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 system.
• Be sure to push the P (Park) position
switch on the shif t lever and apply
the parking brake when parking be-
cause 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 shif t position other than the P
(Park) position.
• Keep the brake pedal depressed until
you are ready to drive. When the ve-
hicle is in the D (Drive) position, B or R
(Reverse) position, if you release the
brake pedal and do not depress the
accelerator, the vehicle will creep and
may start abruptly. This may cause
serious injury or death.NOTE:
• The vehicle cannot run with a dis- charged Li-ion battery. Repeated ac-
celeration consumes more power from
the Li-ion battery than driving at a
steady speed.
• 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) position, when the ac- celerator pedal is released, the regen-
erative brake system provides some
deceleration.
• When you put the shif t lever in the B mode and take your foot off the accel-
erator pedal, more regenerative brake
is applied than in the D (Drive) position. • Less deceleration is provided by the re-
generative brake system when the Li-
ion battery is fully charged. The regen-
erative brake is automatically reduced
when the Li-ion battery is fully charged
to prevent the Li-ion battery from be-
coming overcharged. The regenerative
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 dam-
age.
• 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 the 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 the motorcompartment.
• Water pump and radiator fan noise while charging.
EV CHARACTERISTICS
EV OverviewEV-11

• Using the climate control system to heatthe 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).
• When it is cold, use the steering wheel heater in substitution for the heater/air
conditioner. The steering wheel heater
consumes less power than the heater/
air conditioner.
• 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 is released,
the regenerative brake system pro-
vides some deceleration and some
power to the Li-ion battery.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 ve-
hicle range when the vehicle was new. This
is normal and expected, and does not indi-
cate 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 ve-
hicle, store the vehicle, how you charge the
Li-ion battery and Li-ion battery tempera-
ture during vehicle operation and charging.
To maximize the battery's useful life, use
the following driving and charging habits
where possible:
• Avoid exposing a vehicle to extreme am- bient temperatures for extended periods.
• Avoid storing a vehicle in temperatures below −13°F (−25°C) for more than seven
days.
• Avoid leaving your vehicle for more than 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 af ter use before charging. • Park/store your vehicle in cool locations
out of direct sunlight and away from heat
sources.
• Avoid sustained high battery tempera- tures (caused, for example, by exposure
to very high ambient temperatures or ex-
tending highway driving with multiple
quick charges [if so equipped]) .
• Use the normal charging or trickle charg- ing methods to charge the Li-ion battery
and minimize the use of public Fast
Charge or Quick Charger.
• Moderate driving.
• Use of ECO mode.
• Do not operate the charging timer re- peatedly while the charge connector is
connected to the vehicle af ter 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. For additional information,
refer to “Li-ion battery available charge
gauge” in the “Instruments and controls”
section of this manual.
EV OverviewEV-23

The READY to drive indicator light will turn
off in the following conditions.
• Certain EV system malfunctions.
• The READY to drive indicator light turnsoff immediately before the Li-ion battery
is completely discharged. If the Li-ion bat-
tery becomes completely discharged,
the vehicle must be charged in order to
be driven. For additional information, re-
fer to “Low battery charge indicator” in
this section.
Security
indicator light
This light blinks when the power switch is in
the ACC, OFF or LOCK position. This func-
tion indicates the security system
equipped on the vehicle is operational.
If the security system is malfunctioning,
this light will remain on while the power
switch is in the ON position. For additional
information, refer to “Security systems” in
this section.
Slip indicator light
This indicator light will blink when the VDC
system or the traction control system is
operating, thus alerting that the vehicle is nearing its traction limits. The road surface
may be slippery.
You may feel or hear the system working;
this is normal. The light will blink for a few
seconds af ter the VDC system stops limit-
ing wheel spin.
The indicator light also comes on when
you place the power switch in the ON posi-
tion.
The light will turn off af ter approximately 2
seconds if the system is operational. If the
light does not come on, have the system
checked. It is recommended that you visit a
NISSAN certified LEAF dealer for this ser-
vice.
Turn signal/hazard
indicator lights
This light flashes when the turn signal
switch lever or hazard switch is turned on.
Vehicle Dynamic Control
(VDC) OFF indicator light
This light illuminates when the Vehicle Dy-
namic Control (VDC) is turned off in the
vehicle information display. This indicates
that the VDC system is not operating. For
additional information, refer to “Vehicle Dy-namic Control (VDC) system” in the “Start-
ing and driving” section of this manual.
AUDIBLE REMINDERS
Brake pad wear warning
The disc brake pads have audible wear
warnings. When a brake pad requires re-
placement, it will make a high pitched
scraping sound when the vehicle is in mo-
tion. This scraping sound will first occur
only when the brake pedal is depressed.
Af ter more wear of the brake pad, the
sound will always be heard even if the
brake pedal is not depressed. Have the
brakes checked as soon as possible if the
warning sound is heard.
Electric shif t control system
reminder chime
If an improper shif t operation is performed,
for safety reasons a chime will sound and
at the same time, depending on the condi-
tions, the operation will be canceled or the
shif t position will switch to the N (Neutral)
position.
For additional information, refer to “Driving
the vehicle” in the “Starting and driving” sec-
tion of this manual.
2-24Instruments and controls

The dynamic driver assistance switch is
used to temporarily turn on and off the
Intelligent Lane Intervention (I-LI) and Intel-
ligent Blind Spot Intervention (I-BSI) sys-
tems that are activated using the settings
menu of the vehicle information display.
The I-LI and I-BSI systems must be turned
on with the dynamic driver assistance
switch every time the power switch is
placed in the ON position.
The I-LI system warns the driver with a
warning and a chime, and helps assist the
driver to return the vehicle to the center of
the traveling lane by applying the brakes to
the lef t or right wheels individually (for ashort period of time). For additional infor-
mation, refer to “Intelligent Lane Interven-
tion (I-LI)” in the “Starting and driving” sec-
tion and “Vehicle information display” in the
“Instruments and controls” section of this
manual.
The I-BSI system helps alert the driver of
other vehicles in adjacent lanes when
changing lanes, and helps assist the driver
to return the vehicle to the center of the
traveling lane. For additional information,
refer to “Intelligent Blind Spot Intervention
(I-BSI)” in the “Starting and driving” section
of this manual.
The Steering Assist switch is used to en-
able and disable the Steering Assist sys-
tem that is activated using the settings
menu of the vehicle information display.
The Steering Assist system controls the
steering system, when ProPILOT Assist is
engaged, to help keep your vehicle near
the center of the lane when driving. For
additional information, refer to “ProPILOT
Assist" and “Intelligent Lane Intervention (I-
LI)” in the “Starting and driving” section of
this manual.

Seat belts help reduce the risk of injury in
collisions and rollovers.In a rollover crash,
an unbelted or improperly belted person
is significantly more likely to be injured
or killed than a person properly wearing
a seat belt.
OFF-ROAD RECOVERY
While driving, the right side or lef t side
wheels may unintentionally leave the road
surface. If this occurs, maintain control of
the vehicle by following the procedure be-
low. Please note that this procedure is only
a general guide. The vehicle must be driven
as appropriate based on the conditions of
the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheel with both hands and try to hold a
straight course.
4. When appropriate, slowly release the ac- celerator pedal to gradually slow the
vehicle. 5. If there is nothing in the way, steer the
vehicle to follow the road while the ve-
hicle speed is reduced. Do not attempt
to drive the vehicle back onto the road
surface until the vehicle speed is
reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return
to the road surface. When all tires are on
the road surface, steer the vehicle to
stay in the appropriate driving lane.
• If you decide that it is not safe to return the vehicle to the road surface based
on vehicle, road or traffic conditions,
gradually slow the vehicle to a stop in
a safe place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by driving
on under-inflated tires.
Rapid air pressure loss can affect the han-
dling and stability of the vehicle, especially
at highway speeds. Help prevent rapid air pressure loss by
maintaining the correct air pressure and
visually inspecting the tires for wear and
damage. For additional information, refer
to “Wheels and tires” in the “Maintenance
and do-it-yourself ” section of this manual.
If a tire rapidly loses air pressure or “blows-
out” while driving, maintain control of the
vehicle by following the procedure below.
Please note that this procedure is only a
general guide. The vehicle must be driven
as appropriate based on the conditions of
the vehicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a
collision and result in personal injury.
•
The vehicle generally moves or pulls
in the direction of the flat tire.
• Do not rapidly apply the brakes.
• Do not rapidly release the accelerator
pedal.
• Do not rapidly turn the steering
wheel.
5-8Starting and driving

N (Neutral)
Neither forward nor reverse gear is en-
gaged. The vehicle can be placed in the
READY to drive position in this position.
Do not shif t to the N (Neutral) position while
driving. The regenerative brake system
does not operate in the N (Neutral) position.
However, the vehicle brakes will still stop
the car.
D (Drive)
Use this position for all normal forward
driving.If the vehicle is placed in the D
(Drive) position while reversing, the
chime will sound and the vehicle will
switch into the N (Neutral) position. B mode
The B mode engages the regenerative
braking system more aggressively on
downhill slopes, and helps reduce brake
use. It is activated by moving the shif t lever
lef t and down. The shif t lever will then re-
turn to the center position. For additional
information, refer to “Brake system” in this
section.WARNING
• Be sure the parking brake is released
before driving. Failure to do so could
cause brake failure and lead to an
accident.
• Do not release the parking brake
from outside the vehicle.
• 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.
• When leaving the vehicle, apply the
parking brake and push the P (Park)
position switch on the shif t lever.

WARNING
Failure to follow the warnings and in-
structions for proper use of the I-LI sys-
tem could result in serious injury or
death.
• The I-LI system will not steer the ve-
hicle or prevent loss of control. It is
the driver’s responsibility to stay
alert, drive safely, keep the vehicle in
the traveling lane, and be in control of
the vehicle at all times. •
The I-LI system is primarily intended
for use on well-developed freeways
or highways. It may not detect the
lane markers in certain road,
weather, or driving conditions.
The I-LI system must be turned on with the
ProPILOT Assist switch on the steering
wheel (models with ProPILOT Assist) or the
dynamic driver assistance switch (models
without ProPILOT Assist) every time the
power switch is placed in the ON position.
The I-LI system will operate when the ve-
hicle is driven at speeds of approximately
37 mph (60 km/h) and above, and only
when the lane markings are clearly visible
on the road.
The I-LI system warns the driver when the
vehicle has lef t the center of the traveling
lane with an indicator in the vehicle infor-
mation display and a steering vibration.
The system helps assist the driver to return
the vehicle to the center of the traveling
lane by applying the brakes to the lef t or
right wheels individually (for a short period
of time). The I-LI system monitors the lane markers
on the traveling lane using the camera unit
OAlocated above the inside mirror.

INTELLIGENT LANE INTERVENTION
(I-LI)
Starting and driving5-31

I-LI SYSTEM OPERATION
The I-LI system operates above approxi-
mately 37 mph (60 km/h). When the vehicle
approaches either the lef t or the right side
of the traveling lane, the steering wheel will
vibrate and the LDW indicator in the vehicle
information display will blink to alert the
driver. Then, the I-LI system will automati-
cally apply the brakes for a short period of
time to help assist the driver to return the
vehicle to the center of the traveling lane.
To turn on the I-LI system, push the ProPI-
LOT Assist switch on the steering wheel
(models with ProPILOT Assist) or dynamic
driver assistance switch (models without
ProPILOT Assist). The I-LI indicator will illu-
minate. Push the ProPILOT Assist switch
(models with ProPILOT Assist) or dynamic
driver assistance switch (models without
ProPILOT Assist) again to turn off the I-LI
system. The I-LI indicator will turn off.

5-32Starting and driving

–On roads where there are sharply
contrasting objects, such as shad-
ows, snow, water, wheel ruts,
seams or lines remaining af ter
road repairs. (The I-LI system
could detect these items as lane
markers.)
– On roads where the traveling lane
merges or separates.
– When the vehicle’s traveling direc-
tion does not align with the lane
marker.
– When traveling close to the ve-
hicle in front of you, which ob-
structs the lane camera unit de-
tection range.
– When rain, snow or dirt adheres to
the windshield in front of the lane
camera unit.
– When the headlights are not
bright due to dirt on the lens or if
the aiming is not adjusted
properly.
– When strong light enters the lane
camera unit (for example, the light
directly shines on the front of the
vehicle at sunrise or sunset). –
When a sudden change in bright-
ness occurs (for example, when
the vehicle enters or exits a tunnel
or under a bridge).
While the I-LI system is operating, you may
hear a sound of brake operation. This is
normal and indicates that the I-LI system is
operating properly.
SYSTEM TEMPORARILY
UNAVAILABLE
Condition A:
The warning and assist functions of the I-LI
system are not designed to work under the
following conditions:
• When you operate the lane change signal and change the traveling lanes in the di-
rection of the signal. (The I-LI system will
be deactivated for approximately 2 sec-
onds af ter the lane change signal is
turned off.)
• When the vehicle speed lowers to less than approximately 37 mph (60 km/h).
Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the warning and assist func-
tions will resume. Condition B:
The assist function of the I-LI system is not
designed to work under the following con-
ditions (warning is still functional):
• When the brake pedal is depressed.
• When the steering wheel is turned as far
as necessary for the vehicle to change
lanes.
• When the vehicle is accelerated during I-LI system operation.
• When the Intelligent Cruise Control (ICC) approach warning occurs.
• When the hazard warning flashers are operated.
• When driving on a curve at high speed.
Af ter the above conditions have finished
and the necessary operating conditions
are satisfied, the I-LI system application of
the brakes will resume.
Condition C:
If the following messages appear in the
vehicle information display, a chime will
sound and the I-LI system will be turned off
automatically.
• “Not Available - Poor Road Conditions”: When the Vehicle Dynamic Control (VDC)
system (except Traction Control System
[TCS] function) or ABS operates.
