It is
important to carefully review the entire Owner’s
Manual for this reason. The main difference is the
LEAF is powered by electricity. The LEAF does
not require and it is not capable of using gasoline
like a vehicle powered by a traditional internal
combustion engine. The LEAF uses electricity
stored in the lithium ion (Li-ion) battery. The ve-
hicle Li-ion battery must be charged with electric-
ity before the vehicle can be driven. As the vehicle
operates, the Li-ion battery gradually discharges.
If the Li-ion battery becomes completely dis-
charged, the vehicle will not operate until it is
re-charged. The charging process usually takes
from approximately 30 minutes to 21 hours as
described more fully in this manual.
This vehicle uses two types of batteries. One is
the 12-volt battery that is the same as the battery
in vehicles powered by gasoline engines, the
other is the Li-ion battery (high voltage) .
The 12-volt battery provides power to the vehicle
systems and features such as the audio system,
supplemental restraint systems, headlights and
windshield wipers.The Li-ion battery provides power to the electric
motor (traction motor) that moves the vehicle.
The Li-ion battery also charges the 12-volt bat-
tery.
The vehicle must be plugged in for the Li-ion
battery to be charged. Additionally, the vehicle
system can extend the vehicle range by convert-
ing driving force into electricity that is stored in
the Li-ion battery while the vehicle is decelerating
or being driven downhill. This is called regenera-
tive brake. This vehicle is considered to be an
environmentally friendly vehicle because it does
not emit exhaust gases, such as carbon dioxide
and nitrogen oxide.
WARNING
Your vehicle contains a sealed Li-ion
high voltage battery. If the Li-ion battery
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 dam-
age.
CAUTION
To prevent damage to the Li-ion battery:
Do not expose a vehicle to extreme ambient temperatures for extended
periods.
Do not store a vehicle in temperatures below 13°F (25°C) for over seven
days.
Do not leave your vehicle for over 14 days where the Li-ion battery available
charge gauge reaches a zero or near
zero (state of charge) .
Do not use the Li-ion battery for any other purpose.

EV-2EV Overview

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 reminders
in theInstruments 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 pos-
sible.WARNING
Pay special attention to pedestrians. Because there is no engine noise, pe-
destrians 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) sys-
tem.
Be sure to push the P (Park) position switch on the shift lever and apply the
parking brake when parking 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) posi-
tion.
Keep the brake pedal depressed until you are ready to drive. When the ve-
hicle is in the D (Drive) position 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 se-
rious injury or death.
NOTE:
The vehicle cannot run with a discharged
Li-ion battery. Repeated acceleration con-
sumes more power from the Li-ion battery
than driving at a steady speed.
This vehicle is equipped with a regenera-
tive brake system. The primary purpose 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 accel-
erator pedal is released, the regenerative
brake system provides some decelera-
tion.
When you put the shift lever in the ECO
position (models without navigation sys-
tem) or B position (models with naviga-
tion system) and take your foot off the
accelerator pedal, more regenerative
brake is applied than in the D (Drive) po-
sition.
Less deceleration is provided by the re-
generative brake system when the Li-ion
battery is fully charged. Regenerative
brake is automatically reduced when the

LI-ION BATTERY LIFE
The Li-ion battery’s ability to hold a charge, like all
batteries, decreases with battery age and usage
which results in decreased vehicle range when
compared to the vehicle range when the vehicle
was new. This is normal and expected, and does
not indicate a malfunction of the vehicle or Li-ion
battery.
The Li-ion battery’s ability to hold a charge can be
affected by how you drive the vehicle, store the
vehicle, how you charge the Li-ion battery and
Li-ion battery temperature during vehicle opera-
tion and charging. To maximize vehicle range, NISSAN recom-
mends using the default setting, long distance
mode (100% charge) . To maximize the battery’s
useful life, use the following driving and charging
habits where possible:
Avoid exposing a vehicle to extreme ambient
temperatures for extended periods.
Avoid storing a vehicle in temperatures below 13°F (25°C) for over 7 days.
Avoid leaving your vehicle for over 14 days where the Li-ion battery available charge gauge
reaches a zero or near zero (state of charge) .
Allow the vehicle and Li-ion battery to cool down after use before charging.
Park/store your vehicle in cool locations out of direct sunlight and away from heat sources.
Avoid sustained high battery temperatures (caused, for example, by exposure to very high
ambient temperatures or extending highway
driving with multiple quick charges) .
Use the normal charging or trickle charging methods to charge the Li-ion battery and mini-
mize the use of public Fast Charge or Quick
Charger.
Avoid sustained high battery state of charge (caused, for example, by frequently charging to
100% state of charge and/or leaving the battery above 80% state of charge for long periods of
time) .
Allow the battery charge to be below at least 80% before charging.
Moderate driving.
Use of ECO mode.
If the vehicle will not be used for an extended period of time, charge the Li-ion battery using
the long life mode once every 3 months. Do not
operate the charging timer repeatedly while the
charge connector is connected to the vehicle
after the Li-ion battery charging is completed.
Doing so may discharge the 12-volt battery.
The power of the Li-ion battery can be
checked on the Li-ion battery available charge
gauge. See Li-ion battery available charge
gauge in theInstruments and controls for
details.
LI-ION BATTERY MAINTENANCE
In addition to the regular maintenance recom-
mended by NISSAN, the LEAF requires some
special Li-ion battery inspections.

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,
NISSAN recommends the following driving
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 thevehicle is charging.
Remove unnecessary cargo from the vehicle.
While driving:
Drive in ECO mode – In the ECO position more regenerativebrake is applied when the accelerator pedal
is released in comparison to the D (Drive)
position and more power is provided to the
Li-ion battery.
– The ECO position helps reduce power con- sumption by reducing acceleration when compared to the same accelerator pedal
position in the D (Drive ) position.
– The ECO position reduces the power pro- vided to the heater and air conditioner sys-
tem.
Drive at a constant speed. Maintain cruising speeds with a constant accelerator positions or
by using cruise control when appropriate.
Accelerate slowly and smoothly. Gently press and release the accelerator pedal for accelera-
tion 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 heat- ing or cooling to help reduce power consump-
tion.
Use the air conditioner/heater and close win- dows to reduce drag when cruising at highway
speed.

WARNING
If the READY to drive indicator light is OFF while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
When the power steering warning light illuminates while the READY to drive
indicator light ON, the power assist for
the steering will cease operation. You
will still have control of the vehicle but
the steering will be harder to operate.
The power steering system is designed to pro-
vide power assistance while driving to operate
the steering wheel with less effort.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and help
protect it from getting damaged. While the power
assistance is reduced, steering wheel operation
will become harder. When the temperature of the
power steering system goes down, the power
assistance level will return to normal. Avoid re-
peating such steering wheel operations that
could cause the power steering system to over-
heat. You may hear a noise when the steering wheel is
operated quickly. However, this is not a malfunc-
tion.
If the power steering warning light
illumi-
nates while the READY to drive indicator light is
ON, it may indicate the power steering system is
not functioning properly and may need servicing.
Have the power steering system checked by a
NISSAN certified LEAF dealer. (See Power
steering warning light in theInstruments and
controls section.)
The power assist for steering stops operating
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 sys-
tems:
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 hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Regenerative brake system
The primary purpose of regenerative brake sys-
tem is to provide some power to help recharge
the Li-ion battery and extend driving range. A
secondary benefit is “engine braking” that oper-
ates based on battery conditions.
In the D (Drive) range, when the accelerator is
released, the regenerative brake system provides
some deceleration and generates power for the
Li-ion battery. Power is also generated when the
brake pedal is applied.
When you put the shift lever in the ECO position
and take your foot off the accelerator pedal, more

regenerative brake is applied than in the D (Drive)
position. However, during high-speed driving you
may feel that regenerative brake provides less
deceleration than the engine braking in an ordi-
nary vehicle. This is normal.
Less deceleration is provided by the regenerative
brake system when the Li-ion battery is fully
charged. Regenerative brake is automatically re-
duced when the Li-ion battery is fully charged to
prevent the Li-ion battery from becoming over-
charged. Regenerative brake is also automati-
cally reduced when the battery temperature is
high/low (indicated by the red/blue zones on the
battery temperature gauge) to prevent Li-ion bat-
tery damage.
The brake pedal should be used to slow or stop
the vehicle depending on traffic or road condi-
tions. The vehicle brakes are not affected by
regenerative brake system operation.
NOTE:
When applying the regenerative brakes,
you may hear a sound coming from the
regenerative brake system. This is a nor-
mal operating characteristic of an EV
(Electric vehicle) .
If the power switch position is in a posi-
tion other than ON or READY to drive, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required to
stop the vehicle, and the stopping dis-
tance will be longer.
When depressing the brake pedal, the
braking pedal feel will not be smooth or
may change when the cooperative regen-
erative brake system activates. However,
the electronically controlled brake system
is operating normally and this does not
indicate a malfunction.
Using brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the brakes,
wearing out the brake pads and shoes faster and
will reduce driving range.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and se-
lect ECO position before going down a slope or
long grade. Overheated brakes may reduce brak-
ing performance and could result in loss of ve-
hicle control.
WARNING
While driving on a slippery surface, be careful when braking or accelerating.
Abrupt braking or accelerating could
cause the wheels to skid, which could
result in an accident.
If the brake pedal is depressed with the EV (Electric Vehicle) system OFF,
you may feel an increased brake pedal
effort and a decreased pedal stroke. If
the BRAKE warning light does not illu-
minate and the brake pedal feels like it
has returned to its normal state after
the EV system is started, this indicates
that there is no malfunction and the
vehicle can be operated normally.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, the
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes have dried.
5-20Starting and driving

To start your EV system with a booster battery,
the instructions and precautions below must be
followed.
Jump starting provides power to the 12-volt sys-
tem 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, re-
sulting 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 cor-
rosive sulfuric acid solution that can
cause severe burns. If the fluid comes
into contact with anything, immedi-
ately 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 pro-
tectors (for example, goggles or indus-
trial safety spectacles) and remove
rings, metal bands, or any other jew-
elry. Do not lean over the 12-volt bat-
tery when jump starting.
Do not attempt to jump start a frozen battery. It could explode and cause
serious injury.
Your vehicle has an automatic cooling fan. It could come on at any time. Keep
hands and other objects away from it.
WARNING
Always follow the instructions below. Failure to do so could result in damage
to the DC/DC converter and cause per-
sonal injury.
CAUTION
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 damage the
vehicle or charging equipment and
could cause an injury.
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
battery.
