•When using a wheel without the
TPMS such as a spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on af ter 1 minute. Have the
system checked. It is recommended
that you visit a NISSAN certified LEAF
dealer as soon as possible for tire re-
placement and/or system resetting.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
CAUTION
• The TPMS is not a substitute for the
regular tire pressure check. Be sure
to check the tire pressure regularly.
• If the vehicle is being driven at
speeds of less than 16 mph (25 km/h),
the TPMS may not operate correctly.
• Be sure to install the specified size of
tires to the four wheels correctly.
Master warning light
There are two types of master warning
lights: yellow and red. These lights illumi-
nate if any warning lights or indicator lights
are illuminated or if various vehicle infor-
mation warnings appear in the vehicle in-
formation display.
This light illuminates when a yellow warn-
ing light within the vehicle information dis-
play is illuminated or when a message is
displayed on the vehicle information
display.
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
conditions. • 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.

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 placed in the ACC or ON position or READY to drive
mode by the above procedure, the EV
system operation for discharged Intel-
ligent Key system indicator appears on
the vehicle information display even if
the Intelligent Key is inside the vehicle.
This is not a malfunction. 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, see “NISSAN Intelligent Key®
battery replacement” (P. 8-19).
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,
see “Warning lights, indicator lights and
audible reminders” (P. 2-14).
BEFORE STARTING THE EV SYSTEM
Starting and driving5-13

CAUTION
To prevent damage to the Li-ion bat-
tery: Do not store the vehicle in tem-
peratures below -13°F (-25°C) for over
seven days. If the outside temperature
is -13°F (-25°C) or less, the Li-ion battery
may freeze and it cannot be charged or
provide power to run the vehicle. Move
the vehicle to a warm location.
NOTE:
• Connect the charger to the vehicle and place the power switch in the OFF po-
sition when parking the vehicle if tem-
peratures may go below -4°F (-20°C).
For models with 40 kWh battery
model, this provides external power to
the Li-ion battery warmer (if so
equipped) when it operates and does
not discharge the Li-ion battery. Ve-
hicle driving range is reduced if the Li-
ion battery warmer (if so equipped) op-
erates (Li-ion battery temperature
approximately -4°F (-20°C) or colder)
while driving the vehicle. You may need
to charge the Li-ion battery sooner
than in warmer temperatures.
• The Li-ion battery requires more time to charge when the Li-ion battery
warmer (if so equipped) operates. • The predicted charging time displayed
on the meter and navigation system (if
so equipped) increases when the Li-ion
battery warmer (if so equipped)
operates.
• Vehicle range may be substantially re- duced in extremely cold conditions (for
example under -4°F (-20°C)).
• Using the climate control system to heat the cabin when outside tempera-
ture is below 32°F (0°C) uses more elec-
tricity and affects vehicle range more
than when using the heater when the
temperature is above 32°F (0°C).
• Climate control performance is re- duced when using the Climate Ctrl.
Timer or Remote Climate Control while
the Li-ion battery warmer (if so
equipped) operates (for models with
40 kWh battery model). Set only the
charging timer [End Time] when charg-
ing in cold weather. The vehicle auto-
matically determines when to start
charging to fully charge the Li-ion bat-
tery, even if the Li-ion battery warmer
operates. Charging ends before the set
end time if the Li-ion battery is fully
charged.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock be-
comes frozen, heat the key before inserting
it into the key hole or use the remote key-
less entry key fob.
ANTIFREEZE
In the winter when it is possible that the
outside temperature will drop below 32°F
(0°C), check the antifreeze to ensure proper
winter protection. For additional informa-
tion, see “Cooling system” (P. 8-5).
12-VOLT BATTERY
If the 12-volt battery is not fully charged
during extremely cold weather conditions,
the 12-volt battery fluid may freeze and
damage the 12-volt battery. To maintain
maximum efficiency, the 12-volt battery
should be checked regularly. For additional
information, see “12-volt battery” (P. 8-9).
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, see “Cooling system” (P. 8-5).

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.
