Plug-in
indicator light
This light illuminates when the charge con-
nector is connected to the vehicle and
blinks during charging.
NOTE:
If the charge connector is connected to
the vehicle, the power switch cannot be
placed in the READY to drive position.
Power limitation
indicator light
When the power limitation indicator light is
illuminated, the power provided to the trac-
tion motor is reduced. Therefore the ve-
hicle is not as responsive when the accel-
erator is depressed while the power
limitation light is illuminated.
When this light comes on, the warning dis-
play appears within the vehicle information
display. Follow the instructions provided on
the vehicle information display.
This light illuminates in the following condi-
tions.
• Li-ion battery available charge is ex-tremely low • Li-ion battery temperature is very low
(approximately −4°F (−20°C)
• When the temperature of the EV system is high (motor, inverter, coolant system,
Li-ion battery etc.)
• When the EV system has a malfunction.
If the low battery charge indicator is illumi-
nated, charge the Li-ion battery as soon as
possible.
If this indicator illuminates because the Li-
ion battery is cold due to low outside tem-
peratures, move the vehicle to a warmer
location. The Li-ion battery temperature
may be increased by charging the Li-ion
battery.
If the light illuminates when the EV system
becomes hot due to continuous hill climb-
ing, either continue driving at a slower safe
speed or stop the vehicle in a safe location.
If this indicator does not turn off, have the
system checked. It is recommended that
you visit a NISSAN certified LEAF dealer for
this service.
The indicator illuminates when a part in the
EV system has malfunctioned. If the indica-
tor illuminates in a situation other than
those described above, or if it does not turn
off, there may be a system malfunction.
Have the system checked. It is recom- mended that you visit a NISSAN certified
LEAF dealer for this service.
WARNING
Power limitation mode can result in re-
duced power and vehicle speed. The re-
duced speed may be lower than other
traffic, which could increase the chance
of a collision. Be especially careful
when driving. If the vehicle cannot
maintain a safe driving speed, pull to
the side of the road in a safe area.
Charge the Li-ion battery if the charge
is low or allow the Li-ion battery to cool.
NOTE:
You can reduce charging time and keep
the Li-ion battery temperature lower if
you:
• Charge more frequently in smaller amounts, and
• Keep the battery at a higher level of charge.
READY to drive
indicator light
The READY to drive indicator light illumi-
nates when the EV system is powered and
the vehicle may be driven.

4. Push the power switch while depressingthe brake pedal within 10 seconds af ter
the chime sounds. The power switch
position changes to the READY to drive
mode.
Af ter step 3 is performed, if the power
switch is pushed without depressing the
brake pedal, the power switch position will
change to ACC.
NOTE:
• When the power switch is pushed to the ACC or ON position or READY to
drive mode by the above procedure,
the EV system operation for dis-
charged Intelligent Key system indica-
tor appears on the vehicle information
display even if the Intelligent Key is in-
side the vehicle. This is not a malfunc-
tion. To stop the warning indicator
from blinking, touch the power switch
with the Intelligent Key again.
• If the Intelligent Key battery discharge indicator appears on the vehicle infor-
mation display, replace the battery as
soon as possible. For additional infor-
mation, refer to “NISSAN Intelligent
Key® battery replacement” in the
“Maintenance and do-it-yourself ” sec-
tion of this manual.
NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the power switch to be placed
in the READY to drive position without the
use of the registered key.
If the power switch fails to place the vehicle
into the READY to drive position using the
registered key, it may be due to interfer-
ence caused by another registered key, an
automated toll road device or automated
payment device on the key ring. Restart the
EV system using the following procedure:
1. Leave the power switch in the ON posi- tion for approximately 5 seconds.
2. Place the power switch in the OFF posi- tion and wait approximately 10 seconds.
3. Repeat steps 1 and 2 again.
4. Place the power switch in the READY to drive position while holding the device
(which may have caused the interfer-
ence) separate from the registered key.
If this procedure allows the power
switch to be placed in the READY to drive
mode, NISSAN recommends placing the
registered key on a separate key ring to
avoid interference from other devices. • Make sure that the area around the ve-
hicle is clear.
• Check fluid levels such as coolant, brake fluid, and windshield-washer fluid as fre-
quently as possible.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Check that all doors are closed.
• Position the seat and adjust the head restraints/headrests.
• Adjust the inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of the warning lights when the power switch is pushed to the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual.
BEFORE STARTING THE EV SYSTEM
5-14Starting and driving

DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system. Refill
before operating the vehicle. For additional
information, refer to “Cooling system” in the
“Maintenance and do-it-yourself ” section
of this manual.
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced in
snowy and icy conditions. If you operate
your vehicle on snowy or icy roads, NISSAN
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels. It is
recommended that you visit a NISSAN cer-
tified LEAF dealer for the tire type, size,
speed rating and availability information.
For additional traction on icy roads, stud-
ded tires may be used. However, some U.S.
states and Canadian provinces prohibit
their use. Check local, state and provincial
laws before installing studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may
be poorer than that of non-studded
snow tires.Tire chains may be used. For additional in-
formation, refer to “Tire chains” in the “Main-
tenance and do-it-yourself ” section of this
manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
• A scraper and stiff-bristled brush to re-
move ice and snow from the windows
and wiper blades.
• A shovel to dig the vehicle out of snow- drif ts.
• Extra windshield-washer fluid to refill the reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
• Wet ice (32°F, 0°C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” un-
der these conditions. Try to avoid
driving on wet ice until the road is
salted or sanded. •
Whatever the conditions, drive with
caution. Accelerate and slow down
with care. If accelerating too fast, the
drive wheels will lose even more
traction.
• Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry
pavement.
• Allow greater following distances on
slippery roads.
• Watch for slippery spots (glare ice).
These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while on
the ice, and avoid any sudden steer-
ing maneuvers.
• Do not use cruise control on slippery
roads.
FREEING A FROZEN CHARGE PORT
LID
When the charge port is frozen, melt the ice
using a hair dryer.

and that the locks (if so equipped) hold
securely in all latched positions.
Seat belts:Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Steering wheel: Check for changes in the
steering conditions, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure
that all warning lights and chimes are op-
erating properly.
Windshield defroster: Check that the air
emits from the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check
that the wipers and washers operate prop-
erly and that the wipers do not streak.
Under hood and vehicle
The maintenance items listed here should
be checked periodically.
12-volt battery (except for maintenance
free batteries)*: Check the fluid level in
each cell. The fluid should be at the bottom of the filler opening. Vehicles operated in
high temperatures or under severe condi-
tions require frequent checks of the 12–volt
battery fluid level.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the EV system 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 high voltage parts are cold. Make
sure that the coolant level is between the
MAX and MIN lines on the reservoir.
Fluid leaks: Check under the vehicle for
water or other fluid leaks af ter the vehicle
has been parked for a while. Water dripping from the air conditioner af ter use is normal.
If you should notice any leaks, check for
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
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust will form on the
floor pan and frame. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information, re-
fer to “Cleaning exterior” in the “Appearance
and care” section of this manual.
Windshield-washer fluid*: Check that
there is an adequate amount of fluid in the
reservoir.
8-4Maintenance and do-it yourself

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions that should
be closely observed.
WARNING
• The EV system uses high voltage up
to approximately DC 400 volt. The
system can be hot during and af ter
starting and when the vehicle is shut
off. Be careful of both the high volt-
age and the high temperature. Obey
the labels that are attached to the
vehicle.
• Never disassemble, remove or re-
place high-voltage parts and cables
as well as their connectors. High-
voltage cables are colored orange.
• Disassembling, removing or replac-
ing those parts or cables can cause
severe burns or electric shock that
may result in serious injury or death.
The vehicle high-voltage system has
no user serviceable parts. It is recom-
mended that you visit a NISSAN cer-
tified LEAF dealer for any necessary
maintenance. •
Park the vehicle on a level surface,
apply the parking brake securely and
chock the wheels to prevent the ve-
hicle from moving. Push the P (Park)
position switch on the shif t lever or
place the vehicle into the N (Neutral)
position.
• If you must work with the EV (Electric
Vehicle) system is turned on, keep
hands, clothing, hair and tools away
from moving fans and any other
moving parts.
• Make sure that the power switch is in
the OFF or LOCK position when per-
forming any part replacement or
repairs.
• It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
• Always wear eye protection when-
ever you work on your vehicle.
• Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
• Keep smoking materials, flames and
sparks away from the 12-volt battery.
CAUTION
• Do not work under the hood while
the motor compartment is hot. Push
the power switch in the OFF position
and wait until it cools down.
• Avoid direct contact with used cool-
ant. Improperly disposed coolant
and/or other vehicle fluids can dam-
age the environment. Always con-
form to local regulations for the dis-
posal of vehicle fluids.
• Never connect or disconnect the bat-
tery or any transistorized compo-
nent while the power switch is in the
ON position.
• Your vehicle is equipped with an au-
tomatic cooling fan. It may come on
at any time without warning, even if
the power switch is not in the ACC, ON
or READY to drive position. To avoid
injury, always disconnect the nega-
tive 12-volt battery cable before
working near the fan.
• Before performing any electrical
maintenance work on the vehicle
such as the battery, fuses or bulb re-
placement, confirm the following:
– The charge connector is removed
from the vehicle.
