engine NISSAN LEAF 2014 1.G Owners Manual

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 the “Instruments 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 the battery’s useful life, use the fol-
lowing driving and charging habits where pos-
sible:
• 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 repetitive charging of the Li-ion battery
with high battery state of charge.
• Moderate driving.
• Use of ECO mode.
• If the vehicle will not be used for an extended
period of time, charge the Li-ion battery 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
the “Instruments and controls” for details.

You can remove the antenna if necessary.
Hold the bottom of the antenna and remove by
turning counterclockwise.
CAUTION
• To avoid damaging or deforming the
antenna, be sure to remove the an-
tenna under the following conditions.
– The vehicle enters an automatic car
wash.
– The vehicle enters a garage with a
low ceiling.– The vehicle is covered with a car
cover.
• Always properly tighten the antenna
rod during installation. Otherwise, the
antenna rod may break during vehicle
operation.
CAR PHONE OR CB RADIO
When installing a CB, ham radio or car phone in
your vehicle, be sure to observe the following
precautions; otherwise, the new equipment may
adversely affect the engine control system and
other electronic parts.
WARNING
• A cellular phone should not be used
for any purpose while driving so full
attention may be given to vehicle op-
eration. Some jurisdictions prohibit
the use of cellular phones while driv-
ing.
• If you must make a call while your
vehicle is in motion, the hands free
cellular phone operational mode is
highly recommended. Exercise ex-
treme caution at all times so full atten-
tion may be given to vehicle operation.• If you are unable to devote full atten-
tion to vehicle operation while talking
on the phone, pull off the road to a safe
location and stop your vehicle.
CAUTION
• Keep the antenna as far away as pos-
sible from the electronic control mod-
ules.
• Keep the antenna wire more than 8 in
(20 cm) away from the electronic con-
trol system harnesses. Do not route
the antenna wire next to any harness.
• Adjust the antenna standing-wave ra-
tio as recommended by the manufac-
turer.
• Connect the ground wire from the CB
radio chassis to the body.
• For details, consult a NISSAN dealer.
4-42Heater, air conditioner, audio and phone systems

– 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.• 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 regenerative
brake system. The primary purpose of re-
generative 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 accelerator pedal is re-
leased, the regenerative brake system pro-
vides some deceleration and some power to
the Li-ion battery.
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 un-
attended.
• Do not leave children unattended in-
side the vehicle. They could unknow-
ingly activate switches or controls. Un-
attended children could become
involved in serious accidents.
• Safe parking procedures require that
both the parking brake be applied and
the vehicle placed in the park position.
Failure to do so could cause the ve-
hicle to move unexpectedly or roll
away and result in an accident.
PARKING/PARKING ON HILLS
5-18Starting and driving

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 the “Instruments 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, moreregenerative 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) .
BRAKE SYSTEM
5-20Starting and driving

• 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 se-
rious 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 bat-
tery.
1. If the booster battery is in another vehicle
B,
position the two vehicles (
AandB) 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.
6-10In case of emergency

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
Bbefore 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 systems
(headlights, heater, air conditioner, etc.) .
5. Place the power switch in the OFF position.
6. Remove the vent caps on the 12-volt battery
(if so equipped) . Cover the battery with a
firmly wrung out moist cloth to reduce the
hazard of an explosion.
7. Connect jumper cables in the sequence as
illustrated (
1→2→3→4).
CAUTION
•Always connect positive (+) to positive
(+) 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 com-
partment and that the cable clamps do
not contact any other metal.
8. Start the engine of the booster vehicle
B.9. While the booster vehicle
Bengine is run-
ning, 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. After starting your EV system, carefully dis-
connect the negative cable and then the
positive cable (
4→3→2→1) and
keep the READY to drive position over 20
minutes to charge the 12-volt battery.
11. Replace the vent caps (if so equipped) . Be
sure to dispose of the cloth used to cover
the vent holes because it may be contami-
nated with corrosive acid.
12. If necessary, connect the vehicle to a charg-
ing station or EVSE (Electric Vehicle Supply
Equipment) to charge the Li-ion battery.
(See “Charge” section.) The vehicle can not
be driven until the Li-ion battery is charged.
NOTE:
If it is not possible to turn the system ON by
following this procedure, contact a NISSAN
certified LEAF dealer immediately.If the power limitation indicator light
illumi-
nates, the traction motor output is limited result-
ing in reduced vehicle speed. Stop the vehicle in
a safe location before the Li-ion battery becomes
completely discharged and no power is available
to drive the vehicle. Contact Roadside assis-
tance; see your 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 possible to
switch to the READY position.
•The vehicle is automatically switched to
the N (Neutral) position and it will not be
possible to drive the vehicle.
WARNING
If the vehicle is in the N (Neutral) position
and the Li-ion battery and the 12-volt
battery become completely discharged,
the vehicle can not be placed in the P

the wipers and washers operate properly and
that the wipers do not streak.
Under hood and vehicle
The maintenance items listed here should be
checked periodically.
12-volt battery (for serviceable battery)*:
Check the fluid level in each cell.
It should be between the MAX and MIN lines.
Vehicles operated in high temperatures or undersevere conditions require frequent checks of the
12-volt battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of electronic ac-
cessories that consume battery power when
the engine is not running (Phone chargers,
GPS, DVD players, etc.)
2. Vehicle is not driven regularly and/or only
driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
Brake fluid level*:Make sure that the brake
fluid level is between the MAX and MIN lines on
the reservoir.
Coolant level*:Check the coolant level when
the motor compartment is cold.
Fluid leaks:Check under the vehicle for water
or other fluid leaks after the vehicle has been
parked for a short period of time. Water dripping
from the air conditioner after use is normal. If you
notice any leaks, check for the cause and have it
corrected immediately.Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure that
the hoses have no cracks, deformation, rot or
loose connections.
Underbody:The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan and frame. At
the end of winter, the underbody should be thor-
oughly flushed with plain water, being careful to
clean those areas where mud and dirt may accu-
mulate. For additional information, see “Cleaning
exterior” in the “Appearance and care” section.
Windshield washer fluid*:Check that there is
an adequate amount of fluid in the reservoir.
