WARNING
In case of a collision:
.If your vehicle is drivable, pull your
vehicle off the road, push the P
(Park) position switch on the selec-
tor lever, apply the parking brake
and turn the EV (Electric Vehicle)
system off.
. Check your vehicle to see if there
are exposed high-voltage parts or
cables. For their locations, see
“High-voltage components” earlier
in this section. To avoid personal
injury, never touch high-voltage wir-
ing, connectors, and other high-
voltage parts, such as inverter unit
and Li-ion battery. An electric shock
may occur if exposed electric wires
are visible when viewed from inside
or outside of your vehicle. There-
fore, never touch exposed electric
wires.
. If the vehicle receives a strong
impact to the floor while driving,
stop the vehicle in a safe location
and check the floor. .
Leaks or damage to the Li-ion
battery may result in a fire. If you
discover them, contact emergency
services immediately. Since the
fluid leak may be lithium manga-
nate from the Li-ion battery, never
touch the fluid leak inside or out-
side the vehicle. If the fluid contacts
your skin or eyes, wash it off
immediately with a large amount of
water and receive immediate medi-
cal attention to help avoid serious
injury.
. If a fire occurs in the EV (Electric
Vehicle) , leave the vehicle as soon
as possible. Only use a type ABC,
BC or C fire extinguisher that is
meant for use on electrical fires.
Using a small amount of water or
the incorrect fire extinguisher can
result in serious injury or death from
electrical shock.
. If your vehicle needs to be towed,
do it with the front wheels raised. If
the front wheels are on the ground
when towing, the traction motor
may generate electricity. This may
damage the components of the EV
(Electric Vehicle) system and cause a fire.
. If you are not able to safely assess
the vehicle due to vehicle damage,
do not touch the vehicle. Leave the
vehicle and contact emergency ser-
vices. Advise 1st responders that
this is an electric vehicle.
. In the event of an accident that
requires body repair and painting,
the vehicle should be delivered to a
NISSAN certified LEAF dealer to
have the Li-ion battery pack and
high voltage parts such as the
inverter, including the wiring har-
ness, removed prior to painting. Li-
ion battery packs exposed to heat in
the paint booth will experience
capacity loss. Damaged Li-ion bat-
tery packs may also pose safety
risks to untrained mechanics and
repair personnel.
ROAD ACCIDENT PRECAUTIONS

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 remin-
ders” in the “2. 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
possible.WARNING
.Pay special attention to pedes-
trians. Because there is no engine
noise, pedestrians 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)
system.
. Be sure to push the P (Park) posi-
tion switch on the selector lever and
apply the parking brake when park-
ing 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) position.
. Keep the brake pedal depressed
until you are ready to drive. When
the vehicle is in the D (drive) posi-
tion 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 serious injury or death.
NOTE:
. The vehicle cannot run with a dis-
charged Li-ion battery. Repeated accel-
eration 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 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
accelerator pedal is released, the re-
generative brake system provides
some deceleration.
. When you put the shift selector in the
ECO position and take your foot off the
accelerator pedal, more regenerative
brake is applied than in the D (Drive)
position.
. Less deceleration is provided by the
regenerative brake system when the Li-
EV OverviewEV-9
EV (Electric Vehicle)
CHARACTERISTICS

ion battery is fully charged. Regenera-
tive brake is automatically reduced
when the Li-ion battery is fully charged
to prevent the Li-ion battery from
becoming overcharged. Regenerating
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 da-
mage.
. 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 operation.
NOISE AND VIBRATION
You might experience the following noise or
vibration as a normal characteristic of this
vehicle.
.Traction motor noise from motor compart-
ment.
. Noise and vibration when releasing and
applying the electric parking brake.
. Water pump and radiator fan noise while
charging. .
Compressor and radiator fan noise when the
A/C-Heater Timer (Climate Ctrl. Timer) or
remote climate control is used.
. Relay operation noise and vibration at start-
up and shut-down of the EV (Electric
Vehicle) system (power switch placed in
the ON and OFF position) .
. Approaching Vehicle Sound for Pedestrians
(VSP) .
WARNING
The EV (Electric Vehicle) system uses a
high voltage current. Failure to follow
the proper handling instructions may
cause serious injury or death. Be sure
to read the “CH. Charging” section and
follow the procedures and guidelines
described.
LIFE WITH AN EV (scene guide)

To start charging:
1. Push the P position switch to place thevehicle in the P (Park) position and apply the
electric parking brake.
2. When charging the Li-ion battery, place the power switch in the OFF position. When the
power switch is in the ON position, the Li-
ion battery will not start charging.
3. Open the charge port lid and charge port cap. See “Charge port lid” and “Charge port
cap” in the “3. Pre-driving checks and
adjustments” section.
CAUTION
.Be sure to insert the charge con-
nector straight into the quick charge
port right up to the base. Failure to
do so may result in the Li-ion battery
not charging or could cause damage
to the charging equipment.

CHECKING BULBS
With all doors closed, apply the parking brake,
and push the power switch in the ON position.
The following lights will illuminate (if so
equipped):

Low brake fluid warning light:
When the power switch is in the ON position,
the light warns of a low brake fluid level. If this
warning light illuminates, the Vehicle Dynamic
Control (VDC) warning light and the brake
system warning light (yellow) also illuminate.
If the light illuminates while the power switch is
in the READY to drive position with the parking
brake not applied, stop the vehicle and perform
the following items.
1. Check the brake fluid level. If brake fluid isnecessary, add fluid and have the system
checked by a NISSAN certified LEAF dealer.
See “Brake fluid” in the “8. Maintenance and
do-it-yourself” section.
2. If the brake fluid level is correct, have the warning system checked by a NISSAN
certified LEAF dealer.

CAUTION
.Be sure to carry the Intelligent Key
with you when operating the vehi-
cle.
. Never leave the Intelligent Key in
the vehicle when you leave the
vehicle.
The Intelligent Key is always communicating with
the vehicle because it receives radio waves. The
Intelligent Key system transmits weak radio
waves. Environmental conditions may interfere
with the operation of the Intelligent Key system
under the following operating conditions.
. When operating near a location where
strong radio waves are transmitted, such
as a TV tower, power station or broad-
casting station.
. When in possession of wireless equipment,
such as a cellular phone, transceiver or CB
radio.
. When the Intelligent Key is in contact with or
covered by metallic materials.
. When any type of radio wave remote control
is used nearby. .
When the Intelligent Key is placed near an
electric appliance such as a personal
computer.
. When the vehicle is parked near a parking
meter.
In such cases, correct the operating conditions
before using the Intelligent Key function or use
the mechanical key.
Although the life of the battery varies depending
on the operating conditions, the battery’s life is
approximately 2 years. If the battery is dis-
charged, replace it with a new one.
When the Intelligent Key battery is almost
discharged, firmly apply the foot brake and
touch the power switch with the Intelligent Key.
Then push the power switch while depressing
the brake pedal within 10 seconds after the
chime sound.
Since the Intelligent Key is continuously receiv-
ing radio waves, if the key is left near equipment
that transmits strong radio waves, such as
signals from a TV or personal computer, the
battery life may become shorter.
For information regarding replacement of a
battery, see “Intelligent Key battery replacement”
in the “8. Maintenance and do-it-yourself”
section. Pay special attention that the vehicle battery is
not completely discharged.
As many as 4 Intelligent Keys can be registered
and used with one vehicle. For information about
the purchase and use of additional Intelligent
Keys, contact a NISSAN certified LEAF dealer.
